As in Ahearn et al. (2001), we categorized children as high, moderate, or low on acceptance based on the number of bites
accepted across food groups. Each meal consisted of 96 presentations, 24 of which were pureed texture and 66 of which were
table texture. We defined low acceptance as acceptance of fewer than 1/3 of the table-texture presentations, moderate
acceptance as acceptance of 1/3 to 2/3 of table-texture presentations, and high acceptance as acceptance of 2/3 to 100% of
presentations. We categorized children as texture selective if they accepted 75% or more of the presentations at the pureed
texture.
We summarized the Food Frequency Questionnaire data by summing the total number of foods consumed across food
groups and total number of foods consumed within each food group for each child with autism and for each family member.
We tallied the number of categories in which an individual never consumed any foods for each individual.
We used correlational analysis to examine the relation between the Brief Autism Mealtime Behavior Inventory and Food
Frequency Questionnaire and behaviors observed during the examiner-led observation. We used Pearson product
correlations to examine the relation between ASD symptomatology and feeding problems.
