Kiiroja L, Stewart SH, Gadbois S. Can scent-detection dogs detect the stress associated with trauma cue exposure in people with trauma histories? A proof-of-concept study. FRONTIERS IN ALLERGY 2024; 5:1352840. [PMID: 38606088 PMCID: PMC11006987 DOI: 10.3389/falgy.2024.1352840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Accepted: 02/02/2024] [Indexed: 04/13/2024] Open
Abstract
Introduction Post-traumatic stress disorder (PTSD) is an impairing mental health condition with high prevalence among military and general populations alike. PTSD service dogs are a complementary and alternative intervention needing scientific validation. We investigated whether dogs can detect putative stress-related volatile organic compounds (VOCs) in the breath of people with trauma histories (54% with PTSD) exposed to personalized trauma cues. Methods Breath samples were collected from 26 humans over 40 experimental sessions during a calm (control breath sample) and stressed state induced by trauma cue exposure (target breath sample). Two scent detection canines were presented with the samples in a two alternative forced choice (2AFC) discrimination and yes/no detection task. The 2AFC task assessed the dogs' ability to discriminate between the two states within the breath samples of one individual. The detection task determined their ability to generalize the target odour across different individuals and different stressful events of one individual. Signal Detection Theory was applied to assess dogs' sensitivity, specificity, precision, and response bias. Results The dogs performed at ∼90% accuracy across all sample sets in the discrimination experiment, and at 74% and 81% accuracy, respectively, in the detection experiment. Further analysis of dog olfactory performance in relation to human donor self-reported emotional responses to trauma cue exposure suggested the dogs may have been detecting distinct endocrine stress markers. One dog's performance correlated with the human donors' self-reported fear responses and the other dog's performance correlated with the human donors' self-reported shame responses. Based on these correlations between dog performance and donor self-report measures, we speculate that the VOCs each dog was detecting likely originated from the sympathetico-adreno-medullary axis (SAM; adrenaline, noradrenaline) in the case of the first dog and the hypothalamo-pituitary-adrenal axis (HPA; glucocorticoids) in the case of the second dog. Conclusion Our proof-of-concept study is the first to demonstrate that some dogs can detect putative VOCs emitted by people with trauma histories when experiencing distress theoretically associated with the intrusion and arousal/reactivity symptoms of PTSD. Results have potential to improve the effectiveness and training protocol of PTSD service dogs with a focus on enhancing their alert function.

Abstract
BACKGROUND Despite the myriad motor and non-motor challenges associated with Parkinson's disease (PD) diagnosis, the hidden issue of stigma may be among the most influential factors negatively affecting quality of life. A number of qualitative studies have been published assessing various aspects of stigma in PD, and quantitative studies assert that most people with PD experience stigma during the course of their disease. Stigma is associated with poorer mental and physical health, poorer quality of life, decreased levels of hope, self-esteem and self-efficacy. The resulting stigma can lead to social anxiety and isolation, reluctance to seek medical care, loneliness, depression and anxiety. Therefore, understanding what stigma is, where it comes from, and how it affects people living with PD may offer clinicians and care partners tools to help mitigate the negative effects. FOCUS Over the past few decades, we have seen a move away from simply focusing on the effects of a disease (medical model) toward a holistic biopsychosocial approach that considers the role of environmental factors (stigma) when assessing overall well-being. We review some proactive practical suggestions to help people living with PD effectively combat the negative effects of stigma. CONCLUSION The additional hidden burden of stigma from PD affects quality of life. Having a better understanding of the role of stigma and its impact may allow clinicians to provide proactive care and greater empathy for those living with the challenges of this disease.

Abstract
Both shame and guilt are self-conscious negative emotions claiming self-representations and self-awareness. Growing evidence indicates that these pessimistic emotions are associated to stress and stress-related disorders. The aim of this study was to translate and investigate the validity and reliability of the State Shame and Guilt Scale (SSGS) in a Greek adult population sample. A total of 181 adults (63% women) participated in the study. To validate the SSGS, correlations with the Depression Anxiety Stress Scales (DASS) and the Perceived Stress Scale (PSS) were also examined. Exploratory factor analysis was used to examine the factors of the Greek version of the SSGS. In addition, for greater validity, comparisons were made according to sex, marital status and level of education. The reliability assessment revealed that the index of internal consistency (Cronbach's alpha) was above the acceptable margin (0.7) for the three subscales (shame; 0.717, guilt; 0.770, pride; 0.874). The Greek version of the 15-item State Shame and Guilt Scale (SSGS) demonstrated good psychometric properties and could be proven useful for the assessment of shame, guilt, and pride.

