Factor Structure and Psychometric Properties of the Neonatal Eating Assessment Tool-Breastfeeding.

The purpose of this study was to identify the factor structure of the Neonatal Eating Assessment Tool-Breastfeeding (NeoEAT-Breastfeeding) and to assess its psychometric properties, including internal consistency reliability, test-retest reliability, and construct validity as measured by concurrent and known-groups validity. Exploratory factor analysis conducted on responses from 402 parents of breastfeeding infants younger than 7 months old showed a 62-item measure with seven subscales and acceptable internal consistency reliability (Cronbach's α = .92). Test-retest reliability was also acceptable (r = .91). The NeoEAT-Breastfeeding has evidence of concurrent validity with the Infant Gastroesophageal Reflux Questionnaire (r = .69) and Infant Gastrointestinal Symptoms Questionnaire (r = .62). The NeoEAT-Breastfeeding total score and all subscale scores were higher in infants with feeding problems than in typically feeding infants (p < .001, known-groups validity). The NeoEAT-Breastfeeding is a parent-report assessment of breastfeeding in infants from birth to 7 months old with good initial evidence of reliability and validity.
