Descriptive and analytic statistics were computed according to demographic information, emotional eating scale and Dutch eating behavior questionnaire. Intervention included 13 sessions of 1.5hr group therapy, DBT-skills training from April to September 2019. Mixed-effect modeling ANOVA with repeated measurements was performed by statistical analyses, IBM SPSS version 24 to study changes in variables over time.
Results: The results demonstrated that the emotional such as anger, anxiety and depression, significantly decrease during the study period. (P-value<0.001) As well as behavioral eating demonstrated significant improvement in restrained eating and decrease in emotional and external eating behaviors right after the end of intervention while trial group experienced significant weight loss.
