Enhancing Parent–Child Interaction and Self-Efficacy in Motor Skills Development for Young Children with Developmental Delays

Background/Objectives: The present study investigated the effects of parental participation in home program intervention on parent–child interactions, parental self-efficacy, and the goal attainment of children with developmental delays in motor skills. Methods: While the interviews consisted of qualitative data, quantitative analyses were applied to the results, making this a mixed-methods study. Participants were 2–6-year-old young children and their families. Twenty-three parent–child dyads were randomly assigned to an intervention group (n = 13) or a comparison group (n = 10). Outcomes were evaluated using the Parent–Child Interaction Questionnaire and Parental Self-Efficacy Questionnaire. Results: Improvements in parental self-efficacy and in the Goal Attainment Scale scores of the children were evident in the posttest, whereas no evidence of differences in improvement was found in parent–child interactions between the intervention and comparison groups on the pretest and posttest. Conclusions: Parent collaboration with therapists has a significant impact on achieving functional goals for young children, and parental involvement in intervention programs effectively enhances parental self-efficacy.
