- Relational victimization typically emerges first during the elementary school period, and has been associated with increased levels of internalizing symptoms in children. Individual differences in autonomic nervous system functioning have been suggested as a potential factor linking social stressors and internalizing symptoms. The aim of this study was therefore to examine whether heart rate and heart rate variability mediated the association between relational victimization and internalizing symptoms in 373 mainstream elementary school children. Children were assessed in 2015 (T 0 ; Grades 3-5, M age = 9.78 years, 51% boys) and reassessed in 2016 (T 1 ). Heart rate and heart rate variability were assessed during a regular school day at T 1 . A multi-informant (teacher and peer report) cross-time measure of relational victimization, and a multi-informant (self- and teacher report) measure of internalizing problems at T 1 was used. Results showed that heart rate variability, but not heart rate, mediated the association between relational victimization and internalizing symptoms. This study provides tentative support that in children from a general population sample, a psychobiological factor may mediate the association of relational victimization with internalizing symptoms.

- Social anxiety is one of the most commonly reported mental health problems among adolescents, and it has been suggested that parenting style influences an adolescent's level of anxiety. A context-dependent effect of oxytocin on human social behavior has been proposed; however, research on the oxytocin gene (OXT) has mostly been reported without considering contextual factors. This study investigated the interactions between parenting style and polymorphic variations in the OXT gene in association with social anxiety symptoms in a community sample of adolescents (n = 1,359). Two single nucleotide polymorphisms linked to OXT, rs4813625 and rs2770378, were genotyped. Social anxiety and perceived parenting style were assessed by behavioral questionnaires. In interaction models adjusted for sex, significant interaction effects with parenting style were observed for both variants in relation to social anxiety. The nature of the interactions was in line with the differential susceptibility framework for rs4813625, whereas for rs2770378 the results indicated a diathesis–stress type of interaction. The findings may be interpreted from the perspective of the social salience hypothesis of oxytocin, with rs4813625 affecting social anxiety levels along a perceived unsafe–safe social context dimension.

Tidskriftsartikel (refereegranskat)abstract
- Prior to the COVID-19 pandemic, adolescents (N = 1,330; Mages = 15 and 16; 50% female), mothers, and fathers from nine countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, United States) reported on adolescents' internalizing and externalizing problems, adolescents completed a lab-based task to assess tendency for risk-taking, and adolescents reported on their well-being. During the pandemic, participants (Mage = 20) reported on changes in their internalizing, externalizing, and substance use compared to before the pandemic. Across countries, adolescents' internalizing problems pre-pandemic predicted increased internalizing during the pandemic, and poorer well-being pre-pandemic predicted increased externalizing and substance use during the pandemic. Other relations varied across countries, and some were moderated by confidence in the government's handling of the pandemic, gender, and parents' education.

Tidskriftsartikel (refereegranskat)abstract
- Sports participation, physical activity, and friendship quality are theorized to have protective effects on the developmental emergence of substance use and self-harm behavior in adolescence, but existing research has been mixed. This ambiguity could reflect, in part, the potential for confounding of observed associations by genetic and environmental factors, which previous research has been unable to rigorously rule out. We used data from the prospective, population-based Child and Adolescent Twin Study in Sweden (n = 18,234 born 1994-2001) and applied a co-twin control design to account for potential genetic and environmental confounding of sports participation, physical activity, and friendship quality (assessed at age 15) as presumed protective factors for adolescent substance use and self-harm behavior (assessed at age 18). While confidence intervals widened to include the null in numerous co-twin control analyses adjusting for childhood psychopathology, parent-reported sports participation and twin-reported positive friendship quality were associated with increased odds of alcohol problems and nicotine use. However, parent-reported sports participation, twin-reported physical activity, and twin-reported friendship quality were associated with decreased odds of self-harm behavior. The findings provide a more nuanced understanding of the risks and benefits of putative protective factors for risky behaviors that emerge during adolescence.

- While neurodevelopmental disorders (NDDs) are highly heritable, several environmental risk factors have also been suggested. However, the role of familial confounding is unclear. To shed more light on this, we reviewed the evidence from twin and sibling studies. A systematic review was performed on case control and cohort studies including a twin or sibling within-pair comparison of neurodevelopmental outcomes, with environmental exposures until the sixth birthday. From 7,315 screened abstracts, 140 eligible articles were identified. After adjustment for familial confounding advanced paternal age, low birth weight, birth defects, and perinatal hypoxia and respiratory stress were associated with autism spectrum disorder (ASD), and low birth weight, gestational age and family income were associated with attention-deficit/hyperactivity disorder (ADHD), categorically and dimensionally. Several previously suspected factors, including pregnancy-related factors, were deemed due to familial confounding. Most studies were conducted in North America and Scandinavia, pointing to a global research bias. Moreover, most studies focused on ASD and ADHD. This genetically informed review showed evidence for a range of environmental factors of potential casual significance in NDDs, but also points to a critical need of more genetically informed studies of good quality in the quest of the environmental causes of NDDs.

