This study evaluated the Family Crisis Intervention Program (FCIP), focusing on crisis, child safety, family functioning and child behaviour problems. Questionnaires were completed by 183 families in crisis and their FCIP worker. After FCIP, the crisis had decreased and child safety had increased. Although problematic family functioning persisted after intervention, improvements were found in parent–child interaction, parenting stress, parental competence and child behaviour problems. Crisis change, safety change and improved family functioning were associated with programme characteristics, especially the therapeutic relationship, analysis of the crisis situation, duration of the intervention and the solution‐focused approach. The discussion addressed implications of this study with regard to outcome measures in the evaluation of family crisis intervention and the importance of particular programme characteristics.
