The purpose of the present study is twofold. First, we will attempt to examine the role that emotion regulation and self-presentation play as potential moderators in the expressive writing paradigm. We hypothesize that expressive writing participants who demonstrate greater abilities to regulate their emotions at baseline will improve more on our outcome measures. We also hypothesize that those expressive writing participants who demonstrate higher levels of self-presentation at baseline will improve less on our outcome measures.

The second aim of the study has two related objectives. First, we will attempt to investigate whether the expressive writing intervention can increase and enhance an individual's emotion regulation abilities. Related to this, we will then go on to examine whether emotion regulation can be looked at as a potential mechanism of action in the expressive writing procedure. Related to these two objectives, we hypothesize that in comparison to the control group, participants in the expressive writing condition will show increases in their ability to regulate their emotions from baseline to four week follow up. Moreover, we predict that greater gains in emotion regulation abilities for the expressive writing participants will be significantly related to greater gains in outcome measures.
