  Objective To (1) identify multivariable longitudinal midlife patterns of systolic and diastolic blood pressure, body mass index, and non–high density lipoprotein cholesterol and (2) assess whether electrocardiogram derived heart age acceleration (δ-age) mediates their associations with incident myocardial infarction (MI), stroke, and all-cause mortality. Patients and Methods We analyzed 5244 participants from the observational cohort study, the Tromsø Study, who were free of MI or stroke at baseline (Tromsø7, 2015-2016) and attended at least 3 surveys (Tromsø3-7, 1986-2016). Age-standardized risk factor z-scores were modeled with quadratic B-splines and grouped using K-means clustering to identify joint multivariable life-course risk profiles. δ-Age was derived from 12-lead electrocardiograms using a validated neural network. Natural-effects models decomposed hazard ratios between clusters and clinical events (follow-up to 2021) into direct and δ-age mediated components. Results Four distinct clusters were identified: stable low-risk (cluster 1, n=1604, 30.6%), dyslipidemia (cluster 2, n=1340, 25.6%), hypertension (cluster 3, n=1476, 28.1%), and high-risk trajectory (cluster 4, n=824, 15.7%). Each 1-SD increment in δ-age was associated with 27% to 30% of excess MI, stroke, and death, independent of age and sex. Clusters 3 and 4 carried the greatest excess risk of clinical events, whereas mediation by δ-age was modest (4%-8% of total effect for MI and stroke) and not statistically significant. Conclusion Joint multivariable life-course clustering of conventional risk factors identified clinically distinct long-term cardiovascular risk phenotypes. Although δ-age adds independent prognostic information, it explained little of the excess risk associated with chronic hypertension, dyslipidemia, or obesity, indicating it functions primarily as a parallel marker and not a causal mediator.

Resilience and clinical recovery in first-episode schizophrenia: a 10-year longitudinal study of clinically recovered, non-recovered, and healthy control participants.

  Introduction Research on resilience in clinical recovery following first-episode schizophrenia (FES) remains limited, and few longitudinal studies achieve sufficient retention to capture long-term trajectories. To address this, the Oslo Schizophrenia Recovery Study (OSR) was designed to examine resilience over time in FES. Investigating resilience is essential for understanding how individuals exposed to schizophrenia may achieve favorable outcomes. We addressed two primary questions: First, how does resilience change over time in individuals with FES compared with healthy controls. Second, whether longitudinal resilience trajectories within the FES group differ between participants who meet predefined clinical recovery criteria compared to those who do not. Methods Repeated assessments were conducted across 12 clinical evaluations. The sample comprised 28 individuals with FES and 28 healthy controls. Resilience was measured with the Connor–Davidson Resilience Scale, and social and role functioning were indexed using the Global Functioning Scales. The data were analyzed using linear multilevel models. Candidate longitudinal mixed-effects models were compared using the small-sample corrected Akaike Information Criterion (AICc), with parameters estimated by maximum likelihood. Results At 10-year follow-up, retention was 79%. Half of the FES group achieved clinical recovery. Model estimates indicated increasing resilience over time in the FES group, whereas resilience in healthy controls remained relatively stable, although statistical support for differential trajectories between groups was limited. Clinically recovered individuals showed a steeper increase in resilience. In contrast, non-recovered individuals exhibited only modest, gradual improvements, with resilience levels remaining lower at study completion. Conclusion Different resilience trajectories were observed between clinically recovered and non-recovered individuals with FES, with greater improvements in resilience associated with recovery. Although causality remains uncertain and differences to healthy controls were less robust, these findings highlight the value of repeated longitudinal assessments of resilience in FES, both to more precisely characterize resilience trajectories and to reduce drop-out rates.

  With population aging, understanding the frequency and distribution of decisions to attempt or withhold cardiopulmonary resuscitation (CPR) in long-term care populations is increasingly important. In Oslo, CPR status, that is, an advance decision about whether CPR should or should not be attempted, is systematically assessed and documented for all long-term care residents. Comprehensive register data therefore provide a unique opportunity to assess advance CPR decisions at the population level. We obtained cross-sectional data on the documented CPR status of nearly all persons aged 50+ years admitted to public or private long-term care facilities in Oslo between 2018 and 2023 (N = 7860). We examined the proportion of long-term care residents with documented positive CPR status (CPR should be attempted) and used multivariable logistic regression to analyze the associations between documented positive CPR status and age, sex, marital status, primary contact (e.g., son, daughter, spouse, professional), functional limitations, institutional relocations, duration of stay, and year of admission. We found that 9.2% of long-term care residents had documented positive CPR status. Documented positive CPR status was related to younger age, fewer limitations, shorter duration of stay, and fewer relocations. Compared with residents first admitted in 2018, documented positive CPR status was less likely among those first admitted between 2019 and 2022, but not among those first admitted in 2023. There was no evidence that documented positive CPR status was related to sex, marital status, primary contact. Our findings provide population-level evidence on documented CPR status in long-term care and highlight the need for future research on how such decisions are made.

