Background and Aims: Breast cancer is the most common cancer among women and has profound effects on physical and psychological health. Development of supportive interventions for the survivors of this disease is essential to improve the quality of life and psychological adjustment. The present study aimed to investigate the effectiveness of metacognitive therapy on post traumatic growth, positive illness perception, and body acceptance in women with breast cancer after mastectomy.
Materials and Methods: This quasi-experimental study used a pretest-posttest design with a control group and a one-month follow-up. The study population consisted of women aged 35–55 years with breast cancer who had undergone unilateral mastectomy at Omid Hospital, Urmia, Iran, during 2024-25. In total, 40 participants were selected through purposive sampling and then randomly assigned to experimental and control groups using a simple lottery method. The instruments included the Post-Traumatic Growth Inventory (PTGI; Tedeschi & Calhoun, 1996), the Positive Illness Perception Scale/Silver Lining Questionnaire (SLQ-38; Sodergren & Hyland, 2000), and the Body Acceptance Scale for Breast Cancer Survivors (BAS-BC; Ahn & Suh, 2018). The experimental group received eight 90-minute sessions of metacognitive therapy. Data were analyzed using repeated-measures analysis of variance through SPSS software (version 26).
Results: The results showed significant differences between pretest and posttest, as well as between pretest and follow-up, in terms of post-traumatic growth, positive illness perception, and body acceptance, indicating considerable improvement in these variables (P < 0.05). The mean score of post-traumatic growth increased from 27.10 at pretest to 53.80 at posttest, positive illness perception increased from 65.80 to 85.35, and body acceptance increased from 28.80 to 48.90. Moreover, the differences between posttest and follow-up were not significant, suggesting that the effects of metacognitive therapy remained relatively stable over time (P > 0.05).
Conclusion: The findings suggest that metacognitive therapy may contribute to improving post-traumatic growth, positive illness perception, and body acceptance in women with breast cancer after mastectomy. Therefore, metacognitive therapy may be considered a potentially useful component of supportive psychological interventions for women with breast cancer after mastectomy.
