1.	B. Nutley, Sissela, et al. (författare) COVID-19 Restrictions Resulted in Both Positive and Negative Effects on Digital Media Use, Mental Health, and Lifestyle Habits 2023 Ingår i: International Journal of Environmental Research and Public Health. - 1660-4601. ; 20:6 Tidskriftsartikel (refereegranskat)abstract While studies have reported effects on digital media during the COVID-19 restrictions, few have included data prior to the pandemic, and most have only measured screen time. We therefore investigated changes in specific digital media activities, as well as mental health and lifestyle habits, in a longitudinal study of adolescents spanning from before the pandemic (T1) to one month into restrictions (T2) and one year later when schools had reopened (T3). Adolescents (16–19 years) rated smartphone use, problematic/addictive media use, negative experiences (e.g., victimization), mental health (i.e., irritability, stress, and closeness), and protective lifestyle habits (i.e., sleep and exercise). Results showed initial decreases in irritability and negative digital experiences, increases in sleep and exercise, as well as a decrease in closeness during remote learning (T2). However, these changes returned to, or superseded, their initial levels at follow-up (T3). There were also increases in digital media use and stress at T3. Conclusively, by investigating specific digital media activities and collecting data both prior to and during different phases of the pandemic, we were able to find both positive and negative effects.

(författare) Evidence of a two-factor structure for Internet Gaming Disorder and Social Media Disorder: Psychometric properties of a new screening instrument for adolescents and adults 2023 Ingår i: Journal of Psychopathology and Behavioral Assessment. - 0882-2689 .- 1573-3505. ; 45 Tidskriftsartikel (refereegranskat)abstract Currently, there is no screening instrument available for assessing both internet gaming disorder (IGD) and social media disorder (SMD). This study aimed to examine the reliability and factor structure of a new screening instrument for adolescents and adults, the Gaming and Social Media Questionnaire (GSMQ-9), and to investigate its association with psychosocial outcomes (i.e., psychosomatic problems, self-concept, and social problems for adults and quality of life for adolescents). Survey data were collected from 995 university students and 626 adolescents. Results showed that a two-factor solution, representing Heavy Involvement and Negative Consequences, had a better model fit compared to a one-factor solution for both IGD and SMD and for both adolescents and adults. The internal consistency was acceptable, and the test-retest reliability was excellent. Negative Consequences were significantly more strongly related to all psychosocial outcomes compared to Heavy Involvement. The proportion of participants meeting the DSM-5 symptom criteria according to self-ratings on the GSMQ-9 was 1.4% (adolescents) and 1.8% (adults) for IGD and 2.6% (adolescents) and 4.0% (adults) for SMD. Conclusively, the GSMQ-9 appears to be a reliable two-factor screening instrument for IGD and SMD among adults and adolescents.
3.	Burén, Jonas, 1984, et al. (författare) Gaming and Social Media Addiction in University Students: Sex Differences, Suitability of Symptoms, and Association With Psychosocial Difficulties 2021 Ingår i: Frontiers in Psychiatry. - : Frontiers Media SA. - 1664-0640. ; 12 Tidskriftsartikel (refereegranskat)abstract Background: Previous research has shown that addictions to digital media can have negative impact on psychosocial health. Although Internet Gaming Disorder (IGD) has received most scholarly recognition, the potential negative consequences of Social Media Disorder (SMD) have also been found. However, few studies have assessed the symptoms of these two digital media addictions in the same way, making comparisons difficult. The present study aims to fill this gap by investigating differences and similarities regarding how common the symptoms are, sex differences, the suitability of the symptoms, and their association with psychosocial difficulties. Method: A total of 688 university students (63.2% women, Mean age = 25.98) completed a questionnaire measuring symptoms of IGD and SMD, as well as psychosocial difficulties (i.e., psychosomatic symptoms, low self-concept, and social problems). Results: Results showed that 1.2% of the men and 0.9% of the women met the symptom criteria for IGD (non-significant difference), whereas 3.2% men and 2.8% women met the symptom criteria for SMD (non-significant difference). Dimensional analyses indicated that men had higher IGD scores compared to women, whereas the opposite was found for SMD. Symptoms of heavy involvement in digital media (i.e., Preoccupation, Tolerance, Withdrawal, Unsuccessful attempts to control, and Escape) had high sensitivity, but low positive predictive value (PPV). However, symptoms associated with negative consequences of digital media use (i.e., Loss of interest, Continued excessive use, Deception, and Jeopardizing career/relationships) had low sensitivity, but high PPV. These symptom patterns were similar for IGD and SMD. Meeting the criteria for IGD or SMD as well as being at risk of these disorders were significantly associated with psychosocial difficulties. Symptoms of SMD generally had stronger associations with psychosomatic symptoms compared to symptoms of IGD. Conclusions: We conclude that heavy involvement in digital media seems common among individuals with IGD or SMD, but also among those not meeting the symptom criteria, whereas negative consequences are less common but highly predictive of digital media addictions once present. Further attention to SMD is warranted, as it seems more common than IGD and also seems to be equally or more strongly associated with psychosocial difficulties.
