RESUMEN

The current study aimed to assess the psychometric properties of the Spanish language version of the 14-item Perceived Stress Scale (PSS-S) in a population of pregnant women who speak Spanish in Peru using item response theory (IRT). Our study consisted of 5,435 pregnant women who participated in the Pregnancy Outcomes Maternal and Infant Study (PrOMIS) cohort in Peru. Exploratory and confirmatory factor analyses were conducted to determine dimensionality of the scale in this population, and item response theory was conducted to determine the applicability of the PSS. The PSS consisted of a 2-factor questionnaire measuring perceived stress and coping capacity accounting for 77% of variability. The IRT analysis showed differences in item difficulty and discrimination. Item difficulty represents the level of the latent construct where 50% of respondents endorse a particular response, and item discrimination determines the rate of change of the probability of endorsing an item for differing ability levels. For the first factor, perceived stress, item 12 was the least difficult and item 2 was the most difficult. For the second factor, coping capacity, item 9 was the least difficult and item 6 was the most difficult. The Spanish version of the 14-item PSS can be a useful assessment tool for perceived stress, but more IRT should be done to delve further into the psychometric properties of the questionnaire to inform clinicians and policy makers more appropriately.

RESUMEN

BACKGROUND: The Perceived Stress Scale (PSS) is a widely used measure designed to assess perceptions of recent stress. However, it is unclear to what extent the construct assessed by the PSS represents factors that are stable versus variable within individuals, and how these components might vary over time. PURPOSE: Determine the degree to which variability in repeated PSS assessments is attributable to between-person versus within-person variance in two different studies and populations. METHODS: Secondary analyses utilized data from two studies with up to 13 PSS assessments: An observational study of 127 patients with heart failure followed over 39 months (Study 1), and an experimental study of 73 younger, healthy adults followed over 12 months (Study 2). Multilevel linear mixed modeling was used to estimate sources of variance in the PSS total and subscale scores across assessments. RESULTS: Between-person variance accounted for a large proportion of the total variance in PSS total scores in Study 1 (42.3%) and Study 2 (51.1%); within-person variance comprised the remainder. Between-person variance was higher for shorter assessment periods (e.g., 1 week), and was comparable when examining only the first 12 months of assessments in each study (52.9% vs. 51.1%). CONCLUSIONS: Within two samples differing in age and health status, between-person variance accounted for approximately half of the total variation in PSS scores over time. While within-person variance was observed, the construct assessed by the PSS may substantially reflect a more stable characteristic of how an individual perceives stressful life circumstances than previously appreciated.


The Perceived Stress Scale (PSS) is a widely used questionnaire designed to assess how an individual perceives recent stress in their life. It is unclear, however, the degree to which the PSS is measuring factors that are consistent within individuals versus those that fluctuate, and how these components might change when the PSS is administered repeatedly over time. To address this knowledge gap, data from two studies were used­a study of 137 patients with heart failure followed for 39 months and a study of 73 younger, healthy adults followed for 12 months. In each, participants completed up to 13 PSS assessments, with 2,880 total PSS assessments completed across the studies. Multilevel linear mixed modeling was used to examine sources of score variance across assessments. Between-person variance (i.e., score variability that is relatively stable over time but differs between individuals) accounted for approximately half of the total variation in PSS scores over time, and was higher over shorter assessment periods. While within-person variance was observed (i.e., score variability that fluctuates within the same individual over time), these results suggest that the PSS may assess a substantially more stable characteristic of how an individual perceives stressful life circumstances than previously appreciated.

