Arm && Interventions

Group	Intervention	Description
Single Arm	Sonoma Rises	21 male and female teenage participants will be randomized to one of three varying baseline assessment periods of two, four, or six weeks. Multiple baseline is a type of single-case experimental design (SCED) that is a time- and cost-effective method for evaluating efficacy of a new treatment, Sonoma Rises. The randomization of participants to baseline periods of varying lengths enables assessment of whether symptom changes occur when, and only when, the intervention is applied.
