- Objectives: The purpose of this study was to assess the reliability and validity of Swedish translations of the Beliefs about Medicines Questionnaire-Specific (BMQ-Specific) and Brief Illness Perception Questionnaire (B-IPQ) for use in adolescents with ADHD. Methods: Forward and backward translations of the BMQ-Specific and B-IPQ scales to Swedish were conducted and reviewed by adolescents with ADHD and professionals. The validity and reliability of both questionnaires were investigated in a cross-sectional study of 101 adolescents (13-17 years) on a long-term prescription of ADHD medication recruited from two child and adolescent psychiatric outpatient clinics in Sweden. Results: Regarding the BMQ-Specific, principal component analysis (PCA) loadings confirmed the previously defined components of Specific-Necessity and Specific-Concern. The PCA for B-IPQ revealed two components, the first one, B-IPQ Consequences, captured questions regarding perceptions of the implication of having ADHD (items 1, 2, 5, 6 and 8) and the second one, B-IPQ-Control, the perceptions of the capability to manage the ADHD disorder (items 3, 4 and 7). The Cronbach alpha coefficients for BMQ-Specific-Necessity scale was α = 0.80, for BMQ-Specific-Concern scale α = 0.75, B-IPQ Consequences α = 0.74 and for B-IPQ-Control α = 0.44. Conclusions: The present results prove the Swedish translation of BMQ-Specific and B-IPQ to be valid and reliable for utilization in adolescents with ADHD. The PCA confirmed the original components for BMQ-Specific and the recent findings of two main B-IPQ components describing emotional and cognitive implications versus the capability for self-care maintenance of ADHD.

Environmental and Genetic Influences in Attention Deficit Hyperactivity Disorder (ADHD) and its Comorbidities
- 2016

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Research in past decades has demonstrated the persistence of attention deficit hyperactivity disorder (ADHD) into adulthood, but many questions regarding prevalence, causes, and comorbidities of ADHD in adults remain to be investigated. Previous research focusing on childhood ADHD identified high heritability. Genetic and environmental influences on ADHD symptoms in adults and their association with comorbid conditions are not fully understood.The overall aim of this thesis was to study adult ADHD symptoms in the population and investigate associations with substance use disorders (SUD) and binge eating. In all four papers, we used population-based self-report data from twins aged 20–46 years from the Swedish Twin Registry. We used twin methods to explore the role of genetic and environmental factors underlying ADHD symptoms and their comorbidities.Study I examined the phenotypic association between ADHD and various forms of SUD. ADHD in adults was strongly associated with alcohol abuse and alcohol dependence, illicit drug use and regular nicotine use, with no differences between ADHD subtypes and no apparent substance preference. In Studies II and IV, we used bivariate twin models to examine the role of genetic and environmental factors in the association of adult ADHD symptoms with alcohol dependence (II) and with binge eating (IV). For ADHD symptoms and alcohol dependence, 64% of the overlap was explained by common genetic factors. The remaining variance was accounted for by environmental factors specific for each twin, with no sex differences for the overlap. Similarly, 91% of the association between ADHD symptoms and binge-eating behaviour was explained by common genetic factors. In Study III, using a within-twin pair analysis, we demonstrated that although most of the association between adult ADHD symptoms and self-reported childhood maltreatment (an environmental risk factor for ADHD) was explained by familial (genetic and environmental) confounding, our results were also consistent with a causal interpretation.In conclusion, adult ADHD symptoms are associated with SUD and binge-eating behaviour. We replicated findings from adolescent studies regarding shared genetic risk factors for alcohol dependence and ADHD symptoms in adults. For binge eating, we showed for the first time that shared genetic factors mainly explained the association with ADHD symptoms. Alterations in mesolimbic reward processing as well as the frontal, executive and inhibitory systems have been described for ADHD, alcohol dependence and binge-eating behaviour, possibly suggesting common genetic and neurobiological factors for all three conditions. Results that support a causal hypothesis regarding the association between childhood maltreatment and ADHD symptoms in adults need follow-up in longitudinal clinical samples that can examine neurobiological underpinnings of environmental effects. Clinically, the results of this thesis support that ADHD in adults be considered and addressed in adults with SUD or binge-eating behaviour. Given the common genetic risk factors and the role of the early childhood environment, family interventions should be considered for these populations.

