Expectancies for drinking and excessive drinking among Mexican Americans and non-Hispanic whites.

This study was designed to identify the expectancies held by Mexican Americans toward the drinking of alcoholic beverages as well as toward excessive drinking. Random samples of 534 Mexican American and 616 non-Hispanic White residents of San José, California and of San Antonio, Texas were interviewed over the telephone. Mexican Americans were found to have unique expectancies toward drinking of alcoholic beverages and toward excessive drinking that differed from those held by non-Hispanic Whites. In addition, Mexican Americans expected the various outcomes in greater proportion than non-Hispanic Whites and the Mexican American respondents classified as high in acculturation tended to respond in a manner similar to that of non-Hispanic White respondents. Multivariate analyses of variance with common (across ethnic groups) factor scales with ethnicity, gender, and drinking status as independent variables showed main effects for drinking status and for ethnicity. The group differences in expectancies identified here support the need for culturally appropriate interventions that target group-specific beliefs.
