The Science of BDSM Data, Phoenix, Arizona, 2014

The goals of this study were to test whether participants who engaged in an extreme ritual in a naturalistic setting would evidence signs of altered states of consciousness, to examine other physiological and affective effects of the ritual, and to determine whether these effects varied based on the role the individual performed within the ritual. A multi-method approach was used that utilized various psychological self-report measures, a measure of cognitive functioning, and a measure of physiological stress. The data collection took place at the "Dance of Souls," a ritual conducted on the last day of the annual Southwest Leather Conference in Phoenix, Arizona, in which participants received temporary piercings with hooks or weights attached to the piercings and danced to music provided by drummers.
The associated publication, Altered States of Consciousness during an Extreme Ritual, was used to accompany the data in this collection. Users are encouraged to consult the publication for additional information. The data collection includes one de-identified dataset with 164 variables for 83 cases. Demographic variables include sex, gender, pierced vs. non-pierced, and the role the participant played in the ceremony.
