title: Methodological considerations in functional assessment.
abstract: A large number of functional status assessments are currently available. Choosing among them can be difficult. Instruments vary widely in their content, detail of questions, type of scale and length of administration. In addition, some have undergone more extensive testing for reliability and validity than others. We have developed a checklist to compare and evaluate the usefulness of such instruments.
