Note. ARFID=avoidant/restrictive food intake disorder; NIAS=Nine Item ARFID Screen; other-ED=eating disorder associated with shape/weight concerns; NP=nonclinical participant; M=mean; SD=standard deviation. For post-hoc tests, we used Bonferroni correction to adjust for multiple comparisons.
These items do not add to 100%, since participants could be associated with multiple categories
Represents R2 value because sex was a binary variable in the current sample and differences were computed using logistic regression.
Indicates this sample’s score was significantly higher than the sample(s) who scored lower on this measure (p<.05) (e.g., the ARFID group scored significantly higher on the NIAS than the other-ED group, and the other-ED group scored significantly higher on the NIAS than the NP group).
