Outcome and Outcome Trajectories of Personality Disordered Patients During and After a Psychoanalytic Hospitalization-Based Treatment

This study aims to identify different outcome trajectories in a psychoanalytic hospitalization-based treatment in a sample of 70 patients with personality disorders using a naturalistic 12 month follow-up design. Trajectory analysis identified four groups of patients, i.e., patients showing (a) high initial symptom levels and considerable and consistent improvement late in treatment (High-Low group; HL), (b) medium initial symptom levels and a quick and sustained response (Medium-Low group; ML), (c) medium initial symptom levels but without substantial improvement (Medium-Medium group; MM), and (d) low initial symptom levels without substantial further improvement during and after treatment (Low-Low group; LL). Further, data suggested that these four trajectories were related in theoretically meaningful ways to pre-treatment variables, such as anaclitic and introjective personality styles and trauma. Results are discussed in the context of other studies showing the need for differential treatment approaches based on pretreatment characteristics.
