Abstract

This study aimed to evaluate the effects of cognitive-behavioral therapy (CBT) on negative problem orientation, anxiety sensitivity, and self-compassion among patients with fibromyalgia. The research employed a quasi-experimental design with a pretest-posttest control group. The statistical population consisted of fibromyalgia patients attending pain clinics in Rasht city during 2024. Using purposive sampling, 36 participants were selected and randomly assigned to either the experimental group (n = 18) or the control group (n = 18). The instruments utilized included the Negative Problem Orientation Questionnaire (NPOQ; Rubichad & Douglas, 2008), the Anxiety Sensitivity Index-3 (ASI-3; Taylor et al., 2007), and the Self-Compassion Scale (SCS; Neff, 2003). The experimental group underwent 10 sessions of 90-minute CBT. Data were analyzed using multivariate analysis of covariance. Results indicated that CBT significantly reduced negative problem orientation (F = 71.57), physical factor (F = 64.17), cognitive factor (F = 59.44), social factor (F = 82.43), and significantly increased self-compassion (F = 39.10) in fibromyalgia patients. The results of the present study indicated that CBT significantly reduced negative problem orientation and anxiety sensitivity, while increasing self-compassion in patients with fibromyalgia. These findings highlight the effectiveness of this approach in improving psychological components associated with chronic pain.
