The purpose of the study was to examine and compare the health behaviors of adult childrenof alcoholics (ACOAs) and their non-ACOA peers within a university population. Subjects were 945 undergraduate students from a major university in the East. Three groups (ACOA,non-ACOA, and Unsure) were identified from subjects' responses to three direct questionsregarding parental drinking behaviors. Aquestionnaire was used to collect data for thestudy.Analysis of variance procedures revealed that ACOAs had significantly lower wellness scores (WS) than non-ACOAs.
