Study start date: September 1, 2001Actual date on which the first participant was enrolled.

Therapeutic Community (TC) treatment can be effective psychosocial modality for addiction, but premature dropout remains a major problem. Personality disorders are very common in residential programs, and TCs regard personality disturbance as core to all people with addiction. Severe personality dysfunction is associated with higher dropout rates from TCs, and adding cognitive-behavioral treatments may improve retention and outcome. We hypothesize that severe personality disturbance causes significant problems with an individual?s initial adjustment and effective utilization of TC processes and techniques. We predict that a behavioral therapy that targets personality pathology will result in better early retention and engagement than will a more standard addiction counseling approach. To begin to improve retention, TC research must begin to systematically evaluate the impact of adding interventions targeted at decreasing premature dropouts through controlled clinical trials. We have developed the first empirically tested treatment manual for the full range of personality disorders in substance abusers and propose to conduct a randomized clinical trial to evaluate the efficacy of Dual Focus Schema Therapy in comparison to Individual Drug Counseling as 6-month manualized individual behavioral therapy enhancements to the orientation/early treatment process of 100 TC residents. In addition to evaluating retention differences, we will analyze the rate and degree of change for these two conditions monthly and at 6, 12, 18, and 24-month follow-up for psychological indicators related to personality disorder and therapeutic processes related to the TC.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
100 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How treatments are given to participants
Participants receive different combinations of treatments to see how they work together. This approach helps researchers determine whether a combination of treatments is more effective than a single treatment alone.

Other Ways to Assign Treatments
Single-group assignment
: Everyone gets the same treatment.

Parallel assignment
: Participants are split into separate groups, each receiving a different treatment.

Cross-over assignment
: Participants switch between treatments during the study.

Sequential assignment
: Participants receive treatments one after another in a specific order, possibly based on individual responses.

Other assignment
: Treatment assignment does not follow a standard or predefined design.
