This was a quasi-experimental pilot study conducted over six months in five provincial hospitals. Forty-six caregiver-child pairs participated in the intervention, which included biweekly in-clinic I-CARE skills coaching (Interaction, Comfort, Adapt, Respond, Encouragement), parent support groups, and home-based activities. Outcomes were assessed using the Functional Emotional Assessment Scale (FEAS), I-CARE Assessment, and Parenting Stress Index-Short Form (PSI-SF). Parent-child interaction improved significantly (I-CARE scores increased from 12.69 ± 5.08 to 16.60 ± 6.45, <em>p</em> &lt; .001), as did children’s social-emotional development (FEAS scores increased from 28.67 ± 9.34 to 35.31 ± 9.21, <em>p</em> &lt; .001). Parental stress decreased significantly (PSI-SF scores from 94.89 ± 13.40 to 85.09 ± 12.43, <em>p</em> &lt; .001). Provinces with fewer resources showed the greatest improvements, particularly among children under three years old. The THAI model represents a paradigm shift in early ASD intervention by decentralizing care to families and communities, empowering caregivers, and addressing disparities in access. This scalable, culturally adapted approach holds promise for reducing health inequalities in LMICs.</p> Tamara Sumalrot Prapa Maisook Koonthaleeporn Srijun Thanayot Sumalrot Kaewta Nopmaneejumruslers Copyright (c) 2026 International Journal of Child Development and Mental Health https://creativecommons.org/licenses/by-nc-nd/4.0 2026-01-21 2026-01-21 14 1 1 21
