Background <p>Early motor delays are common and can have lasting consequences. Gaps between delay identification and caregiver support often cause stress. We hypothesized that a social-media-delivered intervention supporting caregivers of children with motor delays could improve understanding of development/parenting, and self-efficacy; we explored effects on caregiver stress, implementation fit/feasibility.</p> Methods <p>This single-blind Phase 1b randomized controlled trial with wait-list control and implementation exploration included caregivers of children 3–36 months corrected age (CA) with motor delays. Interactions occurred via Facebook private groups and REDCap. Knowledge questionnaires, parental-self efficacy scale, Parenting Stress Index and Developmental Assessment of Young Children physical domain (DAYC-2 Phys) were administered pre/post-intervention.</p> Results <p>Within the cohort, caregivers (<i>n</i> = 31 intervention, <i>n</i> = 31 waitlist) reported that 13% of children had only motor delays, 63% also had diagnosed cerebral palsy, and 24% also had other types of complex medical conditions (e.g.,&#xa0;chronic lung disease, feeding disorder). The intervention group had greater knowledge gains and fewer instances of parental distress scores in the clinical range (<i>p</i> &lt; 0.01) with no effects on self-efficacy. Feasibility and acceptability were high for delivery format and content; positive perceptions, sense of connection and empowerment predominated. Negative feedback concerned technical issues and study design.</p> Conclusion <p>This social-media-delivered intervention showed social connection was valued and may reduce parent distress. Implementation and future research are well supported.</p> Trial registration number and name <p>NCT05542251, Education Program for Caregivers of Children with Gross Motor Delays.</p> Impact <p><UnorderedList Mark="Bullet"> <ItemContent> <p>Social connection is valued by families of young children with motor delays and impairments.</p> </ItemContent> <ItemContent> <p>Interventions leveraging social media can decrease stress and increase knowledge for these families.</p> </ItemContent> <ItemContent> <p>Social media delivered interventions are feasible and acceptable to families as they wait for specialized early intervention services.</p> </ItemContent> <ItemContent> <p>Further studies are needed to research whether social-medial delivered interventions can also improve the motor outcomes of children with motor delays.</p> </ItemContent> </UnorderedList></p>
