The current study evaluated the efficacy of cocaine abuse counseling a
lone as a strategy to reduce HIV-related sexual risk behaviors. Partic
ipants were 232 cocaine-abusing or dependent individuals who received
up to 26 weeks of Matrix counseling but no formal HIV-prevention inter
ventions, One hundred fifty-seven (67.6%) participants completed asses
sments at admission, during treatment, and at 6 months following admis
sion. Participants located for follow-up were significantly more likel
y to be Caucasian, to be better educated, and to complete longer treat
ment episodes than those not located. Main study findings indicated a
statistically significant association between safer sex behavior and c
ompletion of a cocaine abuse counseling episode (chi(2)(2, n = 157) =
6.25, p < .05). Participants who completed counseling were more likely
to change to safer sex or maintain safer sex over the 6-month period
than participants who terminated counseling prematurely. The primary m
ethod for reducing sexual risk involved overall decreases in reported
numbers of partners (Partners(baseline) = 532, SD = 6.25; Partners(6 M
onths) = 2.47, SD = 2.62; F(1, 132) = 36.32, p < .001) among this grou
p of mostly heterosexual (89.9%), Caucasian (69.0%), crack cocaine use
rs (65.6%). We concluded that cocaine abuse counseling is a powerful i
ntervention for reducing HIV-related sexual behaviors in this group at
high risk for exposure to HIV. Study findings suggested that efforts
to evaluate HIV prevention programs must also account for the effect o
f drug counseling.
