Abstract
PurposeTo evaluate the psychometric properties of the Chinese version of the Hypoglycemia Fear SurveyII (HFS-II) in patients with type 2 diabetes mellitus from Tianjin City.MethodsThe original HFS-II was translated and adapted to Chinese.350 inpatients from five hospitals of Tianjin completed the Chinese HFS-II. We examined the validity (content and construct validity) and reliability (internal consistency and test-retest reliability) of the scale. Content validity was evaluated by the content validity index (CVI) and the average agreement CVI(S-CVI/Ave). The construct validity was assessed by exploratory factor analysis. Reliability was measured by intraclass correlation coefficient (ICC) and Cronbach’s alpha.ResultsThe mean age of the 350 patients was 55.5±9.3years. The CVI was 0.71~1.0 and S-CVI/Ave was 0.92 respectively. By exploratory factor analysis, four factors were extracted which accounted for 52.15% of the total variance in the 23-item scale. The Chinese HFS-II displayed good internal consistency (Cronbach’s alpha = 0.90) and test–retest reliability (ICC = 0.96).ConclusionsThe Chinese version of HFSII had excellent psychometric properties and it could provide a useful tool for clinicians and nursing staff to assess the fear of hypoglycemia.

Hypoglycemia unawareness is not preceded by warning signs mentioned above, which means a patient with low blood glucose concentration may not take any remedial action, becomes severely hypoglycemic
Summary
In China, the prevalence of diabetes has increased dramatically over the past 30 years[1]. The Hypoglycemia Fear Survey (HFS) was developed in 1987[9], which was revised in 2011 as the version of HFS-II It consists of HFS-II-Worry Scale (HFSII-WS) and HFS-II-Behavior Scale (HFSII-BS) with a total of 33 items, which was widely used to measure worries and behaviors of FoH. Since it was first published, HFS-I, in its original form and subsequent revisions, has been used in 60 published studies and numerous clinical trials and translated into 50 countries, though not in China.
