[The validation and usefulness of a questionnaire for evaluating the infrastructure of health centers]

A questionnaire was distributed in all the health centers of the Comunidad Valenciana to establish its validity and usefulness for the evaluation of the physical structure of the health centers. Subsequently, the results were validated by direct verification in 30% of centers. The results of the first part of the questionnaire, related to the type of premises that should be available, and of the second, about the characteristics of such premises, were significantly related with the satisfaction degree (r = -0.724, p less than 0.01), as well as with the criterion of previous planning (p less than 0.001) and the inclusion in structures of a traditional model (p less than 0.001). The 75th percentile of the results of the first and second part of the questionnaire are proposed to select those centers with an unacceptable structure, and, as a quick method, it is recommended to test the parameters of satisfaction degree, previous planning, and inclusion within traditional model structures.
