This study tested whether the effect of self-referencing in a health-marketing message was amplified or attenuated when combined with message framing and narrative. Hispanic adults (N = 146) were randomly assigned to read and respond to an obesity prevention message. Self-referencing messages generated greater cognitive elaboration but only when placed in a narrative. Conversely, self-referencing messages highlighting health risks of obesity produced higher levels of involvement and intention to increase physical activity and healthy eating. Health marketing professionals can use these findings to enhance the effectiveness of obesity prevention messages that target Hispanic adults.
