Methods: The representative sample in this study consisted of 3,561 adolescents (Mage = 12.5, 52% female) from 10 public schools on O‘ahu, Hawai‘i. Ethnically, the sample was 34% Asian American (Chinese, Japanese, Korean), 8% Caucasian, 29% Filipino, 29% Native Hawaiian/Pacific Islander, and 6% Other. Using multiple regression, we tested the interaction between parental emotional support (5-item scale) and negative life events (19-item checklist), and between parent-adolescent conflict (3-item scale) and negative life events, with substance use as the criterion. Gateway substance use (i.e., tobacco, alcohol, and marijuana use) was measured on a 7-point scale ranging from “Never Tried” to “Everyday Use”.
Results: For overall substance use, we found subgroup buffering effects (ps < .10 or lower) for parental support among Asian Americans, Native Hawaiians and other Pacific Islanders (NHOPIs), and Filipinos. We also found that parent-adolescent conflict had a significant effect on increasing the impact of life events on substance use among Filipinos and NHOPIs (ps < .0001). For NHOPIs, parental emotional support significantly reduced the impact of life stress on tobacco and marijuana use, while parent-adolescent conflict significantly increased the impact of life stress on the use of all substances. In contrast, both parental emotional support and conflict were not significantly related to substance use for Caucasian youth in the sample.
Conclusion: Consistent with prior research, our findings suggest that parental support buffers the effects of negative life events on adolescent substance use. Ethnic differences in the findings suggest the need for prevention interventions focused on NHOPI youth and their families. Specifically, the results suggest the need for culturally focused prevention programs that promote parental emotional support and reduce the impact of parent-adolescent conflict for NHOPI youth.
