It has been proposed that maximizing expectancy violation enhances the efficacy of exposure therapy. The clinical utility of expectancy violation remains unclear and it has not yet been studied in PTSD. We aimed to test whether explicitly focusing on expectancy violation leads to superior exposure outcomes.

Patients with posttraumatic stress disorder (PTSD) following childhood abuse (CA-PTSD) may have challenges in building interpersonal relationships, including working alliance. Phase-based treatment provides an opportunity to strengthen alliance prior to trauma-focused treatment.

Background And Objectives: Inhibitory Learning Theory (ILT) framework implies that in-session distress variability may promote extinction learning and thereby enhance exposure therapy efficacy. Thus far, research has mainly focused on in-session distress reduction. The aim of the current study was to assess whether in-session distress variability predicts next session PTSD symptom decline in PTSD patients receiving prolonged exposure (PE).

Recent studies indicated that Prolonged Exposure (PE) is safe and effective for posttraumatic stress disorder (PTSD). It is unclear whether PE also leads to a reduction in comorbid diagnoses. Data from a large randomized controlled trial ( = 149) on the effects of three variants of PE for PTSD were used.

Prolonged exposure (PE) is an effective treatment for post-traumatic stress disorder (PTSD). This study aimed to analyse the cost-effectiveness of three exposure-based treatments in patients with childhood abuse-related PTSD. A net-benefit analysis was conducted alongside a pragmatic randomized controlled trial with participants (= 149) randomized to three conditions: PE (48), intensified PE (i-PE, = 51), and phase-based PE [Skills Training in Affective and Interpersonal Regulation (STAIR) + PE, = 50].
