目的：构建适合我国老年人群肌少症全面评估量表（包括自评与他评2个部分）的初始量表。方法：通过检索和复习文献,选取与肌少症相关的量表,形成初步条目池后,经国内16名相关领域的专家2轮德尔菲咨询问卷筛选条目,通过统计专家积极系数、专家权威程度、专家意见重要性的协调系数、各指标得分平均值、变异系数和满分率,形成老年人肌少症评估初始量表。结果：经文献收集及专家小组讨论,首先形成了包括3个一级指标、5个二级指标、21个三级指标（条目）的自评部分初步条目池,和包括2个一级指标、4个二级指标、17个三级指标（条目）的他评部分初步条目池。第1轮德尔菲咨询的专家积极系数为100%,专家权威系数Cr=0.956。自评和他评部分,专家对所有条目的重要性Kendall协调系数分别为0.424和0.449, χ²分别为133.534（P<0.001）和114.591（P<0.001）;第2轮德尔菲咨询的专家积极系数为100%,专家权威系数Cr=0.968。自评和他评部分,专家对所有条目的重要性Kendall协调系数分别为0.350和0.400, χ²分别为84.119（P<0.001）和67.546（P<0.001）。根据2轮的得分情况及专家修改意见,最终形成3个一级指标、5个二级指标、10个三级指标（条目）的自评部分条目池,和包括2个一级指标、4个二级指标、13个三级指标（条目）的他评部分条目池初始量表。结论：通过德尔菲专家咨询法构建的老年人肌少症全面评估初始量表,专家积极参与,权威度高,专家意见集中程度和协调度好。

Objective To develop the preliminary scales suitable to the comprehensive assessment scale for elderly sarcopenia in China (including self-evaluation and evaluation from others). Methods Through searching and reviewing literatures, the scales related to sarcopenia were selected and a preliminary item pool was formed. The items were screened through two rounds of Delphi consultation questionnaires completed by 16 domestic experts in related fields. Through analyzing the expert positive coefficient, expert authority level, coordination coefficient of the importance of expert opinions, average value of each index score, coefficient of variation and the full score rate, the preliminary scales for evaluating sarcopenia in the elderly were developed. Results After literature collection and expert discussion, the initial item pools of self-assessment (3 first-level items, 5 second-level items, 21 third-level items) and assessment from others (2 first-level items, 4 second-level items and 17 third-level items) were developed. The expert positive coefficient in the first round of Delphi consultation was 100%, and the coefficient of expert authority was Cr=0.956. In the self-evaluation and evaluation from others, the Kendall coordination coefficients of the importance of experts to all items were 0.424 and 0.449, and χ² were 133.534 (P<0.001) and 114.591 (P<0.001), respectively. The positive coefficient of expert in second round of Delphi consultation was 100%, and the authority coefficient of expert was Cr=0.968. In self-evaluation and evaluation from others, the Kendall coordination coefficients of the importance of experts to all items were 0.350 and 0.400, and χ² are 84.119 (P<0.001) and 67.546 (P<0.001), respectively. According to two rounds scores of Delphi consultation and the expert opinions of modification, the item pools of self-assessment (3 first-level items, 5 second-level items and 10 third-level items) and assessment from others(2 first-level items, 4 second-level items and 13 three-level items) were finally formed. Conclusions The preliminary scales for comprehensive assessment of elderly sarcopenia developed through Delphi expert consultation method involved active participation of experts, and presented high level of expert authority, and well concentrated and coordinated opinions from experts.
