Holmes and Rahe Stress Scale

Holmes and Rahe Stress Scale is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Holmes and Rahe Stress Scale rather than just read about it. In short: The Holmes and Rahe Stress Scale (), also known as the Social Readjustment Rating Scale, is a list of 43 stressful life events that can contribute to illness. The test works via a point accumulation score which then gives an assessment of risk.

Reference excerpt

The Holmes and Rahe Stress Scale (), also known as the Social Readjustment Rating Scale, is a list of 43 stressful life events that can contribute to illness. The test works via a point accumulation score which then gives an assessment of risk. The American Institute of Stress, for instance, regards a score of 300 or more as an "80% chance of health breakdown within the next 2 years". While there is good evidence that chronic stress can lead to ill health, there is not much evidence to support the ranking of stressful life events in this manner.

Development 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 and dependence 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.

Subsequent research Rahe carried out a study in 1970 testing the validity 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, Mexican and White American groups). The scale was also tested cross-culturally, comparing Japanese and Malaysian groups with American populations. A 1975 article in Journal of Human Stress (Behavioral Medicine) by psychologist David Mechanic noted the Holmes stress inventory had proved useful but also identified several limitations, including:

Lack of differentiation between favorable versus adverse life events Ambiguity of life events described Confounding dependent and independent variables Lack of specificity in items listed

Adults The sum of the life change units of the applicable events in the past year of an individual's life gives a rough estimate of how stress affects health.

Score of 300+: At risk of illness. Score of 150-299: Risk of illness is moderate (reduced by 30% from the above risk). Score < 150: Slight risk of illness.

Non-adults A modified scale has also been developed for non-adults. Similar to the adult scale, stress points for life events in the past year are added and compared to the rough estimate of how stress affects health.

Score of 300+: At risk of illness. Score of 150-299: Risk of illness is moderate. (reduced by 30% from the above risk) Score < 150: Slight risk of illness.

Worked examples

Example 1 — a first encounter with Holmes and Rahe Stress Scale

Start with the simplest possible case. Write down what Holmes and Rahe Stress Scale claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Holmes and Rahe Stress Scale before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Holmes and Rahe Stress Scale ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Holmes and Rahe Stress Scale

In research: Holmes and Rahe Stress Scale appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Holmes and Rahe Stress Scale in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Holmes and Rahe Stress Scale is common in secondary-school and first-year university syllabi. It links to neighbouring topics Medical scales, Psychological stress, Psychological tests and scales, so understanding it makes those chapters shorter.
In everyday life: Look for Holmes and Rahe Stress Scale outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
