Psychometric Properties of the Thai Version of Copenhagen Burnout Inventory (T-CBI) in Thai Nurses

Abstract

Background: Burnout has consistently been an influential predictor of intention to leave nursing profession. Assessing nurses’ burnout is highly crucial in retaining qualified nurses and alleviating nursing shortage. The Copenhagen Burnout Inventory was originally developed in English and has been modified and translated into Thai. Psychometric properties of the Thai version of Copenhagen Burnout Inventory has not been investigated. Methods: The purpose of study was to examine psychometric properties of the Thai version of Copenhagen Burnout Inventory (T-CBI). The T-CBI is a self-reported questionnaire that consists of 19 items with five response categories. It contains three dimensions: personal burnout, work-related burnout, client-related burnout. The 207 registered nurses working in governmental hospitals of Bangkok Metropolitan in Thailand were recruited using random sampling approach. Statistical analyses included confirmatory factor analysis and measures of descriptive statistics, item analysis, criterion validity, internal consistency, and test-retest reliability. Results: The T-CBI demonstrated good reliability and validity. Cronbach’s alpha coefficient was 0.96. Corrected item-total correlations for the total scale were positive (range from 0.33 to 0.82). Construct validity was supported by confirmatory factor analysis. Results indicated that criterion related validity was well correlated with a previously validated measurement. Conclusion: The test results indicated the T-CBI scale appear to be a reliable and valid instrument. It has potential benefit for assessing burnout among Thai nurses. The current findings should be of benefit for nurse administrators and policy makers, to assess burnout among nurses that could develop strategies in retention and prevent qualified nurses from leaving the profession.
