Social Cultural Factors and Presentation of Self in Different Survey Contexts: Analysis of an Example of Disagreement. A qualitative study among homosexual and bisexual men, who participated in a quantitative study, allows the author to show the effect of survey technique individual responses. Fifteen homosexual and bisexual men, who participated in the French national Gay Press 1995 survey on life styles and homosexual men's reaction to AIDS, were chosen on the basis of their declaration of sexual exposure to risks of HIV infection in the survey's self-administered questionnaire. During the interviews, the replies of a subgroup of those selected proved to be different from responses recorded on the self-administered questionnaire. The analysis of the differences and the comparison of the conflicting and coherent responses shows the impact of social cultural factors on the possibilities of self presentation that is more or less independent of survey context.
