The perceived stress scale (PSS): normative data and factor structure for a large-scale sample in Mexico

Genetic Evidence of Endocannabinoid System on Perceived Stress and Restricted Food Intake: The Role of Variants rs324420 in FAAH Gene and rs1049353 in CNR1 Gene

Background: The endocannabinoid system (ECS) is active in brain regions involved in stress, food intake, and emotional regulation. The CB1 receptor and the fatty acid amide hydrolase (FAAH) enzyme regulate the ECS. Genetic variants in the FAAH gene (rs324420) and in the CNR1 gene (rs1049353) have been involved in both chronic stress and obesity. As a maladaptive strategy to evade the stress, three dysfunctional eating patterns may appear: cognitive restriction, disinhibition, and emotional eating. Aim: To evaluate the association of variants rs324420 in the FAAH gene and rs1049353 in the CNR1 gene with perceived stress, dysfunctional eating patterns, and anthropometric and body composition variables. Methods: This cross-sectional study included 189 participants from western Mexico. The Spanish version of the Three-Factor Eating Questionnaire and the Perceived Stress Scale were applied. Genotyping was performed with TaqMan® probes. Results: It was found that subjects with CA/AA genotypes in FAAH had a higher risk of presenting high scores in stress perception than CC genotype carriers (odds ratio [OR] 1.85, 95% confidence interval [CI] 1.007-3.339; p = 0.048); in addition, the CC genotype of this genetic variant was related to higher body weight and body fat, but no association was found with dysfunctional eating patterns. As for the CNR1 single-nucleotide polymorphism, this variant showed no significant association with stress perception scores, but subjects with GA/AA genotypes in CNR1 had a lower risk of presenting high scores of restriction in food intake compared with GG genotype carriers (OR 0.11, 95% CI 0.046-0.322; p < 0.001). Therefore, this study suggests a differential role of the ECS genes FAAH and CNR1 in perceived stress and dysfunctional eating patterns, respectively. Further studies in other populations are required.

Internet-based self-administered intervention to reduce anxiety and depression symptomatology and improve well-being in 7 countries: protocol of a randomized control trial

Background

Online psychological interventions have emerged as a treatment alternative because they are accessible, flexible, personalized, and available to large populations. The number of Internet interventions in Latin America is limited, as are Randomized Controlled Trials (RCTs) of their effectiveness and a few studies comparing their effectiveness in multiple countries at the same time. We have developed an online intervention, Well-being Online, which will be available to the public free of charge in 7 countries: Mexico, Ecuador, Peru, Chile, Brazil, Spain, and the Netherlands. We expect a reduction in depression and anxiety symptoms and an increase in well-being of the participants.

Methods

A multi-country, randomized controlled trial will be conducted. The intervention is multicomponent (Cognitive Behavioral Therapy, Behavioral Activation Therapy, Mindfulness, Acceptance and Commitment Therapy, and Positive Psychology), with 10 sessions. In each country, eligible participants will be randomized to one of three groups: Enriched Intervention (interactive web design with videos, infographics, text, audio, and forum), Text Intervention (text on the website), and Wait List (control group). Repeated measures will be obtained at 5-time points. Our primary outcomes will be anxiety symptomatology, depressive symptomatology, and mental well-being. MANOVA analysis will be used for our main analysis.

Discussion

This protocol describes the design of a randomized trial to evaluate the efficacy of a web-based intervention to reduce anxiety and depression symptomatology and increase subjective well-being. The intervention will be made available in four languages (Spanish, Portuguese, Dutch, and English). Its results will contribute to the evidence of effectiveness in terms of randomized trials and Internet interventions, mainly in Latin America and Europe.

Psychometric properties of the Perceived Stress Scale (PSS-10) in silica-exposed workers from diverse cultural and linguistic backgrounds

BACKGROUND

The Perceived Stress Scale (PSS-10) has been used in a range of occupational cohorts, but only recently in stone benchtop workers undergoing screening for silicosis. The aim of this study was to compare psychometric properties of the PSS-10 in stone benchtop workers amongst those born overseas or who used an interpreter.

METHODS

Stone benchtop workers in Melbourne, Australia completed the PSS-10 as part of their occupational screening for silicosis. Internal consistency was assessed with Cronbach's α for the total score and the positive and negative subscales. Validity was assessed using confirmatory factor analysis (CFA). Analysis was performed for the total group and for subgroups according to sex, interpreter use, overseas-born, and language spoken at home.

RESULTS

The results of 682 workers with complete PSS-10 scores were included in analysis. Most participants were male (93%), with mean age 36.9 years (SD 11.4), with just over half (51.6%) born in Australia, 10.1% using an interpreter, and 17.5% using a language other than English at home. Cronbach's α for the overall group (α = 0.878) suggested good internal consistency.

DISCUSSION

CFA analysis for validity testing suggested PSS-10 performance was good for both sexes, moderate for country of birth and language spoken at home categories, but poorer for those who used an interpreter. Whilst professional interpreters provide a range of benefits in the clinical setting, the use of translated and validated instruments are important, particularly in cohorts with large numbers of migrant workers.

CONCLUSION

This study describes the psychometric properties of the PSS-10 in a population of stone benchtop workers, with good internal consistency, and mixed performance from validity testing across various subgroups.

Perceived stress, coping strategies, symptoms severity and function status among carpal tunnel syndrome patients: a nurse-led correlational Study

BACKGROUND

Carpal tunnel syndrome (CTS) is a prevalent condition characterized by hand pain, tingling, and numbness. The severity of symptoms and functional status in CTS patients may be influenced by perceived stress and how individuals cope with it. However, scarce knowledge exists about the role of coping strategies as moderators in this relationship. Unfolding the role of perceived stress and coping strategies for CTS management will help the nurse to provide comprehensive and tailored nursing care. This will ultimately improve patient comfort, functionality, and quality of life.

PURPOSES

This study aimed to examine the role of coping strategies (adaptive and maladaptive) in the relationship between perceived stress and both symptoms severity and function status among those patients.

