Academic Achievement and Problem Behaviors among Asian Pacific Islander American Adolescents

Using data from the National Longitudinal Study of Adolescent Health, this study tests whether the relationship between academic achievement and problem behaviors is the same across racial and ethnic groups. Some have suggested that academic achievement may be a weaker predictor of problem behaviors among Asian Pacific Islander American (API) youth; that they can have high grades but still exhibit problem behaviors. This study finds that academic performance is a significant predictor of aggressive and nonaggressive delinquent offenses, gang initiation, sexual behaviors, and substance use, and that the relationship generally does not vary by race and ethnicity. Thus, there is little evidence that API youth are high achievers who are also engaging significantly in problem behaviors. The existing perceptions of API youth may be largely based on stereotype and ambivalence.

Longitudinal Effects of Perceived Maternal Approval on Sexual Behaviors of Asian and Pacific Islander (API) Young Adults

Data were obtained from the National Longitudinal Study of Adolescent Health to examine the longitudinal association between Asian and Pacific Islander (API) adolescents’ perceptions of maternal approval of their sexual activity and contraception use, and four sexual outcomes during young adulthood. The study includes a nationally representative sample of 1,195 API adolescents. Logistic regression analyses were used to estimate the associations between predictors (Wave I) and outcomes (Wave III), controlling for covariates. API adolescents who perceived that their mothers approved of their sexual activities were more likely to have engaged in sex before age 15, contracted HIV/Sexually Transmitted Diseases, had multiple sex partners, and paid money for sex during young adulthood. Findings highlight the need for parent–adolescent communication and parental involvement in preventing negative sexual health outcomes among API adolescents transitioning to young adulthood.
