RecruitingBehavioural interventionA Biobehavioral Intervention to Reduce Adverse Outcomes in Young Adult Testicular Cancer SurvivorsThis study is a randomized controlled biobehavioral efficacy trial designed to investigate the feasibility and acceptability of a novel intervention, Goal-focused Emotion-Regulation Therapy (GET) aimed at improving distress symptoms, emotion regulation, goal navigation skills, and stress-sensitive biomarkers in young adult testicular cancer patients. Participants will be randomized to receive six sessions of GET or Individual Supportive Listening (ISL) delivered over eight weeks. In addition to indicators of intervention feasibility, the investigators will measure primary (depressive and anxiety symptoms) and secondary (emotion regulation and goal navigation skills, career confusion) psychological outcomes prior to (T0), immediately after (T1), twelve weeks after intervention (T2) and 24 weeks after the intervention (T3). Additionally, identified biomarkers will be measured at baseline and at T1, T2, and T3.
