| Ecstasy use is unhealthy but widespread, and many users do not apply the recommended harm reduction practices. Laws forbidding ecstasy use are apparently inefficient in restricting use, and do nothing to promote the application of harm reduction practices. A health promotional intervention may prove effective in these respects. The effectiveness of such interventions is facilitated by planned development, as prescribed by the Intervention Mapping protocol. A number of studies designed to systematically garner information that facilitates effective intervention development are conducted. Then, the intervention is developed by applying the methods and strategies evidenced to be effective in changing those determinants that were found to influence the relevant behaviours. Finally, the intervention is evaluated. |
