Reduced ability to retrieve specific autobiographical memories is a well-defined feature of posttraumatic stress disorder (PTSD), and science-driven interventions have emerged to improve memory specificity and thereby symptoms. However, research in depressed samples indicates that the ability to flexibly move between retrieval of specific and general memory types (i.e., memory flexibility) may more accurately conceptualize autobiographical memory deficits in emotional disturbance. In this study, we evaluated memory specificity and memory flexibility in Iranian trauma survivors ( N = 63) with and without PTSD relative to community control participants. Trauma-exposed participants had experienced a serious road-traffic accident. Results indicated that individuals with PTSD experienced reduced memory specificity and memory flexibility relative to trauma-exposed participants and community control participants. A small sample size limits the strength of conclusions, although good statistical power was obtained. Findings suggest that reduced memory flexibility may be a transdiagnostic marker of emotional disturbance and support further development of memory flexibility interventions for PTSD.

Evidence from self-reports and laboratory studies suggests that recall of nontrauma autobiographical memories may be disturbed in posttraumatic stress disorder (PTSD), but investigations in everyday life are sparse. This study investigated unintentional nontrauma and trauma memories in trauma survivors with and without PTSD ( N = 52), who kept an autobiographical memory diary for a week. We investigated whether unintentional nontrauma memories show an overgeneral memory bias and further memory abnormalities in people with PTSD, and whether unintentional trauma memories show distinct features. Compared to the no-PTSD group, the PTSD group recorded fewer nontrauma memories, which were more overgeneral, more often from before the trauma or related to the trauma, were perceived as distant, and led to greater dwelling. Trauma memories were more vivid, recurrent, and present and led to greater suppression and dwelling. Within the PTSD group, the same features distinguished trauma and nontrauma memories. Results are discussed regarding theories of autobiographical memory and PTSD.

Autobiographical memory distortions are a key feature of posttraumatic stress disorder (PTSD). In this proof-of-concept randomized controlled trial ( N = 43), we evaluated an autobiographical memory flexibility intervention, MemFlex. We aimed to determine whether the mechanism-focused intervention, which aims to improve autobiographical memory processes, may also affect other cognitive predictors of PTSD and potentially reduce PTSD symptoms in Iranian trauma survivors diagnosed with PTSD. Results indicated significant, moderate to large between-groups effect sizes in favor of MemFlex, relative to wait-list control, for the targeted cognitive mechanism of autobiographical memory flexibility and PTSD symptoms. A large, significant effect was also observed on maladaptive posttraumatic cognitions—a strong predictor of PTSD prognosis, which is a key target of high-intensity cognitive therapies for PTSD. Findings support future completion of a scaled-up trial to evaluate treatment efficacy of MemFlex for PTSD to determine whether MemFlex may offer a culturally adaptive, low-cost, low-intensity intervention able to improve cognitive mechanisms of PTSD.

This article reviews the literature on prevalence, associated features, assessment, and treatment of intrusive symptoms associated with posttraumatic stress disorder (PTSD). Research indicates that among trauma survivors, intrusive thoughts and imagery are quite common and distressing. It appears that early intrusions may be predictive of long-term distress and that avoidance and suppression can maintain intrusions. The treatment outcome literature for PTSD indicates that current cognitive behavioral treatments are effective in reducing intrusions. New data from a recent treatment outcome study for PTSD with comorbid panic attacks, using Multiple Channel Exposure Therapy, also suggest that this treatment is effective in significantly reducing intrusions.
