PMID 29097981WHAT IT FOUND
The Korean Utrecht participation scale was most stable for stroke survivors' satisfaction with daily life.
Its activity frequency and participation restriction scores were less steady over two weeks, so use them with caution.
Key findings
01In the analysed stroke group, the Korean Utrecht scale's internal consistency values were 0.69 for frequency, 0.66 for restriction, and 0.67 for satisfaction.
02The satisfaction scale showed good stability (ICC 0.71), while frequency (0.63) and restriction (0.45) showed poor stability.
03The Korean Utrecht scales correlated positively with SF-12 and negatively with the London Handicap Scale, with coefficients from 0.27 to 0.62.

What it does not show
The study included only stroke survivors, so it does not show how the Korean Utrecht scale performs in people with other disabilities. Some participants were inpatients, and hospitalization may have made work, leisure, and relationship items not applicable. The test-retest analysis used only 13 participants, which is very small. The study did not conduct factor analysis because the sample size was inadequate. The study assessed only construct validity, not all forms of validity. Only 67 of 100 returned questionnaires were analysed. The internal consistency values were 0.69, 0.66, and 0.67, while the paper stated Cronbach's alpha should be at least 0.70.
The easy way to misread this
Do not conclude that the Korean Utrecht scale is equally reliable for every participation domain. The frequency and restriction scales showed poor two-week stability, while only the satisfaction scale showed good stability.