CHILD ABUSE & NEGLECT 2022; 131:105744. [PMID: 35749903 DOI: 10.1016/j.chiabu.2022.105744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 06/09/2022] [Accepted: 06/13/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND High betrayal trauma (HBT), or interpersonal trauma perpetrated by someone close, is linked to dissociation and shame, while trauma perpetrated by someone less close, low betrayal trauma (LBT) is associated with post-traumatic stress disorder (PTSD). OBJECTIVE Child interpersonal trauma is common among women with chronic pelvic pain (CPP) and can negatively impact physical and mental health-related quality of life (HRQOL). Our study investigates unexplored connections between these variables. PARTICIPANTS & SETTING Survey data were analyzed from 96 English-speaking female patients with CPP at a women's health clinic (mean age = 33, 59 % White non-Hispanic, 62 % married or cohabitating, 61.5 % completed post-high school degree); prevalence of HBT and LBT were 65.2 % and 45.6 %, respectively. METHODS Multiple regression analyzed relationships between mental and physical HRQOL and dissociation, shame, and PTSD. Parallel mediation analyses examined indirect relationships between mental and physical HRQOL and exposure to childhood HBT and LBT. RESULTS Dissociation was related to worse physical HRQOL, while shame was related to worse physical and mental HRQOL. Dissociation and shame mediated relationships between childhood HBT and current mental (R2 = 0.08, p = .01) and physical (R2 = 0.11, p = .002) HRQOL. Shame, but not PTSD, mediated relationships between childhood LBT and current mental (R2 = 0.14, p < .001) and physical (R2 = 0.16, p < .001) HRQOL. CONCLUSIONS Our study provides preliminary evidence that dissociation and shame negatively impact HRQOL among individuals with CPP in the context of exposure to different types of childhood betrayal trauma. Replication studies to validate our results with larger samples and longitudinal designs are encouraged.

Abstract
OBJECTIVE The traditional Trier Social Stress Test (TSST) is a widely used standardized stress induction protocol and has recently been adapted in a variety of virtual reality environments (V-TSST). Research has demonstrated the ability of the V-TSST to induce a stress reactivity response measured via cortisol, heart rate, and self-report. However, research comparing stress reactivity induced via the V-TSST to the traditional TSST across neuroendocrine, cardiovascular, and self-report variables has not yet been systematically and quantitatively reviewed. METHODS In this meta-analytic review, the existing studies that used V-TSST were gathered, and each was age and sex matched with samples using the traditional TSST. These studies were then meta-analytically synthesized to determine if there was a moderating effect of TSST type (traditional TSST or V-TSST) on multiple measures of stress reactivity (i.e., cortisol, heart rate, and self-report). RESULTS Examining the pre-post stress induction, the V-TSST studies demonstrated comparable effect sizes (ESs) for stress reactivity (cortisol ES = 0.61, heart rate ES = 0.98, self-reported stress ES = 0.94) to traditional TSST study ESs (cortisol ES = 0.79, heart rate ES = 0.85, self-reported stress ES = 0.85). CONCLUSIONS The TSST type differences between ESs were not statistically significant, indicating that the V-TSST is as effective as the traditional TSST at eliciting a physiological and self-reported stress reactivity response. Implications and limitations of this meta-analysis are discussed, and recommendations for future research are provided.

Abstract
Burnout is common in many countries and is associated with several other problems such as depression, anxiety, insomnia, and memory deficits, and prospectively it predicts long-term sick-leave, cardiovascular disease, and death. Clinical burnout or its residual symptoms often last several years and a common assumption is that recovery takes a long time by nature, despite full time sick-leave and the absence of work stress. The literature suggests models that hypothetically explain the development, but not maintenance, of the syndrome. Based on cognitive and behavioral principles, stress research, and stress theories, this paper describes a theoretical model explaining how clinical burnout can develop and be maintained. While the development of clinical burnout is mainly explained by prolonged stress reactions and disturbed recovery processes due to work related stressors, maintenance of the syndrome is particularly explained by prolonged stress reactions and disturbed recovery processes due to the new context of experiencing burnout and being on sick-leave. Worry about acquired memory deficits, passivity and excessive sleep, shame, fear of stress reactions, and the perception of not being safe are examples of responses that can contribute to the maintenance. The model has important implications for research and how to intervene in clinical burnout. For example, it can offer support to professional care providers and patients in terms of focusing on, identifying, and changing current contextual factors and behaviors that maintain the individual’s clinical burnout symptoms and by that facilitate burnout recovery. Regarding research, the model provides a highly important reason for researchers to study contextual factors and behaviors that contribute to the maintenance of clinical burnout, which has been neglected in research.

