This article describes the development of a new functional measure — the Monitored Functional Task Evaluation (MFTE) — a symptom-limited evaluation that is used to measure the functional performance of an individual with chronic obstructive pulmonary disease (COPD), and to document a client's physiological changes through repeated testing. Stage I of the study included developing the content validity of the instrument. Stage II consisted of establishing the performance profile, test-retest and inter-rater reliability using a convenience sample of 27 inpatients and outpatients who had COPD. In stage III, the criterion-related and discriminative validity of the instrument was verified in a retrospective sample of 124 inpatients and day patients who had COPD. Results indicated that there was high intra- and inter-rater reliability for the total score of MFTE. Significant correlation of the MFTE was found with parameters such as Moser's Activities of Daily Living (ADL) class, COPD disability class, 6-minute walking distance, work capacity in terms the ratio of the metabolic rate associated with a given activity to the resting metabolic rate, and the fatigue dimension of the Chronic Respiratory Disease Questionnaire. In addition, prediction of group membership to Moser's ADL class revealed that 52.4 % of the original grouped cases could be correctly classified by the MFTE alone. In conclusion, the MFTE is a useful measure to evaluate functional performance as well as document physiological changes in patients with moderate-to-severe COPD from both conceptual and empirical perspectives.
