Abstract
Workplace violence is a significant problem in industry, especially among rank-and-file workers, known as “blue-collar workers”. This systematic review and meta-analysis aim to evaluate the suitability of the reduced Negative Acts Questionnaire (NAQ-R) as an instrument to measure workplace violence in this type of population and synthesize the results of studies that have used it in different industrial sectors. A systematic review was conducted in accordance with the PRISMA 2020 statement. Publications describing populations of industrial workers were identified and included in the meta-analysis. For meta-analysis, we extracted data that allowed us to estimate the effect size of the included studies. We used a random-effects model to estimate the overall effect size and assessed heterogeneity between studies using the I2 statistic. The global effect size test showed that the overall effect size was significantly different from zero (3.00, t=22.28, p<0.001), indicating an overall effect in relation to workplace violence measured by the NAQ-R in industrial workers. Our results support the claim that the NAQ-R is an effective tool for assessing workplace violence among industrial workers. These findings have important implications for practitioners and researchers working in the field of industrial psychology and occupational health.
