This study investigated the usefulness of desirability judgments of personality items as an indirect measure of the judge's personality.Self-reports and judgments were compared on separate forms of five personality scales. With a few striking exceptions, the two kinds of measures were generally unrelated, and they had markedly different patterns of correlations with behavioral measures of conformity. In general, self-reports only correlated with conformity for subjects who were unsuspicious about the conformity procedures, but judgments correlated with conformity for unsuspicious and suspicious subjects. Both self-reports and judgments correlated with response styles and intelligence, but the self-reports were more extensively involved with the response styles. The differential functioning of the two kinds of measures could not be attributed to the operation of response styles or intelligence, nor did these latter variables moderate the relatiunship between self-reports and judgments.
Desirability Judgments and Self-Reports as Predictors of Social Behavior lInterest in alternatives to self-report measures of personality traits and attitudes has increased in recent years (Campbell, 1950; Cattell, 1957; Cook & Selltiz, 1964;Webb, Campbell, Schwartz, & Sechrest, 1966;Weschler & Bernberg, 1950), fostered by the growing criticism of many widely used self-report scales and inventories. The criticism of self-report devices centers around their limited construct validity and their susceptibility to the various biases that occur when people attempt to describe themselves.One approach to II indirect '1 (Campbell, 1950;Weschler & Bernberg, 1950) or "objective ll (Cattell, 1957) assessment, an approach that employs subjects' judgments of the favorability or desirability of questionnaire items, has stimulated research in the personality and attitude domains.The work in the two areas, though proceeding along similar lines, has developed quite independently. Although there were precursors (cf., Campbell, 1950), the impetus for the attitude research was Hovland and Sherif's (1952) well-known methodological investigation of Thurstone attitude scaling, which found that Negroes, pro-Negro whites, and antiNegro whites gave different ratings of favorability to attitude items concerning Negroes. Among the subsequent studies of this kind in the attitude area (e.g., Atkins, 1966;Ostrom, 1966;Prothro, 1955Prothro, , 1957Segall, 1959;Upshaw, 1962;Ward, 1966;Weiss, 1959), only the research by Cook and his associates (Edrich, Selltiz, & Cook, 1966;Selltiz, Edrich, & Cook, 1965;Zavalloni & Cook, 1965) explicitly explored the validity of favorability ratings as an indirect attitude measure.-2-Research employing jud~nents as indirect measures of personality has been influenced by two kinds of findings. One was the pioneering work by Edwards (1953) and Gordon (1953) that uncovered correlations of .87 and .96, respectively, between the favorability or social desirability of personality items and their frequency of endorsement.
