The second part of the study will develop and refine digital versions of the remaining sessions of STAR and a digital general health promotion intervention. It will do this by using focus group feedback from approximately 20 adolescents in mental health treatment, and approximately 10 community advisory board members which include variety of staff from mental health treatment settings such as administrators, supervisors, therapists, health teachers at therapeutic schools, clinicians at day hospitals and day treatment programs, parents of youth in mental health treatment and from relevant community organizations, such as those serving lesbian, gay, bisexual, transgender, and questioning youth. Feedback on D*STAR prototype sessions will also be collected from two individual interviews with approximately 20 youth in mental health treatment. All developed sessions (from both Phase I and Phase II) will then be reviewed in an open trial with approximately 20 adolescents. A randomized control trial (RCT) will then be conducted to compare D*STAR to a time matched digital general health promotion intervention among approximately 120 adolescents. For the pilot and RCT phases, assessments will be administered prior to randomization, immediately following the last intervention session, and at one month post-intervention (pilot study) or at three month post-intervention (RCT).
