The Satisfaction with Life Scale in breast cancer patients: Psychometric properties

Promoting Mental Health in Adolescents Through Physical Education: Measuring Life Satisfaction for Comprehensive Development

Background: Life satisfaction serves as a preventive agent against various emotional, cognitive, and behavioral challenges, making it a crucial cognitive indicator of subjective well-being, particularly during adolescence. Accurately assessing life satisfaction is essential for understanding and promoting adolescent mental health, especially in applied settings such as physical education, which plays a key role in fostering psychological well-being and positive youth development. However, additional investigation is needed to confirm the tools used for this purpose. This study aimed to analyze the psychometric properties, metric invariance, and temporal stability of the Satisfaction with Life Scale (SWLS) in adolescents from a region in southeastern Spain. Thus, the present study sought to answer the following research questions: (1) Does the SWLS demonstrate adequate psychometric properties in an adolescent population? (2) Is the SWLS invariant across gender and residential environments? (3) Does the SWLS show adequate stability over time? Methods: A sample of 400 students was assessed using exploratory and confirmatory factor analyses, multigroup comparisons, and test-retest techniques. Results: The results showed significant differences in scale scores in the sex and demographic location variables. Also, a robust unifactorial model with five items demonstrated good performance in terms of goodness of fit and internal consistency. Furthermore, full metric invariance was observed across genders, while configural invariance was supported for residential environment. Concurrent validity analyses revealed significant associations with another unidimensional well-being measure, and temporal stability was confirmed through the intraclass correlation coefficient. Conclusions: The findings support the SWLS as a potentially valid, reliable, and time-effective tool for assessing adolescent life satisfaction. Its strong psychometric properties make it highly suitable for use in mental health research, longitudinal monitoring, and large-scale studies. Moreover, its ease of administration allows its integration into educational, clinical, community-based, and physical education contexts, offering insightful information for the creation of long-lasting mental health regulations and preventive measures meant to improve the well-being of adolescents. Notwithstanding these encouraging results, some restrictions must be noted. The sample was restricted to a single geographic area, and contextual or cultural factors may have an impact on how satisfied people are with their lives. Furthermore, response biases could have been introduced by using self-report measures.

Factorial Invariance of the Satisfaction with Life Scale (SWLS) in Mexican and Colombian University Students

This study aimed to evaluate the psychometric equivalence of the Satisfaction with Life Scale (SWLS) in university students from Mexico and Colombia. A non-probabilistic convenience sampling was used in five public and private universities in both countries, with a sample of 861 university students (40% men and 60% women), whose average age was 20.55 years (SD = 2.72). A six-point version of the SWLS was employed. Through confirmatory factor analysis, a unidimensional structure of the SWLS was identified in both samples, with adequate fit indices in both countries. Additionally, the factorial invariance analysis confirmed the metric and configural equivalence of the model, indicating that the factorial structure and factor loadings are comparable between both populations. The results support the use of the SWLS to assess life satisfaction in the context of university education in Mexico and Colombia.

Ability emotional intelligence profiles and real-life outcomes: a latent profile analysis of a large adult sample

Few studies have examined emotional intelligence (EI) following a person-centered approach to identify different types of EI profiles and their relationship to everyday life outcomes. Even rarer are those using an "ability" approach of EI (AEI) and related "performance-based" tests, which are considered promising. This study fills this gap by identifying AEI profiles and linking them to everyday outcomes such as health, wellbeing, and decision-making. The QEg ("QE" for Emotional Quotient - Quotient Emotional in French - and "g" for the general population), an ability-based measure of EI, along with other measures, was administered to 2,877 French adults. We then ran latent profile analysis (LPA) and identified three latent profiles within a heterogeneous population. The full emotion processing (FEP) profile outperforms the two others on key domains of life such as stress perception, home-work interaction, gratitude and satisfaction with life, emotional burnout prevention, and decision-making. Our research reveals the need for individualized AEI training programs tailored to three distinct profiles, addressing foundational skills for those with minimal or partial emotional processing while refining existing strengths for those with full emotional processing. Targeting interventions to specific profile characteristics could enhance the effectiveness of AEI training and promote improved wellbeing and life outcomes.

