[Development and validation of an instrument to measure the satisfaction of users of rehabilitation services].

Objective: To develop and validate an instrument to measure users' satisfaction of rehabilitation services.

Methods: Literature review to identify main construct domains, elaboration of items, pilot testing to reduce the number of items and redefinition of the questionnaire. The face and content validity were established by rehabilitation specialists. The questionnaire was applied to 85 users of rehabilitation services. The analysis was performed using a principal component factor analysis followed by a varimax rotation, then, the Scree test was used to select significant components and to estimate reliability and validity of the instrument, also Cronbach's alpha coefficient and the split-half test were ascertained.

Results: The final version of the questionnaire consisted of 24 questions. Eighty-five patients answered the questionnaire that was completed in ten minutes on average. The principal components factor analysis and the Scree test detected 8 significant components. Internal consistency of the instrument had a coefficient Cronbach's alpha of 0.80 which was considered as acceptable, and the reliability, by means of the split-half test showed an alpha of 0.72 and 0.69 respectively.

Conclusions: The instrument to evaluate user's satisfaction of rehabilitation services showed to be valid and reliable.
