The translation process followed standard guidelines for adaptation of an instrument: forward translation, back translation, synthesis, evaluation by an expert panel and pretest. The expert panel included three English specialists as linguistic experts and six content experts in multidisciplinary areas relevant to the study. The pretest was conducted on a sample of 31 type 2 diabetics in the Endocrinology outpatient clinic at Trung Vuong hospital. Content validity was determined based on experts’ concurrence using content validity index for items (I-CVI). Face validity is assessed by participants in pretest. Internal consistency was measured using Cronbach’s alpha. |
