Validity and Usability of a Safe Driving Behavior Measure for Older Adults, Summary Report.

摘要

The researchers used three measures to establish FTDS's validity: face validity, content validity, and construct validity. Focus groups of OTs, CDRSs, and family members examined the FTDS and determined its face validity, meaning that, from their perspective, the test appeared to measure what it was intended to. Expert reviewers set the FTDS's content validity index at 84 percent. Rasch analysis determined construct validity.
