All participants completed the PARDI-AR-Q and EDE-Q, so correlations among SBA, LOI, FAC, and EDE-Q are based on the full data set. Because only a subsample completed FNS (n = 54) and NIAS (n = 41), FNS, PE, LA, and F correlations including those variables reflect the subset only
SBA PARDI-AR-Q sensory-based avoidance; LOI PARDI-AR-Q lack of interest in eating or food; FAC PARDI-AR-Q concern about aversive consequences; SOI PARDI-AR-Q severity of impact; FNS food neophobia scale; PE nine-item ARFID screen (NIAS) picky eating; LA NIAS low appetite; F NIAS fear; EDE-Q eating disorder examination-questionnaire global score