Investigation on the Changes of Perioperative Psychological State of Young Patients With Early Breast Cancer

OBJECTIVE

This study aims to explore the variations and dynamics in the mental states of young patients with early breast cancer across different perioperative periods and to analyse how different surgical methods impact these patients' psychological well-being.

METHODS

A prospective observational study was conducted on young patients with early breast cancer who underwent surgery from March 2021 to March 2022. Mental status questionnaires were administered at four key time points: preoperatively, 1 month, 6 months and 1 year postoperatively. The collected data were statistically analysed to discern the psychological shifts in these patients throughout the perioperative timeline. The patients were categorized into either the breast-conserving or mastectomy group based on their surgical procedure, and their mental state scores during each phase were analysed to investigate the effects of different surgical methods on their psychological health.

RESULTS

During the study period, 149 young patients with early breast cancer completed the four-phase questionnaire. Statistically significant differences were observed in self-evaluation, self-esteem, physiological state, fear of death, economic stress, negative emotion, and anxiety and depression among these patients across different periods. The baseline data revealed differences in marital status, place of residence and prior tumour history between the two surgical groups. Significant differences in self-evaluation, depression, self-esteem and positive emotions were found between the breast-conserving group and mastectomy groups.

CONCLUSION

Breast cancer presents significant physical and psychological challenges from diagnosis through treatment. Our findings indicate that young patients with early breast cancer experience varying degrees of psychological distress during the entire perioperative period, influencing their surgical choices and postoperative recovery. This study found that the psychological state of patients undergoing breast-conserving surgery is more favourable compared with that of patients who received mastectomies, particularly in terms of self-assessment, self-esteem, positive affect and depression levels.

Psychological well-being and emotional intelligence in undergraduate nursing students as predictors of academic success

BACKGROUND

Academic performance is influenced by a complex interplay of multiple factors whose relationships often do not follow straightforward patterns. Despite extensive research, understanding of these dynamics remains inconclusive. In particular, several studies highlight that higher emotional intelligence is associated with better academic outcomes and that people with elevated levels of psychological well-being also tend to achieve higher grades.

OBJECTIVE

This study examines the associations between emotional intelligence, psychological well-being and academic performance among undergraduate nursing students. Specifically, it seeks to deepen our understanding of how emotional intelligence affects academic achievement, with psychological well-being potentially serving as a mediator.

DESIGN

A cross-sectional correlational design was employed.

SETTINGS

The study involved a convenience sample of undergraduate nursing students from various degree programmes affiliated with the primary author.

PARTICIPANTS

394 undergraduate nursing students participated in the study, 249 identified as female and 145 as male.

METHODS

Participants completed a quantitative survey during class hours, providing data on demographics, academic average scores and self-report measures of perceived emotional intelligence and psychological well-being. Data were evaluated using Pearson's correlations and serial multiple mediation analyses.

RESULTS

The findings revealed significant positive relationships between emotional intelligence, psychological well-being and academic performance. Serial mediation assessments indicated that dimensions of emotional intelligence influence academic performance both directly and indirectly through psychological well-being. Specifically, flourishing partially mediated the relationship between emotional intelligence and academic performance, directly influencing academic outcomes.

CONCLUSIONS

This study underscores the critical role of emotional management skills in academic performance, with psychological well-being acting as a partial mediator in this relationship. Consequently, undergraduate nursing students with enhanced emotional management abilities and higher levels of psychological well-being are likely to achieve better academic outcomes.

