COSMIN Ratings for Disease-specific Patient-reported Outcome Measures^a,b

Measure	Internal Consistency	Reliability	Measurement Error	Content Validity	Structural Validity	Hypothesis Testing	Cross-cultural Validity	Criterion Validity	Responsiveness
HAGOS⁶	E	F	F	E	E	E	NT	NT	G
iHOT-33⁷	P	F	NT	E	P	F	NT	NT	F
NAHS⁸	P	P	NT	P	NT	F	NT	NT	NT

COSMIN = COnsensus-based Standards for the selection of health Measurement INstrument, HAGOS = Copenhagen Hip and Groin Outcome Score, iHOT-33 = 3 3-item International Hip Outcome Tool, NAHS = Nonarthritic Hip Score

Each article was assessed by two independent reviewers (M.H.H., C.M.M.). Disagreements were discussed and consensus determined. Where consensus was not reached, a third reviewer (E.M.R.) was consulted.

Scoring: E = excellent, G = good, F = fair, P = poor, NT = measurement property was not assessed.
