This study used a community-wide survey of adolescents to compare adolescent perceptions of parental support, knowledge, and authoritative decision making in samples of Hmong and European Americans. Additional analyses considered variation in parental influence on adolescent outcomes across these groups. The results suggested that Hmong American youth perceived less parental support and knowledge and were less likely to report authoritative decision making with parents. Parental support and knowledge were associated with higher self-esteem and grade point average (GPA) and lowered risky health behaviors in both samples. Results also suggested that authoritative decision making by mothers was a more important predictor of adolescent GPA and risky behaviors for the European American adolescents.