Psychometric properties of the Depression Anxiety Stress Scales (DASS-21) in women with breast cancer

Breast cancer impacts the psychological well-being of women, leaving them at risk of developing depression, anxiety, and other stress-related disorders. The Depression Anxiety Stress Scales (DASS-21) is a widely used measure, although empirical evidence regarding its psychometric properties in the breast cancer population is limited. The purpose of this study was to conduct an exhaustive analysis of the psychometric properties of the DASS-21 in a sample of Spanish women diagnosed with breast cancer. Participants were 289 breast cancer patients who completed the DASS-21 and other questionnaires measuring life satisfaction, positive and negative affect, flourishing, perceived stress, and breast cancer-specific stressors. In terms of validity evidence based on the internal structure of the DASS-21, adequate fit indices were obtained for the model based on three first-order factors (depression, anxiety, stress) and one second-order factor (general psychological distress). Reliability coefficients (McDonald's omega) ranged from .84 to .95. Validity evidence based on relationships with other variables was also provided by moderate and strong correlations with well-being indicators and stress measures. The results support the use of the DASS-21 for measuring general psychological distress in the breast cancer context, where it may provide useful information for the design of psychological interventions with patients.

New Psychometric Evidence of the Life Satisfaction Scale in Older Adults: An Exploratory Graph Analysis Approach

The objective of the present study was to analyze the psychometric properties of a life satisfaction scale in older Peruvian adults using an exploratory graph analysis (EGA) approach. A total of 407 older adults aged between 60 and 95 years (M = 69.5; SD = 6.7) from three comprehensive elderly care centers (CIAMs) in Lima, Peru, were recruited. A non-probabilistic convenience sampling was used. The Satisfaction with Life Scale (SWLS) was analyzed using EGA with the Gaussian GLASSO model to assess its dimensionality and structural consistency. The relationship with other variables was analyzed using scales such as the GAD-7 and PHQ-9. The network structure of the SWLS indicates a single dimension. Additionally, network loadings (nodes) were examined, showing high values (>0.35) for most items except item 1, which had a moderate loading (>0.25). Structural reliability showed that a single dimension was identified 100% of the time. The post hoc CFA considering the unidimensional network structure obtained through EGA showed satisfactory fit (χ2/df = 3.48, CFI = 0.96, TLI = 0.92, SRMR = 0.02, RMSEA = 0.07 [90% CI 0.05, 0.08]). Finally, internal consistency reliability was acceptable (ω = 0.92). The SWLS measure is robust and consistent. These findings are a valuable reference for advancing research on aging in Peru, as they provide a practical, valid, and reliable measure.

A study of the relationship and mediating effects of perceived stress and post-traumatic growth in patients undergoing postoperative chemotherapy for breast cancer

OBJECTIVE

The traumatic experience of cancer, in addition to its negative impact on breast cancer patients, can also bring about positive change, i.e., post-traumatic growth (PTG). PTG can help boost patients' confidence in their fight against the disease and improve their adherence to treatment, thereby facilitating their recovery. The study aimed to investigate the effect of perceived stress on the PTG of patients undergoing postoperative chemotherapy for breast cancer and to examine the roles of rumination and self-efficacy between two.

METHODS

The data was collected using a cross-sectional design. From December 2021 to October 2022, a total of 306 breast cancer patients who had undergone chemotherapy following surgery and met the inclusion and exclusion criteria were selected from three tertiary-level A hospitals in Henan Province, China. We conducted descriptive analysis, Pearson correlation analysis, and a regression analysis using PROCESS Macro Model 80 to explore the relationships among perceived stress, rumination, self-efficacy, and PTG.

RESULTS

Perceived stress of patients undergoing postoperative chemotherapy for breast cancer had a negative predictive effect on PTG (r = -0.340, P < 0.01); Rumination and self-efficacy played a partial mediating effect between perceived stress and PTG, accounting for 45.25% of the total effect.

CONCLUSIONS

Clinical nursing staff could promote PTG by strengthening psychological assessment and timely psychological intervention for patients with high perceived stress levels, encourage patients to adopt a positive way of thinking about illness and improve their self-efficacy level, so as to improve their PTG level.

Temporal stability of optimism and pessimism (LOT-R) over 6 years in the general population

Objective

The aims of this study were to examine changes in habitual optimism over a six-year period and to analyze the relationship between changes in optimism and changes in other quality of life-related variables.

Method

A randomly selected community sample of the German adult general population (N = 4,965) was surveyed twice, with a time interval of 6.04 years.

