Stress of soil moisture and temperature exacerbates the toxicity of tire wear particles to soil fauna: Tracking the role of additives through host microbiota.

Tire wear particles (TWPs) are considered as an emerging threat to soil fauna. However, how TWP toxicity to soil fauna responds to the stress of soil moisture and temperature remains unclear. We assessed the toxicity of environmentally relevant TWPs to the soil model species Enchytraeus crypticus under three soil moisture and two temperature gradients. Typical thermoplastic polypropylene (PP) was selected for comparison. Results showed that compared with PP, TWPs exerted stronger toxicity, including decreasing the worm growth, survival and reproduction rates, disturbing the soil and worm gut microbiota, and leaching more diverse and higher contents of additives. Stress of soil moisture and temperature exacerbated TWP toxicity mainly through affecting the leaching and transformation of additives. Fourteen mediated additives significantly contributed to the shift of the gut microbiota under soil moisture and temperature stress, among which 1,3-diphenylguanidine, N,N'-bis(methylphenyl)-1,4-benzenediamine quinone, N-tert-butyl-2-benzothiazolesulfenamide, and 2-aminobenzothiazole were identified as the main drivers. In addition, this study provided the first clear evidence that increased soil moisture and temperature promoted the transformation of additives in the soil. Our study revealed the non-negligible aggravated toxicity of TWPs to soil fauna under stress of soil moisture and temperature, providing novel insights into the environmental behavior of additives.

Differential effects of lifetime stressors on major depressive disorder severity: a longitudinal community-based cohort study.

BACKGROUND: Stressors across the lifespan are associated with the onset of major depressive disorder (MDD) and increased severity of depressive symptoms. However, it is unclear how lifetime stressors are related to specific MDD subtypes. The present study aims to examine the relationships between MDD subtypes and stressors experienced across the lifespan while considering potential confounders. METHODS: Data analyzed were from the Zone d'Épidémiologie Psychiatrique du Sud-Ouest de Montréal (N = 1351). Lifetime stressors included childhood maltreatment, child-parent bonding, and stressful life events. Person-centered analyses were used to identify the clusters/profiles of the studied variables and multinomial logistic regression analyses were performed to examine the relationships between stressors and identified MDD subtypes. Intersectional analysis was applied to further examine how distal stressors interact with proximal stressors to impact the development of MDD subtypes. RESULTS: There was a significant association between proximal stressors and melancholic depression, whereas severe atypical depression and moderate depression were only associated with some domains of stressful life events. Additionally, those with severe atypical depression and melancholic depression were more likely to be exposed to distal stressors such as childhood maltreatment. The combinations of distal and proximal stressors predicted a greater risk of all MDD subtypes except for moderate atypical depression. CONCLUSIONS: MDD was characterized into four subtypes based on depressive symptoms and severity. Different stressor profiles were linked with various MDD subtypes. More specific interventions and clinical management are called to provide precision treatment for MDD patients with unique stressor profiles and MDD subtypes.

COVID-19's Impact in Long-Term Care Facilities: The Health and Coping Strategies of Older Adults and Their Families.

AIM: Describe the stressors that long-term care facility (LTCF) residents and their family members were exposed to during the COVID-19 pandemic, the resources they mobilised to cope with them, and the strategies used by professionals to support them. DESIGN: A descriptive qualitative design study. METHOD: Between March 2021 and February 2022, we carried out semi-structured interviews with 8 LTCF residents, 11 family members, and 6 focus groups made up of healthcare and support staff from 8 LTCFs. RESULTS: Three themes emerged: (1) residents and family members: separated and suffering, (2) residents and family members: reinventing themselves, and (3) staff: attempts to maintain residents' well-being. CONCLUSION: LTCF Residents' and their family members' exposure to the various stressors linked to the COVID-19 pandemic generated suffering. Healthcare and support staff implemented strategies to support them, notably to maintain links between them. Some deep reflection must occur on the concepts of LTCF residents' autonomy and self-determination when implementing protective measures in future pandemic situations. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: This study has provided new insights into the nature of the stressors faced by LTCF residents and their families, and the measures implemented by professionals to support them. The role of the families of LTCF residents needs to be better recognised. Our results indicate the importance of involving nurses in discussions on patient autonomy and self-determination when implementing protective measures (in a pandemic situation). IMPACT: Exploring the nature of the stressors experienced by LTCF residents and their families enables professionals to tailor strategies to support them. Maintaining residents' self-determination is essential when implementing protective measures. Families involved with residents must be recognised and included in the assessment of stressors and the personalisation and implementation of strategies to support LTCF residents. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

Differential response of multiple stream ecosystem processes to basin- and reach-scale drivers.

