Development of the Social Readjustment Rating Scale [by Holmes and Rahe 1967]

AIM: -

The 2 medical doctors developed the SRRS in order to test their hypothesis that, “stress as created by life events was a cause of physical illness”.

PROCEDURES: -

*They observed that patients tended to have experienced several life events in the months before the onset of illness.

*To test their hypothesis they developed the SRRS, by examining 5000 patient records and making a list of 43 life events that seemed to precede illness.

*Then they asked about 400 participants to rate each item in terms of stress it produced.

*They assigned a random value of 500 to marriage as a reference point. Specifically they asked participants to think of each event and to answer the question “is this event indicative of more or less readjustment than marriage?”.

*At the end, they averaged everyone’s results and divided by 10 to get a measure of the individual events in terms of life change units [LCU’s]. LCU represented the degree of stress caused by an event.

*Holmes and Rahe used their questionnaire with various sub-groups to see if the ratings were consistent. There was strong agreement been different groups, which suggested that it was a valid measure for all types of people.

*Using the SRRS involves asking participants to indicate which out of 43 life events have happened to them over a period of time.

*A life event score is then calculated by adding up the LCU’s for each event ticked.

FINDINGS: -

*According to Holmes and Rahe any change whether desirable or undesirable can be stressful.

*The evidence from numerous studies using the SRRS is that people who have experienced events totalling more than 300 life change units over a period of 1 year are more at risk for a wide range of physical and mental illnesses. These illnesses include: heart attacks, diabetes, TB, anxiety and depression [Martin 1989]

*However, the correlations between life change units and susceptibility to any particular illness and to be rather low, indicating a weak association between life events and illness.

*Number of events reported decreases with age and increases with education.

*Single, separated, and divorced people reported more events than married and

* Widowed persons.

CONCLUSION: -

Participants responding to the SRRS check the items they experienced in the past, for example within the last year. The life-change values of the checked items are then summed up to yield a total score that indicates how much “stress” the individuals had. For ...
