Rasch 모형을 이용한 Marlowe-Crowne의 사회적 정향성 척도 타당화

초록

The present study investigated the psychometric properties of the Marlowe-Crowne social desirability scale. Social desirability refers to the tendency for individuals to present themselves in ways of socially favored fashion (Crowne & Marlowe, 1960, p.353). Specifically, the purpose of this study were to test the validity of items by examining dimensionalities of the questionnaire, and to examine the consistency of the participants' responses using the Rasch model. For this purpose, all the original 33 items were translated into Korean and administered to the 286 college students. The followings are the summary of the major findings; First, the mean and standard deviation of the Korean version of the Marlowe-Crowne scale are 14.47 and 4.88 respectively, which are similar to the findings reported by Marlowe-Crowne(1960) in their original study(M=13.72, SD=5.78). Second, the reliability coefficient was α=.73, that implies an acceptable level of reliability. Third, the results of residual based factor analysis indicated that the instrument has a unidimensional structure, which is consistent with the basic assumption of the Rasch model. All the findings in the present study suggest that the Korean version of the Marlowe-Crowne scale is a psychometrically sound research tool, and thus, can be used in the future studies.
