In order to evaluate the effect of frequency of counseling sessions, we studied retention, cocaine use and craving, and psychiatric symptoms of 68 cocaine-dependent outpatients randomly assigned to twice weekly, once weekly, or biweekly sessions in a 12-week treatment program that utilized manual-based, individual cognitive behavioral psychotherapy. All participants were tested and monitored twice a week. Retention was comparable among treatment groups, and improvement was found regardless of counseling frequency. Cocaine use (urine toxicology and self-report), cocaine craving (VAS), and total psychiatric symptoms (SCL-90) decreased by modest but statistically significant (p < 0.05) amounts in all treatment groups. Findings suggest that cognitive behavioral therapy is effective in reducing cocaine use even if a less intensive schedule is used.
