Effects on family functioning and the home environment of a family-based preventive intervention for children of parents with severe mental illness: A randomized controlled trial.

Objective: Children of parents with severe mental illness are at increased risk of mental illness throughout their lifespan due to complex gene-environment interactions. Preventive interventions supporting parents and children are warranted. Compared with usual treatment, we tested the effectiveness of a multidisciplinary family-based preventive intervention, VIA Family.

Protocol for a systematic review with meta-analysis and trial sequential analysis of preventive interventions versus any control intervention for parents with a mental disorder on offspring outcomes.

Background: Offspring of parents with a mental disorder are at high risk of a range of adverse outcomes, highlighting the need for preventive interventions. However, a comprehensive overview of the beneficial and harmful effects of preventive interventions for parents with mental disorders on offspring outcomes are uncertain. The main objective of this systematic review will be to assess the effects of preventive interventions versus any control intervention for parents with a mental disorder on offspring outcomes.

Language, Motor Ability and Related Deficits in Children at Familial Risk of Schizophrenia or Bipolar Disorder.

Background: It is known that impairments in linguistic ability and motor function tend to co-occur in children, and that children from families with parental mental illness such as schizophrenia tend to perform poorly in both domains, but the exact nature of these links has not yet been fully elucidated.

Design: In this study, we leveraged the first wave of the Danish High Risk and Resilience Study (VIA 7), which includes both genetic data and measures covering multiple developmental domains. The VIA 7 cohort comprises 522 7-year-old children born to parents with schizophrenia (N = 202), bipolar disorder (N = 120) or neither (N = 200).

Family-based preventive intervention for children of parents with severe mental illness: A randomized clinical trial.

Background: Children of parents with a severe mental illness have an increased risk of developing a lifetime mental illness. We aimed to compare the effects of a preventive family-based intervention, VIA Family, with treatment as usual (TAU) on these children's global functioning.

Methods: Between 2017 and 2021, we conducted a pragmatic, rater-blinded, two-arm parallel-group superiority trial in Denmark.

Brain Activation and Aberrant Effective Connectivity in the Mentalizing Network of Preadolescent Children at Familial High Risk of Schizophrenia or Bipolar Disorder.

Background: Schizophrenia and bipolar disorder are characterized by social cognitive impairments, and recent research has identified alterations of the social brain. However, it is unknown whether familial high risk (FHR) of these disorders is associated with neurobiological alterations already present in childhood.

Methods: As part of the Danish High Risk and Resilience Study-VIA 11, we examined children at FHR of schizophrenia (n = 121, 50% female) or bipolar disorder (n = 75, 47% female) and population-based control children (PBCs) (n = 128, 48% female).

Comparing cognition in parents with schizophrenia or bipolar disorder and their 7-year-old offspring.

Individuals with schizophrenia (SZ) or bipolar disorder (BP) display cognitive impairments, while their first-degree relatives perform at an intermediate level between the patient groups and controls. However, the environmental impact of having an ill relative likely varies with the type of kinship and some studies suggest that offspring may be particularly disadvantaged. The present study aimed to investigate the relationship between parent and child cognition in parents with SZ or BD and their 7-year-old offspring.

Post-traumatic Stress Disorder in School-age Children: A Nationwide Prospective Birth Cohort Study.

Traumatic childhood events are some of the few identifiable and to some extent preventable causes of psychiatric illness. Children exposed to severely stressful events may react with post-traumatic stress disorder (PTSD) and this may impact their level of function in daily life, their future development and mental health. The traumatic stress model suggests that traumatic stress in the family, community violence, and other traumas are regarded as additive environmental factors that can outweigh protective compensatory factors and thus interact with individual vulnerabilities.

Clinical illness course and family-related outcomes among parents with a first episode of schizophrenia spectrum disorder: a 20-year follow-up of the OPUS trial.

Background: Studies investigating parenthood and how it affects long-term outcomes are lacking among individuals with schizophrenia spectrum disorders. This study aimed to examine the life of participants 20 years after their first diagnosis with a special focus on parenthood, clinical illness course, and family-related outcomes.

Methods: Among 578 individuals diagnosed with first-episode schizophrenia spectrum disorder between 1998 and 2000, a sample of 174 participants was reassessed at the 20-year follow-up.

Association of maternal and paternal personality disorders with risk of mental disorders in children: A nationwide, register-based cohort study of 1,406,965 children.

Background: Knowledge of the association between parental personality disorders and mental disorders in children is limited. To examine the association between parental personality disorders and the risk of mental disorders in offspring.

Methods: We linked Danish health registers to create a cohort of children born from January 1, 1995, to December 31, 2016.

Executive Control and Associated Brain Activity in Children With Familial High-Risk of Schizophrenia or Bipolar Disorder: A Danish Register-based Study.

Background And Hypotheses: Impaired executive control is a potential prognostic and endophenotypic marker of schizophrenia (SZ) and bipolar disorder (BP). Assessing children with familial high-risk (FHR) of SZ or BP enables characterization of early risk markers and we hypothesize that they express impaired executive control as well as aberrant brain activation compared to population-based control (PBC) children.

Study Design: Using a flanker task, we examined executive control together with functional magnetic resonance imaging (fMRI) in 11- to 12-year-old children with FHR of SZ (FHR-SZ) or FHR of BP (FHR-BP) and PBC children as part of a register-based, prospective cohort-study; The Danish High Risk and Resilience study-VIA 11.

Pubertal timing, sex hormone levels, and associations between early life adversity and accelerated development amongst 11-year-old children of parents with schizophrenia or bipolar disorder and controls: The Danish high risk and Resilience study via 11.