4.	Burén, Jonas, 1984, et al. (författare) Screen time and addictive use of gaming and social media in relation to health outcomes 2023 Ingår i: Frontiers in Psychology. - 1664-1078. ; 14 Tidskriftsartikel (refereegranskat)abstract Introduction: This study examined associations between screen time and addictive use (i.e., heavy involvement and negative consequences) of gaming and social media, and their independent effects on health outcomes. Methods: Survey data were collected from 2,265 participants (mean age = 21.57). Internet Gaming Disorder (IGD) and Social Media Disorder (SMD) were measured with the Gaming and Social Media Questionnaire (GSMQ-9), with separate measures for heavy involvement and negative consequences. Screen time was measured by weekly hours of gaming and social media. Assessed health outcomes were psychological problems, low self-concept, social problems, sleep problems, and sleep time. Results: Screen time and addictive use were significantly associated for both gaming and social media, with associations being stronger for symptoms of heavy involvement compared to symptoms of negative consequences. However, despite significant associations, a substantial proportion of the participants with a high screen time did not meet any or just one symptom of addiction. More importantly, it was primarily negative consequences that had independent effects on health outcomes, except for sleep. High levels of heavy involvement in gaming, were even related to lower, not higher, levels of psychological problems. Conclusion: The present findings study show that screen time is a poor indicator of addictive use of gaming and social media. Given that it was primarily negative consequences of gaming or social media that had effects on health outcomes, our study also emphasizes the need to distinguish between different types of addictive use and to further examine the diagnostic validity of the nine IGD symptom criteria.
5.	Soares, Lorrayne, et al. (författare) The role of executive function deficits, delay aversion and emotion dysregulation in internet gaming disorder and social media disorder: Links to psychosocial outcomes. 2023 Ingår i: Journal of Behavioral Addictions. - : Akademiai Kiado Zrt.. - 2062-5871 .- 2063-5303. ; 12:1 Tidskriftsartikel (refereegranskat)abstract It has been argued that it is important to consider underlying mechanisms of mental health problems. Previous studies have shown that executive deficits, delay aversion, and emotion dysregulation are related to Internet Gaming Disorder (IGD) and Social Media Disorder (SMD). However, the present study is the first to investigate whether these neuropsychological deficits show additive effects or if they interact. The present study also investigated whether these deficits mediate the association between IGD/SMD and psychosocial outcomes.The study involved 995 university students who completed a survey measuring IGD/SMD symptom severity, neuropsychological functions, and psychosocial outcomes. Both dimensional and categorical analyses were used to assess the associations between neuropsychological functions and IGD/SMD. Simple and multiple mediation analyses were conducted to examine if neuropsychological functioning mediates the association between IGD/SMD and psychosocial outcomes.All neuropsychological functions were significantly associated with both IGD and SMD symptom severity. However, only inhibition and emotion regulation, as well as delay aversion for SMD, remained significant when controlling for the overlap between different functions. Associations were significantly stronger for men compared to women for IGD. In the categorical analyses, individuals with IGD/SMD were more likely to have neuropsychological deficits (odds ratios between 3.33 and 8.81). Finally, all neuropsychological functions, except inhibition, were significant mediators in the link between IGD/SMD and psychosocial outcomes.These results shed light on the neuropsychological underpinnings of IGD/SMD, which can be used to identify more homogenous subgroups and provide more individualized treatment options.
6.	Thorell, Lisa B., et al. (författare) Distance learning during the COVID-19 pandemic for children with ADHD and/or ASD : a European multi-center study examining the role of executive function deficits and age 2022 Ingår i: Child and Adolescent Psychiatry and Mental Health. - : BioMed Central (BMC). - 1753-2000. ; 16:1 Tidskriftsartikel (refereegranskat)abstract Background: One of the COVID-19 pandemic consequences that has affected families the most is school lockdowns. Some studies have shown that distance learning has been especially challenging for families with a child with neurodevelopmental disorders such as ADHD or ASD. However, previous studies have not taken the heterogeneity of these disorders into account. The aim of the present study was therefore to investigate differences between families with a child with ADHD, ASD, or both conditions, and to examine the role of underlying deficits in executive functioning (EF) in both children and parents in relation to negative and positive effects of distance learning. Methods: Survey data assessing both negative and positive experiences of distance learning were collected from parents with a child aged 5-19 years in seven Western European countries: the UK, Germany, Spain, Sweden, the Netherlands, Italy, and Belgium. Altogether, the study included 1010 families with a child with ADHD and/or ASD and an equally large comparison group of families with a child without mental health problems. We included measures of three different types of negative effects (i.e., effects on the child, effects on the parent, and lack of support from school) and positive effects on the family. Results: Results confirmed that families with a child with ADHD, ASD or a combination of ADHD and ASD showed higher levels of both negative and positive effects of distance learning than the comparison group. However, few differences were found between the clinical groups. Group differences were more pronounced for older compared to younger children. Regarding the role of both ADHD/ASD diagnosis and EF deficits, primarily children's EF deficits contributed to high levels of negative effects. Parent EF deficits did not contribute significantly beyond the influence of child EF deficits. Families of children with ADHD/ASD without EF deficits experienced the highest levels of positive effects. Conclusions: School closings during COVID-19 have a major impact on children with EF problems, including children with neurodevelopmental disorders. The present study emphasizes that schools should not focus primarily on whether a student has a neurodevelopmental disorder, but rather provide support based on the student's individual profile of underlying neuropsychological deficits.
