Abstract: Objective To develop Adolescent Intuitive Eating Scale, and to test its reliability and validity, so as to provide a reliable tool for the evaluation of adolescent intuitive eating in China. Methods Through literature review, the initial item pool of the scale was established, and the Delphi expert consultation method was used to modify the scale. A survey of 594 adolescents in September 2020 to July 2021 was conducted to evaluate the reliability and validity of the scale. Results 1) The Adolescent Intuitive Eating Scale included 4 dimensions and 19 items. 2) In the decision value analysis, the effective item scores of high score group and low score group were compared, and the differences were statistically significant (P＜0.01). Pearson correlation analysis result indicated that the correlation coefficient between the effective item score and the total score of the scale ranged from 0.555 to 0.755 (P＜0.05). 3) The value of I-CVI ranged from 0.800 to 1.000, the S-CVI/UA and S-CVI/Ave was 0.842 and 0.968, respectively. Finally 4 common factors were extracted by exploratory factor analysis, and the cumulative contribution rate of variance was 78.555%. Confirmatory factor analysis result showed the load value of each item in the factor to which it belonged ranged from 0.699 to 0.918, and the values of indicators such as(average variance extraction,AVE), CR, RMR and SRMR were all within the reliability limit. In terms of standard correlation validity analysis, the total scores and scores of each dimension of the Adolescent Intuitive Eating Scale was positively correlated with the total score of the adult version of the Intuitive Eating Scale (r=0.272 - 0.803, P＜0.01).4) The values of Cronbach's α coefficient, half-fold reliability, and test-retest reliability of the Adolescent Intuitive Eating Scale were 0.923, 0.738 and 0.928, respectively. Conclusions The Adolescent Intuitive Eating Scale has good reliability and validity, and can be used as a tool for evaluating the adolescent intuitive eating situation in China.

摘要： 目的 编制青少年直觉进食量表并进行信效度检验,为我国青少年直觉进食评估提供可靠工具。方法 2020年9月—2021年7月采用文献回顾法建立量表初始条目池,通过Delphi专家咨询法对量表进行修改,并调查594名青少年以测评量表的信效度。 结果 1)青少年直觉进食量表包括4个维度、19个条目。2)项目分析:决断值分析中,有效条目高、低分组得分比较,差异有统计学意义(P＜0.01);Pearson积差相关性分析中,有效条目得分和量表总分的相关系数为0.555~0.755(P＜0.05)。3)效度分析:条目水平的内容效度指数(I-CVI)范围为0.800～1.000,全体一致量表水平的内容效度指数(S-CVI/UA)=0.842,平均量表水平的内容效度指数(S-CVI/Ave)=0.968;探索性因子分析共抽取4个公因子,方差累积贡献率为78.555%;验证性因子分析各条目在其所属因子中的载荷值范围0.699~0.918,平均方差萃取(AVE)、组合信度(CR)、拟合指标残差均方和平方根(RMR)、标准化残差均方和平方根(SRMR)等指标均在可靠性界值内;效标关联效度分析中,青少年直觉进食量表总分、各维度分与成人版直觉饮食量表总分、各维度分均呈正相关(r=0.272~0.803,P＜0.01)。4)信度分析:青少年直觉进食量表Cronbach's α 系数、折半信度、重测信度分别为0.923、0.738、0.928。结论 青少年直觉进食量表信效度良好,可作为我国青少年直觉进食情况的测评工具。
