How to Measure Survey Reliability and Validity

Improving the accuracy of a survey is the focus of Mark S. Litwins book which shows how to assess and interpret the quality of survey data by thoroughly examining the survey instrument used. He explains how to code and pilot test new and established surveys. In addition he covers issues such as: how to measure reliability (including test-retest alternate form internal consistency inter-observer and intra-observer reliability); how to measure validity (including content criterion and construct validity); how to address cross-cultural issues in survey research; and how to scale and score a survey.
