Pilot study of a strengths-based education program for Diné (Navajo) families of autistic children: Feasibility, fidelity, acceptability, and initial outcomes.

Purpose: Culturally responsive, strengths-based parent education and training programs for Indigenous families of autistic children are needed to help optimize their health; however, few exist. Parents Taking Action, an evidence-based, parent education and training program delivered by community health workers (i.e., family advisors), was adapted for Diné (Navajo) families of autistic children ages 2 to 12 years (Diné PTA). We conducted a pilot study to examine the feasibility, fidelity, acceptability, and initial outcomes of Diné PTA. Methods: Using mixed methods, program feasibility was assessed from participant enrollment and lessons completed; program fidelity was captured using a structured checklist; and initial family and child outcomes were measured with a verbally administered survey at baseline, mid-way through the program, and following program completion. The program's social validity and other aspects of its acceptability were assessed after program completion through the final survey, a virtual focus group with participants, and family advisor feedback. Paired t-tests with quantitative survey data and content analysis with qualitative data were performed. Results: Of the 13 Diné parents enrolled in the study, 10 completed all ( Conclusion: Results suggest Diné PTA holds promise as a culturally responsive, strengths-based autism education and training program for Indigenous families.
