Standardization and Evaluation of Psychometric Properties of the self-perceived burden Questionnaire (SPBQ) in chronic pain patients

Background and Objectives: Self-perception burden is one of the most important aspects of chronic pain. the present study is to determine the psychometric properties of the Self-perception burden Scale a sample of Iranian chronic pain patients. Methods: In this study, 324 male and female chronic pain patients in Tehran were examined by the available sampling method. For convergent validity, the DASS-21 questionnaire and chronic pain catastrophe questionnaire were used, and for divergent validity, chronic pain self-efficacy questionnaire and life satisfaction questionnaire were used. Also, to determine the reliability, the internal consistency method was used by Cronbachchr('39')s alpha method to determine the validity of the structure and the reliability of the test-retest at four-week intervals, confirmatory factor analysis was used using LISREL software version 8.8. Results: Cronbachchr('39')s alpha coefficient for the total score of the scale was 87% and test-retest reliability were85%. DASS-21 and chronic pain catastrophe scales showed a positive and significant relationship with the SPB questionnaire and also chronic pain self-efficacy and life satisfaction scales had a significant and negative relationship with the SPB questionnaire. In addition, the results of confirmatory factor analysis showed that the single-factor structure has a good fit. Conclusion: The Iranian version of the Self-perception burden Scale reflects desirable validity and reliability and can be used to diagnose and screen chronic pain patients.
