The study aimed to investigate the persistence or changes in trait resilience of parents over a 6-year period and its association with stressful life events (SLEs). Furthermore, we explored the potential protective effect of trait resilience against exposure to stressful life events and their negative mental health consequences. The study population was drawn from the ongoing FinnBrain Birth Cohort Study and included 1388 mothers and 657 fathers who completed the CD-RISC-10 questionnaire during pregnancy and again 6 years later. Data collection involved self-report questionnaires, including CD-RISC-10, EPDS, SCL-90, and a questionnaire on SLEs. Data analysis utilised linear regression and statistical assessments. Parents in the highest or lowest quartile of resilience showed greater stability in resilience scores over time compared to those in the middle quartiles. Trait resilience during pregnancy was significantly associated with resilience 6 years later. SLEs did not moderate this association. Additionally, higher trait resilience consistently associated with lower levels of distress symptoms. The investigation of SLEs may require more nuance due to their event-specific variability of impact. Furthermore, the study's sample size of individuals who experienced a high frequency of stressful life events was limited. Trait resilience appears to be rather stable, but also susceptible to some change. Because of its persistency and the positive impact on mental health it is worthwhile to be assessed as a part of comprehensive evaluation of parents' mental health.

Stress-sensitivity (SS) is considered a psychobiological trait possibly resulting from the interaction of genetic and environmental factors (GxE). This study examined whether the interaction of SS-related genetic markers with interview-based dimensions of childhood adversity predicted longitudinal trajectories of low versus high SS. Participants were nonclinically-ascertained young adults comprising normative and elevated scores on schizotypy. SS trajectories were defined in a previous report based on three prospective assessments (23.5, 25, 28 years-old) of both retrospective (Perceived Stress Scale; PSS) and momentary (Experience Sampling Methodology; ESM) stress ratings. A total of n = 177 and n = 165 participants with PSS and ESM stress-sensitivity trajectories, respectively, as well as genetic data, were included in the study. GxE effects between a SS Polygenic Risk Score (PRS-SS) and a Genetic Risk Score of the Hypothalamic Pituitary Adrenal axis (GRS-HPA) with childhood adversity dimensions (Intrafamilial Adversity, Threat and Deprivation) on SS trajectories were examined. Threat was the most consistent predictor of persistently high SS. PRS-SS moderated the association of Threat with high-PSS. GRS-HPA moderated the effects of all adversity dimensions on high-PSS. The interaction of PRS-SS with Deprivation and GRS-HPA with Intrafamilial Adversity predicted trajectories of momentary social stress, but the effects were driven by those with lower genetic susceptibility. Genetic-HPA-axis moderates the effects of all adversity dimensions on persistent SS trajectories, as well as PRS-SS and Threat, particularly for retrospective stress measure. The findings highlight the complex interplay between GxE factors and suggest that PSS may better capture SS trait. Including biologically-meaningful GRS indexing SS and adversity dimensions in future studies using comprehensive stress measures would enhance our knowledge on high SS susceptibility and its relationship with diverse psychopathological outcomes.

This study explores the relationship between perceived discrimination and social adaptation of migrant workers' children, as well as the mediating role of sense of alienation and the moderating role of psychological capital. A multi-stage-multi-source longitudinal study design was adopted. A total of 423 Chinese migrant workers' children (M_age = 13.36, Female ratio = 39.48%) were recruited, and sample data were collected at three time points for 6 months. The results indicated that the interpersonal alienation played a mediating role between discriminatory perception and social adaptation. Psychological capital moderated the relationship between perceived discrimination and interpersonal alienation. Compared to participants with high psychological capital, interpersonal alienation played a stronger mediating role between perceived discrimination and social adaptation among those with low psychological capital. Perceived discrimination could reduce the level of social adaptation of migrant workers' children through interpersonal alienation. The social adaptation of migrant workers' children could be improved by improving the level of psychological capital.

