This web-based, cross-sectional survey guided by the Theory of Reasoned Action (TRA), examined behavioral beliefs and normative beliefs associated with smoking tobacco using a waterpipe in a sample of 223 undergraduate college students. Beliefs and norms associated with waterpipe smoking intention were captured using the investigator-developed TRA Waterpipe Questionnaire. Significant behavioral beliefs that contributed to the prediction of smoking intentions included smoking tobacco with a waterpipe "will taste pleasant" and "will allow me to have a good time with my friends." Significant norms that emerged were perceived approval of waterpipe smoking from friends and significant others. Current smoking status, both waterpipe and cigarette, also contributed to the prediction of smoking intention. The variables of the TRA represent prime targets for intervention and provide useful information that can be used to tailor waterpipe prevention messages. © 2012 International Nurses Society on Addictions.
