RESUMEN
Self-control is important for mental and physical health, and personality traits are vital antecedents for self-control. Previous studies suggest that conscientiousness and extraversion enhance self-control, whereas neuroticism hampers it. However, the link between personality and self-control has mostly been studied using a narrow conceptualization of self-control, as the ability to resist impulses, thus excluding initiatory self-control. Also, no studies have examined whether and how personality traits interact with one another to increase, or reduce, self-control. Data were collected on two occasions from 480 military cadets (31.04% female) to examine the relationship between the Big Five personality traits and self-control (general, inhibitory, and initiatory self-control). Furthermore, the study investigated the moderating role of neuroticism, as a trait and as individual facets, on the relationship between the other personality traits and self-control. Although neuroticism correlated negatively with all self-control dimensions, there were unique relations only with general and inhibitory self-control. Extraversion correlated positively with all self-control dimensions but was only uniquely related to initiatory self-control. Conscientiousness correlated positively with all self-control dimensions and this pattern persisted when we assessed the unique effects. Openness to experience and agreeableness correlated positively with general and inhibitory self-control but had no unique effects on any of the self-control dimensions. Neuroticism negatively moderated the relationship between extraversion and both general and inhibitory self-control, and the relationship between conscientiousness and both general and initiatory self-control. The facet-level analysis confirmed the general patterns and provided further detail on which facets of neuroticism were the most influential as moderators. In conclusion, the study highlights the critical role of different types of self-control, and that neuroticism plays a cardinal role for the effects of conscientiousness and extraversion on self-control.

Mental health problems in adolescence are increasing and there is an urgent call for transdiagnostic interventions, as most adolescents experience problems across multiple domains. Research has identified a general psychopathology factor (p) capturing the shared variance across mental health problems. In parallel, there is empirical support for the transdiagnostic nature of emotion regulation. In the current study, we explore the associations between p and emotion regulation strategies to identify which strategies may be promising targets for intervention. Data from the population-based Youth and Mental Health Study (YAMHS) (N = 2,464, mean age 13.7 years, SD 0.6) was used. The fit of different structural models of emotion regulation and psychopathology were compared, and latent factors from the final models were included in multiple regression analyses to explore the associations between p and emotion regulation strategies. A bifactor exploratory structural equation model (B-ESEM) showed best fit for modelling p. For emotion regulation strategies, an ESEM model showed best fit, including Rumination, Reactive Impulsivity, Distraction, Non-Acceptance, Problem Solving, Social Support, and Proactive Behavior. Results showed that a higher score on p was predicted by higher scores on the emotion regulation strategies Rumination (ß = .38, p < .001) and Reactive Impulsivity (ß = .35, p < .001), and lower scores on Problem Solving (ß = -.15, p < .001). The results indicate that Rumination and Reactive Impulsivity have the strongest associations with p and may be promising targets for mental health interventions for adolescents.
RESUMEN
PURPOSE: The Dynamics of Family Conflict (FamC) prospective cohort study was set up to investigate how and why interparental conflicts and family relations develop over time, and in which contexts which types of conflicts and relations are most negative for which children. FamC focuses on the family within a scope spanning macrolevel as well as microlevel processes. PARTICIPANTS: Families were recruited from MoBa (pilot project) and family counselling offices across Norway when parents attended parental counselling, therapy or mandatory mediation in relation to parental relationship dissolution. All families were thus experiencing challenges and/or going through a family transition. Families were eligible for the study if parents had at least one joint child between 0 and 16 years. Both parents and up to five children from the same family could participate. A total of 2871 families were recruited (participation rate wave 1: 78%) and an estimated 55% of parents (based on wave 1 data) were divorced/separated. Additional data were obtained from therapists/mediators at the family counselling offices about the family, and childcare or schoolteachers provided data on the youngest (0-6 years) children. FINDINGS TO DATE: Results show that interparental conflict patterns vary with family constellation. Interparental conflict severity is inversely related to the discrepancy between child-reported and parent-reported child reactions to interparental conflicts, and child-self-reported reactions are higher relative to parent-reported child reactions. Other findings show that family characteristics (eg, the number and age of children in the family and financial difficulties) are predictive of the type of residence arrangement that parents practice. FUTURE PLANS: The cohort is ideally suited for cross-cultural comparisons and further examination of family processes and dynamics including parent repartnering, step-parents and new family members, associations between different family constellations and child adjustment, and fathering, father-child relationship and child adjustment. There are plans for further follow-up data collection.

