Expressive flexibility in combat veterans with posttraumatic stress disorder and depression.

چکیده
BACKGROUND A growing body of evidence suggests that the ability to flexibly express and suppress emotions ("expressive flexibility") supports successful adaptation to trauma and loss. However, studies have yet to examine whether individuals that meet criteria for posttraumatic stress disorder (PTSD) or depression exhibit alterations in expressive flexibility. The present study aims to test whether lower levels of expressive flexibility are associated with PTSD and depression in combat-exposed veterans. METHODS Fifty-nine combat veterans with and without PTSD completed self-report measures assessing symptoms of depression, PTSD, and combat exposure. Participants also completed an expressive flexibility task in which they were asked to either enhance or suppress their expressions of emotion while viewing affective images on a computer screen. Expressive flexibility was assessed by both expressive enhancement ability and expressive suppression ability. RESULTS Repeated measures ANOVA's showed that both PTSD and depression were associated with lower levels of emotional enhancement ability. In addition, a series of linear regressions demonstrated that lower levels of emotional enhancement ability were associated with greater symptom severity of PTSD and depression. The ability to suppress emotional responses did not differ among individuals with and without PTSD or depression. LIMITATIONS of the study include a cross-sectional design, precluding causality; the lack of a non-trauma exposed group and predominantly male participants limit the generalizability to other populations. CONCLUSIONS Alterations in expressive flexibility is a previously unrecognized affective mechanism associated with PTSD and depression. Clinical strategies aimed at enhancing emotional expression may aid in the treatment of these disorders.
