The purpose of this study was to examine if messages tailored to an individual's regulatory focus (i.e. their tendency to focus on prevention or promotion) increased exercise intentions and behavior in a medically underserved sample. Adult English as a Second Language students (N = 58) were presented with tailored exercise messages. There was a significant main effect for message type; participants who received promotion messages reported greater exercise intentions than those who received prevention messages. Intentions and behavior were not higher among those who received messages matching their regulatory focus. Implications for message tailoring frameworks are discussed.
