Comparing Public Sentiment Toward COVID-19 Vaccines Across Canadian Cities: Analysis of Comments on Reddit.

BACKGROUND: Social media enables the rapid consumption of news related to COVID-19 and serves as a platform for discussions. Its richness in text-based data in the form of posts and comments allows researchers to identify popular topics and assess public sentiment. Nonetheless, the vast majority of topic extraction and sentiment analysis based on social media is performed on the platform or country level and does not account for local culture and policies. OBJECTIVE: The aim of this study is to use location-based subreddits on Reddit to study city-level variations in sentiments toward vaccine-related topics. METHODS: Comments on posts providing regular updates on COVID-19 statistics in the Vancouver (r/vancouver, n=49,291), Toronto (r/toronto, n=20,764), and Calgary (r/calgary, n=21,277) subreddits between July 13, 2020, and June 14, 2021, were extracted. Latent Dirichlet allocation was used to identify frequently discussed topics. Sentiment (joy, sadness, fear, and anger) scores were assigned to comments through random forest regression. RESULTS: The number of comments on the 250 posts from the Vancouver subreddit positively correlated with the number of new daily COVID-19 cases in British Columbia (R=0.51, 95% CI for slope 0.18-0.29; P<.001). From the comments, 13 topics were identified. Two were related to vaccines, 1 regarding vaccine uptake and the other about vaccine supply. The levels of discussion for both topics were linked to the total number of vaccines administered (Granger test for causality, P<.001). Comments pertaining to either topic displayed higher scores for joy than for other topics (P<.001). Calgary and Toronto also discussed vaccine uptake. Sentiment scores for this topic differed across the 3 cities (P<.001). CONCLUSIONS: Our work demonstrates that data from city-specific subreddits can be used to better understand concerns and sentiments around COVID-19 vaccines at the local level. This can potentially lead to more targeted and publicly acceptable policies based on content on social media.

The role of employee perceptions of safety priorities on safety outcomes across organisational levels.

Research has shown that safety climate predicts safety outcomes in various occupational settings. One important component of safety climate is employees' perceived priorities of safety in an organisation relative to other operational demands (e.g. productivity or efficiency). The relationships between three dimensions of employee perceptions of safety priorities (company, supervisor, worker), employee safety behaviour and self-reported injury outcomes were examined in the current study. Survey data were collected from 858 field workers (a response rate of 89%) at a TV-cable installation company. Results showed that all three dimensions of employee perceptions of safety priorities had significant and unique positive relationships with employee safety behaviour. Furthermore, safety behaviour was a significant mediator of the relationship between the three types of perceived safety priorities and missed work days due to workplace injury. The results showed the value of addressing employee perceptions of safety priorities across organisational levels when trying to improve workplace safety and reduce costly injuries. Practitioner Summary: The study examined relationships between the three different organisational levels of employee perceptions of safety priorities and employee safety behaviour and injury outcomes. The results demonstrated the value of addressing employee perceptions of safety priorities held by different levels of management as well as the worker level to improve workplace safety and reduce costly injuries.

Reduced Gonadotrophin Receptor Expression Is Associated with a More Aggressive Ovarian Cancer Phenotype.

Follicle-stimulating hormone (FSH) and luteinising hormone (LH) play important roles in regulating cell growth and proliferation in the ovary. However, few studies have explored the expression of FSH and LH receptors (FSHR and LHCGR) in ovarian cancer, and their functional roles in cancer progression remain inconclusive. This study investigated the potential impact of both mRNA (FSHR, LHCGR) and protein (FSHR, LHCGR) expression on ovarian cancer progression using publicly available online databases, qRT-PCR (high grade serous ovarian cancers, HGSOC, n = 29 and benign ovarian tumors, n = 17) and immunohistochemistry (HGSOC, n = 144). In addition, we investigated the effect of FSHR and LHCGR siRNA knockdown on the pro-metastatic behavior of serous ovarian cancer cells in vitro. High FSHR or high LHCGR expression in patients with all subtypes of high-grade ovarian cancer was significantly associated with longer progression-free survival (PFS) and overall survival (OS). High FSHR protein expression was associated with increased PFS (p = 0.050) and OS (p = 0.025). HGSOC patients with both high FSHR and high LHCGR protein levels had the best survival outcome, whilst both low FSHR and low LHCGR expression was associated with poorest survival (p = 0.019). Knockdown of FSHR significantly increased the invasion of serous ovarian cancer cells (OVCAR3 and COV362) in vitro. LHCGR knockdown also promoted invasion of COV362 cells. This study highlights that lower FSHR and LHCGR expression is associated with a more aggressive epithelial ovarian cancer phenotype and promotes pro-metastatic behaviour.

