AbstractBackground: Obesity is a widespread concern with both physical and psychological consequences in children and adults. Objectives: The aim of the present study is to explore the effectiveness of unified transdiagnostic treatment in addressing negative effects, shame, and self-criticism in obese children. Methods: In a randomized controlled and single-blind study, forty-four obese children were selected and divided into two groups. G*Power was used to determine the study sample size. The participants of this study were obese and overweight children aged 7 to 15 years. The treatment group received transdiagnostic treatment for 2 months, with sessions lasting about 90 minutes. Both groups completed various assessments before and after the intervention, including the positive and negative affect program for children and measures of external shame and self-criticism levels. Statistical analysis was performed using the method of covariance. Follow-up periods of 2 and 4 months were included. Results: The unified protocol (UP) had a significant effect on the study variables. In unified transdiagnostic therapy, negative affects, shame, and self-criticism significantly decreased (P < 0.05). Conclusions: Unified transdiagnostic treatment is effective in reducing negative affects, shame, and self-criticism. Since childhood obesity has unpleasant psychological consequences, psychological interventions to reduce its effects should be considered.en
