abstract = {Background: Police and security professionals are routinely exposed to potentially traumatic events as part of occupational duties, placing them at increased risk for post-traumatic stress and broader psychological difficulties. This study aimed to identify latent classes of proximal traumatic exposure among Portuguese police/security professionals and examine their associations with PTSD symptoms and general psychological distress. Methods: A cross-sectional online survey was conducted with Portuguese police/security professionals (N = 644). Latent class analysis (LCA) was applied to 17 indicators of potentially traumatic events coded as directly experienced or witnessed, derived from the Life Events Checklist for DSM-5. PTSD symptoms were assessed using the PTSD Checklist for DSM-5, and general psychological distress was assessed using the Brief Symptom Inventory. Exploratory receiver operating characteristic (ROC) analyses examined whether counts of proximal traumatic events could approximate the LCA-derived classes. Results: A three-class solution was identified, comprising low proximal exposure (37.3%), moderate proximal exposure (40.7%), and high proximal/cumulative exposure (22.0%) classes. The classes reflected a graded cumulative pattern of exposure across traumatic event categories, rather than clearly distinct qualitative configurations defined by specific event types. Higher exposure classes were associated with progressively higher PTSD symptoms and psychological distress, and these associations remained significant after adjustment for sociodemographic and occupational variables. Exploratory receiver operating characteristic (ROC) analyses showed that a simple count of proximal traumatic event categories closely approximated the empirically derived class structure within the present sample. However, the resulting thresholds are sample-specific, exploratory, and should not be interpreted as validated screening cutoffs. Conclusions: Proximal traumatic exposure among police/security professionals appears to follow a graded cumulative structure associated with increased PTSD symptoms and psychological distress. The person-centered analysis provided an empirical test of whether exposure was organized according to qualitatively distinct event configurations or primarily along a cumulative gradient. In this sample, cumulative exposure burden emerged as the dominant organizing dimension. The count-based approximation requires external validation before any screening or decision-making application can be considered. © 2026 by the authors.},

abstract = {Background: The aim of the present study was to identify eaters profiles using the latest advantages of Machine Learning approach to cluster analysis. Methods: A total of 317 participants completed an online-based survey including self-reported measures of body image dissatisfaction, bulimia, restraint, and intuitive eating. Analyses were conducted in two steps: (a) identifying an optimal number of clusters, and (b) validating the clustering model of eaters profile using a procedure inspired by the Causal Reasoning approach. Results: This study reveals a 7-cluster model of eaters profiles. The characteristics, needs, and strengths of each eater profile are discussed along with the presentation of a continuum of eaters profiles. Conclusions: This conceptualization of eaters profiles could guide the direction of health education and treatment interventions targeting perceptual and eating dimensions. © 2023 by the authors.},

abstract = {State Social Physique Anxiety (SPA), in contrast to Trait SPA, is triggered by specific situations that elicit SPA. To date, no research has used virtual reality (VR) to recreate a situation that may elicit State SPA. The purpose of this study is to validate a virtual environment (VE) that simulates an anxiogenic situation to induce State SPA in women with obesity and high SPA. The high SPA group consisted of 25 self-identified women living with obesity and high Trait SPA. The low SPA group consisted of 20 self-identified women with low SPA. All participants were immersed in a virtual swimming pool environment for 10 min using a virtual reality headset. After the immersion, State SPA and fear of being negatively judged felt during immersion were measured with self-report questionnaires. A questionnaire assessing unwanted negative side effects was administered before and after the immersion. Using an ANCOVA with Trait SPA as covariate, State SPA was found to be significantly higher in the high SPA group. Fear of being judged negatively was also significantly higher in the high SPA group. Unwanted negative side effects scores did not increase post-immersion in either group. This study documents the validity of a novel VE for inducing State SPA in women with obesity and high SPA. © 2023 by the authors.},

The sample consisted of 15 participants with SAD from Canada, 17 participants without SAD from Canada, 16 participants with SAD from Spain, and 21 participants without SAD from Spain.

As hypothesized, results showed that the experimental virtual environment induced a higher level of anxiety than the control environment among participants with SAD compared to those without SAD. The impact on anxiety of each socially threatening task performed during the experimental immersion was statistically significant. In terms of anxiety responses, no significant differences were found between participants from Canada and Spain.

abstract = {Purpose: Many school-age children and adolescents who stutter experience the fear of public speaking. Treatment implications include the need to address this problem. However, it is not always possible to train repeatedly in front of a real audience. The present study aimed to assess the relevance of using a virtual classroom in clinical practice with school-age children and adolescents who stutter. Methods: Ten children and adolescents who stutter (aged 9–17 years old) had to speak in three different situations: in front of a real audience, in front of a virtual class and in an empty virtual apartment using a head-mounted display. We aimed to assess whether the self-rated levels of anxiety while speaking in front of a virtual audience reflect the levels of anxiety reported while speaking in front of a live audience, and if the stuttering level while speaking to a virtual class reflects the stuttering level while speaking in real conditions. Results: Results show that the real audience creates higher anticipatory anxiety than the virtual class. However, both the self-reported anxiety levels and the stuttering severity ratings when talking in front of a virtual class did not differ from those observed when talking to a real audience, and were significantly higher than when talking in an empty virtual apartment. Conclusion: Our results support the feasibility and relevance of using a virtual classroom to expose school-age children and adolescents who stutter to a feared situation during cognitive behavioral therapy targeting the fear of public speaking. © 2021 Elsevier Inc.},
