Validity of Einarsen and Raknes s Negative Acts Questionnaire in a sample of workers belonging to the horticulture sector

Mobbing or workplace bullying generates severe consequences for workers health and the organization itself It is therefore important to provide assessment instruments tailored to detect mobbing in specific sectors. The central purpose of this study is the validation of the Negative Acts Questionnaire (NAQ; Einarsen & Raknes, 1997) in a Spanish sample of 638 workers belonging to the horticulture sector. Results of confirmatory factor analysis indicated two factors, consistent with those proposed by Einarsen and Hoel (2001), referring to the two broad categories of harassment: predatory bullying and work related bullying. Finally, the NAQ reflects suitable reliability and validity. Hence, it may be used as an estimate of mobbing in Spanish organizations operating in the horticulture sector.