PURPOSE: Motherhood affects women's mental health, encompassing aspects of both wellbeing and illbeing. This study investigated stability and change in wellbeing (i.e., relationship satisfaction and positive affect) and illbeing (i.e., depressive and anxiety symptoms) from pregnancy to three years postpartum. We further investigated the mutual and dynamic relations between these constructs over time and the role of genetic propensities in their time-invariant stability. DATA AND METHODS: This four-wave longitudinal study included 83,124 women from the Norwegian Mother, Father, and Child Cohort Study (MoBa) linked to the Medical Birth Registry of Norway. Data were collected during pregnancy (30 weeks) and at 6, 18 and 36 months postpartum. Wellbeing and illbeing were based on the Relationship Satisfaction Scale, the Differential Emotions Scale and Hopkins Symptoms Checklist-8. Genetics were measured by the wellbeing spectrum polygenic index. Analyses were based on random intercept cross-lagged panel models using R. RESULTS: All four outcomes showed high stability and were mutually interconnected over time, with abundant cross-lagged predictions. The period of greatest instability was from pregnancy to 6 months postpartum, followed by increasing stability. Prenatal relationship satisfaction played a crucial role in maternal mental health postpartum. Women's genetic propensity to wellbeing contributed to time-invariant stability of all four constructs. CONCLUSION: Understanding the mutual relationship between different aspects of wellbeing and illbeing allows for identifying potential targets for health promotion interventions. Time-invariant stability was partially explained by genetics. Maternal wellbeing and illbeing develop in an interdependent way from pregnancy to 36 months postpartum.
RESUMEN
Epidemiological researchers often examine associations between risk factors and health outcomes in non-experimental designs. Observed associations may be causal or confounded by unmeasured factors. Sibling and co-twin control studies account for familial confounding by comparing exposure levels among siblings (or twins). If the exposure-outcome association is causal, the siblings should also differ regarding the outcome. However, such studies may sometimes introduce more bias than they alleviate. Measurement error in the exposure may bias results and lead to erroneous conclusions that truly causal exposure-outcome associations are confounded by familial factors. The current study used Monte Carlo simulations to examine bias due to measurement error in sibling control models when the observed exposure-outcome association is truly causal. The results showed that decreasing exposure reliability and increasing sibling-correlations in the exposure led to deflated exposure-outcome associations and inflated associations between the family mean of the exposure and the outcome. The risk of falsely concluding that causal associations were confounded was high in many situations. For example, when exposure reliability was 0.7 and the observed sibling-correlation was r = 0.4, about 30-90% of the samples (n = 2,000) provided results supporting a false conclusion of confounding, depending on how p-values were interpreted as evidence for a family effect on the outcome. The current results have practical importance for epidemiological researchers conducting or reviewing sibling and co-twin control studies and may improve our understanding of observed associations between risk factors and health outcomes. We have developed an app (SibSim) providing simulations of many situations not presented in this paper.