Tidskriftsartikel (refereegranskat)abstract
- Attention-deficit/hyperactivity disorder (ADHD) symptoms are associated with myriad adverse outcomes, including interpersonal difficulties, but factors that moderate the developmental course and functional impact of ADHD over time are not well understood. The present study evaluated developmental contributions of the triarchic neurobehavioral traits (boldness, meanness, and disinhibition) to ADHD symptomatology and its subdimensions from adolescence to young adulthood. Participants were twins and triplets assessed at ages 14, 17, and 19 (initial N = 1,185, 51.2% female). Path analyses using negative binomial regression revealed that boldness at age 14 was associated with more ADHD symptoms cross-sectionally (especially hyperactivity/impulsivity), but fewer symptoms (especially inattention) at age 19 in the prospective analysis. Notably, inclusion of interpersonal problems at ages 14 and 17 as covariates reduced the latter effect to nonsignificant. Disinhibition concurrently and prospectively predicted higher levels of ADHD symptoms, including both subdimensions, and the prospective effects were partially mediated by greater social impairment at age 17. Meanness prospectively (but not concurrently) predicted higher levels of hyperactivity/impulsivity symptoms. Sex moderated certain associations of meanness and disinhibition with ADHD symptoms. These findings highlight how fundamental neurobehavioral traits shape both psychopathology and adaptive outcomes in the developmental course of ADHD.

Tidskriftsartikel (refereegranskat)abstract
- Autism is a developmental disorder with variable severity, occurring at all levels of cognitive ability and having a number of slightly different clinical presentations. It is associated with neuropsychological deficits that occur in other conditions also, but its pattern may be specific to autism. Genetic and environmental early insults to brain development are etiological determinants of the disorder. Brain circuitries important for social, communicative, and integrational purposes have been suggested to be dysfunctional in autism. There could be at least two different pathways to autism, one connected with primary temporofrontal dysfunction (and late prenatal–early postnatal origins) and another linked to primary brain-stem dysfunction (and early prenatal origins). Further study of neurodevelopmental and neuropsychological processes in autism will help elucidate not only the pathological mechanisms involved in the specific syndromes but also the underpinnings of normal brain development.

Young men's behavioral competencies and risk of alcohol use disorder in emerging adulthood : Early protective effects of parental education

Tidskriftsartikel (refereegranskat)abstract
- We investigate how early exposure to parental externalizing behaviors (EB) may contribute to development of alcohol use disorders (AUD) in young adulthood, testing a developmental cascade model focused on competencies in three domains (academic, conduct, and work) in adolescence and emerging adulthood, and examining whether high parental education can buffer negative effects of parental EB and other early risk factors. We use data from 451,054 Swedish-born men included in the national conscript register. Structural equation models showed parental EB was associated with academic and behavioral problems during adolescence, as well as with lower resilience, more criminal behavior, and reduced social integration during emerging adulthood. These pathways led to elevated rates of AUD in emerging and young adulthood. Multiple groups analysis showed most of the indirect pathways from parental EB to AUD were present but buffered by higher parental education, suggesting early life experiences and competencies matter more for young men from lower socioeconomic status (SES) families than from higher SES families. Developmental competencies in school, conduct, and work are important precursors to the development of AUD by young adulthood that are predicted by parental EB. Occupational success may be an overlooked source of resilience for young men from low-SES families.

Tidskriftsartikel (refereegranskat)abstract
- A study was conducted to determine predictors of high risk/delinquent behavior and psychoemotional maladjustment in 1,478 sixth and eighth graders who took part in a survey of high-risk and adaptive behaviors. The first goal was to determine the extent to which two distinct dimensions of alienation, normlessness, and isolation/self-estrangement mediated the emergence of maladjustment in youth exposed to community violence. The second goal was to distinguish between violence witnessing and violence victimization, and determine whether these subtypes of violence exposure may differentially affect the proposed mediational factors. The results indicated that normlessness partially mediated the relationship between violence exposure and high-risk/delinquent behavior and between violence exposure and psychoemotional maladjustment. Isolation/self-estrangement partially mediated the relation between violence exposure and psychoemotional maladjustment. Although witnessing of, and victimization by, violence were both significant predictors of normlessness, only violent victimization was significantly linked to isolation/self-estrangement. These results elucidate the mechanisms by which community violence exposure may exert negative influences on youth and suggest that there are distinct patterns of risk associated with different forms of exposure.
