This article discusses the influence of message credibility and the pressure to hide tobacco consumption in regard to the “Bogus Pipeline.”
Abstract
Bogus Pipeline is a frequently used resource to increase the honesty of self-reports of tobacco consumption among adolescents. The basis of this technique is if subjects are convinced that the evaluator has a machine or method for physiologically measuring that infallibly proves real behavior, then the honesty of their self-reports increases. Participants were 504 students from 3 middle schools in Granada, Spain. There was random assignment of 18 classes to 6 experimental conditions: Bogus Pipeline with video presentation and anonymous questionnaire; Bogus Pipeline with oral presentation and anonymous questionnaire; Bogus Pipeline with oral presentation and named questionnaire; without Bogus and with anonymous questionnaire; and without Bogus and with named questionnaire. Results showed that, according to the role of message credibility, there was a superiority of the video presentation over oral presentation. This means of presentation should become the standard protocol for carrying out the technique. Regarding the pressure to hide consumption, results confirm that the technique Bogus Pipeline was especially effective in the presence of such pressure and that in its absence only led to a slight increase in the validity of self-reports. The Bogus Pipeline technique is effective when given the condition that the technique’s logic itself demands, namely the existence of pressure to hide tobacco consumption. Its application is recommended in those situations where the existence of such pressure is presumed and always with a video presentation. 2 tables, 21 references
