War and military crises can disrupt family mental health, cohesion, relationships, and functioning. Despite growing attention to family resilience, qualitative evidence on how resilience is strengthened within the Iranian cultural context remains limited. This study aimed to explain family resilience enhancement strategies during wartime crises based on the lived experiences of Iranian parents. This qualitative study employed Braun and Clarke’s reflexive thematic analysis. Participants were 20 parents residing in Isfahan, Iran, who had experienced the 12-day military conflict in 2025. Purposive sampling continued until data saturation was reached. Data were collected through semi-structured interviews and analyzed using the six-phase thematic analysis process. Trustworthiness was enhanced through member checking, researcher agreement, an audit trail, and expert review. Eight overarching themes emerged: family emotional and psychological regulation, cognitive crisis management, strengthening family functioning, supporting children, managing daily life during crisis, mobilizing social resources, reinforcing shared identity and values, and outcomes of enhanced family resilience. The findings indicated that resilience develops through the interaction of emotional, cognitive, familial, social, and cultural strategies and is associated with reduced psychological distress, stronger family cohesion, enhanced social support, greater perceived control, and post-crisis growth. Family resilience during wartime is a dynamic, multidimensional, and context-dependent process shaped by the synergistic use of individual, familial, social, and cultural resources. The findings may provide an evidence-informed basis for developing family-centered interventions, psychological preparedness programs, and mental health policies aimed at strengthening families during future crises and strengthening adaptive capacity across changing and prolonged crisis conditions.
