Screening for feeding disorders. Creating critical values using the behavioural pediatrics feeding assessment scale.

The aim of the current study was to discriminate between clinical and non-clinical samples on the Behavioural Pediatrics Feeding Assessment Scale (BPFAS). The objective was to present a cut-off value, that was derived statistically, which could be used to screen for feeding disorders. A sample of five hundred and seventy-three families with a target child ranging in age from 20 to 85 months took part in the current study. Sixty-four children had a known diagnosis of a feeding disorder and were embedded into a typically developing sample of families that had not sought professional intervention. All families completed the BPFAS in order to provide a known database to measure discriminative statistics. The Receiver Operating Characteristic (ROC) analysis indicated that the cut off value for the BPFAS was a Child Frequency score of 61 and a Child Problem score of six. This offered an 87% accuracy rate at these values. The current study offered definitive evidence that the BPFAS was accurate (both sensitive and specific) to determine differences between clinical and non-clinical samples in the United Kingdom. It is therefore advocated that BPFAS should be adopted in future studies exploring the impact of feeding disorders and problems in both clinical and research settings
