Analysing the Simultaneous Relationship Between Life Satisfaction and Health-Related Quality of Life

This paper aims to examine whether life satisfaction and health-related quality of life (HRQoL) are simultaneously related, as well as to quantify the bias that occurs if simultaneity is not accounted for. The study sample consisted of 870 respondents, representative of the Spanish adult general population. Using a simultaneous equations system —with the satisfaction with life scale (SWLS) and the SF-6D index as outcome variables—, we found a simultaneous association between life satisfaction and HRQoL, although this relationship is heterogeneous in individual characteristics such as age and sex. More important, the fact of estimating the relationship between life satisfaction and HRQoL under a unidirectional approach severely underestimates the effect of life satisfaction on HRQoL and, to a lesser degree, the reverse direction effect. In consequence, policy decisions intended to improve satisfaction with life or HRQoL can be wrong if they rely on unidirectional estimates. Another relevant implication of this research is that, as a result of the simultaneous relationship between life satisfaction and HRQoL, not only health interventions may increase satisfaction with life, but also policies that improve life satisfaction can lead to positive side effects on HRQoL.     

Character Strengths and PERMA: Investigating the Relationships of Character Strengths with a Multidimensional Framework of Well-Being

Character strengths are positively valued traits that are expected to contribute to the good life (Peterson and Seligman 2004). Numerous studies have confirmed their robust relationships with subjective or hedonic well-being. Seligman (2011) provided a new framework of well-being suggesting five dimensions that encompass both hedonic and eudemonic aspects of well-being: positive emotions, engagement, positive relationships, meaning and accomplishment (forming the acronym PERMA). However, the role of character strengths has not been studied so far in this framework. Also, most studies on the relationships between character strengths and well-being only have only relied on self-reports. This set of two studies examines the relationships of character strengths and the orientations to well-being in two cross-sectional studies (Study 1: N = 5521), while also taking informant-reports into account and utilizing different questionnaires to control for a possible method bias (Study 2: N = 172). Participants completed validated assessments of character strengths and the PERMA dimensions (self-reports in Study 1, self- and informant-reports in Study 2). Results showed that in self-reports, all strengths were positively related to all PERMA dimensions, but there were differences in the size of the relationships. Accomplishment, for example, showed the strongest associations with strengths such as perspective, persistence, and zest, whereas for positive relationships, strengths such as teamwork, love, and kindness were the best predictors. These findings were largely confirmed by informant-reports in Study 2. The findings provide further support for the notion that character contributes to well-being and they could guide the development of strengths-based interventions tailored to individual needs.

     

Job Autonomy as a Predictor of Mental Well-Being: The Moderating Role of Quality-Competitive Environment

Purpose

This study examines the moderating role of quality-competitive environment on the relationships between job autonomy and employees?? mental well-being and organizational commitment. It also investigates the mediating role of organizational commitment on the relationship between job autonomy and mental well-being.

Design/Methodology/Approach

The proposed hypotheses were tested by hierarchical linear modeling using an archival dataset from the Workplace Employment Relations Survey, which was conducted in Great Britain in 2004 and 2005 (12,836 employees and 1,190 managers).

Findings

This study found that quality-competitive environment moderated the relationships between job autonomy and mental well-being and between job autonomy and organizational commitment. That is, job autonomy was more strongly related to mental well-being and organizational commitment in more quality-competitive organizations. The results also indicated that this moderation was partially mediated by organizational commitment.

Implications

Because job autonomy is related to employees?? mental well-being and organizational commitment, organizations need to provide their employees with job autonomy. More importantly, because these positive relationships are stronger in quality-competitive companies, organizations in a highly quality-competitive market in particular should provide their employees with more job autonomy.

Originality/Value

This is one of the first studies that investigated the vertical fit between job autonomy and organizational contexts while focusing on individual employees?? outcomes (attitudes and mental well-being). The results were obtained by data from a nationally representative sample, allowing us to generalize the results. Additionally, since the dataset was collected from multiple sources, self-report and common-method biases are minimized.     