Stream ecosystems are inherently dependent on their surroundings and, thus, highly vulnerable to anthropogenic impacts, which alter both their structure and functioning. Anchored in biologically-mediated processes, the response of stream ecosystem functioning to environmental conditions exhibits intricate patterns, reflecting both natural dynamics and human-induced changes. Our study aimed at determining the natural and anthropogenic drivers influencing multiple stream ecosystems processes (nutrient uptake, biomass accrual, decomposition, and ecosystem metabolism) at a regional scale. By examining 38 natural and anthropogenic variables across 63 stream reaches in Gipuzkoa (northern Iberian Peninsula), we used structural equation modeling to unravel the cascading effect of basin- and reach-scale drivers onto ecosystem process. The results reveal significant variability in ecosystem processes, with contrasting spatial patterns, suggesting that studied processes respond differently to environmental factors. Urban land-use emerged as a primary basin-scale driver, whereas reach-scale variables reflected both natural and anthropogenic influence. Nutrient uptake rates were primarily driven by nutrient concentrations in stream water, but models for biomass accrual, decomposition, and ecosystem metabolism exhibited more complex cause-effect relationships. Our findings highlight the impact of urban areas on multiple ecosystem processes and services, disproportionate when considering their small land cover. The present study emphasizes the convenience of measuring multiple ecosystem functions simultaneously to get a comprehensive diagnosis of the functional status of rivers.

Integrating social, climate and environmental changes to confront accelerating global aging.

INTRODUCTION: The global increase in the aging population presents critical challenges for healthcare systems, social security, and economic stability worldwide. Although the studies of the global rate of aging have increased more than four times in the past two decades, few studies have integrated the potential combined effects of socio-economic, climatic, and environmental factors. METHODS: We calculated the geographic heterogeneity of aging population growth rates from 218 countries between 1960 and 2022. Public databases were then integrated to assess the impacts of seven global stressors: socio-economic vulnerability, temperature, drought, seasonality, climate extremes, air pollution, and greening vulnerability on growth rates of aging population (a totally 156 countries). Linear regression models were primarily used to test the statistically significant effects of these stressors on the rate of aging, and multiple model inference was then used to test whether the number of stressors exceeding specific thresholds (e.g., > 25, 50, and 75%) was consistently significant in the best models. The importance of stressors and the number of stressors exceeding thresholds was verified using random forest models for countries experiencing different population aging rates. RESULTS: Our analysis identified significant heterogeneity in growth rates of aging population globally, with many African countries exhibiting significantly lower aging rates compared with Europe. High socio-economic vulnerability, increased climate risks (such as high temperature and intensive extreme climate), and decreased environmental quality were found to significantly increase growth rates of the aging population (P < 0.05). The positive combined impacts of these stressors were diminished at medium-high levels of stressors (i.e., relative to their maximum levels observed in nature). The number of global stressors exceeding the 25% threshold emerged as an important predictor of global aging rates. Demographic changes in regions with relatively rapid aging (e.g., Africa and Asia) are more sensitive to climate change (e.g., extreme climate and drought) and the number of global stressors, and regions with low to medium rates of aging (e.g., Europe and the Americas) are more sensitive to socio-economic vulnerability and environmental stability (e.g., drought, green fragility and air pollution). CONCLUSIONS: Our findings underscore that policy tools or methods must be developed that consider the holistic dimension of the global factor. Further investigations are essential to understand the complex interactions between multiple stressors and their combined effects on global aging.

