High quality self-care among individuals with chronic obstructive pulmonary disease (COPD) promotes better outcomes, however, there are few validated self-care measures that are psychometrically sound to be used in research.
The purpose of this study is to examine the psychometric properties of the Self-Care in Chronic Obstructive Pulmonary Disease Inventory (SC-COPDI) in an English-speaking population in the United States.
Factorial validity, construct validity and reliability of the SCCOPDI were examined using components analysis via principal components analysis, hypothesis testing via multivariate linear regression, Cronbach's alpha, and split-half reliability.
The SCCOPDI demonstrated strong evidence of validity and reliability on par with the SCCOPDI's original construction. Component analysis produced item loadings consistent with the theoretical underpinnings of the instrument. Reliability metrics yielded good internal consistency across all subscales of the SCCOPDI.
The SCCOPDI is a valid and reliable instrument to measure self-care in people with COPD.
慢性阻塞性肺疾病（COPD）患者的高质量自我护理可促进更好的治疗效果，然而，在研究中很少有经过验证且心理测量学上合理的自我护理测量方法。
本研究旨在检验慢性阻塞性肺疾病自我护理量表（SC-COPDI）在美国说英语人群中的心理测量特性。
通过主成分分析进行成分分析、通过多元线性回归进行假设检验、计算Cronbach's α系数以及分半信度，来检验SC-COPDI的因子效度、结构效度和信度。
SC-COPDI表现出与原始编制时相当的有效性和可靠性的有力证据。成分分析得出的项目负荷与该工具的理论基础一致。信度指标在SC-COPDI的所有子量表中产生了良好的内部一致性。
SC-COPDI是一种有效且可靠的工具，用于测量COPD患者的自我护理情况。
