Turkish Validity and Reliability Study of Diabetes-Specific Nutrition Knowledge Questionnaire in Adolescents With Type 1 Diabetes

The aim is to analyze the validity and reliability of the Diabetes-Specific Nutrition Information Scale in Adolescents with Type 1 Diabetes for the Turkish population. In this context, the relationship between nutritional knowledge levels, glycemic control and diet quality will be investigated with the Nutrition Knowledge Scale in Adolescents with Type 1 Diabetes.

The sample of the study consists of individuals between the ages of 10-19 with Type 1 diabetes registered at Ege University Faculty of Medicine, Department of Child Health and Diseases, Pediatric Endocrine Department, in Izmir province, and their parents. In the first stage, it will be validated with the Brislin method for Turkish language validity. Later, validity and reliability analysis will be conducted. The relationship between individuals' nutritional knowledge levels and diet quality (adapted to Healthy Eating Index-2015 TÜBER-2022) and metabolic control (with last measured HbA1c) will be examined. The case report form created for this purpose, the food consumption monitoring form, SYI-2015 adapted to TÜBER 2022 and the Turkish version of the Diabetes-Specific Nutrition Information Scale in Adolescents with Type 1 Diabetes will be used.