Abstract
We examined the predictive relations of social media and smartphone use to body esteem in female adolescents and the mechanism that underlies these relations. As a result of frequent social media and smartphone use, adolescents are continually exposed to appearance-related media content. This likely reinforces a thin ideal and fosters appearance-based comparison and increases fear of external evaluation. Hence, we investigated a cognitive-affective framework in which the associations of social media and smartphone use with body esteem are serially mediated by cognitive internalization of an ideal body image, appearance comparisons, and social appearance anxiety. By testing female adolescents (N = 100) aged 13 to 18, we found that excessive social media use leads to unhealthy body esteem via intensified cognitive internalization, which aggravates appearance comparisons and anxiety regarding negative appearance evaluation. Further, we found that screen time for specific smartphone activities also harmed body esteem, independent of social media use. However, overall smartphone screen time did not affect body esteem when social media use was taken into consideration. Our findings underscore the multifactor mechanism that elucidates the negative impacts of social media and smartphone activities on body esteem in female adolescents, who are developmentally susceptible to poor body esteem.

Abstract
Dementia is highly prevalent among the worldwide elderly population. Only a small number of the currently marketed drugs are effective in controlling its symptoms, and none has any effect on its progression. Further, as the condition advances, even these pharmaceuticals lose their efficiency, and new research into interventions that might improve the life quality of patients at the end stage of dementia and their families is increasingly rare. In our previous studies, we explored the benefits of exposure to nature, in the form of a Japanese garden, for persons with advanced dementia. In the current work, we extended our observations to two new locations and a new set of subjects with a different ethnic composition with the goal of identifying interventions that might improve their quality of life. We found that, even in these new settings, garden observation not only relieved physiological stress, it improved qualitative measures such as verbalization and memory retrieval. We present data that viewing the garden is a holistic experience rather a solely visual stimulus. Our new data further support the conclusion that garden observation is worth including in the care planning schedule of advanced dementia patients. Its low cost and easy availability make it an economical adjunct to current pharmacological methods that has the potential to improve the quality of life of people with dementia.

Abstract
Social self-preservation theory posits that stress is experienced when an aspect of an individual's identity has the potential to be negatively evaluated. Appearance is a central part of identity; however, little research has examined whether perceived appearance judgements are a source of social-evaluative stress. In addition, stress may be an explanatory link in the association between appearance perceptions and depressive symptoms. This study examined whether perceived appearance judgements were associated with increased stress and greater depressive symptoms among adults. Study 1 examined the associations between self-reported appearance judgements and cortisol stress responses in response to a laboratory stressor (Trier Social Stress Test) among 71 individuals aged 18-65. Study 2 assessed self-reported appearance judgements and depressive symptoms among 498 adults ages 18-65 via an online survey data collection. Appearance judgement was associated with a stronger cortisol response, higher self-reported stress, and greater depressive symptoms. Stress mediated all associations between appearance judgements and depressive symptoms and neither age nor gender moderated these associations. The findings suggest that appearance judgements contribute to psychological and biological stress processes and demonstrated that stress mediated the association between appearance judgements and depressive symptoms.

