Abstract
Latino individuals with autism spectrum disorder (ASD) face unique challenges during their transition to adulthood. This study evaluates ¡Iniciando! la Adultez, a culturally adapted behavioral health program aimed at addressing the co-occurring mental health needs of Latino young adults with ASD and their families. The program integrates culturally relevant elements to enhance engagement and effectiveness. Results indicated that the behavioral health intervention was associated with significant reductions in anxiety and depressive symptoms, highlighting the urgent need for tailored behavioral health services in this population. Additionally, the involvement of parents in group therapy demonstrated a positive impact on both parental and young adult mental health, underscoring the importance of supporting both young adults and their caregivers during this critical transition. These findings emphasize that culturally adapted behavioral health interventions can effectively address the distinct needs of Latino young adults with ASD, ultimately contributing to improved mental health outcomes and quality of life. Given the systemic disparities faced by Latino families, this study underscores the necessity for ongoing development and evaluation of culturally informed behavioral health services to support the well-being of this underserved population, particularly as they navigate the complexities of adulthood.
