This study examined the effects of acute operational and passive heat stress on cognitive performance in a randomized controlled trial with 68 service members. Participants were assigned to either a low- or high-stress group and completed two military scenarios using a desktop simulator. Passive heat stress was applied only to the high-stress group in a portable environmental facility. Decision-making and situational awareness were scored from scenario recordings, while executive functioning was assessed through a cognitive test battery. In addition to the group comparison, a heat index capturing individual variability in thermal strain was calculated. Contrary to expectations, heat stress did not impair cognitive performance across most domains. Decision-making performance actually improved over time in the high-stress group, with significantly better performance during the second assessment compared to the low-stress group. Cognitive flexibility also improved significantly within both groups. These changes are attributed primarily to learning effects rather than stress-induced performance. Situational awareness showed no significant differences between groups. Exploratory heat index analyses revealed that participants in the high heat index group exhibited increased situational awareness over time, suggesting a possible inverted U-shaped relationship between thermal strain and performance. In contrast, inhibition improved only in the low heat index group. Together, these findings emphasize that the heat stress protocol may not have been potent enough to generate the cortisol response needed to detrimentally affect higher-order cognition. Nevertheless, the findings highlight that thermal strain can interact with cognitive performance in complex, nonlinear ways. While passive heat stress remains a promising stressor for research, its effect may only become fully apparent under more intense or physiologically demanding conditions, warranting further investigation into its potential impact on higher-order cognitive functions in military contexts.</p>","PeriodicalId":52315,"journal":{"name":"Chronic Stress","volume":"10 ","pages":"24705470261416768"},"PeriodicalIF":0.0,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12864672/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146121111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With mental health concerns rising in the Philippines, help-seeking behaviors are crucial in addressing issues like emotional distress, and suicidal ideation. A sample of 440 college students aged 18-30 from Metro Manila were surveyed to determine whether self-efficacy affects the likelihood of seeking help for personal/emotional problems and suicidal ideation. Three validated instruments- the McCroskey Shyness Scale, the General Help-Seeking Questionnaire, and the General Self-Efficacy Scale- were used through an online survey. The results indicated that self-efficacy was found to be an indirect pathway linking shyness and help-seeking behavior for suicidal ideation but did not have the same effect for personal/emotional problems. Also, shyness alone did not significantly predict help-seeking behavior for either problem. Furthermore, moderated mediation analyses showed that these pathways did not significantly differ by sex, although conditional effects suggested that mediating role of self-efficacy may be more pronounced among females.

Post-traumatic stress disorder (PTSD) is a type of psychological stress that occurs in critical situations that pose a direct threat to the life of the person and/or his or her loved ones. The prevalence of PTSD is increasing every year due to growing exposure to traumatic factors such as wars, natural disasters, and other crises. These events lead to severe psychological consequences, affecting a rising number of people worldwide. Currently, PTSD can be challenging to treat due to the complex nature of the disorder, variability in individual responses to treatment, and limitations in available therapeutic options. Considering the emergency need for effective PTSD treatment, a drug repurposing strategy presents a promising avenue to accelerate the availability of therapies. Here, we summarized and described drugs that were repurposed for alleviating PTSD symptoms. Moreover, we discussed the potential of some drugs, including alpha-adrenergic modulators, cannabinoids, glutamatergic modulators, and antipsychotics, for being repurposed for PTSD treatment. Drug repurposing implies the rapid identification of compounds with an established safety profile and known therapeutic effects that may be effective in PTSD.

{"title":"Do People Seeking Care for Musculoskeletal Symptoms Experience Greater Agency and Better Experience Based on Written Information About Their Illness?","authors":"Emily H Jaarsma, Ali Azarpey, Drew Aronoff, David Ring, Amin Razi","doi":"10.1177/24705470251382668","DOIUrl":"10.1177/24705470251382668","url":null,"abstract":"<p><strong>Objectives: </strong>Current patient-facing health information may unintentionally reinforce unhelpful and less adaptive mindsets regarding musculoskeletal symptoms. This prospective randomized trial evaluated the impact of psychologically-informed educational material, explicitly designed to promote healthier interpretations of bodily sensations according to cognitive science principles, on patient experience when compared to standard professional society materials.</p><p><strong>Methods: </strong>In this trial, 133 adults presenting to an upper extremity specialist with one of eight common non-traumatic musculoskeletal conditions were randomly assigned to review health information produced by either: 1) a professional musculoskeletal society or 2) revised material created by the authors and psychologist collaborators. Participants completed surveys containing validated measures assessing personal health agency (PAM-13), perceived clinician empathy (JSPPPE) and emotional response to the material.</p><p><strong>Results: </strong>There were no significant differences based on the type of material reviewed. However, on multivariable analysis, participants diagnosed with rotator cuff tendinopathy, ganglion cyst, or carpal and cubital tunnel syndrome reported more negative emotional responses compared to those with lateral epicondylitis, regardless of the type of written material reviewed.</p><p><strong>Conclusions: </strong>Cognitively-informed musculoskeletal health information was acceptable to patients but did not yield measurable improvements in emotional response, agency, or perceived empathy when compared to standard material. During the visit, diagnosis-specific factors may influence patient reactions more than information framing.</p><p><strong>Practice implications: </strong>Patients find clear, accessible material designed to cultivate the healthiest possible interpretation of bodily sensations acceptable and non-distressing. Future interventions should explore diagnosis-specific tailoring of information or repeated exposure to impact outcomes.</p><p><strong>Level of evidence: </strong>II.</p>","PeriodicalId":52315,"journal":{"name":"Chronic Stress","volume":"9 ","pages":"24705470251382668"},"PeriodicalIF":0.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12461074/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
