A Smoking Cessation Campaign on Twitter: Understanding the Use of Twitter and Identifying Major Players in a Health Campaign.

The current study examined the use of online social media for a health campaign. Collecting tweets (N = 1,790) about the recent smoking cessation campaign by the Centers for Disease Control and Prevention, the current study investigated the dissemination of health campaign messages on Twitter and answered questions from the process evaluation of health campaigns: who tweeted about the campaign, who played central roles in disseminating health campaign messages, and how various features of Twitter were used for sharing of campaign messages. Results showed that individuals and nonprofit organizations posted frequently about the campaign: Individuals and nonprofit organizations posted about 40% and 30% of campaign-related tweets, respectively. Although the campaign under investigation was steered by a government agency, nonprofit organizations played a vital role as mediators who disseminated campaign messages. The culture of retweeting demonstrated its particular usefulness for the dissemination of campaign messages. Despite the expectation that the use of social media would expand opportunities for engagement, actual two-way interactions were few or minimal. Drawn from the results, practical suggestions on how to strategize the use of Twitter for future health campaigns are discussed.
