title: RELATIONSHIPS BETWEEN RESPONSE STABILITY AND ITEM ENDORSEMENT, SOCIAL DESIRABILITY, AND AMBIGUITY IN THE MMPI AND THE CPI.
abstract: Relationships between two indices of response stability and item endorsement, social desirability, and seven ambiguity indices were investigated separately within the MMPI, the unique items of the CPI, and two subpools moderate in endorsement and social desirability. Within the two original pools, zero-order correlations and multiple regression analyses revealed that only extremeness of endorsement and social desirability were substantially related to response stability; within the moderate subpools, however, indices of ambiguity-especially item length and ratings of global ambiguity, behavioral reference, and estimated stability-accounted for important degrees of variance individually as well as in combination. Reasons for the moderating effects of endorsement and social desirability are discussed, as are the implications for scale construction.
