Abstract

Objectives: The Clarke questionnaire, validated in Spanish language, assesses hypoglycemia awareness in patients with type 1 diabetes. This study aimed to analyze its psychometric properties in patients with type 2 diabetes (T2DM).

Methods: This was a questionnaire validation study. Patients with T2DM and treated with insulin, sulfonylureas or glinides were consecutively recruited from six endocrinology consultations and six primary care centers. The internal structure of the 8-item Clarke questionnaire was analyzed by exploratory (training sample) and confirmatory (testing sample) factor analysis; the internal consistency using Omega's McDonald coefficient; and goodness of fit with comparative fit index (CFI, cutoff >0.9), Goodness of Fit Index (GFI, cutoff >0.9), and root mean-square error of approximation (RMSEA, cutoff <0.09), as well as unidimensionality indicators.

Results: The 265 participants (56.8% men) had a mean age of 67.8 years. Confirmatory factor analysis for one dimension obtained poor indicators: fit test (p < 0.001); CFI = 0.748; RMSEA = 0.122 and SRMR = 0.134. Exploratory factor analysis showed 2 or 3 dimensions with poor adjustment indicators. Omega's McDonald was 0.739.

Conclusions: The Spanish version of the Clarke questionnaire was not valid or reliable for assessing hypoglycemia awareness in people with T2DM in Spanish population.

Clarke问卷对西班牙2型糖尿病患者低血糖意识的心理测量特性

目的:西班牙语验证的Clarke问卷，评估1型糖尿病患者的低血糖意识。本研究旨在分析其在2型糖尿病(T2DM)患者中的心理测量特性。方法:采用问卷验证法。T2DM患者接受胰岛素、磺脲类药物或格列尼德治疗，从6个内分泌科会诊和6个初级保健中心连续招募。采用探索性因子分析(训练样本)和验证性因子分析(检验样本)分析8项Clarke问卷的内部结构;内部一致性采用Omega’s McDonald系数;比较拟合指数(CFI，截止值>0.9)、拟合优度指数(GFI，截止值>0.9)和近似均方根误差(RMSEA，截止值)的拟合优度。结果:265名参与者(男性56.8%)平均年龄67.8岁。结论:西班牙语版Clarke问卷对于评估西班牙人群中T2DM患者的低血糖意识是不有效或不可靠的。

期刊介绍： Postgraduate Medicine is a rapid peer-reviewed medical journal published for physicians. Tracing its roots back to 1916, Postgraduate Medicine was established by Charles Mayo, MD, as a peer-to-peer method of communicating the latest research to aid physicians when making treatment decisions, and it maintains that aim to this day. In addition to its core subscriber base, Postgraduate Medicine is distributed to hundreds of US-based physicians within internal medicine and family practice.