METHOD

We employed a multisite, correlational study design with moderation analysis. The study included 215 patients with CTS from neurosurgery outpatient clinics at three hospitals in Egypt. After obtaining their consent to participate, eligible participants completed anonymous, self-reported measures of perceived stress, the brief COPE inventory, and the Boston Carpal Tunnel Questionnaire. Demographic and biomedical data were also collected. The questionnaire took about 20 min to be completed. The data was collected over six months, starting in February 2023.

RESULTS

The results showed that perceived stress, adaptive coping, and maladaptive coping were significant predictors of symptoms severity and functional status. Adaptive coping moderated the relationships between perceived stress and both symptoms severity and function status, while maladaptive coping did not. The interaction between perceived stress and adaptive coping explained a moderate effect on symptoms severity and function status after controlling for the main effects and the covariates.

CONCLUSION

This study explored the relationship between perceived stress, coping strategies, and outcomes in patients with CTS. The results indicate that nurses play a vital role in assessing and assisting patients to adopt effective coping strategies to manage perceived stress and alleviate symptoms and functional impairment. Moreover, the findings support the need for psychological interventions that address both perceived stress and coping strategies as a way to enhance the functioning status and quality of life of patients with CTS.

Does Osteopathic Heart-Focused Palpation Modify Heart Rate Variability in Stressed Participants with Musculoskeletal Pain? A Randomised Controlled Pilot Study

Heart rate variability (HRV) describes fluctuations in time intervals between heartbeats and reflects autonomic activity. HRV is reduced in stressed patients with musculoskeletal pain and improved after osteopathic manipulative treatment and mind-body interventions. Heart-focused palpation (HFP) combines manual and mind-body approaches to facilitate relaxation. This randomised controlled pilot study investigated the feasibility and sample size for a future randomised controlled trial and the effect of a single treatment with HFP or sham HFP (SHAM) on short-term HRV. A total of Thirty-three adults (47.7 ± 13.5 years old) with stress and musculoskeletal pain completed the trial with acceptable rates of recruitment (8.25 subjects per site/month), retention (100%), adherence (100%), and adverse events (0%). HFP (n = 18), but not SHAM (n = 15), significantly increased the root mean square of successive RR interval differences (p = 0.036), standard deviation of the NN intervals (p = 0.009), and ratio of the low-frequency to high-frequency power band (p = 0.026). HFP and SHAM significantly decreased the heart rate (p < 0.001, p = 0.009) but not the stress index and ratio of the Poincaré plot standard deviation along and perpendicular to the line of identity (p > 0.05). A power analysis calculated 72 participants. Taken together, the study was feasible and HFP improved HRV in stressed subjects with musculoskeletal pain, suggesting a parasympathetic effect.

Adverse Childhood Experiences and Higher Levels of Stress Are Associated With the Co-occurrence of Cancer-Related Cognitive Impairment and Anxiety

OBJECTIVES

We sought to identify subgroups of patients with distinct joint cancer-related cognitive impairment (CRCI) AND anxiety profiles and evaluate for differences in demographic and clinical characteristics, as well as levels of global stress, cancer-specific stress, cumulative life stress, and resilience.

DATA SOURCES

Patients (n = 1332) completed the Attentional Function Index and the Spielberger State Anxiety Inventory six times over two cycles of chemotherapy. Global, cancer-specific, and cumulative life stress and resilience were evaluated using Perceived Stress Scale, Impact of Event Scale-Revised, Life Stressor Checklist-Revised, and Connor-Davidson Resilience Scale, respectively. Latent profile analysis was used to identify subgroups of patients with distinct joint CRCI AND anxiety profiles. Differences were evaluated using parametric and nonparametric tests.

RESULTS

Three classes were identified (ie, No CRCI and Low Anxiety [57.3%], Moderate CRCI and Moderate Anxiety [34.5%], and High CRCI and High Anxiety [8.2%]). All of the stress measures showed a dose-response effect (ie, as the CRCI AND anxiety profile worsened, scores for all three types of stress increased). The two highest symptom classes reported higher occurrence rates for six specific stressors (eg, emotional abuse, physical abuse, sexual harassment).

CONCLUSIONS

Findings suggest that higher levels of co-occurring CRCI AND anxiety are associated with some common risk factors, as well as higher levels of stress and lower levels of resilience. Increased knowledge of modifiable risk factors and sources of stress associated with the co-occurrence of these two symptoms will assist clinicians to identify high-risk patients and implement individualized interventions.

Psychometric validation of the Perceived Stress Scale (PSS-10) among family caregivers of people with schizophrenia in China

BACKGROUND

The 10-item Perceived Stress Scale (PSS-10) is a widely used measure of perceived stress that has been validated in various populations, yet with inconsistent results on its factor structure. The present study examines the reliability and validity of the PSS-10 in a population not previously examined: Chinese family caregivers of persons with schizophrenia, with a focus on factor analysis.

METHODS

A sample of 449 family caregivers of persons with schizophrenia was recruited for psychometric testing of the scale. The factor structure of PSS-10 was tested by randomly dividing the sample into two groups for both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The scale was further tested for internal consistency, test-retest reliability, convergent validity, discriminant validity and concurrent validity.

RESULTS

EFA extracted two factors: perceived helplessness with six negative phrasing items and perceived efficacy with four positive phrasing items. CFA confirmed the structure of two factors with satisfactory model fit indices. Convergent validity was supported by high standard regression weight (0.78-0.92), average variance extracted (AVE=0.79-0.81) and composite reliability (0.88-0.94), while discriminant validity was confirmed by higher AVE estimates than the squared interconstruct correlations. The PSS-10 showed good internal consistency and test-retest reliability, with Cronbach's alpha of 0.79 and intraclass correlation coefficient of 0.91, respectively. Concurrent validity was demonstrated by its significant positive correlations with stigma, depression and anxiety, as well as significant negative correlations with social support, family functioning and positive caregiving experiences.

CONCLUSION

The two-factor PSS-10 has good psychometric characteristics assessing the perceived stress of family caregivers of people with schizophrenia. The findings indicate that the PSS-10 can be used to measure perceived stress in future research and practice among caregivers of people with schizophrenia, and potentially, other caregiving samples.

