BackgroundLittle is known about the experiences of parents who are in receipt of in-patient psychiatric care or about what interventions are employed to support them in their parenting role.AimsThe objective of the current study is to review two complementary areas of research: (a) research examining interventions developed to support the parent–child relationship within these settings; and (b) research focused on the experience of parents in in-patient settings.MethodFor studies reporting on parents’ experience, qualitative accounts of past or present psychiatric in-patients (child aged 1–18 years) were included. For intervention studies, the intervention had to focus on supporting the parenting role and/or the parent–child dyad of parents (child aged 1–18 years) in current receipt of in-patient care. Four bibliographic databases (PubMed, SCOPOS, Web of Science and PsychINFO) were searched for relevant published and unpublished literature from 1 January 1980 to 26 July 2022. Intervention studies were appraised using the Mixed Methods Appraisal Tool. Qualitative papers were assessed using the Critical Appraisal Skills Programme tool. Data were extracted using tools designed for the study. Qualitative data were synthesised using thematic analysis. The protocol was registered with the International Prospective Register of Systematic Reviews (reference CRD42022309065).ResultsTwenty-four papers (eight intervention studies and 16 studies examining parent experience) were included in the review. In-patient parents commonly reported hospital admission as having a negative impact on their parenting. Very few robust reports of interventions designed to support parents in receipt of psychiatric in-patient care were found.ConclusionsDespite the identified need for support by parents who are receiving in-patient care, there is currently no intervention of this nature running in the UK health service.
