Study type
Description of intervention(s) / exposure
Research Group: Within one 50-minute session, the participant explores his/her ecstasy use and values. The specialist then offers feedback regarding the participant's use and provides participants with practical skills for reducing use. Suggestions are made that are in line with the participant's values. It is the decision of the participant to use these skills or not, and they are not pressured to quit or reduce their ecstasy use.

Comparator / control treatment
Participants will be randomly allocated either to the Ecstasy Check-Up discussion (Research group) or education-only discussion (Control Group). Participant's in the control group, receive an educational factsheet that contains the latest facts about ecstasy. They will be given up to 15 minutes to discuss the factsheet with the E-check-up specialist. Participant's in the research group receive the educational factsheet, along with feedback from their assessment. Participants in the research group spend 50 minutes discussing their ecstasy use, feedback, and values.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Recruitment efforts will involve advertisements in the free street press and postings on a range of relevant websites.

Fliers will be distributed to university campuses and music venues. When potential participants initially make contact, they will be screened for eligibility, usually by telephone. Those who are ineligible or do not consent to participate in the study will have their details kept for reporting on the reasons for ineligibility.

When participants appear to meet inclusion criteria, an appointment will be made for a face-to-face discussion about Ecstasy use and values. E Check Up Specialists who complete the baseline assessments are blind to study condition. Sealed opaque envelops, which contain the randomised condition, are not opened until after a participant is deemed eligible for study inclusion.

Brief summary
Our long-term goal is to decrease ecstasy use in Australia by motivating ecstasy users, through brief and early information and discussion, to reduce their use through providing research based information and discussion. The objective of the proposed research is to evaluate a brief discussion based on motivational interviewing (Ecstasy Check-Up) for regular ecstasy users (1 session) compared with an educational control discussion, which involves provision of an informational booklet regarding the facts and fiction on ecstasy use.

The primary hypothesis of the proposed study is that the one-session brief motivation interviewing discussion will be associated with lower levels of ecstasy use and dependence than the education only discussion. E Check Up sessions in which the specialist more strongly adheres to motivational interviewing principles are expected to have better outcomes.

Additionally, our secondary hypothesis is that participants in the study will like and gain some positive aspects from both conditions, regardless if they have been assigned the research or the education discussion.

The research is of benefit to participants as it offers an opportunity for them to manage their ecstasy use. This lifestyle change has many benefits including improvements in physical and mental health. This benefit, however, cannot be guaranteed; it is dependent on participants’ engagement with the discussion.

At the baseline session, all participants will be assured that any information they provide will remain strictly confidential (within the limits of legal confidentiality and duty of care). After written informed consent is provided and all questions and concerns have been answered, the baseline assessment will occur.

At one-, four-, and six-month follow-ups the research assistant will conduct face-to-face follow-ups with all participants using the measures collected at the baseline assessment. The outcome measures will be modified to assess the relevant durations at each visit. For example, the measures will assess the last 90 days during the baseline assessment, and the past 30-days at the one-month follow-up.
