Reward Sensitivity Digital Intervention for Suicide Risk

The goal of this clinical trial is to develop and test an app designed to reduce suicide risk and improve emotional well-being in adolescents. The study will test if the app's daily check ins and recommended mood boosting skills will improve the adolescent's overall mood and suicidality. The main question it aims to answer is: • Is the app practical and acceptable to use daily? In the study, adolescents will: * Participate in a focus group with other adolescents and provide feedback on the app itself (design, ease of use, etc.). * Complete surveys and assessments on their mood, thoughts, and experiences. * Complete assessments about their app experience. In the study, the legal guardian of the adolescent will: * Participate in a focus group with other adolescents and provide feedback on the app itself (design, ease of use, etc.). * Complete assessments about their app experience.
