“…Based on these figures, it would seem that the ISTDP-based, time-limited, residential treatment programme is an approach that warrants consideration for patients who do not respond to standard treatment formats. This study thereby supports the conclusions drawn in two previous studies of the treatment programme (2,9) and extends our knowledge base by adding information on observer-based diagnostic changes, along with information on psychosocial changes and changes in use of psychotropic medications. In all assessment domains of the present study, results point in the same direction: high-intensity, residential treatment tailored to the needs of treatment-resistant patients appears both highly effective and efficacious.…”