While there is a growing literature about mental health problems among unaccompanied asylum-seeking and refugee minors (URMs), far less is known about their wellbeing. Such information is important as a subjective sense of wellbeing is associated with a variety of positive health and psychosocial outcomes. The aim of this study was to examine life satisfaction and the association with traumatic events, daily hassles, and asylum status among URMs in Norway. We collected self-report questionnaire data from URMs living in Norway (n = 173, 90.80% male, 71.1% from Afghanistan). Mean age was 16.62 (SD = 1.74) years, and they reported clinically relevant post-traumatic stress symptoms. We explored variation in life satisfaction, URM-specific daily hassles and traumatic events. We also investigated a mediation model, in which we assumed that daily hassles mediated the association between traumatic events and life satisfaction. The participants reported low life satisfaction (M = 4.28, SD = 2.90, 0-10 scale). A negative outcome of the asylum process and URM-specific daily hassles were associated with reduced life satisfaction. URM-specific daily hassles accounted for the relation between traumatic events and life satisfaction. The youth had been exposed to several traumatic events yet the effect of these on life satisfaction appeared indirect, via an increase in URM-specific daily hassles. Reducing the number of, or help URM cope with, URM-specific daily hassles may increase their life satisfaction.
RESUMEN
BACKGROUND: Compromised well-being and mental health problems pose a significant threat to individuals and societies worldwide. Resource-intensive psychological treatments alone cannot alleviate this burden. There is a need for low-cost, evidence-based interventions aimed at preventing illness and promoting well-being. Five activity domains appear to be linked with well-being promotion across populations: connecting with others, being active, taking notice, learning, and being generous/giving. The activities mentioned are part of the Five Ways to Wellbeing framework and the web-based intervention Five Ways to Wellbeing for All (5waysA). OBJECTIVE: This randomized controlled trial aims to test the effects of the 5waysA intervention, a web-based, low-cost, well-being-promoting measure targeting the general population. To date, the Five Ways to Wellbeing framework has not been tested in this specific format. The 5waysA intervention comprises 2 webinars and SMS text message reminders delivered over a 10-week period. METHODS: In 2021, a total of 969 study participants from various regions across Norway were openly recruited through a web page. They were then randomly assigned to either an intervention group or 1 of 2 waiting list control groups, namely, active or passive. Self-reported life satisfaction (Satisfaction With Life Scale [SWLS]), flourishing (Flourishing Scale [FS]), positive emotions, anxiety, and depression symptoms (Hopkins Symptom Checklist-8 [HSCL-8]) were assessed before the intervention, at 4 weeks into the intervention, and 1-2 weeks after the intervention (over 10 weeks). Data analysis was conducted using linear mixed (multilevel) models. RESULTS: After 10 weeks, 453 participants (171 in the intervention group and 282 in the waiting list control group) were assessed on outcome variables, with a dropout rate of 53.2% (516/969). Results revealed a significantly greater increase in the intervention group compared with the controls for SWLS (b=0.13, 95% CI 0.03-0.23; P=.001), FS (b=0.19, 95% CI 0.08-0.30; P=.001), positive emotions (b=0.43, 95% CI 0.27-0.60; P<.001), and these factors combined into a global well-being measure (b=0.28, CI 0.16-0.39; P<.001). Effect sizes (Cohen d) for the well-being outcomes ranged from 0.30 to 0.49. In addition, a significant decrease in anxiety and depressive symptoms was observed (b=-0.17, 95% CI -0.30 to -0.04; P=.001) with an effect size (Cohen d) of -0.20. CONCLUSIONS: The findings suggest that the web-based 5waysA intervention could serve as an effective approach for enhancing well-being and mental health within the general population. This study offers individuals, policy makers, and local stakeholders an accessible and potentially cost-effective well-being intervention that could be easily implemented.

The attachment and caregiving domains maintain proximity and care-giving behavior between parents and offspring, in a way that has been argued to shape people's mental models of how relationships work, resulting in secure, anxious or avoidant interpersonal styles in adulthood. Several theorists have suggested that the attachment system is closely connected to orientations and behaviors in social and political domains, which should be grounded in the same set of familial experiences as are the different attachment styles. We use a sample of Norwegian twins (N = 1987) to assess the genetic and environmental relationship between attachment, trust, altruism, right-wing authoritarianism (RWA), and social dominance orientation (SDO). Results indicate no shared environmental overlap between attachment and ideology, nor even between the attachment styles or between the ideological traits, challenging conventional wisdom in developmental, social, and political psychology. Rather, evidence supports two functionally distinct systems, one for navigating intimate relationships (attachment) and one for navigating social hierarchies (RWA/SDO), with genetic overlap between traits within each system, and two distinct genetic linkages to trust and altruism. This is counter-posed to theoretical perspectives that link attachment, ideology, and interpersonal orientations through early relational experiences.

