Assessing the Link Between Stress and Health

Thomas Holmes and Richard Rahe concluded on the basis of their research that change-whether it be positive change or negative change-is stressful and that people who experience dramatic changes in their lives are at risk for illness and injury. They developed a method evaluating how much change and, consequently, how much stress is in a person's life called the Social Readjustment Rating Scale (SRRS). This SRRS is reproduced for you for the purposes of this experiment on the Record Form on page 300.

The purpose of this experiment is to investigate the relationship between stress, as measured by the SRRS, and illness and injury. To perform the exercise, you will need to find 10 cooperative and truthful volunteers who are willing to fill out a questionnaire that will take about 5 minutes. Try to find some volunteers who have experienced a high degree of stress in their lives and some who seem to have had very little stress. You will also need to make 10 copies of the Record Form printed below, one for each of the 10 subjects in this exercise.

Procedure

STEP 1 Give each subject a copy of the Record Form and ask him or her to fill it out as accurately as possible. Be sure to tell the subjects that they need not put their names on the forms and their identities will not be revealed to anyone who might look at the data.

STEP 2 Collect the Record Forms and thank the subjects for their help. Assign a subject number from 1 to 10 on the top of each form.

Analyzing the Data

STEP 1 Score each subject's SRRS by adding together all the numbers that correspond to the circled events on each subject's Record Form. Record these numbers in the appropriate positions on the chart in Table 15.1, along with the subject number on the top of the Record Form.

STEP 2 Record the answers given by each subject to Questions 1 through 6 in the spaces provided in Table 15.1.

STEP 3 Examine the trends in the data carefully to determine the relationship between high stress as measured by the SRRS and the amount of illness and injury experienced by individuals in these three categories.

Do your data show any indication of a relationship between stress and illness or injury? More specifically, do subjects whose SRRS scores fall above 300 report more visits to the doctor, more serious illnesses, more injuries, more trips to the doctor, etc., than those whose SRRS scores fall below 100?

One of the questions which is left largely unanswered in this approach to studying the relationship between stress and health is the question of causality: What causes what? Does stress cause a person to be at risk for illness and injury? Or does having more illnesses and injuries over a relatively brief span of time produce more stress? How would a biomedical model address this issue? What would a biopsychosocial model conclude? Can you think of ways to test these different explanations about the relationship between stress and health? Based on your reading of Chapter 15, do you think that stress produces an increased risk of illness and injury? What evidence would you use to support your answer?
