Factor structures of the Swedish Version of the RFIPC: Investigating the Validity of Measurements of IBD Patients’ Worries and Concerns
Abstract
Methods: A sample consisting of 195 patients with IBD filled out the RFIPC. Confirmatory factor analysis was performed to examine fit of three hypothesized models of factor structure. Spearman’s correlation and Mann-Whitney analysis were used to follow up the results.
Results: The single-factor model displayed poor fit indices. The four-factor model marked substantive improvement, but still remains inadequate. The final four-factor model permitting correlated error terms between some items displayed the most adequate fit.
Conclusions: The factorial structure of the RFIPC, as suggested in the original version, was able to be replicated with a slight modification in the Swedish version. The separate factors identified in this structure provide more detailed information about the worries and concerns of IBD patients as these components of worries are different related to HRQOL and general health.
