A predictive validation study of the situational interview (SI) and the patterned behavioral description interview (PBDI) was conducted for the criterion of teamplaying behavior. Both the SI and PBDI were valid predictors (r=.41, .34, respectively). Only the SI, however, had incremental validity. Reasons for this finding are explained in terms of the development and scoring of SI items, conducting a pilot study, use of a panel who took notes, and the method of including/excluding interview applicants and questions for a validation study.