The widespread comorbidity observed across psychiatric disorders may be the result of processes such as assortative mating, gene-environment correlation, or selection into population studies. Between-family analyses of comorbidity are subject to these sources of bias, whereas within-family analyses are not. Because of Mendelian inheritance, alleles are randomly assigned within families, conditional on parental alleles. We exploit this variation to compare the structure of comorbidity across broad psychiatric polygenic scores when calculated either between-family (child polygenic scores) or within-family (child polygenic scores regressed on parental polygenic scores) in over 25,000 genotyped parent-offspring trios from the Norwegian Mother Father and Child Cohort study (MoBa). We fitted a series of factor models to the between- and within-family data, which consisted of a single genetic p-factor and a varying number of uncorrelated subfactors. The best-fitting model was identical for between- and within-family analyses and included three subfactors capturing variants associated with neurodevelopment, psychosis, and constraint, in addition to the genetic p-factor. Partner genetic correlations, indicating assortative mating, were not present for the genetic p-factor, but were substantial for the psychosis (b = 0.081;95% CI [0.038,0.124]) and constraint (b = 0.257;95% CI [0.075,0.439]) subfactors. When average factor levels for MoBa mothers and fathers were compared to a population mean of zero we found evidence of sex-specific participation bias, which has implications for the generalizability of findings from cohort studies. Our results demonstrate the power of the within-family design for better understanding the mechanisms driving psychiatric comorbidity and their consequences on population health.

OBJECTIVE: Political attitudes are predicted by the key ideological variables of right-wing authoritarianism (RWA) and social dominance orientation (SDO), as well as some of the Big Five personality traits. Past research indicates that personality and ideological traits are correlated for genetic reasons. A question that has yet to be tested concerns whether the genetic variation underlying the ideological traits of RWA and SDO has distinct contributions to political attitudes, or if genetic variation in political attitudes is subsumed under the genetic variation underlying standard Big Five personality traits. METHOD: We use data from a sample of 1987 Norwegian twins to assess the genetic and environmental relationships between the Big Five personality traits, RWA, SDO, and their separate contributions to political policy attitudes. RESULTS: RWA and SDO exhibit very high genetic correlation (r = 0.78) with each other and some genetic overlap with the personality traits of openness and agreeableness. Importantly, they share a larger genetic substrate with political attitudes (e.g., deporting an ethnic minority) than do Big Five personality traits, a relationship that persists even when controlling for the genetic foundations underlying personality traits. CONCLUSION: Our results suggest that the genetic foundations of ideological traits and political attitudes are largely non-overlapping with the genetic foundations of Big Five personality traits.
RESUMEN
BACKGROUND: Stressful life events (SLEs) constitute key risk factors for depression. However, previous studies examining associations between SLEs and depression have been limited by focusing on single events, combining events into broad categories, and/or ignoring interrelationships between events in statistical analyses. Network analysis comprises a set of statistical methods well-suited for assessing relationships between multiple variables and can help surpass several limitations of previous studies. METHODS: We applied network analysis using mixed graphical models combining two large-scale population-based samples and >34,600 randomly sampled adults to investigate the associations between SLEs and current depressive symptoms in the general population. RESULTS: Numerous SLEs were uniquely associated with specific symptoms. Strong pairwise links were observed between SLEs during the past year and individual symptoms, e.g., between having experienced illness or injury and sleeping problems, having been degraded or humiliated and feeling blue, and between financial problems and hopelessness and being worried and anxious. Several SLEs, such as financial problems, sexual abuse, and having been degraded or humiliated, were associated with symptoms across more than one timepoint. More recent SLEs were generally more strongly associated with depressive symptoms. Several life events were strongly interrelated, such as multiple forms of abuse, and financial problems, unemployment, divorce, and serious illness or injury. LIMITATIONS: Limitations include a retrospective SLE measure, cross-sectional data, a brief self-report measure of depressive symptoms, and possible attrition bias in the sample. CONCLUSIONS: Our findings may have implications for public health efforts seeking to improve population mental health.

