Abstract
Background:Autism spectrum disorder has a big impact on family life. Mothers of children with autism face many challenges. This study was conducted to determine the effectiveness of group-based acceptance and commitment therapy on cognitive emotion regulation strategies in mothers of children with autism. Method:This is a quasi-experimental study with a pretest-posttest control group design. The research population included mothers of children with autism spectrum disorder referring to exceptional schools, who were living in Tehran. After cluster random sampling, 30 mothers of children with autism spectrum disorder were selected and randomly assigned to two groups: an experimental group and a control group, each consisting of 15 women. Participants responded to the cognitive emotion regulation questionnaire vulbefore and after intervention. The experimental group received group-based acceptance and commitment therapy (eight two-hour sessions), while no intervention was given to the control group. Results and conclusion:Covariance analysis of data showed that group-based acceptance and commitment therapy had a significant effect on positive/planning strategy refocusing (p=0.003), positive reappraisal (p=0.004), self-blaming (p=0.001), blaming others (p=0.007), considering a situation as disastrous (p=0.001), reception (p=0.008). However, there was not a significant difference in the dimensions of rumination (p=0.025). Therefore, it is recommended that welfare institutions and centers should provide a training plan based on acceptance and commitment therapy to improve the current cognitive emotion regulation strategies for mothers of children with autism spectrum.
