Abstract

Abstract Frailty is a theoretical concept used to track individual age-related declines. Persons with intellectual disabilities (ID) often present with pre-existing deficits that would be considered frailty markers in the general population. The previously developed Vienna Frailty Questionnaire for Persons with ID (VFQ-ID) was aimed at assessing frailty in this specific population. However, findings of the initial frailty study in 2007 revealed some weaknesses. This paper reports on the development of the Vienna Frailty Questionnaire for Persons with ID – Revised (VFQ-ID-R) as well as its first application and psychometric evaluation. The authors re-administered the VFQ-ID-R to participants with ID who had been assessed with the VFQ-ID in 2007. The goal was to study the factor structure and reliability of the revised test. Internal consistency of the VFQ-ID-R was found to be very good for the entire scale and was moderate for the four domains of the scale. Inter-rater reliability and retest reliability were found to be good. The revisions made to the VFQ-ID will be useful in assessing and supporting ageing individuals with ID.