Results

During the course of the 6 years, the mean score of the LOT-R total scale improved (effect size d = 0.11). The temporal stability in terms of the test-retest correlation was r = 0.61 for the total sample. There were only marginal gender differences in this temporal stability, however, the stability in the oldest age group ≥70 years (r = 0.50) was lower than the stability of the other age groups. The cross-sectional correlations showed clear relationships between optimism on the one hand and quality of life, life satisfaction, social support, and low levels of anxiety and physical complaints on the other. The corresponding longitudinal correlations between changes in optimism and changes in the other variables were less pronounced, but in the same direction.

Conclusion

The study confirmed the applicability of the LOT-R in longitudinal studies. In samples with participants of 70 years and above, the limited stability in the optimism assessments needs to be considered in clinical practice and epidemiologic research.

Emotional Intelligence and Breast Cancer: A Systematic Review

Emotional Intelligence (EI), defined as the ability to perceive, identify, understand, and regulate emotional states is related to health outcomes. In this line, some studies examined this personal resource in the cancer area and, specifically, in breast cancer. Also, the different models and measures have led to a categorisation considering the various construct-method pairings of EI. Despite the increased number of studies about EI in the breast cancer context, there are no systematic reviews that summarise the results obtained in the different investigations. Objectives: Hence, the present review aims: to identify and describe the measures that have been used for assessing EI within this field, and to summarise the main results regarding EI in terms of its predictors and outcomes, considering the instruments used to assess it. Methods: The PRISMA guidelines were followed. Database search was conducted in WOS, Scopus, Pubmed, and PSYCArticles. Results: A total of 156 articles were found and 21 met the eligibility criteria. On one hand, one of the most used instruments was the TMMS-24 framed within the self-report ability EI, followed by those framed within the self-report mixed EI. None of the studies measured EI by the performance-based ability EI perspective. On the other hand, EI was related to other variables such as psychological well-being, quality of life, resilience, workability, anxiety, and depression. The majority of the studies were cross-sectional, and some of them included an intervention. Conclusions: This review provides a comprehensive overview of the existing studies concerning EI in the context of breast cancer, highlighting some of its characteristics regarding design, participants, used measures, and related variables. Also, the obtained results can improve the clinical practice and the understanding of the EI as an influencing factor in the health and quality of life of breast cancer populations.

A Network Analysis Study on the Structure and Gender Invariance of the Satisfaction with Life Scale among Spanish University Students

INTRODUCTION

The psychometric properties of the Satisfaction With Life Scale (SWLS) have been evaluated across numerous languages and population groups, primarily from a factor analysis perspective. In some studies, inconsistencies in structural invariance have been identified.

OBJECTIVE

This study aims to analyze the properties and gender invariance of the SWLS from a network analysis perspective.

METHOD

A total of 857 Spanish university students were obtained through a stratified random cluster sampling method in a cross-sectional survey design study. Descriptive analysis of the items, partial-correlation network, Bayesian network model estimation, and invariance analysis by gender were conducted.

RESULTS

The instrument did not exhibit any floor or ceiling effects. Each item can be considered univariately normally distributed, and all items clustered in a single and stable community. The partial-correlation network model and centrality measures were stable in the full sample and invariant across genders. Item 3 emerged as the most central node in the network with the highest predictability. The Bayesian network indicated that items 2 and 4 initiate the process, while item 5 acts as the sink, and items 1 and 3 act as mediators.

CONCLUSIONS

The SWLS can be used as a unidimensional measure, and the total score and relationships among items are stable and reliable. Any potential differences among genders cannot be associated with the functioning of the instrument. The predictability of every item was high, and the Bayesian network clearly identified different roles among the items.

The Flourishing Scale: Psychometric Properties in Breast Cancer Patients

BACKGROUND/OBJECTIVE

Promoting well-being is a key goal of cancer care, and it needs to be assessed using appropriate instruments. Flourishing is considered part of psychological well-being and it is commonly assessed with the Flourishing Scale (FS). To our knowledge, no studies have analyzed the psychometric properties of the FS in breast cancer patients. Our aim here was to provide validity evidence for use of the FS in this context.

