    Abstract

    This study introduces a therapist-report measure of evidence-based practices for adolescent conduct and substance use problems. The Inventory of Therapy Techniques-Adolescent Behavior Problems (ITT-ABP) is a post-session measure of 27 techniques representing four approaches: cognitive-behavioral therapy (CBT), family therapy (FT), motivational interviewing (MI), and drug counseling (DC). A total of 822 protocols were collected from 32 therapists treating 71 adolescents in six usual care sites. Factor analyses identified three clinically coherent scales with strong internal consistency across the full sample: FT (8 items; α = .79), MI/CBT (8 items; α = .87), and DC (9 items, α = .90). The scales discriminated between therapists working in a family-oriented site versus other sites and showed moderate convergent validity with therapist reports of allegiance and skill in each approach. The ITT-ABP holds promise as a cost-efficient quality assurance tool for supporting high-fidelity delivery of evidence-based practices in usual care.
