Individuals responding in a socially desirable (SD) fashion, rather than in a manner that reflects their true behavior, has been a problem for self-report questionnaires since their inception. The purpose of this study was to examine the hypothesis that the probability an item is endorsed on a self-report measure of anger is directly proportional to the rated SD of that item. Eighty-two subjects completed the Buss-Durkee Hostility Inventory (BDHI), the Profile of Moods State (POMS), and the State- Trait Anger Expression Inventory (STAXI). A probability of endorsement was computed for each of the measures' items. Twenty additional subjects rated the measures' items for SD. Each item's SD rating was paired with the probability the item was endorsed to produce a correlation coefficient for each measure. Results strongly support the stated hypothesis. Directions for future research are discussed.
