Zero-order Pearson correlations among study variables are shown in Table 2.Diagnosis of an AUD was significantly correlated with deviant peer affiliation, parental monitoring, and OPRM1 in the expected directions (p values < .01). OPRM1 was significantly correlated with deviant peer affiliation and parental monitoring, such that carriers of the G allele tended to have higher levels of deviant peer affiliation and lower levels of parental monitoring (p values < .05).
