Objectives To test the predictive value and convergent construct validity of a 6‐item work functioning screener (WFS‐H). Methods Healthcare workers (249 nurses) completed a questionnaire containing the work functioning screener (WFS‐H) and a work functioning instrument (NWFQ) measuring the following: cognitive aspects of task execution and general incidents, avoidance behavior, conflicts and irritation with colleagues, impaired contact with patients and their family, and level of energy and motivation. Productivity and mental health were also measured. Negative and positive predictive values, AUC values, and sensitivity and specificity were calculated to examine the predictive value of the screener. Correlation analysis was used to examine the construct validity. Results The screener had good predictive value, since the results showed that a negative screener score is a strong indicator of work functioning not hindered by mental health problems (negative predictive values : 94% ‐98%; positive predictive values: 21%‐36%; AUC: .64‐.82; sensitivity: 42%‐76%; and specificity 85%‐87%). The screener has good construct validity due to moderate, but significant ( p <.001), associations with productivity ( r =.51), mental health ( r =.48), and distress ( r =.47). Conclusions The screener (WFS‐H) had good predictive value and good construct validity. Its score offers occupational health professionals a helpful preliminary insight into the work functioning of healthcare workers.
