Background and Aims: Traumatic events can have profound psychological impacts, ranging from distress to positive transformations known as posttraumatic growth. This study aimed to examine the mediating role of inhibitory control in the relationship between deliberate rumination and posttraumatic growth among patients with cancer in Isfahan, Iran.
Materials and Methods: This descriptive-correlational study was conducted on all patients with cancer who referred to oncology departments of medical centers in Isfahan, Iran, during 2023–2024. A total of 200 patients were selected using convenience sampling. Data were collected using the Posttraumatic Growth Inventory developed by Tedeschi et al., the Barkley Deficits in Executive Functioning Scale, and the Event-Related Rumination Inventory developed by Cann et al. Data analysis was performed using linear regression with a bootstrap approach.
Results: The results indicated that the direct effect of deliberate rumination on posttraumatic growth was 0.46 (P<0.001), while the indirect effect of deliberate rumination on posttraumatic growth through inhibitory control was 0.27 (P < 0.001). These findings confirm the significant mediating role of inhibitory control (P< 0.001). Furthermore, the mediation ratio of 0.37 revealed that approximately 37% of the total effect of deliberate rumination on posttraumatic growth was transmitted through inhibitory control (P< 0.001).
Conclusion: Given that deliberate rumination influences posttraumatic growth through inhibitory control, interventions aimed at strengthening inhibitory control may be beneficial in enhancing posttraumatic growth among patients with cancer
