12005 Background: Young adults (YAs) diagnosed with cancer between the ages of 18 and 39 face unique psychosocial challenges and are at risk of experiencing significant emotional distress and poor health-related quality of life (HRQOL). This randomized trial evaluated the efficacy of Bright IDEAS-YA, a problem-solving skills training intervention, on reducing distress and improving HRQOL of YAs newly diagnosed with cancer. A secondary aim examined change in problem-solving ability as a potential mediator of treatment effects. Methods: A three-site randomized trial of Bright IDEAS-YA compared with enhanced usual care (EUC) enrolled YA survivors within four months of a first diagnosis of cancer. Participants were randomized 1:1 to Bright IDEAS-YA or EUC (NCT04585269). Bright IDEAS-YA is a 6-session, one-on-one intervention that teaches a systematic approach to overcome personal challenges across any life domain. EUC involved usual psychosocial care plus AYA resources. Participants completed surveys at 0 (baseline), 3, 6, 12, and 24 months, with 6 months as the primary endpoint. Validated measures included the PROMIS Depression Short Form and Anxiety Short Form (primary outcomes), the Functional Assessment of Cancer Therapy – General (FACT-G; primary outcome), and Social Problem-Solving Inventory-Revised Short Form (SPSI-R; mediator). Efficacy was tested using linear mixed effects models, run in R, examining the group x time interaction effects. Mediation was tested using the R multiple mediation analysis. Results: 344 YA (34.2% acceptance rate, M age = 30.3 years, SD = 6.3; 63% female, 37% male, < 1% non-binary) participated (100% planned enrollment), with 86% and 81% completing surveys at 3 and 6 months, respectively. Compared to baseline, the intervention arm showed statistically significant improvements in depression, anxiety, and HRQOL relative to the control group at 6 months. The intervention arm demonstrated an average reduction of 3.2 T-score points reduction in depression (95% CI [-4.9, -1.5], p < 0.001), 2.4 T-score points in anxiety (95% CI [-4.0, -0.81], p = 0.003), and 3.4 points improvement in total FACT-G (95% CI [0.34, 6.5], p = 0.029) relative to the control. These differences reflect clinically meaningful changes per published reports. Across all three models, change in total problem-solving ability (SPSI-R) was shown to mediate treatment effects, primarily due to change in the negative problem-orientation subscale. Conclusions: Bright IDEAS-YA was efficacious in reducing symptoms of depression and anxiety and improving HRQOL compared with enhanced usual care among YAs with cancer. Improvements are attributable to increased problem-solving ability, particularly by reducing the tendency to view problems as significant threats and doubt one’s ability to successfully solve problems.
