Implementation strategy mapping methods to improve autism intervention use in community settings: a study protocol

Implementation strategies are purported to facilitate adoption and use of evidence-based practices (EBPs) across settings. The use of tailored implementation strategies may be particularly effective, as they are selected with the explicit purpose of addressing setting-specific implementation determinants. However, methods to select and tailor implementation strategies, including in community settings, remain understudied. This project will identify and describe implementation strategy mapping methods (ISMMs) from extant peer-reviewed literature and pilot test a method to match implementation strategies with determinants in low-resourced community mental health (CMH) agencies that deliver services to children on the autism spectrum.

Aim 1: A scoping review, following PRISMA guidelines, will be conducted to identify implementation strategy mapping methods (ISMMs) utilized in child mental health settings. Data extraction will identify and describe each ISMM, including identifying methodological and procedural steps, analyzing the frequency of ISMM use, and identifying outcomes measured in eligible ISMM studies. Aim 2: Using scoping review findings, select and pilot test one ISMM within five community mental health agencies in Michigan that provide services to autistic children. We will recruit five directors/agency leaders, supervisors, and direct providers at each of the eligible agencies (expected N = 25). A sequential explanatory (QUAN➔ QUAL) mixed methods design will be used. Participants will complete a demographics and client survey, as well as a needs assessment to identify implementation determinants. The impact of the ISMM on organizational readiness for change (from pre- to post-ISMM), as well as implementation outcomes of the ISMM (feasibility, acceptability, appropriateness, usability), will be examined. Semi-structured interviews will elicit stakeholder perspectives on the mapping method.

The current project aims to advance our knowledge of methods for selecting, tailoring, and mapping implementation strategies to address context-specific determinants to implementation. Additionally, this project will contribute to growing science found at the intersection of implementation science and autism research by utilizing the implementation determinants framework, the CFIR, to guide data collection, analysis, and interpretation of findings. Finally, these findings may support future EBP implementation efforts within low-resourced communities, with the ultimate goal of increasing equity in access to EBPs for autistic children.
