Patients and methods: This methodological and cross-sectional study was conducted with 80 female patients (mean age: 49.5±10 years; range, 28 to 75 years) diagnosed with fibromyalgia syndrome between January 2020 and December 2021. Participants completed the Turkish version of the CPAQ-8, as well as the Fibromyalgia Impact Questionnaire, Brief Pain Inventory, Hospital Anxiety and Depression Scale, and Tampa Kinesiophobia Scale. Internal consistency, confirmatory factor analysis, and construct validity were examined in the statistical analysis of the data obtained.

Results: The two-factor model created by exploratory factor analysis provided a better fit than the global factor model. Cronbach's alphas of both subscales of the CPAQ-8 were found to be 0.76 and 0.80; therefore, they provided internal consistency. The CPAQ-8 was found to be significantly correlated with all other scales compared.

Conclusion: The Turkish version of the CPAQ-8 is an assessment tool with sufficient validity in assessing pain acceptance levels in fibromyalgia patients experiencing chronic pain. Future studies are needed to evaluate the validity and reliability of the questionnaire in different chronic pain models. Keywords : Chronic pain, fibromyalgia syndrome, pain acceptance