Barriers and Facilitators of Mental Health Treatment-Seeking in U.S. Active Duty Soldiers With Sexual Assault Histories.

Despite significant mental health needs among sexual assault (SA) victims in the military, little is known about treatment-seeking patterns or factors associated with service use. This study examined service use behavior, barriers, and facilitators of mental health treatment-seeking in an active duty sample of 927 U.S. Army soldiers with mental health problems. SA victims (n = 113) did not differ from non-victims on barriers or facilitators after adjusting for demographic and mental health variables, with stigma rated as the largest barrier. Most SA victims (87.6%) had sought informal support and 59.3% had sought formal treatment. One third of treatment-seekers had dropped out of treatment. Multivariate logistic regression analyses identified several correlates of treatment-seeking among SA victims: Black race (OR = 7.57), SA during the military (OR = 4.34), positive treatment beliefs (OR = 2.22), social support for treatment (OR = 2.14), self-reliance (OR = 0.47), and stigma towards treatment seekers (OR = 0.43). Mental health symptoms were not associated with treatment seeking. Findings suggested that treatment-facilitating interventions should focus on improving recognition of mental health symptoms, altering perceptions related to self-reliance, and reducing stigma. Interventions should also enlist support for treatment-seeking from unit members, leaders, and significant others.

A systematic review of the safety climate intervention literature: Past trends and future directions.

Safety climate represents the meaningfulness of safety and how safety is valued in an organization. The contributions of safety climate to organizational safety have been well documented. There is a dearth of empirical research, however, on specific safety climate interventions and their effectiveness. The present study aims at examining the trend of safety climate interventions and offering compiled information for designing and implementing evidence-based safety climate interventions. Our literature search yielded 384 titles that were inspected by three examiners. Using a stepwise process that allowed for assessment of interobserver agreement, 19 full articles were selected and reviewed. Results showed that 10 out of the 19 articles (52.6%) were based on a quasi-experimental pre- and postintervention design, whereas 42.1% (n = 8) studies were based on a mixed-design approach (including both between- and within-subject design). All interventions in these 19 studies involved either safety-/health-related communication or education/training. Improvement of safety leadership was also a common component of safety climate interventions. According to the socio-technical systems classification of intervention strategies, all studies were categorized as interventions focusing on improving organizational and managerial structure as well as the personnel subsystem; four of them also aimed at improving technological aspects of work, and five of them aimed at improving the physical work subsystem. In general, a vast majority of the studies (89.5%, n = 17) showed a statistically significant improvement in safety climate across their organizations postintervention.

Stigma at work: The psychological costs and benefits of the pressure to work safely.

INTRODUCTION: Workplace accidents and injuries can be quite costly to both individual employees and their organizations. While safety climate (i.e., perceptions of policies and procedures related to safety that should reflect an organization's value of safety) has been established as a predictor of safety behaviors, less research has considered the possible negative pressures that could result from an environment that emphasizes safety. Though organizations may intend to create a positive safety climate, concerns about being treated differently if an employee were to be involved in a safety incident may result in unintended, but detrimental safety and health outcomes. METHOD: This study investigated the stigma associated with being involved in a safety-related incident in relation to self-reported safety behaviors and psychological health outcomes. The data were acquired through a two-wave prospective design, surveying workers from Amazon Mechanical Turk (MTurk; N = 528) who indicated they were exposed to at least one physical work stressor (e.g., heavy lifting; air quality; standing for extended periods) a few times each month or more. RESULTS: When controlling for safety climate, safety stigma was related to decreased safety compliance and poorer psychological health. There was a marginally significant interaction between safety stigma and safety motivation in relation to safety compliance. CONCLUSIONS: These findings suggest that experiencing pressure to work safely, for fear of being evaluated negatively, may actually come at the cost of employees' safety compliance and psychological health. Practical applications: These results may be useful in assessing and intervening to improve an organization's safety climate. Organizations should closely examine the climate for safety to ensure that positive aspects of safety are not undermined by a stigmatizing pressure associated with safety in the work environment.

