Scale Name	Target Population	No. of Levels	Direction	Diet Restriction Specifications
Functional Status Scale³	Pediatrics	5	1 (normative function) to 5 (severe dysfunction)	Total oral feeding to progressive degrees of assistance, tube-feeding, or parenteral nutrition.
Swallowing Performance Status Scale⁴	General	7	1 (normative function) to 7 (severe dysfunction)	Not described
Dysphagia Outcome and Severity Scale⁵	General	7	7 (normative function) to 1 (severe impairment)	Number of consistencies tolerated or restricted
American Speech-Language Hearing Association National Outcome Measures Scale Functional Communication Measure for Swallowing⁶	General	7	7 (normative function) to 1 (severe impairment)	Number of levels below a regular diet status in either solid or liquid consistency
FOIS⁷	Stroke	7	7 (total oral diet) to 1 (exclusive tube feeding)	Number (single vs multiple) of consistencies taken orally
UK Therapy Outcome Measurement Scale^8,9	General	6	5 (least severe impairment) to 0 (most severe impairment). Half-point scaling permitted.	Oral vs nonoral nutrition and range of consistencies allowed (limited, modified, most, and full).
