Descriptive statistics, internal consistency, and test-retest reliability
| Scale/item | Missing* (%) | Does not apply (%)† | Mean‡ | SD | Cronbach’s alpha/item-total correlation(n = 18829) | Test-retest intraclass correlation(n = 139) |
|---|---|---|---|---|---|---|
| *For scale scores the number of missing values is the sum of responses to the “does not apply” category and true missing values—that is, where a scale score is not calculable. | ||||||
| †For scale scores the figure for “does not apply” is equal to the number of patients for whom a scale score was not calculable because they responded “does not apply” to half or more items within the scale. | ||||||
| ‡Items are scored 0–9 and scales are scored 0–100 where higher scores represent better experiences. | ||||||
| §Values for Cronbach’s alpha are in italics. | ||||||
