Development of a random response scale for the multiple affect adjective check list-revised.

A scale was constructed to identify random responses on the Multiple Affect Adjective Check List-Revised. Items chosen were the 14 least frequently checked items and 14 most frequently checked items, plus the seven most frequently checked negative items and the seven least frequently checked positive items (total=42). The Random Response Scale successfully differentiated random protocols from those produced by 420 college students, and scores on the scale were significantly higher for the college students than for the random sample.
