To determine the dimensionality, reliability, model fit, adequacy of the qualifier levels, response patterns across different factors, and targeting of the International Classification of Functioning, Disability and Health (ICF
) osteoarthritis core set categories in people with osteoarthritis undergoing hip and knee arthroplasty.
The osteoarthritis core set was rated in 316 persons with osteoarthritis who were either in the pre-operative or within one year post-operative stage. Rasch analyses were performed using the RUMM 2030 program.
Twelve of the 13 body functions categories and 13 of the 19 activity and participation categories had good model fit. The qualifiers displayed disordered thresholds necessitating rescoring. There was uneven spread of ICF
categories across the full range of the patients' scores indicating off--targeting. Subtest analysis of the reduced ICF
categories of body functions and activity and participation showed that the two components could be integrated to form one measure.
The results suggest that it is possible to measure functioning using a unidimensional construct based on ICF
osteoarthritis core set categories of body functions and activity and participation in this population. However, omission of some categories and reduction in qualifier levels are necessary.
Further studies are needed to determine whether better targeting is achieved, particularly during the pre-operative and during the sub-acute care period.