Daily Effects of Challenge and Hindrance Stressors on Work-to-Family Spillover: The Moderating Effects of Engaging in Workaholic Behaviors.

This study seeks to investigate the effects of challenge and hindrance stressors, and the moderating role of workaholic behaviors in predicting work-to-family positive and negative spillover. Non-instructional personnel at a public university completed measures of stressors and workaholic behaviors during the workday and work-to-family spillover before going to bed over a period of five weekdays (Level-1 N = 386; Level-2 N = 106). Results from multilevel regression indicated that challenge stressors exhibited no relationship with work-to-family positive or negative spillover, while hindrance stressors were positively related to negative work-to-family spillover. Additionally, workday hindrance, but not challenge, stressors interacted with workaholic behaviors to predict nightly work-to-family positive and negative spillover. Our findings highlight the detrimental effects of hindrance stressors on days when employees engage in workaholic behaviors and offer insights regarding reducing such stressors in the workplace.

Examining Daily Self-Efficacy, Minority Stressors, and Alcohol and Other Drug Use Among Trauma-Exposed Sexual Minority Women and Transgender and Gender-Diverse People.

BACKGROUND AND PURPOSE: This study aimed to develop and test a novel model integrating social-learning and self-medication frameworks by examining the association between self-efficacy to resist alcohol and other drug (AOD) use and daily AOD use and unhealthy drinking risk among trauma-exposed sexual minority women (SMW) and transgender and gender-diverse (TGD) people. We examined whether minority stressors moderated these associations. METHODS: Data were from 57 trauma-exposed SMW and TGD people who participated in a 14-day daily diary study. Multilevel binary logistic models and ordinal logistic models were employed to examine associations between self-efficacy to resist AOD use and daily AOD use and unhealthy drinking risk at within- and between-person levels. We assessed same- and cross-level interactions between daily self-efficacy to resist AOD use and minority stressors in predicting AOD use and unhealthy drinking risk within the same 24-hour period (i.e., standardized as 6 pm to 6 pm; hereafter referred to as "same-day"). RESULTS: Self-efficacy to resist AOD use was associated with lower AOD use and unhealthy drinking risk. Minority stressors were associated with daily AOD use. Among those who experienced higher (vs. lower) average sexual minority stressors over the 2-week daily diary period, higher-than-usual self-efficacy to resist AOD use was less protective in decreasing risk of same-day unhealthy drinking. CONCLUSIONS: Interventions aiming to mitigate AOD use and unhealthy drinking risk by bolstering self-efficacy to resist AOD use should consider the impact of recent cumulative exposure to sexual minority stressors in this population. Further, policy efforts are needed to reduce perpetuation of stigma.

This study explored how confidence in resisting alcohol and other drug (AOD) use relates to daily AOD use and unhealthy drinking risk among trauma-exposed sexual minority women (SMW) and transgender and gender-diverse (TGD) people. We also assessed whether experiences of minority stress, such as discrimination or stigma, influenced these relationships. Fifty-seven SMW and TGD individuals participated in a 14-day daily diary study. Results showed that higher self-efficacy was linked to lower AOD use and reduced unhealthy drinking risk. However, for those who experienced greater levels of minority stress over the 2 weeks, the protective effect of self-efficacy was weaker. In these cases, even high self-efficacy was less effective at reducing unhealthy drinking on stressful days. These findings suggest that interventions aimed at improving self-efficacy in resisting AOD use in SMW and TGD populations should address minority stressors, and policies need to focus on reducing stigma to improve health outcomes in these communities.

Daily challenge-hindrance stress and work engagement in preschool teacher: the role of affect and mindfulness.

