Validity and reliability of an instrument for statiscal registration of disability data for physical therapy, 2009
Keywords:
instrument, validity, reliability, physiotherapyAbstract
Introduction: The assessment of such categories as health and disability, requiring the use and standardization of instruments to collect, analyze, reproduce and compare results in a quicker and less empirical form. These tests should also have two essential characteristics: reliability and validity.Objective: Obtain validity and reliability of an instrument for recording in physiotherapy.
Materials and Methods: Methodological, descriptive study, type
instrument validity, including evidence of content validity and reliability. To perform the test of validity 5 physiotherapists (judges) and reliability for testing (n = 60) users in the clinical practice of physical therapy for 3 evaluators rated in two institutions providing health Manizales, similar to the physiotherapy service provided.
Results: Validity of content on the assessment of the experts was obtained by comparison of means, high values was obtained (0.8 - 1.0) for most items, those with low values in their averages were excluded or restructured in the instrument. The tests of reliability yielded a Cronbach alpha of 0.79 in factor clarity and 0.98 for factor significance. Kappa test
of concordance was included to confirm the reliability of the instrument.
Conclusion: An Instrument with good levels of reliability and validity.