The associations of suicidality with stress are poorly studied in schizophrenia. The study aimed to determine whether suicidality was correlated with perceived chronic stress and the cortisol fluctuations under stress tasks in schizophrenia. High suicidality was defined as a lifetime history of suicide attempts or suicidal ideation in the past 2 weeks. Individuals with schizophrenia and high suicidality (SZ-HS, n = 59), with low suicidality (SZ-LS, n = 207), and healthy controls (HC, n = 196) finished the Perceived Stress Scale. Then, they participated in an experiment that induced stress using the Paced Auditory Serial Addition Task and the Mirror Tracing Persistence Task. Negative affect was measured at baseline and after finishing each task. The salivary cortisol was collected before-, after 20 min, and after 40 min of the tasks. SZ-HS had elevated perceived stress than SZ-LS and HC. Mixed effect models showed that stress tasks induced cortisol changes in all groups; cortisol of SZ-LS was reduced more than HC, but SZ-HS and SZ-LS did not differ in cortisol fluctuations. SZ-HS and SZ-LS experienced similar negative affect changes during tasks and the difference in withdrawal rates was nonsignificant. SZ-HS had an increased error rate than SZ-LS. In conclusion, suicidality was correlated with high-level perceived stress but did not result in differences in cortisol reactivities under stress tasks. It suggests the inconsistency between appraisal of stress and biological stress system disturbance among SZ-HS compared to SZ-LS.

Deployment to active conflict zones significantly affects military families, with spouses often experiencing heightened stress and mental health challenges. However, research on non-US military spouses, particularly those of reserve soldiers, who may face unique stressors compared to active-duty personnel, remains scarce. This study examined perceived stress profiles among Israeli spouses of reserve soldiers during the ongoing Israel-Hamas War, and their associations with deployment stressors, mental health outcomes, and psychological protective factors. A volunteer sample of Israeli spouses of reserve soldiers (n = 293) responded to self-report questionnaires in a cross-sectional study. Using latent profile analysis of the ratings of perceived stress, three distinct profiles were identified: low (35.1%), moderate (43.5%), and high (21.3%). Higher levels of deployment stressors (e.g., fear of spouse getting physically injured) predicted membership in the moderate and high-stress profiles, while better household management was associated with lower stress profiles. The high-stress profile reported significantly greater symptoms of depression and anxiety compared to the low and moderate stress profiles. In contrast, the low-stress profile exhibited higher levels of resilience, self-compassion, and perceived social support. These findings highlight the variability in spouses' stress responses during wartime deployment and identify key factors associated with psychological adjustment. Results suggest that deployment-related fears, household management abilities, and psychological resources are crucial in shaping stress profiles and mental health outcomes among military spouses.

Military personnel are often exposed to high levels of both physical and psychological challenges in their work environment and therefore it is important to be trained on how to handle stressful situations. The primary aim of this study was to examine whether military-specific virtual battle space (VBS) scenarios could elicit a physiological and subjective stress response in healthy military personnel, as compared to that of a virtual reality height exposure (VR-HE) stress task that has shown to reliably increase stress levels. Twenty participants engaged in two VBS scenarios and the VR-HE during separate sessions, while measurements of heart rate (HR), heart rate variability (HRV), respiration rate, and subjective stress levels were collected. Contrary to our initial expectations, analysis revealed that neither of the VBS scenarios induced a significant stress response, as indicated by stable HR, HRV, and low subjective stress levels. However, the VR-HE task did elicit a significant physiological stress response, evidenced by increased HR and HRV changes, aligning with previous research findings. Moreover, no discernible alterations were detected in cognitive performance subsequent to these stressors. These results suggest that the current VBS scenarios, despite their potential, may not be effective for stress-related training activities within military settings. The absence of a significant stress response in the VBS conditions points to the need for more immersive and engaging scenarios. By integrating interactive and demanding elements, as well as physical feedback systems and real-time communication, VBS training might better mimic real-world stressors and improve stress resilience in military personnel. The findings of this study have broader implications for stress research and training, suggesting the need for scenario design improvements in virtual training environments to effectively induce stress and improve stress management across various high-stress professions.

