Practitioners' Use and Evaluation of Transdiagnostic Youth Psychotherapy Years After Training and Consultation Have Ended.

We examined practitioners' use of the transdiagnostic Modular Approach to Therapy for Children (MATCH) 7 years after learning MATCH for a clinical trial. The practitioners (N = 29; Mage = 52.10, SD = 12.29, 86% women, 97% white) reported using MATCH with 55% of their caseload; use of the various MATCH modules ranged from 39 to 70%. Use was positively associated with amount of MATCH experience in the trial, perceived effectiveness, and ease of implementation. Patterns of specific module use did not consistently match strength of prior evidence (e.g., exposure was least used of the anxiety modules), suggesting challenges for implementation science.
