The present study aimed to investigate the effectiveness of moderated mood-based Schema Therapy for Children and Adolescents (ST-CA) in the internalizing behaviors problems in adolescents referred to consulting center in Ahvaz.Methods: The study was quasi-experimental with a pre-test and post-test design and a control group. The statistical population comprised adolescents aged ۱۲-۱۴ years having behavioral, educational, and mood problems who were referred to counseling centers in Ahvaz (Iran). The sample consisted of ۳۰ adolescents (۱۱ boys and ۱۹ girls) selected by convenience sampling and randomly divided into experimental and control groups (n= ۱۵ per group). The experimental group underwent fourteen sessions (۱۲۰-minutes sessions per week) of moderated mood-based ST-CA. The research instrument included the Child Behavior Checklist (CBCL). Data analysis was done using SPSS version ۲۶.Results: The present study's findings revealed that moderated mood-based ST-CA had a significant effect on the improvement of the internalizing problems (anxiety-depression, withdrawal-depression, and somatic complaints) (P< ۰.۰۰۱). Conclusion: It seems that the moderated mood-based ST-CA well reduces internalizing problems; therefore, the use of this method for adolescents is recommended.
