OBJECTIVES: To determine whether the International Classification of Functioning,
Disability and Health (ICF) categories relevant to spinal cord injury (SCI) can
be integrated in clinical measures and to obtain insights to guide their future
operationalization. Specific aims are to find out whether the ICF categories
relevant to SCI fit a Rasch model taking into consideration the dimensionality
found in previous investigations, local item dependencies, or differential item
functioning. DESIGN: All second-level ICF categories collected in the Development
of ICF Core Sets for SCI project in specialized centers within 15 countries from
2006 through 2008. SETTING: Secondary data analysis. PARTICIPANTS: Adults
(N=1048) with SCI from the early postacute and long-term living context.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Two unidimensional Rasch
analyses: one for the ICF categories from body functions and body structures
components and another for the ICF categories from the activities and
participation component. RESULTS: Results support good reliability and targeting
of the ICF categories in both dimensions. In each dimension, few ICF categories
were subject to misfit. Local item dependency was observed between ICF categories
of the same chapters. Group effects for age and sex were observed only to a small
extent. CONCLUSIONS: The validity of ICF categories to develop measures of
functioning in SCI for clinical practice and research is to some extent
supported. Model adjustments were suggested to further improve their
operationalization and psychometrics.
