Similarities and differences between perceptions of peer delinquency, peer self-reported delinquency, and respondent delinquency: An analysis of friendship dyads

• Peer self-reported delinquency doesn’t reflect respondent reports of peer delinquency.
• Perceptions of peer delinquency largely reflect respondent self-reported delinquency.
• Peer self-reported delinquency is distinct from respondent self-reported delinquency.

PurposeDespite the peer delinquency measurement debate having profound implications for research, looming questions remain about the validity of various forms of peer delinquency operationalizations. This study examines whether perceptions of peer delinquency form identical latent constructs to both respondent and peer self-reported delinquency.MethodsUsing a dyadic dataset of friendship pairs, confirmatory factor analysis and model comparison tests are used to determine the degree of similarity between perceptions of peer delinquency, respondent self-reported delinquency, and peer self-reported delinquency.ResultsPeer self-reports and respondent perceptions of peer delinquency load on unique constructs across a number of different behaviors. For most behaviors, respondent perceptions of peer delinquency and respondent self-reports load on separate constructs. Results further indicate that respondent and peer self-reported delinquency are separate latent constructs. Finally, the strength of the association between respondent and peer delinquency is substantively smaller in magnitude, by as much as a factor of three in some instances, when peer delinquency is measured via peer self-reports in place of respondent perceptions.ConclusionsReports of peer delinquency provided directly from peers demonstrate strong discriminant validity in relation to self-reported delinquency, while perceptions of peer delinquency demonstrate poorer discriminant validity, particularly for theft and violence constructs.
