The impact of negative affectivity on stressor strain relations: A replication and extension

The present study was a replication and extension of the results of Brief et al. (1988), who found that partialling out negative affectivity reduced the magnitude of stressor-strain correlations considerably. The effect of both trait anxiety and dispositional optimism was partialled out from stressor-strain correlations. Unlike Brief et al. (1988), however, work stress was measured with specific stressor scales rather than life events. Results from two samples of university employees showed that partialling out trait anxiety, dispositional optimism, or both, reduced the magnitude of stressor-strain correlations very little. Thus, it does not appear that stressor-strain correlations can be attributed to negative affectivity. The possibility that the results of the study by Brief et al. (1988) may have been due to problems with the life events approach used to measure work stress is discussed. Future research on the impact of dispositions is suggested.