  Abstract When listening to novel music, extra-musical information about the musician may influence a listener's evaluations of the music. Here, we studied the extent to which information about the musicians’ Humanness, Morality and Sex, conveyed by their vocal timbre and tessitura, affected listeners’ emotional and aesthetic responses to their music. This online, pre-registered experiment followed a 2 (Humanness: Human vs. AI model) × 2 (Vocalist Sex: Male vs. Female) × 3 (Morality: Moral, Immoral, Neutral) mixed factorial design. Participants (n = 400) were randomly assigned to one of four groups, differing in Humanness and Vocalist Sex. Participants read three descriptions depicting a Moral, Immoral and Neutral behaviour and listened to three unfamiliar songs pseudorandomly paired with a description. Emotional and aesthetic responses to each song were measured using validated measures (GEMS-9 scale) and additional items assessing feelings of being Moved, Connected, perceived Beauty, Liking and perceived Creativity. As predicted, linear mixed-effects models revealed significant main effects of Morality for all dependent variables, with Immoral descriptions consistently yielding more negative ratings. Contrary to predictions, we observed no differences in responses to songs based on Humanness, no significant interaction between Morality and Humanness and no effect of Vocalist Sex on responses.

  Behavioral science has achieved remarkable policy influence, yet the problems it addresses, such as climate change, health inequality, and financial precarity, have worsened. We argue this is no coincidence. The field suffers from systematic power-blindness: it treats individuals as abstract decision makers while bracketing the structural forces that shape their behavioral possibilities. This article develops the responsibility–power–justice (RPJ) nexus framework as a corrective, advancing two foundational claims. First, power is not external to behavior but constitutive of it; every behavioral intervention embeds claims about who bears responsibility for problems and solutions. Second, justice is not a normative standard applied after behavioral analysis, but a causal mechanism operating within it: Tax compliance depends on perceived fairness, health behaviors reflect institutional trust, and cooperation requires beliefs about equitable burden-sharing. Across climate policy, public health, and economic governance, we demonstrate a consistent pattern: powerful actors reframe structural problems as individual failures, behavioral science supplies the intellectual tool kit, and interventions redistribute responsibility downward while leaving power structures intact. We trace this pattern to the field’s roots in methodological individualism, its privileging of individual-level experiments, and its institutional entanglement with prevailing governance arrangements. We conclude by outlining what a justice-oriented behavioral science would require.

  Objective: It has been hypothesized that shame and fear of receiving compassion from others are interrelated processes in psychotherapy. However, little is known about how these factors influence each other in a clinical setting. This study examined the relationships between shame, fear of receiving compassion from others, and symptom distress at a within-patient level throughout psychotherapy. Method: The transdiagnostic sample consisted of 1,134 inpatients at Modum Bad receiving psychological treatment. Weekly self-reports measured symptom distress, fear of receiving compassion, and shame. The Latent Curve Model with Structured Residuals was used to examine the relationships between the variables at a within-patient level throughout therapy. Results: At a within-patient level, reciprocal predictive relationships were found between shame and symptom distress, and between fear of receiving compassion and symptom distress. Shame also predicted fear of receiving compassion, but not vice versa. Sensitivity analyses supported the relationship between shame and symptom distress across treatment units but indicated greater variation in relationships involving fear of receiving compassion. Conclusion: The findings suggest that shame and fear of receiving compassion are dynamically involved in symptom change during psychotherapy. Shame appears particularly central, whereas the role of fear of receiving compassion may vary across treatment contexts.

  Formålet med denne studien er å få økt innsikt i barns initiativ i samtale med barnehagelærer ved å studere forekomst av og samtalekonteksten rundt initiativene deres, og hvorvidt disse forholdene varierer for enspråklige og flerspråklige norske barn. I studien analyseres samtaler knyttet til en bildebok i 14 par med barnehagelærer og fem år gamle barn ved hjelp av initiativ–respons-analyse (IR-analyse) (Linell & Gustavsson, 1987). Resultatene viser at de enspråklige barna tar flere initiativ enn de flerspråklige, og at barnehagelærerne i større grad stiller spørsmål til de flerspråklige barna etter initiativene deres. Felles for alle barna er at det ser ut til at spørsmål fra barnehagelærer begrenser barnas muligheter til å påvirke samtalen. En samtalestrategi der barnehagelærer i mindre grad stiller spørsmål og i større grad følger barnets initiativ, kan bidra til å åpne opp for barnets bidrag og påvirkning, noe som kan være positivt både for barnets deltagelse og for dets språklige utvikling.

