Construct Validity of the PLS-5

Alexandra Gibson and Elana Winters presented this poster at ASHA’s convention in Chicago in November 2013. Alexandra and Elana created this poster based on work they did in the Assessment and Evaluation course at Teachers College Columbia Uniersity. This course is required as part of the master’s SLP program there.
In that course the students must analyze the most widely used standardized tests to identify disorder/disability for children and adolescents. They analyze the tests’ validity, reliability, and significant biases among other factors. The information for the analysis is primarily from the test itself—generally the interpretive and technical manuals and the other information provided to anyone who purchases the test. That material is analyzed in light of the standards of the field, including the work of Dollaghan, Vance and Plante, Restrepo, and going back to even McCauley and Swisher‘s work of 1984. In the class students find and incorporate into their analysis any research on current or older versions of the test. Another part of the task is to analyze the significant biases including cultural and linguistic biases and biases related to socio-economic background.
