Question:
Burnout of human services professionals. Emotional exhaustion, or burnout, is a significant problem in the field of human services. Regression analysis is often used to investigate the relationship between burnout and aspects of the human services professional’s job and job-related behavior (One of the first applications was published in the Journal of Applied Behavioral Science, Vol. 22, 1986.) Emotional exhaustion can be measured with the Maslach Burnout Inventory, a questionnaire. Consider an independent variable called concentration, measured as the proportion of social contacts with individuals who belong to a person’s work group. The table on the next page lists the values of the emotional exhaustion index (higher values indicate greater exhaustion) and concentration for a sample of 25 human services professionals who work in a large public hospital. A Minitab printout of the simple linear regression is provided below the table.
a. Construct a scatterplot for the data. Do the variables x and y appear to be related?
b. Find the correlation coefficient for the data and interpret its value. Does your conclusion mean that concentration causes emotional exhaustion? Explain.
c. Test the usefulness of the straight-line relationship with concentration for predicting burnout. Use a = .05.
d. Find the coefficient of determination for the model and interpret it.
e. Find a 95% confidence interval for the slope b1. Interpret the result.
f. Use a 95% confidence interval to estimate the mean exhaustion level for all professionals who have 80% of their social contacts within their work groups. Interpret the interval.