Forskningsöversikt (refereegranskat)abstract
- Background: Practitioners and decision makers in the medical and insurance systems need knowledge on the relationship between work exposures and burnout. Many burnout studies -original as well as reviews-restricted their analyses to emotional exhaustion or did not report results on cynicism, personal accomplishment or global burnout. To meet this need we carried out this review and meta-analyses with the aim to provide systematically graded evidence for associations between working conditions and near-future development of burnout symptoms. Methods: A wide range of work exposure factors was screened. Inclusion criteria were: 1) Study performed in Europe, North America, Australia and New Zealand 1990-2013. 2) Prospective or comparable case control design. 3) Assessments of exposure (work) and outcome at baseline and at least once again during follow up 1-5 years later. Twenty-five articles met the predefined relevance and quality criteria. The GRADE-system with its 4-grade evidence scale was used. Results: Most of the 25 studies focused emotional exhaustion, fewer cynicism and still fewer personal accomplishment. Moderately strong evidence (grade 3) was concluded for the association between job control and reduced emotional exhaustion and between low workplace support and increased emotional exhaustion. Limited evidence (grade 2) was found for the associations between workplace justice, demands, high work load, low reward, low supervisor support, low co-worker support, job insecurity and change in emotional exhaustion. Cynicism was associated with most of these work factors. Reduced personal accomplishment was only associated with low reward. There were few prospective studies with sufficient quality on adverse chemical, biological and physical factors and burnout. Conclusion: While high levels of job support and workplace justice were protective for emotional exhaustion, high demands, low job control, high work load, low reward and job insecurity increased the risk for developing exhaustion. Our approach with a wide range of work exposure factors analysed in relation to the separate dimensions of burnout expanded the knowledge of associations, evidence as well as research needs. The potential of organizational interventions is illustrated by the findings that burnout symptoms are strongly influenced by structural factors such as job demands, support and the possibility to exert control.

- 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.

- Adherence to attention deficit hyperactivity disorder (ADHD) treatment is important because, when untreated, it may have serious consequences with lifelong effects. In the case of adolescents on long-term medicine prescription, more knowledge is needed regarding adherence and factors influencing adherence, which was the purpose of this study. Adolescents (n = 101) on ADHD medication ≥6 months were administrated questionnaires at amonitoring appointment: Medication Adherence Report Scale (MARS), beliefs about medicines (BMQ) and the Brief Illness Perception Questionnaire (B-IPQ). Adherencewas high, the mean value was 88% of the maximum MARS score, and correlated positively with the "BMQ necessity-concerns differential" but negatively with "BMQ concerns"and "BMQ-side effects". Adolescents with more belief in the necessity of the medication, less concerns and less experience of side effects tended to be more adherent to medication prescription ("intentional non-adherence"),while "unintentional non-adherence" (forgetfulness) was associated with how much they perceived that their ADHD affected their lives. In a multiple regression model, the variance of MARS total (R2 = 0.21) and “intentional nonadherence” (R2 = 0.24) was explained by the “BMQ-necessity–concern differential” and “BMQ-experienced side effects”. The variance of “unintentional non-adherence” (R2 = 0.12) was explained by the “BMQ-necessity–concern differential” and “B-IPQ-consequences of ADHD”. In conclusion, adolescents on long-term medication reported good adherence, mainly influenced by more beliefs in the necessity versus concerns of the medications, less experienced side effects and more perceived consequences of ADHD. BMQ could be useful to identify risks of low adherence, which should be counteracted by partially gender-specific interventions.
