About this study
It is aimed to contribute to the Turkish Nutrition Sciences literature and shed light on the studies of future generations by establishing the Turkish validity and reliability of this scale, which was developed for adolescents with type 1 diabetes and their parents and was designed to evaluate general and diabetes-specific nutrition knowledge.
Hypotheses:
- H1: Diabetes-Specific Nutrition Information Scale for Adolescents with Type 1 Diabetes is a reliable tool for the Turkish population.
- H2: Diabetes-Specific Nutrition Information Scale for Adolescents with Type 1 Diabetes is a valid tool for the Turkish society.
- H3: Individuals with higher scores on the Diabetes-Specific Nutrition Information Scale in Adolescents with Type 1 Diabetes have better metabolic control.
- H4: Diet quality of individuals with higher scores on the Diabetes-Specific Nutrition Information Scale for Adolescents with Type 1 Diabetes is better.
Read the detailed description
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.
