Influence of stress factors and socio-demographic characteristics on the sleep quality of nursing students

The interaction between stress and sleep disorders among foreign medical students in Georgia

OBJECTIVES

This study aimed to: a. Investigate daytime sleepiness, stress, and pre-sleep arousal prevalence among foreign medical students in Georgia. b. Explore gender-based associations between sleep and stress parameters.

METHODS

Mental health was assessed in 207 foreign medical students in Georgia using the Epworth Sleepiness Scale (ESS), Pre-Sleep Arousal Scale (PSAS), and Student-Life Stress Inventory (SLSI).

RESULTS

Most participants reported elevated stress levels and excessive daytime sleepiness (EDS). EDS affected 25.1% of students, with slightly higher prevalence in males. PSAS was prevalent in 97.1% of students. Stress was widely reported, with 78% experiencing it, with a higher prevalence in females. Significant correlations were observed between sleepiness and arousal, including somatic (r = 0.41) and total scores (r = 0.28). Sleepiness was also linked to stressors like pressure, changes, self-imposed stress, and overall self-evaluation stress (r = 0.45). Strong correlations existed between ESS, Total PSAS, and overall self-evaluation SLSI scores for both genders. Gender differences were observed in the associations with Cohen's d within the small to moderate size. Men showed significant associations between ESS and stressors: conflict, pressure, chances, all stress reaction categories, and total SLSI scores (p < 0.001). In women, ESS correlated significantly only with overall self-evaluation (p < 0.001). Excessive daytime sleepiness, especially with somatic and total PSAS, predicted total SLSI scores for the entire sample and both genders, with stronger predictive values for total PSAS.

CONCLUSION

The study reveals a high prevalence of clinical sleepiness and its significant correlation with pre-sleep arousal and stress among foreign medical students, with females experiencing more difficulties than males.

The Effect of a Sleep Intervention on Sleep Quality in Nursing Students: Study Protocol for a Randomized Controlled Trial

We develop a protocol for assessing the impact of an intervention aimed at improving sleep quality among university nursing students. The study is designed as a pilot randomized controlled trial to be applied during the 2022-23 academic year and is registered at Clinical Trials Gov website (NCT05273086). A total of 60 nursing students will be recruited from a Spanish university. They will be divided into two groups: (30) intervention group and (30) control group. The intervention group will attend two cognitive-behavioural therapy sleep programme sessions focused on knowledge of anatomical structures involved in sleep, chronotype, synchronization, and good sleeping habits. Subjective and objective sleep quality will be assessed before and after the intervention for both groups. In addition to sleep quality, socio-demographic parameters, physical activity, lifestyle habits, and anthropometric measures will be considered prior to intervention. Finally, a satisfaction questionnaire will be applied for posterior analysis. This study is an innovative, relevant intervention that aims to improve sleep quality among university nursing students. Both the approach and the use of objective and subjective validated outcome measurements are key features of this study.

A cross-sectional study on sleep disturbances and associated factors among nurses

BACKGROUND

Many studies have measured sleep disturbances among nurses globally, but none have addressed this issue in Vietnam. Therefore, this study aimed to assess the prevalence of sleep disturbance and identify associated factors among staff nurses in Vietnam. To identify sleep disturbances and associated factors among staff nurses in Vietnam.

METHODS

A cross-sectional design was used in this study. Participant nurses (n = 420) completed a general information questionnaire, the Vietnamese version of the General Sleep Disturbance Scale (GSDS), the Perceived Stress Scale, and the Short Form 12. Data were collected between July and September 2019 from three public hospitals located in southwestern Vietnam. Data were analyzed using Chi-square, independent Student's t-test, and multivariate logistic regression analysis.

RESULTS

The average GSDS score was 41.10 (SD = 19.48), indicating sleep disturbances among 46.9% of nurses. Age, health condition, stress, and quality of life had an impact on sleep disturbance. Multivariate logistic regression analysis confirmed that nurses with high stress and poor physical health status were more likely to experience sleep disturbances.

CONCLUSION

Vietnamese nursing staff suffers from a high rate of sleep disturbances. Significant predictors included high stress and poor physical health status. Administrators of healthcare services should carefully consider how to conduct interventions to help the nurses handle their sleep disturbances such as stress management and physical health promotion.

Sleep quality and work among nursing vocational students

OBJECTIVES

to analyze quality of sleep among students of technical courses in nursing according to the exercise of work activity.

