Abstract

Social support is a significant protective factor for health and well-being of people with chronic health conditions and disabilities. It is important to include a psychometrically sound measure of social support in their clinical assessment practices, especially during the COVID-19 pandemic. The purpose of this study was to validate the Patient-Reported Outcomes Measurement Information System (PROMIS) Social Support Scale in a sample of people with chronic health conditions and disabilities. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to examine and validate the three-factor measurement structure of the PROMIS Social Support Scale. Exploratory factor analysis and CFA results confirmed that a three-factor measurement structure (instrumental, informational, and emotional support) accounted for 82.75% of the total variance. All items loaded highly onto their respective factors (ranging from .73 to .99). Reliability coefficients of the three subscales ranged from .95 to .97. The three social support factors were positively associated with community participation and subjective well-being in the theoretically expected directions. Findings of this study provide strong empirical support for the psychometric properties of the PROMIS Social Support Scale and its use with people with chronic health conditions and disabilities in clinical practice and research.

在慢性病患者和残疾人样本中对 PROMIS 社会支持量表进行心理计量验证：因子分析研究

社会支持是慢性病患者和残疾人健康和幸福的重要保护因素。在临床评估实践中，尤其是在 COVID-19 大流行期间，将心理计量学上可靠的社会支持度量纳入其中非常重要。本研究的目的是在慢性病患者和残障人士样本中验证患者报告结果测量信息系统（PROMIS）社会支持量表。通过探索性因子分析（EFA）和确证性因子分析（CFA），研究并验证了 PROMIS 社会支持量表的三因子测量结构。探索性因子分析和确证性因子分析结果证实，三因子测量结构（工具支持、信息支持和情感支持）占总方差的 82.75%。所有项目在各自因子上的负荷量都很高（从 0.73 到 0.99 不等）。三个分量表的信度系数介于 0.95 和 0.97 之间。三个社会支持因子与社区参与和主观幸福感呈正相关，符合理论预期方向。本研究的结果为 PROMIS 社会支持量表的心理测量特性及其在临床实践和研究中用于慢性病患者和残障人士提供了强有力的实证支持。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