RESUMEN

BACKGROUND: To develop the modified 4-item version of Perceived Stress Scale (PSS) with a better reliability and validity than the 4-item version of PSS (PSS-4) in evaluating psychological stress in patients with functional dyspepsia (FD). The present study also aimed to explore the correlation between dyspepsia symptoms severity (DSS), anxiety, depression, somatization, quality of life (QoL), and psychological stress assessed by two approaches in FD. METHODS: A total of 389 FD patients who met the Roman IV criteria completed the 10-item version of the PSS (PSS-10), and 4/10 items were selected by five methods, such as Cronbach's coefficient, exploratory factor analysis (EFA), correlation coefficient, discrete degree, and item analysis, to develop the modified PSS-4. The reliability and validity of the modified PSS-4 and the PSS-4 were compared by internal consistency, EFA, and confirmatory factor analysis (CFA). The correlation between psychological stress assessed by two approaches and DSS, anxiety, depression, somatization, and QoL was explored by Pearson's correlation coefficient and multiple linear regression analysis. RESULTS: Cronbach's α coefficient of the modified PSS-4 and the PSS-4 was 0.855 and 0.848, respectively, and a common factor was extracted. The cumulative contribution rate of one factor to the overall variance for the modified PSS-4 and the PSS-4 was 70.194% and 68.698%, respectively. The model used for the modified PSS-4 showed that the values of the goodness-of-fit index (GFI) and the adjusted GFI (AGFI) were 0.987 and 0.933, respectively, indicating that the model fitted well. Psychological stress was correlated to DSS, anxiety, depression, somatization, and QoL as assessed by the modified PSS-4 and PSS-4. Multiple linear regression analysis revealed that psychological stress was correlated to somatization, as assessed by the modified PSS-4 (ß = 0.251, P < 0.001) and PSS-4 (ß = 0.247, P < 0.001). Psychological stress, DSS, and somatization were correlated to QoL, as assessed by the modified PSS-4 (ß = 0.173, P < 0.001) and the PSS-4 (ß = 0.167, P < 0.001). CONCLUSIONS: The modified PSS-4 showed better reliability and validity, and psychological stress had a greater effect on the somatization and QoL of FD patients assessed by the modified PSS-4 than PSS-4. These findings were helpful for further investigation of the clinical application of the modified PSS-4 in FD.

RESUMEN

BACKGROUND: Stress reflects physical and psychological reactions to imposing demands and is often measured using self-reports. A widely-used instrument is the Perceived Stress Scale (PSS), intended to capture more general aspects of stress. A Swedish translation of the PSS is available but has not previously been examined using modern test theory approaches. The aim of the current study is to apply Rasch analysis to further the understanding of the PSS' measurement properties, and, in turn, improve its utility in different settings. METHODS: Data from 793 university students was used to investigate the dimensionality of different version of the PSS (14, 10, and 4 items) as well as potential response patterns among the participants. RESULTS: The current study demonstrates that the PSS-14 has two separate factors, divided between negatively worded items (perceived stress) and positively worded items (perceived [lack of] control), although with only the negative subscale exhibiting good reliability. Response patterns were analyzed using Differential Item Functioning, which did not find an influence of gender on any of the items, but for age regarding the positive subscale (items 6 and 9). The PSS-10 also demonstrated adequate reliability for the negative subscale, but the PSS-4 was not deemed suitable as a unidimensional scale. CONCLUSIONS: Based on the results, none of the versions of the PSS should be used by sum-scoring all of the items. Only the negative items from the PSS-14 or PSS-10 can be used as unidimensional scales to measure general aspects of stress. As for different response patterns, gender may nevertheless be important to consider, as prior research has found differences on several items. Meanwhile, content validity is discussed, questioning the relevance of anger and being upset when measuring more general aspects of stress. Finally, a table to convert the PSS-7 (i.e., negative items) ordinal sum scores to interval level scores is provided.