Sleep and Perceived Stress: An Exploratory Mediation Analysis of the Role of Self-Control and Resilience among University Students

BACKGROUND

High levels of stress are frequent in university education, and a lack of sleep has been reported to make students more vulnerable to stress. The mechanisms through which sleep harms students have not been sufficiently clarified; therefore, this study aimed to explore the mediating role of self-control and resilience in the relationship between sleep quality and duration and perceived stress.

METHODS

Of 32 first-year college students, 21 (78%) were women, with a mean age of 18.47 (±0.84). They responded to a self-administered survey that included questions on stress, resilience, and sleep quality and recorded their daily sleep duration using a wristband for six days.

RESULTS

Perceived stress was significantly correlated with resilience (r = -0.63), self-control (r = -0.46), sleep duration (r = -0.35), and lower sleep quality (r = 0.57). Path analysis revealed that self-control and resilience were partially mediated by sleep quality (R2 = 0.62; p < 0.01) and completely mediated by sleep duration (R2 = 0.46; p < 0.01). In both models, self-control had a direct effect on resilience and had a good-fit index.

CONCLUSION

Being resilient seems to play a mediating role in the relationship between sleep and perceived stress; this ability can be favored by self-control, which is directly influenced by sleep.

Validity and reliability of the Sinhalese version of the perceived stress scale questionnaire among Sri Lankans

Introduction

Despite the availability of validated psychometrics tools to assess depression, there has not been any validated and reliable tool established to test perceived stress among Sri Lankans. The objective of this study is to test the validity and reliability of the Sinhalese Version of the Sheldon Cohen Perceived Stress Scale.

Materials and methods

Standard and systematic procedures were adopted to translate the original English version of the Perceived Stress Scale-10 questionnaire into Sinhalese. Consecutive sampling was employed to recruit the Type 2 Diabetes mellitus (T2DM) sample (n = 321), and a convenient sampling was used to recruit the Age and Sex matched Healthy Controls (ASMHC) (n = 101) and the Healthy Community Controls (HCC) groups (n = 75). Cronbach alpha was used to assess internal consistency and reliability was determined using test-retest method utilizing Spearman's correlation coefficient. Sensitivity was evaluated by comparing the mean scores of the Sinhalese Perceived Stress Scale (S-PSS-10) and Sinhalese Patient Health Questionnaire (S-PHQ-9) scores. Post-hoc comparisons were done using Bonferroni's method. Mean scores were compared between the T2DM, ASMHC, and HCC groups using the independent t-test. Explanatory Factor Analysis (EFA) was conducted using the principal component and Varimax rotation while the Confirmatory Factor Analysis (CFA) was performed to assess the goodness-of-fit of the factor structure extracted from the EFA. Concurrent validity was assessed using the Pearson correlation between the S-PSS-10 and Patient Health Questionnaire measured by S-PHQ-9 (p < 0.05).

Results

Cronbach alpha values of the three groups T2DM, ASMHC and HCC were 0.85, 0.81, and 0.79, respectively. Results of the ANOVA test suggested that there was a significant difference in the mean scores between groups (p < 0.00). EFA analysis revealed the existence of two factors with eigenvalues greater than 1.0. The factor loadings for the items ranged from 0.71-0.83. The CFA analysis demonstrated a good model fit for the two-factor model S-PSS-10. The S-PSS-10 significantly correlated with S-PHQ-9, indicating an acceptable concurrent validity.

Conclusion

Findings revealed that the S-PSS-10 questionnaire can be used to screen perceived stress among the majority of the Sri Lankan Sinhalese-speaking population specially with chronic illnesses. Further studies with higher sample sizes across different populations would enhance the validity and reliability of S-PSS-10.

Evaluating the Benefits of a Family Support Program on the Health and Well-Being of Aging Family Caregivers of Adults with Intellectual and Developmental Disabilities

Providing care to a family member with intellectual and developmental disabilities (I/DD) takes a toll on the health of the caregiver and the family, especially as they age. Research shows that peer mediated family support programs can improve caregiver health and well-being. To date, most family support programs have focused on family caregivers of children and youth with I/DD. The purpose of this study was to examine the benefits of participating in the Michigan Older Caregivers of Emerging Adults with Autism and Neurodevelopmental Disabilities (MI-OCEAN) family support program grounded in the Family Quality of Life (FQOL) framework. Specifically, we examined the effect of participation on health care utilization, caregiver well-being, and perceptions of global FQOL for older caregivers of adults with I/DD. Quantitative analysis of data gathered from 82 caregivers (age 50 and older) indicated that study participation was associated with increased use of Medicaid and improved caregiver well-being (reduced burden, stress, depression; increased health satisfaction and FQOL). Future research is needed to examine the long-term impact of the family support programs in improving the health and well-being of older caregivers of adults with I/DD.

Psychometric properties of the perceived stress scale (pss-10) with breast cancer patients

Breast cancer diagnosis is one of the most difficult events that a woman can experience during her life and it usually produces high levels of stress. Global measures of perceived stress are useful for screening and for comparing stress levels between cancer patients and other clinical and nonclinical populations. One such instrument that is widely used is the Perceived Stress Scale (pss-10), but its psychometric properties have scarcely been analysed with breast cancer patients. The aim of this study was to provide validity evidence regarding the use of the 10-item version of the pss-10 as a tool for measuring perceived stress in this context. Participants were 215 Spanish breast cancer patients who completed the PSS-10 and the DASS-21, a measure of affective distress (depression, anxiety, and stress). The internal structure of the PSS-10 was examined through confirmatory factor analysis (CFA), and the reliability of test scores was estimated using McDonald's omega coefficient. Validity evidence based on relationships with other variables was also obtained using correlation analysis. The CFA supported a correlated two-factor structure: perceived helplessness (six negatively worded items) and perceived self-efficacy (four positively worded items). Reliability coefficients for scores on these two factors were 0.87 and 0.73, respectively. Scores on affective distress (DASS-21) were strongly and positively correlated with perceived helplessness and moderately and negatively correlated with perceived self-efficacy. The PSS-10 is an adequate tool for measuring perceived stress in the breast cancer context and it may be useful for identifying women at risk of psychological maladjustment.

