| Summary: | Background: Catastrophizing is an important psychological construct in mediating the behavioral response toward pain.
Objective: The purpose of this study is to examine the psychometric properties of the Pain Catastrophizing Scale (PCS) in Greek clinical population.
Methods: The scale was administered in 376 patients with chronic cervical and lumbar pain. Test–retest reliability, internal consistency (Cronbach α) and concurrent validity were assessed. Exploratory (EFA) and Confirmatory Factor Analysis (CFA) were used to test the factorial validity of the hypothesized three factor structure.
Results: The PCS factors suggested high levels of test–retest reliability, whereas Cronbachs’ α values were acceptable. The EFA yielded a three-factor solution and indicated a marginal fit to the data. CFA procedures indicated a rather acceptable fit to the data. The concurrent validity of the instrument was confirmed.
Conclusion: PCS seems to be a reliable and valid instrument in Greek patients with chronic cervical and lumbar pain. |
