为类风湿性关节炎（RA）患者制定并验证有价值生活活动残疾和适应量表（VLA）的简化版本。为了缩短现有的VLA措施，项目反应理论分析进行了使用数据从449例RA患者。接下来，对20例RA患者进行结构化访谈，评价VLA量表（S-VLA）的14项缩短版本。最后，对150例RA患者进行了S-VLA沿着其他措施，包括健康评估问卷（HAQ）和SF-36。两周后随机抽取50名患者完成S-VLA，以评估可靠性。计算项目统计量以评估单个项目与S-VLA总分之间的相关性。S-VLA和其他测量之间的相关性被用来评估效度。重测信度为0.91，而Cronbach的α为S-VLA为0.95。当省略时，14个项目中没有一个与改善的α系数相关。所有项目均与S-VLA总分密切相关。S-VLA评分与HAQ（r=0.81; p≤0.001）、患者报告的疾病活动（r=0.71; p≤0.001）、能力满意度（r=0.82; p≤0.001）和活动受限天数（r=0.65; p≤0.001）高度正相关。此外，正如假设的那样，S-VLA与SF-36身体健康总评（r=−0.78; p≤0.001）和子量表：身体功能（r=−0.80; p≤0.001）、身体角色（r=−0.67; p≤0.001）和社会功能（r=−0.72; p≤0.001）呈负相关。S-VLA是一个简短，有效，可靠的工具，可能被证明是有用的监测残疾人与RA。
Develop and validate a shortened version of the Valued Life Activities disability and accommodations scale (VLA) for individuals with rheumatoid arthritis (RA). To shorten the existing VLA measure, item response theory analyses were conducted using data from 449 patients with RA. Next, the resulting 14-item shortened version of the VLA scale (S-VLA) was evaluated by structured interviews among 20 RA patients. Lastly, the S-VLA was administered to 150 RA patients along with other measures including the Health Assessment Questionnaire (HAQ) and SF-36. A random sample of 50 patients completed the S-VLA two weeks later to assess reliability. Item statistics were calculated to evaluate correlations between individual items and S-VLA total score. Correlations between the S-VLA and other measures were used to evaluate validity. Test–retest reliability was 0.91, while Cronbach’s alpha for the S-VLA was 0.95. None of the 14 items were associated with improved alpha coefficients when omitted. All items were strongly correlated with the S-VLA total score. S-VLA scores were highly positively correlated with HAQ (r=0.81; p≤0.001), patient-reported disease activity (r=0.71; p≤0.001), satisfaction with abilities (r=0.82; p≤0.001), and number of days with activity limitations (r=0.65; p≤0.001). In addition, as hypothesized, the S-VLA was inversely correlated with SF-36 Physical Component Summary score (r=−0.78; p≤0.001) and subscales: Physical Functioning (r=−0.80; p≤0.001), Role Physical (r=−0.67; p≤0.001) and Social Functioning (r=−0.72; p≤0.001). The S-VLA is a short, valid, and reliable instrument that may prove useful for monitoring disability among individuals with RA.