RESUMEN

AIM: The Pittsburgh Sleep Quality Index is a widely used measure of sleep quality. The validity and reliability of the Danish version of the instrument has not yet been established. The aim of this study is to establish the internal consistency, test-retest reliability and convergent validity of the Danish version of the Pittsburgh Sleep Quality Index in adolescents. METHODS: Data were collected from 719 students from 17 different upper secondary schools. The sample consisted of 55% women, and the mean age of the sample was 17.87 (2.52) years. Data was collected on two occasions approximately 6 weeks apart using online surveys. Apart from the Pittsburgh Sleep Quality Index, the students also completed the five-item World Health Organization Well-being Index and the 10-item Perceived Stress Scale. For internal consistency the Cronbach's alpha was calculated, for test-retest reliability the interclass correlation coefficient was computed, and for validity the Pearson's correlation was calculated. RESULTS: The mean global Pittsburgh Sleep Quality Index score among Danish adolescents was 5.86 (3.13). The internal consistency for the Pittsburgh Sleep Quality Index was satisfactory with a Cronbach's alpha of 0.72. Test-retest reliability was adequate with an interclass correlation coefficient of 0.68. Finally, the Pittsburgh Sleep Quality Index showed large positive correlation with the 10-item Perceived Stress Scale (0.55) and a large negative correlation with the five-item World Health Organization Well-being Index (-0.59). CONCLUSIONS: The Danish version of the Pittsburgh Sleep Quality Index showed adequate reliability and validity among Danish adolescents.

RESUMEN

BACKGROUND: Nurses bear a lot of stressors at work. The 10-item Perceived Stress Scale (PSS-10) is a widely used self-reported scale for measuring the global perception of stress. However, there is a lack of use of the PSS-10 in Chinese nurses. This study aimed to test the psychometric properties of the PSS-10 among Chinese nurses. METHODS: A total of 708 Chinese nurses completed the PSS-10, the Big Five Inventory (BFI), and the Depression Anxiety and Stress Scale (DASS). Confirmatory factor analysis (CFA) tested the factor structure of the PSS-10. Cronbach's α and test-retest correlation examined the scale reliability. Pearson correlation and hierarchical regression analyses tested the convergent, discriminant and criterion validity of the PSS-10. RESULTS: CFA revealed that a two-factor model fits the structure of the PSS-10 in Chinese nurses (χ2/df = 6.25, p < 0.001; comparative fit index [CFI] = 0.94, non-normal fit index [NNFI] = 0.92, Tucker-Lewis index [TLI] = 0.91, root mean square error of approximation [RMSEA] = 0.08, standardized root mean square residual [SRMR] = 0.05). The scale demonstrated adequate internal consistency (α = 0.86) and test-retest reliability (r = 0.66, p < 0.001), satisfactory convergent and discriminant validity with relations to Big Five personalities, as well as good criterion validity such that the PSS-10 score could explain incremental variance in predicting anxiety, depression and stress. CONCLUSIONS: Our findings suggest that PSS-10 is a reliable and valid measure of perceived stress among Chinese nurses and can be used in future research and practice on stress management and coping in Chinese nurses.

RESUMEN

Objective: To determine the correlation between levels of stress with level of empathy in all five years of undergraduate medical students of a private medical college in Pakistan. Methods: This descriptive correlation study was conducted at Al Tibri Medical College, Karachi from 15th June to 14th November 2021. Of the 500 students in the medical school, 408 participants filled out the questionnaires through online Google Forms. The student's version of the Jefferson Scale of Empathy (JSE-S) estimated the self-reported student's empathy levels. At the same time, Perceived Stress Scale (PSS) was utilized to assess the student's levels of stress. Data was analyzed using SPSS version 22.0 and correlation between empathy and perceived stress was calculated by Pearson's coefficient. A p-value <.05 was considered statistically significant. Results: Out of 408 participants, there were 217(53.2%) males, and 191(46.8%) females. The overall mean JSE-S score was 94.60±11.85, and the mean PSS score was 20.20 ±5.70. Empathy scores improved over the basic sciences years and then significantly decreased in the clinical years of medical college with a significant p-value of .019. The highest stress was present in third year medical students with a p-value of <.001. No statistically significant difference was present between empathy and stress levels (r = 0.04, p = .40). Conclusions: The study showed no statistically significant correlation between empathy and stress. Future research is needed to investigate other main factors for the decline in empathy among medical students.

