Effectiveness of the Stepping Stones Triple P Group Parenting Program as an Additional Intervention in the Treatment of Autism Spectrum Disorders: Effects on Parenting Variables

Parents of children with autism spectrum disorders (ASD) often are faced with the challenges of difficult parenting situations. We explored the effectiveness of the Stepping Stones Triple P (SSTP) group parent training as an additional intervention in the treatment of ASD. Parents (n = 23) went through a waiting period and participated afterwards in the training program. We assessed parenting variables via self-report measures. After the intervention, there was a significant reduction of over-reactive parenting behaviors, role restriction and an increase in parental self-efficacy. At follow-up, the effects remained stable and we additionally found a reduction of laxness and less parenting stress. Effect sizes were high (η2: 0.18–0.24). The SSTP, offered as an additional intervention in the treatment of ASD, proved to be effective in enhancing parenting.
