초록

This study aimed to identify the factors influencing delinquency among multicultural adolescents and to determine the most appropriate statistical model for analyzing these variables. Using data from the Multicultural Adolescents Panel Study in Korea, this study examined the effects of parental supervision, delinquent peers, and bicultural acceptance attitudes on delinquency by applying and comparing five regression models: linear, Poisson, negative binomial, zero-inflated Poisson, and zero-inflated negative binomial regressions. The delinquency variable violated the assumptions of normality and homoscedasticity and exhibited overdispersion and excessive zeros. Among the five models, the zero-inflated negative binomial regression showed the best fit based on AIC, BIC, likelihood ratio test, and Wald test results. Furthermore, the zero-inflated negative binomial model addressed overdispersion more effectively than the negative binomial model. These findings suggest that the zero-inflated negative binomial regression model is most suitable for analyzing delinquency among multicultural adolescents when the outcome variable has unequal means and variance and a high proportion of zeros.