RESUMEN

Chronic rhinitis and rhinosinusitis (CR and CRS) can lead to impairment of the health-related quality of life (HRQL) with higher psychological perceived distress, resulting in disease worsening and poor treatment outcomes. W aimed to evaluate the potential association between disease severity and HRQL impairment with the perceived acute psychological distress in newly diagnosed CR/CRS patients. This single-center cross-sectional study included otherwise healthy consecutive adults with newly diagnosed CR/CRS (European position paper on rhinosinusitis and nasal polyp criteria and International Consensus Statement on Allergy and Rhinology - Allergic Rhinitis criteria or non-allergic rhinitis), who were evaluated for CR/CRS symptom severity and HRQL (Sino Nasal Outcome Test 22 [SNOT-22], visual analog scale [VAS]) and acute perceived distress (Perceived Stress Scale [PSS]). Principal component analysis (SNOT-22 items, VAS) identified 6 components as CR/CRS severity indicators, i.e,, poor sleep, wakes-up tired, nasopharynx, obstruction, torment and rhinorrhea, which were evaluated for association with PSS score. Of the 63 included patients (20 men, age median 38, range 19-75 years), 27 suffered from CR and 36 from CRS. Upon adjustment for age and sex, higher total SNOT-22 (geometric means ratio [GMR]=1.04, 95% CI 1.01-1.06), higher "torment" (GMR=1.13, 1.04-1.24), higher "poor sleep" (GMR=1.11, 1.02-1.21) and higher "wakes-up tired" (GMR=1.11, 1.01-1.21) scores were each associated with a higher PSS score, overall and consistently in CR and CRS patients. In conclusion, more severe CR/CRS is associated with greater perceived psychological distress already at earlier stages of the disease. Paying attention to patient level of distress and anxiety over time may enable better understanding of the connection between exacerbations, symptom severity and psychological burden of the disease.

RESUMEN

Background: Stress amidst the COVID-19 pandemic is becoming more prevalent. This paper aimed to describe the validation process of the Malay Perceived Stress Scale modified for COVID-19 (PSS-10-C) amongst Malaysian youths. Methods: The cross-sectional validation study design was employed in this study. In Phase I, the scale was translated into Malay by using the forward-backward method. In Phase 2, principal axis factoring and confirmatory factor analysis were conducted in Study 1 (n = 267) and Study 2 (n = 324), respectively. Results: A two-factor solution, comprising 'distress' and 'coping' domains was derived (cumulative variance = 65.2%) in Phase 2. Concurrent validity evaluated via the Beck Hopelessness Scale revealed a moderate positive correlation (0.528). In Study 2 (n = 324), the confirmatory factor analysis showed that the two-factor model achieved acceptable model fit indices, including χ2/df ratio = 2.57; root mean square error of approximation (RMSEA) = 0.07; 95% CI = 0.05, 0.09; Tucker-Lewis Index (TLI) = 0.95 and Normed Fit Index (NFI) = 0.94. The Cronbach's alpha scale score was 0.855 for the study samples. Conclusion: The Malay PSS-10-C is a valid and reliable scale to be used amongst Malaysian youths.

