The need for reliable, valid tools to measure patient-reported outcomes (PROs) is critical both for research and for evaluating treatment effects in practice. The Patient-Reported Outcomes Measurement Information System Fatigue-Short Form v1.0-Fatigue 7a (PROMIS F-SF) has had limited psychometric evaluation in various populations.
The aim of the study is to examine psychometric properties of PROMIS F-SF item responses across various populations.
Data from five studies with common data elements were used in this secondary analysis. Samples from patients with fibromyalgia, sickle cell disease, cardiometabolic risk, pregnancy, and healthy controls were used. Reliability was estimated using Cronbach's alpha. Dimensionality was evaluated with confirmatory factor analysis. Concurrent validity was evaluated by examining Pearson's correlations between scores from the PROMIS F-SF, the Multidimensional Fatigue Symptom Inventory-Short Form, and the Brief Fatigue Inventory. Discriminant validity was evaluated by examining Pearson's correlations between scores on the PROMIS F-SF and measures of stress and depressive symptoms. Known groups validity was assessed by comparing PROMIS F-SF scores in the clinical samples to healthy controls.
Reliability of PROMIS F-SF scores was adequate across samples, ranging from .72 in the pregnancy sample to .88 in healthy controls. Unidimensionality was supported in each sample. Concurrent validity was strong; across the groups, correlations with scores on the Multidimensional Fatigue Symptom Inventory-Short Form and Brief Fatigue Inventory ranged from .60 to .85. Correlations of the PROMIS F-SF with measures of stress and depressive mood were moderate to strong, ranging from .37 to .64. PROMIS F-SF scores were significantly higher in clinical samples compared to healthy controls.
Reliability and validity of the PROMIS F-SF were acceptable. The PROMIS F-SF is a suitable measure of fatigue across the four diverse clinical populations included in the analysis.
对于研究以及在实践中评估治疗效果而言，需要可靠、有效的工具来测量患者报告结局（PROs）至关重要。患者报告结局测量信息系统疲劳简表v1.0 - 疲劳7a（PROMIS F - SF）在不同人群中的心理测量学评估有限。
本研究旨在检验PROMIS F - SF项目反应在不同人群中的心理测量学特性。
五项具有共同数据元素的研究数据用于本次二次分析。使用了来自纤维肌痛患者、镰状细胞病患者、心脏代谢风险人群、孕妇以及健康对照的样本。使用克朗巴哈系数估计信度。通过验证性因子分析评估维度性。通过检查PROMIS F - SF得分与多维疲劳症状量表简表及简明疲劳量表得分之间的皮尔逊相关性来评估同时效度。通过检查PROMIS F - SF得分与压力及抑郁症状测量指标之间的皮尔逊相关性来评估区分效度。通过比较临床样本与健康对照的PROMIS F - SF得分来评估已知群体效度。
PROMIS F - SF得分在各样本中的信度充足，从孕妇样本中的0.72到健康对照中的0.88不等。每个样本均支持单维度性。同时效度较强；在各群体中，与多维疲劳症状量表简表及简明疲劳量表得分的相关性在0.60至0.85之间。PROMIS F - SF与压力及抑郁情绪测量指标的相关性为中度至高度，在0.37至0.64之间。与健康对照相比，临床样本中的PROMIS F - SF得分显著更高。
PROMIS F - SF的信度和效度是可接受的。PROMIS F - SF是分析中所纳入的四种不同临床人群疲劳程度的合适测量指标。
