National norms and life-event frequencies for the revised Social Readjustment Rating Scale

The revised 51-event Social Readjustment Rating Scale (SRRS) was administered to a representative national sample of 5,000 in order to construct and interpret norms for overall scale scores and life-event frequencies. Directions asked for the frequency of each life-event during the previous 12 months. Life-event frequencies for each subject were multiplied by previously determined stressfulness ratings to produce an overall scale score. Norms for overall scale scores and life-event frequencies were calculated. A total of 3,399 completed surveys were returned (68%). The distribution of overall scale scores had a mean of 278, standard deviation of 422, and marked positive skewness of 4.12. Five of the top 10 most frequently occurring life-events were directly related to work. The normative information concerning overall scores on the revised Social Readjustment Rating Scale can be invaluable in understanding and interpreting individual scores, as well as diagnosing or identifying at-risk individuals with high scores who would likely benefit from stress management interventions.
