The Naples-Questionnaire of Work Distress (nQ-WD): Bullying at workplace, organizational dysfunctions and bio-psycho-social effects.

The aim of this study is to elaborate a tool, the “Na- ples-Questionnaire of Work Distress” (nQ-WD), in order to evaluate the conditions of discomfort per- ceived in the working field. It tries to differentiate the dysfunctional phenomena more tied to the anomalies of the interpersonal relationships (bullying at work- place) from the phenomena more clearly related to organizational dysfunctions. The inventory measures the overall effects of these two areas on the subject and the spin-off in term of bio-psycho-social func- tioning. The questionnaire has been administered to a group of 178 workers who showed a work-related psychopathological disturbance and to a control gro- up of 178 subjects without exposure to bullying at workplace or to organizational distress. The statisti- cal analysis demonstrated degree of significant valid- ity and reliability. The degree of internal coherence of the answers proposed is satisfactory. The ROC curves allow the determination of a threshold value which allows separating the workers subjected to mobbing and/or organizational stress from control-workers with an optimal reliability degree. The values of the area under the ROC curves show that the inventory has a high discriminating capacity.