Religious Practice and Health-Related Quality of Life in Iranian Adolescent Girls

This study aimed to determine the relationship between religious practice and health-related quality of life in adolescent girls in Tabriz, Iran, 2014–2015. This cross-sectional study was conducted on 520 female students who were selected using the random sampling method. Religious practice and health-related quality of life questionnaires were used for data collection. Multivariate linear regression analysis showed a significant relationship between health-related quality of life and received religious support, religiosity, father’s and mother’s education, father’s occupation, family economic status, and the number of children. It is necessary to find ways to further promote religious practices in adolescents and ultimately their quality of life.     

Health-Related Quality of Life in a Low-Socioeconomic Status Public Rental-Flat Population in Singapore

Health-related quality of life (HRQoL) is a well-established measure of health and general well-being. Socioeconomic status (SES) can affect HRQoL. We sought to determine whether there were differences in HRQoL between low versus higher area-SES flat communities in Singapore. Residents in two integrated public housing precincts comprising of rental-flat blocks (low area-SES neighborhood) and neighboring owner-occupied blocks (higher area-SES neighborhood) were asked to rate their self-perceived HRQoL using the EuroQol Group five dimensions (EQ-5D) instrument. The EQ-5D assesses HRQoL in five domains (mobility, self-care, usual activities, anxiety/mood and pain) and with a global visual analogue scale (EQ-VAS). We evaluated differences in HRQoL between the rental and owner-occupied neighborhoods, and factors associated with anxiety/depression in the rental-flat neighborhood using multivariate logistic regression. The participation rate was 89.1% (634/711). In the owner-occupied neighborhood, 56.7% (216/381) were in full health, compared with 54.2% (137/253) in the rental-flat population (OR = 0.90, 95%CI = 0.66–1.24, p = 0.568). Across the five domains, staying in a rental-flat neighborhood was independently associated with anxiety/depression (adjusted odds ratio [aOR] = 1.79, 95%CI = 1.10–2.92, p = 0.019). In the rental-flat population, having anxiety/depression was independently associated with minority ethnicity, problems with self –care, pain/discomfort, difficulty with healthcare costs, and not being on subsidized primary care (p < 0.05). There was no significant difference on the EQ-VAS between the two neighborhoods (p = 0.627). Staying in a low area-SES neighborhood was associated with more mental health problems. In the rental-flat population, self-reported anxiety/depression was associated with minority ethnicity, physical health problems, and financial disadvantage in healthcare.     

An Exercise Program Improves Health-Related Quality of Life of Workers

Low back problems are associated with decreased quality of life. Specific exercises can improve quality of life, resulting in better professional performance and functionality. The purpose of this study was to evaluate the effect of following a 21-month exercise program on the quality of life of warehouse workers. The population included 557 male warehouse workers from a food distribution company in Oporto, Portugal. Upon application of the selection criteria, 249 workers were deemed eligible, which were randomized into two groups (125 in the intervention group and 124 in the control group). Then, subjects were asked to volunteer for the study, the sample being formed by 229 workers (112 in the intervention group and 117 in the control group). All subjects completed the SF-36 questionnaire prior to beginning the program and on the 11th and 21st months following it. The exercises were executed in the company facilities once a day for 8?min. Data were analyzed using SPSS? 17.0 for Windows?. After 11?months of following the exercise program, there was an increase in all scores for the experimental group, with statistically significant differences in the dimensions physical functioning (0.019), bodily pain (0.010), general health (0.004), and rolephysical (0.037). The results obtained at the end of the study (21?months) showed significant improvements in the dimensions physical functioning (p?=?0.002), rolephysical (p?=?0.007), bodily pain (p?=?0.001), social functioning (p?=?0.015), role-emotional (p?=?0.011), and mental health (p?=?0.001). In the control group all dimensions showed a decrease in mean scores. It can be concluded that the implementation of a low back specific exercise program has changed positively the quality of life of warehouse workers.