  Background Implementation of evidence-based interventions is one of the proposed responses to increased demand for treatment of adolescent depression. While the efficacy of interpersonal psychotherapy to treat depression of adolescents (IPT-A) is well established, the shorter adolescent interpersonal counseling (IPC-A) was implemented in primary care in Finland due to better feasibility. We present a protocol for a prospective evaluation of whether implementation of IPC-A has improved the naturalistic treatment flow and outcome of adolescents with sustained depression. We will evaluate the comparative effectiveness and cost-effectiveness of IPC-A and other treatment options, as compared to no treatment of sustained depression. Methods We will collect a prospective cohort of grade 7 to 9 adolescents (13 to 17-year-olds) in selected Finnish schools using convenience sampling (n = 9000). We will describe the comparative effectiveness of naturalistic treatment, with an aim to compare three groups as defined at 6 months (with IPC-A, n = 100; with other psychosocial treatment, n = 200; or no treatment, n = 100). The primary outcome measure will be the proportion of adolescents who received specialized psychiatric services by 2 years after baseline in each group. Secondary outcome measures will include longitudinal changes in PHQ-9-A scores by 12 months, positive mental health, social inclusion, and quality of life. Cost-effectiveness will be evaluated using survey data at 12 months, and an economic evaluation using register data and information on service use 12 months before and up to 10 years after baseline. A universal evaluation of all adolescents, independent of mood, will provide prospective description of adolescents a) with sustained depression over the follow-up period (Patient Health Questionnaire 9 items, adolescent version, PHQ-9-A ≥ 10 in two measurements over 6 months), b) with a self-reported need and motivation for support, c) with therapeutic intervention, and d) benefits and harms of treatment. We will describe the treatment received and predictors of treatment and outcome based on reports from adolescents, caretakers, and therapists, as well as electronic patient records. Impact of training in IPC-A on competence and access to treatment will be evaluated. Discussion The study will describe need for, pathways to, and content of mental health services for depressed adolescents over the two years following national implementation of IPC-A. The results can improve equal access to care, and inform decision makers about the best practices for treatment of depression, including utility of the implementation of IPC-A.

  Climate change and violent extremism represent intersecting global threats, yet their relationship remains under-examined. This preregistered systematic review synthesizes 45 studies across disciplines to develop an integrated conceptual model of climate-extremism pathways based on the current literature. Our synthesis shows that climate variability correlates with terrorist attack frequency, climate shocks create governance vacuums exploited by extremist organizations, environmental degradation fuels extremist narratives, and climate threat cues increase authoritarian attitudes and out-group hostility. These pathways are moderated by various factors including state capacity, community resilience, and pre-existing ideologies. Our proposed Integrative Climate-Extremism Model distinguishes between extremist endorsement (attitudinal support), advocacy (recruitment and propaganda), willingness (behavioral intentions), and execution (violent acts), outlining how each is influenced by different pathways. This synthesis reveals climate change as a threat multiplier rather than direct cause of violent extremism, operating through material, institutional, psychological, and ideological mechanisms. We identify critical research gaps, propose targeted interventions to disrupt climate-extremism pathways, and discuss anticipatory governance strategies.

  Abstract Early adolescence is a common period of onset for depressive symptoms. In part, this may reflect a developmental expression of individuals’ genetic propensities as they undergo physiological and hormonal changes and interact with new environments. Many commonly proposed mechanisms assume direct effects of an individual’s own genes on emerging variation in their depressive symptomatology. However, estimates of genetic influence based on analyses in unrelated individuals capture not only direct genetic effects but also genetic effects from parents and other biologically related family members. In data from the Norwegian Mother, Father and Child Cohort (MoBa), we used linear mixed models to distinguish developmentally-stable and adolescence-specific direct and parental indirect genetic effects. In within-family models, we examined effects of polygenic scores for major depressive disorder (MDD), ADHD, anxiety disorders, and educational attainment (EA) on depressive symptoms measured at ages 8 and 14. Children’s own MDD polygenic scores showed adolescence-specific effects on depressive symptoms (β PGS*wave =0.041, [95% CI: 0.017, 0.065]). Developmentally-stable direct effects from children’s polygenic scores for MDD (β = 0.016, [0.006, 0.039]), ADHD (β = 0.024, [0.008, 0.041]) and EA (β=-0.02, [ -0.038, -0.002]) were also evident. The only evidence of indirect genetic effects was a stable effect of maternal EA polygenic scores (β = 0.04, [0.024, 0.054]). Direct genetic effects linked to genetic liability to MDD accounted for emerging variation in depressive symptoms in adolescence. These results imply that specific etiological mechanisms related to MDD may become particularly relevant for depressive symptoms during early adolescence compared to at earlier ages.

