Preventive interventions for children of parents with depression, anxiety, or bipolar disorder: A quasi-experimental clinical trial

Summarising Quantitative Outcomes in Parental Mental Illness Research

A quarter of all children grow up in a family where a parent experiences a mental illness (FaPMI). Research activity in this area is growing rapidly and it is now critical to better understand the extant knowledge in the field. This scoping review of quantitative FaPMI literature parallels a qualitative literature review and a series of Delphi studies with key stakeholders (e.g. lived experience and clinicians), that is part of a larger program of research to achieve consensus regarding the direction of FaPMI research; including making recommendations about outcomes and measures. The programme of research aims to promote and facilitate greater comparison and learning across studies and settings. Initially this scoping review summarises the quality and focus (e.g. country and sampling) of 50 quantitative studies from 2000 to 2023 and then classifies studies according to outcomes for parents, children and families. Six to eleven years were the most common child sample group and girls were slightly underrepresented (49/51) and parents were 88% mothers. Analogous parent and child outcomes were; mental illness/psychopathology, wellbeing, mental health literacy, trauma and stressful experiences, coping, help seeking/service need, within family relationships and supports, outside family relationships and supports. Additional outcomes for parents were; parenting skills, parent competence and parenting stress and for children in relation to their; cognitive functioning and caregiving. The family related outcomes were the within and outside family relationships and supports. Since 2000 there have been 136 different survey instruments employed with approximately 80% used in only one study. This suggests that the broader goals of the program of research are warranted as there is a need for less heterogeneity in measures used. Suggested areas for future research include a sampling focus on fathers, economic evaluations of programs, parent mental health literacy, trauma, genetics and integrating well-being concepts into research designs. Child research should focus on mental health literacy, the level and impact of caring responsibilities, assessing past trauma and the roles of close family and external supports.

Family Talk versus usual services in improving child and family psychosocial functioning in families with parental mental illness: a randomised controlled trial and cost analysis

Background

Parental mental illness (PMI) is common and places children at high risk of developing psychological disorders. Family Talk (FT) is a well-known, whole-family, 7-session intervention designed to reduce the risk of transgenerational psychopathology. However, very few larger-scale evaluations of FT (across only a limited number of settings) have been conducted to date while there have been no cost analyses. This study aimed to assess the effectiveness and costs of delivering FT in improving child and family psychosocial functioning in families with PMI within routine mental health settings.

Methods

A total of 83 families with PMI, with children aged 5-18 years, were randomly assigned on a 2:1 ratio to receive either the FT intervention (n=55 families) or usual services (n=28 families) across 10 adult, child and primary care mental health sites in Ireland. Parental disorders included anxiety/depression (57%), Bipolar Disorder (20%), Borderline Personality Disorder (12%), Post-Traumatic Stress Disorder (8%) and psychosis (2%). Detailed assessments with parents were conducted at baseline and 6-month follow up.

Results

FT led to significant improvements in family functioning and child behaviour at 6-month follow up when compared to usual services, with medium effect sizes indicated. Parent participants with lower mental health literacy at baseline also showed significant post-intervention improvements. Those parents with less severe mental illness at baseline, and families with more partner and economic supports, reported additional significant post-intervention improvements in child depression/anxiety and parental mental health symptoms. The cost of FT amounted to €761.50 per family, although this decreased to €415.31 when recurring costs only were included.

Conclusion

The findings from this study, which was conducted within the context of a national programme to introduce family-focused practice in Ireland, demonstrate that FT is a low-cost intervention that improved child and family psychosocial functioning across different mental health disorders within routine adult, child and primary care mental health services. The findings contribute to the growing evidence base for FT, and provide a robust basis to inform practice and policy development for families with parental mental illness both in Ireland and elsewhere.

'Let's Talk About Children' family focused practice for children of parents with schizophrenia and bipolar disorder: protocol for a randomized controlled trial

INTRODUCTION

'Let's Talk About Children' is a brief family focused intervention developed to improve mental health outcomes of children of parents with mental illness (COPMI). This study aims to assess the efficacy of LTC in improving mental health of children of parents with schizophrenia or bipolar disorder in China.

METHODS

The planned study is a multicentre parallel group randomized wait-list controlled trial. A total of 400 eligible families with children aged 8 to 18 years will be recruited, 200 each for families with parental schizophrenia or bipolar disorder. The intervention group will receive Let's Talk About Children delivered by a trained therapist, while the control group will receive treatment as usual. The primary outcomes are child mental health measured by the strengths and difficulties questionnaire and parent-child communication measured using the parent-adolescent communication scale. Parental mental health and family functioning are secondary outcomes. This study also plans to explore mediating factors for the effect of Let's Talk About Children on child mental health, as well as conduct a cost-effectiveness analysis on using Let's Talk About Children in China.

CONCLUSION

The present study will provide evidence for the efficacy of Let's Talk About Children in families with parental schizophrenia and bipolar disorder in China. In addition, it will evaluate potential mechanisms of action and cost-effectiveness of Let's Talk About Children, providing a basis for future implementation.
