The Rheumatology Attitudes Index (RAI) was administered to 138 patients with systemic lupus erythematosus (SLE) to determine its reliability and to examine the construct of learned helplessness in patients with this disease. The internal consistency of the RAI was indicated by Cronbach's standardized alpha value (alpha = 0.70). Significant correlations were observed between RAI scores and the Modified Health Assessment Questionnaire Activities of Daily Living difficulty (r = 0.34, P less than or equal to 0.001) and dissatisfaction (r = 0.32, P less than or equal to 0.001) scores, the 10-cm visual analog pain scale (r = 0.42, P less than or equal to 0.001), and the Psychosocial Adjustment to Illness Scale raw total (r = 0.63, P less than or equal to 0.01). These findings support the external validity of the RAI in SLE. In addition, these data suggest that the learned helplessness construct might be relevant to the outcomes of morbidity and mortality in patients with SLE.
对138例系统性红斑狼疮（SLE）患者进行了风湿病态度指数（RAI）测试，以确定其可靠性，并研究该疾病患者的习得性无助结构。RAI的内部一致性通过克朗巴赫标准化α值表示（α = 0.70）。观察到RAI评分与改良健康评估问卷日常生活活动困难程度（r = 0.34，P≤0.001）、不满程度（r = 0.32，P≤0.001）评分、10厘米视觉模拟疼痛量表（r = 0.42，P≤0.001）以及疾病心理社会适应量表原始总分（r = 0.63，P≤0.01）之间存在显著相关性。这些发现支持了RAI在SLE中的外部效度。此外，这些数据表明，习得性无助结构可能与SLE患者的发病和死亡结果相关。
