The test-retest reliability of a revised version of the Readiness for Interprofessional Learning Scale (RIPLS)

The original version of the Readiness for Interprofessional Learning Scale (RIPLS) was published by Parsell and Bligh in 1999. The only aspect of reliability considered by the authors was the internal consistency. A revised version for use with undergraduate students was published in 2005 (McFadyen et al., 2005). That paper also reported internal consistency of the revised version. Subsequently a sample from one professional group (n = 65) was used to assess test-retest reliability, over a one week period, of each of the 19 items and of the sub-scale totals, using Weighted Kappa and the intra-class correlation (ICC) respectively, and these results are reported in the present paper. The test-retest reliability of the individual items using Weighted Kappa was satisfactory, with the exception of two items (Items 11 and 12). The ICC results for the sub-scale totals were all in excess of 0.60 with the exception of sub-scale two. This revised version of RIPLS would appear to have good reliability in three of its sub-scales but further research, with larger samples, is required before the fourth sub-scale can be reliably assessed.
