Mixed-method examination of factors associated with adolescent decision-making and involvement in care in the context of advanced cancer

Objectives: Adolescents with cancer often experience significant symptom burden and aggressive treatment near end-of-life. Increased adolescent involvement in care and decision-making may benefit health outcomes. Limited research has examined factors associated with adolescents' involvement in care in the context of advanced disease. Thus, we examined the impact of background factors and decision-making perceptions on both adolescents' involvement in care and their desired change in involvement. Methods: Adolescents with advanced cancer (<60% survival or refractory/relapsed disease), ages 10-23 (n = 41; M-age = 15.37), were recruited approximately 1 month after diagnosis to complete measures of decision-making perceptions and their family role. Hierarchical regressions examined the contributions of background factors and decision-making perceptions to adolescents' frequency and desired involvement in their care. Qualitative interviews regarding decision-making were analyzed using deductive analysis. Results: The model examining frequency of involvement in care was significant, F(5,34) = 3.12, p = .02, R-2= .31. Older age was the only significant predictor (beta = .13, p= .003). The model examining desired involvement was non-significant, F(5,34) = 2.22, p = .075. Qualitative analysis indicated that (1) older adolescents have more involvement in decision-making, (2) collaborative decision-making occurred between the adolescent and extended family, and (3) adolescents trusted others to make decisions. Integration of qualitative and quantitative data revealed congruence in findings. Significance of results: Adolescents with advanced cancer, who consider how decisions directly impact them and prefer greater autonomy, may be more involved in their medical care. Research is needed to identify other longitudinal predictors of decision-making and involvement in care. Providers should consider encouraging families to communicate their preferences and engage in shared decision-making.
