Abstract
BACKGROUND Social relationships (SR) is an important domain of health-related quality of life. We developed and calibrated a novel item bank to measure SR in Singapore, a multi-ethnic city in Southeast Asia. METHODS We developed an initial candidate pool of 51 items from focus groups, individual in-depth interviews and existing instruments that had been developed and/or validated for use in Singapore. We administered all items in English to a multi-stage sample of subjects, stratified for age and gender, with and without medical conditions, recruited from community and hospital settings. We calibrated their responses using Samejima's Graded Response Model (SGRM). We evaluated a final 30-item bank with respect to Item Response Theory (IRT) model assumptions, model fit, differential item functioning (DIF), and concurrent and known-groups validity. RESULTS Among 503 participants (47.7% male, 41.4% above 50 years old, 34.0% Chinese, 33.6% Malay and 32.4% Indian), bi-factor model analyses supported essential unidimensionality: explained common variance of the general factor was 0.805 and omega hierarchical was 0.98. Local independence was deemed acceptable: the average absolute residual correlations were < 0.06 and 1.8% of the total item-pair residuals were flagged for local dependence. The overall SGRM model fit was adequate (p = 0.146). Five items exhibited DIF with respect to age, ethnicity and education, but were retained without modification of scores because they measured important aspects of SR. The SR scores correlated in the hypothesized direction with a self-reported measure of global health (Spearman's rho = - 0.28, p < 0.001). CONCLUSION The 30-item SR item bank has shown acceptable psychometric properties. Future studies to evaluate the validity of SR scores when items are administered adaptively are needed.

Rao Y, Xu X, Liu D, Reis C, Newman IM, Qin L, Sharma M, Shen J, Zhao Y. Health-Related Quality of Life in Patients with Arthritis: A Cross-Sectional Survey among Middle-Aged Adults in Chongqing, China. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15040768. [PMID: 29659544 PMCID: PMC5923810 DOI: 10.3390/ijerph15040768] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Revised: 03/29/2018] [Accepted: 04/12/2018] [Indexed: 12/28/2022]
Abstract
Background: Arthritis is a common disease in China, but few studies have been conducted to explore the associated health-related quality of life (HRQoL) and its influencing factors in Chongqing, China. This study aimed to explore the association of arthritis and HRQoL and probe factors affecting HRQoL among arthritis patients. Methods: A cross-sectional survey was conducted in Chongqing, China. A total of 1224 adults were included in the analysis. Medical Outcomes Study Short Form 36 Health Survey (SF-36) was used to measure HRQoL. Multiple linear regression models (stepwise) and covariance analysis models were used to examine the association of arthritis with HRQoL and analyze factors associated with HRQoL among arthritis patients. Results: Participants with arthritis had poorer HRQoL than those without. Among arthritis patients, the female was associated with a poorer state of physical functioning (p < 0.05); unemployed patients had a poorer state of role-physical than employed patients (p < 0.05); low average monthly income was associated with a poorer state of physical functioning (p < 0.01); childhood non-breastfeeding history was associated with a poorer state of social functioning (p < 0.01); average or dissatisfied attitude to current living conditions was associated with a poorer state of vitality and mental health (p < 0.05 for all); moreover, poor or general appetite was associated with a poorer state of role-physical, general health, social functioning, bodily pain, and role-emotional (p < 0.01 for all). Conclusions: Arthritis patients have worse HRQoL than those without in the Chinese population. Female, low socioeconomic status, childhood non-breastfeeding history, average or dissatisfied attitude to current living conditions and poor or general appetite were associated with poorer state of HRQoL among Chinese arthritis patients.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is significantly associated with psychiatric morbidity. Mental health conditions are often unrecognized and untreated in primary care. AIMS To assess prevalence of anxiety and depression and their impact on arthritis pain and functional disability in Slovak patients with rheumatoid arthritis. METHODS Anxiety was assessed by the Beck Anxiety Inventory (BAI), depression by the Zung self-rating depression scale (SDS), pain by the visual analog scale (VAS) and functional disability by the health assessment questionnaire - disability index (HAQ-DI) in 142 patients with rheumatoid arthritis. Spearman's rho was calculated to assess relations between variables. Stepwise linear regression analysis was used to assess impact of anxiety and depression on arthritis pain and functional disability. RESULTS High prevalence of anxiety and depression was observed in arthritis patients. Anxiety and depression were significant predictors of arthritis pain and functional disability. Sex, education, marital status, disease duration and comorbidity had no impact on arthritis pain and functional disability. CONCLUSION These findings support the notions that psychological negative affect can influence subjective perception of arthritis pain and disability. The regular screening of anxiety and depression and the psychological approaches can be useful for managing arthritis patients.
