A systematic review and meta-analytic confirmatory factor analysis of the perceived stress scale (PSS-10 and PSS-14)

Profiles of objective and subjective cognitive function in Post-COVID Syndrome, COVID-19 recovered, and COVID-19 naïve individuals

Post-COVID Syndrome has emerged as a significant public health concern worldwide with increasing evidence to suggest that individuals who have had an acute COVID-19 infection report lingering memory and attention difficulties, even in individuals who have fully recovered and no longer experiencing symptoms of COVID-19. The present study sought to investigate the profile of objective and subjective cognitive difficulties in people who have Post-COVID Syndrome, people who have fully recovered from an acute COVID infection and people who have never had COVID-19. We further sought to explore the extent to which self-reported fatigue and stress are related to subjective and objective cognitive difficulties. 162 participants including 50 people living with Post-COVID Syndrome, 59 people who have had COVID-19 but have fully recovered and 53 people who have never experienced symptoms of COVID-19 and had never tested positive for COVID-19 were recruited from Academic Prolific to complete a series of online questionnaires and neurocognitive tasks. Subjective cognitive function was measured using the Cognitive Failures Questionnaire and objective cognitive function was measured using the Cognitron cognitive test battery. We found that objective and subjective measures of cognitive function were not significantly related, suggesting that self-reports of "brain fog" are not reflecting objectively measured cognitive dysfunction. A MANOVA revealed that subjective cognitive deficits were driven by heightened perceived stress and fatigue and not significantly related to COVID-19 status. Objective cognitive function, however, was significantly related to perceived stress and COVID status whereby we observed significant objective cognitive deficits in people who have been exposed to an acute COVID-19 infection regardless of whether they had Post-COVID Syndrome or had fully recovered, as compared to people who had never had COVID-19. This suggests that an acute infection can have long term effects on cognitive function, even without persistent COVID-19 symptoms. Encouragingly, objective cognitive function was significantly associated with time since initial infection showing that cognitive deficits improved over time for people who had recovered from COVID-19. However, we did not observe the same improvement in individuals with Post-COVID Syndrome and observed that cognitive dysfunction was significantly related to the number of neurological symptoms presently experienced. These results add to the accumulating literature that COVID-19 is associated with significant cognitive difficulties following a COVID-19 infection, which appear to improve over time for those who have recovered from COVID-19 yet persist in people living with Post-COVID Syndrome.

Burnout among elementary and high school teachers in three Canadian provinces: prevalence and predictors

Background

Burnout is a longstanding issue among educators and has been associated with psychological and physical health problems such as depression, and insomnia.

Objective

To assess the prevalence and predictors of the three dimensions of burnout (emotional exhaustion, depersonalization and lack of professional accomplishment) among elementary and high school teachers.

Methods

This is a quantitative cross-sectional study with data collected via an online survey. The Maslach Burnout Inventory-Educator Survey (MBI-ES), the Brief Resilience Scale (BRS) and the Perceived Stress Scale were used, respectively, to assess burnout, resilience and stress among teachers. Data was collected between September 1st, 2022 and August 30th, 2023. SPSS (version 28, IBM Corp) was used for the data analysis.

Results

Overall, 1912 educators received a link to the online survey via a text message, and 780 completed the burnout survey questions, resulting in a response rate of 41%. The prevalence of emotional exhaustion, depersonalization, and lack of professional accomplishment were 76.9, 23.2, and 30.8%, respectively. Participants with high-stress symptoms were 6.88 times more likely to experience emotional exhaustion (OR = 6.88; 95% CI: 3.31-14.29), 2.55 times (OR = 2.55; 95% CI: 1.65-3.93) more likely to experience depersonalization and 2.34 times (OR = 2.34; 95% CI: 1.64-3.35) more likely to experience lack of professional fulfilment. Additionally, respondents with low resilience were 3.26 times more likely to experience emotional exhaustion symptoms (OR = 3.26; 95% CI: 2.00-5.31), than those with high resilience. Males were about 2.4 times more likely to present with depersonalization compared to female teachers, whilst those who indicated their marital status as partnered or cohabiting and those who selected "other" were 3.5 and 7.3 times, respectively, more likely to present with depersonalization compared with those who were single. Finally, Physical Education were 3.8 times more likely to present with depersonalization compared with English teachers.

