An instrument to measure job satisfaction of certified nurse assistants

We first presented the steps taken to develop the nursing home certified nurse assistant job satisfaction questionnaire (NH-CNA-JSQ) and, second, the psychometric properties of this instrument. Certified nurse assistants (CNAs) from 22 nursing homes in Pennsylvania were mailed the NH-CNA-JSQ. Of the 726 surveys mailed, 479 usable surveys were returned, giving a 66% response rate. The factor analyses show that the items were representative of the underlying factors, representing seven subscales. The percentage of CNAs not providing responses for each question was low (1.5%), and the floor and ceiling effects of the responses for each of the 19 questions were low (i.e., 9.4% and 5.2%, respectively). The item-scale internal consistency analyses determined that the correlation of items within indexes was higher than those of items with other indexes. Cronbach's alpha values for the domains ranged from .72 to .83 and were all higher than the usually recommended levels. Criterion validity was high (.77) as was the index of content validity (p > .05). We believe that we have produced a short psychometrically sound job satisfaction instrument for use in nursing homes.
