Guided by Communicated Narrative Sense-making Theory (CNSM), the current study investigated mental illness (MI) narratives told within families and the lessons younger members learned from these stories. Individual, semi-structured interviews with young adults (N = 24) revealed that family members, mainly parents, share stories about the MIs of individual family members and narratives reflected themes of struggle and caution. Participants reported learning important lessons from these MI narratives (i.e., MI awareness, importance of understanding MI). Findings illuminate the ways family narratives about MI teach younger members lessons and expectations for managing MI despite sometimes reinforcing MI stigma. Limitations, future directions, and implications for narrative interventions are also discussed.