BACKGROUND: The engagement of preschool teachers in their work is pivotal for maintaining teaching quality, ensuring teacher well-being, and fostering children's development. Despite its significance, there is limited knowledge regarding the daily fluctuations in work engagement and the underlying factors influencing it. This study, guided by the Job Demands-Resources model and Affect Event Theory, utilized an experience sampling methodology to investigate the impact of challenge and hindrance stressors on daily work engagement, as well as the mediating role of affect and the moderating effect of mindfulness. METHODS: Utilizing an experience sampling method, this study collected data from 220 preschool teachers in Shanghai over five consecutive workdays, conducting surveys once daily. Data analysis was performed using multilevel linear models. RESULTS: The results from multilevel regression indicated that: (1) daily challenge stressors were positively related to work engagement, (2) daily hindrance stressors were negatively related to work engagement, (3) daily positive affect mediated the relationship between challenge stressors and work engagement, (4) daily negative affect mediated the relationship between hindrance stressors and work engagement, and (5) daily mindfulness played a crucial moderating role by alleviating the adverse effects of hindrance stressors on daily negative affect. CONCLUSIONS: This study provides valuable insights into the daily experiences of preschool teachers and the factors that influence their work engagement. Understanding the impact of stressors, affect, and mindfulness on work engagement can inform the development of interventions and strategies to improve teacher well-being and work engagement.

Adolescent resilience in the face of COVID-19 stressors: the role of trauma and protective factors.

BACKGROUND: The COVID-19 pandemic introduced unique stressors that posed significant threats to adolescent mental health. However, limited research has examined the impact of trauma exposure on vulnerability to subsequent stressor-related mental health outcomes in adolescents. Furthermore, it is unclear whether there are protective factors that promote resilience against the negative impacts of COVID-19 stressors in adolescents with prior trauma exposure. This preregistered study aimed to investigate the impact of trauma on COVID-19 stressor-related mental health difficulties in adolescents, in addition to the role of protective factors. METHODS: Aims were investigated in a sample of 9696 adolescents (mean age 12.85 ± 0.88 years) from the Adolescent Brain Cognitive Development Study. Linear mixed-effects models were employed to examine (a) the associations of early trauma exposure (exposed v. non-exposed), COVID-19 stressors, and perceived stress, sadness, and positive affect levels during the pandemic period in the US, and (b) the role of protective factors (physical activity, parental support, and improvements in family and peer relationships) in these associations. RESULTS: There was a positive association between COVID-19 stressors and sadness, which was enhanced in trauma-exposed adolescents. Improvements in family and peer relationships mitigated the association between COVID-19 stressors and poor mental health outcomes, regardless of prior traumatic experience. CONCLUSIONS: These findings support the hypothesis that prior trauma elevates risk of mental health difficulties in the face of future stressors. Results underscore the protective role of enhanced social relationships as targets for early prevention and intervention in those experiencing acute stressors, regardless of prior traumatic experiences.

Stressors and suicidal ideation in low-income adults in Malaysia: A serial mediation analysis of social support and mental health symptoms.

BACKGROUND: Studies have documented a heightened risk of suicidal ideation in response to stressors, especially among people from socioeconomically disadvantaged backgrounds. However, the mechanisms of this association remain elusive. AIMS: Drawing on the social deterioration and counteractive models, this study aims to elucidate the pathways linking stressors to suicidal ideation through serial mediation of social support and mental health symptoms in Malaysia. METHOD: Data were collected from 404 low-income adults (33.2% male and 66.8% female) receiving monthly financial assistance from Malaysia's social welfare department. We employed stressor measures (i.e. financial, family and work), the Oslo Social Support Scale, the Patient Health Questionnaire and the Suicidal Behaviour Questionnaire-Revised. RESULTS: A total of 46.8% of participants reported mild-to-severe anxiety and depressive symptoms, with 11.1% classified as high risk for suicide. Direct and indirect effects were found. After controlling for age and gender, social support and mental health symptoms mediated the link between stressors and suicidal ideation. The serial mediation analysis indicates that stressors are connected to heightened suicidal ideation through a sequence involving insufficient social support, followed by elevated levels of mental health symptoms. CONCLUSION: Understanding the multifaceted relationships among stressors, social support, mental health symptoms and suicide ideation expands the potential for developing targeted interventions and preventive strategies tailored for vulnerable populations. Clinical work with low-income individuals may include implementing early systematic efforts to develop accessible mental health and integrated care services.

Synergistic interaction between a toxicant and food stress is further exacerbated by temperature.