Fulltekst i vitenarkiv Vis sammendrag

  Abstract Background Neurodivergent youth and youth with pre‐existing psychiatric disorders may have faced additional challenges in navigating the demands and restrictions of the COVID‐19 pandemic. However, less is known about how mental health outcomes and psychiatric healthcare utilization differed across diagnostic groups and other youth‐related factors. This systematic review synthesizes evidence on mental health symptoms and psychiatric healthcare use among youth with pre‐existing conditions during the pandemic. Methods We searched PubMed, Web of Science and additional sources for cross‐sectional and longitudinal studies with data collected between March 2020 and May 2023. Eligible studies included neurodivergent youth and/or youth with psychiatric disorders confirmed through clinician diagnosis or medical records prior to the pandemic. Given the clinical and methodological diversity of studies, findings were synthesized narratively. Results Forty‐eight studies met the inclusion criteria. Mental health outcomes showed mixed patterns both across and within diagnostic groups, with individual studies reporting symptom increase, stability and improvements. Evidence on psychiatric healthcare utilization was more limited and suggested different patterns between service use and psychotropic medication use. Compared to boys, girls were more likely to experience COVID‐related distress and increases in psychiatric service use during the pandemic. Age‐related findings varied across developmental stages and outcome domains. Most studies ( n  = 40; 83.3%) had a moderate overall risk of bias (RoB), while seven (14.6%) had a high overall RoB. Conclusion Mental health outcomes among youth with pre‐existing conditions during the COVID‐19 pandemic varied both within and across diagnostic groups. Outcomes were also associated with individual, developmental, contextual and service‐related factors. These findings suggest the importance of considering such factors alongside diagnosis when identifying clinical needs and planning support during large‐scale societal disruptions. Evidence on psychiatric healthcare utilization remains limited. More methodologically robust research is needed to clarify mental health and healthcare‐use patterns during major public health emergencies.

  Our understanding of the genetic architecture of obesity is primarily based on studies of adults, with sparser data from childhood. Here, we conducted age-stratified genetic association studies against objectively measured ( n  = 62,276) or recalled childhood adiposity-related traits ( n eff  = 599,924), identifying 624 common variants associated with childhood adiposity, with one-third having no concordant association with adult body mass index. Signals linked to the leptin–melanocortin pathway ( BSX , GNAS , LEPR and PCSK1 ) and incretin signaling ( GIPR and GLP1R ) showed childhood-specific effects on adiposity. Single-nucleus RNA sequencing data identified childhood-specific adiposity-regulating cell populations in the arcuate nucleus and mammillary bodies, indicating neurocircuits that regulate adiposity specifically during childhood. Finally, sequencing in 479,615 individuals uncovered rare protein-coding variation in ADCY3 , CALCR , MC4R , MRAP2 , POMC and MYH13 , exhibiting stronger associations in childhood than in adults. Our findings suggest that childhood provides a more sensitive window for the study of key endocrine and neuropeptide pathways that regulate energy balance.

  To advance the science of positive emotional expressions, we test how 22 positive emotions are spontaneously displayed on the face, using the participant-negotiated episodic recall method. Respondents (n = 163) narrated emotional events from their lives, and we extracted facial behaviours that reflected peak expressivity (35 410 facial actions). Network models were applied to probe whether specific positive emotions would be conditionally associated with particular facial behaviours. Our results point to three sets of positive emotions: five that do not seem to have specific facial actions related to them (e.g. admiration), nine whose expressions do not significantly involve smiling (e.g. head turn for interest, raised chin for determination), and eight whose facial expressions include smiling as a unique expressive feature (e.g. positive surprise and elation). Notably, nine of these positive emotions had expressive patterns that were distinct from the other emotions in our set (e.g. raised cheeks and closed eyes for sexual desire), while eight emotions were associated with expressive patterns that were shared in pairs (e.g. raised eyebrows for both hope and inspiration). These results provide a tentative map of what specific positive emotions look like when produced on the face in a naturalistic situation. This article is part of the theme issue ‘Mechanisms, development, phylogeny and functions of emotional expressions’.

  Gratitude is a key contributor to well-being, yet the roles of individual factors such as age, gender, and socioeconomic status in this relationship remain unclear. In addition, little is known about whether this relationship varies across cultural and societal contexts. Across three studies (total N= 220,204; 67 countries) using cross-sectional data, we show that well-being is closely tied to gratitude experiences, with no meaningful universal individual differences across age, gender, socioeconomic status, or education. However, we did nd that the strength of this connection varied across countries, which could be explained by various country-level moderators. For instance, the link was weaker in countries with lower national income and more collectivistic values. These patterns establish the strong connection between gratitude and well-being across a wide variety of cultures, but also suggest that gratitude may be less strongly associated with well-being in contexts where resources are scarce. As the rst systematic study to examine the gratitude-well-being relationship across a broad range of individual and contextual differences, these ndings underscore the signi cant role of gratitude in well-being and reveal both the universal as well as the contextually contingent aspects of this connection.

