An analysis of experimenter effects on responses to a sex questionnaire.

To test whether responses to sex questionnaires vary as a function of the milieu in which the questionnaires are administered, university and college students were presented with an explicit sex questionnaire by a psychologist or by a member of the clergy. In the first study conducted at a nondenominational university, students generally responded similarly when tested by a psychologist, a rabbi, or a priest. There was some evidence suggesting that a greater number of students tested by members of the clergy, rather than by the psychologist, omitted responses to sensitive questions. In a second study conducted at a Catholic college, responses generally were similar when comparing a priest and a psychologist as testers. On one sensitive item, however, there was evidence of an experimenter effect in the predicted direction. Under testing situations common to a number of studies, responses to sex questionnaires seem relatively unaffected by experimenter effects.