Global biodiversity is declining at an unprecedented rate in response to multiple environmental stressors. Effective biodiversity management requires deeper understanding of the relevant mechanisms behind such ecological impacts. A key challenge is understanding synergistic interactions between multiple stressors and predicting their combined effects. Here we used Daphnia magna to investigate the interaction between a pyrethroid insecticide esfenvalerate and two non-chemical environmental stressors: elevated temperature and food limitation. We hypothesized that the stressors with different modes of action can act synergistically. Our findings showed additive effects of food limitation and elevated temperature (25°C, null model effect addition (EA)) with model deviation ratio (MDR) ranging from 0.7 to 0.9. In contrast, we observed strong synergistic interactions between esfenvalerate and food limitation at 20°C, considerably further amplified at 25°C. Additionally, for all stress combinations, the synergism intensified over time indicating the latent effects of the pesticide. Consequently, multiple stress substantially reduced the lethal concentration of esfenvalerate by a factor of 19 for the LC50 (0.45 to 0.024 µg/L) and 130 for the LC10 (0.096 to 0.00074 µg/L). The stress addition model (SAM) predicted increasing synergistic interactions among stressors with increasing total stress.

Stressors during the prodromal phase of major depressive episode (CHR-D).

Introduction: Early recognition and indicated prevention is a promising approach to decrease the incidence of Major depressive episodes (MDE), targeting the patients during their clinical high-risk state of MDE (CHR-D). The identification of a set of stressors at the CHR-D increases the success of indicated prevention with personalized early interventions. The study evaluated stressors in the early phase of depression, developed on the basis of a patient survey on stressors. Methods: Sixty-eight inpatients (ICD10: F3x.xx) with a reported high risk state for major depressive episode (CHR-D) were included in the current study. Stressors during CHR-D were retrospectively explored using a semi-structured clinical interview supplemented by open-ended questions. A qualitative explorative content analysis was provided to identify a pattern of stressors during the prodromal phase of the patients, based on the patient's perspective. A frequency analysis was performed for the evaluation of the prevalence of reported source of stress. Results: All patients reported stressors in the prodromal phase of depression. Results demonstrates that patients with depressive disorder typically report multiple stressors, with the most common number being four. First, 18 stressors-groups were identified during coding. Interpersonal conflicts and disappointments in close relationships were most frequently reported stressors during the prodromal phase at 44.1%. The second most frequent stressor mentioned was the high qualitative or quantitative demands at work (38.2%). The third frequent source of stress was changes in close relationships and in family relationships (33.8%). Based on the categories of stressors described in the patient survey during the prodromal phase we suggested a model of stressors in CHR-D during the prodromal phase of the MDE. Discussion: The identification of a set of stressors at the early stage of MDE may increase opportunities for early intervention. In everyday clinical practice, preventive psychiatry needs clinical and adapted instruments for recording stressors in today's society. This knowledge is necessary in order to develop precisely indicated prevention for depressive disorders.

Seizing the moments and lessons learned from the global response to COVID-19 pandemic: Creating a platform to shape the scientific and public discourse of research on adolescence.

COVID-19 response offers a model to guide research and preventive interventions targeting adolescents, their families, and communities. My 2022 SRA Presidential Address posed: What if the COVID-19 Response Served as a Guidepost for Future Research on Adolescence? Solution versus Problem-Focused Agenda. Several "pandemics" were already underway, emerging from historic and contemporary events that threaten the safety and survival of human lives. The Multi-Transgenerational Life Course Theoretical model was selected to demonstrate pathways through which the transmission of generational exposure to crisis and trauma impact adolescents' developmental trajectories. Recommendations to inform and guide an adolescent research rapid response agenda are proposed minds to advance equity and social justice can become realities.

Normalizing fentanyl: interpreting the perceived 'risk' of correctional officer work.

