Baikie & Kay Wilhelm Abstract Writing about traumatic, stressful or emotional events has been found to result in improvements in both physical and psychological health, in non-clinical and clinical populations. In the expressive writing paradigm, participants are asked to write about such events for 15–20 minutes on 3–5 occasions. Those who do so generally have significantly better physical and psychological outcomes compared with those who write about neutral topics. Here we present an overview of the expressive writing paradigm, outline populations for which it has been found to be beneficial and discuss possible mechanisms underlying the observed health benefits. In addition, we suggest how expressive writing can be used as a therapeutic tool for survivors of trauma and in psychiatric settings. Over the past 20 years, a growing body of literature emotional experiences (Box 1) for 3–5 sessions, often has demonstrated the beneficial effects that writing over consecutive days, for 15–20 minutes per session. about traumatic or stressful events has on physical Most studies have been conducted in the laboratory, and emotional health. In the first study on expressive writing (Pennebaker & Beall, 1986), college students wrote for 15 minutes on 4 consecutive days about ‘the most traumatic or upsetting experiences’ of their Box 1 Typical writing instructions entire lives, while controls wrote about superficial For the next 4 days, I would like you to write topics (such as their room or their shoes).
