An Investigation of Potential Sources of Bias in Self-Report Job Analysis Data.

Abstract

The present research was an exploratory laboratory and field investigation of possible sources of bias in self-report job analysis data. Because of the similarity between task perceptions and job analysis data, the research into task perceptions was used as a starting point for the present study. In the laboratory study, 129 undergraduate psychology students were asked in Session 1 to complete measures of field independence, mental ability, intrinsic work orientation, and self-esteem. In Session 2, subjects were assigned to either a clerical or manufacturing task in which student confederates expressed either positive or negative cues about the task. Subjects then completed a job analysis instrument and a measure of job satisfaction. Results indicated some main effects for these variables on job analysis data, although effects were often task specific. In a partial replication in a field setting, 56 bank tellers were asked to complete measures of job satisfaction, intrinsic work orientation, demographic variables, and a job analysis instrument. Results indicated some main effects for some demographic variables on job analysis data. The results of these two studies were discussed in terms of their implications for future job analysis research as well as for job analysis in organizational settings.
