Psychopathy across the lifespan: A five-factor model approach
Abstract
Although psychopathy is assumed to persist across much of the lifespan, evidence suggests that psychopaths show consistent decreases in overt criminal activities as they age. Similarly, although relatively stable across long periods of time, personality traits also show age-related changes in absolute levels. The current investigation examines whether age-related changes in basic traits can account for age-related changes in psychopathy. Using data from the NEO-PI-R in a large sample spanning ages 15 to 70, predictions about mean psychopathy levels are derived as a function of age. These predictions are tested against observed levels of psychopathy at various ages. Further, this study tests whether the differential declines across mean Factor 1 and Factor 2 psychopathy scores are due to differential declines in the specific traits associated with each factor. The current study adds to a body of research suggesting that psychopathy can be understood as a constellation of maladaptive personality traits.