7.	Thorell, Lisa B., et al. (författare) Longitudinal associations between digital media use and ADHD symptoms in children and adolescents: a systematic literature review 2022 Ingår i: European Child and Adolescent Psychiatry. - : Springer Science and Business Media LLC. - 1018-8827 .- 1435-165X. Forskningsöversikt (refereegranskat)abstract Previous reviews have often shown a link between digital media ADHD symptom levels. However, longitudinal studies are needed to find stronger evidence of a causal effect as well as to determine the direction of effects. The aim of the present review (PROSPERO CRD42021262695) was therefore to provide a systematic review of studies meeting the following inclusion criteria: (1) include longitudinal data investigating associations between digital media (i.e., gaming and social media) and later ADHD symptoms or vice versa, (2) be published within the past 10years (i.e., 2011 until June 2021), (3) be published in a peer-reviewed journal in English, and (4) include children or adolescents (age 0–17years). After a systematic search in the Web of Science and PsycInfo databases, we included 28 studies, all with adequate or high quality. Results showed support for reciprocal associations between digital media and ADHD symptoms, with associations being more consistent for problematic use of digital media than for screen time. Thus, children with ADHD symptoms appear more vulnerable to developing high or problematic use of digital media (i.e., selection effects), and digital media also have effects on later ADHD symptom levels, either because of specific characteristics of digital media or because of indirect effects on, for example, sleep and social relations (i.e., media effects). However, it should be emphasized that further studies investigating potential moderators and mediators are needed if we are to better understand the complex associations between digital media and ADHD symptom levels.

(författare) Disorganized Attachment and Inhibitory Capacity : Predicting Externalizing Problem Behaviors 2012 Ingår i: Journal of Abnormal Child Psychology. - : Springer Science and Business Media LLC. - 0091-0627 .- 1573-2835. ; 40:3, s. 449-458 Tidskriftsartikel (refereegranskat)abstract The aim of the present study was to investigate whether attachment insecurity, focusing on disorganized attachment, and the executive function (EF) component of inhibition, assessed at age 5, were longitudinally related to general externalizing problem behaviors as well as to specific symptoms of ADHD and Autism spectrum disorder (ASD), and callous-unemotional (CU) traits. General externalizing problem behaviors were also measured at age 5 to allow for a developmental analysis. Outcome variables were rated by parents and teachers. The sample consisted of 65 children with an oversampling of children with high levels of externalizing behaviors. Attachment was evaluated using a story stem attachment doll play procedure. Inhibition was measured using four different tasks. The results showed that both disorganized attachment and poor inhibition were longitudinally related to all outcome variables. Controlling for initial level of externalizing problem behavior, poor inhibition predicted ADHD symptoms and externalizing problem behaviors, independent of disorganized attachment, whereas for ASD symptoms no predictive relations remained. Disorganized attachment independently predicted CU traits.
9.	Bolk, Jenny, et al. (författare) Association of Perinatal and Childhood Ischemic Stroke With Attention-Deficit/Hyperactivity Disorder 2022 Ingår i: JAMA Network Open. - : American Medical Association. - 2574-3805. ; 5:4 Tidskriftsartikel (refereegranskat)abstract IMPORTANCE Early detection of attention-deficit/hyperactivity disorder (ADHD) plays a crucial role in reducing negative effects on everyday life, including academic failure and poor social functioning. Children who survive ischemic strokes risk major disabilities, but their risk of ADHD has not been studied in nationwide cohorts. OBJECTIVE To assess the risk of ADHD in children after pediatric ischemic stroke. DESIGN, SETTING, AND PARTICIPANTS Participants in this Swedish nationwide cohort study included 1320 children diagnosed with ischemic stroke recorded in linked Swedish national registers from January 1, 1969, to December 31, 2016, without prior ADHD diagnosis. Ten matched controls were identified for each index case, and first-degree relatives were identified for index individuals and controls. Analyses were stratified by perinatal and childhood strokes and presence of comorbid adverse motor outcomes and/or epilepsy. End of follow-up was the date of ADHD diagnosis, death, or December 31, 2016, whichever occurred first. Data analyses were performed August 1 to 28, 2021. EXPOSURES Pediatric ischemic stroke. MAIN OUTCOMES AND MEASURES Attention-deficit/hyperactivity disorder identified using codes from the International Classification of Diseases, Ninth Revision, and international Statistical Classification of Diseases and Related Health Problems, Tenth Revision, and/or prescribed ADHD medication recorded in the Medical Birth Register, National Patient Register, or Prescribed Drug Register after stroke. Cox proportional hazards regression was used to assess adjusted hazard ratios (aHRs) for ADHD after pediatric stroke, adjusting for parental age and ADHD in first-degree relatives. RESULTS Of 1320 children with stroke included in the analysis (701 boys [53.1%]), 75 (45 boys [60.0%]) were diagnosed with ADHD after stroke compared with 376 (252 boys [67.0%]) among the controls (aHR, 2.00 [95% CI, 1.54-2.60]). The risk was increased after both perinatal (aHR, 2.75 [95% CI, 1.65-4.60]) and childhood (aHR, 1.82 [95% CI, 1.34-2.48]) strokes and were similar if children born preterm or small for gestational age were excluded. Compared with controls, risks of ADHD were higher among children with perinatal stroke and adverse motor outcomes and/or epilepsy (aHR, 6.17 [95% CI, 2.80-13.62]) than among those without these comorbidities (aHR, 1.65 [95% CI, 0.80-3.42]). However, findings were similar in childhood stroke for children with adverse motor outcomes and/or epilepsy (aHR, 1.80 [95% CI, 1.12-2.89]) and among those without these comorbidities (aHR, 1.92 [95% CI, 1.28-2.90]). CONCLUSIONS AND RELEVANCE This cohort study of 1320 children with pediatric ischemic stroke suggests that there is an increased risk of ADHD. particularly in children with adverse motor outcomes and/or epilepsy, compared with controls. The risk increases after childhood strokes regardless of comorbidities.

