Development and psychometric evaluation of COVID-19 psychological burden scale for Indian health care workers
Abstract
Background: It is beyond doubt that the health care systems across the globe have been experiencing burdens of unprecedented magnitude in the coronavirus disease (COVID-19) era. However, no psychometric tools were validated in India to assess the impact of COVID-19 on the psychological well-being exclusively among health care workers, given their obvious risk for exposure. Objectives: This study was conducted to develop the first of its kind psychometric tool that measures the psychological burden posed by COVID-19 on Indian health care workers. Materials and Methods: One hundred and sixty-nine health care workers attending COVID-19 duties in four different states of India took part in the study. The initial scale designed was tested for face and content validity. Exploratory factor analysis using direct oblimin rotation with Kaiser normalization was employed to determine the factor structure. Differential item functioning (DIF) analysis with ordinal regression based on the type of COVID-19 facility at which the participant is serving, educational background was done for identification of item bias. Results: COVID-19 Psychological Burden Scale for Indian Health Care Workers (CPBS-IHCW), with 17 items loaded on four components, demonstrated good internal consistency reliability (Cronbach's Alpha 0.873). DIF revealed no item bias based on type of facility and educational background. Significant differences in CPBS-IHCW scores were noted between health care workers serving at different COVID-19 facilities and belonging to different educational backgrounds. Conclusion: CPBS-IHCW is a 17-item, rapidly administrable scale, demonstrating good internal consistency reliability, and temporal stability, which can be used in the assessment of psychological burden among health care professionals catering to the needs of the COVID-19 affected.
