Objective: To report on the effectiveness of a time-limited day-hospital crisis treatment for personality disorders (PDs) in a naturalistic setting.
Method: Archival data from 260 patients diagnosed with PDs (202 female, 58 male) who completed a 6-week day-hospital treatment program between 2012 and 2015 were analyzed. Treatment was available upon referral by psychiatrists at local emergency rooms and short-term hospitalization units. Pre-post change was assessed using the Outcome Questionnaire (OQ-45.2).
Results: Patients significantly improved during treatment on the total OQ-45.2 scale and its 3 subscales. Pre-post changes yielded large effect sizes for the total OQ-45.2 scale and the Symptom Distress subscale, and moderate effect sizes for the Interpersonal Relations and Social Role subscales. Reliable change was observed for 55% of patients for the total scale. Younger patients (18 to 24 y of age) showed larger improvements on social role satisfaction than patients over the age of 30. Overall improvement was larger for patients engaged in social participation at the beginning of treatment.
Conclusions: This study conducted in a naturalistic setting suggests that a time-limited, 6-week day-hospital treatment program tailored to patients wiith PDs may be effective in reducing overall symptomatology in patients experiencing a crisis episode.