METHOD

Participants were 217 Spanish women with breast cancer who completed the FS and other scales assessing positive psychology constructs (life satisfaction, positive affect, resilience, self-esteem, optimism) and indicators of psychological maladjustment (negative affect, depression, anxiety, and stress). The internal structure of the FS was analyzed using confirmatory factor analysis (CFA). We calculated the average variance extracted (AVE) to evaluate convergent validity, and both McDonald's omega and Cronbach's alpha coefficients to estimate reliability. Item analysis was performed by computing corrected item-total correlations. Validity evidence based on relationships with other variables was obtained through Pearson correlation analysis, controlling for age and cancer stage.

RESULTS

The CFA supported a single-factor structure, with adequate goodness-of-fit indices (CFI = 0.997, NNFI = 0.996, RMSEA = 0.069, and SRMR = 0.047) and standardized factor loadings ranging from 0.70 to 0.87. The value of the AVE was 0.63, and the reliability coefficient obtained with both procedures was 0.91. Corrected item-total correlations ranged from .62 to .78. Correlation analysis showed direct and strong associations between the FS score and scores on positive psychology constructs (range from 0.43 to 0.74), the strongest correlations being with positive affect and life satisfaction. The FS score was inversely correlated with scores on depression, anxiety, stress, negative affect, and pessimism (range from -0.14 to -0.52), the strongest association being with stress.

DISCUSSION

The FS is a useful tool for exploring well-being in the breast cancer context, providing useful information for psychological assessment.

Development and psychometric properties of the Stressors in Breast Cancer Scale

Background

A diagnosis of breast cancer generates psychological stress, due not only to treatment and its side effects but also to the impact on different areas of the patient’s daily life. Although there are instruments for measuring psychological stress in the cancer context, there is currently no tool for assessing stressors specific to breast cancer.

Aims

The aim of this study was to develop the Stressors in Breast Cancer Scale (SBCS).

Method

A panel of experts evaluated the clarity and relevance of scale items, providing validity evidence based on test content. Psychometric properties of the scale were then analyzed.

Results

Validity evidence based on the internal structure of the SBCS was obtained through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), following a cross-validation strategy. The CFA supported a second-order factor model with five dimensions: physical appearance and sex strains, health and daily difficulties, interpersonal relationship strains, healthcare strains, and worries and concerns about the future. This structure was invariant across two groups distinguished by time from cancer diagnosis (less than 3 and 3 years or more from diagnosis). Reliability, based on McDonald’s omega and Cronbach’s alpha coefficients, ranged from 0.83 to 0.89 for factor scores, and reached 0.95 for total scores. Validity evidence was also provided by correlations with depression, anxiety, perceived stress, and perceived health and quality of life.

Discussion

The results support the use of the SBCS for measuring stress as a stimulus in the breast cancer context. Implications for clinical practice and research are discussed.

High-intensity exercise prescription guided by heart rate variability in breast cancer patients: a study protocol for a randomized controlled trial

BACKGROUND

Breast cancer is a chronic disease with a large growth in its treatments, prognosis, improvements, side effects and rehabilitation therapies research. These advances have also highlighted the need to use physical exercise as a countermeasure to reduce the cardiotoxicity of pharmacological treatments, increase patients' strength and quality of life and improve body composition, physical condition and mental health. However, new investigations show the need for a closed exercise individualisation to produce higher physiological, physical and psychological benefits in remote exercise programs. To this end, the present study will use, in a novel way in this population, heart rate variability (HRV) as a measure for prescribing high-intensity training. Thus, the primary objective of this randomised clinical trial is to analyse the effects of a high-intensity exercise program daily guided by HRV, a preplanned moderate to high-intensity exercise intervention and a usual care group, in breast cancer patients after chemotherapy and radiotherapy treatments.

