3. Miami is an international center
of nightclub culture
“Every night is like New Year’s Eve on South Beach, and drugs and sex are all part of it.”

4. Club Drugs Illicit “club drugs” include: Ecstasy Cocaine
Methamphetamine
LSD
GHB
“Designer” stimulants and hallucinogens

5. Background Extensive polydrug use among nightclub attendees
Pervasive resistance to participation in formal interventions
Efficacious interventions to reduce drug use and related consequences are not apparent.

6. The South Beach study
RCT of behavioral interventions to reduce substance use and HIV transmission risk among young adults.

7. The South Beach study Study arms: 1) interviewer-administered (CAPI)
and
2) self-administered (ACASI)
comprehensive health and social risk assessments
3) waitlist control

8. OUTCOME MEASURES Primary Outcomes (past 90 days):
Club drug use frequency
Risky vaginal/anal sex frequency
Measured at baseline and 3-, 6- and 12-months post intervention.

9. Hypothesis
Participants randomized to the CAPI and ACASI intervention conditions will reduce their substance use and related behaviors more than those assigned to waitlist control.

10. The South Beach study Eligibility criteria: Ages 18-39
Past 90 day behaviors
Heterosexual sex
Used “club drugs” at least 3 times
Misused a scheduled Rx drug
Attends large EDM clubs

11. The South Beach study Respondent Driven Sampling N=750
Enrollment

12. MEASURES
Substance use abstinence frequency Substance dependence symptoms: DSM-IV items, including withdrawal symptoms and tolerance (range 1-7). Mental distress symptoms: DSM-IV items assessing past year anxiety, depression and somaticism (range 1-25).

13. Analytical approach Intent to treat basis
Effect size estimates (Cohen’s d)
Log-transformed measures

14. Results
a57 controls missing data (did not complete 12-month assessment)

15. Results
a57 controls missing data (did not complete 12-month assessment); bOne ACASI participant missing data.

20. LIMITATIONS Data are self reported
Eligibility criteria limit generalizability
Diagnostics not clinician-administered

21. Conclusions
Hypothesis partially confirmed – CAPI was superior to control.
Substance dependence and mental distress symptoms below clinically significant levels
Contrary to the hypothesis – ACASI showed lower efficacy compared to control

22. Conclusions Interpersonal interaction appears beneficial
Demonstrates efficacy of single session intervention
Acceptable to target population
No difference between CAPI – ACASI on ‘sensitive’ measures
