Currently, information on the psychometric properties of the Medical outcomes study-social support survey (MOS-SSS) for patients with chronic disease in primary health care, suggests problems in the dimensionality, specifically predominant unidimensionality in a multidimensional measure. The aim of this study was to determine the internal structure (dimensionality, measurement invariance and reliability) and association with other variables.
A total of 470 patients with chronic disease from a Family Medicine Unit at the Instituto Mexicano del Seguro Social, IMSS, with a mean age of 51.51 years were included. Participants responded to the Questionnaire of Sociodemographic Variables (Q-SV), SF-36 Health-Related Quality of Life Scale-version 1.1, and MOS-SSS.
Non-parametric (Mokken scaling analysis) and parametric (confirmatory factor analysis) analyses indicated unidimensionality, and three-factor model was not representative. A new 8-item version (MOS-S) was developed, where measurement invariance, equivalence with the long version, reliability, and relationship with the SF-36 were satisfactory.
The MOS-SSS scale is unidimensional, and the shortened version yields valid and reliable scores for measuring social support in patients with chronic disease at the primary health care.
目前，关于初级卫生保健中慢性病患者的医学结局研究社会支持调查（MOS - SSS）心理测量特性的信息表明，该量表在维度方面存在问题，尤其是在多维测量中主要呈现单维性。本研究的目的是确定其内部结构（维度、测量不变性和信度）以及与其他变量的关联。
纳入了墨西哥社会保障局（IMSS）一家家庭医学单位的470例慢性病患者，平均年龄为51.51岁。参与者回答了社会人口学变量问卷（Q - SV）、SF - 36健康相关生活质量量表第1.1版以及MOS - SSS。
非参数分析（莫肯量表分析）和参数分析（验证性因子分析）均表明该量表具有单维性，三因素模型不具有代表性。开发了一个新的8项版本（MOS - S），其测量不变性、与长版本的等效性、信度以及与SF - 36的关系均令人满意。
MOS - SSS量表是单维的，缩短版在初级卫生保健中为测量慢性病患者的社会支持提供了有效且可靠的分数。