RESUMEN

Only a few studies have investigated the association between psychological stress and the healthfulness of plant-based diets while accounting for variances in age groups and regions. In light of this, this study aimed to identify the food groups that contribute the most to the relationship between the healthfulness of plant-based diets and psychological stress in female students in Saudi Arabia. This cross-sectional study, which included 401 female college students aged 19-35 years, collected data on blood, anthropometric indices, the perceived stress scale-10 (PSS-10) and diet using the Saudi food frequency questionnaire. An overall plant-based diet index (PDI), healthy PDI, and an unhealthy PDI (uPDI) were defined. Multiple linear regression analyses were applied to examine the associations between PSS-10 and PDI and hPDI and uPDI. No associations between the PSS-10 score and the overall PDI or uPDI scores were found; however, a six-point higher hPDI score was associated with a 0·16-point lower PSS-10 score (95 % CI, -0·24, -0·08) after controlling for lifestyle factors. Moreover, adjustments for healthy food groups, including vegetables and fruits, attenuated the association between the hPDI and PSS-10. In conclusion, healthy plant-based diets are associated with lower psychological stress in young Saudi women. This finding highlights the importance, especially for female students, of following diets that are not only plant-based but are also healthy and rich in fruits and vegetables.

RESUMEN

PURPOSE: Behavioral interventions have been used with breast cancer survivors (BCS) in cancer pain management and post-treatment quality of life (QOL) studies. We studied the effects of an anti-inflammatory dietary intervention on QOL in BCS. METHODS: One hundred fifty-three overweight and obese (body mass index [BMI] ≥ 25 kg/m2), early stage (0-III), English-speaking BCS who had completed all cancer treatment 2 or more months prior to enrollment were recruited into a two-arm randomized controlled trial with a 2 (group) by 3 (time) repeated measures design. Intervention components included six monthly food-preparation workshops and twelve motivational interviewing telephone calls. Endpoints included the Perceived Stress Scale (PSS), the Functional Assessment of Cancer Therapy-General (FACT-G) and Breast Cancer (FACT-B), and the Center for Epidemiologic Studies Depression Scale (CES-D). Repeated measures analysis using PROC MIXED in SAS version 9.4 was used. RESULTS: On repeated measures analysis (intent to treat), there were no differences between groups on any of the QOL outcomes except the PSS total scores. These were significantly different in the intervention group (IG; n = 76) compared to control group (CG; n = 77), showing a main effect of assignment but no effect of time and no interaction effects. CONCLUSION: There was an impact on QOL as measured by the PSS between groups. The intervention reduced perceived stress at 6-month follow-up, but the effects dissipated by 12 months. Sources and stress and stress reduction should be a focus of future studies. Future research should also identify appropriate QOL measures that are sensitive to changes brought about by behavioral interventions.

RESUMEN

BACKGROUND: Perceived stress scale (PSS) is the most widely used tool for assessing stressful life events and its management. However, its validity and Reliability in Ethiopian Amharic language is not assessed. OBJECTIVE: To translate the perceived stress scale (version PSS-10) and assess its validity among Defense University students in Bishoftu, Ethiopia. METHOD: From March to May 2020, an anonymous, self-managed questionnaire was used to collect the data on 758 undergraduate students of Defense University in Bishoftu, Ethiopia. Exploratory and Confirmatory factor analyses were employed to assess the factor structure and construct validity of Amharic version of the PSS-10. Composite reliability coefficient and Item total correlation were calculated to assess the internal consistency of Amharic version of the PSS-10. RESULT: Exploratory factor analysis resulted in a two-dimensional PSS-10 with Eigenvalues of 3.4 and 1.6, which explained 50.7% of the variance. Confirmatory factor analysis indicates a good model fit of the two correlated factors (Comparative fit index (CFI) = 0.96 with root mean square error of approximation (RMSEA) = 0.04[0.03-0.06] and standardize root mean residual (SRMR) = 0.040). The internal consistency of PSS-10 and the Negative factor were in acceptable range, whereas the Positive factor was marginally acceptable (0.77, 0.78, and 0.68) respectively. CONCLUSION: The Amharic translated version of PSS-10 was found to be a valid and reliable instrument to measure the perceived stress level among university students.