Perseverative thinking and catastrophizing have well established associations with fear and distress. However, less is known about the impact of interpersonal dynamics, such as co-rumination, on these intrapersonal cognitive processes and subsequent stress. The present study addresses this knowledge gap. A sample of 433 adults from across the United States was recruited online and completed measures of co-rumination, perseverative thinking, catastrophizing, and demographic characteristics early in the COVID-19 pandemic, and the COVID Stress Scales (CSS) at six month follow up. Co-rumination, perseverative thinking, catastrophizing, and CSS scores were correlated in the expected direction. Regression analyses revealed all three independently predicted CSS worry about the dangerousness of COVID-19 subscale. Co-rumination was the strongest predictor of CSS worry about the socioeconomic impact and CSS compulsive checking scales. Perseverative thinking and catastrophizing predicted CSS traumatic stress symptoms subscale. Finally, perseverative thinking was the strongest predictor of CSS xenophobia subscale. Structural equation modelling indicated that co-rumination had a significant indirect effect on CSS scores through perseverative thinking and catastrophizing. Interpersonal dynamics, such as co-rumination, are relevant for understanding stress and are promising targets for intervention research to prevent or attenuate fears and distress, in addition to traditional intrapersonal cognitive processes such as perseverative thinking and catastrophizing.

As the largest minoritised ethnic group in the United States, Latinxs face a greater risk for type 2 diabetes and depression. The aim of the present study was to explore whether the relationship between depressive symptoms and insulin resistance among Latinxs with type 2 diabetes was moderated by toxic stressors arising from urban environmental threat (i.e., uncomfortable or unsafe aspects of city life). A community sample of Latinx adults with type 2 diabetes (n = 121) was recruited from Hartford, Connecticut. Participants self-reported depressive symptoms and exposure to urban environmental threat using items from the Patient Health Questionnaire and Urban Hassles Index, respectively. Insulin and glucose levels assessed via fasting blood draw were used to calculate insulin resistance using the HOMA-IR formula. After controlling for demographic, financial and health-related factors, results from a regression analysis revealed a significant interaction between depressive symptoms and urban environmental threat; more severe symptoms of depression predicted greater insulin resistance, but only amongst those with frequent exposure to urban environmental threats. Findings from the current study suggest that improving urban living conditions may offer an alternate avenue for attenuating the deleterious impacts of depression on type 2 diabetes progression in Latinxs.

Compared to research about the effects of work-related interpersonal experiences on employee behaviours at home, research on whether and how home-related interpersonal experiences can affect employee behaviours at work has received less attention. This study aimed to contribute to this literature by examining whether interpersonal conflict at home can predict employee silence through exhaustion at work. The moderating effect of affective commitment on the relationship between interpersonal conflict at home and exhaustion was also explored. Using a two-wave design with data from 246 full-time employees, the current study found that interpersonal conflict at home positively predicted employee silence through exhaustion at work. Further, affective commitment exacerbated the relationship between interpersonal conflict at home and exhaustion at work. Our findings extend the understanding of mediating and moderating mechanisms for the effect of negative experiences at home on work behaviours.

Psoriasis exhibits a higher incidence of anxiety and depression. However, the diagnostic process heavily relies on subjective evaluation. Fatty acid-binding protein 7 (FABP7) and serotonin (5-HT) are considered as potential plasma biomarkers. We aimed to investigate the potentiality of plasma FABP7 and 5-HT as biomarkers for predicting anxiety and depression in psoriasis. Data were analysed from 140 patients with psoriasis in the Shanghai Psoriasis Effectiveness Evaluation CoHort (SPEECH). Unsupervised clustering was employed to group patients based on their FABP7 and 5-HT profiles. Subsequently, patients were categorised into Group 1 (lower FABP7 and higher 5-HT) or Group 2. Multivariate logistic regression was employed to investigate the correlation between the FABP7-5-HT pattern and anxiety or depression in psoriasis patients. Patients with psoriasis have a higher incidence of anxiety or depression, as well as higher levels of FABP7 and lower levels of 5-HT. After clustering patients using K-means clustering, Group 2 showed a higher body mass index, a higher incidence of hypertension, more severe psoriasis, and more significant anxiety and depression compared to Group 1. Multivariate logistic regression shows that adjusting for covariates except PASI, duration of psoriasis, and psoriatic arthritis, Group 2 had a higher risk of anxiety and depression compared to Group 1. Further adjustment for covariates yielded similar results. Pattern of FABP7-5-HT that may indicate an association with psoriasis accompanied by anxiety or depression.
