Differences between questionnaire- and interview-based measures of activities of daily living (ADL) ability and their association with observed ADL ability in women with rheumatoid arthritis, knee osteoarthritis, and fibromyalgia

Abstract

Measures of self-reported ADL ability based on either questionnaire or interview have limited relationship to each other or to observed performance of ADL tasks.

Self-reported quality of ADL task performance among patients with COPD exacerbations

“…Furthermore, it was preferred over other self-report instruments because it provides both descriptive data regarding the quality of performance within single ADL tasks as well as overall linear measures of self-reported quality of ADL task performance. Previous studies support the proposition that the ADL-I can be used to generate valid and reliable linear measures of selfreported quality of ADL task performance in patients with rheumatic diseases (17,20).…”

“…Based on Rasch measurement methods, these ordinal scores are then transformed into an overall linear (interval scale) measure of self-reported quality of ADL task performance, adjusted for the difficulty of the ADL tasks (16). More detailed information about the procedures related to generating ADL-I ability measures can be found elsewhere (17,20).…”

Occupational therapy evaluation: use of self-report and/or observation?

“…The ordinal scores are then, based on the Rasch rating scale model, transformed into an overall linear (interval scale) measure of self-reported quality of ADL task performance, adjusted for the difficulty of the ADL tasks (5). Detailed information regarding the procedures related to generating ADL-I ability measures can be found elsewhere (5,7).…”

“…The psychometric properties of the ADL-I including internal scale, content, discriminative and concurrent validity, as well as precision and reproducibility have been examined in a previous study applying Rasch measurement methods (5,7). Studies support that the ADL-I can be used to generate valid and reliable linear measures of self-reported quality of ADL task performance in persons with long-term chronic diseases, including rheumatic diseases (5,7) and chronic obstructive pulmonary disease (COPD) (13).…”

“…In a previous study, Waehrens et al examined the relationship between measures based on self-report and observation, using the ADL-I and the AMPS, in a rheumatologic population (5,7). They reported a limited relationship between self-reported and observed quality of ADL task performance, stressing the need to apply both methods in that population.…”
