This study examined the predictability of dysfunctional job behaviors among
law enforcement officers using 3 scales (Responsibility, Socialization, an
d Self-Control) of the California Psychological Inventory (H. G. Cough, 199
5) that were hypothesized to assess the construct of conscientiousness, and
3 construct-oriented life history indices (drug use, criminal, work). Law
enforcement officers were classified into disciplinary and control groups (
n = 109 each), using a matched-case control study design. Mean differences
between the 2 criterion groups on the 6 predictor variables were all statis
tically significant and in the hypothesized direction. The results are disc
ussed in the context of conscientiousness as an explanatory construct, the
relationship between life history and personality constructs, and methodolo
gical concerns in the development of construct-oriented life history indice
