FFMQ

The Five Facet Mindfulness Questionnaire (FFMQ) is a 39-item self-report measure developed by Ruth Baer through factor analysis of five existing mindfulness questionnaires. It assesses five facets: Observing (noticing internal and external experiences), Describing (labeling experiences with words), Acting with Awareness (attending to present activities), Non-Judging of Inner Experience (non-evaluative stance toward thoughts and feelings), and Non-Reactivity to Inner Experience (allowing thoughts and feelings to come and go). Each item is rated 1–5, with total scores from 39 to 195. The FFMQ is used in psychedelic research as a mediator/moderator variable, testing whether psychedelic-assisted therapy increases dispositional mindfulness and whether baseline mindfulness predicts treatment response. Studies have shown that psilocybin and ayahuasca can produce lasting increases in FFMQ scores, suggesting that psychedelic experiences may enhance mindfulness capacities.
