DESCRIPTION: Researchers and clinicians rely on measurement to understand, evaluate, and differentiate individuals' physical and behavioral characteristics. In clinical, epidemiological, and social research, it is common to measure characteristics that are not directly observable, such as blood pressure, stroke volume, anxiety, and pain. The value of these measurements in research and clinical practice depends on their reliability, i.e., the degree to which they are consistent and free from error. Therefore, reliability is a critical prerequisite for any measurement to be useful.
In medicine, researchers often want to compare different methods of measuring a characteristic to determine whether a new, quicker, or more affordable method agrees sufficiently well with an established method for clinical purposes. Commonly used statistical techniques such as comparison of means or correlation analysis, do not answer whether the methods provide the same measurements on average or if there is any relative bias.
This seminar will provide a brief overview of commonly used techniques to assess reliability. It will cover statistical methods and related procedures to evaluate reliability according to the type of measurement and the nature of the response scale. Examples from clinical and public health research will be used to demonstrate data analysis, including discussions on the necessary syntax and interpretation of the resulting outputs. By the end of the seminar, participants will be able to conduct appropriate statistical analyses and interpret outputs to evaluate reliability data.