Background: Children of parents with severe mental illness have several known risk factors for altered pubertal timing. Pubertal timing is important for children's physical and emotional development. We aimed to examine pubertal timing and associations between pubertal timing, early life adversity and child problem behavior including psychiatric diagnoses among children of parents with schizophrenia or bipolar disorder and controls.

Children at Familial High risk of Schizophrenia and Bipolar Disorder Exhibit Altered Connectivity Patterns During Pre-attentive Processing of an Auditory Prediction Error.

Background And Hypothesis: Individuals with schizophrenia or bipolar disorder have attenuated auditory mismatch negativity (MMN) responses, indicating impaired sensory information processing. Computational models of effective connectivity between brain areas underlying MMN responses show reduced connectivity between fronto-temporal areas in individuals with schizophrenia. Here we ask whether children at familial high risk (FHR) of developing a serious mental disorder show similar alterations.

Home environment of 11-year-old children born to parents with schizophrenia or bipolar disorder - a controlled, 4-year follow-up study: The Danish High Risk and Resilience Study - VIA 11.

Background: The home environment has a major impact on child development. Parental severe mental illness can pose a challenge to the home environment of a child. We aimed to examine the home environment of children of parents with schizophrenia or bipolar disorder and controls longitudinally through at-home assessments.

Attachment representations in 7-year-old children at familial high risk of schizophrenia or bipolar disorder: Associations with mental disorders and daily functioning: The Danish High Risk and Resilience Study, VIA 7-A population-based cohort study.

Background: Attachment quality may affect psychological functioning. However, evidence on attachment representations and their correlates in children born to parents with schizophrenia and bipolar disorder is sparse.

Methods: We compared attachment representations in a Danish sample of 482 children aged 7 years at familial high risk of schizophrenia, bipolar disorder, and population-based controls and examined associations between attachment and mental disorders and daily functioning.

A study protocol for the randomized controlled trial SAFIR FAMILY TALK: a selective primary preventive intervention vs. service as usual for children of parents with mental illness.

Background: Children of parents with mental illness have an increased risk of developing mental illness themselves throughout their lifespan. This is due to genetic factors but also environmental disadvantages during childhood associated with parental mental illness. Selective primary preventive interventions for the children are recommended to mitigate risk factors and strengthen protective factors, but large-scale, longitudinal studies are needed.

Working memory heterogeneity from age 7 to 11 in children at familial high risk of schizophrenia or bipolar disorder- The Danish High Risk and Resilience Study.

Background: Despite the genetic overlap between bipolar disorder and schizophrenia, working memory impairments are mainly found in children of parents with schizophrenia. However, working memory impairments are characterized by substantial heterogeneity, and it is unknown how this heterogeneity develops over time. We used a data-driven approach to assess working memory heterogeneity and longitudinal stability in children at familial high risk of schizophrenia (FHR-SZ) or bipolar disorder (FHR-BP).

Mental Health Is a Family Affair-Systematic Review and Meta-Analysis on the Associations between Mental Health Problems in Parents and Children during the COVID-19 Pandemic.

As a multidimensional and universal stressor, the COVID-19 pandemic negatively affected the mental health of children, adolescents, and adults worldwide. In particular, families faced numerous restrictions and challenges. From the literature, it is well known that parental mental health problems and child mental health outcomes are associated.

Social responsiveness in families with parental schizophrenia or bipolar disorder-The Danish High Risk and Resilience Study.

Schizophrenia and bipolar disorder are highly heritable severe mental disorders associated with social impairments. Moreover, partners to individuals with one of these disorders display poorer functioning and more psychopathology, but their social skills and the transgenerational transmission remains uninvestigated. Therefore, we aimed to examine social responsiveness in families with parental schizophrenia or bipolar disorder.

The development in rating-based executive functions in children at familial high risk of schizophrenia or bipolar disorder from age 7 to age 11: the Danish high risk and resilience study.

Executive functions (EF) deficits are well documented in children at familial high risk of schizophrenia (FHR-SZ), and to a lesser degree in children at familial high risk of bipolar disorder (FHR-BP). The aim of this study was to assess EF development in preadolescent children at FHR-SZ, FHR-BP and population-based controls (PBC) using a multi-informant rating scale. A total of 519 children (FHR-SZ, n = 201; FHR-BP, n = 119; PBC, n = 199) participated at age 7, at age 11 or at both time points.

Affective lability in parents with schizophrenia or bipolar disorder and their co-parents - The Danish High Risk and Resilience Study VIA 7.

In bipolar disorder, dysregulation of affect is a core feature while knowledge on affective lability in schizophrenia is sparse. Research on affective lability in partners to individuals with schizophrenia or bipolar disorder is also lacking. The objective of this study was to investigate affective lability in parents with schizophrenia or bipolar disorder, and their co-parents without these disorders.

Associations between exposure to early childhood adversities and middle childhood psychotic experiences in children at familial high risk of schizophrenia, bipolar disorder, and population-based controls: The Danish high risk and resilience study - VIA 7 and VIA 11.

Background: Exposure to adversities in early childhood is associated with psychotic experiences and disorders in adulthood. We aimed to examine whether early childhood adversities are associated with middle childhood psychotic experiences in a cohort of children at familial high risk of schizophrenia (FHR-SZ), bipolar disorder (FHR-BP) and population-based controls (controls).

Methods: Four hundred and forty-six children from The Danish High Risk and Resilience Study - VIA7 and VIA11 participated in this study (FHR-SZ = 170; FHR-BP = 103; controls = 173).