(författare) Early concurrent and longitudinal symptoms of ADHD and ODD : Relations to different types of inhibitory control and working memory 2007 Ingår i: Journal of Child Psychology and Psychiatry. - : Wiley. - 0021-9630 .- 1469-7610. ; 48:10, s. 1033-1041 Tidskriftsartikel (refereegranskat)abstract Background: The aim of the present study was to investigate how three different types of inhibitory control - interference control within task, interference control outside task, and prepotent response inhibition - and two types of working memory - verbal and spatial - would relate to early symptoms of attention deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD), both concurrently and longitudinally. Methods: Seventy-two preschoolers, 1/3 who had been identified as being at risk for developing ADHD and/or ODD, completed neuropsychological tasks designed to measure inhibitory control and working memory. Behavioral symptoms were measured through parental and teacher ratings of the DSM-IV criteria for ADHD and ODD. Results: Our results suggest distinct types of inhibitory control as being good predictors of concurrent and longitudinal symptoms of ADHD, rather than ODD. However, no associations were obtained between working memory and ADHD or ODD symptoms either concurrently or longitudinally. Conclusions: This study emphasizes the need to isolate complex executive processes and break them down into components in order to properly understand the neuropsychological roots involved in ADHD and ODD.
11.	Brocki, Karin C., et al. (författare) Interrelations Between Executive Function and Symptoms of Hyperactivity/Impulsivity and Inattention in Preschoolers : A Two Year Longitudinal Study 2010 Ingår i: Journal of Abnormal Child Psychology. - : Springer Science and Business Media LLC. - 0091-0627 .- 1573-2835. ; 38:2, s. 163-171 Tidskriftsartikel (refereegranskat)abstract The present study, including children at risk for developing Attention Deficit Hyperactivity Disorder (ADHD), examined the idea that complex executive functions (EFs) build upon more simple ones. This notion was applied in the study of longitudinal interrelations between core EF components - simple and complex inhibition, selective attention, and working memory (WM) - at age 5 and 6 as well as their predictive relations to ADHD symptoms at age 7. The results showed that simple inhibition and selective attention at age 5 independently predicted complex inhibition and WM at age 6. In addition, EFs primarily predicted symptoms of inattention rather than hyperactivity/impulsivity even at this young age. Finally, age 6 complex inhibition was shown to act as a mediator in the relations between simple inhibition and selective attention at age 5 and symptoms of inattention at age 7. These findings provide novel longitudinal support for the theory that fundamental EF components show a progression with age toward more complex executive control (see Garon et al. Psychological Bulletin 134(1):31-60 2008). Further, complex inhibition, implicating both inhibition and WM, seems to be a particularly strong correlate of ADHD symptoms in young children and should as such be the focus of future studies examining the relation between cognitive function and ADHD symptoms from a developmental perspective.

(författare) Cognitive profiles of extremely preterm children : Full-Scale IQ hides strengths and weaknesses 2021 Ingår i: Acta Paediatrica. - : John Wiley & Sons. - 0803-5253 .- 1651-2227. ; 110:6, s. 1817-1826 Tidskriftsartikel (refereegranskat)abstract Aim: To study whether a specific cognitive profile can be identified for children born extremely preterm (EPT) by investigating: 1) strengths and weaknesses not revealed by Full-Scale IQ, 2) overlap between different cognitive deficits and 3) proportion of EPT children with multiple deficits.Methods: We analysed data from the 4th version of Wechsler Intelligence Scales for Children in EPT children (n = 359) and matched controls (n = 367), collected within the 6.5-year follow-up of a population-based prospective cohort study.Results: Extremely preterm children performed worse than controls on all measures. Group differences were the largest in Perceptual Reasoning (PRI) and Working Memory (WMI), but differences between indices were small. However, when conducting categorical analyses, deficits in PRI and/or WMI were not more common than other combinations. Many EPT children had no or mild cognitive deficits, although often in multiple domains.Conclusion: Extremely preterm children had greater weaknesses in working memory and perceptual abilities. However, detailed analyses of cognitive subscales showed large heterogeneity and provided no support for a specific cognitive profile. In conclusion, Full-Scale IQ scores hide strengths and weaknesses and individual profiles for EPT children need to be considered in order to provide appropriate support.
