Psychological Factors and Self-Care Behaviors in Spanish Youth With Type 1 Diabetes: Age- and Sex-Based Comparisons and Associations

This is a multicenter, observational, cross-sectional study of young people aged 10 to 25 with type 1 diabetes in Spain, affiliated with a diabetes association or federation. Data will be collected through an online questionnaire in which participants voluntarily and anonymously self-report their responses. The study aims to assess psychological factors (psychological distress, risk of eating disorders, and self-perceived health status), health care behaviors (treatment adherence, diet, and physical activity), and sociodemographic data, exploring differences by age and sex and examining associations between variables.