RESUMEN

Over the last decade, virtual reality (VR) has become an increasingly accessible commodity. Head-mounted display (HMD) immersive technologies allow researchers to simulate experimental scenarios that would be unfeasible or risky in real life. An example is extreme heights exposure simulations, which can be utilized in research on stress system mobilization. Until recently, electroencephalography (EEG)-related research was focused on mental stress prompted by social or mathematical challenges, with only a few studies employing HMD VR techniques to induce stress. In this study, we combine a state-of-the-art EEG wearable device and an electrocardiography (ECG) sensor with a VR headset to provoke stress in a high-altitude scenarios while monitoring EEG and ECG biomarkers in real time. A robust pipeline for signal clearing is implemented to preprocess the noise-infiltrated (due to movement) EEG data. Statistical and correlation analysis is employed to explore the relationship between these biomarkers with stress. The participant pool is divided into two groups based on their heart rate increase, where statistically important EEG biomarker differences emerged between them. Finally, the occipital-region band power changes and occipital asymmetry alterations were found to be associated with height-related stress and brain activation in beta and gamma bands, which correlates with the results of the self-reported Perceived Stress Scale questionnaire.

RESUMEN

BACKGROUND: The association of dietary patterns and metabolic syndrome with the severity of coronary artery disease (CAD) is little known. AIM: This study aimed to explore the relationship between major dietary patterns and the severity of CAD among newly discovered patients by using structural equation modeling (SEM). METHODS: In this cross-sectional study, we included 423 newly diagnosed patients with CAD, aged 35-65 years, who underwent coronary angiography. The severity of CAD was assessed by the Gensini score. All patients were tested by using a semi-quantitative food frequency questionnaire, international physical activity questionnaire, perceived stress scale, lipid profile, fasting blood glucose, and anthropometric and blood pressure measurements. Statistical analysis was performed using SPSS and AMOS version 24. RESULTS: Two dietary patterns (DPs) were identified by principal components analysis and labeled as "unhealthy DP" and "healthy DP". The results of SEM analysis showed that the unhealthy DP has a significant positive direct association with the severity of CAD (ß=0.304, p<0.001), which is indirectly mediated by the presence of metabolic syndrome (ß=0.021, p=0.021), adjusted for age and perceived stress scale. However, healthy DP has a significant negative direct association with the Gensini score (ß=-0.213, p<0.001), and an indirect association through negative metabolic syndrome (ß=-0.019, p=0.022), controlled for gender, physical activity, and perceived stress scale. CONCLUSIONS: The severity of CAD was directly associated with the unhealthy DP and indirectly mediated by the presence of the metabolic syndrome, while a healthy DP had a direct inverse association with CAD severity and indirectly mediated by the absence of metabolic syndrome.

RESUMEN

This study aimed to investigate the association of perceived stress and salivary cortisol levels with the snack and fast-food dietary pattern in a sample of women shift workers. We conducted a cross-sectional study of 539 women aged 18-53 years working in the production line of a poultry processing plant. Stress was assessed with the 10-item Perceived Stress Scale (PSS-10) and by salivary cortisol levels (immediately after waking and upon returning home from work). Dietary patterns were identified by principal component analysis. We used linear and Poisson regression models to assess multivariable-adjusted associations of perceived stress and salivary cortisol levels with the snack and fast-food dietary pattern. After adjustments, women with higher PSS-10 scores had a 28% higher probability (95% confidence interval, 1.04-1.56) of consuming snacks/fast food. Mean (SD) waking cortisol levels were inversely associated with quartiles of the dietary pattern: Q1, 6.63 (0.43) nmol/L; Q2, 6.00 (0.38) nmol/L; Q3, 5.62 (0.40) nmol/L; and Q4, 5.29 (0.35) nmol/L (p = 0.019). Perceived stress was not associated with salivary cortisol levels. The work shift was not associated with perceived stress or cortisol levels. This study demonstrated an association of psychological and physiological measures of stress with a dietary pattern characterized by high intakes of hyper-palatable, energy-dense, ready-to-eat foods among women shift workers.

