Defining a “Good” Communimetric Measurement Tool
The quality of any measurement process is defined by at least two essential characteristics—the consistency and accuracy with which the measurement process can be applied and the degree to which the measure is capturing the construct or constructs it is purported to measure. These two related measurement characteristics are commonly referred to as reliability and validity. Given the design approach of a communimetric measurement tool, considerations regarding reliability and validity are distinct but overlapping depending on the use to which the tool is applied. For analyses of aggregated data in which the tool is scored by dimensions, the concepts of reliability and validity are very consistent with traditional psychometric consideration. However, for other applications, the unique characteristics of a communimetric measure require an elaboration of additional considerations about both reliability and validity.