Economic stress and well-being: Does population health context matter?

The purpose of this study was to investigate the role of county-level population health determinants in predicting individual employee reactions to economic stress. Using multilevel modeling and a population health perspective, we tested a model linking nationally representative individual-level data (N = 100,968) on exposure to economic stressors and county-level population health determinants (N = 3,026) to responses on a composite measure of individual well-being that included the facets of purpose, community, physical, and social well-being, as well as life satisfaction. Results indicate that higher income- and employment-related economic stress were significantly related to poorer well-being. Additionally, living in a county with more positive population health determinants was significantly predictive of individual well-being. Finally, the Level-1 relationship between income-related stress and well-being was significantly attenuated for individuals living in counties with more positive population health determinants. In contrast, employment-related stress had a stronger negative relationship with well-being for individuals who lived in counties with more positive population health determinants. We discuss these findings in light of conservation of resources and relative deprivation theories, as well as how they may extend the scientific foundation for evidence-based social policy and evidence-based intervention programs aimed at lessening the effects of economic stress on individual well-being.

Does talking the talk matter? Effects of supervisor safety communication and safety climate on long-haul truckers' safety performance.

This study examines the distinct contribution of supervisory safety communication and its interaction with safety climate in the prediction of safety performance and objective safety outcomes. Supervisory safety communication is defined as subordinates' perceptions of the extent to which their supervisor provides them with relevant safety information about their job (i.e., top-down communication) and the extent to which they feel comfortable discussing safety issues with their supervisor (i.e., bottom-up communication). Survey data were collected from 5162 truck drivers from a U.S. trucking company with a 62.1% response rate. Individual employees' survey responses were matched to their safety outcomes (i.e., lost-time injuries) six months after the survey data collection. Results showed that the quality of supervisor communication about safety uniquely contributes to safety outcomes, above and beyond measures of both group-level and organization-level safety climate. The construct validity of a newly-adapted safety communication scale was demonstrated, particularly focusing on its distinctiveness from safety climate and testing a model showing that communication had both main and moderating effects on safety behavior that ultimately predicted truck drivers' injury rates. Our findings support the need for continued attention to supervisory safety communication as an important factor by itself, as well as a contingency factor influencing how safety climate relates to safety outcomes.

An item-response theory approach to safety climate measurement: The Liberty Mutual Safety Climate Short Scales.

Zohar and Luria's (2005) safety climate (SC) scale, measuring organization- and group- level SC each with 16 items, is widely used in research and practice. To improve the utility of the SC scale, we shortened the original full-length SC scales. Item response theory (IRT) analysis was conducted using a sample of 29,179 frontline workers from various industries. Based on graded response models, we shortened the original scales in two ways: (1) selecting items with above-average discriminating ability (i.e. offering more than 6.25% of the original total scale information), resulting in 8-item organization-level and 11-item group-level SC scales; and (2) selecting the most informative items that together retain at least 30% of original scale information, resulting in 4-item organization-level and 4-item group-level SC scales. All four shortened scales had acceptable reliability (≥0.89) and high correlations (≥0.95) with the original scale scores. The shortened scales will be valuable for academic research and practical survey implementation in improving occupational safety.

Carrots, Not Sticks: Adverse Impact and Wellness Programs.

