[Evaluation of patient satisfaction after stroke rehabilitation program. Validation study for the Spanish version of the Satisfaction Pound Scale]

Abstract

Background and objective: The Satisfaction Pound Scale is a specific questionnaire to evaluate satisfaction with the rehabilitation program after a stroke. The aim of this study was to adapt this scale to Spanish and to evaluate its metric characteristics.

Method: The adaptation included translation and back-translation methods. Metric characteristics were evaluated in 74 patients, all of whom were administered the Satisfaction Pound Scale and the Short Form 36 (SF-36). The statistical model was tested by confirmatory factor analysis (CFA). Reliability was determined through Cronbach alpha coefficient and a test-retest procedure. Construct validity was assessed by means of correlations between the satisfaction scale and the SF-36.

Results: Adjustment indicators in the CFA were very good. Reproducibility test showed correlations higher than 0.85, and all correlations between SF-36 dimensions and the satisfaction scale were lower than 0.2, in accordance with the hypotheses raised.

Conclusions: The Spanish version of the Satisfaction Pounds Scale is reliable and valid, therefore it is a useful tool to assess satisfaction with the post-stroke rehabilitation program in our area.
