A self-description essay procedure was employed to ascertain the degree to which self-disclosing behavior would be predicted by scores on the Jourard Self-Disclosure Questionnaire and by scores on the Marlowe-Crowne Social Desirability Scale (SDS). Data from 56 college women revealed relationship whatever between Questionnaire scores and judges' ratings of self-disclosure; a significant negative relationship was obtained between SDS scores and the self-disclosure ratings. Judges' liking for the respondent and respondent verbal fluency were found to be substantially associated with the ratings of self-disclosure. Some implications of the present results for the concept and assessment of self-disclosure are discussed. In his widely known book, The Transparent Self, Jourard (1964) called attention to selfdisclosing behavior as an important factor in personal growth and interpersonal relationships. For Jourard, meaningful self-disclosure consists of communication of my private world to you in language that you clearly understand [p. 5]. Such communication is seen as particularly vital in the sense that no man can come to know himself except as an outcome of disclosing himself to another person [p. 5]. This view is embodied in the widely held psychotherapeutic premise that a patient's authentic self-revelations are accompanied by an increasing awareness of submerged thoughts and feelings. In order to assess the degree to which an individual typically makes himself known to others, Jourard and Lasakow (1958) developed a Self-Disclosure Questionnaire which requires the respondent to estimate, by means of scalar ratings, the extent to which he usually discloses his thoughts and feelings about various topics (e.g., personality, money, attitudes) to various persons (e.g., mother, father, friend). As might be expected, amount of reported selfdisclosure has been found to vary with the ego-relevance of subject matter, the relationship between the respondent and the person to whom he discloses, and respondent charac
