[4] Self-reported physical health outcomes 
Expressive writing also produces longer-term benefits in self-reported health outcomes such as visits to the doctor (Cameron & Nicholls, 1998), physical symptoms (Park & Blumberg, 2002) and number of days out of role because of illness (Pennebaker & Beall, 1986Smyth et al., 2001).

Self-reported emotional health outcomes
Some studies have also found longer-term benefits of expressive writing for emotional health outcomes, including mood/affect (Pennebaker et al., 1988Páez et al., 1999), psychological well-being (Park & Blumberg, 2002), depressive symptoms before examinations (Lepore, 1997) and post-traumatic intrusion and avoidance symptoms (Klein & Boals, 2001).