13.	Lindqvist, Sofia, et al. (författare) Brief Report : Manipulation of Task Difficulty in Inhibitory Control Tasks 2009 Ingår i: Child Neuropsychology. - : Informa UK Limited. - 0929-7049 .- 1744-4136. ; 15:1, s. 1-7 Tidskriftsartikel (refereegranskat)abstract The present study investigated how task difficulty can be manipulated in inhibitory control tasks. Tasks from three widely used task paradigms a Go/No-Go task, a Stop-Signal task, and a Flanker task were manipulated on two parameters each (Go/No-Go task: interstimulus interval, prepotency. Stop-signal task: stop-signal-delay, prepotency. Flanker task: number of distractors, size of target stimulus). Participants were 86 children (age 4-6) from a population-based sample. The results showed no significant effects on the Go/No-Go task but both main and interaction effects on the Stop-Signal task and the Flanker task. Together, these findings indicate that task difficulty can be successfully manipulated in inhibitory control tasks. However, the interactive rather than additive effects on performance suggest that the level of one parameter only has the desired effect under certain conditions. This new information about how to manipulate task difficulty is important when adapting tasks for use with children of different ages, as well as when designing training programs for improving inhibitory control among children with ADHD.

(författare) Parental monitoring in late adolescence : Relations to ADHD symptoms and longitudinal predictors 2015 Ingår i: Journal of Adolescence. - : Wiley. - 0140-1971 .- 1095-9254. ; 40, s. 24-33 Tidskriftsartikel (refereegranskat)abstract In this study, we aimed to replicate Stattin and Kerr's (2000) study on parental monitoring and adolescents' deviant behavior, to extend their findings to ADHD symptoms, and to examine the longitudinal predictors (8-18 years) of parental knowledge and child disclosure. Results showed that conduct problems were primarily associated with parental knowledge and child disclosure, but not with parental solicitation and control. A similar pattern was observed for ADHD symptoms. However, while the relations for conduct problems were generally independent of ADHD symptoms, the relations for ADHD symptoms were primarily non-significant after controlling for conduct problems. Moreover, early behavior problems, but not insecure/disorganized attachment, were associated with parental knowledge and child disclosure in adolescence. In conclusion, child disclosure is primarily associated with deviant behavior rather than ADHD, and early child problem behavior is a more important predictor of child disclosure (implicating reciprocal relations between these two constructs) than is insecure/disorganized attachment.
15.	Scholtens, Sara, et al. (författare) ADHD Symptoms and Attachment Representations : Considering the Role of Conduct Problems, Cognitive Deficits and Narrative Responses in Non-Attachment-Related Story Stems 2014 Ingår i: Journal of Abnormal Child Psychology. - : Springer Science and Business Media LLC. - 0091-0627 .- 1573-2835. ; 42:6, s. 1033-1042 Tidskriftsartikel (refereegranskat)abstract The overall aim of the present study was to investigate ADHD symptoms in relation to attachment representations. We used both attachment- and non-attachment-related story stems, which allowed us to investigate whether problems with narrative production can explain the relation between ADHD symptoms and attachment representations. We also investigated the role of cognitive deficits and conduct problems in these relations. The sample consisted of 89 children (27 % girls) between 6 and 10 years old, with an oversampling of children with high levels of ADHD symptoms. ADHD symptoms and conduct problems were rated by parents and teachers. Cognitive functioning was investigated using laboratory tests of inhibition, working memory and sustained attention. Attachment representations were coded as secure, organized insecure and disorganized categories. Narrative responses to non-attachment-related story stems were coded for incoherence and negative content. Results showed that children in the disorganized attachment category had significantly higher levels of ADHD symptoms compared to those in the secure category. Both ADHD symptoms and disorganized attachment were related to incoherence and negative content. Attachment representations were not associated with ADHD symptoms when controlling for negative content in response to non-attachment-related story stems. These results suggest that the associations between attachment security and ADHD are yet to be fully understood. Importantly, a propensity to envisage negative events seems to characterize children with high levels of ADHD symptoms.

(författare) Multiple deficits in ADHD : executive dysfunction, delay aversion, reaction time variability, and emotional deficits 2013 Ingår i: Journal of Child Psychology and Psychiatry. - : Wiley. - 0021-9630 .- 1469-7610. ; 54:6, s. 619-627 Tidskriftsartikel (refereegranskat)abstract Background: The notion that ADHD constitutes a heterogeneous disorder is well accepted. However, this study contributes with new important knowledge by examining independent effects of a large range of neuropsychological deficits. In addition, the study investigated whether deficits in emotional functioning constitute a dissociable component of ADHD. Method: The study included children with ADHD (n=102; 713years) and a control sample individually matched with regard to age and gender. The administered tasks were designed to tap into three different neuropsychological domains: executive functions (i.e., working memory, inhibition, and shifting), delay aversion, and reaction time variability. Parent ratings of emotion regulation and a test of emotion recognition were also included. Results: Children with ADHD differed significantly from controls on all measures, except for delay aversion and recognition of disgust. No main effects of gender or interaction effects of gender and group were found. More importantly, executive functioning, reaction time variability, and emotional functioning all contributed independently to distinguishing between children with ADHD and controls. Conclusions: The current study supports the view of ADHD as a heterogeneous disorder related to multiple neuropsychological deficits. In addition, emotional functioning appears to be an area of importance for ADHD that needs to be incorporated into future theoretical models.
