Validation of the Nine-Item Avoidant/Restrictive Food Intake Disorder Screen Among Transgender and Nonbinary Youth and Young Adults.

Purpose: The purpose of the study was to provide initial evidence for the internal consistency and convergent validity of the nine-item avoidant/restrictive food intake disorder screen (NIAS) in a sample of transgender and nonbinary (TGNB) youth and young adults.

Methods: Returning patients at a Midwestern gender clinic (=164) ages 12-23 completed the NIAS, sick, control, one stone, fat, food (SCOFF), patient health questionnaire 9 (PHQ-9), and generalized anxiety disorder 7 (GAD-7) during their clinic visit. Age, sex assigned at birth, gender identity, weight, and height were also collected.

The purpose of this study was to describe the prevalence of and relationships among disordered eating, food insecurity, and weight status among transgender and gender nonbinary youth and young adults. This cross-sectional study involved a screening protocol to assess disordered eating and food insecurity risk from September to December of 2019 at a gender clinic using five validated measures: (1) previous eating disorder diagnosis (yes/no); (2) Sick, Control, One Stone, Fat, Food Questionnaire (SCOFF); (3) Adolescent Binge Eating Disorder Questionnaire (ADO-BED); (4) Nine-Item Avoidant/Restrictive Food Intake Disorder Screen (NIAS); and (5) Hunger Vital Sign.