Abstract
IMPORTANCE Anorexia nervosa (AN) is associated with adolescent onset, severe low body weight, and high mortality as well as high harm avoidance. The brain reward system could have an important role in the perplexing drive for thinness and food avoidance in AN. OBJECTIVE To test whether brain reward learning response to taste in adolescent AN is altered and associated with treatment response, striatal-hypothalamic connectivity, and elevated harm avoidance. DESIGN, SETTING, AND PARTICIPANTS In this cross-sectional multimodal brain imaging study, adolescents and young adults with AN were matched with healthy controls at a university brain imaging facility and eating disorder treatment program. During a sucrose taste classical conditioning paradigm, violations of learned associations between conditioned visual and unconditioned taste stimuli evoked the dopamine-related prediction error (PE). Dynamic effective connectivity during sweet taste receipt was studied to investigate hierarchical brain activation across the brain network that regulates eating. The study was conducted from July 2012 to May 2017, and data were analyzed from June 2017 to December 2017. MAIN OUTCOMES AND MEASURES Prediction error brain reward response across the insula, caudate, and orbitofrontal cortex; dynamic effective connectivity between hypothalamus and ventral striatum; and treatment weight gain, harm avoidance scores, and salivary cortisol levels and their correlations with PE brain response. RESULTS Of 56 female participants with AN included in the study, the mean (SD) age was 16.6 (2.5) years, and the mean (SD) body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) was 15.9 (0.9); of 52 matched female controls, the mean (SD) age was 16.0 (2.8) years, and the mean (SD) BMI was 20.9 (2.1). Prediction error response was elevated in participants with AN in the caudate head, nucleus accumbens, and insula (multivariate analysis of covariance: Wilks λ, 0.707; P = .02; partial η2 = 0.296), which correlated negatively with sucrose taste pleasantness. Bilateral AN orbitofrontal gyrus rectus PE response was positively correlated with harm avoidance (right ρ, 0.317; 95% CI, 0.091 to 0.539; P < .02; left ρ, 0.336; 95% CI, 0.112 to 0.550; P < .01) but negatively correlated with treatment BMI change (right ρ, -0.282; 95% CI, -0.534 to -0.014; P < .04; left ρ, -0.268; 95% CI, -0.509 to -0.018; P < .045). Participants with AN showed effective connectivity from ventral striatum to hypothalamus, and connectivity strength was positively correlated with insula and orbitofrontal PE response. Right frontal cortex PE response was associated with cortisol, which correlated with body dissatisfaction. CONCLUSIONS AND RELEVANCE These results further support elevated PE signal in AN and suggest a link between PE and elevated harm avoidance, brain connectivity, and weight gain in AN. Prediction error may have a central role in adolescent AN in driving anxiety and ventral striatal-hypothalamus circuit-controlled food avoidance.

Abstract
The primary goal of this study was to examine the associations between baseline body image dissatisfaction (BID) and subsequent anxiety trajectories in a diverse, community sample of adolescent girls and boys. Participants were 581 adolescents (baseline age: M = 16.1, SD = 0.7; 58% female; 65% non-Hispanic White) from U.S. public high schools. Self-report questionnaires were administered during school at 3 annual assessment waves. Latent growth curve modeling examined the association between baseline BID and growth factors of anxiety disorder symptom trajectories. Covariates included baseline gender, age, race/ethnicity, parental education attainment, body mass index standard scores, and depressive symptoms. Higher BID at baseline was significantly associated with higher initial symptoms of generalized anxiety disorder (GAD), panic disorder (PD), social anxiety disorder (SAD), and significant school avoidance (SSA; ps = .001-.04) but was unrelated to initial separation anxiety disorder (SEP) symptoms (p = .27). Higher baseline BID also was associated with attenuated decreases in SAD symptoms across time (p = .001). Among adolescents with low baseline anxiety symptoms only, higher BID was associated with more attenuated decreases in SAD symptoms (p = .01) and greater increases in PD symptoms (p = .02). BID was unrelated to changes in GAD, SEP, and SSA symptoms (ps = .11-.94). Findings suggest that BID is associated with concurrent symptoms of multiple anxiety disorders and may have a prospective link to SAD and PD symptoms during adolescence. As such, assessing body image issues may be important to assess when identifying adolescents at risk for exacerbated SAD and PD symptoms.

Abstract
Framed within social self-preservation theory, the present study investigated men's psychobiological responses to social-evaluative body image threats. University men ( n = 66) were randomly assigned to either a high or low social-evaluative body image threat condition. Participants provided saliva samples (to assess cortisol) and completed measures of state body shame prior to and following their condition, during which anthropometric and strength measures were assessed. Baseline corrected values indicated men in the high social-evaluative body image threat condition had higher body shame and cortisol than men in the low social-evaluative body image threat condition. These findings suggest that social evaluation in the context of situations that threaten body image leads to potentially negative psychobiological responses in college men.
