Present the psychometric results of the Living with Osteoarthritis (LW-OA) in Spanish population.
Observational, cross-sectional and multicenter study, with retest on a fraction of the sample.
Public and private centres of primary and secondary healthcare, as well as patient associations from Navarra, La Rioja, Madrid, Valencia and Malaga.
The sample was composed by 291 patients with OA with a medical diagnosis in every stage of the disease from primary or secondary healthcare, Spanish nationality and not hospitalized.
In addition to LW-OA, a sociodemographic questionnaire was included, as well as scales to evaluate social support perceived from the patient (DUFSS), quality of life (WHOQOL-BREF) and satisfaction with life.
Psychometric properties of the LW-OA were measured, as viability and acceptability, reliability (internal consistency and reproducibility), precision and construct validity (convergent, internal and known-groups).
100% of the data were computable. Excellent data quality was obtained. Cronbach's alpha for the scale total was 0.87 and the homogeneity index 0.22. ICC for the scale total was 0.88. As for precision, the SEM was 5.18 (<½DE=7.47).
The LW-OA is a valid and feasible measure to evaluate the process of living with OA in Spain.
展示西班牙人群骨关节炎生活量表（LW-OA）的心理测量结果。
观察性、横断面多中心研究，对部分样本进行重测。
公立和私立的初级及二级医疗保健中心，以及来自纳瓦拉、拉里奥哈、马德里、巴伦西亚和马拉加的患者协会。
样本由291例骨关节炎患者组成，这些患者来自初级或二级医疗保健机构，处于疾病的各个阶段，具有西班牙国籍且未住院。
除了LW-OA外，还纳入了一份社会人口学问卷，以及用于评估患者感知到的社会支持（DUFSS）、生活质量（WHOQOL-BREF）和生活满意度的量表。
测量LW-OA的心理测量特性，如可行性和可接受性、信度（内部一致性和可重复性）、精度和结构效度（收敛效度、内部效度和已知组效度）。
100%的数据可计算。获得了优异的数据质量。量表总分的克朗巴哈系数为0.87，同质性指数为0.22。量表总分的组内相关系数为0.88。至于精度，标准误为5.18（<½DE=7.47）。
LW-OA是评估西班牙骨关节炎患者生活过程的一种有效且可行的测量工具。
