The Sensitivity of the CPI Good Impression Scale for Detecting ‘Faking Good’ among Norwegian Students and Job Applicants

Abstract

This study assessed the sensitivity of the California Psychological Inventory's Good Impression scale in the detection of ‘faking good’ in Norway. The original development of the scale was replicated using Norwegian students (N = 248). Paired sample T‐tests revealed significant differences for 31 of the 40 items when scores from normal test conditions were contrasted with scores obtained under `fake good' instructions. Further, job applicants (N = 494) scored significantly higher on the Good Impression scale than students. Comparisons of mean scale scores between Norwegian and US student samples suggested that the Norwegian students displayed a more modest self‐presentation. The Commonality Scale of the CPI was employed to investigate differences in scale usage between these two cultures. The analyses suggested that the differences in the Good Impression scale observed between these two cultures could not be explained by differences in acquiescence tendencies. Results suggest that the Good Impression scale is able to capture response distortion in Norwegian personnel selection situations, but modification of some items is needed.
