Exploring the validity of self-reported Ecstasy use among club rave attendees.

While several empirical studies have focused on Ecstasy use among rave attendees, only one study has explored the validity of self-reported Ecstasy use within this population. To address this limitation, the authors collected self-report drug use information and oral fluid (OF) specimens from 96 club rave attendees within the Baltimore-Washington corridor between August and October 2000. The Kappa statistic is 0.59, suggesting a moderate relationship between the self-report and OF measures. Such accurate reporting bodes well for researchers interested in eliciting sensitive information from this population.
