- Although previous research has identified contemporaneous associations between cognitive deficits and symptom phenotypes in Attention Deficit/Hyperactivity Disorder, no studies have as yet attempted to identify direction of effect. The present study used cross-lagged path modeling to examine competing hypotheses about longitudinal associations between rapid naming speed and symptoms of inattention in children. 1,506 school-age twins from Australia and the U.S. were tested for inattention, hyperactivity/impulsivity, and rapid naming speed at three and four time points, respectively. Symptom severity of inattention from Kindergarten to fourth grade is consistently predicted by previous rapid naming, over and above auto-regressive and correlational associations in the model. Likewise, inattention symptoms have a small but significant predictive effect on subsequent rapid naming. The findings support a reciprocal relationship between naming speed and ADHD inattentive symptoms.

- 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.

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.

Tidskriftsartikel (refereegranskat)abstract
- Research has documented that children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are at increased risk of substance use problems. Few studies, however, have focused on early-onset substance use. This study therefore investigated how the two symptom dimensions of ADHD (hyperactivity/impulsivity and inattention) are associated with early-onset substance use, the role of persistent ADHD for the association, and to what extent the association is influenced by genetic and environmental factors. Twins (1,480 pairs) in the Swedish Twin Study of Child and Adolescent Development were followed from childhood to adolescence. ADHD symptoms were measured at age 8-9 and age 13-14 via parent-report, whereas substance use was assessed at age 13-14 via self-report. Results revealed that hyperactive/impulsive symptoms predicted early-onset "sometimes" tobacco use (adjusted odds ratios, 1.12, for one symptom count), controlling for inattentive symptoms and conduct problem behaviors. There is no independent effect of inattentive symptoms on early-onset substance use. Children with persistent hyperactivity/impulsivity (defined as scoring above the 75th percentile at both time points) had a pronounced risk of both early-onset tobacco and alcohol use (adjusted odds ratios from 1.86 to 3.35, compared to the reference group). The associations between hyperactivity/impulsivity and early-onset substance use were primarily influenced by genetic factors. Our results indicated that hyperactivity/impulsivity, but not inattention, is an important early predictor for early-onset substance use, and a shared genetic susceptibility is suggested to explain this association.

- Hyperactivity, impulsivity, and attention problems(HIA) in children and adolescents are stressful for parents. In this study, we used theories of parents’ perceived power and attributions for youths’ behaviors to develop a model to understand parents’ reactions to their youths’ HIA. We followed 706 youths (376 boys and 330 girls, aged 10–12 years at T1) and their parents in a community-based project over 5 years. Measures of youths’ HIA, youths’ unresponsiveness to correction, parents’ feelings of powerlessness, parental monitoring, and parents’ negative behaviors toward their youths, were used. HIA in youths predicted increases in parents’ perceptions that their youths were unresponsive to correction, which in turn prompted parents to feel more powerless over time. Further, parents’ feelings of powerlessness were associated with increases in negative parenting behaviors over time. These results indicate a movement to more negative parenting practices over time as a result of youths’ HIA.

Reading Comprehension in Children with ADHD: Cognitive Underpinnings of the Centrality Deficit
- 2013

Tidskriftsartikel (refereegranskat)abstract
- We examined reading comprehension in children with ADHD by assessing their ability to build a coherent mental representation that allows them to recall central and peripheral information. We compared children with ADHD (mean age 9.78) to word reading-matched controls (mean age 9.89) on their ability to retell a passage. We found that even though children with ADHD recalled more central than peripheral information, they showed their greatest deficit, relative to controls, on central information-a centrality deficit (Miller and Keenan, Annals of Dyslexia 59:99-113, 2009). We explored the cognitive underpinnings of this deficit using regressions to compare how well cognitive factors (working memory, inhibition, processing speed, and IQ) predicted the ability to recall central information, after controlling for word reading ability, and whether these cognitive factors interacted with ADHD symptoms. Working memory accounted for the most unique variance. Although previous evidence for reading comprehension difficulties in children with ADHD have been mixed, this study suggests that even when word reading ability is controlled, children with ADHD have difficulty building a coherent mental representation, and this difficulty is likely related to deficits in working memory.

Tidskriftsartikel (refereegranskat)abstract
- This study examined the extent to which sixth grade peer status could predict anxiety and/or depression in 5,242 women and 5,004 men who were born in 1953 and whose hospital records were followed up from 1973–2003. The data used was the Stockholm Birth Cohort Study. While no association could be established for men, results indicated that women who held low peer status positions in childhood were at a considerably higher risk of anxiety and/or depression later in life compared to women in average status positions. Women who held popular positions during childhood did not differ significantly from their average counterparts. These findings persisted after adjusting for family- and child-related problem-load, perceived security at school, family constellation, socioeconomic status as well as the child’s cognitive ability, ninth grade school marks and continuance to upper secondary school.

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.

Xenophobia and tolerance toward immigrants in adolescence : cross-influence processes within friendships
- 2013

Tidskriftsartikel (refereegranskat)abstract
- To what extent do adolescents and their friends socialize each others' attitudes toward immigrants? Can friends' positive attitudes toward immigrants counter adolescents' negative attitudes toward immigrants, and do friends' negative attitudes decrease adolescents' positive attitudes? These questions were examined by following a large (N = 1,472) friendship network of adolescents (49.2 % girls; M (age) = 13.31 at first measurement) across three annual measurements. Selection and influence processes regarding tolerance and xenophobia were distinguished with longitudinal social network analyses, controlling for effects of age, gender, and immigrant background. Findings showed that friends' tolerance predicted increases in adolescents' tolerance and friends' xenophobia predicted increases in adolescents' xenophobia. Moreover, friends' tolerance predicted a lower likelihood of adolescents' xenophobia increasing. The current results suggest that interventions should distinguish between tolerance and xenophobia, as these appear to represent two separate dimensions that are each influenced in specific ways by friends' tolerance and xenophobia.
