Disturbed or impoverished relationships have been identified as a pred
ominant feature of adult children of alcoholics (ACOAs). Recently, the
concept of co-dependency has been advanced to depict the interpersona
l difficulties of these individuals, but lacks definitional rigor. The
notion that childhood experiences with parents are 'carried forward'
to affect attitudes and behaviors relevant to later intimate relations
hips is also consistent with attachment theory. This study examined th
e patterns of attachment of ACOAs as compared to adult children of non
alcoholics (ACONAs). A cross-sectional sample of 203 individuals atte
nding either a short term hospital based outpatient psychiatric progra
m or a community based alcoholism treatment program was included in th
is study. Results supported the hypothesis that female ACOAs had a dis
tinctive dysfunctional attachment profile. There were no significant d
ifferences in the attachment styles of male ACOAs as compared to ACONA
s, or male substance abusers as compared to non-abusers.
