- Expectations held by foster caregivers compared to the reality of their experiences July 31, 2026The experiences foster caregivers have while providing care are linked to important outcomes including placement stability for the child and foster caregiver retention within the child welfare system. Understanding the expectations prospective caregivers have about fostering, and how this compares to their lived experience while fostering, is important for building realistic expectations and addressing unmet […]Gina J Chan
- ADHD and Student Grades in Children from the ABCD Study<sup>®</sup>: A Twin and Siblings Study July 24, 2026Attention-deficit/hyperactivity disorder (ADHD) symptoms are strongly associated with lower academic performance, yet the nature of this association remains uncertain. We analyzed data from twins and siblings in the Adolescent Brain Cognitive Development (ABCD) Study^(®) to examine the relationship between ADHD symptoms and school grades using genetically informed models. ADHD symptoms were assessed via the Child […]Luis F S Castro-de-Araujo
- Elucidating psychosocial outcome profiles as a function of aggregate genetic risk for suicide attempt and alcohol use disorder July 10, 2026Genetic factors contribute to alcohol use disorder (AUD) and suicide attempt (SA) co-occurrence. Whether individuals with high genetic liability to one outcome versus the other, or to both, differ in terms of their risk for other psychosocial outcomes is unexplored. To this end, the authors conducted a cohort study of Swedish individuals born 1965-1985, with […]Alexis C Edwards
- Effects of family genetic risk scores and environmental factors on risk of schizophrenia and bipolar disorder July 3, 2026Both genetic and environmental risk factors contribute to the development of schizophrenia (SCZ) and bipolar disorder (BD), but simultaneous investigation of how these factors influence risk has not yet been comprehensively examined in a large population. Therefore, we aimed to investigate and quantify how a multi-generational index of aggregated genetic risk (family genetic risk scores, […]Natassia Robinson
- Predictors of Mental Healthcare Need and Utilisation Among Asian American Adolescents With Intellectual and Developmental Disabilities July 2, 2026CONCLUSION: Adolescents with I/DD in the United States experience racial/ethnic disparities in mental healthcare. The findings from this suggest the need to investigate further into the intersection of race/ethnicity and I/DD in mental healthcare and the creation of policies that promote equitable access to mental healthcare services for adolescents with I/DD, especially for minority individuals.Kayla K Van
- LT-FGRS: a unifying R-package for the estimation of family-based genetic liabilities at population-scale June 29, 2026Estimates of per-individual genetic liability from large-scale family data are routinely used in biomedical research to describe genetic etiology of traits and disorders, boost the power of gene-mapping studies, and improve risk predictions. Here we present LT-FGRS, an R package for handling population-scale pedigrees and implementing multiple state-of-the-field methods for estimating genetic liability from such […]Emil M Pedersen
- Can We Improve the Prediction of Early Onset Mania and Hypomania in the Community? June 26, 2026CONCLUSIONS: Improving the accurate prediction of BD onset would benefit from greater consensus regarding the operationalisation of known risk attributes and selection of analytic models that consider sample imbalances.Jan Scott
- Co-expression-based models improve eQTL predictions for transcriptome-wide association studies and highlight new schizophrenia-associated genes June 22, 2026Most genetic variants associated with complex heritability phenotypes lie in non-coding regions and are thought to influence disease risk by regulating gene expression. However, most transcriptome-wide association approaches primarily model local (cis) genetic effects, leaving much of gene regulation unexplained. Here, we show that incorporating distal (trans) regulatory effects improves the prediction of gene expression […]Fabiana Rossi
- High Prevalence of Suicidal Behavior in Severe Alcohol Use Disorder Linked to Specific Neurocognitive Deficits: The Cognition, Alcohol, Genes, and Environment Study June 19, 2026CONCLUSIONS: These preliminary findings open research avenues to study the mechanisms related to the co-occurrence of AUD and STB, with the hope of reducing STB risk in this population.Séverine Lannoy
