- One of the most comprehensive measures of mindfulness is the Five Facet Mindfulness Questionnaire (FFMQ) with five factors-Observing, Describing, Acting with awareness, Non-judging, and Non-reactivity. Hierarchical confirmatory factor analyses, however, have suggested that only four of the FFMQ factors (i.e. all except Observing) were components of "an overall mindfulness construct"-which is puzzling because Observing represents a core aspect of all definitions of mindfulness. The purpose of the present study was to approach this problem by a person-oriented approach, focusing on patterns on the FFMQ scales, rather than linear associations between them. Data on the FFMQ were collected on 817 individuals. Cluster analysis according to the LICUR procedure was used to group these participants in 13 clusters, according to their profiles of scores on the five FFMQ scales. Of the participants, 325 were categorized as meditators and 317 as non-meditators. To test hypotheses about the relation between Observing and mindfulness (which we assumed should be higher among meditators), the meditators/non-meditators categorization was cross-tabulated with the FFMQ clusters. The results showed that all clusters in which meditators were over-represented had high scores on Observing, and all clusters in which meditators were under-represented had low scores on Observing-which supports the hypothesis that mindfulness is related to high levels of Observing. The relationship between Observing and Non-judging, however, was found to be more complex than expected. The results are discussed in terms of mindfulness seen as a multidimensional skill, which may develop differently in various subgroups of individuals.

Tidskriftsartikel (refereegranskat)abstract
- The effects of driver sleepiness are often quantified as deteriorated driving performance, increased blink durations and high levels of subjective sleepiness. Driver sleepiness has also been associated with increasing levels of electroencephalogram (EEG) power, especially in the alpha range. The present exploratory study investigated a new measure of driver sleepiness, the EEG fixation-related lambda response. Thirty young male drivers (23.6 +/- 1.7 years old) participated in a driving simulator experiment in which they drove on rural and suburban roads in simulated daylight versus darkness during both the daytime (full sleep) and night-time (sleep deprived). The results show lower lambda responses during night driving and with longer time on task, indicating that sleep deprivation and time on task cause a general decrement in cortical responsiveness to incoming visual stimuli. Levels of subjective sleepiness and line crossings were higher under the same conditions. Furthermore, results of a linear mixed-effects model showed that low lambda responses are associated with high subjective sleepiness and more line crossings. We suggest that the fixation-related lambda response can be used to investigate driving impairment induced by sleep deprivation while driving and that, after further refinement, it may be useful as an objective measure of driver sleepiness.

Higher- and lower-order personality traits and cluster subtypes in social anxiety disorder
- 2020
-
Ingår i: PLOS ONE. - : PUBLIC LIBRARY SCIENCE. - 1932-6203. ; 15:4
-
Tidskriftsartikel (refereegranskat)abstract
- Social anxiety disorder (SAD) can come in different forms, presenting problems for diagnostic classification. Here, we examined personality traits in a large sample of patients (N = 265) diagnosed with SAD in comparison to healthy controls (N = 164) by use of the Revised NEO Personality Inventory (NEO-PI-R) and Karolinska Scales of Personality (KSP). In addition, we identified subtypes of SAD based on cluster analysis of the NEO-PI-R Big Five personality dimensions. Significant group differences in personality traits between patients and controls were noted on all Big Five dimensions except agreeableness. Group differences were further noted on most lower-order facets of NEO-PI-R, and nearly all KSP variables. A logistic regression analysis showed, however, that only neuroticism and extraversion remained significant independent predictors of patient/control group when controlling for the effects of the other Big Five dimensions. Also, only neuroticism and extraversion yielded large effect sizes when SAD patients were compared to Swedish normative data for the NEO-PI-R. A two-step cluster analysis resulted in three separate clusters labelled Prototypical (33%), Introvert-Conscientious (29%), and Instable-Open (38%) SAD. Individuals in the Prototypical cluster deviated most on the Big Five dimensions and they were at the most severe end in profile analyses of social anxiety, self-rated fear during public speaking, trait anxiety, and anxiety-related KSP variables. While additional studies are needed to determine if personality subtypes in SAD differ in etiological and treatment-related factors, the present results demonstrate considerable personality heterogeneity in socially anxious individuals, further underscoring that SAD is a multidimensional disorder.

