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.},

abstract = {Purpose: To investigate the coping strategies of youth sexual offenders, which are believed to be important elements in the development of sexual offending behaviours. Subjects and method: This cross-sectional study investigated two groups of male adolescents (n = 196) consisting of youth sexual offenders and non-offender peers. Examination of the coping strategies was measured by a Coping Inventory for Stressful Situations (CISS). Results: It was hypothesized that youth sexual offenders used sex-related activities and emotions as coping strategies to alleviate negative emotional states and problematic situations. The results obtained demonstrated that youth sexual offenders make less use of sex-related activities as a way of coping with stressful situations, but make more use of emotions-coping strategies when compared to non-offender peers. An attempt was made to predict youth as sexual offenders or non-offenders according to the coping strategies they used in times of stress. The logistic regression model used was statistically significant and the analysis performed increased the likelihood of correctly identifying youth sexual offenders based on the coping strategies used in times of stress. Conclusion: The results of the study demonstrated that youth sexual offenders have a tendency to use emotional responses to cope with life's difficulties, which may be increasing their level of stress and thereby placing them at a higher risk to offend sexually. © 2009 Elsevier Masson SAS.
