Reliability and Validity of a Nutrition and Food-Label Knowledge Test for Women with Type 2 Diabetes Mellitus

Introduction: Type 2 diabetes mellitus is a non-communicating disease with an increasing trend in Malaysia. One of the most important aspects in the selfmanagement of diabetes mellitus is the assessment of knowledge among diabetes patients. This study aimed to translate and validate the Malay version of Modified Diabetes Knowledge Test (DKT) questionnaire. Methods: A standard back-to-back translation procedure was used to translate the simplified version of the DKT questionnaire from the original version. A total of 120 outpatients with type 2 diabetes mellitus from the government primary care clinic were selected to answer the questionnaire which consists of socio-demographic and diabetes characteristics questions as well as the 20-item DKT questions. Reliability and validity were tested with Cronbach’s alpha and Exploratory Factor Analysis. Results: The Cronbach’s alpha for the translated questionnaire was acceptable (α=0.573) with the Cronbach’s alpha excluding each item ranged from 0.517 to 0.602. Factor analysis with Varimax rotation identified 6 domains for the 18 items, with 2 to 6 items in each domain. Conclusion: This version of simplified DKT is proven to be valid and reliable, and can be used with caution as a brief assessment of knowledge among diabetic patients specifically tailored for Malaysian population.

The aim of this study was to prepare a Japanese version of the “Satisfaction of Treatment among Caregivers of Dependent Type 2 Diabetic Patients” (STCD2-J) questionnaire, which is used to assess the satisfaction of family caregivers with respect to the treatment for elderly patients with type 2 diabetes mellitus who require support. In addition, the reliability and validity of the STCD2-J questionnaire were analyzed. A Japanese version of the original STCD2 questionnaire was prepared, revised, and back-translated; the back-translated version was sent to the authors of the original version for confirmation. Family caregivers of patients with type 2 diabetes mellitus aged ≥65 years who regularly underwent medical examinations at the diabetes mellitus outpatient clinic of Ise Red Cross Hospital were included. Cronbach’s α coefficient was calculated to assess internal consistency. Exploratory factor analyses were performed to assess construct validity, and Pearson’s correlation coefficients between STCD2-J score and HbA1c as well as the degree of satisfaction with patients’ blood glucose levels, depression, and negative self-assessment of nursing care were calculated to assess criterion-related validity. This study included 208 individuals (55 males and 153 females). Cronbach’s α coefficient was 0.88. Factor analyses showed a single-factor structure both with and without rotation. The STCD2-J scores were significantly inversely correlated with HbA1c (r=−0.27, P<0.001). Significant correlations were observed between the STCD2-J scores and degree of satisfaction with patients’ blood glucose levels (r=0.43, P<0.001), depression (r=−0.20, P=0.003), and negative self-assessment of nursing care (r=−0.19, P=0.004). The reliability and validity of the STCD2-J questionnaire were confirmed. The STCD2-J questionnaire can be used in Japan as a tool to assess the satisfaction of family caregivers with the treatment of elderly patients with type 2 diabetes mellitus requiring support.
