This project explored two topics: how race interacts with temperament to predict externalizing behavior (1) and the association between parent stress with externalizing behavior and temperament (2) in children. From parent-reported questionnaires of 61 Philadelphia area children (3-10yrs), 3 generalized linear models showed that there was no significant interaction between sociability & race in predicting externalizing behavior and that higher parent perceived stress significantly correlates with lower sociability reporting and with higher externalizing behavior. Expanding on race's interaction with temperament, future research may entail using a larger, diverse sample size with a formal measure of discrimination (1). For parent stress, future directions include exploring more dynamic methods of reporting child temperament as well as further evaluating the interconnectedness of parent stress and child temperament, controlling for additional factors that influence stress.
