The Social Readjustment Rating Scale (SRRS), developed by Dr. Thomas Holmes and Dr. Richard Rahe in 1967, is designed to measure the likelihood of stress-induced illness.

Studies indicate that stress weakens the immune system and decreases resistance to illnesses such as heart disease and ulcers.

To measure your stress, identify the events in the below list that you encountered over the last 12 months, then tally the Life Change Units.
