Family functioning is often impaired in families with a parent with mental illness and is linked to child mental health. This study aims to gain a better understanding of family functioning in affected families by comparing ratings among family members and by analyzing associations with clinician-rated family functioning. The cross-sectional sample comprised 210 families with ratings of 207 patients, 139 partners, and 100 children. Parents with a mental illness as well as their partners and children completed the German version of the Family Assessment Measure (FAM). Clinician ratings were obtained by the Global Assessment of Relational Functioning Scale (GARF). We conducted several mixed models to compare ratings of family functioning while accounting for family cluster. Family dysfunction was consistently elevated compared to a normative sample. On several domains, parents with a mental illness perceived family functioning to be worse compared to their partners and children. Partners and children did not differ in their perceptions of family functioning. Ratings of family members were moderately associated with clinician ratings. We discuss the importance of multi-informant assessment of family functioning and the implementation of family-based interventions for families with a parent with mental illness.

Offspring of mentally ill parents is at heightened risk for psychological symptoms. The identification of environmental factors that predict their mental health is crucial for the development of preventive and therapeutic measures. In the current study, we addressed the combined role of family functioning and social support by taking mentally ill patients’, their partners’, and children’s perspectives into account. The cross-sectional sample included n=195 families (195 patients, 127 partners, and 295 children). Family members completed questionnaires related to family functioning, social support as well as parental and child psychopathology. We conducted multilevel analyses to investigate the associations with internalizing and externalizing problems in children. Family functioning and social support were significantly associated with child internalizing and externalizing problems. However, results varied depending on the rating perspective. We found significant interaction effects of family functioning and social support on child psychopathology. The findings point to the importance of family functioning and social support as potential targets for interventions. Findings should be replicated in future longitudinal studies.

Background: Children of parents with mental illness have a higher risk of developing mental health problems when compared with the general population. Therefore, families with parents with mental illness are a suitable target group for selective prevention. In order to plan and evaluate the health economic consequences of preventive interventions for this target group, data on the societal costs related to parenthood under the condition of mental disorders are needed. To date, within Germany there has been a lack of research evaluating the costs of mental health treatment and use of social services by children and adolescents with parents with mental illness. Methods: As part of a multicentre randomised controlled trial, use and costs of health and social services were assessed for a sample of 332 children and adolescents with parents with mental illness in six regions of Germany. Service use at baseline was assessed by the German version of the Children and Adolescent Mental Health Service Receipt Inventory. Costs were calculated for 12 months based on diagnosis and service user status and described separately. Cost drivers were identified by means of a two-part regression model. Results: Total mean costs for 12 months for the total sample amount of € 3736.35 (95% CI: € 2816.84–4813.83) per person. Children with a psychiatric diagnosis generated a total of € 5691.93 (95% CI: € 4146.27–7451.38) of costs per person, compared to € 1245.01 (95% CI: € 657.44–1871.49) for children without a psychiatric diagnosis. The logit part indicates significant odds ratios for individual functioning and diagnosis of the child as well as for family functioning. The linear part reveals that increasing individual functioning in the child is related to decreasing costs. Conclusions: Children of families with parents with mental illness use a broad spectrum of mental health care, school-based support and youth welfare services even if they are not yet diagnosed as having a mental disorder. Further research should examine whether these institutions are sufficiently qualified and interlinked to meet the support needs of this vulnerable group. Trial registration The study was registered at the 07/10/2014 before the start of data collection (04/11/2014) at the German clinical trials register (Deutsches Register Klinischer Studien, DRKS, nr: DRKS00006806, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00006806).

Children of mentally ill parents represent a particularly vulnerable risk group for the development of mental illness. This study examines whether there is a predictive association between children’s psychiatric symptomatology and (1) the clinical diagnosis according to the International Statistical Classification of Diseases and Related Health Problems (ICD-10) of their mentally ill parent as well as (2) to families both parents showing psychiatric symptoms. The study is part of the multicenter controlled trial project “Children of Mentally Ill Parents” (CHIMPS). For this purpose, the psychiatric symptomatology of the mentally ill parent (N = 196) and his or her partner (N = 134) as well as the psychiatric symptomatology of their children aged 4 to 18 years (N = 290) was measured using clinical rated ICD-10-diagnosis, self-rated Brief Symptom Inventory (BSI), and Child Behavior Checklist (CBCL). Using multilevel analyses, the severity of the parental psychiatric symptomatology (BSI) was identified as a significant predictor of children’s psychiatric symptomatology (CBCL). Children of parents with a personality disorder (ICD-10) were not more affected than children of parents with another ICD-10-diagnosis. However, children with two parents showing psychiatric symptoms (CBCL) were significantly more affected than children with one mentally ill parent. The results of this study support the well-known view that parental mental illness is a risk factor for children’s psychiatric symptoms. Therefore, increased support, especially in high-risk families, both parents having psychiatric symptoms, is highly necessary and should be implemented in the future psychotherapeutic family care.
