Revisions to the posttraumatic stress disorder (PTSD) diagnostic criteria in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013) clarify that secondary exposure can lead to the development of impairing symptoms requiring treatment. Historically known as secondary traumatic stress (STS), this reaction occurs through repeatedly hearing the details of traumatic events experienced by others. Professionals who work therapeutically with trauma victims may be at particular risk for this exposure. This meta-analysis of 38 published studies examines 17 risk factors for STS among professionals indirectly exposed to trauma through their therapeutic work with trauma victims. Small significant effect sizes were found for trauma caseload volume (r = .16), caseload frequency (r = .12), caseload ratio (r = .19), and having a personal trauma history (r = .19). Small negative effect sizes were found for work support (r = -.17) and social support (r = -.26). Demographic variables appear to be less implicated although more work is needed that examines the role of gender in the context of particular personal traumas. Caseload frequency and personal trauma effect sizes were moderated by year of publication. Future work should examine the measurement of STS and associated impairment, understudied risk factors, and effective interventions.

BackgroundIn adult correctional facilities, correctional officers (COs) are responsible for the safety and security of the facility in addition to aiding in offender rehabilitation and preventing recidivism. COs experience higher rates of job stress and burnout that stem from organizational stressors, leading to negative outcomes for not only the CO but the organization as well. Effective interventions could aim at targeting organizational stressors in order to reduce these negative outcomes as well as COs’ job stress and burnout. This paper fills a gap in the organizational stress literature among COs by systematically reviewing the relationship between organizational stressors and CO stress and burnout in adult correctional facilities. In doing so, the present review identifies areas that organizational interventions can target in order to reduce CO job stress and burnout.MethodsA systematic search of the literature was conducted using Medline, PsycINFO, Criminal Justice Abstracts, and Sociological Abstracts. All retrieved articles were independently screened based on criteria developed a priori. All included articles underwent quality assessment. Organizational stressors were categorized according to Cooper and Marshall’s (1976) model of job stress.ResultsThe systematic review yielded 8 studies that met all inclusion and quality assessment criteria. The five categories of organizational stressors among correctional officers are: stressors intrinsic to the job, role in the organization, rewards at work, supervisory relationships at work and the organizational structure and climate. The organizational structure and climate was demonstrated to have the most consistent relationship with CO job stress and burnout.ConclusionsThe results of this review indicate that the organizational structure and climate of correctional institutions has the most consistent relationship with COs’ job stress and burnout. Limitations of the studies reviewed include the cross-sectional design and the use of varying measures for organizational stressors. The results of this review indicate that interventions should aim to improve the organizational structure and climate of the correctional facility by improving communication between management and COs.

Historically, dance medicine and science has focused on the physical aspects rather than the psychological aspects of dance injury. Psychological variables, however, have been shown to influence the occurrence of injury and post-injury outcomes. The purpose of this review was to examine the dance psychology literature and determine the specific psychological factors reported to be associated with the incidence, frequency, and outcome of dance injuries. A systematic literature search was conducted using SPORTDiscus, MEDLINE, CINAHL, and PsycINFO. All retrieved articles were screened based on criteria developed a priori, and selected articles were subsequently assessed for quality. Thirteen studies met the inclusion and quality assessment criteria. Psychological factors associated with both risk and outcome of dance injury included the following: stress, psychological distress, disordered eating, and coping. Factors associated only with risk of injury were sleep, personality, and social support. The results suggest that psychological variables can affect both the incidence and outcome of dance injury among dancers. Therefore, it is critical to gain a well-rounded, thorough understanding of all the factors, including psychological, that have a negative impact on dancers with respect to dance injury. The findings are discussed in terms of the utility of including psychological assessment and intervention, such as cognitive behavioral therapy, when implementing preventative and treatment measures in dance schools and companies.

The lateral entorhinal cortex (LEC) is thought to bind sensory events with the environment where they took place. To compare the relative influence of transient events and temporally stable environmental stimuli on the firing of LEC cells, we recorded neuron spiking patterns in the region during blocks of a trace eyeblink conditioning paradigm performed in two environments and with different conditioning stimuli. Firing rates of some neurons were phasically selective for conditioned stimuli in a way that depended on which room the rat was in; nearly all neurons were tonically selective for environments in a way that depended on which stimuli had been presented in those environments. As rats moved from one environment to another, tonic neuron ensemble activity exhibited prospective information about the conditioned stimulus associated with the environment. Thus, the LEC formed phasic and tonic codes for event-environment associations, thereby accurately differentiating multiple experiences with overlapping features.DOI: http://dx.doi.org/10.7554/eLife.28611.001
