Abstract: (50 Views)

Present study aimed to investigate the effectiveness of metacognitive therapy in reducing dysfunctional thoughts among individuals diagnosed with Major Depressive Disorder (MDD). The research design was quasi-experimental, employing a pretest–posttest design with a control group. The statistical population included all patients diagnosed with MDD in the city of Bandar Abbas who had visited psychiatric clinics between April until September 2022. From this population, 30 participants were selected through convenience sampling and were randomly assigned to experimental and control groups. The research instruments included the Beck Depression Inventory (BDI) and Dysfunctional Attitudes Questionnaire by D’Alessandro and Burton (2006), which were administered to both groups before and after metacognitive intervention. The experimental group participated in metacognitive therapy sessions, whereas the control group did not receive any intervention during the study period. Data were analyzed using one-way analysis of covariance (ANCOVA) with SPSS version 26. The results indicated that metacognitive therapy had a statistically significant effect on reducing dysfunctional thoughts in individuals with Major Depressive Disorder (p < 0.01). Therefore, it can be concluded that therapists and psychologists may utilize metacognitive therapy as an effective approach to reduce dysfunctional thoughts in patients with MDD.
