The reliability and the validity of the Motility and Functional Capacity Evaluation

Purpose. Reliability and validity of the English version of the Motility and Functional Capacity Evaluation (MFCE) were examined.; Methods. The MFCE was used to assess 19 functional activities, in three Categories (Manual Materials Handling, Endurance, and Balance) to obtain Category scores, as well as a Security score. A Total Functional score (total of Category and Security scores) and a Global Rating score (evaluator's classification of the subject's predicted work level) were determined from the MFCE. Work duties were determined one month post MFCE using a Current Work Status Questionnaire, which was completed by the subject and the employer. Three evaluators scored ten subjects to determine inter-rater reliability of Category, Total Functional and Global Rating scores. Construct validity was assessed by determining the level of agreement between the measures. Predictive validity was determined by comparing MFCE Total Functional and Global Rating scores to actual work status at one month post evaluation, as reported by subject and employer.
