Prebiotics as an adjunct therapy for posttraumatic stress disorder: a pilot randomized controlled trial.

Introduction: Posttraumatic stress disorder (PTSD) is a debilitating disorder characterized by intrusive memories, avoidance, negative thoughts and moods, and heightened arousal. Many patients also report gastrointestinal symptoms. Cognitive behavioral therapy (CBT) is an evidence-based treatment approach for PTSD that successfully reduces symptoms.

Evaluating self-efficacy as a treatment mechanism during an intensive treatment program for posttraumatic stress disorder.

Objective: Although traumatic exposures are common, only a small percentage of people exposed to trauma go on to develop posttraumatic stress disorder (PTSD). This phenomenon suggests that there may be psychological factors that influence posttraumatic recovery trajectories. Beliefs about one's ability to cope with traumatic events have been proposed as a mechanism of posttraumatic recovery.

Using network analysis to characterize clinical improvement during cognitive processing therapy.

Objective: Cross-sectional network studies find mixed results regarding changes in network structure as a response to treatment across disorders. This study characterized improvement in mental health following Cognitive Processing Therapy (CPT) for PTSD in veterans from the perspective of network psychometrics and explored how cross-sectional networks inform our understanding of PTSD recovery.

Methods: Veterans with PTSD participated in CPT-based intensive treatment programs (ITPs), offered in two-week (N = 635) or three-week (N = 457) formats.