Conclusion

The current study highlights the predictive effects of low resilience and high stress on the three dimensions of burnout among teachers in Canada. Interventions aimed at addressing systemic stress and fostering resilience are needed to reduce burnout among teachers.

Perceived Stress Mediates Associations Between Grit and Health-Related Quality of Life

Grit, characterized by passion and perseverance in the pursuit of long-term goals, may be associated with enhanced quality of life and reduced levels of perceived chronic stress. We hypothesized that reduced levels of perceived stress may mediate the association between facets of grit (i.e., Perseverance and Consistency) and healthy functioning. We conducted two studies, one with college students and one with community adults, to test this hypothesis (cumulative N = 600). In both studies, facets of grit were assessed using the Short Grit Scale, levels of perceived chronic stress were assessed via the Perceived Stress Scale, and health-related quality of life was measured using selected questions from the Medical Outcome Study Short Form-36. Consistent with our hypothesis, perceived stress levels significantly mediated the relation between Grit-Perseverance and health-related quality of life in both college students and community adults. Our data suggest that individuals with high Grit-Perseverance experience lower perceived stress, which may result in improved health-related quality of life. Additionally, perceived stress partially mediated the relation between Grit-Consistency and health-related quality of life, but only in community adults. These novel findings suggest that the association between Grit-Perseverance and perceived chronic stress may differ for college students and community adults. Overall, our work indicates that perceived stress may be a key mediator through which facets of grit are related to healthy functioning in college students and community adults.

Trajectories of intimate partner violence and their relationship to stress among young women in South Africa: An HPTN 068 study

BACKGROUND

One in four South African women will experience intimate partner violence (IPV) in their lifetime, potentially increasing their biological stress. In South Africa, limited IPV and stress research has utilized multiple timepoints or examined modifying factors. Cash transfers (CTs) are associated with reduced IPV and stress and may be an intervention target.

AIMS

We used data-driven methods to identify longitudinal IPV trajectory groups among South African adolescent girls and young women (AGYW), estimate each group's association with stress, and assess modification by a CT.

METHODS

A total of 2,183 South African AGYW ages 13 to 24 years from the HIV Prevention Trials Network 068 study were randomized to a CT or control group. Physical IPV was measured five times (2011-2017), and stress was captured once (2018-2019). Stress measures included the Cohen Stress Scale and stress biomarkers (C-reactive protein (CRP), cytomegalovirus (CMV), herpes simplex virus type-1 (HSV-1)). Group-based trajectory modeling identified IPV trajectories; ordinal logistic regression estimated the association between trajectory group and stress.

RESULTS

A two-group quadratic trajectory model was identified (higher trajectory group = 26.7% of AGYW; lower trajectory group = 73.3%). In both groups, the probability of IPV increased from ages 13 to 17 years before declining in early adulthood. However, the higher group's probability peaked later and declined gradually. The higher trajectory group was associated with an increased odds of elevated CRP (OR: 1.41, 95% CI [1.11, 1.80]), but not with other stress measures. The CT modified the relationship with CMV: a positive association was observed among the usual care arm (OR: 1.59, 95% CI [1.11, 2.28]) but not the CT arm (OR: 0.85, 95% CI [0.61, 1.19]).

CONCLUSIONS

Sustained IPV risk during adolescence was associated with elevated CRP in young adulthood. The relationship between IPV and elevated CMV was attenuated among those receiving a CT, suggesting that CTs could possibly reduce biological stress due to IPV.

Enhancing sexual health and empowerment among migrant women sex workers: a community health worker-led intervention in Marseille, France

Introduction

Given the high infection rate of sexually transmitted infections (STI) among migrant women sex workers (WSWs), it is necessary to understand how to improve prevention, information and care for this vulnerable population. Community health workers (CHWs), by linking community to health services, are positioned to improve health outcomes in migrant communities. This article aims to describe a pilot innovative intervention performed by CHWs to improve sexual health in migrant WSWs.

