Construction and validation of content of one instrument to assess falls in the elderly.

Objective: To develop and validate the content of the online Questionnaire for Fall Risk Assessment in the Elderly.

Methods: The instrument was developed based on the International Classification of Functioning, Disability and Health (ICF) of the World Health Organization. Initially, the set of items was submitted to evaluation of judges (healthcare professionals with experience in elderly health), who could suggest inclusion or exclusion of questions from the instrument; they were also asked to rate each question according to the expected scope.