  Recent decades have seen a surge of research revealing the core, early emerging psychological building blocks for navigating human societies. Yet, how such core motives operate across life, undergirding political ideology, remains unknown. Here we use the same kind of minimal, abstract group stimuli across the lifespan to show that gendered preferences for majority groups manifest among preschoolers and adults alike (but not among preverbal infants) and that they motivate support for sustaining intergroup hierarchies (for example, ethnic persecution, militarism and social welfare opposition) among adults. Preschool (N = 317) boys, but not girls, preferred majority rather than minority members, whereas infants (N = 180) chose randomly between the two. Among adults (N = 3,467), males also liked the majority more than females, and these coalitional preferences correlated robustly with political ideology. These results indicate that gendered motives for intergroup formidability are rooted in earliest childhood once children begin navigating peer relationships independently.

  Although educational attainment is heritable, years-of-education (EduYears) measures are not designed to show how genetic associations vary across discrete educational milestones. In the Norwegian Mother, Father and Child Cohort Study (MoBa; N = 120,527) and the Norwegian Twin Registry (N = 8,910), we combined genome-wide association studies (GWAS), polygenic indices (PGIs), and twin models to characterize genetic associations with high-school completion and bachelor’s, master’s, and doctoral attainment. In transition-specific analyses conditional on prior attainment, observed-scale common-variant heritability (h 2 SNP ) and PGI discrimination followed an inverse-U pattern, peaking for progression from high-school completion to attainment of at least a bachelor’s degree (HS → BSc + ; h 2 SNP  ≈ 0.14; R 2 Tjur  ≈ 0.05) and declining at postgraduate transitions. Genetic correlations (r g ) with large-scale GWAS of EduYears (EA4) and intelligence were high at earlier transitions but lower at later ones (for EA4, r g  ≈ 0.92 at HS → BSc+ and ≈ 0.38 at MSc → PhD). In cumulative analyses of attained status in the full cohort, the point-estimate gap between twin- and SNP-based heritability narrowed from ≈ 0.38 at high-school completion to ≈ 0.11 at PhD, while genetic overlap was lower for distant than adjacent milestones (r g  ≈ 0.71 for high-school completion versus PhD and ≈ 0.92 for adjacent milestones). Sensitivity analyses using an alternative intelligence GWAS and additional PGIs showed similar transition-specific trajectories. At the doctoral transition, estimates were obtained among individuals who had attained at least a master’s degree, so attenuation there must be interpreted in light of selection and range restriction. Because EduYears converts distinct credentials and progression steps into a single numerical scale, estimates expressed per additional year should not be interpreted as though one year has the same meaning across the educational sequence. Milestone-preserving analyses make that hidden structure visible and sharpen the interpretation of education GWAS and PGIs.

Failure to detect entorhinal grid-like signals in a passive navigation human fMRI study. Imaging Neuroscience. 4. doi: 10.1162/imag.a.1196. Fulltekst i vitenarkiv Vis sammendrag

  Abstract Grid cells in the human entorhinal cortex (EC) play a critical role in spatial navigation and memory. The EC is also one of the first regions affected by ageing and Alzheimer’s disease. This pre-registered functional magnetic resonance imaging (fMRI) study aimed to detect grid-cell-like signals (GLS) in a passive virtual navigation task. Contrary to our hypotheses and previous findings, we did not observe significant GLS at a population level, even in younger participants. Further exploratory analyses investigated the impact of task-engagement, as inferred from object-location memory performance, and showed no relationship with GLS magnitude. We also examined potential influences of a confounding one-fold directional signal and various data-processing choices but observed no consistent patterns. Our findings, consistent with recent null results from similar studies, suggest that passive navigation paradigms may be insufficient for reliably eliciting grid-like signals in human fMRI.

How Well Do Life Satisfaction Scores Reflect People’s Wellbeing? Insights from a Multidimensional, Machine Learning Approach. Fulltekst i vitenarkiv Vis sammendrag

  Life satisfaction is widely used as a primary indicator of population wellbeing in both scientific research and political decision-making. Yet, it remains unclear what global life evaluations capture across the broader landscape of wellbeing. In a UK sample (N = 1,050), we examined how four global life evaluation measures reflected experiences across 15 wellbeing domains. Machine learning analyses identified optimism, personal circumstances, happiness, and meaning and purpose as the strongest predictors, with other domains contributing comparatively little additional predictive information. Crucially, domains’ contributions corresponded only weakly with self-reported importance, challenging the assumption that unequal contributions reflect what people value most. Global wellbeing measures (e.g., life satisfaction scores) thus appear to provide selectively weighted rather than broad summaries of wellbeing, potentially underrepresenting domains people consider important. Researchers and policymakers seeking comprehensive or value-based assessments may therefore benefit from complementing global measures with multidimensional or domain-specific assessments.

