Evaluation of the Association Between Depression and Glycemic Control in People With Type 1 Diabetes

Study Overview
=================
Brief Summary
-----------------
Single-center prospective observational pilot study The aim of the study is to evaluate the potential association between the percentage of time spent in the optimal glycemia range and the score obtained in the questionnaires used to screen for depression. The study involves only one visit for each participant. Each participant will be asked to sign the informed consent to the study and, during the visit, the following information will be acquired: parameters, history of diabetes, concomitant diseases and medications, and CGM metrics. The participant will be administered the following questionnaires for the evaluation of depression, patient-reported outcome measure (PROMs) and treatment satisfaction: Patient Health Questionnaire (PHQ-9) Center of Epidemiological Studies-Depression Scale (CES-D) Diabetes Treatment Satisfaction Questionnaire (DTSQ) Well-Being Index (WHO-5) Problem Areas In Diabetes (PAID-5) European Quality of Life, Five Dimension, Five Level (EQ5D5L)
