This school-based randomized controlled trial will: a) examine the effects of telehealth-administered Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST), an evidence-based depression prevention program, as compared to services as usual (SAU) on social processes and emotional and school outcomes, b) examine moderators and mediators of intervention effects, and c) assess the costs, cost-effectiveness, acceptability, feasibility, fidelity, and sustainability of IPT-AST.
This is a randomized clinical trial. Adolescents with elevated depressive symptoms will be identified and randomly assigned to IPT-AST delivered through telehealth by research staff (alone or in collaboration with school support staff) or services as usual (SAU) as delivered by counselors or other student support staff in schools. The research team will use longitudinal data collection with adolescents, parents, and counselors, and will collect data from teachers and school records to achieve study objectives. Participants will be 240 racially and ethnically diverse students in the 9th and 10th grades between the ages of 14 and 17 with elevated symptoms of depression and their parents. Counselors in local high schools will also be study participants. A subset of counselors, adolescents, and administrators will also participate in a qualitative interview as part of an implementation study. Adolescent participants will be randomly assigned to IPT-AST, an evidence-based depression prevention program, or SAU which may include supportive counseling and/or referral for services. Standardized measures for adolescents, parents, and teachers and school records will be used to examine emotional outcomes (e.g., depression and anxiety symptoms, depression diagnoses) and school outcomes (e.g., school engagement, grades). Investigators will utilize standardized measures to assess social processes (e.g., interpersonal conflict, social functioning) that may mediate the effects of the intervention on these emotional and school outcomes. Investigators will also collect data on services received in IPT-AST and SAU, techniques utilized in both conditions, and feasibility, acceptability, fidelity, sustainability, and costs of IPT-AST using session logs, time diaries, standardized measures, leader- and consultant-rated fidelity checklists, and qualitative interviews.

Depression symptoms
Change in depression symptoms will be measured by the Center for Epidemiologic Studies-Depression Scale (CES-D) which assesses the frequency of 20 depressive symptoms over the past week; CES-D scores range from 0 to 60 (scores of 16 or higher are considered elevated); higher scores indicate more depression symptoms
Time frame: Screen, baseline, 2 month, 3 month, 9 month, 15 month
Impairment
Change in impairment will be measured by the Columbia Impairment Scale (CIS), 13-item scale of overall functioning; scores range from 0-52; a score of 15 or higher is considered elevated impairment; higher scores represent greater impairment
Time frame: Baseline, 2 month, 3 month, 9 month, 15 month
Onset of depression diagnoses
The onset of diagnoses/change in depression diagnoses during the study period from eligibility to the 15 month assessment will be assessed by the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS-PL)
Time frame: Eligibility, 15 month
Change in academic grades
Impact of the intervention on school grades will be examined by accessing school records and looking at change in grades from baseline to the 15 month assessment.
Time frame: Baseline, 15 month
Change in school attendance
Impact of the intervention on school attendance will be examined by accessing school records and looking at change in attendance from baseline through 15 months.
Time frame: Baseline, 15 month
Internalizing and externalizing symptoms
Changes in internalizing and externalizing symptoms will be assessed by the Pediatric Symptom Checklist (PSC-17), which will be completed by teens, parents, and teachers; there is a total score (range of 0-34), internalizing subscale (0-24), externalizing subscale (0-20), and attention problems subscale (0-24); higher scores indicate more symptoms

Time frame: Baseline, 2 month, 3 month, 9 month, 15 month
Anxiety symptoms
Change in anxiety symptoms will be assessed by the Screen for Child Anxiety Related Disorders (SCARED), a 41-item scale assessing symptoms corresponding to different anxiety disorders; we will examine total scores and the following subscales: panic, GAD, and social anxiety; total scores range from 0-82 (25 or higher indicates clinical range); panic scores range from 0-26 (7 or higher indicates clinical range); generalized anxiety disorder scores range from 0-18 (scores of 9 or higher indicates clinical range); social anxiety scale ranges from 0-14 (scores 8 or higher indicate clinical range)
Time frame: Baseline, 2 month, 3 month, 9 month, 15 month
Number of disciplinary incidents
Impact of the intervention on school disciplinary incidents will be examined by accessing school records and looking at number of new disciplinary incidents from baseline to the 15 month assessment
Time frame: Baseline, 15 month
School connectedness
Changes in school connectedness will be measured by the Psychological Sense of School Membership Scale, an 18 item measure of school connectedness; scores range from 18-90; higher scores indicate higher school connectedness
Time frame: Baseline, 3 month, 9 month, 15 month
Emotional and behavioral engagement in learning
The short and long-term impact of the interventions on engagement in learning will be measured by change in the Engagement versus Disaffection with Learning measure, a 20-item scale that assesses emotional and behavioral engagement vs. disengagement in school; total scores range from 20 to 80; behavioral and emotional engagement scores range from 10 to 40, with higher scores indicating greater engagement
Time frame: Baseline, 3 month, 9 month, 15 month
Fidelity to the intervention
The IPT-AST Fidelity Checklist will be completed by counselors and consultant to rate fidelity to IPT-AST intervention; adherence in each session is rated as a percent adherent; quality of session is also rated as percent; higher scores indicate greater adherence and quality (implementation)
Time frame: Weekly during intervention delivery
Acceptability - counselors: A self-report measure, Counselor Feedback Form
A self-report measure, Counselor Feedback Form, will be completed by any counselors who co-lead IPT-AST to assess acceptability of IPT-AST following group (3 month) and booster sessions (15 month) (implementation)
Time frame: 3 month, 15 month
Acceptability - adolescents: A self-report measure, the Attitude Towards Intervention Questionnaire (ATI)
A self-report measure, the Attitude Towards Intervention Questionnaire (ATI), will be completed by adolescents to assess acceptability of IPT-AST following group (3 month) and booster sessions (15 month) (implementation)
Time frame: 3 month, 15 month

Qualitative interviews will be conducted with IPT-AST stakeholders to gather information on implementation of IPT-AST; this is a qualitative interview which will be coded for key themes
Time frame: 3 month
Attendance
Logs will track youth participation in IPT-AST and clinician attendance to IPT-AST consultation as one indicator of feasibility (implementation)
