Tg. Brown et al., ALCOHOLICS ALSO DEPENDENT ON COCAINE IN TREATMENT - DO THEY DIFFER FROM PURE ALCOHOLICS, Addictive behaviors, 19(1), 1994, pp. 105-112
Although individuals who exhibit both alcohol and cocaine dependency a
re seen increasingly in traditional alcoholism rehabilitation settings
, their comparability with ''pure'' alcoholics is unclear. Sociodemogr
aphic, psychological, cognitive, and substance abuse status were, ther
efore, monitored in a group of alcoholics (n = 64) versus a group of c
ocaine dependent alcoholics (n = 82) on admission and just prior to di
scharge from 28-day multimodal treatment settings. At admission, cocai
ne-dependent alcoholics were younger, more likely to be unmarried, hav
e more extensive substance use histories as well as more frequent prio
r treatments than ''pure'' alcoholics. Additionally, members of both g
roups exhibited abnormalities on psychological indices. Both psycholog
ical and cognitive indices revealed significant between-group differen
ces which subsequent analyses found to be a confound of the marked age
discrepancy between groups. From admission to discharge, scores on bo
th psychological and cognitive indices declined significantly in both
groups. Urine assay data revealed a greater tendency for cocaine-depen
dent alcoholics to relapse during treatment. While the psychological a
nd cognitive data largely argue for the comparability of groups of pat
ients classified as ''pure'' alcoholics with those who are dependent o
n both alcohol and cocaine, the latter group may have more difficulty
in achieving abstinence during treatment. The interpretability of beha
vioral indices gathered only at treatment admission is questioned.
