Upper Saddle River, N.J.: Pearson/Prentice Hall. This is when a study splits the test into two parts and measures the stability between measurement items in both test halves. Reliability and validity are closely related, but they mean different things. Reliability is the presence of a stable and constant outcome after repeated measurement or test. If the same result can be consistently achieved by using the same methods under the same circumstances, the measurement is considered reliable. In experiments, you can achieve high reliability by repeating the experiments several times. Objective: To develop a Spanish version of the international Hip Outcome Tool questionnaire (iHOT-12Sv) for assessing the psychometric characteristics (internal consistency, convergent validity, test-retest reliability, and floor and ceiling effects) of this version in physically active patients with hip pain. The author explored the extent to which current factor analytic methods and other techniques for establishing validity are consistent with best practices, as well as reliability and validity evidence from instrument development articles reporting the application of exploratory factor analysis and principal component analysis.

There are different forms of research validity and main ones are specified by Cohen et al (2007) as content validity, criterion-related validity, construct validity, internal validity, external validity, concurrent validity and face validity. There are two distinct criteria by which researchers evaluate their measures: reliability and validity. True or False: By usingmultiple forms of similar tests, a researcher can indicate whether the measurement is reliable depending on the consistency of an outcome. Each type can be evaluated through expert judgement or statistical methods. The University of Mississippi. Reliabilty and Validity Topics. Split-Half Reliability.
