Development of a College Student-Delivered Cognitive-Behavioral Therapy (CBT) Intervention for Rural High School Students

Overview

This research is being done to find out the effectiveness, feasibility, and acceptability of a college student-delivered cognitive-behavioral therapy (CBT) intervention in high schools in rural Schuylkill County, Pennsylvania to treat mental health problems (i.e. depression and anxiety) in adolescents. This project will respond to the need for evidence-based, acceptable, accessible, and low-cost adolescent cognitive-behavioral interventions that lead to long-term improvements in adolescents' mental health outcomes.

The overarching goal of this study is to iteratively adapt and test an innovative mental health delivery model that leverages college students to provide cognitive-behavioral therapy (CBT) to high school students in rural Schuylkill County, Pennsylvania. The investigators' preliminary data and established Community Advisory Board (CAB) support three key premises that drive this project. First, depression, anxiety, and stress are the most prevalent mental health challenges facing rural adolescents. Second, multiple barriers impede access to mental health care in rural communities, including provider shortages, mental health stigma, cost, insurance constraints, and limited parental knowledge or support. Third, these barriers can be addressed by enhancing school-based mental health services through a novel delivery model: licensed psychologists training undergraduate students to provide CBT interventions directly in high school settings. Aim 1: Iteratively adapt and pilot CBT for high school students in rural Pennsylvania. The investigators will employ a systematic adaptation process guided by their preliminary data and the Framework for Reporting Adaptations and Modifications-Enhanced (FRAME) to develop a culturally responsive and contextually appropriate CBT intervention for rural high school settings. This iterative refinement process will integrate feedback from two complementary sources: (1) semi-structured interviews with high school student participants and college student interventionists; and (2) a CAB comprising high school students, parents/caregivers, school mental health providers, school administrators, and college student interventionists. By the end of the two-year project period, the investigators will have developed a CBT intervention specifically tailored for high school students in rural Pennsylvania, with clear documentation of adaptation decisions and their empirical basis. Aim 2: Examine the effects of the adapted CBT intervention on mental health outcomes among rural high school students. The investigators will evaluate preliminary effectiveness using self-report measures of depression, anxiety, and stress in 24-40 high school students (6-10 students/CBT group) across four implementation periods. Outcomes will be measured at pre-treatment, mid-treatment, and post-treatment. The investigators hypothesize that the adapted CBT intervention will result in at least a 50% decrease in mental health symptoms. Aim 3: Evaluate the feasibility, acceptability, engagement, and fidelity of the adapted CBT intervention. The investigators will employ a mixed-methods approach to comprehensively evaluate four key implementation outcomes. Feasibility will be assessed through recruitment and retention metrics, while acceptability will be measured via standardized instruments and stakeholder feedback. Engagement will be tracked through session attendance and participation rates, and fidelity will be monitored through systematic assessment of intervention delivery. The investigators hypothesize that the adapted CBT intervention will meet or exceed pre-determined benchmarks across all implementation outcomes.
