To evaluate the psychometric properties of the Chinese Mandarin version of the Medical Outcomes Study Social Support Survey (MOS-SSS-CM) in patients with coronary heart disease (CHD) in mainland China.
Measurement performance of the MOS-SSS-CM was tested on a convenience sample of 200 Chinese patients with CHD in a University-affiliated hospital in Xi'an, P. R. China. To establish reliability of the instrument, 40 patients were retested 2 weeks later through telephone interview. The traditional Chinese version of the MOS-SSS was transformed into a simplified Chinese Mandarin version and administered to participants, together with Chinese Mandarin versions of the Short Form-36 item Health Survey (SF-36) and the Hospital Anxiety and Depression Scale (HADS).
The MOS-SSS-CM had acceptable internal consistency with Cronbach α coefficients of 0.91 for the overall scale and 0.71-0.84 for the four subscales. The high correlation (r = 0.56-0.87) between items and the remainder of the scale provides further evidence of internal consistency. The test-retest reliability was generally acceptable with intraclass correlation coefficients of 0.89 for the overall scale and 0.74-0.88 for the four subscales. There was acceptable concurrent validity with moderate significant correlations (r ≥ 0.3, p < 0.01) between the MOS-SSS-CM and the Chinese Mandarin version of the HADS. Confirmatory factor analysis supported a four-factor structure of the MOS-SSS-CM measuring the self-perceived adequacy of functional support of Chinese patients with CHD.
The MOS-SSS-CM is a valid and reliable measure for Chinese Mandarin-speaking patients with CHD.
评估中文简体版医学结局研究社会支持量表（MOS-SSS-CM）在中国大陆冠心病（CHD）患者中的心理测量学特性。
在西安一所大学附属医院的便利样本中，对 200 名中国 CHD 患者进行了 MOS-SSS-CM 的测量性能测试。为了确定该工具的可靠性，通过电话访谈对 40 名患者进行了 2 周后的重测。将传统的 MOS-SSS 中文版本转化为简体中文普通话版本，并与中文简体版的健康调查短表 36 项（SF-36）和医院焦虑抑郁量表（HADS）一起提供给参与者。
MOS-SSS-CM 具有可接受的内部一致性，总量表的 Cronbach α 系数为 0.91，四个分量表的 Cronbach α 系数为 0.71-0.84。项目与量表其余部分之间的高相关性（r=0.56-0.87）提供了进一步的内部一致性证据。测试-重测信度通常是可以接受的，总量表的组内相关系数为 0.89，四个分量表的组内相关系数为 0.74-0.88。MOS-SSS-CM 与中文简体版 HADS 之间存在可接受的同时效度，中度显著相关（r≥0.3，p<0.01）。验证性因子分析支持 MOS-SSS-CM 具有四个因素结构，用于测量中国 CHD 患者自我感知的功能支持充足性。
MOS-SSS-CM 是一种适用于讲中文简体的冠心病患者的有效且可靠的测量工具。
