In this paper, I explore how different types of computer interviewers and the amount of self-disclosure from the interviewers affect the quantity of socially desirable responses displayed by interviewees. Online surveys were delivered by computer interviewers. The computer interviewers included a text-based interface and an anthropomorphic character interface. The interviewers' self-disclosure presented their social norm violations. Interview questions were in the form of socially desirable response items representing impression management in this study. The experimental design was a 2 (Interviewers' type) x 2 (Interviewers' self-disclosure versus no self-disclosure) factorial between-subjects experiment. The main dependent variable was whether users' socially desirable responses were affected by the type of interviewer and that amount of self-disclosure provided by the interviewer. The preliminary findings present the potential for self-disclosing anthropomorphic characters to reduce the social desirability bias present in interviewees with high public self-consciousness in their self-disclosure.
