The Relationship of the Marlowe-Crowne Scale and its Components to Defensive Preferences

Two lines of recent research have interpreted the Marlowe-Crowne Social Desirability Scale (MC-SDS) as a measure of either need to avoid social disapproval or need to protect and maintain vulnerable self-esteem. In addition, it has been suggested that two component (Attribution and Denial) scores derived from the MC-SDS are differentially related to defensiveness. The present study tested several hypotheses regarding the relationship of the MC-SDS and its components to relative preference for five classes of defensive responses, as measured by the Defense Mechanisms Inventory. Results among females best supported a disapproval-avoidance interpretation of the MC-SDS. while no support was found for the proposed differential validity of the attribution, and denial components. Support for such differential validity was, however, obtained among males. Results for this group suggest that high denial component scorers will opt for protecting vulnerable self-esteem even in the face of possible social disapproval, while high attribution scorers are primarily concerned with avoiding such disapproval. Implications for use of the MCSDS and its components as measures of defensiveness are discussed and suggestions for additional research are presented.
