Note. ARFID – avoidant/restrictive food intake disorder; AN – anorexia nervosa; M – mean; SD – standard deviation; N/A – not applicable.
There was a statistically significant difference in age between ARFID and AN (p < .001, Cohen’s d = .94).
We used the PARDI to determine presence/absence of each ARFID profile for n = 42 individuals in study R01MH108595. The n = 9 individuals with ARFID who we recruited as part of study R01MH103402 are not represented in this table because we did not administer the PARDI to participants in this study. Combined percentages exceed 100% because, consistent with Thomas and colleagues’ (2017) three-dimensional model of ARFID, participants could present with more than one profile.
