Assessment has 48 likert scale items, using 7pt agreement scales. I have performed CFA with a validation set of 287 respondents. I'm using deviation IQ to transform the scores. However, I noted that some respondents tend to answer all in the 6 or 7s, or all 3s. Or all 1s and 2s. I have read a few articles on ESR and ASR, but I'm not sure how to actually apply the theory to actual data and correct for these forms of bias. So, I already have the data. This would be a retrospective correction. I'm frankly not even sure it's needed. I'm not sure what the standard practice is in psychometrics.
