The purpose of this project is to develop and evaluate the first mobile platform decision support tool for behavioral feeding intervention to address chronic feeding problems in pediatric populations that is manual-based and technology-supported. Twenty children ages 13 to 72 months (12 boys and 8 girls) received treatment for 5 consecutive days in a day treatment program (n=10) or waitlist (n=10). Primary outcome measures were bite acceptance, disruptions, and grams consumed during meals. The intervention group showed significantly greater improvements (P<0.05) on all primary outcome measures (d=1.03–2.11) compared with waitlist.
