Infancy, a formative period for development, has been identified as an advantageous time to provide family-centered support for children with delays. Families should be included as stakeholders during development of such interventions to ensure social value. We describe a preliminary randomized controlled trial evaluating Infant Achievements (IA), an 8-week (16-session) parent-mediated intervention for parents of infants 8-12 months old with social and communication delays. This study reports our qualitative examination of the intervention's social validity. We conducted focus groups with seven IA parent participants and analyzed their responses using conventional content analysis. Five themes emerged: (a) difficulty identifying resources to address concerns; (b) seeking validation of concerns; (c) seeking support to enhance children's development; (d) experiencing a supportive coaching relationship; and (e) creating meaningful interactions to support children's communication and social skills. Our results emphasize the necessity of partnering with families in the development of evidence-based, family-centered interventions for infants with developmental delays to maximize their social value.
