Intra-individual (attitude) and extra-individual (subjective norm and perceived behavioral control) factors help predict adolescents’ intention to accept friend requests from strangers, but the most influential factor is perceived social pressure exerted by significant others. This study gives overarching guidelines for policy makers who wish to reduce this behavior, with focus being on the involvement of perceived social pressure by significant others. The authors also suggest a mild modification of social networking sites, where a clear reminder would be developed to remind users to think twice before accepting a friend request. Finally the Heirman group mention the possibility of making the default settings of minors with online profiles more private automatically.

Once again, with some modifications, this group of researchers is in support of using TPB as a theory to for a model for a health behavior intervention. There are many other subjects in which the Theory of Planned Behavior is applicable. Some more directly health-related issues that are studied in light of the TPB are medication adherence, continuing education in practitioners, condom use resistance, and HPV vaccine
