Neonatal Eating Assessment Tool – Mixed Breast –and Bottle-Feeding (NeoEAT – Mixed Feeding)	Assess infant behavior during feeding in infants who are feeding at both breast and bottle; Parent	All infants birth to 7 months old, including those born healthy, full-term, preterm, and with any medical conditions	68 items; Infant regulation, gastrointestinal tract function, energy & physiologic stability, sensory responsiveness, and feeding flexibility	+	NR	+	+	+
				Internal consistency- Cronbach’s α = .88 for full scale, Cronbach’s α = .77–.91 for all subscales. Test-retest – r = .91 for full scale, r = .77–.88 for all subscales.			Content validity with 9 professionals – scale level CVI = .90 for clarity and .93 for relevance. Content validated with 19 parents using cognitive interviews [39]. Construct validity – Concurrent validity with the I-GERQ-R (r = .57; p < .001) and IGSQ (r = .5; p < .001). Known-groups validity- infants with feeding problems scored significantly higher than those without for full scale (p < .001) and all subscales (p < .05).

+Indicates acceptable reliability/validity, − indicates unacceptable reliability/validity
