Study population: The sample of this study consists of 100 participants with T1D who were being followed at the Istanbul University, Istanbul Faculty of Medicine, Endocrine and Diabetes Outpatient Clinic.

Brief summary: A growing body of research has revealed the good psychometric properties and three-component factor structure of DEPS-R in children and adolescents with type 1 diabetes (T1D) but research with adults has limited and has differing results. The Diabetes Eating Problem Survey-Revised (DEPS-R) developed by Markowitz et al is a diabetes-specific self-report instrument to screen eating disorders for individuals with T1D. DEPS-R is a 16-item diabetes-specific self-report questionnaire to test for diabetes-specific eating disorders. Answers are scored on a six-point Likert scale, with higher scores indicating more DEB and a total score of ≥20 indicating a high risk for eating disorders (range 0-80). The original DEPS-R has been shown to have a good internal consistency (Cronbach's alpha=0.86) and construct validity in a sample of the pediatric population with T1D. This study aimed to evaluate the validity and reliability of the Turkish version of the DEPS-R questionnaire for adults with T1D, investigate its psychometric properties and factor structure, and examine its relationship with the EDE-Q questionnaire.

Detailed description: In this cross-sectional study, participants answered a DEPS-R and EDE-Q questionnaire during a regularly scheduled medical visit after obtaining written informed consent. All participants had established that patients with T1D were treated with multiple daily insulin or insulin pump therapy. Height was measured using a stadiometer to the nearest 0.1 cm in all participants. Weight was measured unclothed to the nearest 0.1 kg using a calibrated balance scale. Body Mass Index (BMI) was calculated by using the weight (kg)/height (m²) equation. Clinical data including HbA1c, T1D onset, birth date, and treatment model etc. was conducted as part of a standard clinical assessment. HbA1c was measured with ion-exchange high-performance liquid chromatography (Bio-rad Variant ll Turbo, Japan).

Eligibility criteria: Inclusion Criteria:

* Duration of T1D ≥1 year
* A regular follow-up for at least 1 year (4 visits/year)
* No major medical problems related to nutrition
