“…Although research has not yet been conducted on the impact of expressive writing on stress per se, a metaanalysis found that expressive writing was associated with significant improvements in psychological wellbeing (Smyth, 1998), and a number of studies have also found that expressive writing has important effects on mood, including of reduction of depressive symptoms, anxiety, and psychological distress (Pennebaker et al, 1988;Sloan & Marx, 2004b). On the other hand, more recently a number of studies with negative or equivocal findings have been published (e.g., Broderick, Stone, Smyth, & Kaell, 2004;de Moor et al, 2002), and one metaanalytic review of the literature found expressive writing had limited effects in psychiatric versus medical populations (Frisina, Borod, & Lepore, 2004). To date, no previous study has evaluated expressive writing as an intervention for smoking cessation or examined its effect on perceived stress and affect in individuals who attempt to discontinue smoking.…”
