目标。本项目的目标是开发一个更全面、更敏感的关节炎影响评定量表(AIMS)的版本。修订了AIMS量表条目，增加了3个新的量表，用于评估手臂功能、工作和社会支持。还增加了一些部分，以评估对功能的满意度、将问题归因于关节炎，以及自我指定优先改善的领域。新仪器被命名为AIMS2。对问卷的形式和内容进行了初步检验，并对问卷的信度和效度进行了绩效检验。在一项对24名受试者进行的初步研究中，问卷完成时间平均为23分钟，对工具的长度和完成的容易程度以及受试者填写连续表格并通过邮寄返回的意愿的评价是积极的。对408名受试者进行了测量性能测试：299名类风湿性关节炎(RA)和109名骨性关节炎(OA)；其中45名受试者在3周内完成了第二次AIMS2。12个量表的内部一致性系数RA组为0.72~0.91，OA组为0.74~0.96。重测信度为0.78~0.94。除OA的流动性水平外，所有量表内因素分析都产生了单因素。RA组和OA组的有效性分析表明，患者将某个区域指定为问题或优先改善的区域与该区域较差的AIMS2量表得分显著相关。信度、因素分析和效度结果在年龄、性别和教育程度亚组中一致。满意度与同一健康状况区的功能水平呈中等相关，满意度条目构成了一个可靠的量表。对关节炎归因项目的回答显示，本样本中大部分功能障碍是由于关节炎引起的。AIMS2是一个经过修订和扩展的健康状况问卷，具有出色的测量特性，应该在关节炎临床试验和结果研究中有用。
Objective. The goal of this project was to develop a more comprehensive and sensitive version of the Arthritis Impact Measurement Scales (AIMS).Methods. AIMS scale items were revised, and 3 new scales were added to evaluate arm function, work, and social support. Sections were also added to assess satisfaction with function, attribution of problems to arthritis, and self-designation of priority areas for improvement. The new instrument was designated the AIMS2. A pilot test of format and content and a performance test of reliability and validity were carried out.Results. Questionnaire completion times in a pilot study of 24 subjects averaged 23 minutes, and evaluations were positive regarding the instrument's length and ease of completion, and the subjects' willingness to complete serial forms and return them by mail. Measurement performance was tested in 408 subjects: 299 with rheumatoid arthritis (RA) and 109 with osteoarthritis (OA); 45 of these subjects completed a second AIMS2 within 3 weeks. Internal consistency coefficients for the 12 scales were 0.72-0.91 in the RA group and 0.74-0.96 in the OA group. Test-retest reliability was 0.78-0.94. All within-scale factor analyses produced single factors, except for mobility level in OA. Validity analyses in both the RA and the OA groups showed that patient designation of an area as a problem or as a priority for improvement was significantly associated with a poorer AIMS2 scale score in that area. Reliability, factor analysis, and validity results were consistent in age, sex, and education subgroups. Satisfaction was moderately correlated with level of function in the same health status area, and the satisfaction items formed a reliable scale. Responses to the arthritis attribution items showed that most dysfunction in this sample was due to arthritis.Conclusion. The AIMS2 is a revised and expanded health status questionnaire with excellent measurement properties that should be useful in arthritis clinical trials and in outcomes research.
