The Sick, Control, One Stone, Fat, Food (SCOFF) is a Valid Eating Disorder Questionnaire to Use With Transgender Youth

Abstract

Transgender youth experience elevated rates of eating disorders, yet few screening measures have been validated with transgender patients. The purpose of this study was to provide initial evidence for the internal consistency and convergent validity of the Sick, Control, One Stone, Fat, Food (SCOFF) in a sample of transgender youth. Two hundred eight participants completed the SCOFF as part of a routine screening protocol. Exploratory factor analysis and confirmatory factor analysis were used to establish the factor structure of the SCOFF in this sample. Relationships between the SCOFF, Adolescent Binge Eating Disorder (ADO-BED), Nine-Item Avoidant/Restrictive Intake Disorder (NIAS), Patient Health Questionnaire 9 (PHQ-9), Generalized Anxiety Disorder 7 (GAD-7), and demographic characteristics were explored. The SCOFF was significantly related to all convergent validity variables, with moderate correlations with other eating disorder scales (ADO-BED and NIAS). The SCOFF is a valid measure to screen for eating disorders among transgender youth and young adults.
