Objective: The aim of this study was to develop a new and shorter Chinese version of Ryff’s psychological well-being scale. Design: Cross-sectional survey. Setting: In recent years there have been several versions of this scale, including 84-item, 54-item and 18-item versions. Researchers in different countries have built on Ryff’s version to create their own versions in various languages. However, most versions have not yielded improved confirmatory factor analysis results. Shorter versions of the scale in the past were also less reliable in terms of internal consistency. Method: This study used a sample of 820 middle-aged and older people from Taiwan with an average age of 59.8 years. We used structural equation modelling (SEM) to select items for inclusion. Results: After item selection, a new version of 18 items based on Ryff’s 84-item version was established with improved confirmatory factor analysis validity and reliability. The results for this 18-item version indicated that factor loadings were at least .60, and the reliability alpha coefficients were 0.92 and 0.60–0.75 for its six subscales. Additionally, a significant correlation with the Geriatric Depression Scale (GDS)-15 and quality of life criteria indicate very acceptable criterion-related validities. Conclusion: The 18-item Chinese version does not include any reversely worded items after the item selection processes, thus reducing method artefacts. It also exhibited very acceptable confirmatory factor analysis results.

This study aimed to investigate level of work ability and quality of life (QOL) as well as the relationship between them among patients suffering from work-related musculoskeletal disorders (WMSDs) in Taiwan. A cross-sectional study design with continuous sampling and a questionnaire were used to obtain the research data. Controlling for personal characteristics, pain, psychological distress, and social support, multiple linear regressions were adopted to explore the relationship between work ability and overall QOL. Further analyses were also made to clarify the relationships between work ability and each domain of QOL. In total, 165 patients with WMSDs were recruited. Compared with general workers, the participants reported a lower level of work ability and overall QOL. Work ability was significantly associated with overall QOL when covariates were controlled. Among the four domains of QOL, work ability was significantly associated with both the physical and psychological domains. The conclusion was that work ability is a definite factor of QOL for patients with WMSDs; the essence of work ability may be beyond economic function or social support. Strategies to help workers with WMSDs enhance their work ability to fit their new or temporary jobs would be beneficial to their QOL.

Background: Because of the increasing 5-year survival rate of breast cancer, adjustment to breast cancer survivorship is pertinent to the patient's life after diagnosis. Despite the psychological changes occurring during the transitional period (first 5 years after diagnosis) and after primary therapy having a known, critical effect on survivorship status, the data related to this topic are very limited. Purpose: This study was designed to examine the relationships among demoralization, stress, sleep disturbance, and psychological well-being in women with breast cancer after primary therapy. Methods: Two hundred eight women with breast cancer (mean age = 51.96 ± 8.27) participated in a cross-sectional study in central Taiwan. Recruitment was conducted using convenience snowball sampling at a local teaching hospital. All of the participants had completed primary therapy and were in the 5-year postdiagnosis period. The average duration of cancer was 28 months. The participants completed the Stress of Breast Cancer after Primary Therapy Scale, Demoralization Scale, Pittsburgh Sleep Quality Inventory, and Ryff's Psychological Well-Being Scale–Short Form. Data were analyzed using a structural equation model to find plausible path relationships among stress, demoralization, sleep disturbances, and psychological well-being. Results: Demoralization was shown to completely mediate the effect of stress on sleep disturbances. In addition, the predictive effect of sleep disturbances on psychological well-being was overwhelmingly explained by demoralization when competing with sleep disturbances. Furthermore, a positive path was found between stress and psychological well-being because of the suppression effect of demoralization. Conclusions/Implications for Practice: Demoralization was found to be a mediator that suppressed the relationships among stress, sleep disturbances, and psychological well-being in the adaptation process of patients with breast cancer after primary therapy. This article adds to the limited research on women with breast cancer after primary therapy who are in their initial 5 years of diagnosis. In addition, this study used structural equation model to find the plausible path relationships among the psychological factors involved in the well-being of women with breast cancer. Supporting patients with cancer and effectively reducing their perceived demoralization will be key to transforming stress into personal growth and a facilitator of long-term recovery.

This study aimed to investigate (1) relations of smoking and alcohol to metabolic syndrome (MetS) and its components, with nutrition and exercise controlled; and (2) interactions between smoking/alcohol and nutrition/exercise on MetS. This cross-sectional study enrolled 4025 workers. Self-reported lifestyles, anthropometric values, blood pressure (BP), and biochemical determinations were obtained. Among males, smoking significantly increased the risk of low high-density lipoprotein cholesterol (HDL-C), high triglyceride, abdominal obesity (AO), and MetS. Additionally, smoking showed significant interaction effects with nutrition on high BP, AO, and MetS; after further analysis, nutrition did not decrease above-mentioned risks for smokers. However, there was no significant interaction of smoking with exercise on any metabolic parameter. Alcohol increased the risk of AO, but decreased low HDL-C. It also showed an interaction effect with exercise on AO; after further analysis, exercise decreased AO risk for drinkers. Among females, alcohol significantly decreased the risk of high fasting blood glucose, but did not show significant interaction with nutrition/exercise on any metabolic parameter. In conclusion, in males, smoking retained significant associations with MetS and its components, even considering benefits of nutrition; exercise kept predominance on lipid parameters regardless of smoking status. Alcohol showed inconsistencies on metabolic parameters for both genders.