METHODS

For this purpose, a 16-week intervention will be carried out with 90 breast cancer patients distributed in 3 groups (a control group, a moderate to high-intensity preplanned exercise group and a high-intensity exercise group guided by HRV). Both physical exercise interventions will be developed remotely and supervised including strength and cardiovascular exercises. Physiological variables, such as cardiotoxicity, biomarkers, lipid profile, glucose, heart rate and blood pressure; physical measures like cardiorespiratory capacity, strength, flexibility, agility, balance and body composition; and psychosocial variables, as health-related quality of life, fatigue, functionality, self-esteem, movement fear, physical exercise level, anxiety and depression will be measure before, after the intervention and 3 and 6 months follow up.

DISCUSSION

Personalized high-intensity exercise could be a promising exercise intervention in contrast to moderate-intensity or usual care in breast cancer patients to reach higher clinical, physical and mental effects. In addition, the novelty of controlling HRV measures daily may reflect exercise effects and patients' adaptation in the preplanned exercise group and a new opportunity to adjust intensity. Moreover, findings may support the effectiveness and security of physical exercise remotely supervised, although with high-intensity exercise, to reach cardiotoxicity improvements and increase physical and psychosocial variables after breast cancer treatments.

The role of resilience in the relationship between role stress and psychological well-being during the COVID-19 pandemic: a cross-sectional study

BACKGROUND

Stress resistance resources, such as social support and resilience, have been found to be important in promoting psychological well-being during the COVID-19 pandemic. However, most prior research studies have conceptualized stress resistance resource variables as having a mediating or moderating role. Cooper (2018) proposed a model of the relationship between stress and health which posits that coping resources are always present and not only invoked in the face of adversity. Thus, we hypothesize that coping resources are causally antecedent to stressors and influence well-being indirectly via the stressor. We focused specifically on school teachers due to them being at the frontlines of service provision during the pandemic. Teaching was already identified as a highly stressful profession prior to COVID-19 and disease containment measures placed additional strain on teachers who had to adapt to emergency remote teaching.

AIM

The current study tests this hypothesis by examining the indirect effects of resilience on indices of psychological health via role stress.

METHODS

Participants (N = 355) were teachers who completed the Connor-Davidson Resilience Scale-10, the Role Stress Scale, the Satisfaction with Life Scale, the State-Trait Anxiety Inventory-Trait Scale, and the Center for Epidemiological Studies Depression Scale. An electronic version of the questionnaires was distributed to teachers via Facebook and to officials from the Department of Education, who assisted with distribution of the electronic link to the survey. Participants were mostly women (76.6%) and mean number of years in the teaching profession was 15.7.

RESULTS

Structural equation modelling results demonstrated significant direct effects of resilience on life satisfaction, anxiety, and depression, which indicates that resilience is beneficial for psychological health even in the absence of stress. Resilience also had a significant indirect effect on indices of psychological well-being via role ambiguity but not role conflict.

CONCLUSION

These findings have theoretical implications for the understanding of the role of resilience in promoting psychological health among educators. Practical implications include an empirical contribution to education policy and information that can inform interventions aimed to promote resilience among educators.

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.

Life Satisfaction and Character Strengths in Women With Breast Cancer: Zest and Hope as Predictors

BACKGROUND

Empirical evidence shows that life satisfaction is positively related to character strengths, and although this association has been observed in different populations, it is scarce in breast cancer patients. This study analyzes the relationship between character strengths and life satisfaction in Spanish women diagnosed with breast cancer.

METHODS

A sample of 117 women completed the Satisfaction with Life Scale (SWLS) and the Spanish version of the VIA Inventory of Strengths (VIA-IS). Correlation analysis and regression modeling were performed to determine which strengths predict life satisfaction.

RESULTS

The results of the correlation analysis showed that 15 strengths were positively and significantly associated with life satisfaction, with the highest correlations corresponding to zest, hope, curiosity, social intelligence, love, gratitude, and judgment. Regression modeling indicated that of these, zest and hope were key strengths for predicting life satisfaction.

CONCLUSIONS

These findings suggest that intervention programs based on the development of zest and hope could help to improve life satisfaction and, therefore, the psychological well-being of women with breast cancer.