Methods

This one-year intervention study used a respondent-driven sampling (RDS) to recruit a representative cohort of migrant WSWs in Marseille, France. Four CHWs were recruited from different communities and participated in all stages of the research. They performed individual and group interventions of prevention, support in care and empowerment. Data on participant characteristics, type of intervention and adherence to the intervention were reported via questionnaires given to participants. Simultaneously, semi-structured interviews and informal interviews of migrant WSW, CHWs and care providers were carried out.

Results

A total of 132 migrant WSWs were included in the cohort. Very few of them knew about PrEP (12%) or already used HIV post-exposure treatment (9%). Migrant WSWs were often victims of rape or racism, 15 and 21%, respectively. In two-thirds of cases the level of health literacy was low. Participants suffered from a combination of vulnerability factors: difficulties with access to social rights, food or housing. Only 13% reported having benefited from medical follow-up or assistance by an NGO in the 3 months prior to the program. By 3 months, more than one third of the participants had been tested for HIV (35%) and 63% knew about PrEP. A total retention rate of 70% was reported in the cohort after 6 months.

Conclusion

CHWs enabled to improve care access for migrant WSWs by improving the collaboration between care and social actors at a local level. Through these "bring-back-to" interventions for this hard-to-reach population, CHWs enabled an optimization of the care pathway. Our results also highlight the importance of a population-based approach for individual and group support of empowerment interventions in order to strengthen their capacity for action.

Evaluation of the psychometric properties of the Italian version of the 10-item perceived stress scale in a sample of teachers

Background

The 10-item Perceived Stress Scale is a widely used questionnaire for measuring perceived stress.

Aim

This study aimed to assess the psychometric properties of the Italian version of the 10-item Perceived Stress Scale in a sample of Italian teachers during the COVID-19 pandemic.

Methods

A cross-sectional study was performed. A sample of 1,179 teachers of pre-primary, primary, and secondary schools anonymously completed an online questionnaire. A Confirmatory Factor Analysis was performed to compare the fit of a two-factor model against a one-factor solution of the scale. Multigroup CFA was run to test the measurement invariance of the two-factor PSS-10 solution across gender. The internal reliability of the scale was evaluated using Cronbach's alpha and McDonald' omega coefficients. Convergent validity with measures of subjective well-being and self-reported health was evaluated.

Results

The results of the Confirmatory Factor Analysis showed that the two-factor structure of the 10-items Perceived Stress Scale provided a better fit to the data and supported the adequacy of the Italian version of the scale. The two-factor model showed measurement invariance across female and male groups, as result of the multigroup CFA. The scale proved to have good internal reliability. Correlation analyses with measures of the Positive Affect and Negative Affect Schedule and self-reported health supported convergent validity.

Conclusion

These results suggest that the Italian version of the 10-item Perceived Stress Scale has good psychometric properties and can be considered a valid and reliable instrument to assess perceived stress.

Non-Cognitive Adaptive Resourcefulness: Scrutiny of Its Multidimensionality and Nomological Validity

Recent research has observed that Mental Toughness, Optimal Regulation, and Self-Efficacy share core features and variance. Investigators have named this commonality Non-Cognitive Adaptive Resourcefulness (NCAR). The NCAR validation study reported that the construct possesses promising psychometric properties, however, further research is required to replicate and extend these findings. Acknowledging this, the present paper using a UK-based sample of 1998 participants (Mage = 40 years, range 18-83), tested the NCAR model against competing alternatives (multidimensional and one-factor solutions), and assessed the nomological validity of NCAR in relation to Perceived Stress and Anxiety Control. Participants completed the self-report study measures online. Exploratory structural equation modelling revealed that a bifactor solution represented data more effectively than one-factor and multi-factor alternatives. Additionally, a structural equation model found that NCAR significantly predicted Perceived Stress (subfactors of Distress and Coping) and Anxiety Control (subfactors of Emotional Control, Threat Control, and Stress Control). Moreover, NCAR predicted PSS Coping and Emotional Control to a greater extent than the specific bifactors (Mental Toughness, Optimal Regulation, and Self-Efficacy). This suggested that NCAR comprises an underpinning, positive psychological energy that facilitates coping. Particularly, an enabling resource that enhances the capacity to thrive under pressure and retain emotional control in demanding and trying circumstances.
