Pilot RCT Results of Stop My Smoking USA: A Text Messaging–Based Smoking Cessation Program for Young Adults

Abstract

Consistent with pilot studies, the sample was underpowered. Data suggest, however, that the SMS USA program affects smoking cessation rates at 4 weeks postquit. More research is needed before conclusions can be made about long-term impact. Identifying profiles of users for whom the program may be particularly beneficial also will be important.
