Behavioral interventions for cancer survivors have historically targeted older adults or young adult survivors of childhood cancer. In this study, 18- to 39-year-olds diagnosed with cancer during young adulthood were interviewed to identify the types of behavioral and psychosocial programs needed. These young adult cancer survivors were also asked to identify potential barriers to program utilization. Participants expressed interest in programs targeting physical activity, relaxation, emotional support, provision of cancer-related and other information, and nutrition/weight loss. Emergent themes included the importance of choice, flexibility, convenience, and similarity to other program participants. Barriers to participation included practical barriers (e.g., limited time), lack of awareness of programs, health issues (e.g., fatigue), and psychosocial barriers (e.g., low motivation). Results highlight a range of unmet psychosocial and behavioral needs among young adult cancer survivors. This information can be used to develop interventions for this population.
