Background: During child psychiatry hospitalization, working with the families or attachment figures is a challenge, most of the children who are admitted to these units come from multi-problem families, with limited research in this area. Video feedback (VF) interventions have proved to be a powerful resource to promote parental and child well-being in small children and has been used with parents with a psychiatric condition. Parental Reflective Functioning (PRF) is one of the parental abilities that can be improved with VF and could be especially important in coping with conflict and negative emotions in older children. The aim of this study is to implement Video Intervention Therapy (VIT) to enhance PRF in primary caregivers of inpatient psychiatric children. As there is no published research using VF with parents of children with severe psychopathology in a hospitalized context. This report, then, becomes a much needed pilot study providing evidence for a larger randomized control trial (RCT). Methods: The study is a single-center, two-arm feasibility randomized control trial with a qualitative component. Block randomization was done to generate a 2:1 allocation, leaving more participants in the intervention group. The intervention comprises four modules; every module has both one video-recorded play session and one VIT session (in a group setting) per week. Evaluation of the caregivers included assessments of PRF and well-being, and child assessment included parent-ratings and clinician-ratings of symptomatology and general functioning. Results: Thirty participants were randomized; eligibility and recruitment rate were 70.6% and 83.3%, respectively. The compliance-to-intervention rate was 85% in the VIT group and 90% in the control group. All participants completed entry evaluation and 90% at the 3-month follow-up. The intervention was acceptable to participants and feasible for therapists to deliver. Outcome data must be treated with caution due to the small numbers involved, yet indicate that the VIT may have a positive effect in improving parental and child mental health outcomes. Conclusions: VIT for primary caregivers of child inpatient children was feasible to deliver and acceptable for participants, therapist, and the staff unit involved; there is sufficient evidence to undertake a full-scale effectiveness RCT.
