目的：本研究的目的是检查的因素结构的医疗结果研究社会支持调查（MOS-SSS）在低收入，城市照顾者的非裔美国儿童哮喘控制不佳的样本。虽然MOS-SSS是一种常用的措施，社会支持，其心理测量特性还没有被研究，在此population.Methods：验证性因素分析进行，以确定最合适的因素结构的MOS-SSS的照顾者的非裔美国儿童，经常急诊室访问不受控制的哮喘。以下模型进行了测试和比较，使用已建立的拟合统计：一个18项的二阶四因素模型，一个18项的四因素模型，一个双因素模型和一个18项的一因素模型与嵌套models.Results：参与照顾者是单身（75.6%）和女性（97%）。与其他测试模型相比，该量表的18项单因素版本具有最佳拟合统计量：（142）= 308.319，p> 0.001;近似均方根误差（RMSEA）= 0.077; CFI（比较拟合指数）= 0.990; Tucker-Lewis指数（TLI）= 0.988。最终的MOS-SSS模型与照顾者抑郁症状之间存在统计学显著负相关（= − 0.374，p < 0.001），支持结构效度。结论：18项单因素MOS-SSS可能适用于控制不佳的非裔美国儿童照顾者的研究和临床实践。它似乎有希望作为一种机制，以促进了解社会支持和哮喘的结果之间的关系，在这个脆弱的人群。
Objective:The purpose of this study was to examine the factor structure of the Medical Outcomes Study Social Support Survey (MOS-SSS) in a sample of low-income, urban caregivers of African American children with poorly controlled asthma. Although the MOS-SSS is a commonly used measure of social support, its psychometric properties have not been studied in this population.Methods:Confirmatory factor analysis was conducted to determine the most appropriate factor structure for the MOS-SSS in caregivers of African American children with frequent Emergency Department visits for uncontrolled asthma. The following models were tested and compared using established fit statistics: an 18-item second-order four factor model, an 18-item four factor model, a bifactor model and an 18-item one factor model with nested models.Results:Participating caregivers were single (75.6%) and female (97%). An 18-item one factor version of the scale had the best fit statistics compared to the other models tested:(142) = 308.319,p> 0.001; Root mean square error of approximation (RMSEA) = 0.077; CFI (Comparative Fit Index) = 0.990; and Tucker-Lewis Index (TLI) = 0.988. Construct validity was supported by a statistically significant negative relationship between our final MOS-SSS model and caregiver depressive symptoms (= −0.374,p< 0.001).Conclusions:The 18-item one factor MOS-SSS may be appropriate for use in research and clinical practice with caregivers of African American children with poorly controlled asthma. It appears promising as a mechanism to advance understanding of relationships between social support and asthma outcomes in this vulnerable population.