17.	Sjöwall, Douglas, et al. (författare) Neuropsychological deficits in preschool as predictors of ADHD symptoms and academic achievement in late adolescence 2017 Ingår i: Child Neuropsychology. - : Informa UK Limited. - 0929-7049 .- 1744-4136. ; 23:1, s. 111-128 Tidskriftsartikel (refereegranskat)abstract High levels of ADHD symptoms are related to severe negative outcomes, which underscore the importance of identifying early markers of these behavior problems. The main aim of the present study was therefore to investigate whether neuropsychological deficits in preschool are related to later ADHD symptoms and academic achievement, over and above the influence of early ADHD symptom levels. The present study is unique because it includes a broader range of predictors compared to previous studies and the participants are followed over time for as long as 13 years (i.e., ages 5 – 18 years). Preschool data included measures of executive functioning and reaction time variability as well as emotional reactivity and emotion regulation of both positive and negative emotions. When controlling for early ADHD symptom levels, working memory, reaction time variability, and regula- tion of happiness/exuberance were significantly related to inattention whereas regulation of happiness/ exuberance and anger reactivity were significantly related to hyperactivity/impulsivity. Furthermore, working memory and reaction time variability in preschool were significantly related to academic achievement in late adolescence beyond the influence of early ADHD symptoms. These findings could suggest that it is possible to screen for early neuropsychological deficits and thereby identify children who are at risk of negative outcomes. Furthermore, our results suggest that interventions need to look beyond executive functioning deficits in ADHD and also target the role of emotional functioning and reaction time variability. The importance of including both the positive and negative aspects of emotional functioning and distinguishing between emotion regulation and emotional reactivity was also demonstrated.

(författare) Childhood Executive Function Inventory (CHEXI) : A promising measure for identifying young children with ADHD? 2010 Ingår i: Journal of Clinical and Experimental Neuropsychology. - : Informa UK Limited. - 1380-3395 .- 1744-411X. ; 32:1, s. 38-43 Tidskriftsartikel (refereegranskat)abstract The present study investigated whether the Childhood Executive Function Inventory (CHEXI) can discriminate between young children fulfilling the diagnostic criteria for attention-deficit/hyperactivity disorder (ADHD) and normally developing children. Unlike other executive function rating instruments, the CHEXI focuses specifically on inhibitory control and working memory, without including items that overlap with the diagnostic criteria of ADHD. The CHEXI was found to discriminate very well between children fulfilling the criteria for ADHD and normally developing children, also when controlling for the effect of IQ and socioeconomic status (SES). Both sensitivity and specificity of the two CHEXI subscales were shown to be high using either parent or teacher ratings. The highest overall classification rate was found for parent ratings on the inhibition subscale, with sensitivity and specificity reaching 93.3. To summarize, the CHEXI should be considered a promising measure for identifying young children with ADHD, although it is for future research to determine whether the CHEXI can be successfully used to also discriminate between different psychopathological groups.
19.	Thorell, Lisa B. (författare) Do delay aversion and executive function deficits make distinct contributions to the functional impact of ADHD symptoms? : A study of early academic skill deficits 2007 Ingår i: Journal of Child Psychology and Psychiatry. - : Wiley. - 0021-9630 .- 1469-7610. ; 48:11, s. 1061-1070 Tidskriftsartikel (refereegranskat)abstract Background: The present study examined the distinct properties of executive functioning in relation to ADHD symptoms, as well as functional outcomes associated with ADHD. In line with the dual-pathway model of ADHD, executive functioning and delay aversion were expected to show independent effects on ADHD symptoms. Furthermore, relations to early academic skills were examined, and it was hypothesized that the two processes of the dual-pathway model can be differentiated in terms of their effect on academic skill deficits, such that EF deficits, but not delay aversion, mediate the link between ADHD and academic functioning. Results: As hypothesized, both EF deficits and delay aversion were independently related to ADHD symptoms. However, when conducting separate analyses for the two ADHD symptom domains, only the effect of EF deficits was independently related to symptoms of inattention, whereas only the effect of delay aversion was independently related to symptoms of hyperactivity/ impulsivity. The mediation analysis showed that EF deficits, but not delay aversion, act as a mediator in the relation between symptoms of inattention and both mathematics and language skills. In addition, there was also a significant direct effect of inattention on early academic skills. Conclusions: The findings of the present study are of importance for current models of heterogeneity in ADHD as they 1) provide further support for the notion that EF deficits and delay aversion are two possible pathways to ADHD, 2) add new interesting knowledge by showing that EF deficits and delay aversion can be differentiated in terms of their relations to the two ADHD symptom domains, and 3) indicate that the two processes of the dual-pathway model can also be differentiated in terms of their effect on functional impairments associated with ADHD.

