title: A comparison of life events scoring methods as predictors of psychological symptomatology.
abstract: Seven scoring methods for the Life Events Survey (LES) were compared to determine which, if any, is superior for prediction of psychological symptomatology as measured by the Brief Symptom Inventory (BSI). Every scoring method tested, except one utilizing an individual's positive ratings of events, was significantly correlated with symptomatology. The method using an individual's negative ratings of events was a significantly better predictor than any other. These findings suggest several conclusions. First, nomothetic methods for weighting life events do not increase a scale's predictive ability beyond that achieved by a frequency count of events. Second, frequency of life events predicts psychological symptomatology only insofar as life events are perceived as negative. That is, positively perceived events do not predict symptomatology. Finally, a life events scale's predictive ability is increased by utilizing the individual's negative perceptions of events.