OBJECTIVE: The purpose of this study was to determine if wellness programs are likely to produce an adverse impact in various protected groups and to determine what features of the program may contribute to adverse impact. METHODS: Using a nationally representative sample of US adults, we examined the proportions of protected groups that would be expected to encounter adverse impact using various health factors such as weight, blood pressure, and cholesterol levels. RESULTS: The results of this study indicate that disincentive-based programs pose a high risk of differentially selecting protected groups into program categories. This is especially true for members of multiple protected classes. CONCLUSIONS: We suggest organizations carefully consider both the type of program and the health factors incorporated into their wellness efforts and use incentives rather than disincentives to encourage health promotion.

Money Matters: Recommendations for Financial Stress Research in Occupational Health Psychology.

Money is arguably the most important resource derived from work and the most important source of stress for contemporary employees. A substantial body of research supports the relationship between access to financial resources and health and well-being, both at individual and aggregated (e.g. national) levels of analysis. Yet, surprisingly little occupational health psychology research has paid attention to financial issues experienced specifically by those in the labour force. With these issues in mind, the overarching goal of the present paper was to address conceptual and measurement issues in the study of objective and subjective aspects of financial stress and review several assessment options available to occupational health psychology researchers for both aspects of financial stress. Where appropriate, we offer guidance to researchers about choices among various financial stress measures and identify issues that require further research attention.

Correlates and reasons for mental health treatment dropout among active duty soldiers.

Many soldiers who seek treatment for mental health problems drop out of treatment before it is complete. The present study examined factors that are associated with dropout among active duty soldiers. Soldiers who had sought treatment (N = 260) responded to measures of beliefs about mental health treatment, mental health symptoms, treatment-seeking behaviors, and treatment dropout. Fifty-seven soldiers reported dropping out before treatment was completed. Commonly endorsed reasons for dropout were that soldiers were too busy with work and a preference to handle the symptoms oneself. A series of logistic regressions revealed that depression symptoms (odds ratio [OR] = 1.07), functional impairment (OR = 1.49), career stigma (OR = 1.70), differential treatment stigma (OR = 1.62), practical barriers (OR = 1.76), negative beliefs about treatment (OR = 1.98), and self-reliance (OR = 1.78) were associated with an increased likelihood of dropout. Positive beliefs about treatment were associated with a decreased likelihood of dropout (OR = 0.60). Functional impairment, career stigma, and self-reliance remained unique predictors in a final forward conditional regression. These findings highlight the need for interventions to support service members in treatment by educating them on the benefits of treatment and reducing practical barriers. (PsycINFO Database Record

Beyond safety outcomes: An investigation of the impact of safety climate on job satisfaction, employee engagement and turnover using social exchange theory as the theoretical framework.

Safety climate, a measure of the degree to which safety is perceived by employees to be a priority in their company, is often implicated as a key factor in the promotion of injury-reducing behavior and safe work environments. Using social exchange theory as a theoretical basis, this study hypothesized that safety climate would be related to employees' job satisfaction, engagement, and turnover rate, highlighting the beneficial effects of safety climate beyond typical safety outcomes. Survey data were collected from 6207 truck drivers from two U.S. trucking companies. The objective turnover rate was collected one year after the survey data collection. Results showed that employees' safety climate perceptions were linked to employees' level of job satisfaction, engagement, and objective turnover rate, thus supporting the application of social exchange theory. Job satisfaction was also a significant mediator between safety climate and the two human resource outcomes (i.e., employee engagement and turnover rate). This study is among the first to assess the impact of safety climate beyond safety outcomes among lone workers (using truck drivers as an exemplar).

Do Job Demands of Chinese Manufacturing Employees Predict Positive or Negative Outcomes? A Test of Competing Hypotheses.

Karasek's job demands-control (JDC) model posits that job control can buffer against the harmful effects of demands experienced by employees. A large volume of JDC research has obtained support for the main effects of demands and control, but not the interactive effects. Recent research on the challenge-hindrance stressors framework, however, found that work stressors may not always be deleterious, suggesting alternative hypotheses about the effects of demands and control. The present study therefore examined competing hypotheses concerning the effects of job demands on occupational health outcomes. Using a sample of 316 employees in a Chinese manufacturing company, we found that, consistent with the challenge-hindrance framework, production demands were challenge stressors associated with favourable outcomes (i.e. job satisfaction and psychological well-being). In addition, results showed that the interactive role of job control depended on the nature of outcome variables. Future recommendations and implications of findings are discussed.