Assessment of stress management coaching among Nigerian pre-service history teachers: A randomized controlled study

BACKGROUND

Studies have found that pre-service teachers commonly face stressful circumstances that prevent them from completing their academic tasks effectively. In terms of psychological factors and interventions, pre-service history teachers in Nigeria are the least studied group. The objective of this study was to investigate the effect of stress management coaching among Nigerian pre-service history teachers.

METHODS

The research participants consisted of a randomized sample of 109 pre-service history teachers from Nigerian public higher education institutions (55 pre-service history teachers composed the stress management coaching group while 54 pre-service history teachers composed the waitlist control group). The stress management coaching for the pre-service history teachers was guided by a coaching manual created using the theoretical framework of rational emotive behavior coaching.

RESULTS

Pre-service history teachers who participated in stress management coaching showed significantly reduced stress levels at the post-test and follow-up. There was an interaction effect between group and time on the stress of pre-service history teachers.

CONCLUSION

The study suggests that pre-service history teachers can benefit from a stress management coaching intervention that uses the rational emotive behavior coaching approach. The development of this form of stress management coaching program on a large scale among pre-service history teachers could prove beneficial to their academic and personal success. Studies may be conducted in the future to examine the stress of history teachers in colleges and the efficacy of stress management coaching.

Self-awareness protects working memory in people under chronic stress: An ERP study

Chronic stress impairs working memory (WM), but few studies have explored the protective factors of the impairment. We aimed to investigate the effect of self-awareness on WM processing in people under chronic stress. Participants under chronic stress completed an n-back task after a self-awareness priming paradigm during which electroencephalograms were recorded. The behavioral results showed that participants whose self-awareness was primed reacted faster and more accurately than the controls. Event-related potentials (ERPs) revealed the following (1) P2 was more positive in the self-awareness group than in the controls, indicating that self-awareness enhanced allocation of attention resources at the encoding stage. (2) N2 was attenuated in the self-awareness group compared with the controls, indicating that smaller attention control efforts were required to complete WM tasks adequately after self-awareness priming; and (3) enhanced late positive potential (LPP) was evoked in the self-awareness group compared with the controls, suggesting self-awareness enabled participants to focus attention resources on the information at the maintenance stage. Critically, mediational analyses showed that LPP mediated the relationship between self-awareness and WM response times. This result suggests that the fact that participants whose self-awareness was primed were able to achieve better behavioral performances may be attributed to their mobilization of sustained attention resources at the maintenance stage. In summary, self-awareness exerted a protective effect on WM in those under chronic stress, which may be due to the enhancements in the allocation and mobilization of attention. These results could be used to develop more specific coping strategies for people under chronic stress.

Measuring Productivity, Perceived Stress and Work Engagement of a Nationally Delivered Workplace Step Count Challenge

Workplace step count challenges show promise with regard to increasing physical activity, with walking linked to many positive physical and mental health benefits. Few studies have investigated their effects on work-related outcomes. The aim of this study was to describe (1) the process of collecting work-related outcomes as part of a real-world workplace intervention, the Step Count Challenge, and (2) report step counts and work-related outcomes (productivity, perceived stress and work engagement) during the Step Count Challenge. This pre-post study was conducted as part of a four-week 2018 National Step Count Challenge (SCC) in Scotland, UK. A survey was administered to collect self-reported steps, productivity (HWQ), perceived stress (Cohen Perceived Stress Scale) and work engagement (UWES) on the week prior to the intervention starting (baseline), week 1 and week 4. Process data such as recruitment and response rates were monitored throughout. Of 2042 employees who signed up to the SCC, baseline data were reported for 246 (12% of total; mean age 42.5 years, 83% female). Process data suggest low uptake to the study and poor compliance between surveys time points. Preliminary data suggest positive changes in step counts (3374 steps/day by week 4), stress and productivity. No changes in work engagement were found. The findings highlight the need to integrate research more effectively into real-world interventions, including a true baseline period. The Step Count Challenge may have positive change on some work-related outcomes warranting further investigation into how robust research designs can be delivered without negatively influencing real-world interventions.

Nationwide Study on Stress Perception Among Surgical Residents

OBJECTIVE

Declining number of applicants and high attrition of residents are a dire reality. Surgeons in training are confronted to various stressors which interfere with their performance and may promote burnout. This study measures stress levels of Swiss surgical residents.

METHODS

Swiss surgery residents taking the Surgical Basic Exam from 2016 to 2020 completed the Perceived Stress Scale 10 (PSS). The PSS measures how unpredictable, uncontrollable, and overloaded the respondents evaluate their work life. Scores up to 13 are normal, and scores around 20 are highly pathologic. High subscores of helplessness (PH) and lower subscores of self-efficacy (PSE) indicate distress.

RESULTS

A total of 1694 questionnaires were evaluated (return rate 95.7%). Resident median (m) age was 29 years, 43.5% were female, and 72.7% of the residents were in their first 2 years of training. Residents reported a high PSS (m = 15), a high PH (m = 9), and an ordinary PSE (m = 5). Females reported worse PSS (p < 0.001), PH (p < 0.001), and PSE (p = 0.036). In multivariable analysis, male sex (p < 0.001), aiming at orthopedic (p = 0.017) or visceral surgery (p = 0.004), and French as mother tongue (p = 0.037) predicted lower stress levels, while graduating from a country not adjacent to Switzerland led to higher stress (p = 0.047).

CONCLUSION

Perceived stress levels are high in this prospective and representative cohort study of Swiss surgical residents. Females endured significantly worse stress and helplessness levels than males. These figures are worrisome as they may directly contribute to the declining attractivity of surgical residencies. Detailed sex-specific analysis and correction of stressors are urgently needed to improve residency programs.

Role of Race, Ethnicity, and Immigration in Perceived Stress and Depressive Symptomatology Trends During Pregnancy

Our goal was to examine the role of race, ethnicity, and immigration status on prenatal perceived stress and depressive symptomatology trends across pregnancy in a low-income, minority population of pregnant women in urban Los Angeles. Longitudinal data on 442 Hispanic and Black women were analyzed using mixed effects models with a random intercept for participant were employed to evaluate predictors of higher perceived stress levels and probable depression across pregnancy. Compared to U.S. born Hispanic women, Black women had higher perceived stress (β 2.24; 95% CI 0.41, 4.07) and higher odds of probable depression (OR 2.38; 95% CI 0.95, 5.95) while Hispanic immigrants with greater than 20 years of residency in the U.S. had higher odds of probable depression (OR 2.93; 95% CI 1.10, 7.79). Maternal mental health among Hispanic immigrants with longer U.S. residency and Black race warrants increased attention from public health and clinical agencies.

