“…Many studies offered no clear definition of relapse, although it was generally inferred from the description of the subject's smoking status (Bottorff, Johnson, Irwin, & Ratner, 2000; Carmichael & Ahluwalia, 2000; Gantt, 2001; LeLong, Kaminski, Saurel‐Cubizolles, & Bouvier‐Colle, 2001; MacLean, Estable, Sims‐Jones, & Edwards, 2002; Piasecki, Fiore, McCarthy, & Baker, 2002; Pickett, Wakschlag, Dai, & Leventhal, 2003; Pomerleau, Brouwer, & Jones, 2000; Rice, Fotouhi, Burn, Hoyer, & Ayers, 1997; Wilemsen, Hoogenveen, & Van der Lucht, 2002). Examples of this include questioning participants if they quit for >1 week and identifying those who also answered yes to currently smoking as relapsers (Pickett et al, 2003) or merely asking the question smoking or not smoking at various points in a longitudinal study to derive relapse statistics (Lelong et al, 2001).…”