METHODS

a cross-sectional and analytical research, with 213 students from Paraná. Characterization data and the Pittsburg Sleep Quality Index were collected between March and June 2020 and analyzed descriptively and inferentially.

RESULTS

quality of poor sleep was 76.5% among those who work and 75.3% among those who do not work. Difficulty in reconciling personal and academic life (p=0.016;adjOR:3.450) and indicating anxiety due to school activities (p=0.017;adjOR:3.236) increased the chances of poor sleep quality among working students. Satisfaction with health reduced the chances of poor sleep quality, regardless of exercising work activity (p=0.002;adjOR:0.210) or not (p=0.008;adjOR:0.215).

CONCLUSIONS

students who performed work activities have worse sleep quality due to anxiety and the multiple activities to be reconciled with the study.

The relationship of sleep quality among internship nurses with clinical learning environment and mental stress: a cross-sectional survey

BACKGROUND

Previous evidence has supported an association between sleep quality and psychological stress. However, the association between internship nurses' sleep status and its relevant factors is poorly understood.

OBJECTIVE

The aim of this study was to investigate sleep quality and its related factors in clinical learning environment and mental stress.

METHODS

A cross-sectional survey was conducted by three instruments: Clinical Learning Environment, Supervision, and Nurse Teacher Evaluation Scale (CLES + T), Stress Rating Scale for practicing nurses (SRS) and Pittsburgh Sleep Quality Index (PSQI).

RESULTS

A total of 508 (91.86%) of 553 students experienced poor sleep quality. The structural equation model showed a correlation of the PSQI with the CLES + T (r = -0.21, p < 0.001), a correlation of the PSQI with the SRS (r = 0.32, p < 0.001), and a correlation of the SRS with the CLES + T (r = -0.22, p < 0.001). Linear regression analysis showed that education (B = -0.56, p < 0.001), willingness to engage in nursing after graduation (B = -0.75, p < 0.001), pedagogical atmosphere in the ward (B = -0.05, p < 0.001) measured by the CLES + T, workload (B = 0.11, p = 0.01), interpersonal relationships (B = -0.12, p = 0.03), and conflicts between study and work (B = 0.12, p < 0.001) on the SRS were significant factors influencing the PSQI.

CONCLUSIONS

Poor sleep quality is common among internship nurses and it's affected by clinical environment and mental stress. It's necessary to apply more tailored education programs to promote nursing development.

Effect of therapeutic touch on daytime sleepiness, stress and fatigue among students of nursing and midwifery: A randomized sham-controlled trial

OBJECTIVES

This study was conducted to assess the effect of therapeutic touch on stress, daytime sleepiness, sleep quality and fatigue among students of nursing and midwifery.

METHODS

96 students were randomized into three groups: the therapeutic touch (TT) group, the sham therapeutic touch (STT) group, and the control group. In this randomized sham-controlled study, the TT group was subjected to therapeutic touch twice a week for four weeks with each session lasting 20 min.

RESULTS

When the TT group was compared to the STT and control groups following the intervention, the decrease in the levels of stress (p < 0.001), fatigue (p < 0.001) and daytime sleepiness (p < 0.001), and the increase in the sleep quality (p < 0.001) were found to be significant.

CONCLUSION

It was found that TT, which is one form of complementary therapy, was relatively effective in decreasing the levels of stress, fatigue and daytime sleepiness, and in increasing the sleep quality of university students of nursing and midwifery.

Association between Sleep Quality and Duration and Periodontal Disease among University Students: A Cross-Sectional Study

The purpose of this cross-sectional study was to investigate the association between sleep quality and duration, and periodontal disease among a group of young Japanese university students. First-year students (n = 1934) at Okayama University who voluntarily underwent oral health examinations were included in the analysis. Sleep quality and duration were assessed by the Japanese version of the Pittsburgh Sleep Quality Index. Dentists examined Oral Hygiene Index-Simplified (OHI-S), probing pocket depth (PPD), and percentage of sites with bleeding on probing (BOP). Periodontal disease was defined as presence of PPD ≥ 4 mm and BOP ≥ 30%. Overall, 283 (14.6%) students had periodontal disease. Poor sleep quality was observed among 372 (19.2%) students. Mean (± standard deviation) sleep duration was 7.1 ± 1.1 (hours/night). In the logistic regression analysis, periodontal disease was significantly associated with OHI-S (odds ratio [OR]: 2.30, 95% confident interval [CI]: 1.83–2.90; p < 0.001), but not sleep quality (OR: 1.09, 95% CI: 0.79–1.53; p = 0.577) or sleep duration (OR: 0.98, CI: 0.87–1.10; p = 0.717). In conclusion, sleep quality and duration were not associated with periodontal disease among this group of young Japanese university students.