Few studies have assessed the multifactorial nature of environmental influences on population mental health. In this large-scale, population-based study of adults, we applied network analysis to study the relationship between environmental factors and symptoms of depression, anxiety, and well-being. We estimated networks with overall mental health nodes and individual symptoms to assess both broad and fine-grained associations between environmental factors and mental health. Finally, we conducted an out-of-sample replication in an independent large-scale sample to assess the robustness of our results. Across 31,000 adults randomly sampled from the Norwegian population, we identified associations between numerous environmental characteristics and mental health. Recent discrimination and unsupportive social environments were strongly associated with lower population well-being and higher levels of mental illness symptoms, respectively. The most strongly connected variables in the networks were environmental factors, including perceived problems with crime, violence, or vandalism in the residential area, worrying about violence or threats when outside, and problems with noise or contamination at home. Substantial variation in population mental health was explained by environmental factors included in the networks. Replicability of the results was excellent and suggestive of strong robustness of the results across samples. Our findings are indicative of the importance of environmental factors, such as the social environment, housing satisfaction, and residential area characteristics, for multiple aspects of population mental health. We identify several environmental factors that represent potentially useful targets for future studies and public health efforts seeking to improve mental health in the general population.

STUDY QUESTION: Do expectant parents experience increased anxiety and depression during pregnancies conceived through ART compared to spontaneous conception? SUMMARY ANSWER: Among all expectant parents in the sample, those who conceived through ART reported overall lower levels of anxiety and depression in pregnancy compared to expectant parents who conceived spontaneously, while in the subsample of parents who conceived both through ART and spontaneous conception, expectant mothers experienced increased anxiety and depression in early pregnancy following ART compared to spontaneous conception. WHAT IS KNOWN ALREADY: Previous research on expectant parents' psychosocial adjustment in response to ART has found mixed results, with some studies suggesting ART is associated with increased anxiety and depression, and other studies suggesting improved mental health or no relationship. Mixed findings may relate to the use of cross-sectional designs that do not account for confounding differences between groups, or variability in the timing of assessment. STUDY DESIGN, SIZE, DURATION: This prospective cohort study used data from the Norwegian Mother, Father and Child Cohort Study (MoBa), which includes 2960 pregnant women who underwent ART and 108 183 women who conceived spontaneously. Of these, a subsample of expectant parents had two consecutive pregnancies with one pregnancy resulting from ART and one conceived spontaneously (n = 286 women, n = 211 partners). Women self-reported their composite symptoms of anxiety and depression at two timepoints during each pregnancy (gestational weeks 17 and 30). Their partners self-reported composite symptoms of anxiety and depression at 17 weeks gestation during each pregnancy. Couples reported their relationship satisfaction at 17 weeks gestation. MAIN RESULTS AND THE ROLE OF CHANGE: Using a conventional full-cohort analysis we found that ART was associated with less total anxiety and depression and greater relationship satisfaction, compared to spontaneous conception among both women and men. However, in the subsample of parents who experienced both ART and spontaneous pregnancies, ART was associated with increased levels of maternal anxiety and depression at gestational age 17 weeks (M = 1.19), compared to spontaneous pregnancies (M = 1.15), 95% CI of the mean difference 0.006, 0.074. At 30 weeks gestation, anxiety and depression were similar across both types of pregnancies. Expectant fathers reported similar levels of anxiety and depression at 17 weeks gestation during both pregnancies. Among women relationship satisfaction was higher following ART conception than spontaneous conception. LIMITATIONS, REASONS FOR CAUTION: There is potential for selection effects in the sample, as women who have conceived through both ART and spontaneous conception in their first two pregnancies are rare. In addition, several factors that may be important predictors of mental health in this context, such as previous miscarriages and long-term infertility, were not assessed in the current study. WIDER IMPLICATIONS OF THE FINDINGS: Our findings indicate that previous discrepancies in the literature may be related to inherent differences between the groups of parents receiving reproductive treatment and those who do not. This study addresses that limitation by prospectively comparing different types of pregnancies within the same expectant parents. Earlier inconsistencies may also relate to variations in gestational age when anxiety and depression were assessed. By examining symptoms at two timepoints in each pregnancy, we were able to examine the relation between gestational age and symptoms of anxiety and depression. STUDY FUNDING/COMPETING INTEREST(S): The MoBa is supported by the Norwegian Ministry of Health and the Norwegian Research Council/FUGE (grant number 151918/S10). This work was also supported by the Research Council of Norway grant number 288083 and 301004. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER: N/A.

