Abstract

Objective: The study re-examined the validity and reliability of the Physical Therapy Outpatient Satisfaction Survey (PTOPS) using a geographically different and larger patient population, random sampling, and mail survey methodology. Background: Measurement of patient satisfaction in physical therapy is in tis infancy. Development and refinement of theory and measurement methodology are imperative. Replication of reliability and validity is an important component of questionnaire development. Design: This study used a methodological design with descriptive elements. It employed a survey of a random sampling of subjects from 20 outpatient clinics throughout the Gulf South United States. Method: 2,309 patients 21 years of age or older who lived in Mississippi, Alabama, Florida and Louisiana were mailed PTOPS questionnaire, yielding 1,175 usable responses and a 60% usable response rate. Principal components analysis explored the dimensions of satisfaction, and Cronbach alpha scores investigated inter-item reliability. Regression analysis investigated predictive validity. Results: The construct of four original dimensions found in the PTOPS (Enhancers, Detractors, Costs, Location) remained consistent with this sample and methodology. Cronbach alpha scores indicated high levels of inter-item reliability. Regression analysis suggested that all four dimensions were predictive of overall patient satisfaction. Conclusion: The PTOPS retained excellent reliability and validity when used in a different locale, with a mail survey methodology, and when using retrospective study techniques.