Stress level among undergraduate nursing students related to the training phase and sociodemographic factors

OBJECTIVE

identify the stress level among nursing undergraduates and the associated sociodemographic and academic factors; to compare stress level among college students according to the training phase in the course.

METHOD

cross-sectional study with 286 university students. The instrument of sociodemographic and academic characterization and the stress scale were applied. The overall stress level was assessed by standardized score. In the bivariate analysis, Pearson's chi-square or Fisher's exact test was used, and multiple logistic regression analysis was performed using the Poisson model. Statistical significance of 5% was adopted.

RESULTS

higher proportion of college students presented medium/high level of global stress. Students from 6th to 10th semesters presented higher levels of stress compared to those from 1st to 5th, in the Realization of practical activities, Professional Communication (p = 0.014), Environment (p = 0.053) and Vocational Training (p = 0.000) domains). In the multivariate analysis, they contributed to the highest level of stress the variables attending the 6th to 10th semesters, female gender, monthly income ≤ one minimum wage and income considered insufficient.

CONCLUSION

women in a more advanced stage of education and with low economic condition present a higher level of stress in their academic education.

Novice nurses' sleep disturbance trajectories within the first 2 years of work and actual turnover: A prospective longitudinal study

BACKGROUND

Novice nurses experience radical changes in their sleep-wake cycle and sleep difficulties after exposure to a rotating shift work schedule. The link between workplace hardship and employee turnover may be dependent on factors at the individual level, e.g., individual health. Nurses with sleep disturbance are more vulnerable to stressful stimuli and lack resilience at work compared with those without sleep disturbance.

OBJECTIVES

To classify novice nurses according to sleep disturbance trajectories during the first 2 years of work, to compare turnover rates according to trajectory classification, and to compare levels of sleep disturbance between stayers and leavers within each trajectory class.

DESIGN

Prospective longitudinal design.

SETTINGS

A tertiary hospital in Seoul, South Korea.

PARTICIPANTS

A total of 465 newly graduated nurses who started work between September 2014 and December 2015.

METHODS

Data were collected 6 times within the first 2 years of work (on the first day of orientation before ward placement, at 6 weeks after starting work, and at 6, 12, 18, and 24 months of work). Sleep disturbance was assessed using the General Sleep Disturbance Scale. Turnover information was retrieved from the hospital's administrative data system to determine whether anyone had left the hospital at each data collection point. Unconditional latent growth curve analysis was performed to identify latent classes of trajectories of sleep disturbance among novice nurses during the first 2 years of work.

RESULTS

The 2-year trajectories of sleep disturbance were classified into two distinct groups: the high symptomatic group (Class 1: 57.4%) and the low symptomatic group (Class 2: 42.6%). In comparison with Class 2, Class 1 consistently showed a higher turnover in each period. In Class 1, leavers who left the hospital at the next measurement point tended to report more severe sleep disturbance at prior measurements. This pattern was also observed for the overall sample. However, in Class 2, an inconsistent pattern between stayers and leavers was observed.

CONCLUSIONS

This study identified two distinct classes of sleep disturbance among novice nurses during the first 2 years of work. Given that many nurses experience sleep problems at pre-employment and during the early career period, a comprehensive approach to address this issue should be implemented in nursing schools and hospitals. The basic nursing curriculum should include self-care management strategies for sleep difficulties to ensure retention at work. At-risk nurses should receive organizational support and early monitoring to prevent the adverse effects of poor sleep.

