Objective: This study examined the association between counseling rapport a
nd drug abuse treatment outcomes. Methods: Two cohorts of outpatients who w
ere being treated with methadone in four cities were studied. Cohort 1 comp
rised 354 patients in community-based nonprofit programs, and cohort 2 comp
rised 223 patients from a private for-profit program. Logistic regression a
nalyses were used to assess the importance of counseling rapport as a predi
ctor of drug use and criminality relative to treatment retention in the ind
ex treatment, satisfaction with treatment, and whether additional treatment
was received after the index treatment. Results: In both cohorts, ratings
made by counselors, during treatment, of therapeutic involvement and relati
onships with patients provided a useful measure of counseling rapport. A lo
wer level of rapport during treatment predicted worse post-index treatment
outcomes, including more cocaine use and criminality, both by itself and af
ter adjustment for treatment retention, satisfaction with treatment, and po
st-index treatment status. Counseling strategies were associated with the d
evelopment of counseling rapport. Conclusions: Counseling rapport is a vita
l part of the therapeutic process and helps explain why and when treatment
is effective. It contributes explicitly to the prediction of outcomes, apar
t from treatment retention, and accounts in part for the usual association
between treatment retention and outcomes.
