Implications of shift work and language bias on overt and covert integrity tests

This study examined the difference in scores on overt and covert personality-based integrity tests between individuals who work a shift work schedule and those who do not. The study also looked at the difference in integrity test scores between individuals whose primary learned language is English and those for whom English is not the primary learned language. Fifty-five participants were pooled from California State University, Fullerton, social media sites, Linkedln and Facebook, and direct solicitation. Participants took an online questionnaire consisting of five surveys: The California Adult Q-Set, The Substance Abuse, Production Loss, and Interpersonal Problems Inventory, The Workplace Friendship Scale, a Measure of Workplace Deviance, and demographics.;Results did not support the hypotheses and showed no significant difference in overt integrity scores based on shift work type or primary language learned. However, it was found that those individuals who did work the night shift were significantly higher in "agreeableness". This aspect of the Five Factor Model of personality correlates well with integrity tests and supports prior research that shift workers have specific personality traits. Differences were also found on individual personality items. Between shift work types, these variances indicate differences in interpersonal communication. When comparing English as a primary or ancillary learned language, the variances indicated differences in self-confidence.
