In his focus article, "Rethinking Traditional Methods of Survey Validation" in this v15 n2 2017 issue of "Journal Measurement: Interdisciplinary Research and Perspectives," Andrew Maul writes that it is commonly believed that self-report, survey-based instruments can be used to measure a wide range of psychological attributes, such as self-control, growth mindsets, and grit. Increasingly, these instruments are being used not only for basic research but also for supporting decisions regarding educational policy and accountability. He questions the validity of the instruments and raises ideas some old and some new about the validation of self-report surveys. In this article, authors, Mijke Rhemtulla, Denny Borsboomb, and Riet van Borkb comment that while they agree with the arguments made in the second half of Maul's paper, they are not convinced that the results presented in the first half of the paper are really damning evidence against the adequacy of psychometric processes.
