Does the measurement of peer deviance change the relationship between self-control and deviant behavior? An analysis of friendship pairs

PurposeThe measurement debate between social learning and self-control theories has predominantly focused on self-control, leaving an unexplored and equally important measurement controversy concerning the operationalization of the peer delinquency construct. This study addresses how self-control's relationship with deviant and criminal behavior changes when peer deviance is statistically controlled for using an indirect, perceptual measure or a self-report directly from a peer.MethodsData from 796 friendship pairs are used to estimate a series of regression models that regress respondent deviance onto indirect and direct peer deviance and attitudinal and behavioral self-control measures while controlling for elements of the social bond and demographic characteristics.ResultsWhen an indirect measure of peer delinquency is replaced with a direct measure from respondents’ friends, the relationships between self-control – attitudinal and behavioral measures – and deviance and criminal behavior are consistently larger. The use of a direct peer deviance measure does not prove the peer deviance-crime relationship spurious, but does substantially weaken the relationship between self-control and deviance and criminal behavior.ConclusionsThe strength of the relationship between self-control and deviant/criminal behavior is contingent on how peer deviance is operationalized, regardless of how self-control is measured (attitudinally or behaviorally).

► Self-control's effect strength depends on the measurement of peer delinquency
► Self-control is weaker when perceptual measures of peer delinquency are used
► Self-control is stronger when measures of peer delinquency come straight from peers
► True for attitudinal and behavioral self-control
► Perceptions of peer delinquency are distinct from actual peer delinquency
