The aim of this study was to evaluate the usefulness of Family-Centered Support Conversations (FCSC) offered in community mental health care in Norway to young adults and their families experiencing mental illness. The FCSC is a family nursing intervention based on the Calgary Family Assessment and Intervention Models and the Illness Beliefs Model and is focused on how family members can be supportive to each other, how to identify strengths and resources of the family, and how to share and reflect on the experiences of everyday life together while living with mental illness. Interviews were conducted with young adults and their family members in Norway who had received the FCSC intervention and were analyzed using phenomenography. Two descriptive categories were identified: "Facilitating the sharing of reflections about everyday life" and "Possibility of change in everyday life." The family nursing conversations about family structure and function in the context of mental illness allowed families to find new meanings and possibilities in everyday life. Health care professionals can play an important role in facilitating a safe environment for young adults and their families to talk openly about the experience of living with and managing mental illness.
