Psychometric Properties of the Work Well Index: A Short Questionnaire for Work ‐Related Stress

Abstract The aim of this study was to test the psychometric properties of a short questionnaire for work‐related stress entitled Work Well index (WWi) and its interaction with different variables of self‐reported health. An online survey was conducted in a sample of 1,218 employees (51% female) in four countries of an international insurance company. Internal consistency reliability, factorial validity, convergent validity and criterion validity of the 10‐item WWi were analyzed. Good internal consistency reliability of the WWi was obtained (Cronbach's α coefficient = 0.85). Confirmatory factor analysis showed a satisfactory model fit of the data (AGFI = 0.92). The WWi was highly correlated to conceptually close constructs such as demand–control, effort–reward imbalance and workplace social capital (p < 0.001). Moreover, the 10‐item WWi was significantly (p < 0.001) associated with elevated risk of self‐rated health, absenteeism, presenteeism and depression (odds ratio 1.63, 1.36, 2.08, 2.95, respectively). We conclude that this short questionnaire is a reliable and valid instrument measuring psychosocial stress at work. Copyright © 2016 John Wiley & Sons, Ltd.
