The Self-Report Delinquency Scale From the National Longitudinal Study of Adolescent to Adult Health Among At-Risk for Delinquency Youths.

Juvenile delinquency is a universal problem, with serious personal, economic, and social consequences that span national boundaries. Thus, cross-culturally valid and reliable measures of delinquency are critical to providing a better understanding of the causes, correlates, and outcomes of delinquency. The main aim of the present study was to examine the psychometric properties of a Portuguese version of the self-report delinquency measure items created for the National Longitudinal Study of Adolescent Health (Add Health). A sample (N = 412) of male (n = 200) and female (n = 212) at-risk for delinquency youths agreed to participate in the present study. The measure demonstrated satisfactory psychometric properties, namely in terms of its two-factor structure (violent and nonviolent delinquency), internal consistency, convergent validity, discriminant validity, criterion-related validity, and known-groups validity. Findings suggest the Add Health Self-Report Delinquency (AHSRD) is an interculturally valid and reliable measure of violent and nonviolent delinquency among at-risk male and female youths.
