Abstract: (1605 Views)
Objective: The present study aimed to examine the effectiveness of acceptance and commitment therapy (ACT) on cognitive flexibility and rumination in individuals with sexual obsession.
Methods: This research employed a quasi-experimental design with pretest–posttest and a control group. The statistical population consisted of all male clients diagnosed with sexual obsession in Isfahan in 2024. A purposive sample of 30 individuals was selected and randomly assigned to an experimental group (n = 15) and a control group (n = 15). The experimental group received eight 90-minute sessions of ACT intervention. Data were collected using the Cognitive Flexibility Inventory (Dennis & Vander Wal, 2009) and the Rumination Questionnaire (Nolen-Hoeksema & Morrow, 1991). Multivariate analysis of covariance (MANCOVA) was used for data analysis.
Results: After controlling for pretest scores, significant differences were observed between the experimental and control groups in posttest scores (p < 0.001). ACT significantly increased cognitive flexibility and reduced rumination in the intervention group. The observed effect sizes for both variables ranged from moderate to high.
Conclusions: These findings suggest that ACT, by fostering skills such as acceptance, mindfulness, and commitment to values, can serve as an effective intervention for reducing rumination and enhancing cognitive flexibility in patients with sexual obsession.
