Show morePhysical and sexual abuse during childhood can have long lasting consequences such as posttraumatic stress disorder (PTSD). Prolonged Exposure (PE) is an established and effective guideline treatment for PTSD. Nevertheless, a considerable number of patients drop out from treatment or do not (completely) recover from PTSD during PE. It has been suggested that patients with PTSD resulting from childhood abuse are specifically at risk for suboptimal treatment outcomes. We carried out a randomized controlled trial with 149 patients with childhood abuse-related PTSD comparing PE with two innovations: intensified PE (iPE) and skills training in affective and interpersonal regulation followed by PE (STAIR+PE). We found that all treatments were safe and resulted in large improvements in PTSD symptoms. iPE and STAIR+PE did not improve treatment outcomes of PE, although iPE led to faster symptom improvements. Not all patients benefitted from the allocated treatment, but we found no contra-indications for the treatments. We found that a combination of patient characteristics was predictive of a larger effect size of PTSD symptom improvement in PE and iPE or STAIR+PE. We conclude that the three forms of exposure therapy were effective treatments for patients with childhood abuse-related PTSD. Show less

Show moreThe studies in this thesis concentrate on memory for an emotional event, with a specific focus on completeness, consistency and accuracy of emotional memories and their predictors. In doing so, both field and laboratory studies were conducted. The results show that overall, memory for emotional events is fairly complete and consistent over time. Still, the human memory is sometimes incomplete and prone to inaccuracies and inconsistencies. Maybe an elephant never forgets, people occasionally do! Emotional state, psychiatric status and psychological variables, with the exception of (peri) traumatic dissociation, did not have a strong influence on completeness, consistency and accuracy of memory for emotional events.
