Development and validation of the lupus impact tracker: A patient-completed tool for clinical practice to assess and monitor the impact of systemic lupus erythematosus

Academic Article

Abstract

  • Methods. Items for the LIT were selected from the LupusPRO, a validated patient-reported outcomes measure, using 3 approaches: confirmatory factor analysis (CFA), stepwise regression, and patient focus groups. CFA was conducted to find items from the LupusPRO that fit a unidimensional structure to allow scoring as a single index. Stepwise regression methods identified items with the strongest relationship (convergent validity) with disease activity measures and patient health rating. Focus groups (n = 26 patients) identified the most important items describing SLE impact. Selected items were evaluated for reliability and validity.