Perception of stress by different categories of medical personnel during the first wave of the COVID‑19 pandemic in Russia

Relevance. In the context of the pandemic, the current psychological state and the likely delayed deterioration of the mental health of medical personnel, regardless of their professional duties, are of concern. Taking into account the stressful circumstances in which the pandemic has placed all medical workers, assessing the level of perceived stress, as well as identifying risk factors and factors that mitigate stress, is an urgent task, the solution of which will contribute to the effective organization of psychological support for medical personnel.

Methods. The study used a shortened version of the Perceived Stress Scale (PSS10) as the main methodology – a tool designed to study a person's attitude to stressful situations and determine the degree to which life is assessed as stressful and uncontrolled (Cohen et al., 1988). The methodology is widely used by the scientific community, including during the pandemic, and the original English version of the PSS has been translated into many languages and adapted in different countries. The study was conducted through an online survey.

Respondents. The study, conducted in the period from May 9 to June 26, 2020, when there was a steady increase in SARS-CoV 2 virus infections in Russia, involved 1,287 employees of medical institutions in various subjects of the federation (1,079 women and 208 men) aged 19 to 80 years. The sample of the study is represented by doctors, middle and junior medical staff, heads of medical departments and institutions, as well as volunteers.

Results. A high average overall index of perceived stress among employees of medical institutions was revealed. The highest level of stress is observed in the youngest age group (from 19 to 30 years), and with age, the level of stress decreases. There were no differences in the level of stress between male and female health workers in any of the considered stress indicators. Protective factors against increased stress are the presence of children and living with family members or relatives, while the presence of a spouse / partner does not affect the overall indicator of perceived stress. From different categories of medical workers, the index of perceived stress is higher in managers and doctors compared to middle and junior medical personnel. There were no significant differences in the level of stress between the staff working and not working in the "red zone". Differences in the level of stress of medical workers depending on the current situation (the number of infected and dead) in the region of residence were revealed: the level of stress is higher for those specialists who are forced to work in stressful conditions due to the complex epidemiological situation. The relationship between different beliefs about COVID19 and the level of stress is shown: the level of stress is higher in those who take its danger more seriously. In terms of the sources of stress, the most likely predictors are anxiety about exposure to COVID19 at work and the likelihood of infecting loved ones, fear of catching it yourself and getting sick, inability to meet the usual personal needs and economic instability.

Conclusions. Practical interventions, the provision of psychological support and the development of actions to reduce stress for staff during a pandemic, should take into account the role of factors in increasing stress among staff working in specific conditions and focus on the prevailing beliefs and stressors in specific categories of medical factors.

Cross-sectional study to measure household water insecurity and its health outcomes in urban Mexico

OBJECTIVE

To assess the links between structural and household determinants of household water insecurity and test three water insecurity measures against self-reported diarrhoea, dengue fever and perceived stress in the middle-income and low-income urban areas of Torreón, Mexico.

DESIGN

Cross-sectional household survey conducted in two waves (rainy and dry seasons).

PARTICIPANTS

500 households selected via multistage cluster sample in selected communities. Socioeconomic status determined the selection of participant neighbourhoods; five were identified in low socioeconomic status neighbourhoods and five in low-medium socioeconomic status neighbourhoods. We examine how the context of urban water provision is related to a new cross-culturally valid Household Water Insecurity Experiences (HWISE) Scale.

PRIMARY OUTCOME MEASURES

The HWISE Scale, self-reported diarrhoea, dengue fever and the Perceived Stress Scale.

RESULTS

Water system intermittency (adjusted OR (AOR) 3.96, 95% CI 2.40 to 6.54, p<0.001), unpredictability (AOR 2.24, 95% CI 1.34 to 3.74, p=0.002) and the dry season (AOR 3.47, 95% CI 2.18 to 5.52, p<0.001) were structural correlates of the HWISE Scale. This study also found that the HWISE Scale was associated with two health outcomes, self-reported diarrhoea (AOR 1.09, 95% CI 1.03 to 1.15, p=0.002) and perceived stress (β=0.28, SE=0.07, t=4.30, p<0.001), but not self-reported dengue fever (AOR 1.02, 95% CI 0.98 to 1.06). A 3-item hygiene subscore and a 3-item water worry subscore were also both positively associated with self-reported diarrhoea and perceived stress.

CONCLUSION

Short-form screeners of water insecurity may be useful for assessing certain health risks by lay survey workers in settings with limited healthcare resources, particularly in lieu of more expensive microbiological tests that require specialised training and facilities.

Psychological Effects of the COVID-19 Imposed Lockdown on Adults with Attention Deficit/Hyperactivity Disorder: Cross-Sectional Survey Study

BACKGROUND

The psychological effects of the COVID-19 government-imposed lockdown have been studied in several populations. These effects however have not been studied in adult populations with attention deficit/hyperactivity disorder (ADHD).

OBJECTIVE

We wanted to investigate the psychological effects of the COVID-19 imposed lockdown on an adult population with ADHD.

METHODS

We conducted a cross-sectional survey by administering the Patient Health Questionnaire-9, Generalized Anxiety Disorder Scale-7, Brief Adjustment Scale-6, Perceived Stress Scale, and Multidimensional Scale of Perceived Social Support to a pragmatic sample of adults with ADHD.

RESULTS

In total, 24 individuals (male: n=18, 75%; female: n=6, 25%; age: mean 21.75 years, SD 1.85 years) were included in this study. The adults with ADHD we surveyed had significant levels of emotional distress during the COVID-19 pandemic period. However, there was no evidence of significant deterioration to the mental health of our sample during the COVID-19 pandemic.

CONCLUSIONS

When treatment for ADHD is maintained, the effects of the COVID-19 pandemic on the mental health of adults with ADHD are mild. Targeted psychological interventions may be useful in such circumstances.