  In his book, To Have and Have Not: The Determinants of Social Status in England, 1600-2026, Gregory Clark argues that a simple model with genetic transmission and assortative mating is sufficient to explain why socio-economic outcomes tend to run in families. Additionally, he provides a collection of arguments against the idea that environmental effects are important contributors to the similarities in outcomes he documents within extended families. Here, I raise two criticisms of Clark’s explanatory framework, and for each criticism suggest ways to mitigate it without introducing environmental effects. First, I criticize the framework for requiring that mates are highly correlated on unobserved traits that are highly heritable and highly genetically correlated with the outcome to be explained. I here suggest allowing for genotypic population stratification. Second, I criticize the framework for underestimating the importance of zygosity for the similarity of twins. As a fix for this, I suggest incorporating non-additive genetic effects.

  In a sample of 180,194 genotyped norwegians, we have correlations on polygenic scores for both height and educational attainment for 446,779 pairs of relatives, across 20 categories. There are 7 categories of biological relatives and 13 categories of relatives-in-law, connected by increasingly long chains of sibling, parent/child and marriage links, going out as far as six links. For height PGIs, we find that the pattern of correlations aligns well with a simple model of direct phenotypic assortment. For educational attainment, however, PGI correlations between distant in-laws are much too high for direct assortment. And models with indirect assortment on an unobserved trait can fit these data only if this trait is very highly correlated between mates and siblings. We present an alternative mechanism for assortative mating, where mating only occurs within segregated sub-populations, and where movements between sub-populations are uncommon and phenotype dependent. Through simulations, we show that such a model of assortment, which we name “the island model”, can account for our set of PGI correlations without the need for extreme assumptions about an unobserved assortment phenotype. Additionally, the model is consistent with recent studies of migration patterns within nations, showing that movements between rural and urban areas correlate with EA4 PGIs. Implications for behavioral genetic models assuming standard phenotypic assortment are discussed. And so are various properties of this island model, such as equilibrium conditions, and the consequences of sub-population specific shared-environmental effects.

  Are moral and prosocial people also happier in everyday life? Existing research is mixed: endorsing prosocial values is often linked to higher well-being, yet acting to help others can entail personal costs in the moment. One reason may be that most studies examine values rather than daily value-consistent behaviour, and rarely distinguish between momentary and longer-term well-being. We address these gaps using ecological momentary assessment data from more than 10,000 adults (120 beeps in total per person). At baseline, participants reported their moral and prosocial values. During the assessment period, they received four prompts per day asking whether they had (a) acted like a good, moral person and (b) taken care of or helped someone, alongside a broad set of well-being indicators (e.g., positive emotions, negative emotions, life satisfaction, meaning, social well-being, engagement). This design allows us to quantify the extent to which people behave in line with their values across days, and to link both values and daily behaviour as well as value–behaviour congruence to momentary and long-term well-being. Ongoing analyses will clarify when, and for whom, “being good” is associated with “feeling good”.

  Introduction The global rise in mental health problems and compromised wellbeing highlights the need for scalable and cost-effective wellbeing interventions. The Five Ways to Wellbeing for All (5waysA) is a digital adaptation of the UK’s Five Ways to Wellbeing framework, promoting wellbeing through five activity domains: connect, be active, take notice, keep learning, and give. Delivered via two webinars and SMS reminders over ten weeks, the 5waysA program aims to enhance wellbeing and reduce psychological distress in the general population. Methods A large-scale randomized controlled trial (N = 969) and subsequent secondary analyses were conducted in Norway. Self-reported life satisfaction, flourishing, positive emotions, anxiety, and depression were assessed pre-, mid-, and post-intervention. Analyses included multilevel modeling, mediation analysis, and network intervention analysis (NIA). A 12-month follow-up study with synthetic control comparison examined long-term effects. Findings Compared to waiting-list controls, participants in the intervention group reported significantly greater improvements in wellbeing (life satisfaction, flourishing, positive emotions) and reductions in anxiety and depressive symptoms (Cohen’s d = 0.20–0.49), with larger effects among those with most pre-intervention symptoms. Mediation analyses indicated that engagement in the Five Ways activities partially explained these effects, with a clear dose–response relationship between activity engagement and wellbeing outcomes. NIA revealed that increased positive emotions represented the main direct pathway, linking the intervention to improved wellbeing. Long-term follow-up demonstrated sustained gains in life satisfaction at 12 months (d = 0.28), exceeding simulated population-level controls (d = 0.17). Conclusions The 5waysA program effectively promotes wellbeing and reduces distress through accessible, evidence-based activities. Its digital, low-cost format, and durable effects make it a promising large-scale strategy for population-level mental health promotion and positive psychological functioning.