- Leveraging Family Genetic Risk Scores to Understand the Etiology of Suicidal Behaviors and Their Associations With Psychiatric Disorders June 19, 2026CONCLUSIONS: Though psychiatric disorders were associated with increased risk of SA/SD, a substantial proportion of suicidal behaviors occurred outside the context of psychiatric disorders, urging the development of screening and prevention in non-psychiatric populations. Despite their low genetic liability for SA/SD, findings suggest that the effect of genetic risk on SA/SD risk is stronger in […]Séverine Lannoy
- Changes in Genetic Contributions to ASD and ADHD by Year of Diagnosis June 10, 2026CONCLUSIONS AND RELEVANCE: By analyzing multiple polygenic scores together with simulated expectations, this study could disambiguate among competing hypotheses about scenarios that may be associated with increased rates of ADHD and ASD diagnoses. Findings support broadening diagnostic criteria as an explanation for increasing rates, with implications for understanding changes in risk factors and clinical practice.Sonja LaBianca
- Predicting Functional Changes in Down Syndrome During the COVID-19 Pandemic: The Role of Biopsychosocial Determinants of Health June 4, 2026CONCLUSIONS: Mental health and healthcare access barriers were biopsychosocial correlates of functional changes for people with DS during COVID-19.Ester Jo
- Social Media Usage and Its Association With the Social Media Addiction Questionnaire Scale Among Early Adolescents June 1, 2026CONCLUSION: Higher SMA scores were most associated with TikTok, Instagram, and Snapchat use as well as using a public account, a secret account, and spending more time on social media. The relationship between social media hours and SMA confirms previous findings. This is the first study to investigate the relationship between account settings and SMA.Jacob C Hermann
- Shared genetic risk between functional somatic syndromes, internalizing disorders, and immune-mediated diseases: a twin-sibling study May 26, 2026Functional somatic syndromes frequently co-occur with internalizing disorders such as anxiety disorders and major depressive disorder. Both show familial associations with immune-mediated diseases. Here, we estimate genetic and environmental contributions to functional somatic syndromes and their overlap with immune-mediated diseases, with internalizing disorders included for comparison. The study sample consisted of 6,097,372 Swedish twins, full […]Olivier D Steen
- Structure of the Genetic Risks for Psychiatric Disorders in Swedish Population-Based Registries May 20, 2026CONCLUSIONS AND RELEVANCE: Using a complete epidemiological ascertainment frame for treated psychiatric disorders in a large population sample with high-quality registries, this cohort study uncovered a structure of genetic risks that, compared to prior efforts, was similar in many ways but also had important differences.Kenneth S Kendler
- The typology of common psychiatric disorders as depicted by genetic maps: a study based on Swedish population-based registers May 15, 2026We sought to clarify the inter-relationships among a range of psychiatric and substance use disorders by employing two-dimensional genetic maps, with axes defined by family genetic risk for major depression (MD) and drug use disorder (DUD). Using comprehensive Swedish national register data, we located cases of 12 disorders within this space and examined how their […]Kenneth S Kendler

Five APN projects are participating in the current study […]Ana M Diaz-Zuluaga
- Predicting the geographical distribution of drug use disorder in Sweden from the geographical variation in social deprivation, genetic risk and urbanization May 11, 2026Drug use disorder (DUD) is distributed unevenly over geographical areas of Sweden. We explore, using geographically weighted regression, the proportion of this variation associated with community levels of genetic risk, social deprivation and urbanicity. In the 5983 Demographic Statistical areas (DeSOs) within Sweden, we predict DeSO prevalence from mean genetic risk for DUD, measured by […]Kenneth S Kendler
- Adolescent music engagement is associated with less alcohol consumption and substance experimentation 5-11 years later: A genetically informative study May 7, 2026CONCLUSIONS: Music engagement is associated with reduced substance use in adolescence and young adulthood, driven by protective shared environmental influences rather than direct effects. Music engagement may represent a constructive environmental outlet for youth, underscoring the importance of genetically informed research. However, the results may not generalize to more contemporary and/or diverse cohorts. (PsycInfo Database […]Lydia Rader
