Abstract
The purpose of this study was to develop an easy-to-use and psychometrically sound outcome instrument that is task-oriented and patient-centred. One hundred fifteen patients with a variety of hand impairments completed a rating scale of perceived manual ability (i.e., the Manual Ability Measure). The first 70 patients also completed two other questionnaires about physical health and psychological well-being. Rasch Analyses were conducted to transform the ordinal ratings into linear measures; Rasch statistics were used to evaluate its measurement properties at both scale and item levels. Eighty-three original items were reduced to 16 common tasks; Rasch reliabilities were good; the easy-to-difficult item hierarchy makes sense clinically. Moderate correlations were found between manual ability, physical function and general sense of well-being. The results of this preliminary study suggest that the MAM is a promising outcome measure that has adequate psychometric properties and can be used to complement other objective clinical measurements.