Physical activity, sleep quality and life satisfaction in adolescents: A cross-sectional survey study

Background

Physical activity, sleep is an important component of adolescents' 24-h movement behavior, and life satisfaction predicts adolescent physical and mental health. However, few studies have explored the relationship between the two variables among Chinese high school students. Consequently, this study aimed to explore the relationship between sleep quality and life satisfaction among Chinese high school students.

Methods

This cross-sectional study was conducted in October 2020 in five high schools in Xuchang City, China. High school students from senior 1 to senior 3 were asked to fill up a questionnaire of demographic characteristics and validated screen instructions for sleep quality (Pittsburgh Sleep Quality Index) and life satisfaction (Satisfaction with Life Scale). The multivariate regression model was applied to explore the association between sleep quality and life satisfaction.

Results

A total of 1127 individuals (51.1% males) participated in this survey, and the prevalence of poor sleep quality was 42.3%. The mean score on the Satisfaction with Life Scale was 16.72 ± 5.67, according to the corresponding scoring criteria, with 15-19 being generally dissatisfied. After controlling for demographic variables, the contribution of subjective sleep quality (β = - 0.181, p < 0.01), sleep duration (β = - 0.080, p < 0.01) and daytime dysfunction (β = - 0.311, p < 0.01) to life satisfaction of high school students increased to 23.2%, indicating that subjective sleep quality, sleep duration, and daytime dysfunction were 22.9% predictive of life satisfaction among high school students. And also, physical activity on schooldays and weekend days were associated with better sleep quality and higher life satisfaction (p < 0.05).

Conclusions

Among Chinese high school students, the prevalence of sleep problems was high, and the majority of students held moderate life satisfaction. Sleep quality was positively correlated with life satisfaction among Chinese high school students, with better sleep quality resulting in higher life satisfaction among students.

General Health and Resilience of Breast Cancer Patients: The Mediator Role of Affective Well-Being

A considerable percentage of breast cancer patients present adequate psychological adjustment and do not become distressed after a breast cancer diagnosis, or, if they do, they manage to recover quickly, which is reflected in their general health. This study aims to determine the role of some psychological mechanisms that affect psycho-oncological adjustment, specifically, resilience and well-being, in a sample of 109 breast cancer patients. For this purpose, participants completed questionnaires on general health, resilience, and well-being (life satisfaction and affect). Correlation analyses and a multiple mediation model were carried out. The results revealed that Pearson correlations between all variables showed strong associations between general health scores and positive and negative affect scores, and moderate associations with life satisfaction and resilience scores. Furthermore; in the mediation model, the total percentage of variance explained by the overall model was 55% (R² = 0.55), where resilience was associated with positive and negative affect, and that influenced general health. These results show that affective well-being is especially relevant in breast cancer patients in terms of its mediating role in resilience, making it clear that an appropriate intervention focused on managing patients' affective status can have a favorable impact on their overall health.

Measurement Invariance and Construct Validity of the Satisfaction With Life Scale (SWLS) in Community Volunteers in Vietnam

Worldwide, the Satisfaction With Life Scale (SWLS) has become the most widely used measure of life satisfaction. Recently, an authorized Vietnamese-language version has been introduced. Using a convenience sample comprising community volunteers from Ho Chi Minh City (N = 1073), confirmatory support was found for the cross-national constancy of the one-dimensional structure underlying the SWLS. Corrected item–total polyserial correlations and Omega coefficient were satisfactory. Using multi-group confirmatory factor analysis, configural, metric, and scalar invariance of the SWLS factorial structure were tested by gender, age, marital status, income, and educational level. Strong evidence of scalar invariance was found for gender and education, on which relevant subgroups did not differ in terms of latent means. Partial scalar invariance was found for marital status (item 4 and 5) and income (item 4). Being involved in an intimate relationship or having a higher income were associated with higher latent means. Scalar invariance in relation to age was very poor. Accordingly, caution must be exerted when comparing age groups. A high SWLS score was predictive of good self-rated health. Implications of the findings are briefly discussed.
