The present study aimed to examining the effectiveness of group positive parenting training on increasing hope and life satisfaction in mothers of children with autism. Method: This was a quasi-experimental study with pretest, posttest, and control and experimental groups. Mothers with autistic children (6-15 years) in Rasht consisted the statistical population of the study. All the children had a medical record and autism diagnosis based on DSM-IV-TR by a psychiatrist. Hope Questionnaires by Snyder and Life Satisfaction Questionnaire by Diener were implemented. Participants of the experimental group received positive parenting training for 8 sessions, and participants of the control group were put in the state of waiting. Descriptive statistics (mean, standard deviation, frequency, and percentage) and inferential statistics (univariate and multivariate covariance analysis) were used for data analysis. Results: In this study, 27 mothers of children with autism were examined. The mean and standard deviation of the age of mothers in the experimental group was 36.14± 2.47 years and it was 37± 3.62 years for mothers in the control group. The results of univariate covariance analysis revealed a significant difference between the scores of pretest and posttest of the experimental and control groups in life satisfaction (Sum of square = 16.558, F = 13.534, DF = 1, P = 0.002, 〖=ƞ〗^2 = 0.361). Conclusion: The results of this study showed that using group positive parenting training can have a positive effect on dimensions of hope and life satisfaction in mothers of children with autism spectrum disorder. https://ijps.tums.ac.ir/index.php/ijps/article/view/965 https://ijps.tums.ac.ir/index.php/ijps/article/download/965/728
