Mindfulness is a concept derived from the Buddhist discourses of the Satipattana. Interventions that draw on mindfulness have been shown to reduce psychologically distressing symptoms in clinical settings. It has become widely used as a therapeutic technique in counseling, so it is important to develop an instrument measuring mindfulness-related constructs. This study presents a new instrument measuring the importance of mindfulness-related constructs. Results from an exploratory factor analysis revealed a clear two-factor structure, with the factors named "Present Moment Awareness", and "Compassion and Ethical Behavior." These items were positively correlated with each other and, as expected, negatively correlated with depression. Finally, hours of meditation moderated this association such that the association was stronger among participants who reported higher levels of meditation practice.
