摘　　要：目的编制2型糖尿病患者及家属饮食知信行调查问卷并检验其信效度,为医护人员对该群体的饮食管理提供参考。方法以知信行(知识-态度-行为)理论为框架,通过文献回顾结合专家咨询形成初始问卷;采用便利抽样法选取2023年6月至12月在中山大学附属第三医院内分泌科住院的236例2型糖尿病患者及其家属进行调查,对问卷进行项目分析及信效度检验。结果成功编制2型糖尿病患者及家属饮食知信行调查问卷。问卷包括知识、态度、行为3个维度,共39个条目,条目分析和问卷内容效度均达到标准。问卷总的Cronbach’sα系数为0.926(患者版)、0.946(家属版),知识、态度、行为3个维度的Cronbach’sα系数分别为0.944、0.884、0.825(患者版),0.941、0.928、0.932(家属版)。探索性因子分析提取3个公因子,累计方差贡献率为44.5%(患者版)、53.4%(家属版)。验证性因子分析结果显示,χ^(2)与自由度比为2.36(患者版)、2.58(家属版),比较拟合指数为0.84(患者版)、0.81(家属版),Tucker Lewis指数为0.83(患者版)、0.80(家属版),近似残差均方根为0.07(患者版)、0.08(家属版)。内容效度分析显示,条目水平内容效度指数为0.938~1.000,平均量表水平内容效度指数为0.977(患者版)、0.968(家属版)。结论2型糖尿病患者及家属饮食知信行调查问卷具有良好的信度和效度,或可成为医护人员开展糖尿病患者饮食管理评估的有效测评工具。Objective To develop two versions of dietary KAP(knowledge,attitude and practice)questionnaires among patients with type 2 diabetes mellitus(T2DM)and their family members,and to assess the reliability and validity,aiming to provide reference for medical staff regarding dietary education and management.Methods Based on KAP theory,the initial edition was compiled by literature reviews,semi-structured interviews,and two rounds of expert consultation.A total of 236 patients with T2DM admitted to Department of Endocrinology of the Third Affiliated Hospital of Sun Yat-sen University from June to December 2023 and their family members were selected by convenience sampling method,and the questionnaire was analyzed and tested for reliability and validity.Results Two versions of questionnaires on dietary KAP among patients with T2DM and their family members were developed.The questionnaire included three dimensions:knowledge,attitude and practice,with a total of 39 items.The item analysis and the validity of the questionnaire content reached the standard.Total Cronbach’s alpha for the questionnaire was 0.926(patient version)and 0.946(family version).The Cronbach’s alpha for the three dimensions of knowledge,attitude and behavior were 0.944,0.884,0.825(patient version)and 0.941,0.928,0.932(family version).Three common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rates were 44.5%(patient version)and 53.4%(family member version).The confirmatory factor analysis showed that the Chi-square degree of freedom ratio was calculated as 2.36(patient version)and 2.58(family member version),the comparative fit index was 0.84(patient version)and 0.81(family member version),the Tucker Lewis index was 0.83(patient version)and 0.80(family member version),and the approximate root mean square error was 0.07(patient version)and 0.08(family member version),respectively.Content validity analysis showed that the item-level content validity index was 0.938-1.000,and the average scale-level con
