The moderating effects of dispositional affectivity on relationships between job characteristics and nurses' job satisfaction.

Using the job satisfaction model embedded in the Price-Mueller nurse turnover model, the moderating effects of positive affectivity (PA) and negative affectivity (NA) on the relationships between the seven independent variables in the model and job satisfaction were examined. Multiple regression procedure was used to analyze data collected from 162 nursing employees of a 327-bed Veterans Administration Medical Center. The major determinants of job satisfaction were found to be routinization, instrumental communication, and PA. The impact of participation, instrumental communication, integration, distributive justice on job satisfaction were found to be moderated by PA. NA moderated the impact of promotional opportunity on job satisfaction. These predictors, in conjunction with demographic variables, explained 45% of the variance of job satisfaction.