Cortisol and perceived stress are associated with cytokines levels in patients infected with influenza B virus

Influenza B virus (IBV) causes respiratory infectious disease. Cytokines are important immune mediators during infectious diseases. Cortisol and stress have been related to respiratory infection susceptibility and cytokine regulation. Little is known about systemic cytokines, cortisol, and perceived stress in the early stages of IBV infection. We researched the systemic cytokines and cortisol, as well as the perceived stress and blood cell count in patients infected with IBV. The diagnosis was established using the Luminex xTAG RVP kit and confirmed with qRT-PCR for IBV viral load. The perceived stress was evaluated using the perceived stress scale (PSS-10). Twenty-five plasma cytokines were determined using multiplex immunoassay and cortisol by ELISA. The leukocyte differential count was measured with a standard laboratory protocol. Th1, Th17, and IL-10 cytokines were higher in IBV infected patients (P < 0.05). Leukocytes and neutrophil count negatively correlated with viral load (P < 0.05). Perceived stress had a negative effect on monocyte and systemic cytokines in IBV infected patients (P < 0.05). Cortisol was higher in patients infected with IBV and correlated positively with CCL20 (P < 0.05). Cortisol showed a positive effect on most of the systemic cytokines (P < 0.05). In conclusion, a cytokine pattern was found in IBV infected patients, as well as the possible role of leukocyte counts in the control of IBV. Our results suggest the importance of cortisol and perceived stress on systemic cytokines in patients infected with IBV, but more studies are needed to understand their role in cytokine production in respiratory infectious disease.

International Prevalence and Correlates of Psychological Stress during the Global COVID-19 Pandemic

This study reports perceived stress and associated sociodemographic factors from an international sample of adults, during the COVID-19 pandemic. The Perceived Stress Scale (PSS-10) along with socio-demographic questions were conducted between 8 April 2020 and 11 May 2020. The survey was translated from English into five languages. Recruitment was conducted worldwide using social media. A total of 1685 survey responses were collected across 57 countries with eleven countries (≥30 responses/country) included in the sub-analyses. Overall, the mean PSS-10 score was 19.08 (SD = 7.17), reflecting moderate stress compared to previously reported norms. Female gender was associated with a higher PSS score (3.03, p < 0.05) as well as four-year degree holders (3.29, p < 0.05), while adults over 75 years (-7.46, p < 0.05) had lower PSS scores. Personal care composite score (including hours of sleep, exercise, and meditation) was associated with lower PSS scores (-0.39, p < 0.01). Increases in personal care and changes in work expectations were associated with lower PSS scores (-1.30 (p < 0.05) and -0.38 (p < 0.01), respectively). Lower total PSS scores were reported in Germany (-4.82, p < 0.01) compared to the global response sample mean. This information, collected during the initial period of global mitigation orders, provides insight into potential mental health risks and protective factors during crises.

Psychometric properties of the three versions of the Perceived Stress Scale in Ecuador

BACKGROUND

. The Perceived Stress Scale (PSS) is the most well-known self-report measure to assess perceived psychological stress.

OBJECTIVE

. The objective of the study was to analyze the psychometric properties of three versions of the Perceived Stress Scale (PSS-4, PSS-10 and PSS-14) in Ecuador.

METHODS

. A sample of 7905 university students (46% men and 54% women) from Ecuador were surveyed using all three versions of PSS.

RESULTS

. All three versions showed a satisfactory adjustment with a bifactorial structure based on the item structure rather than underlying dimensions of psychological stress. The reliability was also adequate, with Alpha and Omega coefficients [α = 0.85 and ω = 0.80 for PSS-14; α = 0.85 and ω = 0.87 for PSS-10; α = 0.74 and ω = 0.78 for PSS-4] respectively. Psychological stress scores positively correlated with multiple health indicators such as loneliness, psychological inflexibility, alcohol consumption, and presence of anxiety and depression symptoms, and negatively with resilience.

CONCLUSIONS

. The use of PSS-10 based on its best goodness of fit and PSS-4 as the shortest version are recommended to measure psychological stress, rather than the original PSS-14 version. Psychological stress was significantly higher in women than men.

Psychometric properties of the perceived stress scale in a community sample of Chinese

BACKGROUND

The Perceived Stress Scale (PSS) is a globally used and self-report scale measuring perceived stress. Three versions of PSS (PSS-14, PSS-10 and PSS-4) are available which comprise 14, 10 and 4 items respectively. However, the Chinese version of the PSS has not yet been validated in a large community-based general population. The aims of this study were to evaluate the psychometric properties of the Chinese PSS in a large community-based general population and to compare the appropriateness of the three versions of PSS.

METHODS

A total of 9507 adults with at least a junior high school education and completed PSS-14 from the China Health and Nutrition Survey were involved in this study. The internal consistency reliability of PSS was assessed using Cronbach's alpha coefficient and confirmatory factor analysis was employed to test the construct validity. Modification index was used for model extension and the critical ratio was used for model restriction.

RESULTS

The internal consistency coefficients were satisfactory for PSS-14 and PSS-10, but not for PSS-4. The corresponding Cronbach's alpha were 0.830, 0.754 and 0.473 respectively. A 2-factor structure was confirmed for the PSS-14 and PSS-10, and all items' standardized factor loadings exceeded 0.4 for either negative or positive factors. Given that item 12 loaded on both negative and positive factors for PSS-14 and the goodness of fit for PSS-14 was not acceptable, PSS-13 (PSS-14 excluding item 12) was studied. The construct validities of PSS-13 and PSS-10 were satisfactory, but the goodness of fit for PSS-10 were better than that for PSS-13.

CONCLUSIONS

PSS-13 (PSS-14 excluding item 12) and PSS-10 have satisfactory psychometric properties. PSS-10 are more applicable to measure the perceived stress than PSS-13 in a large community-based general population in China.

