A Pre-Implementation Enhancement Strategy to Increase the Yield of Training and Consultation for School-Based Behavioral Preventive Practices: a Triple-Blind Randomized Controlled Trial

Abstract

As the most common setting where youth access behavioral healthcare, the education sector frequently employs training and follow-up consultation as cornerstone implementation strategies to promote the implementation of evidence-based practices (EBPs). However, these strategies alone are not sufficient to promote desirable implementation (e.g., intervention fidelity) and youth behavioral outcomes (e.g., mitigated externalizing behaviors). Theory-informed pragmatic pre-implementation enhancement strategies (PIES) are needed to prevent the lackluster outcomes of training and consultation. Specifically, social cognitive theory explicates principles that inform the design of PIES content and specify mechanisms of behavior change (e.g., "intentions to implement" (ITI)) to target increasing providers' responsiveness to training and consultation. This triple-blind parallel randomized controlled trial preliminarily examined the efficacy of a pragmatic PIES based on social cognitive theories (SC-PIES) to improve implementation and youth behavioral outcomes from universal preventive EBPs in the education sector. Teachers from a diverse urban district were recruited and randomly assigned to the treatment (SC-PIES; n_treatment = 22) or active control condition (administrative meeting; n_control = 21). Based on the condition assigned, teachers received the SC-PIES or met with administrators before their EBP training. We assessed teachers' ITI, intervention fidelity, and youth behavioral outcome (academic engagement as an incompatible behavior to externalizing disorders) at baseline, immediately after training, and 6 weeks afterward. A series of ANCOVAs detected sizeable effects of SC-PIES, where teachers who received SC-PIES demonstrated significantly larger improvement in their ITI, intervention fidelity, and youth behaviors as compared to the control. Conditional analyses indicated that teachers' ITI partially mediated the effect of SC-PIES on intervention fidelity, which in turn led to improved youth behaviors. Findings suggest that theory-informed pragmatic PIES targeting providers' ITI can boost their responsiveness to implementation strategies, as reflected in improved implementation behaviors and youth behavioral outcomes. The results have implications for targeting motivational mechanisms of behavior change and situating preventive implementation strategies at the intersection between the preparation and active implementation stages of an implementation process. Limitations and implications for research and practice are discussed. Clinicaltrials.gov: NCT05240222. Registered on: 2/14/2022.
