Hello, I have a data set with multiple scales (Demographics, Identification, Attitudes), each composed of 6 items each (Demographic: D1-D6; Identification: I1-I6; Attitudes: A1-A6). I am noticing many of the participants entered the same value (all 4s or all 5s) for all the questions within the same scale (all 4s for Demographic and all 5s for Identification).

I would like to screen these participants out. Is there a way I can select participants who have entered the same value for all items (D1-D6) within a scale (demographics)? Note that I don't want to screen out any one specific value, it could be all 4s or all 5s, the specific number is not important but the consistency of the same number for every question within the scale is the problem. If I have multiple scales, would I have to do something different? ... View more
