The aim of this project is to investigate the effectiveness of phase-based trauma-focused therapy (PBT) and intensive trauma-focused therapy (I-TFT) for adult patients with PTSD related to childhood abuse.
We will carry out a RCT, randomizing 150 patients to receive either standard TFT, PBT or i-TFT. The effects will be assessed at two endpoints of treatment (4, 8 and 16 weeks) and after a 6 and 12 months follow-up in an intention-to-treat analysis.

The Dutch treatment guidelines recommend trauma-focused treatment (TFT) for PTSD. In TFT, patients are exposed to trauma reminders that they typically avoid, until their emotional reactions decline. This treatment has been found very effective for some patients but there is much room for improvement, particularly in PTSD related to childhood abuse (CA-PTSD). Symptom exacerbation, non-attendance and dropout rates of up to 40% have been observed in patients with CA-PTSD.
Two alternative treatments have been proposed. Firstly, TFT may be preceded by emotion regulation and interpersonal skills training. This is called phase-based treatment (PBT). The rationale is that patients with CA-PTSD have affect regulation and interpersonal problems that interfere with effective delivery of TFT. These problems are rooted in the detrimental developmental effects of abuse (often by an attachment figure). PBT indeed resulted in more favorable outcomes and fewer dropouts. In international guidelines, PBT was recently recommended as treatment of choice for patients with CA-PTSD and comorbidity.
Another innovative treatment is intensive TFT (i-TFT), which means delivering TFT in 4 instead of 16 weeks. The condensed format enhances learning and prevents the buildup of anticipatory anxiety, which in turn affects the patients' motivation. Patients with CA-PTSD are also characterized by high psychosocial stressors, leading to problems with treatment attendance and compliance. The condensed format may improve motivation, attendance and compliance. I-TFT was recently tested in a case series in patients with CA-PTSD and in a randomized controlled trial (RCT) with patients with adulthood-related PTSD. Both studies had very low dropout rates (0-3%) and fast recovery.
The aim of the current study is to investigate the (cost)effectiveness of two innovative forms of trauma-focused therapy for patients with CA-PTSD: phase-based therapy (emotion regulation skills training followed bij PE) and intensive PE (i-PE). The effects will be assessed post-treatment and after a 6 and 12 months follow-up in an intention-to-treat analysis. Results will be disseminated and included in treatment guidelines. The ultimate goal is to improve quality of care and contribute to treatment innovation for this severely ill target population.