Examining the Relationship Between Engagement and Perceived Stress-Related Cognitive Complaints in the Argentinian Working Population

Stress has a negative impact on cognitive functioning and occupational well-being. The aim of this study was to assess the relationship among perceived stress, cognitive complaints and work engagement in public employees from Córdoba, Argentina. In this cross-sectional study, self-report questionnaires were administered to 240 participants. Spanish versions of the following instruments were used: Perceived Stress Scale (PSS), Utrecht Work Engagement Scale (UWES), Memory Failures in Everyday (MFE), Executive Complaint Questionnaire (ECQ). Statistical analysis included ANOVA, path analysis, and multiple logistic regression. Stressed workers showed lower work engagement and more cognitive complaints, even after adjusting for demographic variables. Negative associations were also observed between work engagement and cognitive complaints, suggesting that cognitive difficulties are related to engagement. Given the relation among stress, cognition, and work engagement, it is important to consider these factors to foster workers’ health and work productivity.

Exploring Factors Associated with Physical Activity in Latino Immigrants

Latinos are at increased risk for developing chronic conditions. Regular physical activity (PA) assists in protecting adults from developing type 2 diabetes, excess weight, and heart disease, making PA important for health promotion. This cross-sectional, descriptive investigation was conducted with adults 18 years of age and older in a predominately Latino community. Perceptions of factors which influenced PA were examined. Descriptive statistics and multiple regression analysis were performed. Immigrant Latino males engaged in PA significantly more often than female participants. In Latino participants, those who engaged in walking activities were more likely to engage in both vigorous ( r = .341, p<.005) and moderate PA ( r = .317, p <.001). Self-efficacy and acculturation were significant predictors of PA. Acculturation was associated with physical activity, even after adjusting for perceived stress. Findings highlight the continued importance of self-efficacy to foster health promotion in Latino communities.

Correlation between Sleep Bruxism, Stress, and Depression-A Polysomnographic Study

Background and objectives: Sleep bruxism is a common phenomenon that can affect approximately 13% of adult population. It is estimated that bruxism can be caused by three types of factors: biological, psychological, and exogenous. There are many scientific reports about the coexistence of bruxism, stress, and psychoemotional disorders. The aim of this study is to evaluate the possible correlation between occurrence of sleep bruxism and perceived stress and depressive symptoms. Material and methods: The material of this study consisted of 77 patients of Clinic of Prosthetic Dentistry operating at the Department of Prosthetic Dentistry, Wroclaw Medical University, Poland in which after using guidelines of the American Academy of Sleep Medicine probable sleep bruxism was fund. Patients then underwent video-polysomnography. Exposure to perceived stress was evaluated with Perceived Stress Scale-10 (PSS-10). Occurrence of depressive symptoms was evaluated with Beck’s Depression Inventory (BDI). Results: The analysis showed lack of statistically significant correlation between Bruxism Episodes Index (BEI) and Perceived Stress Scale–10 and Beck’s Depression Inventory scores (p = 0.64, p = 0.65; respectively), also when comparing study group (bruxers) and control group (non-bruxers) (p = 0.88, p = 0.77; respectively). Conclusion: Intensity of sleep bruxism was not statistically significantly correlated with self-reported perceived stress and depression. This issue requires further research.

Acculturation stress and allostatic load among Mexican immigrant women

OBJECTIVES

this case-control study compared levels of stress and allostatic load (AL) among Mexican women in the US ( n =19) and Mexico ( n = 40).

METHOD

measures of stress included the Perceived Stress Scale (PSS) and the Hispanic Women's Social Stressor Scale (HWSSS). A composite measure of 8 indicators of AL (systolic and diastolic blood pressure, body mass index (BMI), waist-to-hip ratio, total cholesterol, glycated hemoglobin (hemoglobin A1C), triglycerides and C-reactive protein) was calculated.

RESULTS

there were no significant group differences in AL between Mexican and Mexican immigrant women ( t = 1.55, p = .126). A principal component factor analysis was conducted on the 8 AL indicators; a 2-factor solution explained 57% of the variance. Group differences in the two AL factors were analyzed using MANOVA. BMI and waist-to-hip ratios were lower, but blood pressure and triglycerides were higher in the US group and were mediated by time in the US. Greater acculturation stress was significantly related to increased waist-to-hip ratio ( r = .57, p = .02).

FINAL REMARKS

findings suggest some measures of AL increased with time in the US, and acculturation stress may be a significant factor.

Assessment of Brain Derived Neurotrophic Factor in hair to study stress responses: A pilot investigation

To study pathogenic stress-effects in health and disease, it is paramount to define easy access parameters for non-invasive analysis of biological change in response to stress. Hair samples successfully provide this access for the study of hypothalamus-pituitary-adrenal axis (HPA) changes. In this study, we assess the hair expression and corresponding epigenetic changes of a neurotrophin essential for autonomic nervous system function and mental health: brain derived neurotrophic factor (BDNF). In three independent studies in healthy academic volunteers (study I: German students, N=36; study II, German academic population sample, N=28; study III: Mexican students, N=115), BDNF protein expression or BDNF gene (BDNF) histone acetylation was determined. Simultaneously, mental distress and distress-associated somatic complaints were assessed by self-report. In study I, we found a negative correlation between hair-BDNF protein level and hair-cortisol as well as between hair-BDNF and somatic complaints, while hair-cortisol correlated positively with mental distress. In study II, we found a negative correlation between H4 histone acetylation at the BDNF gene P4-promoter and somatic complaints. Regression analysis confirmed confounder stability of associations in both studies. In study III, we confirmed study I and found lower hair-BDNF protein level in volunteers with high somatic complaints, who also reported higher mental distress during the end of term exams. The results indicate that BDNF protein levels can be detected in clipped hair and are associated with somatic complaints and stress in life. In addition, we concluded that plucked hair can provide material for the study of epigenetic changes in stress-affected tissues. These tools can prove valuable for future studies on distress, both under experimental and field conditions.