What are the major sources of worldwide variability in subjective well-being (SWB)? Twin and family studies of SWB have found substantial heritability and strong effects from unique environments but virtually no effects from shared environments. However, extant findings are not necessarily valid at the global level. Prior studies have examined within-countries variability but did not take into account mean differences across nations. In this article, we aim to estimate the effects of genetic factors, individual environmental exposures, and shared environments for the global population. We combine a set of knowns from national well-being studies (means and standard deviations) and behavioral-genetic studies (heritability) to model a scenario of twin studies across 157 countries. For each country, we simulate data for a set of twin pairs and pool the data into a global sample. We find a worldwide heritability of 31% to 32% for SWB. Individual environmental factors explain 46% to 52% of the variance (including measurement error), and shared environments account for 16% to 23% of the global variance in SWB. Worldwide, well-being is somewhat less heritable than within nations. In contrast to previous within-countries studies, we find a notable effect of shared environments. This effect is not limited to within families but operates at a national level.

BACKGROUND AND HYPOTHESIS: Around 5%-7% of the adult population are estimated to have lifetime psychotic experiences (PEs), which are associated with psychosis risk. PEs assessed with Community Assessment of Psychic Experiences (CAPE) are associated with psychosis but also non-psychotic disorders, which could be partly explained by CAPE indirectly capturing emotional symptoms. We investigated the psychometric properties of a shorter version, CAPE-9, and whether CAPE-9 scores are associated with lifetime psychotic or non-psychotic mental disorders after controlling for current anxiety and depressive symptoms. DESIGN: CAPE-9 questionnaire data were obtained from 29 021 men (42.4 ± 5.6 yrs.) from the Norwegian Mother, Father, and Child Cohort Study. We investigated CAPE-9 reliability and factor structure. Logistic regression was used to test effects of current anxiety and depressive symptoms (SCL-12) on associations between CAPE-9 scores and psychiatric diagnoses. RESULTS: CAPE-9 fit a previously reported 3-factor structure and showed good reliability. Twenty-six percent reported at least one lifetime PE. CAPE-9 scores were significantly associated with most psychiatric disorders (schizophrenia, depression, bipolar disorder, substance abuse, anxiety, trauma-related disorders, and ADHD). After controlling for concurrent emotional symptoms, only associations with schizophrenia (OR = 1.29; 95% CI = 1.18-1.38) and trauma-related disorders (OR = 1.09; CI = 1.02-1.15) remained significant. CONCLUSIONS: CAPE-9 showed good psychometric properties in this large population-based adult male sample, and PEs were more clearly associated with psychotic disorders after controlling for current emotional symptoms. These results support the use of the short CAPE-9 as a cost-effective tool for informing public health initiatives and advancing our understanding of the dimensionality of psychosis.

