Effectiveness of an Online Psychological Support Program for Mothers of Children Diagnosed With Autism Spectrum Disorder: A Controlled Study

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by difficulties in social communication and interaction, repetitive behaviors, and restricted interests. Since ASD is a developmental disorder that affects language, speech, cognitive, social, and emotional skills, raising a child with ASD can be a challenging experience for parents. Parents of children with ASD generally experience higher levels of stress, anxiety, and depression compared to parents of typically developing children, and their chronic stress levels are also higher compared to parents of children with developmental delays. A longitudinal study has shown that acceptance plays a protective role in parents' adaptation to an autism diagnosis and is associated with lower levels of depression both cross-sectionally and over time. In contrast, caregivers with increasing levels of self-blame and hopelessness toward the diagnosis have been observed to experience worsened mental health and decreased life satisfaction.

Acceptance and Commitment Therapy (ACT) is a form of cognitive-behavioral therapy that focuses on acceptance and mindfulness. This therapeutic approach aims to increase psychological flexibility by altering individuals' relationship with events and their function through six flexible hexagonal concepts (acceptance, defusion, present moment contact, context-based self, values, and value-driven behavior). A review study conducted in 2022 demonstrated that ACT interventions for parents of children with ASD can be beneficial.

The rationale for this study stems from the need for approaches to improve the mental health of mothers of children diagnosed with ASD, as these mothers experience higher levels of stress, anxiety, and depression. The literature on the effects of ACT-based interventions on parents' psychological well-being is limited. Research on the effectiveness of ACT-based psychological support programs for parents of children with ASD is still in its early stages. Therefore, it is important to evaluate how ACT-based psychological support programs affect the anxiety, stress, and depression levels of parents of children with ASD, the factors related to these effects, and how reductions in parenting stress influence children's behavioral problems and autism severity.
