Development and psychometric validation of the Sickness Presenteeism Scale-Nurse

This study's aim is to develop and psychometrically assess the Sickness Presenteeism Scale-Nurse. Evaluation of the effects of sickness presenteeism on nurses' performance and productivity is important for healthcare quality. This was an instrument development and validation study. Scale items were created based on literature review and qualitative research. Data were collected from 619 nurses between October and December 2021. The factor structure of the scale was determined by explanatory and confirmatory factor analysis performed with different sample groups. Convergent and discriminant validity were investigated, and reliability was evaluated with Cronbach's α values, adjusted item-total correlation, composite-reliability and split-half reliability. Explanatory factor analysis showed that Sickness Presenteeism Scale-Nurse consisted of four sub-dimensions and 21 items and explained 57.9% of the total variance. This factor structure was confirmed by confirmatory factor analysis. The convergent and discriminant validity was confirmed. The total Cronbach's α value of the scale was calculated as 0.928, with Cronbach's α values of the sub-dimensions calculated as 0.815-0.903; composite reliability values were calculated as 0.804-0.903. The Sickness Presenteeism Scale-Nurse is a valid and reliable measurement instrument that can be used to evaluate the effect of nurses' sickness presenteeism behaviour on job performance.
