Evaluating the Feasibility of a School-based Stepped Care Program for Internalizing Symptoms in Adolescents in Pakistan

Background: Internalizing symptoms among adolescents can have long-term devastating impacts on their lives unless they are identified and treated early and effectively. Both universal and indicated school-based interventions are recommended to address internalizing symptoms among adolescents. However, determining the optimal timing and dosage of these interventions remains a crucial question for effective adolescent mental healthcare. The investigators will conduct a pilot Sequential Multiple Assignment Randomized Controlled Trial (SMART) to explore the feasibility and acceptability of two evidence-informed intervention strategies (universal and indicated interventions) within the stepped care model, compare their timing and dosage, and determine in which sequence these interventions should be delivered to whom. This study aims to answer the question, "What works, for whom, under what conditions, and why, for internalizing symptoms in adolescents with a focus on depressive symptoms?" Methods: A 20-week single-blind pilot cluster SMART study will be conducted in 8 public schools in Rawalpindi, Pakistan, to assess the feasibility and acceptability of 2 intervention strategies (i.e., 1. teachers plus non-specialist delivered universal intervention called Enhanced School Mental Health Program \[eSMHP\] Plus and 2. Guided self-help application of Cognitive Behavioural Therapy-based indicated intervention to reduce depression (internalising symptoms) in adolescents. The study participants will be approximately 200 adolescents, aged 13-15 of both sexes, with psychosocial distress. Data on the feasibility and acceptability of the study design, views about augmented intervention options and procedures, and treatment response rates will be collected. Results from the pilot study will yield additional research questions and will improve our ability to successfully conduct the definitive SMART to inform personalised interventions for internalising symptoms in adolescents. Discussion: The findings of the study will be used to inform the design of a subsequent fully powered, definitive SMART study in Pakistan.