The 18-item Swedish version of Ryff's psychological wellbeing scale: psychometric properties based on classical test theory and item response theory
- 2023

Tidskriftsartikel (refereegranskat)abstract
- BackgroundPsychological wellbeing is conceptualized as the full engagement and optimal performance in existential challenges of life. Our understanding of psychological wellbeing is important for us humans to survive, adapt, and thrive during the challenges of the 21st century. Hence, the measurement of psychological wellbeing is one cornerstone for the identification and treatment of both mental illness and health promotion. In this context, Ryff operationalized psychological wellbeing as a six-dimensional model of human characteristics: self-acceptance, positive relations with others, environmental mastery, personal growth, autonomy, and purpose in life. Ryff's Psychological Wellbeing Scale has been developed and translated into different versions. Here, we examine and describe the psychometric properties of the 18-item Swedish version of Ryff's Psychological Wellbeing Scale using both Classical Test Theory (CTT) and Item Response Theory (IRT).MethodsThe data used in the present study was earlier published elsewhere and consists of 768 participants (279 women and 489 men). In addition to the 18-item version of the scale, participants answered the Temporal Satisfaction with Life Scale, the Positive Affect Negative Affect Schedule, and the Background and Health Questionnaire. We examined, the 18-item version's factor structure using different models and its relationship with subjective wellbeing, sociodemographic factors (e.g., education level, gender, age), lifestyle habits (i.e., smoking, frequency of doing exercise, and exercise intensity), and health issues (i.e., pain and sleeping problems). We also analyzed measurement invariance with regard to gender. Moreover, as an addition to the existing literature, we analyzed the properties of the 18 items using Graded Response Model (GRM).ResultsAlthough the original six-factor structure showed a good fit, both CTT and IRT indicated that a five-factor model, without the purpose in life subscale, provided a better fit. The results supported the internal consistency and concurrent validity of the 18-item Swedish version. Moreover, invariance testing showed similar measurement precision by the scale across gender. Finally, we found several items, especially the purpose in life's item "I live life one day at a time and do not really think about the future," that might need revision or modification in order to improve measurement.ConclusionA five-factor solution is a valid and reliable measure for the assessment of psychological wellbeing in the general Swedish population. With some modifications, the scale might achieve enough accuracy to measure the more appropriate and correct six-dimensional theoretical framework as detailed by Ryff. Fortunately, Ryff's original version contains 20 items per subscale and should therefore act as a perfect pool of items in this endeavor.

Forskningsöversikt (refereegranskat)abstract
- IMPORTANCE: Personalized treatment choices would increase the effectiveness of internet-based cognitive behavioral therapy (iCBT) for depression to the extent that patients differ in interventions that better suit them.OBJECTIVE: To provide personalized estimates of short-term and long-term relative efficacy of guided and unguided iCBT for depression using patient-level information.DATA SOURCES: We searched PubMed, Embase, PsycInfo, and Cochrane Library to identify randomized clinical trials (RCTs) published up to January 1, 2019.STUDY SELECTION: Eligible RCTs were those comparing guided or unguided iCBT against each other or against any control intervention in individuals with depression. Available individual patient data (IPD) was collected from all eligible studies. Depression symptom severity was assessed after treatment, 6 months, and 12 months after randomization.DATA EXTRACTION AND SYNTHESIS: We conducted a systematic review and IPD network meta-analysis and estimated relative treatment effect sizes across different patient characteristics through IPD network meta-regression.MAIN OUTCOMES AND MEASURES: Patient Health Questionnaire-9 (PHQ-9) scores.RESULTS: Of 42 eligible RCTs, 39 studies comprising 9751 participants with depression contributed IPD to the IPD network meta-analysis, of which 8107 IPD were synthesized. Overall, both guided and unguided iCBT were associated with more effectiveness as measured by PHQ-9 scores than control treatments over the short term and the long term. Guided iCBT was associated with more effectiveness than unguided iCBT (mean difference [MD] in posttreatment PHQ-9 scores, -0.8; 95% CI, -1.4 to -0.2), but we found no evidence of a difference at 6 or 12 months following randomization. Baseline depression was found to be the most important modifier of the relative association for efficacy of guided vs unguided iCBT. Differences between unguided and guided iCBT in people with baseline symptoms of subthreshold depression (PHQ-9 scores 5-9) were small, while guided iCBT was associated with overall better outcomes in patients with baseline PHQ-9 greater than 9.CONCLUSIONS AND RELEVANCE: In this network meta-analysis with IPD, guided iCBT was associated with more effectiveness than unguided iCBT for individuals with depression, benefits were more substantial in individuals with moderate to severe depression. Unguided iCBT was associated with similar effectiveness among individuals with symptoms of mild/subthreshold depression. Personalized treatment selection is entirely possible and necessary to ensure the best allocation of treatment resources for depression.

Validation of the Internet-Administered Quality of Life Inventory (QOLI) in Different Psychiatric Conditions
- 2013

Tidskriftsartikel (refereegranskat)abstract
- The Quality of Life Inventory (QOLI) is an established rating scale of self-perceived quality of life across 16 domains. Norms for different psychiatric conditions when rated via the Internet, responsiveness to change following treatment, and the clinical impact of importance-weighting items have yet to be examined. To investigate these unanswered questions, important for the continued and expanded use of the QOLI, we compiled archival screening and post-treatment data from 20 studies featuring Internet-delivered psychological interventions for seven different psychiatric conditions and an undergraduate sample, totalling over 4000 participants. Disorder-specific norms were indicated by between-group analyses and are reported here, item-by-item. The QOLI showed adequate responsiveness to change and construct validity. Discrepancies were found when conducting between-group analyses with and without weighted items (more significant differences when items were not weighted) on both the screening and post-treatment data, suggesting that weighting is a procedure that is likely to have an impact when analysing QOLI results. Limitations and the needs for future research are discussed.

