A Partial Test of Moffitt’s Developmental Taxonomy: Examining the Role of Genetic Risk

Abstract

A developing line of research indicates that behavioral patterns associated with the typologies identified in Moffitt’s developmental taxonomy may be influenced by genetic factors. Based on these findings, the current study examines whether Moffitt’s etiological explanations of life-course persistent offenders, adolescence-limited offenders, and abstainers have merit after controlling for genetic influences. To do so, a sample of twins drawn from the National Longitudinal Study of Adolescent Health were examined. The results revealed that genetic influences significantly predicted entry into each of the typologies identified by Moffitt even after controlling for theoretically relevant factors. Implications of the findings and suggestions for future research are discussed.
