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 (n=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. Confirmatory factor analysis was used to establish the hypothesized three-factor structure of the NIAS in this sample. Relationships between the NIAS subscales and anthropometric data, SCOFF, PHQ-9, GAD-7, and sex assigned at birth were explored for convergent and divergent validity, and proposed screening cutoff scores were used to identify the prevalence of likely avoidant/restrictive food intake disorder (ARFID) in this population.
Results
The three-factor structure of the NIAS was an excellent fit to the current data. Approximately one in five (22%) of the participants screened positive for ARFID. Approximately one in four participants scored above the picky eating (27.4%) or appetite (23.9%) cutoffs. Assigned female at birth participants scored significantly higher on the NIAS-Total, Appetite, and Fear subscales than those assigned male at birth. NIAS-Total was significantly related to all convergent validity variables other than age, with a moderate-strong correlation with other symptom screeners (SCOFF, PHQ-9, GAD-7), and a small negative correlation with body mass index percentile.
Conclusions
Evidence supports the NIAS as a valid measure to screen for ARFID among TGNB youth and young adults.