Exploring reflexive methodology as a pluralist approach to enhance mixed methods research on coping and livability among LGBTQ people in Sweden
- 2024
-
Ingår i: Qualitative Research in Psychology. - : Routledge. - 1478-0887 .- 1478-0895. ; 21:3, s. 328-356

Tidskriftsartikel (refereegranskat)abstract
- The article explores the use of reflexive methodology to enhance mixed methods queer psychological research in Sweden, by analysing data from a qualitative research project on how LGBTQ people cope with minority stress from four epistemological perspectives. A descriptive, hermeneutically and phenomenologically inspired analysis showed that coping should be understood from temporal perspective, where ‘microcoping’ covers strategies used in specific here and now-situations, and ‘macrocoping’ addresses general strategies used over time. We suggest that this differentiation is explored in further research. The analysis then included a theoretically driven perspective using feminist theories and discursive perspectives. Three themes resulted describing different types of constant ongoing work, ‘existential’, ‘relational’ and ‘reflexive’, that participants utilized to carve out a livable existence in the world. We suggest that reflexive methodology can help produce results that can be useful in a local as well as an international context and in relation to different audiences.

Social interaction and gender as factors affecting the trajectories of children's engagement and hyperactive behaviour in preschool
- 2021
-
Ingår i: British Journal of Educational Psychology. - : John Wiley & Sons. - 0007-0998 .- 2044-8279. ; 91:2, s. 617-637

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Social interactions in preschool and a child's gender are, in cross-sectional studies, related to the child's overall levels of hyperactive behaviour and engagement in preschool activities. However, whether social interaction and gender can predict children's engagement and hyperactivity is not thoroughly investigated. This study aims to investigate the longitudinal influence of gender, child-to-child interaction, and teacher responsiveness on the association between trajectories of children's levels of core engagement and hyperactive behaviour. It was hypothesized that peer-to-child interaction and teacher responsiveness in preschool settings are related to positive change in engagement among children with hyperactive behaviour, especially for boys.Sample and methods: Swedish preschool staff completed questionnaires assessing the variables of interest for children aged 1–5 (N = 203). Data were collected on three occasions over a two-year period. Latent growth curve (LGC) models were used to explore whether teacher responsiveness, peer-to-child interaction, and gender predict trajectories of engagement and hyperactivity.Results: The results revealed that high levels of hyperactivity were associated with lower levels of engagement on the first occasion. Positive peer-to-child interactions and responsive teachers were significant predictors of an increased level of engagement and decreased level of hyperactive behaviour, especially for boys.Conclusions: The findings underscore the need to improve social interactions, especially peer-to-child interactions, to improve engagement in children with hyperactive behaviour, especially boys. Implications for practices and research are discussed.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The aim of this research forum article was to describe a feasible web-based solution for improving the quality of life of persons with hearing problems, such as hearing loss or tinnitus. The online platform was developed at the Department of Behavioural Sciences and Learning at Linköping University, Sweden, and has been running for a number of years and used in numerous studies and treatments. Method: The security aspects of the platform as well as the process flow for running a study or treatment are described, focusing primarily on the technical and practical considerations. Also presented are the design characteristics and the main features and functions available in the platform. Results: We point out the many advantages of running Internet-assisted intervention treatments, the challenges that we have faced, and some intended developments. Many of our research colleagues, both from Sweden and other countries, have already implemented or intend to implement their own studies on this platform. Conclusions: Audiological rehabilitation can be delivered via the Internet using a stable online platform. Security and usability are important factors to have in mind for the design as well as adaptability to the patients. A next development step is to implement and test blended treatments using video conferencing inside the platform.

Bridging the Gap Between Hearing Screening and Successful Rehabilitation : Research Protocol of a Randomized Controlled Trial of Motivational Interviewing via Internet
- 2015
-

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Studies point to low help-seeking after a failed hearing screening. This research forum article presents the research protocol for a randomized controlled trial of motivational interviewing via the Internet to promote help-seeking in people who have failed an online hearing screening. Method: Adults who fail a Swedish online hearing screening, including a speech-in-noise recognition test, will be randomized to either an intervention group (participating in motivational interviewing) or an active control group (reading a book on history of hearing aids). Both of the conditions will be delivered via the Internet. The primary outcome is experience with seeking health care and using hearing aids 9 months after the intervention. Secondary outcomes are changes in before and after measures of self-reported hearing difficulties, anxiety, depression, and quality of life. Stages of change and self-efficacy in hearing help-seeking are measured immediately after intervention and at a 9-month follow-up for the purpose of mediation analysis. Results: The results of this randomized controlled trial may help bridge the gap between hearing screening and successful hearing rehabilitation. Conclusion: Although no large instantaneous benefits are expected, a slow change toward healthy behaviors—seeking health care and using hearing aids—would shed light on how to use the Internet to assist people with hearing impairment.
