Abstract
The Pain Beliefs and Perceptions Inventory (PBPI) is one of the most applicable measures for assessing beliefs among pain patients. To date, this instrument has not been tested for its applicability and validity in Belarusian populations. To translate the English language version of the PBPI into Russian (R-PBPI) and to evaluate its reliability, validity, and factor structure. A total of 238 Belarusian patients with heterogeneous chronic pain were recruited from a neurologic outpatient clinic of a public hospital in Minsk. In addition to the pain beliefs, some the other factors such as pain catastrophizing, depression, disability, pain intensity and demographic characteristics were examined. Exploratory factor analyses, using the principal components analysis, revealed a four-factor structure for R-PBPI. Results also showed that R-PBPI has adequate internal consistency (Cronbach’s αs: 0.73–0.85). The four R-PBPI scales showed significant positive correlations with DASS-d, PCS, pain intensity, and disability. Results of hierarchical multiple regression analyses showed the R-PBPI scales predicted concurrent depression (F (4, 221) = 3.75, p < 0.000), pain intensity (F (4, 218) = 6.01, p < 0.000), and pain disability (F (4, 215) = 4.41, p < 0.000) scores. These findings support the factorial validity of the scales of the R-PBPI as well as its reliability and construct validity. Our study support the use of the R-PBPI for clinical or research purposes identifying or evaluating pain beliefs.
