Purpose: Adolescent and young adult (AYA) cancer survivors' families can face ongoing challenges into survivorship. Families' adjustment and functioning as a unit can subsequently impact AYAs' mental health and quality of life. This study examined AYA cancer survivors' perceived family functioning, compared with their peers, and investigated factors associated with family functioning. Methods: Eligible participants were aged between 15 and 40 years, fluent in English, and cancer survivors who had completed treatment. AYA cancer survivors were recruited from hospital clinics, and the comparison group from an affiliated university campus. Participants completed the McMaster Family Assessment Device, Kidcope, and the Depression, Anxiety and Stress Scale-Short Form. We analyzed between-group differences in family functioning using multivariate analysis of covariance and used partial correlations to investigate associations between demographic cancer-related psychological coping variables and family functioning. Results: Ninety-three AYA cancer survivors and 141 comparison peers participated (ages: 15-32 years). AYA cancer survivors reported significantly better family functioning (p = 0.029), lower depression (p = 0.016), and anxiety symptoms (p = 0.008) compared with the comparison group. Approximately one-third of AYA survivors (34.4%) reported clinically significant maladaptive family functioning; however, this was more prevalent in the comparison group (50.4%). After adjusting for covariates, poorer family functioning was associated with AYA survivors using more avoidant escape-oriented coping strategies (p = 0.010). Conclusions: Our cancer survivor cohort reported better family functioning and psychological outcomes compared with their peers. Interventions targeting avoidant coping behaviors may support improved family functioning in some survivors. Further research disentangling the relationship between coping mechanisms and family functioning among AYA cancer survivors is needed.