(författare) Emotion dysregulation in adult ADHD: Introducing the Comprehensive Emotion Regulation Inventory (CERI) 2020 Ingår i: Journal of Clinical and Experimental Neuropsychology. - : TAYLOR & FRANCIS INC. - 1380-3395 .- 1744-411X. ; 42:7, s. 747-758 Tidskriftsartikel (refereegranskat)abstract Introduction Previous research has shown that Attention-Deficit Hyperactivity Disorder (ADHD) is linked to emotion dysregulation, but we still do not know enough about the specific nature of this deficit. The aim of the present study was therefore to study emotion dysregulation in adult ADHD using a new self-rating instrument, the Comprehensive Emotion Regulation Inventory (CERI). Methods The study included 390 participants, both adults diagnosed with ADHD and a comparison group. The CERI was created based on Gross process model of emotion. Unlike instruments already available, the CERI enables a detailed analysis of different strategies for regulating both positive and negative emotions and of the impact emotion dysregulation has on daily life. Results Results showed that the CERI has good psychometric properties, and a 5-factor solution was identified. Adults with ADHD differed from the comparison group with regard to how often they use different strategies, although effect sizes were small to medium. However, large effect sizes were found between ADHD and the comparison group with regard to problems implementing the use of various regulatory strategies and the negative impact on daily life functioning with regard to friendships, work/studies, or romantic relations. Within-group differences showed that adults with ADHD use the less advanced strategy suppression significantly more often compared to the more advanced strategies attentional deployment and reappraisal. Conclusions The CERI appears to be a valuable instrument for gaining more in-depth insights into emotion dysregulation in adults with mental disorders. Future research needs to examine what aspects of emotion dysregulation are shared between different mental disorders and what aspects might be specifically related to ADHD.

(författare) Emotional functioning, ADHD symptoms, and peer problems : A longitudinal investigation of children age 6-9.5years 2017 Ingår i: Infant and Child Development. - : Wiley. - 1522-7227 .- 1522-7219. ; 26:4 Tidskriftsartikel (refereegranskat)abstract The aim of the present study was to investigate the interplay between attention deficit hyperactivity disorder (ADHD) symptoms and emotional functioning in relation to peer problems. Parent ratings of ADHD symptoms and regulation/reactivity with regard to four emotions (anger, sadness, fear, and happiness/exuberance) at age six were investigated in relation to sociometric peer nominations 3years later in a non-clinical sample (n=91). Reactivity and regulation were only modestly correlated, and these two aspects of emotional functioning did not show the same relation to peer problems. The main finding was that, it was primarily children with high levels of ADHD symptoms in combination with either high dysregulation or low reactivity with regard to happiness/exuberance who received many negative peer nominations. In addition, high levels of ADHD symptoms in combination with high reactivity with regard to anger were associated with nominations of physical aggression. The modest relation between reactivity and regulation emphasizes the importance of separating these two constructs. The fact that it was primarily happiness/exuberance, as opposed to negative emotions, that was associated with negative peer nominations suggests that future studies are needed to clarify the role of specific emotions in relation to the functional impairments associated with ADHD symptoms. Highlights The present study aimed to investigate the interplay between ADHD symptoms and emotional functioning in relation to peer problems using a longitudinal design (age 6-9 years). Ratings of ADHD symptoms and emotional functioning were investigated in relation to sociometric peer nominations and results showed that it was primarily children with high levels of ADHD symptoms in combination with either high dysregulation or low reactivity with regard to happiness/exuberance who received many negative peer nominations. The fact that it was primarily happiness/exuberance, as opposed to negative emotions, that was associated with negative peer nominations suggests that future studies are needed to clarify the role of specific emotions in relation to the functional impairments associated with ADHD symptoms.

(författare) Executive functioning deficits in relation to symptoms of ADHD and/or ODD in preschool children 2006 Ingår i: Infant and Child Development. - : Wiley. - 1522-7227 .- 1522-7219. ; 15:5, s. 503-518 Tidskriftsartikel (refereegranskat)abstract The present study investigated the relation between executive functioning and symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) in children aged 4-6. A population-based sample (n=201) was used and laboratory measures of inhibition, working memory and verbal fluency and teacher ratings of disruptive behaviour problems were collected. Both group differences and linear relations were studied and comorbidity was controlled for dimensionally. In both categorical and dimensional analyses, executive functioning was associated with symptoms of ADFID, but not with symptoms of ODD when controlling for comorbidity, and no significant interactive effects of ADHD and ODD symptoms were found. Effect sizes for significant effects were generally in the medium range. Regarding sex differences, the control for comorbid ODD symptoms appeared to affect the relation between ADHD symptoms and executive functioning somewhat more for girls compared with boys. In conclusion, poor executive functioning in preschool appears to be primarily related to symptoms of ADHD, whereas the relation to symptoms of ODD can be attributed to the large overlap between these two disruptive disorders.
23.	Thorell, Lisa B., et al. (författare) Parent-child attachment and executive functioning in relation to ADHD symptoms in middle childhood 2012 Ingår i: Attachment & Human Development. - : Informa UK Limited. - 1461-6734 .- 1469-2988. ; 14:5, s. 517-532 Tidskriftsartikel (refereegranskat)abstract This study investigated attachment representations and executive functioning (i.e., response inhibition and working memory) at age 8 1/2 in relation to ADHD symptoms one year later. Well-validated laboratory measures of both executive functioning and attachment representations were used. Additive, interaction, as well as mediation effects were investigated. The results showed that attachment disorganization and executive functioning were independently related to ADHD symptoms, even when using conduct problems as a covariate. No significant interaction effects were found, and executive functioning was not found to act as a mediator between attachment disorganization and ADHD symptoms. In conclusion, attachment disorganization had a significant effect on ADHD symptoms, independent of both executive functioning and conduct problems, which suggests that the parent-child attachment is a factor that needs to be included if we are to more fully understand the development of ADHD.
