title: Two-sided messages for health risk prevention: the role of argument type, refutation, and issue ambivalence.
abstract: Two experiments were conducted among adolescents in 2011 in urban parts of Belgium, Europe. The effectiveness of two-sided binge drinking and marijuana prevention messages was investigated in relation to argument type, refutation, and issue ambivalence. Study 1 (n = 373) serves as a baseline study for study 2 (n = 156). Data were collected through a printed questionnaire in classrooms in Flemish secondary schools. Analysis of variance (ANOVA) was used to analyze the data. Implications for health practitioners, as well as limitations and suggestions for further research are given.