IMPACT OF SELF-ESTEEM AND OF THE SOCIODEMOGRAPHIC FACTORS ON THE SELF-EFFICACY OF UDERGRADUATE NURSING STUDENTS

ABSTRACT Objectives: to identify self-efficacy and self-esteem levels in undergraduate nursing students and to verify the mutual relationship between these constructs and with sociodemographic variables. Method: a cross-sectional study, with a sample of 264 students from two universities. Self-esteem and self-efficacy were measured by the Brazilian versions of the Rosenberg's Self-Esteem and of the General and Perceived Self-Efficacy scales, respectively. Results: a predominance of moderate to high self-efficacy was identified, with a mean score of 35.29 and moderate self-esteem, with a mean of 23.48. Self-efficacy was associated with the male gender, priority option in the college entrance examination by nursing, satisfaction with the course and absence of overload, besides correlating positively with age and self-esteem. Conclusion: self-efficacy and self-esteem levels were moderate/high and moderate, respectively. These constructs have shown a mutual relationship and assume an indispensable role both in the individual's personal life and in the professionalization process. These findings point to the need to strengthen mental health in this population, especially in vulnerable students (female, activity overload, dissatisfaction with the course and low self-esteem and self-efficacy), in order to foster their sense of value and the belief in their abilities.

Reliability and Repeatability of the Instrument for the Assessment of Stress in Nursing Students (ASNS)

Background and objectives: Stress in nursing students is a very common experience, especially when they face clinical practice. The aims of this study were to perform a transcultural adaptation and to examine the reliability and repeatability of the Instrument for the Assessment of Stress in Nursing Students for a Spanish population. Methods: A test–retest analysis was carried out in two face-to-face sessions with the students with a lapse of 10 days between the two sessions. A cross-sectional descriptive study was carried out between the months of May and June 2018. Sixty-four nursing students were recruited with a consecutive sampling method that targeted individuals in the freshman class. Results: A good internal consistency was shown for the total score (α = 0.8861) and for each of the six domains. The test–retest reliability, using the Wilcoxon paired test, was not significant, indicating no differences between the total scores or the domain scores (p ≥ 0.05). Finally, Bland and Altman plots of visual distributions did not show differences between the total scores and the domain scores. Conclusion: The Instrument for the Assessment of Stress in Nursing Students was shown to be a reliable tool for measuring stress factors among Spanish nursing students.

Health alterations in nursing students after a year from admission to the undergraduate course

OBJECTIVE

To identify health alterations in nursing students after a year from admission to a nursing undergraduate course.

METHOD

A longitudinal prospective study with a quantitative approach was carried out in 2016 with first-year nursing students from two universities in the state of São Paulo. The following instruments were applied at the beginning and the end of the first school year: an instrument for Assessment of Stress in Nursing Students, the Center for Epidemiologic Studies Depression Scale, and the Pittsburgh Sleep Quality Index. The ANOVA test for mixed models was used for analysis.

RESULTS

The sample was made up of 117 students in March and 100 students in December. A significant increase in stress in all dimensions of the instrument, a reduction in the duration and subjective quality of sleep, and an increase in general stress and depressive symptoms were observed.

CONCLUSION

The nursing academic environment presents the potential for students to become ill. Institutions should rethink their curricular elements, promote resilience, and create spaces to promote students' health.

Comparison of stress in freshman and senior nursing students

OBJECTIVE

To compare stress levels in freshman and senior nursing students.

METHOD

A cross-sectional study was carried out in a public federal university of the state of Bahia, with students who answered questionnaires about sociodemographic variables, academic life, and a scale for assessing stress in nursing students. Chi-square and Fisher's exact tests were applied to analyze the relationship between variables. To assess proportional trends between ordinal variables and groups, a chi-square test for linear trend was applied. The significance level was 5%.

RESULTS

One hundred and fifty-four students participated in the study. There was a tendency to higher stress levels among students in the last year compared to those in the first year, in four out of six domains: Performance of Practical Activities (p=0.00), Professional Communication (p=0.00), Environment (p=0.00) and Professional Education (p=0.00).

CONCLUSION

High levels of stress were observed in students taking the last year. There is a need for broader research that includes other years of the course, an institutional reflection on stress factors and the adoption of an institutional policy that favors a better confrontation of stress factors.

A study of comparing two cognitive-behavioral workshop for college students: Sleep, wakefulness program and perseverance program

Introduction and Aim:

Researchers and specialists believe that health maintenance and improvement through university students, as a part of society, play a crucial role in community configuration which should not be ignored. Since there was a few studies in these fields, researchers have sought to explore how mentioned workshops is related to cognitive emotion regulation, anxiety, depression, and sleep quality for the student volunteers of Shiraz University of Medical Sciences.

Materials and Methods:

In a randomized controlled trial, 152 students were allocated into the 3 equal groups (study1: “perseverance workshop” study2:”sleep and wakefulness workshop” and control group). Data collection instruments were the Granovsky cognitive emotion regulation scale, the Beck depression and anxiety inventories and Pittsburgh sleep Quality Index (PSQI-P) Questionnaire.

