Supporting Research
Rahe carried out a study in 1970 testing the reliability of the stress scale as a predictor of illness. The scale was given to 2,500 US sailors and they were asked to rate scores of 'life events' over the previous six months. Over the next six months, detailed records were kept of the sailors' health. There was a +0.118 correlation between stress scale scores and illness, which was sufficient to support the hypothesis of a link between life events and illness.
In conjunction with the Cornell medical index assessing, the stress scale correlated with visits to medical dispensaries, and the H&R stress scale's scores also correlated independently with individuals dropping out of stressful underwater demolitions training due to medical problems. The scale was also assessed against different populations within the United States (with African, Hispanic and White American groups). The scale was also tested cross-culturally, comparing Japanese and Malaysian groups with American populations.
