RESUMO
IMPORTANCE: Some autistic adults experience depression and anxiety related to their social relationships. There is a need for evidence-based occupational therapy interventions that decrease depression and anxiety and improve the health of social relationships for autistic adults. OBJECTIVE: To determine the feasibility and preliminary effectiveness of the Healthy Relationships on the Autism Spectrum (HEARTS) intervention, a six-session, group-based psychoeducational intervention for the improvement of relationship health. DESIGN: One-group pretest-posttest design with a 3-mo follow-up after baseline. SETTING: United States; online intervention through community organization. PARTICIPANTS: Fifty-five adults, ages 20 to 43 yr, with a professional or self-diagnosis of autism and the capacity to independently participate in an online, group-based, participatory class. INTERVENTION: Participants received 6 90-min weekly sessions that addressed healthy relationship topics, including recognizing abuse, meeting people, maintaining relationships, setting interpersonal boundaries, neurohealth for relationships, and ending relationships. A psychoeducational approach that provided education and involved guided discovery and strategy acquisition was used. OUTCOMES AND MEASURES: All measures were self-administered through an online survey. Depression and anxiety were assessed using instruments from the Patient-Reported Outcomes Measurement Information System. RESULTS: Fifty-five participants completed the intervention. Postintervention scores revealed statistically significant improvements in depression and anxiety. CONCLUSIONS AND RELEVANCE: HEARTS is a promising intervention for improving depression and anxiety among autistic adults and should be investigated further. What This Article Adds: HEARTS offers a potentially effective, nonpharmacological, psychoeducational group-based intervention option to promote healthy relationships for autistic adults.
