Measuring life stress: A comparison of the predictive validity of different scoring systems for the social readjustment rating scale

Abstract

Previous literature in the area of life stress has suggested a number of variables that may moderate the amount of stress associated with life events. The present study attempted to determine whether accounting for these variables in the scoring of the Social Readjustment Rating Scale (SRRS), a measure of life stress, would improve the predictive validity of the inventory. Through a random canvassing of residential areas, 107 sets of questionnaires were completed, including a modified SRRS, the Symptom Checklist-90, the Life Satisfaction Index, several health measures, and a demographic data sheet. On the basis of correlational analysis it was concluded that income and level of education are significant predictors of the capacity to cope with stress. By the criteria established for selecting the most appropriate life stress scoring system, it was decided that stress is best measured by asking respondents to check those events in the past year that had been undesirable to them. Theoretical and practical implications of these findings are discussed.