The German Version of the Perceived Stress Scale (PSS-10): Evaluation of Dimensionality, Validity, and Measurement Invariance With Exploratory and Confirmatory Bifactor Modeling

The Perceived Stress Scale (PSS) is a popular instrument for measuring the degree to which individuals appraise situations in their lives as excessively uncontrollable and overloaded. Despite its widespread use (e.g., for evaluating intervention effects in stress management studies), there is still no agreement on its factor structure. Hence, the aim of the present study was to examine the dimensionality, measurement invariance (i.e., across gender, samples, and time), reliability, and validity of the PSS. Data from 11,939 German adults (73% women) were used to establish an exploratory bifactor model for the PSS with one general and two specific factors and to cross-validate this model in a confirmatory bifactor model. The model displayed strong measurement invariance across gender and was replicated in Study 2 in data derived from six randomized controlled trials investigating a web-based stress management training. In Study 2 (overall N = 1,862), we found strong temporal invariance. Also, our analyses of concurrent and predictive validity showed associations with depressive symptoms, anxiety, and insomnia severity for the three latent PSS factors. These results show the implications of the bifactor structure of the PSS that might be of consequence in empirical research.

Income is an independent risk factor for worse asthma outcomes

BACKGROUND

Socioeconomic status (SES) is associated with asthma morbidity in observational studies, but the factors underlying this association are uncertain.

OBJECTIVE

We investigated whether 3 SES correlates-low income, low education, and high perceived stress-were independent risk factors for treatment failure and asthma exacerbations in the context of a randomized controlled trial.

METHODS

The effect of low SES (household income of <$50,000/y and household educational level of less than a Bachelor's degree) and high perceived stress (defined as a score of >20 on a perceived stress scale) on asthma morbidity was analyzed in 381 participants by using Poisson regression models. The primary outcome was treatment failure (defined in the trial protocol as a significant clinical or airflow deterioration), and the secondary outcome was asthma exacerbations requiring systemic corticosteroids.

RESULTS

Fifty-four percent of participants had a low income, 40% had a low educational level, and 17% had high perceived stress levels. Even after adjusting for race and other important confounders, participants with lower income had higher rates of both treatment failures (rate ratio, 1.6; 95% CI, 1.1-2.3; P = .03) and exacerbations (rate ratio, 1.9; 95% CI, 1.1-3.3; P = .02). Adherence with inhaled corticosteroids was similarly high for both income categories. Education and perceived stress were not significantly associated with either outcome.

CONCLUSIONS

In the context of a randomized controlled trial, participants with lower income were more likely to experience adverse asthma outcomes independent of education, perceived stress, race, and medication adherence.

Exercise as a Stress Coping Mechanism in a Pharmacy Student Population

Objective. To assess the coping mechanisms used by pharmacy students and their relationship to perceived stress. Methods. Data were gathered utilizing the Perceived Stress Scale (PSS10) and Brief COPE with the additional coping mechanisms of exercise and use of prescribed medications. Results. A survey that was sent to 368 students had an 81% response rate. Perceived stress was significantly higher than standard populations, but consistent with other pharmacy student populations. The most frequently reported coping mechanisms were the adaptive strategies of active coping, acceptance and planning. Maladaptive strategies of behavioral disengagement, venting and self-blame were significantly associated with higher perceived stress scores and the new addition of an exercise coping mechanism significantly associated with lower perceived stress scores. Use of prescribed medications was not significantly associated with perceived stress levels. Conclusion. Inclusion of exercise as a coping mechanism may be beneficial in similar populations.

Factor structure of the Perceived Stress Scale-10 (PSS) across English and Spanish language responders in the HCHS/SOL Sociocultural Ancillary Study

Despite widespread use, psychometric investigation of the original English and translated Spanish versions of the 10-item Perceived Stress Scale (PSS; Cohen, Kamarck, & Mermelstein, 1983) has been limited among the U.S. Hispanic/Latino population. The present study examined the factor structure, factorial invariance, and reliability and validity of PSS scores from English and Spanish versions using data from 5,176 Hispanics/Latinos who participated in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study. The total sample and language multigroup confirmatory factor analyses supported a bifactor model with all 10 PSS items loading on a general perceived stress factor, and the 4 reverse-worded items also loading on a reverse-worded factor. Internal consistency ranged from .68 to .78, and it was indicated that reliable variance exists beyond the general perceived stress factor. The model displayed configural, metric, scalar, and residual invariance across language groups. Convergent validity analyses indicated that both the general perceived stress factor and the reverse-worded factor were related to scores of depression, anxiety, and anger in the expected directions. The reverse-worded factor added to the validity of the PSS beyond the general perceived stress factor. The total computed score of the PSS can be recommended for use with Hispanics/Latinos in the United States that complete the measure in English or Spanish and the reverse-worded factor can enhance prediction.

Longitudinal and Immediate Effect of Kundalini Yoga on Salivary Levels of Cortisol and Activity of Alpha-Amylase and Its Effect on Perceived Stress

Context:

Stress is defined as an alteration of an organism's balance in response to a demand perceived from the environment. Diverse methods exist to evaluate physiological response. A noninvasive method is salivary measurement of cortisol and alpha-amylase. A growing body of evidence suggests that the regular practice of Yoga would be an effective treatment for stress.

Aims:

To determine the Kundalini Yoga (KY) effect, immediate and after 3 months of regular practice, on the perception of psychological stress and the salivary levels of cortisol and alpha-amylase activity.

Settings and Design:

To determine the psychological perceived stress, levels of cortisol and alpha-amylase activity in saliva, and compare between the participants to KY classes performed for 3 months and a group that does not practice any type of yoga.

Subjects and Methods:

The total sample consisted of 26 people between 18 and 45-year-old; 13 taking part in KY classes given at the Faculty of Dentistry, University of Chile and 13 controls. Salivary samples were collected, enzyme-linked immunosorbent assay was performed to quantify cortisol and kinetic reaction test was made to determine alpha-amylase activity. Perceived Stress Scale was applied at the beginning and at the end of the intervention.

Statistical Analysis Used:

Statistical analysis was applied using Stata v11.1 software. Shapiro–Wilk test was used to determine data distribution. The paired analysis was fulfilled by t-test or Wilcoxon signed-rank test. T-test or Mann–Whitney's test was applied to compare longitudinal data. A statistical significance was considered when P < 0.05.

Results:

KY practice had an immediate effect on salivary cortisol. The activity of alpha-amylase did not show significant changes. A significant decrease of perceived stress in the study group was found.

Conclusions:

KY practice shows an immediate effect on salivary cortisol levels and on perceived stress after 3 months of practice.
