Introduction
Disordered eating behaviors are more prevalent among adolescents with type 1 diabetes (T1D) and are associated with poorer metabolic outcomes. Current guidelines from the American Diabetes Association and International Society for Pediatric and Adolescent Diabetes recommend routine screening for eating disorder risk in this population. Although the Diabetes Eating Problem Survey-Revised (DEPS-R) is widely used, its length may limit its use in routine clinical practice. The M-SCOFF questionnaire, as a brief screening tool, may provide a more practical alternative.
Objectives
This study aimed to evaluate the validity and screening performance of the Turkish version of the M-SCOFF in adolescents with T1D
Methods
In this methodological study, 150 adolescents with T1D completed the Turkish version of the M-SCOFF and the DEPS-R. Convergent validity was assessed through correlations with DEPS-R scores. Screening performance was evaluated using receiver operating characteristic (ROC) analysis. Test–retest reliability was examined in a subsample.
Results
The M-SCOFF showed a strong positive correlation with DEPS-R scores (r = 0.683, p < 0.001). Agreement in risk classification between the two tools was moderate (κ = 0.544). ROC analysis indicated good discriminatory ability (AUC = 0.835). At a cutoff score of ≥2, sensitivity was 71.1% and specificity was 85.7%. Test–retest reliability was high, whereas internal consistency was low.
Conclusions
The Turkish version of the M-SCOFF appears to be a brief and practical tool for identifying eating disorder risk in adolescents with T1D. Although internal consistency was low—likely reflecting the dichotomous and screening-oriented nature of the instrument—the questionnaire demonstrated acceptable validity and screening performance. These findings support its use as a rapid screening tool in busy clinical settings.