The role of different stigma perceptions in treatment seeking and dropout among active duty military personnel.

OBJECTIVE: Many military personnel with mental health problems do not seek treatment from mental health professionals, and if they do seek treatment, they drop out of treatment before receiving the recommended number of sessions. The present study examined the role of 4 different stigma perceptions on these outcomes: perceived stigma to career, perceived stigma of differential treatment, self-stigma from seeking treatment, and stigmatizing perceptions of soldiers who seek treatment. METHOD: One thousand three hundred twenty-four active duty soldiers completed a self-report survey assessment that included measures of the 4 different stigma perceptions, indices of mental health symptoms, receipt of mental health treatment, and whether they had dropped out of treatment before it was completed. RESULTS: Participants screening positive for a mental health problem reported higher scores on all 4 stigma perceptions. All 4 stigma perceptions were each associated with a reduced likelihood of treatment seeking when considered individually, but only stigmatizing beliefs about those who seek treatment were uniquely associated with treatment seeking. Perceived stigma for one's career and differential treatment from others, along with self-stigma from treatment seeking, were associated with an increased probability of dropping out of mental health treatment. Self-stigma from treatment seeking was the only unique predictor of dropout. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Different stigma perceptions were associated with treatment seeking and dropout. Further longitudinal research is needed to examine how stigma perceptions influence these important outcomes. Practitioners need to be aware of how different stigma perceptions can influence treatment seeking and potentially target stigma perceptions during treatment to prevent dropout.

"The role of different stigma perceptions in treatment seeking and dropout among active duty military personnel": Correction to Britt et al. (2015).

UNLABELLED: Reports an error in "The role of different stigma perceptions in treatment seeking and dropout among active duty military personnel" by Thomas W. Britt, Kristen S. Jennings, Janelle H. Cheung, Cynthia L. S. Pury and Heidi M. Zinzow (Psychiatric Rehabilitation Journal, 2015[Jun], Vol 38[2], 142-149). Six participants were included in the sample for the treatment-seeking analyses who scored 50 or above on the PTSD Checklist, but did not meet the specific criteria on the three PTSD subscales. Of these six participants, four screened positive for another problem. Removing the two participants who did not screen positive for another problem did not affect the significance of any of the predictors in the analyses. (The following abstract of the original article appeared in record 2015-12033-001.) OBJECTIVE: Many military personnel with mental health problems do not seek treatment from mental health professionals, and if they do seek treatment, they drop out of treatment before receiving the recommended number of sessions.

How are perceived stigma, self-stigma, and self-reliance related to treatment-seeking? A three-path model.

OBJECTIVE: Many college students may experience mental health problems but do not seek treatment from mental health professionals. The present study examined how perceived stigma and self-stigma toward seeking mental health treatment, as well as perceptions of self-reliance for coping with mental health problems, relate to college student treatment-seeking. METHOD: In total, 246 students completed a self-report survey that included measures of perceived stigma and self-stigma for treatment-seeking, self-reliance for addressing mental health concerns, self-reported mental health problems, symptoms of depression and alcohol-related problems, attitudes toward treatment-seeking, and treatment-seeking behavior. RESULTS: Regression analyses revealed that higher perceived stigma, self-stigma, and self-reliance were all related to a more negative attitude toward treatment-seeking. In a 3-path mediation model, bootstrapping results indicated an indirect effect where perceived stigma was related to attitude toward treatment-seeking and treatment-seeking behaviors through self-stigma and self-reliance. Specifically, higher perceived stigma was related to higher self-stigma, higher self-stigma was related to higher self-reliance, and higher self-reliance was associated with a more negative attitude toward treatment-seeking in the overall sample, and a decreased probability of having sought treatment among those who screened positive for a mental health problem. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Perceived stigma may influence whether or not college students seek treatment for mental health problems by potentially increasing stigmatizing attitudes toward themselves and increasing preferences for handling problems on their own. Researchers and practitioners are recommended to seek a better understanding of the complex treatment barriers to reduce stigma and facilitate treatment-seeking.
