Empirical examination of long-term and intensive psychodynamic psychotherapy for severely disturbed patients.

This study examines the effectiveness and efficiency of intensive psychodynamic psychotherapy for severely impaired patients. 104 patients in four public mental health centers underwent intensive psychodynamic psychotherapy. The number and duration of psychiatric hospitalizations were monitored for these patients from one year before therapy to eight years after. Several outcome variables were measured every six months, six times in total over two and a half years, using a longitudinal design. A multi-level analytic approach was applied to account for repeated measurements and missing data. Significant improvement was found in all three symptomatic outcome measures (SCL-90, OQ-45, BDI) throughout treatment. The numbers of psychiatric hospitalizations and psychiatric hospitalization days decreased significantly from the level they were in the year before the start of psychodynamic treatment to three years after the start of treatment. These results were maintained for at least up to eight years. After capitalization, the overall cumulative 127.47-day decrease in hospitalization days equals savings of 115,850 NIS. The average cost of treatment after capitalization was 26,770 NIS. The insurer's estimated direct savings is 89,080 NIS (24,054 $). These findings support the hypothesis that psychodynamic psychotherapy is clinically effective and economically efficient for severely impaired patients.