  Recent research suggests that cognitive facets of trait empathy may facilitate interpersonal synchrony. However, the contributions of affective trait empathy and state empathy remain underexplored. This study investigated how empathy – both as a dispositional characteristic and as an experimentally induced state – influences rhythmic entrainment and interpersonal synchrony in a musical context. Thirty-three dyads completed two synchrony tasks before and after an empathy induction session. In Task 1, participants tapped with a metronome and then tried to synchronise with their partner's tapping; in Task 2, they tried to play melodies in synchrony. To induce empathy, participants narrated personal events while partners were instructed to either empathise (empathy condition) or memorise factual details (control condition) of the events. Trait empathy was measured using the Interpersonal Reactivity Index (IRI; Davis, 1980). Emotional sharing and behavioural mirroring during the empathy induction were assessed using self-report and motion-capture measures. Results showed that both affective and cognitive trait empathy contributed to synchrony: Higher Empathic Concern predicted more consistent tapping in Task 1, and higher Fantasy predicted greater interpersonal synchrony in Task 2. Induced empathy showed no main effects; however, high-Fantasy participants who felt more emotionally engaged with their partners' narrations synchronised better than those who were less engaged. Additionally, high-Fantasy participants showed greater mirroring of narrators' head movements, although this was significant only in the control condition. These findings point to a multifaceted role of empathy in rhythmic and interpersonal synchronisation, suggesting that effective coordination draws on both cognitive and emotional aspects of empathy.

  Many countries have experienced substantial declines in fertility, later transitions to parenthood, and increased use of assisted reproductive technologies (ART). These changes can matter for demographic patterns, but also for health, wellbeing, and labour market trajectories across the life course. Family formation may affect health and employment in different, potentially opposing, ways. Parenthood and grandparenthood can provide meaning and social support, but they may also involve stress, care responsibilities, and economic costs. Similarly, difficulties conceiving and undergoing fertility treatment might affect mental health and working life well beyond the treatment period. Yet we do not fully understand how these different experiences of family formation are associated with health and labour-market outcomes over the life course. Consequently, this thesis examines how different family formation processes relate to health, sick leave, and employment, with a particular focus on gender differences. The three papers of this thesis consider distinct but connected stages of the family life course: parenthood, grandparenthood, and infertility treatment. Paper 1 studies differences in mental health between parents and childless individuals across the full adult life course. Parents have a consistently lower risk of mental disorders than the childless, even when adjusting for important confounders such as socioeconomic status and marital status. We find the lowest risk of mental disorders among individuals who have not yet become parents. This suggests that the observed parent–childless gap at least partly reflects selection into parenthood rather than a protective causal effect of having children on mental health. Importantly, we also find differences in the association depending on the specific mental health condition studied, with certain symptoms such as stress more likely among parents. Paper 2 examines the causal effects of becoming a grandparent on health and labour market outcomes, again with particular attention to gender. The results show that grandparenthood affects both health and employment, although the magnitude and direction of effects vary across outcomes. Becoming a grandparent is associated with an increased risk of respiratory infections, a reduction in cardiovascular-related health care use, and a slightly lower risk of mental disorders. It also marks a clear transition in labour market attachment: both women and men become more likely to work part-time and experience reductions in income. The employment effects are substantially larger among grandmothers. These gender differences may reflect women’s greater involvement in informal childcare. (Paper 3: not published) Taken together, the three papers show that family formation is linked to health and working life in varying ways across the life course. The papers also illustrate how family formation reflects gendered processes. The thesis highlights the importance of selection into parenthood, identifies grandparenthood as a meaningful life-course transition with health and economic consequences, and shows that unsuccessful fertility treatment may have lasting effects on mental health and employment. By examining these processes together, the thesis shows that family formation is not only an isolated reproductive event, but also a potential source of gender differences and inequalities in health and economic wellbeing.

