EXERCISE 17.2: PREDICTING THE WORK MOTIVATION OF VOLUNTEERS OBJECTIVE: To examine the validity and cross-validity of a set of predictors.

PROLOGUE: Because volunteers are unpaid, the work motivation of these individuals can be complex. It is possible that individuals’ work motivation depends on their perceptions of their own ability, along with elements of support provided by the organization.

The SPSS data file “Volunteer Data.sav” (see Appendix B) contains data assessed from 120 volunteers in a number of small organizations. Each volunteer completed a survey, as shown in Table 17.1, assessing the following perceptions Each of the scales was assessed using either a five-point or a seven-point Likerttype rating scale. An additional variable included in the data set, work motivation, will act as the criterion variable in Exercises 17.2 and 17.3.
