The purpose of this study was to evaluate if a single session mindfulness-based art therapy doodle intervention may support and improve: (a) mindfulness, (b) mindful creativity, and (c) positive and negative emotional states. A general community sample of 71 adult participants engaged in the mindful doodling virtual two-hour workshops. Based on retrospective methods from participant self-reported perceptions before and after the workshop, there were statistically significant increases in ratings of mindfulness, mindful creativity, and positive emotions, as well as decreases in negative emotions (p < 0.05). The results suggested the potential efficacy and clinical benefit of this single session art therapy intervention for promoting mindfulness, creativity, and positivity in the community.
