A NEW QUANTITATIVE APPROACH TO MEASURE PERCEIVED WORK-RELATED STRESS IN ITALIAN EMPLOYEES By Cevenini, G., Fratini, I., & Gambassi, R. (2012) Cevenini, Fratini, and Gambassi (2012) goal was to give accurate quantification of what participants perceived occupational stress to be. Their study is a new quantitative approach of questionnaire data collection and analysis. They chose a statistical multivariate procedure. Their aim was to obtain a one-dimensional estimation of occupational stress which would guide psychologist through intervention strategies to protect workers’ health and safety (Cevenini, Fratini, & Gambassi, 2012).
Methods
Cevenini, Fratini, and Gambassi (2012) shortened their questionnaire by using the principal component analysis. PCA was performed by rotating the solutions with Varimax method and Kaiser Normalization (Velicer, 1990). Cevenini, Fratini, and Gambassi (2012) provided a score for each of the six stress dimensions. This was useful to characterize the different types of stress perceived by the employees. The risk scores were gathered by multivariate statists’ procedures that sequentially combined a clustering technique with linear discriminant analysis (Krzanowski, 1988). Assumption of the linear discriminant function as risk score, was expressed as a percentage of the whole score range. Cronbach’s analysis was performed by Cevenini, Fratini, and Gambassi (2012) to test their statistical consistency and reliability (Gonbach & Shavelson, 2004). A one-dimensional quantitative description of each aspect was obtained using the same clustering approach as for risk scores by maximizing the discrimination level between low and high values of D, R and S, detected by empirical data through non-hierarchical cluster analysis. The solution of the associated linearized system gave: ß0 = 120, ^ = 0.08654 and ß2 = 0.00561. Under the hypothesis of
