The effect of values affirmation on psychological stress.

There is growing evidence for the efficacy of acceptance-based behavioral therapies, which aim to increase acceptance of internal experiences and values-consistent action. Further, experimental studies have demonstrated that acceptance decreases distress and increases willingness to engage in challenging tasks (e.g. Levitt, Brown, Orsillo, & Barlow, 2004). However, research demonstrating the positive effects of values articulation on psychological functioning is needed. The goal of the present study was to evaluate the efficacy of a brief intervention in reducing anxiety related to a stressful speech task. Contrary to predictions, engagement in values writing did not reduce anticipatory or posttask anxiety relative to engagement in a neutral writing task. However, self-esteem significantly predicted anxious response to the task. Experiential avoidance and valued living were also associated with anxious response to the task, although the contribution of these predictors was not statistically significant.