Results:

The results of comparing the anxiety and depression between groups showed that there was a decreasing and significant trend in the two intervention groups, before and after the two workshops (P < 0.001). For PSQ analysis, within-group comparisons in those who have participated sleep and wakefulness workshop showed that the change trend was significant and in linear form. In addition, to compare those who have participated in perseverance workshop with the control group, there was a significant difference between the pretest and posttest results in the Cognitive Emotion Regulation subgroups.

Conclusion:

It can be said that the implementation of the workshops could improve the emotional state of the participants in comparison to the control group.

Comparison of the Status of Sleep Quality in Basic and Clinical Medical Students

Introduction

Academic pressure and its associated stress are responsible for disturbances in the circadian cycle of the students. Adequate sleep has crucial role in enhancing cognitive skills especially memory retention. Poor night time sleep quality and consequent daytime sleepiness affects physical and cognitive health of the students. In this study, sleep quality among medical students is evaluated.

Methods

It was an observational, cross-sectional study conducted with undergraduate medical students. Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality. The data was analyzed using Statistical Package for the Social Sciences (SPSS) 22.0 (IBM Corp., Armonk, NY, USA).

Results

Of 281 students, 155 (55.16%) were pre-clinical students and 126 (44.83%) were clinical students; 207 (73.66%) were female students and 74 (26.33%) were male. The overall frequency of poor sleepers was 172 (61.2%); 95 (55.2%) of these were clinical sciences and 77 (44.8%) were basic sciences students. Sleep latency, duration, and efficiency were more impaired in clinical students (p-value ≤ 0.05). Use of sleep medications and daytime dysfunction was more common in clinical students (p-value ≤ 0.05).

Conclusion

Medical students are continuously under high academic stress and pressure. Adequate sleep is essential for them to refresh them every day and help in learning and memory processing. Medical students in advance years of education have worse sleep quality than those in early years. Efforts should be taken to improve their sleep quality in order to protect the psychological and emotional health of future doctors.

Stress of nursing students in clinical simulation: a randomized clinical trial

OBJECTIVE

To evaluate and compare the perception of stressors by nursing students before and after a high-fidelity clinical simulation or conventional laboratory practice class.

METHOD

This is a randomized clinical trial conducted with 52 nursing students. Both groups had theoretical classes about cardiothoracic physical examination, followed by practice class in skill laboratory. In addition, the experimental group took part in a high-fidelity simulation scenario. Stressors were evaluated before and after class, with the application of KEZKAK questionnaire.

RESULTS

The experimental group was significantly more worried about six factors related to lack of competence and to interpersonal relationships (p < 0.05), while the control group was significantly more worried about being in contact with suffering (p = 0.0315).

CONCLUSION

The simulation affects students' perception of stressors and promotes their self-evaluation and critical thinking regarding the responsibility that comes with their learning.

Sleep quality in medical students: a comparison across the various phases of the medical course

OBJECTIVE

To evaluate and compare subjective sleep quality in medical students across the various phases of the medical course.

METHODS

This was a cross-sectional study involving medical undergraduates at one medical school in the city of Botucatu, Brazil. All first- to sixth-year students were invited to complete the Pittsburgh Sleep Quality Index, which has been validated for use in Brazil. Participants were divided into three groups according to the phase of the medical course: group A (first- and second-years); group B (third- and fourth-years); and group C (fifth- and sixth-years). The results obtained for the instrument components were analyzed for the total sample and for the groups.

RESULTS

Of the 540 students invited to participate, 372 completed the instrument fully. Of those, 147 (39.5%) reported their sleep quality to be either very or fairly bad; 110 (29.5%) reported taking more than 30 min to fall asleep; 253 (68.0%) reported sleeping 6-7 h per night; 327 (87.9%) reported adequate sleep efficiency; 315 (84.6%) reported no sleep disturbances; 32 (8.6%) reported using sleeping medication; and 137 (36.9%) reported difficulty staying awake during the day at least once a week. Group comparison revealed that students in group A had worse subjective sleep quality and greater daytime dysfunction than did those in groups B and C.

CONCLUSIONS

Medical students seem to be more exposed to sleep disturbance than other university students, and first- and second-years are more affected than those in other class years because they have worse subjective sleep quality. Active interventions should be implemented to improve sleep hygiene in medical students.