Measuring Health-Related Quality of Life After Stroke: A Brief Tool

Routine assessment of health-related quality of life (HRQoL) can be time consuming and burdensome for a person with stroke. Therefore the aim of this study was to develop and test a brief instrument for assessing HRQoL among people with stroke. The Quality of Life after Stroke Scale (QLASS) was constructed from items within the Quality of Life Index-Stroke Version and the Chronic Respiratory Disease Questionnaire. It was administered to 92 people with stroke at three points in time: immediately after discharge from hospital, 6 months and 12 months later. Results suggest that the QLASS has 19 items which represent three factors: emotional functioning, mastery and fatigue which correlate with valid measures of health status and activities of daily living. The QLASS is proposed as a brief, valid HRQoL tool for use among people with stroke.     

Perceived Quality of Life and Health-Related Correlates Among Men Aboard Navy Ships

The objectives of this study are twofold: First, findings are presented to provide a baseline assessment of perceived quality of life (QOL) in a group of 430 Navy shipboard men. As part of this objective, Navy shipboard QOL ratings are compared with those of a U.S. national sample to provide a perspective for interpreting Navy responses. Second, the study identifies health-related factors associated with QOL. In both the Navy and national samples, QOL evaluations are generally positive and show considerable variation. Navy shipboard QOL evaluations are higher than civilian evalua- tions on items addressing satisfaction with self and the ability to adjust to changes, but lower on items assessing satisfaction with work and personal life. A consistent association exists between better health/fitness and higher QOL, including satisfaction with one's Navy job. Consistent correlates of perceived QOL are self-ratings of health and physical fitness, perceptions of not being overweight, and lower reporting of psychosomatic symptoms.     

Sociodemographic and Lifestyle Correlates of Health-Related Quality of Life in Croatian University Students

The purpose of this study was to assess the health-related quality of life (HRQoL) in a sample of Croatian university students and to determine its association with sociodemographic and lifestyle characteristics. The study was conducted on a random sample of 1750 students in Zagreb, Croatia. We used the 12-item Short-Form Health Survey (SF-12v2) and separate questions on sex, age, body mass index (BMI), settlement size, disposable income, cigarette consumption, alcohol consumption, and exercise frequency. The HRQoL scale on which Croatian students scored the highest was Physical Functioning. High mean scores were also found for other physical health measures, while the scores in mental health scales were somewhat lower. Male students scored significantly higher than females on all SF-12 scales (p?<?0.05). The regression analysis showed that Physical Component Summary score (PCS) is negatively related to BMI (partial r?=??0.09) and cigarette consumption (partial r?=??0.06), and positively related to alcohol consumption and exercise frequency (partial r?=?0.08, for both), while Mental Component Summary score (MSC) is positively related to BMI (partial r?=?0.07) and exercise frequency (partial r?=?0.10). Although HRQoL-scores for the Croatian students were higher than in the general population of Croatia and student populations in several other countries, there is still room for improvement, especially in the mental health aspect. In general, HRQoL was found to be significantly lower among females and smokers, but positively related with exercise frequency. In order to improve students’ HRQoL, university authorities should consider initiating health-promotion programs with emphasis on females, smokers and non-exercisers.     

Predictors of Health-Related Quality of Life in Iranian Women of Reproductive Age

Introduction

Quality of life, one of the major concerns of health professionals, is the main indicator for measuring health status. The present study aimed to assess the quality of life and its predictors in women of reproductive age in Tabriz (Iran).

Methods & Materials

This cross-sectional study was conducted on 532 married women of reproductive age using a two-stage cluster random sampling method. A self-administered questionnaire was used for data collection. It included questions on demographic characteristics, quality of life (SF-36), female sexual function index (FSFI), and ENRICH marital satisfaction. The general linear model in SPSS-13 was used to determine the predictors of quality of life.

