A review of 2,647 studies of posttraumatic stress disorder (PTSD) yielded 476 potential candidates for a meta-analysis of predictors of PTSD or of its symptoms. From these, 68 studies met criteria for inclusion in a meta-analysis of 7 predictors: (a) prior trauma, (b) prior psychological adjustment, (c) family history of psychopathology, (d) perceived life threat during the trauma, (e) posttrauma social support, (f) peritraumatic emotional responses, and (g) peritraumatic dissociation. All yielded significant effect sizes, with family history, prior trauma, and prior adjustment the smallest (weighted r = .17) and peritraumatic dissociation the largest (weighted r = .35). The results suggest that peritraumatic psychological processes, not prior characteristics, are the strongest predictors of PTSD.

Assessment of mindfulness by self-report: the Kentucky inventory of mindfulness skills.

The present study describes the development of a short, general measure of experiential avoidance, based on a specific theoretical approach to this process. A theoretically driven iterative exploratory analysis using structural equation modeling on data from a clinical sample yielded a single factor comprising 9 items. A fully confirmatory factor analysis upheld this same 9-item factor in an independent clinical sample. The operational characteristics of the Acceptance and Action Questionnaire (AAQ) were then examined in 8 additional samples. All totaled, over 2,400 participants were studied. As expected, higher levels of experiential avoidance were associated with higher levels of general psychopathology, depression, anxiety, a variety of specific fears, trauma, and a lower quality of life. The AAQ related to more specific measures of avoidant coping and to self-deceptive positivity, but the relation to psychopathology could not be fully accounted for by these alternative measures. The data provide some initial support for the model of experiential avoidance based on Relational Frame Theory that is incorporated into Acceptance and Commitment Therapy, and provides researchers with a preliminary measure for use in population-based studies on experiential avoidance.

Measuring experiential avoidance: A preliminary test of a working model

Do we consciously cause our actions, or do they happen to us? Philosophers, psychologists, neuroscientists, theologians, and lawyers have long debated the existence of free will versus determinism. In this book Daniel Wegner offers a novel understanding of the issue. Like actions, he argues, the feeling of conscious will is created by the mind and brain. Yet if psychological and neural mechanisms are responsible for all human behavior, how could we have conscious will? The feeling of conscious will, Wegner shows, helps us to appreciate and remember our authorship of the things our minds and bodies do. Yes, we feel that we consciously will our actions, Wegner says, but at the same time, our actions happen to us. Although conscious will is an illusion, it serves as a guide to understanding ourselves and to developing a sense of responsibility and morality. Approaching conscious will as a topic of psychological study, Wegner examines the issue from a variety of angles. He looks at illusions of the will -- those cases where people feel that they are willing an act that they are not doing or, conversely, are not willing an act that they in fact are doing. He explores conscious will in hypnosis, Ouija board spelling, automatic writing, and facilitated communication, as well as in such phenomena as spirit possession, dissociative identity disorder, and trance channeling. The result is a book that sidesteps endless debates to focus, more fruitfully, on the impact on our lives of the illusion of conscious will.

Dissociation is a lack of the normal integration of thoughts, feelings, and experiences into the stream of consciousness and memory. Dissociation occurs to some degree in normal individuals and is thought to be more prevalent in persons with major mental illnesses. The Dissociative Experiences Scale

This study investigated physical education Facebook social media platforms to analyze comments by in-service teachers regarding their perceptions and experiences using competitive activities during secondary physical education classes. The last 5 years’ worth of initial postings and successive comments by a member and group members were examined. The community of practice framework guided this study. Data were compared with appropriate practice in sport. Over 745 lines of data, teachers’ responses were analyzed using NVivo (version 10.0). The first theme focused on the real game and the athlete. The second theme discussed separating genders; this theme had two subthemes, including (a) skill and gender: coed is great if you have skill and (b) gender-specific activities. The third theme focused on inappropriate activities, toughening up students, and that keeping score is fun. Results indicated teachers’ shared and conflicted perceptions that involved skill and gender during competitive activities.
