We examined whether the Swedish adaptation of the Philadelphia Geriatric Center Multilevel Assessment Instrument (PGCMAI) developed by Lawton meets criteria for reliability and validity in an elderly Swedish population with locomotor disability. Data were collected, using the mid‐length version of the instrument, from 199 elderly people with locomotor disability in two Swedish counties. Reliability was determined by Cronbach's alpha and construct validity was tested by means of exploratory factor analysis. Comparison was made with the Standardized Practical Equipment (SPE) test. Factor analysis identified eight factors, which were comparable to the original eight domains. There was a logical correlation between the PGCMAI and the SPE test. Further psychometric testing is recommended on other groups of elderly people.
