Abstract

Objective: This study aimed at examining the psychometric properties of Persian version of Multidimensional Health Locus of Control scale, form C (MHLC-C) among Iranian type 2 diabetes.

Method: This cross sectional study was conducted on 557 type 2 diabetes in eastern city of Iran in 2022. Participants were selected by proportional stratified sampling. The validity of MHLC-C was tested by face validity, content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA).Reliability of MHLC-C was assessed by McDonald omega coefficient, Cronbach's alpha coefficient, and Intraclass Correlation Coefficient.

Results: Based on the results of EFA, 4 factors with eigenvalues greater than 1 were extracted, which explained 61.66% of the variance. In EFA, a question was removed. In CFA, the factor loading of all questions was more than 0.4 and the indexes of the goodness-of-fit were acceptable (for example: X²/df = 4.457, RMSEA: 0.079, CFI = 0.904, and PGFI = 0.663). McDonald omega coefficient and Cronbach's alpha coefficient of MHLC-C were 0.869 and 0.866. The Intraclass Correlation Coefficient of MHLC-C was 0.817. Finally, the MHLC-C with 17 questions and 4 factors of chance (6 items), internal (5 items), other powerful people (3 items), and doctors (3 items) was approved.

Conclusions: The Persian version of the MHLC-C questionnaire, with 17 questions and four factors, is a valid and reliable scale for Iranian type 2 diabetes to assess their health locus of control status.

伊朗2型糖尿病患者多维健康控制点量表C型的心理测量特性。

目的：本研究旨在检验波斯版C型多维健康源量表（MHLC-C）在伊朗2型糖尿病患者中的心理测量特性。方法：本项横断面研究于2022年在伊朗东部城市对557例2型糖尿病患者进行。参与者是通过比例分层抽样选出的。采用面孔有效性、内容有效性、探索性因素分析（EFA）和验证性因素分析法（CFA）对MHLC-C的有效性进行检验。采用McDonaldω系数、Cronbachα系数和组内相关系数对MHLC-C的可靠性进行评估。结果：在EFA结果的基础上，提取出4个特征值大于1的因素，解释了61.66%的方差。在全民教育中，删除了一个问题。在CFA中，所有问题的因子负荷都大于0.4，拟合优度指数都是可接受的（例如：X2/df = 4.457，RMSEA:0.079，CFI = 0.904和PGFI = 0.663）。MHLC-C的McDonaldω系数和Cronbachα系数分别为0.869和0.866。MHLC-C的组内相关系数为0.817。最后，MHLC-C包含17个问题和4个机会因素（6个项目）、内部因素（5个项目），其他有权势的人（3个项目）和医生（3个项），获得批准。结论：波斯版MHLC-C问卷包含17个问题和4个因素，是评估伊朗2型糖尿病健康控制点状况的有效和可靠的量表。