Evaluation of social support and stress in nursing students

OBJECTIVE

To analyze the perception of stress and social support of nursing students considering the number of supporters and the satisfaction with them.

METHOD

Quantitative, cross-sectional study performed with nursing students from a public university in the state of São Paulo, Brazil. We used the Stress Evaluation in Nursing Students scale and the Social Support Questionnaire. We performed the chi-squared test and analyzed the structure of the support network using software Gephi version 0.9.1.

RESULTS

192 students participated. Family and friends were the most mentioned supporters. Despite counting on a low number of supporters, most participants were satisfied with the perceived support. The students presented high intensity of stress in the "professional training" domain. Furthermore, the students who were pleased with the perceived social support presented low intensity of stress in accomplishing the theoretical activities of the undergraduate course.

CONCLUSION

The creation of more welcoming spaces in the academic environment, the qualification of the social support, and the employment of strategies to improve the transition from the student stage to the professional stage are important recommendations that will contribute for positive outcomes regarding the coping with student stress.

Short version of the "instrument for assessment of stress in nursing students" in the Brazilian reality

Goal:

validate a short version of the Instrument for assessment of stress in nursing students in the Brazilian reality.

Method:

Methodological study conducted with 1047 nursing students from five Brazilian institutions, who answered the 30 items initially distributed in eight domains. Data were analyzed in the R Statistical Package and in the latent variable analysis, using exploratory and confirmatory factor analyses, Cronbach’s alpha and item-total correlation.

Results:

The short version of the instrument had 19 items distributed into four domains: Environment, Professional Training, Theoretical Activities and Performance of Practical Activities. The confirmatory analysis showed absolute and parsimony fit to the proposed model with satisfactory residual levels. Alpha values ​​per factor ranged from 0.736 (Environment) to 0.842 (Performance of Practical Activities).

Conclusion:

The short version of the instrument has construct validity and reliability for application to Brazilian nursing undergraduates at any stage of the course.

Stress among nursing undergraduate students of a Brazilian public university

OBJECTIVES

To determine the level of stress among students of an undergraduate course in nursing of a Brazilian public university.

METHODS

Cross-sectional study involving 111 students who responded to the 30 item questionnaire of Costa and Polak for the Assessment of Stress among Nursing Students, with Likert type response options of 0-3 (0 = I have not experienced the situation; 1 = I do not feel stressed with the situation; 2 = I feel a little stressed with the situation, and 3 = I feel very stressed with the situation).

RESULTS

Participants were predominantly single (82.9%), female (83.8%), young adults (mean 23.3 years) and performing some kind of paid work (76.6%). The main stressors were related to the lack of time for: leisure activities (2.6); spending time with family members (2.5) and; completion of extracurricular activities (2.3). The highest levels of stress among students were found in the domains of professional training (52.2%), professional communication (33.3%) and time management (32.4%).

CONCLUSIONS

The majority of the students presented low levels of stress in the general activities of the course, however, the activities related to time management, especially time for academic activities and social and family life, were identified as permanent stress factors during the graduation course.

Reliability and Validity of the 4-Item Version of the Korean Perceived Stress Scale

This study was designed to evaluate the reliability (internal consistency, reproducibility over time, and measurement precision) and validity (factorial, convergent, and concurrent validity) of the 4-item Korean Perceived Stress Scale in comparison to the 10-item Korean Perceived Stress Scale. Participants were 650 students from seven schools of nursing in South Korea. Measures included Korean versions of the Perceived Stress Scale, the Pittsburgh Sleep Quality Index, and a single-item quality-of-life measure. The 4-item Perceived Stress Scale had lower Cronbach alpha than the 10-item Perceived Stress Scale (.65 vs. .80), but its item-total correlations (.35-.47) and split-half coefficient (.81) were comparable to the 10-item Perceived Stress Scale (item-total correlations = .20-.56; split-half coefficient = .82). Reproducibility of the 4-item scale after a 1-week interval (r = .67, ICC absolute agreement = .64) was similar to the 10-item scale (r = .70, ICC absolute agreement = .65). The standard error of measurement was slightly higher in the 4-item scale. Scale constructs of the two were identical in exploratory factor analysis. The two scales were highly correlated (r = .93) and showed similar levels of concurrent validity with sleep quality and quality of life. In conclusion, the 4- and 10-item Korean Perceived Stress Scale are similar in psychometric qualities. © 2016 Wiley Periodicals, Inc.
