Psychometric properties and cut‐off scores for the Swedish version of the Negative Acts Questionnaire: The full scale and short version

The present study investigates the psychometric properties and cut‐off scores of a Swedish version of the Negative Acts Questionnaire, the most frequently used instrument to measure exposure to workplace bullying. Based on a probability sample of the Swedish workforce ( n = 1853), we investigate the validity of both the full version (NAQ–R) and the short version (SNAQ). We suggest optimal cut‐offs for the NAQ–R and SNAQ, and for the subscales measuring work‐ and person‐related bullying. Based on the cut‐off scores we provide estimates of prevalence in a Swedish context. The factor structure and psychometric properties are comparable to the Norwegian original and the English versions of the instrument. We also tested the criterion validity using 11 outcome and antecedent variables to bullying, and all provided support for its validity. The identified cut‐off scores differentiate clearly when tested against the 11 variables used to test criterion validity in the study. The results showed that the Swedish version of the NAQ–R, including the SNAQ, is a valid measure of workplace bullying. To our knowledge, this study is the first study presenting statistical cut‐offs for the NAQ‐R subscales as well as investigating both the NAQ‐R and the SNAQ simultaneously. The present study also provides some criticism against and suggestions for improving the NAQ–R, aiming to capture even more of the overall experience of exposure, ability to defend oneself, overall duration, and on‐ and offline exposure.
