We assessed parent stress and competence outcomes from participation in a randomized controlled trial of a modular behavioral intervention (Modular Approach for Young Autistic Children
MAYAC) compared to a treatment-as-usual comprehensive behavioral intervention (CBI). Throughout their participation, parents of military families were included in their child's treatment (e.g., identifying goals, learning strategies to support their child) and reported on their feelings of stress using the Parenting Stress Index-4, Short Form (PSI-4), as well as their feelings of satisfaction and efficacy as a parent on the Parenting Sense of Competence (PSOC) scale. A linear mixed model evaluated the differences in stress and competence from baseline to each assessment period through follow-up. There were no significant differences between groups in stress or competence ratings
however, there were within-group changes in both treatment arms over the course of the trial. In both groups, parent stress decreased, and competence increased over time, continuing to suggest that behavioral analytic intervention for young children with autism can promote positive parent outcomes.
