title: A note on "MMPI scale development methodology".
abstract: Clopton's recent article (1978) in JPA calls attention to methodological problems in the construction of special inventories from the MMPI pool, but overlooks the major problem. It stems from the theoretical correlation between psychopathology and the construct to be measured by the special inventory. This contamination renders the usual validity demonstration questionable. It is pointed out that there is a good number of special inventories that are not subject to the methodological problems noted by Clopton.
