Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to address implementation challenges faced by some evidence-based youth psychotherapies. FIRST was developed as transdiagnostic approach—guided by five empirically supported principles of therapeutic change. Measures utilized include the Therapist Integrity in Evidence-Based Interventions (TIEBI), the Therapeutic Alliance Scale for Youths (TASC-C) and Parents (TASC-P), the Client Satisfaction Questionnaire (CSQ-8), the Therapist Satisfaction Inventory (TSI), the Brief Problem Checklist (BPC), the Top Problems Assessment (TPA), the Clinical Global Impression–Improvement (CGI) Scale, the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS), the Child Behavior Checklist (CBCL), the Youth Self Report (YSR), and the Services for Youths and Adolescents-Parent Interview (SCAPI). Results indicate weekly assessments throughout FIRST treatment showed effect sizes for clinical improvement ranging from 0.41 to 2.66 on weekly total problems and problems deemed “most important” by caregivers and youths. Limitations include small sample size, an open trial design, and diversity was limited.

Length of postintervention follow-up: None.
