“…For example, empirical evidence suggests that Japanese people have a different understanding of trust compared with Americans ( Yamagishi and Yamagishi, 1994 ). Researchers have proposed that generalized trust in China may be inflated by the authoritarian political system ( Bjørnskov, 2006 ; Steinhardt, 2012 ). While other Chinese scholars have argued that as Chinese people are tightly connected with family and friends, the feeling of trust of outsiders appears so alien that survey respondents may not include strangers in their interpretation of “most people” ( Tang, 2004 , 2005 ).…”

Generalized Trust and Financial Risk-Taking in China – A Contextual and Individual Analysis

Previous evidence from developed nations has suggested that more trusting individuals are more likely to take financial risks, such as investing in the stock market. Previous studies have found that Chinese citizens have particularly high generalized trust and are more risk-seeking in investment compared with Americans, which makes China an interesting case. The current study examines the relation between generalized trust and stock market participation in China at both a contextual and individual level. Across provinces, a lower level of generalized trust was associated with stock market participation. For example, the stock market participation was four times higher in provinces with the lowest level of perceived fairness than in provinces with the highest level of perceived fairness. The contextual effects of less generalized trust suggest an association between risk-taking behaviors and societal level inequality. At the individual level, trust of strangers was associated with risk preference in highly educated and wealthy people but its effect on risk behaviors was not clear. The findings suggest that trust may affect financial risk-taking behavior at different levels through different pathways, and that cultural differences in understanding of trust also need to be considered.

“…Quality of Life Instruments for Chronic Diseases (QLICD), were developed, including both a generic module (QLICD-GM) [ 14 ], and various modified modules for specific diseases. Instruments have been developed and validated for coronary heart disease (QLICD-CHD) [ 15 ], irritable bowel syndrome (QLICD-IBS) [ 16 ] and for hypertension (QLICD-HY) [ 17 ] but not pulmonary TB, the leading causes of mortality and morbidity of infectious diseases among Chinese. Therefore, we made effort to make the missing piece of the puzzle and develop a set of QLICD, specifically for the Pulmonary TB (QLICD-PT).…”

BackgroundGeneric assessments are less responsive to subtle changes due to specific diseases, making it challenging to fully understand the impact of pulmonary tuberculosis (TB) on patient’s quality of life (QOL).MethodsWe applied programmed decision procedures and theories on instrument development to develop the scale. Two hundred patients with pulmonary TB participated in measuring QOL three times before and after treatments. We assessed the validity, reliability, and responsiveness of QLICD-PT using correlation analysis, factor analysis, multi-trait scaling analysis, randomized block analyses of variance with Least Significant Difference post-hoc tests.ResultsWe composed QLICD-PT with 3 domains (28 items) for general QOL and 1 pulmonary TB specific domain (12 items). Correlation and factor analysis confirmed good structure validity and criterion-related validity when using Chinese version of the Medical Outcomes Short-Form Health Survey (SF-36) as a criterion. The internal consistency of α values were higher than 0.70. The score changes after treatment were of statistical significance for the overall scale, physical domain and specific domain with effect size ranging from 0.32 to 0.72. No floor effects but small ceiling effects were observed at domain level.ConclusionsAs the first pulmonary TB-specific QOL scale developed by a module approach in Chinese, QLICD-PT has an acceptable degree of validity, reliability and responsiveness, and can be used to measure the life quality of PT patients specifically and sufficiently.

“…To the best of our knowledge, no disease-speci c PUD devices have been developed based on a modular approach, let alone a combination of classic test theory (CTT) and generalizability theory (GT).To ll the gaps in QOL research and meet the needs of such research and clinical studies, we developed a set of Quality of Life Instruments for Chronic Diseases (QLICD) through a modular approach [20][21][22][23]. The system includes a general module (QLICD-GM), which can be used for all types of chronic diseases, as well as speci c modules, only for related diseases [20][21][22][23]. For example, the coronary heart disease instrument (QLICD-CHD) is constructed by combining QLICD-GM with the speci c module for coronary heart disease [21].…”

Background: Quality of life (QOL) for patients with Peptic ulcer disease (PUD) is of interest worldwide and disease-specific instruments are needed for clinical research and practice. This paper focus on the development and validation of the PUD scale under the system of Quality of Life Instruments for Chronic Diseases (QLICD-PU) by the modular approach and both classical test theory and Generalizability Theory. Methods: QLICD-PU is developed based on programmatic decision-making procedures, including multiple nominal and focus group discussions, in-depth interviews, and quantitative statistical procedures. Based on the data of 153 PUD inpatients, G and D studies using correlation analysis, factor analysis, t-test, and generalized theoretical analysis were used to assess the validity, reliability, and responsiveness of the scale.Results: When SF-36 was used as the standard, correlation and factor analysis confirmed good structural validity and standard-related validity of QLICD-PU. Except for the social domain (0.62), the internal consistency α of all domains is higher than 0.70. The overall score and the retest reliability coefficients (Pearson r and intra-class correlation ICC) in all domains are higher than 0.80 (0.77 in the social domain). After treatment, the overall scores and scores of all domains have statistically significant changes (P <0.01), except for social impact and sexual function scores. The SRM of field-level scores ranges from 0.34 to 1.03. The G coefficient and reliability index (Ф coefficient) further confirm the reliability of the scale through more accurate variance components and decision-making information about changes in the number of items.Conclusions: QLICD-PU can be used as a useful measurement to assess the quality of life of PUD patients with good psychometric characteristics and multiple advantages.
