Development and initial testing of TOGETHER-YA: an eHealth-delivered and group-based psychosocial intervention for young adult cancer survivors.

PURPOSE: This study aimed to (1) develop TOGETHER-YA, an e-Health-delivered and group-based health-related quality of life (HRQOL) intervention for young adult (YA) cancer survivors aged 18-39 (Part 1), and (2) determine its initial feasibility and acceptability in a single-arm pilot trial (Part 2). METHODS: TOGETHER-YA is a manualized, 10-week intervention for YA survivors that includes elements of relaxation training, cognitive-behavioral therapy, and health education. In Part 1, content was adapted from existing evidence-based interventions with feedback from YAs (N = 22) in four iterative focus groups. In Part 2, YA survivors (N = 11) participated in a single-arm pilot trial of TOGETHER-YA. Intervention groups were led by a trained facilitator over videoconference. Primary outcomes were feasibility (i.e., recruitment, session attendance, retention) and acceptability (i.e., participant satisfaction). RESULTS: Focus groups reacted positively to TOGETHER-YA and provided actionable recommendations for enhancing its relevance and acceptability, which were implemented. In initial testing, all feasibility and acceptability benchmarks were met; 58% of eligible YAs were recruited, participants attended M = 6 intervention sessions (SD = 3), and 82% of participants were retained post-intervention. On average, participants "agreed" to "strongly agreed" with positive statements about the weekly sessions and the overall program. CONCLUSION: TOGETHER-YA was developed in collaboration with YA cancer survivors and found to be feasible and acceptable in initial testing. TOGETHER-YA is the first HRQOL intervention for a broad range of YA survivors that is eHealth-delivered for convenience and group-based for peer support. Future large-scale trials should test its efficacy for improving HRQOL. TRIAL REGISTRATION: NCT05048316, September 17, 2021; NCT05054569, September 23, 2021.
