目的：本研究旨在探讨社会供给量表（SPS）的因素和结构效度的人与多发性硬化症（MS）的样本。方法：参与者包括292名MS患者（83.9%为女性），这些患者是从国家多发性硬化症协会的大伊利诺伊州、盖特威州和印第安纳州分会招募的。参与者完成了SPS和疼痛、疲劳、抑郁、焦虑、MS自我效能、生活质量和生活满意度测量。使用验证性因素分析（CFA）进行因素效度测试，并根据相关措施的分数双变量相关的强度进行结构效度检查。结果如下：验证性因素分析的结果表明，一阶6因素测量模型提供了一个很好的拟合的24个项目的SPS（CFI = 0.94，TLI = 0.93，RMSEA = 0.07）和6个因素可以描述为一个单一的，二阶因素的整体社会供应（CFI = 0.93，TLI = 0.92，RMSEA = 0.08）。总体评分的Cronbach α为0.89，6个分量表的α介于0.66和0.81之间。SPS总体和子量表得分与生活满意度、抑郁、焦虑、MS自我效能感和生活质量指标显著相关。结论：本研究的结果支持社会供给量表的因素效度、结构效度和信度，并将其用于MS患者的社会供给测量。影响和意义本研究首次在MS患者样本中检验了社会供给量表（SPS）的因素效度。结果支持SPS的6个因素结构，即依恋、社会融合、价值保证、可靠的联盟，指导和机会的养育，并表明社会支持可以概念化为双向的性质，即个人感知和提供支持。调查结果还提供了证据的SPS的MS患者的结构效度。临床医生可以使用SPS作为MS患者的筛选工具，以评估特定的社会支持需求和能力。
Objective: This study examined the factorial and construct validity of the Social Provisions Scale (SPS) in a sample of people with multiple sclerosis (MS). Method: Participants included 292 individuals with MS (83.9% women) recruited from the Greater Illinois, Gateway, and Indiana chapters of the National Multiple Sclerosis Society. Participants completed the SPS and pain, fatigue, depression, anxiety, MS self-efficacy, quality of life, and satisfaction with life measures. Factorial validity was tested using confirmatory factor analysis (CFA), and construct validity was examined based on the strength of bivariate correlations with scores on related measures. Results: Findings from the CFA indicated that a first-order, 6-factor measurement model provided a good fit for the 24 items of the SPS (CFI = .94, TLI = .93, RMSEA = 0.07) and that the 6 factors could be described by a single, second-order factor of the overall social provisions (CFI = .93, TLI = .92, RMSEA = 0.08). Cronbach's alpha was .89 for the global score and between .66 and .81 for the 6 subscales. The SPS global and subscale scores correlated significantly with satisfaction with life, depression, anxiety, MS self-efficacy, and quality of life measures. Conclusions: Findings from this study support the factorial validity, construct validity, and reliability of the SPS as a measure of social provisions for use with people with MS.Impact and ImplicationsThis study was the first to examine the factorial validity of the Social Provisions Scale (SPS) in a sample of people with MS. Results support the 6-factor structure of the SPS, namely attachment, social integration, reassurance of worth, reliable alliance, guidance, and opportunity for nurturance, and demonstrate that social support can be conceptualized as bidirectional in nature-that is, individuals perceive and provide support. Findings also provide evidence for the construct validity of the SPS for people with MS. Clinicians can use the SPS as a screening tool for people with MS to assess specific social support needs and capabilities.
