Abstract

Psychological screening has become commonplace in a number of occupational groups. With the growing popularity of screening and the relative scarcity of appropriate personality measures, re‐screening individuals with the same inventory is frequent. This paper examines the effect of re‐screening with the Minnesota Multiphasic Personality Inventory (MMPI) on contract workers (n = 1,997) from the nuclear power industry. Participants completed the Inventory as a part of a routine screening procedure. Each participant provided several profiles as a result of regular employment cycles. Although the differences are generally small, some scales show large enough mean changes to warrant concern when interpreting the profiles of those who have taken the profile multiple times. Although scale reliabilities tend to increase, the usefulness of the Inventory appears to decrease with an increasing number of administrations. The effect is one of increasing normality of test profiles. One interpretation of the results is that candidates for jobs become “test‐wise,” and the scores are the result of a combination of responses to the repeated assessment. It becomes increasingly difficult to identify unfit employees with the Inventory. Given these results, further research on retesting effects of the Inventov, as well as other personality measures, is indicated.