RESUMEN

INTRODUCTION/AIMS: In this study, we examined the social and health impacts of the coronavirus disease 2019 (COVID-19) pandemic and social guidelines on people with muscular dystrophies. METHODS: A prospective de-identified electronic survey was distributed to adults with self-reported facioscapulohumeral muscular dystrophy (FSHD), myotonic dystrophy (DM), and limb-girdle muscular dystrophy (LGMD) enrolled in national registries or with patient advocacy groups. The COVID-19 Impact Survey was developed by muscular dystrophy experts in association with patient collaborators and advocacy groups. The Perceived Stress Scale was used to measure perceived stress. RESULTS: Respondents (n = 774: 56% FSHD; 35% DM, and 9% LGMD) were mostly women and middle-aged (range 19-87 y). Rates of COVID-19 infections were low (<1%), compliance with local social distancing guidelines and policies high (98%). Major challenges reported during the pandemic included: obtaining treatment (40%), managing stress (37%), social distancing (36%), and obtaining essentials (34%). The majority reported a slight worsening in their disease state. Respondents reported moderate stress levels (stress score = 15.4; range = 0-35), with higher stress levels reported by women and those under age 30 y. Three-quarters of participants who participated in telemedicine visits were satisfied with the encounters; however, most reported a preference for in-person visits. DISCUSSION: People with muscular dystrophy reported moderate stress and challenges during the COVID-19 pandemic. Interventions such as exercise and stress-coping strategies, including strategies specific to women or individuals <30 y, may be important. Further investigation is needed into the role of telemedicine in the care of individuals with muscular dystrophy.

RESUMEN

PURPOSE: Few studies have addressed the sleep disturbances of healthcare workers during crisis events of public health. This study aimed to examine the sleep quality of frontline healthcare workers (FLHCW) in Bahrain during the COVID-19 pandemic, and compare it with the sleep quality of non-frontline healthcare workers (NFLHCW). METHODS: Healthcare workers (n = 280) from multiple facilities belonging to the Ministry of Health, Bahrain, were invited to participate in this cross-sectional study. An online questionnaire, including socio-demographics, the Pittsburgh Sleep Quality Index (PSQI), and the Perceived Stress Scale (PSS), was used to evaluate sleep disturbances and stress levels of healthcare workers. Poor sleep quality was defined as PSQI ≥ 5 and moderate-severe stress as PSS ≥ 14. Descriptive statistics were used to compare the scores of FLHCW and NFLHCW. Univariate and multivariate binary logistic regressions were used to identify predictors of poor sleep quality, moderate-severe stress, and the combined problem of poor sleep quality and moderate-severe stress. RESULTS: A total of 257 participants (129 FLHCW and 128 NFLHCW) provided usable responses. The overall PSQI and PSS scores were 7.0 ± 3.3 and 20.2 ± 7.1, respectively. The FLHCW scored higher in the PSQI and PSS compared with the NFLHCW; however, the differences in the PSQI and PSS scores were not statistically significant. For the FLHCW, 75% were poor sleepers, 85% had moderate-severe stress, and 61% had both poor sleep quality and moderate-severe stress. For the NFLHCW, 76% were poor sleepers, 84% had moderate-severe stress, and 62% had both poor sleep quality and moderate-severe stress. Female sex and professional background were the predictors of poor sleep quality and stress. CONCLUSIONS: Poor sleep quality and stress are common during the COVID-19 crisis. Approximately, 60% of both FLHCW and NFLHCW have poor sleep quality combined with moderate-severe stress.

