This study examined the relationship between aspects of social capital and self-reported delinquency among Turkish juveniles by using a secondary dataset, which is a part of the European Youth Survey. The survey was conducted among tenth graders in 2007 in Bağcılar, Istanbul. The dependent variable of this study, delinquency, was divided into two groups, minor and major, according to the stipulations of the Turkish Penal Code. Social capital was measured by assessing adolescents’ reports of their direct interactions with their parents, peers and community. In order to predict the likelihood of major and minor delinquency independently, two different subsets (N: 1879 and 1837, respectively) of the data set were used. The findings of the multivariate analyses suggest that a low level of social capital contributed significantly to Turkish juveniles’ engagement in major and minor delinquent activities. Among the social capital items, adolescents’ affiliation with delinquent peers had the strongest correlation with both dependent variables.

Marijuana is the most prevalent illicit drug used in the world and among Turkish juveniles. Although studies have examined marijuana use among Turkish juveniles, none has tested Hirschi's social bonding theory, one of the most frequently tested and applied criminological theories in the United States and other Western and developed countries. This study investigated the empirical validity and generalizability of Hirschi's theory to juveniles' marijuana use in Turkey, a non-Western and developing country. Data on 2,740 Turkish tenth grade students from the 2006 Youth in Europe survey were used. Results from binary logistic regression analyses were generally consistent with the propositions of Hirschi's theory and the findings of previous empirical studies. Regarding the attachment component of the theory, Turkish juveniles who lived in two-parent families and those who were closely monitored by their parents were less likely to have tried marijuana. In addition, teens who were strongly attached to their school and religion were also less likely to have used the drug. As for the commitment component, language grade was negatively associated with marijuana use. None of the involvement items had significant effects on marijuana use in the predicted direction. Participation in club sports had a positive effect on marijuana use. Belief items, such as acceptance of societal norms, values, and rules, had the predicted inhibiting effects on teens' marijuana use. Of the six sociodemographic/controls included in the analyses, only gender had a significant effect; male students were more likely to have tried marijuana than the female peers. Policy implications of the results for adolescents, parents, and schools are discussed.
