“…PME measures can take various forms. For example, participants have been asked to respond to questionnaire items asking for ratings of messages on persuasiveness, convincingness, effectiveness, and the like (e.g., Mackert et al, 2014;Popova, Neilands, & Ling, 2014), to rank-order messages in terms of persuasiveness (e.g., Mouneyrac, Le Floch, Lemercier, Py, & Roumegue, 2017;Pollard et al, 2016), or to engage in focus-group discussions concerning relative message persuasiveness (e.g., Mowbray, Marcu, Godinho, Michie, & Yardley, 2016;Record, Harrington, Helme, & Savage, 2018). For some general discussions of such measures, see Choi and Cho (2016), Noar, Bell, Kelley, Barker, and Yzer (2018), and Yzer, LoRusso, and Nagler (2015).…”