RESUMEN

BACKGROUND: High levels of perceived stress have a negative bearing on health and well-being, and stress is a major public health issue. According to the Stress Process Model, stressors are socially patterned and combine to produce strain. Despite this, most studies on stress have focused on work-related stressors leaving non-work determinants under-investigated. The aim of the present study was to determine the relative importance of work-related and non-work-related stressors and perceived social support for the overall perceived stress level. METHODS: Self-reported data were drawn from the 2017 population-based health survey "How are you?" conducted in the Central Denmark Region (N = 32,417). Data were linked with data drawn from national administrative registers. Work- and non-work-related stressors assessed included major life events, chronic stressors and daily hassles. Perceived social support was assessed using a single question. Overall perceived stress was assessed by the 10-item Perceived Stress Scale. We conducted dominance analyses based on a multiple linear regression model to determine the most important explanatory variables of overall perceived stress. Analyses were weighted and adjusted. RESULTS: Work- and non-work-related stressors along with perceived social support explained 42.5% of the total variance (R2) in overall perceived stress. The most important explanatory variables were disease, perceived social support and work situation. The stratified analyses produced slightly varying results ("dominance profiles") of perceived stress between subgroups. Work situation was the most important explanatory variable in the employed group. However, adding non-work-related explanatory variables to the analysis tripled the explained variance. CONCLUSIONS: The overall level of perceived stress can be statistically explained by a combination of work- and non-work-related stressors and perceived social support both at population level and in subgroups. The most important explanatory variables of overall perceived stress are disease, perceived social support and work situation. Results indicate that public health strategies aiming to reduce stress should take a comprehensive approach and address a variety of stressor domains rather than focus on a single domain. TRIAL REGISTRATION: The study was approved by the Danish Data Protection Agency (r. no. 2012-58-0006) and registered in the Central Denmark Region (r. no. 1-16-02-593-16).

RESUMEN

The global emergency caused by the novel coronavirus (COVID-19) pandemic has impacted access to goods and services such as health care and social supports, but the impact on infant feeding remains unclear. Thus, the objective of this study was to explore how caregivers of infants under 6 months of age perceived changes to infant feeding and other food and health-related matters during the COVID-19 State of Emergency in Nova Scotia, Canada. Four weeks after the State of Emergency began, between 17 April and 15 May 2020, caregivers completed this online survey, including the Perceived Stress Scale. Participants (n = 335) were 99% female and mostly White (87%). Over half (60%) were breastfeeding, and 71% had a household income over CAD$60,000. Most participants (77%) received governmental parental benefits before the emergency, and 59% experienced no COVID-19-related economic changes. Over three quarters of participants (77%) scored moderate levels of perceived stress. Common themes of concern included social isolation, COVID-19 infection (both caregiver and infant), and a lack of access to goods, namely, human milk substitutes ('infant formula'), and services, including health care, lactation support, and social supports. Most COVID-19-related information was sought from the internet and social media, so for broad reach, future evidence-based information should be shared via online platforms. Although participants were experiencing moderate self-perceived stress and shared numerous concerns, very few COVID-19-related changes to infant feeding were reported, and there were few differences by socio-economic status, likely due to a strong economic safety net in this Canadian setting.

RESUMEN

INTRODUCTION: This research was conducted to investigate the severity of tinnitus, its impact on subject's daily, personal and emotional life, which varies widely across the age groups. METHODOLOGY: Sample population of 60 unilateral tinnitus subjects with normal hearing between the age ranges of 15-55years were divided into four age groups. Tinnitus severity was measured using tinnitus severity index, impact of tinnitus on daily life was documented through tinnitus handicap inventory and the stress levels through perceived stress scale. RESULTS: A high frequency tinnitus was observed in age group of 56-65years, in contrast to noise like tinnitus in subjects aged 15-25years. The tinnitus was found to be most handicapping (38-56; moderate handicap) in Group 4(56-65years), the perceived stress levels were also falling in very high range (21 and over). Tinnitus severity index did not show any significant difference between the Group 1:15-25yrs, Group 2: 26-40yrs, Group 3:41-55yrs, and however group 4(56-65 yrs) did report with mild severity. The outcomes of present study demonstrated that elderly subjects certainly require modifications in the test protocols and referrals to address to their significant responses to tinnitus.
