Cognitive-behavioral therapy (CBT) with exposure in virtual reality (VR) emerges as a promising intervention for treating speaking anxiety in pediatric populations. This pilot study tested if real-time avatar-based VR can elicit anxiety responses while remaining acceptable to youth who stutter. Method Twelve students who stutter (aged 9–18) were randomly assigned to a single training session conducted either (1) in VR with a realistic avatar controlled live by their SLP, or (2) in role-play with their SLP, before facing a real actor. We assessed system acceptability, anxiety levels and perceived self-efficacy. Results The VR system was well accepted and elicited physiological arousal comparable to real-life interactions. Although participants reported experiencing less anxiety during VR, skin conductance level showed higher arousal; suggesting a divergence between the subjective report and physiological response. Finally, one training session (either in VR or with the SLP) did not produce gains in self-efficacy or decrease in anxiety related to the final real-actor conversation. Conclusion This study demonstrates evidence that the potential use of immersive VR could represent an acceptable and viable complementary strategy for SLP treatment, that could control exposure parameters while evoking physiological responses similar to real-life contexts. The differences between subjective and physiological measures suggest that VR is inducing anxiety responses differently than it was perceived. Further research could investigate the use of VR as anxiety interventions for students who stutter and should be explored across multi-session studies to understand their therapeutic effect. © 2026 The Authors.},

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 = {Cognitive-behavioral therapy (CBT) with exposure and response prevention (ERP) is widely regarded as the gold-standard psychological treatment for obsessive–compulsive disorder (OCD). Inference-based cognitive behavioral therapy (I-CBT) represents a distinct cognitive approach that targets inferential confusion, defined as a reasoning process whereby imagined possibilities are treated as reflecting reality, without relying on deliberate exposure. The present study reports further mechanism-focused analyses from a previously published multicenter randomized controlled trial (Aardema et al., 2022; ClinicalTrials.gov Identifier: NCT01794156) comparing CBT with ERP, I-CBT, and mindfulness-based stress reduction (MBSR) for OCD. A total of 111 participants with a primary diagnosis of OCD were randomized to one of three treatment conditions. Across treatments, therapy was associated with significant reductions in inferential confusion and obsessive belief domains, whereas dispositional mindfulness did not show significant change. At the bivariate level, residualized changes in inferential confusion, obsessive belief domains, and mindfulness were associated with reductions in OCD symptoms. However, when examined concurrently using mixed-effects models, only reductions in inferential confusion accounted for unique symptom improvement over time. This association was consistent across modalities and remained robust after controlling for concurrent anxiety and depression. Sensitivity analyses indicated that psychotropic medication use did not account for this association; controlling for medication strengthened the independent contribution of inferential confusion (partial η2 ≈ .29). These findings indicate that inferential confusion was independently associated with symptom improvement in OCD across therapeutic approaches. © 2026 Elsevier Ltd},

abstract = {Background: The Telehealth Intervention Program for Older Adults (TIP-OA) was a volunteer-based phone support program for to older adults during the COVID-19 pandemic. While volunteer-based phone programs can be effective in providing mental health support, there is limited data on the predictors of response to such interventions. This study aimed to examine clinical and demographic predictors of response to the TIP-OA intervention among older adults. Methods: This secondary analysis of a prospective cohort study included 82 TIP-OA users who expressed interest in the program’s research component, met inclusion criteria, and provided informed consent. Participants completed both baseline and 8-week assessments or had 4-week data carried forward using the last observation carried forward (LOCF) method. The intervention consisted of weekly supportive phone calls over eight weeks. Baseline mental health risk level was assessed by clinicians during intake and categorized as low, medium, or high based on symptom severity within specific symptom categories. Associations between baseline risk level and changes in stress (primary outcome), depression, and anxiety (secondary outcomes) were examined. The primary outcome was measured by the Perceived Stress Scale (PSS; scores ranging from 0 (never) to 4 (very often)). Secondary outcomes were measured by the Patient Health Questionnaire-9 (PHQ-9; scores ranging from 0 (not at all) to 3 (nearly every day)), and the Generalized Anxiety Disorder-7 scale (GAD-7; scores can range from 0 (not at all sure) to 3 (nearly every day)). Results: At 8 -week follow-up assessment, participants with higher baseline risk levels showed greater reductions in stress (mean difference in Perceived Stress Scale reduction by 2.13, (F(1,77) = 2.82},

abstract = {Background/Objectives: Acute stress is known to influence food-related motivation and decision-making, often promoting a preference for energy-dense, palatable foods. However, traditional laboratory paradigms have limited ecological validity. This study examined the relationship between stress-induced physiological changes, eating behavior traits, and food cravings using a virtual reality (VR) adaptation of the Trier Social Stress Test (VR-TSST) followed by a VR supermarket task in adolescents. Methods: Thirty-eight adolescents (mean age 15.8 ± 0.6 years) participated in the study. Physiological parameters (HR, QT, PQ intervals) were recorded pre- and post-stress using a portable ECG device (WIWE). Perceived stress and eating behavior traits were evaluated with the Perceived Stress Scale (PSS) and the Three-Factor Eating Questionnaire (TFEQ-R21C), respectively. Immediately after the VR-TSST, participants performed a VR supermarket task in which they rated cravings for sweet, fatty, and healthy foods using visual analog scales (VAS). Paired-samples t-tests examined pre–post changes in physiological parameters, partial correlations explored associations between ECG responses and eating traits, and a 2 × 3 mixed-model Repeated Measures ANOVA assessed the effects of food type (sweet, fatty, healthy) and uncontrolled eating (UE) group (low vs. high) on post-stress cravings. Results: Acute stress induced significant increases in HR and QTc intervals (p < 0.01), confirming a robust physiological stress response. The ANOVA revealed a strong main effect of food type (F(1.93, 435.41) = 168.98, p < 0.001, η2p = 0.43), indicating that stress-induced cravings differed across food categories, with sweet foods rated highest. A significant food type × UE group interaction (F(1.93, 435.41) = 16.49, p < 0.001, η2p = 0.07) showed that adolescents with high UE exhibited greater cravings for sweet and fatty foods than those with low UE. Overall, craving levels did not differ significantly between groups. Conclusions: The findings demonstrate that acute stress selectively enhances cravings for high-reward foods, and that this effect is modulated by baseline uncontrolled eating tendencies. The combined use of VR-based stress induction and VR supermarket simulation offers an innovative, ecologically valid framework for studying stress-related eating behavior in adolescents, with potential implications for personalized nutrition and the prevention of stress-induced overeating. © 2025 by the authors.},
