Reliability and Validity Assessment

This guide explains how social scientists can evaluate the reliability and validity of empirical measurements, discussing the three basic types of validity: criterion related, content, and construct. In addition, the paper shows how reliability is assessed by the retest method, alternative-forms procedure, split-halves approach, and internal consistency method.

This guide demonstrates how social scientists assess the reliability and validity of empirical measurements. This monograph is a good starting point for those who want to familiarize themselves with the current debates over "appropriate" measurement designs and strategies.