Results

The mean (standard deviation, SD) score of physical and mental health was 62.2 (17.1) and 60.3 (18.5), respectively (from an attainable score range of 0–100). The highest mean (SD) score [69.5 (25.7)] was obtained for “physical functioning,” while the lowest [52.9 (24.4)] was for “role limitations due to emotional problems.” There was a significant positive correlation between the quality of life and its sub-domains with sexual function (r?=?0.15–0.33) and marital satisfaction (r?=?0.15 to 0.49). Higher sexual function and marital satisfaction, higher educational level, and no prior history of depression were predictors of physical and mental components of health-related quality of life.

Conclusion

Physical and mental components of quality of life among women were moderate. Relieving sexual problems and dysfunction and improving marital satisfaction may improve women's quality of life and help to achieve a strong family life.

     

Optimism and Hope After Multiple Disasters: Relationships to Health-Related Quality of Life

Natural and technological disasters are devastating events for individuals and communities. The authors examined the role of optimism and hope in predicting health indicators in a sample of disaster survivors who were exposed to Hurricanes Katrina and Rita in 2005. Participants were noncoastal residents, current coastal residents, and current coastal fishers who were also economically impacted by the 2010 BP Deepwater Horizon oil spill. All participants completed measures of optimism, hope, and the SF-36 Health Survey, which provides summary scores for mental and physical health. Logistic regressions indicated that optimism and hope were independently and positively associated with better mental health (OR = 1.21; 95% CI: 1.10, 1.32 and OR = 1.11; 95% CI: 1.05, 1.17 respectively). Neither optimism nor hope were significantly associated with physical health when considered alone. However, optimism interacted with prior lifetime trauma, where optimism only significantly predicted physical health for those with higher previous trauma scores. These results provide new evidence of optimism and hope as protective factors that may positively impact mental health after multiple disasters.     

Impaired Health-Related Quality of Life in Children and Families Affected by Methylmalonic Acidemia

An understanding of health related quality of life (HRQoL) in children and families affected by methylmalonic acidemia (MMA) is important in planning counseling and therapeutic intervention. Liver transplantation (LT) is used as a treatment for MMA; however, its risks and benefits continue to be investigated. The purpose of this study was twofold: (1) to measure HRQoL in children and families affected by MMA using the Pediatric Quality of Life Inventory (PedsQL?) parent version, and (2) to assess the impact of LT on HRQoL by comparing LT and non-LT patient scores and free responses. Parents/caregivers reported lower scores on the majority of the PedsQL? scales as compared to samples of healthy children, children with solid organ transplants for indications other than MMA, and families affected by chronic conditions. Scores for children with MMA were lowest in school and social functioning and scores for families were lowest in worry and activity impairment. There were no significant differences in LT and non-LT patient scores on the PedsQL? scales. Our results document the negative impact of MMA on HRQoL.     

Methods for Assessing Quality of Life and Well-Being in Frail Older People

The appropriateness, reliability and convergence of differing methods and associated instruments for the assessment of quality of life and well-being in frail older people was examined in 60 ( S 65 years of age) nursing home residents. The feasibility of measuring quality of life and well-being via a variety of instruments was explored through observation (an adaptation of Dementia Care Mapping), structured interview (Schedule for the Evaluation of Individual Quality of Life - Direct Weighting), and proxy questionnaire (Pleasant Events Schedule - Alzheimer Disease; Apparent Emotion Rating Scale). The observational assessment and Pleasant Events Schedule demonstrated good reliability. Significant associations were found between well-being as assessed by observation, and active social interaction and engagement in recreation as assessed by observation, quality of life as assessed by structured interview, and enjoyment of activities as assessed by proxy questionnaire. These findings indicate the importance of social activity in later life, and the potential of different approaches for the appropriate assessment of key aspects of quality of life in frail older people.
