1 San Jose State University School of Social Work ScWk 242 Spring 2008 Lab Exercise #4B: Multiple Linear Regression ANSWER KEY Research Scenario 1b: Regression You are a program manager in a large public child welfare agency located in an urban county. The programs you manage employ a total of 40 social workers who provide a variety of case management services to children and families involved in the child welfare system. As a program manager you are particularly interested in reducing employee turnover by preventing employee stress and burnout. You suspect that number of clients on caseload is related to employee stress levels. You ask your employees (N=40), to complete an employee stress survey that measures employee stress levels on a continuous scale with 0 = No stress, and 30 = High stress. The survey also asks employees to indicate the types of stress-reducing activities they regularly engage in, including such things as exercise. In addition the survey also contains demographic questions including race/ethnicity, age and gender. Given the significant relationship that was found between caseload and employee stress level, you would like to learn more about the strategies that employees use to effectively cope with stress, including the role of exercise in reducing stress level. In order to help isolate the effect of exercise on employee stress level, you would like to statistically control for the potential confounding factors of number of clients on caseload, race/ethnicity, age, and gender.
