MMPI Patterns of Shoplifters within a College Population

Abstract

The hypothesis of an interaction between personality and shoplifting behavior was supported. A shoplifting questionnaire and the MMPI were administered to 170 undergraduates. The respondents were grouped according to three behavioral categories—never shoplifted, shoplifted once, shoplifted many times. From each category 20 profiles were analysed. Analyses showed significant profile differences. Shoplifters had more standard scores two standard deviations above the mean. Subscales measuring Hypochondriasis, Psychopathic Deviancy, Masculinity/Femininity Interest Patterns, and Mania differentiated all groups. The subscale, sex, and behavioral grouping interaction was significant. The chronic shoplifter's personality was described as hostile, deceitful, emotionally shallow, impulsive with delinquent tendencies and high energy levels. It was demonstrated that personality was an important variable to be considered in shoplifting behavior. The MMPI was recommended as a screening instrument for shoplifting behaviors.
