The purpose of this study was to identify the factor structure of the Child Oral and Motor Proficiency Scale (ChOMPS) and to evaluate the psychometric properties, including internal consistency reliability, test–retest reliability, and construct validity as measured by convergent and known-groups validity. Principal component analysis with varimax rotation conducted on responses from 364 parents of children between 6 months and 7 years of age identified four subscales: complex movement patterns, basic movement patterns, oral-motor coordination, and fundamental oral-motor skills. Acceptable internal consistency reliability (Cronbach’s α = .97) and test–retest reliability (r = .98) were found. Convergent and known-groups validity were supported by significant associations between the ChOMPS and validation measures, as well as significant differences in the ChOMPS scores between children with and without feeding problems. The ChOMPS is a 63-item parent-report measure of eating, drinking, and related motor skills in children aged 6 months to 7 years with evidence of reliability and validity.
