Structural Validity of the Functional Assessment for Control of Trunk (FACT) for Patients with Acute Stroke Using Rasch Analysis

Abstract

[Purpose] The purpose of this study was to examine the structural validity of the Functional Assessment for Control of Trunk (FACT) using Rasch analysis. [Participants and Methods] Sixty patients with acute stroke were included in this study. FACT was measured at admission and discharge, and a Rasch analysis was performed. [Results] Items 1 and 2 were excluded from the analysis. Item 9 had the highest level of difficulty, and item 10 with 3 points did not have a high level of difficulty. In addition, three items had a poor fit. [Conclusion] Rasch analysis showed that the FACT items are valid, except for the 5 items that were excluded or showed a misfit.
