Addiction programs are plagued with high dropout and relapse rates. A large proportion of patients suffering from addiction also suffer from personality disorders. A 30-day inpatient program based on intensive short-term dynamic psychotherapy was developed to address features of personality disorders such as anxiety regulation, emotion recognition, and handling of fear responses and projective processes. The hypothesis was that addressing comorbid symptoms of personality disorder might improve recovery from drug addiction. We used a pilot randomized controlled trial design with six-month follow-up of both cases and controls. Rates of remission, relapse and drop out were recorded at each time point. N-1 chi-squared (χ2) tests were conducted to examine the statistical significance of differences in outcomes in patients receiving the experimental treatment and controls. A control group of 20 patients and an experimental group of 42 patients were treated. Dropout: control group 40%; experimental group 23.8%. Sobriety at six months: control group 17.6%, experimental group 48.8%. Future study is warranted to examine intensive short-term dynamic psychotherapy's long-term effects, study moderators of effects, and study its efficacy using a randomized controlled design.