  Siblings of children with chronic disorders (herein siblings) have heightened risk of developing mental health problems. Mental health problems are a major cause of disability among children and adolescents, leading to significant societal costs. Most sibling studies have examined group differences in risk and focus on sibling mental health outcomes rather than investigating individual -and family-level variables on a range of sibling outcomes. Although the Health Personnel Act (§ 10a) imposes duty on Norwegian health care professionals to provide information and support to caregivers and siblings of people with health care needs, there are still no unified evidence-based approach to inform health care workers on how to enact this duty for siblings. Consequently, there are large differences in how, when -or if at all, siblings are supported. Research that aims to understand the complex risk and protective factors for siblings is needed to develop effective and evidence-based preventive interventions. This thesis is focused on understanding the relationship between risk and protective factors associated with sibling psychosocial adjustment and includes three peer-reviewed and published studies. Paper 1 is a systematic review of social support for siblings of children with neurodevelopmental disorders. My co-authors and I found that social support is a potential key protective or risk factor depending on its level, however there were large differences in how social support was measured and defined across the included papers. In Paper 2 my co-authors and I explored the relationships between risk and protective factors for sibling psychosocial adjustment in a proposed family model. We found paternal mental health and parent-sibling communication quality to be associated with siblings' psychosocial adjustment. In Paper 3 my co-authors and I evaluated the initial outcomes of a manualized parent-sibling preventative intervention in a cluster randomized controlled trial (SIBS-RCT). The initial result showed no statistically significant effects. However, small effect sizes in favor of SIBS are promising for improvements in parent-sibling communication and sibling mental health and signals the need for further refinement of the program, to investigate mechanisms of effect and to target subgroups of siblings at heightened risk. Collectively, the result from the papers in this thesis stresses the importance of enhancing sibling social support, supporting parent-sibling communication and fathers’ roles in families with childhood chronic disorders as these factors may be important for sibling psychosocial adjustment. Suggested clinical recommendations include assessment of individual family members experiences and roles to better target sibling risk factors.

  Policing is widely recognised as one of the world’s most stressful occupations. Extensive research has examined the impact of organisational and operational stressors on police employees. Although this literature, largely focused on sworn officers, consistently identifies organisational stressors as particularly burdensome, the field remains dominated by studies of operational tasks. Comprehensive reforms aimed at addressing the increasingly complex criminality have underscored the need for specialised professionals. Civilians from diverse professional backgrounds are now recruited to perform roles previously reserved for sworn officers, introducing new stressors that remain largely unaddressed. Moreover, the field offers limited insight into stress as a broader phenomenon, due to inconsistent definitions, limited theoretical guidance, and substantial variability in methodology and measurement tools. This dissertation adopts a structured conceptualisation of stress grounded in two main perspectives: stimulus–response and cognitive appraisal, each with distinct methodological implications. In this dissertation, these perspectives are positioned at opposite ends of a continuum. Stimulus–response models understand stressors as objective conditions that elicit physiological, psychological, or behavioural responses. Cognitive appraisal models, in contrast, view stress as arising from individuals’ interpretations of internal or external demands, shaped by perceived coping capacity. Stress models are located along this continuum according to their theoretical proximity, making explicit the assumptions embedded in different measurement strategies and their analytical consequences. Across three empirical articles, the dissertation examines how stress is conceptualised and measured in policing, and how methodological choices affect the credibility, coherence, and interpretability of empirical findings. The first study maps and summarises instruments used to assess stress in police populations internationally. The second study, focusing on investigative interviewers, demonstrates the utility of a single item, appraisal-based stress measure and provides an empirical example of an alternative to more commonly used stimulus–response approaches. The third study analyses how the widely used Police Stress Questionnaire (PSQ) has been applied differently across studies. Collectively, the findings underscore that valid and reliable instruments yield meaningful results only when embedded in methodological frameworks consistent with their theoretical foundations. Few police-specific measurement instruments currently in use are updated to address emerging stressors. Closer alignment among theory, measurement, and analysis can promote more coherent and practice-oriented knowledge about stress in contemporary police work. The dissertation highlights the importance of context sensitive operationalisations and explicit specification of causal relationships between constructs and indicators. By systematically aligning theoretical positioning with measurement and analytical strategies, this work offers a foundation for more coherent, theoretically informed, and contextually relevant research on stress in contemporary policing.

  How do male supremacist online communities maintain social identification, even in the face of constant societal stigma and self-derogation? This study employs computational social science methods to examine the themes, group-level emotions and lexical strategies used to maintain social identification in Involuntary Celibate (incel) online communities. The findings reveal that the biological essentialism and inherent system justification of the “blackpill” ideology effectively block cognitive and behavioural exits and render collective social competition unavailable. This specific ideology-driven mechanism, which forces members of incel online communities to rely on social creativity and outgroup derogation to maintain positive distinctiveness, reflects both group boundary impermeability and system justification and will be referred to as “ideological impermeability.” The computational mapping of the emotional spectrum of the two analysed online communities also reveals a profoundly negative collective emotionality, both toward the outgroups and, surprisingly, toward the ingroup members, reinforcing the conclusion of chronically negative social identity maintained through outgroup derogation, social creativity and ideological impermeability that stops individual mobility and social action. Lastly, the low frequency of violent lexicon relative to the systemic dehumanization of outgroups further supports the hypothesis of reliance on passive social creativity and outgroup derogation, instead of violent collective action, challenging the common portrayals of incel communities as violent radicalisation hubs. A new view of the blackpill ideology as a structural barrier that denies the choice of change, and not just a set of extremist beliefs, is fundamental for the development of effective future deradicalization pathways.
