Objective: The aim of the study was to test the effectiveness of an eight-day (two-week) intensive treatment for PTSD within a public health care setting (open trial design).

Method: Eighty-nine patients were offered the choice between intensive treatment and spaced individual treatment, of which 34 (38.2%) chose the intensive format. Patients were assessed with self-report batteries and interviews at pre-treatment, start of treatment, post-treatment and three-month follow-up. Each day consisted of individual Prolonged Exposure therapy, Eye Movement Desensitization and Reprocessing therapy, group psychoeducation, and physical activity. Therapists rotated between patients.

Results: Between 55 and 62% of the patients showed a clinically significant change (recovery) in symptoms of PTSD, and the effect sizes were large (d = 1.38–1.52). Patients also showed reduction in symptoms of depression and anxiety, along with improved well-being and interpersonal functioning. Changes in social and work functioning were more ambiguous. There were no dropouts, attendance was high, and patients were highly satisfied with the treatment.

Conclusions: The intensive programme was an attractive and effective treatment option for patients with PTSD.

• More than a third of the patients referred to our clinic chose intensive over spaced treatment.
• Patients reported significant reductions in symptoms of PTSD, depression, and anxiety.
• None of the patients dropped out of treatment, and they reported high treatment satisfaction.”
