NIDA's research into treatments for cocaine abuse has identified a variety
of effective treatments ranging from group drug counseling to individualized
psychotherapies. In a NIDA-funded clinical trial investigating the efficacy
of four types of treatment, patients who received group drug counseling
combined with individual drug counseling were more likely to reduce their
drug use than were patients who received group drug counseling alone or
in combination with psychotherapies that are used to treat addictions.
Patients who received combined individual and group drug counseling used
less cocaine than did patients who received other forms of treatment.
The NIDA Collaborative Cocaine Treatment Study involved 487 patients with
relatively low levels of psychiatric severity whose principal diagnosis
was cocaine dependence as defined by the Diagnostic and Statistical Manual
of Mental Disorders. The drug counseling therapies evaluated in the multisite
study are specifically designed to treat drug use; the psychotherapies-supportive-expressive
therapy and cognitive therapy-are less focused on drug use. The study
involved patients recruited at five sites-the University of Pennsylvania
in Philadelphia; the Western Psychiatric Institute and Clinic at the University
of Pittsburgh; Massachusetts General Hospital in Boston; McLean Hospital
in Belmont, Massachusetts; and Brookside Hospital in Nashua, New Hampshire.
Each research center provided four treatments: group drug counseling alone,
group drug counseling combined with individual drug counseling, group
drug counseling combined with cognitive therapy, or group drug counseling
combined with supportive-expressive therapy. Each of the 487 patients
was randomly assigned to one of the therapies. Treatment results were
evaluated through patient self-reporting, weekly observed urine testing,
and the Addiction Severity Index-an interview-based assessment used to
measure treatment outcome. During each of the 6 months of treatment, and
at 3 months and 6 months after treatment ended, patients who received
combined individual and group drug counseling used less cocaine and drugs
overall than did patients who received other forms of treatment. A higher
percentage of combined drug counseling patients were able to achieve abstinences
of 1, 2, and 3 months than were patients in the other study groups. During
the 6 months after treatment ended, 38 percent of patients who completed
combined counseling treatment maintained drug-free periods of 3 consecutive
months compared with 27 percent of patients treated with group counseling
alone, 23 percent of patients treated with cognitive therapy plus group
counseling, and 18 percent of patients receiving supportive-expressive
therapy plus group counseling. In addition, patients who received combined
drug counseling showed more improvement in Addiction Severity Index ratings
than did patients receiving other treatments. "These results underline
the valuable role of well-designed drug counseling in treating drug abuse.
More specifically, this study demonstrates the effectiveness that combined
counseling therapies can have in treating cocaine addiction," notes Dr.
Jack Blaine of NIDA's Division of Treatment Research and Development.
"The success of combined drug counseling treatment compared with the psychotherapies
may be due to the fact that drug counseling delivers a message that is
simple and strong-stay away from the situations where you use drugs and
the people you use drugs with. The counselors at all sites involved in
our study were able to deliver that message effectively," says Dr. Paul
Crits-Christoph of the University of Pennsylvania, who coordinated the
multicenter study. Criteria for Success "The success of combined drug
counseling compared with other treatments is the result of the nature,
intensity, and quality of counseling," Dr. Crits-Christoph says. "We paid
a great deal of attention to selecting and training counselors, all of
whom had extensive previous experience treating patients with substance
abuse disorders." The counselors and psychotherapists received more than
a year of training in standardized therapy using published manuals, and
were evaluated during training and certified prior to participation in
the collaborative treatment study. Group drug counseling, given to all
study participants, consisted of weekly sessions for the full 6 months
of the study and individual meetings with the group counselor once per
month during a 3-month "booster" phase following the 6 months of active
treatment. Patients in individual drug counseling and psychotherapy treatments
participated in twice-weekly sessions during the first 3 months, weekly
sessions during the second 3 months, and monthly meetings during the booster
phase. Group drug counseling treatment involved an initial 3-month phase
during which patients were educated about the concepts in recovery from
addiction, and a second 3-month phase that involved open group discussions
focusing on patients helping each other solve problems encountered in
recovery. Individual drug counseling focused on helping patients achieve
and maintain abstinence through behavioral changes such as avoiding situations
that trigger drug use. Group drug counseling and individual drug counseling
encouraged patient involvement in self-help and support groups such as
Cocaine Anonymous outside of scheduled treatment sessions. Cognitive therapy
involved identifying the underlying beliefs related to a patient's drug
use. Therapists worked with patients to evaluate the advantages and disadvantages
of their beliefs. They also employed role-playing, behavioral experiments,
and scheduling and monitoring activities. Supportive-expressive therapy
involved identifying interpersonal conflicts that relate to a patient's
drug use. Therapists helped patients interpret the role that these conflicts
play in drug use and problems encountered in stopping drug use. Because
treatment and training were based on published manuals, it may be possible
for other treatment programs to achieve similar results, Dr. Crits-Christoph
notes. "If other programs can apply these tools with the intensity that
characterized this study, their outcomes should be similarly successful."
