 Hypothesis: It is hypothesized that patients in Transference Focused Psychotherapy TFP will manifest differential responses to the treatment, depending upon pre-treatment patient psychological and psychiatric characteristics. The investigators expect that some patients will show significant positive changes in symptoms, work, and social functioning at the end of 18 months, and that these positive changes will manifest in psychological and neuropsychological measures. The investigators will investigate the pre-treatment psychological variables e.g. trait sociability, constraint, and negative affect and neuropsychological functioning executive attention, capacity to inhibit behavior, memory functioning that will be predictive of patient improvement with treatment at the end of 18 months. By the end of the treatment, the investigators expect some patients to approach normal levels of enjoyment and enrichment of their experiences in work and social functioning. As all analyses will occur at the end of the study, response to TFP will not be assessed during the course of treatment. Therefore, patients will not be moved to a different intervention during the course of the study.
