In 1967, psychiatrists Thomas Holmes and Richard Rahe examined the medical records of over 5,000 medical patients as a way to determine whether stressful events might cause illnesses. Patients were asked to tally a list of 43 life events based on a relative score. A positive correlation of 0.118 was found between their life events and their illnesses.

Their results were published as the “Social Readjustment Rating Scale” (SRRS), known more commonly as the Holmes and Rahe Stress Scale. Subsequent validation has supported the links between stress and illness.