BACKGROUND: Scholarship on how fentanyl affects the complexities of correctional settings is limited in Canada, as scholars have focused on the prevalence of opioid use and overdose in prisons, as well as community treatment and access following release. Fentanyl constitutes a continuing challenge both in prisons and broader society. RESULTS: The current qualitative, interview-based empirical study examines how fentanyl is interpreted by correctional officers (COs, n = 99) across federal prisons in Canada, some of whom have worked in institutions with a high presence of fentanyl, while others have less exposure to the drug. We found that while many COs had responded to an overdose during their first or second year on the job, most COs who had did not perceive the event to be psychologically traumatic nor were concerned about the presence and availability fentanyl in their work environment, or they were indifferent. Yet this finding competes with the 41.4% of officers who did express concern about the presence of fentanyl - suggesting both a "normalization" of fentanyl as a workplace hazard as well as an underpinning social concern. CONCLUSIONS: We discuss the implications of these complicated findings in relation to reducing workplace stressors and countering misinformation that, in addition to other potential occupational factors, may be responsible for the concerns of COs tied to the presence of fentanyl.

Stress Attributes for Indian Orthodontic Practitioners: A Cross-sectional Study.

Background: Because orthodontists work long hours and maintain a relationship with each patient for many years prior to the end of treatment, they may encounter unusually stressful situations. Materials and Methods: A self-administered, anonymous survey was disseminated to orthodontic residents and practitioners in India. The survey includes 29 probable stressors. Result: Over 61% of respondents opined that these factors are the most stressful in orthodontic practice.

Wastewater and warming effects on aquatic invertebrates: Experimental insights into multi-level biodiversity consequences.

Wastewater effluents and global warming affect freshwater ecosystems and impact their crucial biodiversity. Our study aimed at characterizing individual and combined impacts of wastewater effluent and increased water temperature (as one aspect of climate change) on model freshwater communities. We tested the effect of experimental treatments on genetic diversity, survival, body weight, total lipid content, lipidome and metabolome of individual species as well as community composition and phylogenetic diversity. In a 21-day mesocosm experiment we assessed the responses of a simplified freshwater food web comprising of moss and seven species of benthic macroinvertebrate shredders and grazers (mayflies, stoneflies, caddisflies and amphipods) to four treatments in a full factorial design: control, increased water temperature, wastewater and a multiple stressor treatment combining increased temperature and wastewater. Physiological responses varied among taxa, with species-specific sensitivities observed in survival and lipid content. The lowest total lipid content was observed in caddisflies and a mayfly subjected to multiple stressor treatment. The effects of stressors were reflected in the altered metabolic pathways and lipid metabolism of the individual taxa, with differential treatment effects also observed between taxa. A notable decrease in phylogenetic diversity was observed across all experimental communities. Gammarus fossarum demonstrated a high susceptibility to environmental stressors at the genetic level. Hence, while commonly used indicators of ecosystem health (e.g. community composition) remained stable, molecular indicators (e.g. phylogenetic diversity, metabolome and lipidome) responded readily to experimental treatments. These findings underscore the vulnerability of macroinvertebrates to environmental stressors, even over relatively short exposure periods. They highlight the importance of molecular indicators in detecting immediate ecological impacts, offering valuable information for conservation strategies and understanding the ecological consequences in freshwater ecosystems.

Suicidal behaviors among refugee women in Jordan: post-traumatic stress disorder, social support and post-displacement stressors.

BACKGROUND: This paper examines the frequency of suicidal behaviors (suicidal ideation or attempt) among a sample of Syrian refugee women living in non-camp settings in Jordan. We asked several questions surrounding suicide and examined the associations between post-traumatic stress disorder (PTSD), social connectedness, post-displacement stressors and suicidal behaviors. METHODS: Participants (n = 507) were recruited using a clinic-based systematic sampling from four health clinics throughout Jordan in 2018. We used a multivariable logistic regression to examine the hypothesis of whether positive screening for PTSD (PCL-5), social isolation (have no friends or family members available to help), and greater number of post-displacement stressors (PMLD Checklist) is associated with suicidal behaviors. RESULTS: Approximately one-tenth (9.86%) of participants surveyed reported suicidal behaviors (suicidal ideation or attempt) in the past six months. Our hypothesis was partially supported. In the adjusted multivariable analyses, screening positive for PTSD [OR:4.02 (95% CI:1.33, 12.15)] increased odds of suicidal behaviors, while having one friend or family member available to help when in need [OR:0.31 (95% CI:0.13, 0.78)] decreased odds of suicidal behaviors. We did not find any associations between the number of post-displacement stressors and suicidal behaviors in the multivariable model. CONCLUSION: Agencies and practitioners addressing suicidal behaviors among Syrian refugee women should provide interventions that aim to reduce PTSD symptoms and social isolation. Potential intervention includes screening for mental health symptoms and suicidal behaviors during routine visits with service providers, as well as providing proper mental health and psychosocial support services according to the mapping of available services.

