Reduced Stress, Enhanced Interaction: A Study on the Mechanisms of Integrated Online-Offline Interventions Improving Parent-Child Interaction Quality in Autistic Families

The goal is to improve problem behaviors and the quality of parent-child interaction. Twenty-six child-caregiver pairs participated in a randomized controlled design, assigned to either an immediate intervention group or a waiting-list control group.

Scales measured children's problem behaviours, parent-child interaction quality, and parental stress to evaluate outcomes and mediating mechanisms. Results showed significant reductions in both intensity and frequency of problem behaviours, as well as a marked decrease in parent-child conflict. Behavioural gains were stable during the maintenance period, with further increases in parent-child closeness seen at follow-up, indicating robust outcome stability.
