Crime Causation

A body of research has revealed that low self-control is one of the strongest and most consistent predictors of antisocial behaviors. As a result, there is great interest in identifying the factors that cause variation in levels of self-control. Much of this work has centered on identifying the effects that social factors, such as parental socialization, have on self-control. More recently, however, there has been research revealing that levels of self-control are scripted by genetic factors as well as environmental factors. The current study examines whether a polymorphism (5HTTLPR) in the serotonin transporter gene and exposure to delinquent peers are associated with levels of self-control. Analysis of the National Longitudinal Study of Adolescent Health indicates that the 5HTTLPR polymorphism interacted with a measure of delinquent peer affiliation to predict variation in self-control during adolescence and adulthood. Implications for theories of crime causation are discussed.

BackgroundPrior research has indicated that affiliation with delinquent peers activates genetic influences on delinquency during adolescence. However, because other studies have indicated that the socializing effects of delinquent peers vary dramatically across childhood and adolescence, it is unclear whether delinquent peer affiliation (DPA) also moderates genetic influences on delinquency during childhood.MethodThe current study sought to evaluate whether and how DPA moderated the etiology of delinquency in a sample of 726 child twins from the Michigan State University Twin Registry (MSUTR).ResultsThe results robustly supported etiological moderation of childhood delinquency by DPA. However, this effect was observed for shared environmental, rather than genetic, influences. Shared environmental influences on delinquency were found to be several-fold larger in those with higher levels of DPA as compared to those with lower levels. This pattern of results persisted even when controlling for the overlap between delinquency and DPA.ConclusionsOur findings bolster prior work in suggesting that, during childhood, the association between DPA and delinquency is largely (although not solely) attributable to the effects of socialization as compared to selection. They also suggest that the process of etiological moderation is not specific to genetic influences. Latent environmental influences are also amenable to moderation by measured environmental factors.

Adolescent Relationship

Previous research demonstrated the association between parent–adolescent relationship quality and deviant peer affiliation, but it is unclear whether this relation is mediated by other psychological and interpersonal variables, whether father– and mother–adolescent relationship quality have different pathways in predicting deviant peer affiliation, and whether gender moderates these associations. A sample of 543 students from grades 10 to 12 (42.7% male; age M = 16.2 years, SD = 1.0) was selected from a Chinese high school in Shenzhen, China. They provided demographic variables and completed self-report measures of father– and mother–adolescent relationship quality, self-control, friendship quality, and deviant peer affiliation. The results showed that lower father–adolescent relationship quality was associated with lower self-control, which in turn was associated with higher deviant peer affiliation. Mother–adolescent relationship quality did not have direct or indirect association with deviant peer affiliation. In addition, male and female adolescents had no significant difference in the associations between father– and mother–adolescent relationship quality, self-control, friendship quality, and deviant peer affiliation. Implications and limitations of these findings were discussed.

Grade Point

Girls consistently achieve higher grades than boys despite scoring lower on major standardized tests and not having higher IQs. Sex differences in non‐cognitive variables such as personality might help to account for sex differences in grades. Utilizing a large sample of 17‐year‐old twins participating in the Minnesota Twin Family Study (MTFS), we examined the roles of Achievement Striving, Self‐Control and Aggression on sex differences in grade point average (GPA). Each personality trait was a significant predictor of GPA, with sex differences in Aggression accounting for one‐half the sex difference in GPA and genetic variance accounting for most of the overlap between personality and GPA. Achievement Striving and Self‐Control moderated the genetic and environmental influences on GPA. Specifically, for girls but not boys, higher Achievement Striving and Self‐Control were associated with less variability in GPA and greater genetic and environmental overlap with GPA. For girls, certain personality traits operate to shape a context yielding uniformly higher GPA, a process that seems absent in boys. Copyright © 2008 John Wiley & Sons, Ltd.

Nonlinear Pattern

Previous research illustrating a robust, negative association between self-control and various forms of delinquent and criminal behavior has resulted in a more concentrated focus on the etiological development of self-control. The current study aims to contribute to this literature using a sample of twin and sibling pairs from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine genetic and shared environmental influences across levels of self-control. The results of modified DeFries–Fulker (DF) equations revealed that genetic and shared environmental influences were distributed in a nonlinear pattern across levels of self-control. Subsequent biometric quantile regression models revealed that genetic influences on self-control were maximized in the 50th and 60th percentiles, and minimized in the tails of the distribution. Shared environmental influences were nonsignificant at all examined quantiles of self-control with only one exception. The theoretical importance of utilizing genetically informed modeling strategies is discussed in more detail.