A Prospective Examination of Mental Health Trajectories of Disaster-Exposed Young Adults in the COVID-19 Pandemic.

This longitudinal study examines young adult mental health (MH) trajectories after exposure to natural disasters (i.e., hurricanes, wildfires, mudslides) across four waves, two pre- and two during the COVID-19 pandemic. Participants (n = 205) answered questions about anxiety, depression, and post-traumatic stress symptoms (PTSSs) across Waves (Ws) s 1-4 and pre-pandemic factors (prior trauma history, disaster exposure, life stressors since disaster) at Wave (W) 1. Hierarchical linear modeling was conducted to examine MH trajectories and associations with pre-pandemic factors. Only the PTSS trajectory significantly differed across all Ws, with the largest increase between Ws 2 and 3 (pre- and during-pandemic time points). Prior trauma history and life stressors since the disaster were significantly associated with all MH trajectory intercepts but not growth rates.

Importance of Prefabrication to Easing Construction Workers' Experience of Mental Health Stressors.

Construction is widely acknowledged for its socioeconomic contributions, although it is also always considered as a dangerous and incident-prone industry. As a new method of working, prefabrication presents better work environments and other benefits that can potentially improve the safety and mental health of construction workers. This study compares the extent of stressors in traditional and prefabricated construction. Eighty-four construction site and factory-based workers in Australia were surveyed. Prefabricated construction respondents reported less experience of industry-related, management/organisational, and personal stressors. Specifically, the stressors found to be weakened by prefabrication were mental fatigue, work injuries, poor working conditions, unfavourable shift rosters, work overload, and poor work-life balance. Furthermore, the degree of the experience of potential mental health improvement factors such as labour effort efficiency, reduced on-site trade overlap, increased mechanised construction, and less dependence on weather conditions, among others, was significantly higher in prefabrication than in traditional construction. The influence of prefabrication on measures of poor and positive mental health is recommended for further studies, particularly by finding its links with the different groups of construction workers.

Persistent low job control and subsequent major depression: A prospective cohort study of Australian working males.

Workers' perception of control over work is a key construct in the relationship between the psychosocial work environment and health. While exposure to low job control has been prospectively linked to poor mental health including depression and anxiety, there is less research examining the impact of prolonged exposure to low job control on mental health. Data from 5054 employed men from 2013 to 2021 in the Australian Longitudinal Study on Male Health was used to examine persistent and intermittent low job control and subsequent major depression symptoms. Persistent low job control was based on consecutive self-reports of low job control over waves 1 and 2. Combinations of low and high job control were classified as intermittent exposure and continuous high job control exposure over both waves was classified as persistent high job control. Major depression symptoms, derived from the Patient Health Questionnaire-9, was measured in wave 3. Generalised linear models and augmented inverse probability weighting were undertaken. There was a strong stepwise relationship between low job control and major depression. Compared to persistent high job control, intermittent low job control was associated with an increased risk of subsequent major depression symptoms by 32% (RR 1.32, 95% CI 0.82, 2.15); and persistent low job control by 103% (RR 2.03, 95% CI 1.21, 3.41). Compared to men exposed to persistent high job control, the average treatment effect for persistent low job control was 0.036 (95%CI 0.014, 0.058) and intermittent low job control 0.019 (95%CI 0.006, 0.032) equating to a risk ratio of 2.46 (95%CI 1.43, 3.50) and 1.79 (95% CI 1.14, 2.45) respectively. This study's findings have implications for public health and occupational policies, as they underscore the importance of reducing prolonged exposure to low job control to protect against the risk of major depression in the working population.
