The purpose of this study was to examine the effectiveness of gratitude interpretation bias training in decreasing narcissism. This is important because of gratitude’s consistent ability to increase subjective well-being and improve relationships. Because narcissism has been shown to inhibit gratitude, decreasing narcissism by establishing gratitude interpretation biases may have a number of benefits. The effectiveness of these trainings in increasing positive emotions should be researched in terms of decreasing negative emotions, like those associated with narcissism. I found that the trainings significantly influenced participants’ interpretations of ambiguous benefit-related scenarios. However, the intervention did not significantly impact the other outcome measures. I conclude that interpretations of a benefit can indeed be modified through CBM-I training.
