The impact of questionnaire purpose (job screening interview vs. consumer survey) and the impact of questionnaire mode (paper-and-pencil vs. computer) on multiple measures of socially desirable responding (SDR) were examined. Students (N= 85) participated in experimental job screening (high SDR demand) and consumer survey (low SDR demand) conditions. Dependent measures included the Marlowe-Crowne Social Desirability Scale and the impression management subscale of the Balanced Inventory of Desirable Responding, Version 6. Significant questionnaire purpose effects suggest one possible, context-related explanation for mixed SDR findings between earlier experiments. Mode effects were nonsignificant, adding further evidence of paper-and-pencil and computer equivalence with respect to SDR.
