Our findings support the validity and reliability of the BP-PCS. The scale showed satisfactory psychometric properties. CFA provides support for the three-factor structure reported in previous studies. This factor structure presented good discriminative properties to identify catastrophizers who present with mild chronic pain, fibromyalgia, and CTH. The BP-PCS is a valuable tool for use in scientific studies and in the clinical setting in patients with chronic pain in Brazilian Portuguese-speaking countries.
