Response Shift Bias: An Examination Of Measurement Invariance In Self-Reported Change, Katherine Nelson Daniels

Dissertations

Traditional pre-test (TpT)/post-test (PT) and retrospective pre-test (RpT)/post-test (PT) designs are used to collect data on self-reported measures to assess the magnitude of change that occurs from interventions. If measurement invariance does not exist across the measurement occasions within these research designs, it is inappropriate to compare mean group differences that result from the intervention and derive inferences about change. The theory of response-shift suggests a subject’s understanding of a subject matter at TpT may not be the same as their understanding of a subject matter at PT, and that as a result, the construct measured at these measurement occasions …
