PURPOSE: To investigate the effects of a group counseling education program (GCEP) provided to parents of children with autism spectrum disorder (ASD) on parents' psychological resilience, life satisfaction, and family functioning. METHOD: This experimental study was conducted with 30 parents of children with ASD. Data were collected using a Personal Information Form, the Adult Psychological Resilience Scale, Satisfaction With Life Scale, and Family Assessment Device. The GCEP, comprising 10 sessions, was provided to the intervention group once per week. RESULTS: The GCEP significantly increased psychological resilience levels in the intervention group compared to the control group. Although there were no significant differences between groups regarding Family Assessment Device subscale scores before the GCEP, after the program, mean scores on the subscales of problem solving, communication, roles, and behavioral control of the intervention group were significantly lower than those of the control group. No significant differences were observed in life satisfaction between groups. CONCLUSION: The GCEP was effective in improving psychological resilience and family functioning. Family counseling programs for raising awareness and provision of psychosocial support may be developed and applicable in relation to in-family relationships, care and responsibilities for the child, and problem solving for parents of children with ASD.