24.	Thorell, Lisa B., et al. (författare) The Childhood Executive Functioning Inventory (CHEXI) : A new rating instrument for parents and teachers 2008 Ingår i: Developmental Neuropsychology. - : Informa UK Limited. - 8756-5641 .- 1532-6942. ; 33:4, s. 536-552 Tidskriftsartikel (refereegranskat)abstract Poor executive functioning has been shown to be of central importance in disruptive behavior disorders such as attention deficit hyperactivity disorder (ADHD), and a large number of laboratory measures of executive functioning have been developed. There are, however, few available questionnaires tapping executive functioning and those that exist also include items focused directly on the symptom criteria for ADHD, which makes it difficult to draw conclusions regarding executive functioning per se. In the present study, a new rating instrument, the Childhood Executive Functioning Inventory (CHEXI) was therefore introduced. This instrument was shown to have good test-retest reliability. Using factor analysis, two factors tapping working memory and inhibition emerged using parent ratings and these two factors were replicated using teacher ratings. Modest, yet mostly significant, relations to laboratory measures of working memory and inhibition were found. Ratings on the CHEXI were also found to be significantly related to ADHD symptoms as well as early academic achievement. Interestingly, ratings on the CHEXI and laboratory measures of working memory and inhibition were shown to explain independent variance in ADHD symptoms and academic achievement, which point to the importance of using a multi-assessment strategy when studying executive functioning.
25.	Thorell, Lisa B., et al. (författare) Training and transfer effects of executive functions in preschool children 2009 Ingår i: Developmental Science. - : Wiley. - 1363-755X .- 1467-7687. ; 12:1, s. 106-113 Tidskriftsartikel (refereegranskat)abstract Executive functions, including working memory and inhibition, are of central importance to much of human behavior. Interventions intended to improve executive functions might therefore serve an important purpose. Previous studies show that working memory can be improved by training, but it is unknown if this also holds for inhibition, and whether it is possible to train executive functions in preschoolers. In the present study, preschool children received computerized training of either visuo-spatial working memory or inhibition for 5 weeks. An active control group played commercially available computer games, and a passive control group took part in only pre- and posttesting. Children trained on working memory improved significantly on trained tasks; they showed training effects on non-trained tests of spatial and verbal working memory, as well as transfer effects to attention. Children trained on inhibition showed a significant improvement over time on two out of three trained task paradigms, but no significant improvements relative to the control groups on tasks measuring working memory or attention. In neither of the two interventions were there effects on non-trained inhibitory tasks. The results suggest that working memory training can have significant effects also among preschool children. The finding that inhibition could not be improved by either one of the two training programs might be due to the particular training program used in the present study or possibly indicate that executive functions differ in how easily they can be improved by training, which in turn might relate to differences in their underlying psychological and neural processes.

A further aspiration of the study was to enhance the limited knowledge on how the various stop-signal measures relate to ADHD behaviors in a normal sample. We also wanted to contribute to the theoretical understanding of the various stop-signal measures by examining the relations between the stop-signal measures and performance on tasks reflecting other aspects of response inhibition and execution. Our results showed that the ability to inhibit as well as to execute a motor response as measured by the stop-signal task improved with age during childhood. Of specific interest are the findings suggesting that this task captures the development of motor response inhibition in the late preschool years (age 5 years). Both of the inhibition measures derived from the stop-signal task (i.e., SSRT and probability of inhibition) related significantly to teacher ratings of inattention as well as to performance on tasks tapping other aspects of inhibition. The data provided by this study have thus contributed to the scarce knowledge on early development of motor response inhibition, as well as suggested that the stop-signal task may be a valuable tool for capturing deficient motor response inhibition in ADHD behaviors in normal samples.

(författare) ADHD symptoms and Executive Function Impairment : Early Predictors of Later Behavioral Problems 2008 Ingår i: Developmental Neuropsychology. - : Informa UK Limited. - 8756-5641 .- 1532-6942. ; 33:2, s. 160-178 Tidskriftsartikel (refereegranskat)abstract This longitudinal study investigated ADHD symptoms and EF impairments in terms of continuity and cross-domain associations, as well as their predictive relations to a range of socioemotional problem behaviors. We applied a factorial ANOVA design to study additive and interactive effects in a sample of non-clinical preschool children (N = 87) and complemented these analyses with group contrasts. The results showed that early ADHD symptoms and EF impairments acted as predictors of continuing problems within each domain. However, it was only ADHD symptoms that predicted other aspects of socioemotional functioning such as dysfunctional emotional regulation and lower levels of social competence. There was no indication of interactive effects on any measure. In conclusion, our results showed that both ADHD symptoms and impaired EF act as early predictors of problem behaviors, although it is clear that predictions based on ADHD symptoms encompass a wider range of problems in early school age children.

A community-based sample of school children (n∈=∈182; the higher end of the ADHD symptom range was oversampled) completed neuropsychological tasks designed to measure executive function (EF), state regulation and delay aversion. Behavioral symptoms were measured through parental and teacher ratings of the DSM-IV criteria for ADHD and Oppositional Defiant Disorder (ODD). Both categorical and dimensional analyses were used to acquire a deeper understanding of ADHD. The results supported the notion that EF and state regulation constitute independent pathways to ADHD, primarily to symptoms of inattention. In addition, the present study points to the importance of viewing ADHD as a heterogeneous condition also with regard to the differential impact of neuropsychological functioning and comorbidity on different ADHD symptom groups and the two ADHD symptom domains.
