Director - Industrial & Organizational Psychology
Neil Christiansen received his B.S.E. from University of Wisconsin-Whitewater. After a brief experience teaching in the public schools, he completed an M.A. in Social Psychology from Southern Illinois University, followed by a Ph.D. in Industrial/Organizational (I/O) Psychology from Northern Illinois University. Prior to coming to CMU in 1997, he chaired the I/O program at Florida Tech and worked as a consultant in test development and personnel selection.

Effects of Personality on Work Strain: The role of job-person fit
The role of personality in determining job-person fit (P-J) was examined in the context of how the misfit can result in stress-based responses and strains. Drawing on Trait Activation Theory, the model posits that personality affects the work activities employees seek out on the job and how comfortable they are performing required activities. When workers have trait elevations that result in better fit (based on the congruence with the tasks performed), they will experience more positive work outcomes. To examine this, managers (N=334) completed a personality inventory, rated the frequency of task performance and their discomfort when performing those activities, and evaluated their perceptions of person-job fit, emotional exhaustion, and anxiety. Results indicated that managers who were low on Five-Factor Model traits avoided tasks where higher elevations were related to success and that they experienced more discomfort when performing them. The results also confirmed that these factors were related to evaluations of whether managers perceived that the fit the job and more emotional exhaustion and anxiety.
Departures from Linearity as Evidence of Applicant Distortion on Personality Tests
Three studies examined how faking impacts the normally linear construct relationships of personality tests by partitioning samples and measuring the effects on validity across different ranges of test scores. Study 1 constructed samples (n = 300) in a simulation using data from a laboratory faking study and systematically varied the proportion of distorted responses. Increase of faking in the samples predicted departures from linearity, with decreased convergent validity and increased saturation with social desirability at the top of the samples. Study 2 investigated validity decay across score ranges of applicants to a state police academy (n = 442). Personality test scores from the top of the distribution poorly predicted subsequent performance but strongly predicted social desirability scores. This pattern was not found for the partitioned scores of a cognitive test. Study 3 directly compared personality test scores and performance ratings of applicants (n = 97) to those of incumbents (n = 318) in a customer service job. Departures from linearity was observed in the applicant but not in the incumbent sample. Effects of applicant distortion on the validity of personality tests are especially concerning when validity decay increases toward the top of the distribution of test scores.
