Because of a shortage of valid instruments to measure the QOL of people with profound multiple disabilities (PMD), the QOL-PMD was developed. In the present study, possibilities for item reduction as well as the psychometric properties of the questionnaire were examined. One hundred and forty-seven informants of people with PMD participated in the study. Fifty items were removed from the questionnaire on the basis of preset criteria. Internal consistency was good for the total questionnaire as well as for the subscales. Evidence of the construct validity of the questionnaire was found. Correspondence between the groups of informants was moderate. The results of this preliminary analysis of the psychometric properties of the QOL-PMD are encouraging, but further validation of the measure is warranted. (Contains 6 tables.)
