Evaluating the Validity and Consistency of the SAFER Tool

Abstract

The Safety Assessment of Function and the Environment for Rehabilitation (SAFER Tool) was designed to evaluate seniors' abilities to manage safely within their home environments. This study evaluated the content validity, internal consistency and construct validity of the Tool. Content validity was established through the use of a review panel of seniors and clinical experts, and was supported by item analyses. Internal consistency was calculated and found to be high. Construct validity was evaluated by testing hypotheses about the SAFER Tool, which were not supported. These results provide support for the content validity and internal consistency of the instrument. Further psychometric testing of the SAFER Tool is needed.
