Abstract: (15 Views)
Background and Objective: Body dysmorphic disorder (BDD) severely impairs psychological well-being. The present study aimed to compare the effectiveness of Stress Inoculation Training (SIT) and mindfulness training on appearance anxiety and self-criticism in female adolescents with BDD.
Materials and Methods: A quasi-experimental pretest-posttest design with a two-month follow-up and a control group was utilized. Using purposive sampling, 45 female adolescents (aged 15–17) with BDD were selected from psychological centers in Ahvaz, Iran, in 2025, and randomly assigned to SIT (n=15), mindfulness skills training (n=15), or control (n=15) groups. The SIT group received nine 90-minute sessions, and the mindfulness group received eight 90-minute sessions. Data were collected using the Appearance Anxiety Inventory and the Levels of Self-Criticism Scale and analyzed via repeated-measures analysis of variance (ANOVA).
Results: Both SIT and mindfulness training significantly decreased appearance anxiety and self-criticism compared to the control group (P<0.001), with gains maintained at follow-up. No significant difference was observed between the two active interventions.
Conclusion: The SIT and mindfulness skills training are equally effective interventions for reducing appearance anxiety and self-criticism in female adolescents with BDD. These findings highlight the value of both cognitive-behavioral and acceptance-based approaches and provide clinicians with flexible, evidence-based options tailored to individual needs.
