Clients in outpatient methadone treatment (OMT) who abuse cocaine or alcoho
l are difficult to engage and retain in treatment. The impact a triple addi
ction to these drugs has on treatment was the focus of this study (N = 127)
. Admission characteristics, treatment response and retention were compared
among clients dependent on opiates only (O) opiates and alcohol (OA) opiat
es and cocaine (OC), or all three drugs (OAC). Findings indicate these grou
ps differ in admission needs assessment, session attendance, issues discuss
ed drug treatment, and development of counselor rapport, with the OAC group
being significantly more difficult to engage and retain in treatment.
