Reliability: Current Issues and Concerns

© 2005 Human Kinetics • ATT 10(6), pp. 24-25 THLETIC TRAINERS FIND themselves using a variety of measurements to record their patients’ progress, including traditional paper-and-pencil, computerized, online, and physical (e.g., isokinetics, goniometry) testing tools. Establishing evidence that a treatment or intervention benefits patients forms the foundation of evidence-based practice. Evidence-based practice is the integration of research and clinical expertise in the application of therapeutic procedures.1 A clinician uses procedures and therapies that scientific research has demonstrated to be both reliable and valid. Evidence-based practice has become a central issue in the struggle to demonstrate that certified athletic trainers are effective clinicians. To address the increased need for evidence-based clinical practice, a variety of tools have been developed to assess patient progress. Having an understanding of reliability and validity is important in establishing and selecting the right tool to use. These terms, however, are often misunderstood and used incorrectly. Because reliability and validity are significantly broad topics to examine, this column briefly examines the current issues with respect to reliability only.
