Research on Latino parental influences consistently points to the critical role that the attitudes and behaviors of parents play in predicting early use of substances by their children (Coombs, Paulson, & Richardson, 1991; Department of Health and Human Services, 1995; Hawkins, Catalano, & Miller, 1992; Hernandez & Lucero, 1996; Johnson & Johnson, 1999; Scheier, Botvin, & Miller, 1999; Sealy, 2000; Vega, Kourney, Zimmerman, & Gil, 1995). Researchers have emphasized that adolescent support networks may be more important in explaining drug use behavior than the individual characteristics of the adolescents themselves (Krohn & Thornberry, 1993; Wallace, 1999). Latino parental influence and quality of the parent-child relationship were critical predictors in the initiation and experimentation of alcohol, tobacco, and other drug use among high-risk youth (Coombs et al., 1991; Hawkins et al., 1992).