PURPOSE: The structure of well-being has been debated for millennia. Dominant conceptualisations, such as the hedonic and eudaimonic models, emphasise different constituents of the well-being construct. Some previous studies have suggested that the underlying structure of well-being may consist of one or a few general well-being factors. We conducted three studies to advance knowledge on the structure of well-being comprising more than 21,500 individuals, including a genetically informative twin sample. METHODS: In Study 1, we used hierarchical exploratory factor analysis to identify well-being factors in a population-based sample of Norwegian adults. In Study 2, we used confirmatory factor analysis to examine the model fit of the identified factor model in an independent sample. In Study 3, we used biometric models to examine genetic and environmental influences on general well-being factors. RESULTS: We identified six well-being factors which all loaded on a single higher-order factor. This higher-order factor may represent a general "happiness factor", i.e. an h-factor, akin to the p-factor in psychopathology research. The identified factor model had excellent fit in an independent sample. All well-being factors showed moderate genetic and substantial non-shared environmental influence, with heritability estimates ranging from 26% to 40%. Heritability was highest for the higher-order general happiness factor. CONCLUSION: Our findings yield novel insights into the structure of well-being and genetic and environmental influences on general well-being factors, with implications for well-being and mental health research, including genetically informative studies.

BACKGROUND: Unaccompanied asylum-seeking and refugee minors report low life satisfaction and high levels of mental health problems, nevertheless they often do not seek or receive help for their problems. Teaching Recovery Techniques (TRT) is a low-threshold, five sessions intervention developed to reduce distressing war- and disaster-related trauma reactions among children and youth. In this study, we investigate if TRT can contribute to increased life satisfaction among unaccompanied asylum-seeking and refugee minors. METHODS: Asylum-seeking and resettled unaccompanied minors participated in TRT carried out in 15 locations throughout Norway, n = 147, mean age = 16.61 (SD = 1.80), 88% boys, and 67% from Afghanistan. Life satisfaction was measured by the Cantril Ladder before the intervention, and two- and eight weeks post-intervention. We also included indices of intervention compliance and contextual variables, such as asylum status. We applied a pre- and post-intervention design with linear mixed model analyses to investigate change in life satisfaction. RESULTS: Life satisfaction significantly increased from pre- to post- intervention, but not for youth whose asylum application had been rejected or who were still awaiting a decision. Indices of intervention compliance were associated with an increase in life satisfaction. CONCLUSIONS: TRT is a potential useful intervention to enhance life satisfaction among unaccompanied asylum-seeking and refugee minors and can be a measure to support positive development among youth at risk for mental health problems. However, TRT initiatives should consider the participant's stage of asylum process, because harsh immigration policies may overburden the coping capacity. Without further adaptation, TRT seems most useful for youth granted residence. The manual has been revised to include asylum-related stressors.

Within-family studies typically assess indirect genetic effects of parents on children, however social support theory points to a critical role of partners and children on women's depression. To address this research gap and account for the high heterogeneity of depression, we calculated a general psychiatric factor using eleven major psychiatric polygenic scores (polygenic p), in up to 25,000 parent-offspring trios from the Norwegian Mother, Father and Child Cohort Study (MoBa). Multilevel modeling of trio polygenic p was used to distinguish direct and indirect genetic effects on mothers depression during pregnancy (gestational age 17 and 30 weeks), infancy (6 months, 18 months) and early childhood (3 years, 5 years, and 8 years). We found mothers polygenic p predicts their depression symptoms (b = 0.092; 95 % CI [0.087,0.098]), outperforming prediction using a single major depressive disorder polygenic score (b = 0.070, 95 % CI [0.066,0.075]). Jointly modeling trio polygenic p revealed indirect genetic effects of fathers (b = 0.022, 95 % CI [0.014,0.030]) and children (b = 0.021, 95 % CI [0.010,0.037]) on mothers' depression. Our results support the generalizability of polygenic effects across mental health and highlight the role of close family members on women's depression.
