^†Results are shown for each structural equation and mediation model with picky eating (left panel) and ARFID diagnosis (right panel) as two separate outcomes. N=1644. Abbreviations: ARFID: Avoidant/Restrictive Food Intake Disorder; S.E. = standard error; IE = indirect effect; DE = direct effect (including mediator in the model); DV = dependent variable; → = “predicts;” ⇔ =“correlates with;” df = degrees of freedom; CFI = Comparative Fit Index; TLI = Tucker-Lewis Index; RMSEA = root mean square error of approximation.
