Modified COSMIN Checklist for Scoring of Outcome Measures

Score	Meaning	Description
5	Highly Recommend	• Excellent reliability (test-retest, inter-rater, intrarater, and/or responsiveness) • Excellent validity (content, construct, and criterion validity) • Easy to interpret scores (can be used by individuals of differing expertise or no training required) • Evidence of cross-cultural validity • Excellent clinical utility across a majority of the following: short, does not require a lot of supplies, applicable for many intellectual/physical ability levels, can readminister within short period of time, wide age range of assessment allows for follow-up within patient tracking over time) • Data to support psychometric utility is strong (validated in a pediatric stroke population or relevant/related populations) • Sensitive to change over time (minimal clinically important difference) has been established, low likelihood of ceiling or floor effects)
4	Recommend	• Good reliability • Good validity • Easy to interpret scores • Minimal evidence of cross-cultural validity • Strong clinical utility (meets half of the criteria) • Data to support psychometric utility is strong • Sensitive to change over time
3	Recommend, nonpreferred	• Minimal evidence of reliability • Minimal evidence of validity • Some barriers to score interpretation • Minimal or reported evidence of cross-cultural validity • Meets some clinical utility criteria • Data to support psychometric utility is strong but has not been validated in a pediatric stroke or relevant/related population or is an adult measure that has been adapted for use in pediatric populations • Sensitive to change over time—no published data
2	Unable to recommend at this time	• Limited information with regard to psychometrics but has clinical utility (might be a measure that is often used clinically but has little research available)
1	Do not recommend	Poor psychometrics and poor clinical utility or measure is rarely used so there is little to no data on the measure

Abbreviation:

COSMIN = Consensus-based Standards for the Selection of Health Measurement Instruments

Modified COSMIN Guidelines were used for rating the individual measures. A scale of1to 5 was utilized; if majority of the criteria (>5 items) were met within a given score category, the measure would receive that score. The reliability and validity criteria both had to be satisfied to meet a given score category. Definitions of each scoring criteria were provided (refer to Supplemental Document 1).
