Imagery rescripting and extinction: Effects on US expectancy, US revaluation, and the generalization of fear reduction.

Exposure therapy consists of exposing patients to their fears and thereby diminishing their harm expectancies (i.e., extinction or expectancy learning).

Mental threat rehearsal increases fear generalization.

Background And Objectives: Fear generalization to harmless stimuli characterizes anxiety-related disorders, but much remains unknown about its determinants. Based on studies showing that mental imagery of threat can increase conditioned fear responding, we tested whether it also facilitates fear generalization, and whether threat inflation moderates this effect.

Methods: In a fear conditioning study, 120 participants first completed an acquisition phase, in which one of two pictures was followed by an aversive sound (human scream).

Changes in needle maneuver space and optimal insertion site for midline neuraxial puncture with progressive age: an analysis in computed tomography scans.

Introduction: We systematically describe the morphology and accessibility of interspinous spaces across age groups of patients. Our primary goal was to objectively estimate if the maneuver space for a virtual spinal needle changes with age. Our secondary goal was to estimate if the optimal site and angle for midline neuraxial puncture change with age.

The degree of safety behaviors to a safety stimulus predicts development of threat beliefs.

Safety behaviors are behavioral responses that aim to prevent or minimize an imminent threat when confronting a feared stimulus. Despite its adaptive purpose, preliminary evidence suggests that unnecessary safety behaviors to a safety stimulus induce threat beliefs to it. By allowing participants to engage in safety behaviors dimensionally, this study tested whether the degree of safety behaviors to a safety stimulus predicts the subsequent level of threat expectancies to it.

Childhood maltreatment and adulthood victimization: An evidence-based model.

There is ample evidence showing that childhood maltreatment increases two to three fold the risk of victimization in adulthood. Various risk factors, including posttraumatic stress disorder (PTSD) symptoms, dissociation, self-blame, and alcohol abuse are related to revictimization. Although previous research examined associations between risk factors for revictimization, the evidence is limited and the proposed models mostly include a handful of risk factors.
