Quasi-experimental Controlled Study on the Effect of Autism Resource Clinic Guardian Attendance at a Military Treatment Facility.

INTRODUCTION: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition that requires multidisciplinary care. Evidence-based practice indicates that early intervention may improve long-term ASD outcomes. The Autism Resource Clinic (ARC) provides an educational session for guardians empowering them to build a personalized ASD team for their child. We examined the impact of guardian attendance of an ARC at a Military Treatment Facility on time to initiation of patient services and guardian stress level.

MATERIALS AND METHODS: A quasi-experimental controlled study was conducted comparing a group of guardians attending the ARC with a group of guardians not attending the ARC following a child's initial ASD diagnosis. ARC speakers included medical, county/state, community/military, and advocacy experts. Surveys were completed at diagnosis, 1, 2, and 3 mo postdiagnosis. Initiation of patient services and Parental Stress Scale scores were compared between groups using independent samples t-test, chi-square tests, or nonparametric tests, as appropriate.

RESULTS: Use of Applied Behavioral Analysis was significantly higher among ARC attendees vs. nonattendees (73.3% vs. 33.3%, P = 0.028). County early intervention was more frequent among ARC attendees versus nonattendees (40% vs. 13.3%, P = 0.09). Of borderline significance, median time to initiation of genetics services was greater in ARC attendees vs. nonattendees (106 vs. 65.5, P = 0.10). The two groups did not differ on changes in Parental Stress Scale score from baseline to follow-up months 1, 2, or 3.

CONCLUSIONS: Although ARC did not influence time to initiation of patient services or guardian stress level, attendance of ARC was associated with more frequent use of Applied Behavioral Analysis services and county early intervention services. This pilot study is unique as it targets guardians of ASD patients within military treatment facilities. Study limitations include data collection during the coronavirus disease 2019 pandemic, sequential evaluation of experimental and control groups, sample size and generalizability. A large, multicenter, randomized controlled trial is required to better assess the impact of this educational opportunity among military populations.
