Preventing Alcohol and Drug Overuse Among Nightclub Patrons

Preventing Alcohol and Drug Overuse Among Nightclub Patrons

Nightclubs are high-risk settings for overuse of alcohol and other drugs. In a July publication in the Journal of Studies on Alcohol and Drugs, collaborators from the Pacific Institute for Research and Evaluation (PIRE), the University of California San Francisco, and Klein Buendel reported the outcomes of their intervention to protect nightclub patrons from substance abuse and harmful consequences.

Nightlife Safety Plans (NSP) is a group-based, tablet app-delivered intervention designed for groups of patrons arriving at nightclubs together. NSP encourages social groups to recognize early indicators of risk and take actions steps to de-escalate risky situations, such as physical and sexual aggression, through peer influence and other methods. The intervention was designed around a simple mnemonic – the three O’s: Outreach, Options, and Out:

  • Outreach: “provide outreach by approaching the friend and checking in, using nonconfrontational approaches”
  • Options: “provide options to a group member if a problem is identified”
  • Out: “know when the group should get out of the club to avoid further problems”

A total of 959 people from 352 social groups participated in the intervention at 41 different electronic music dance events at nightclubs in San Francisco, California. The measures (including breath samples for blood alcohol concentration and oral fluid samples for drug use), methods, analyses, results, discussion, and limitations are detailed in the publication.

In summary, intervening in the right place at the right time with peer influence strategies proved to be effective. The authors report that the NSP app appeared to increase protective actions to keep group members safe from overuse of alcohol and other drugs in these high-risk environments.

This research was funded by a grant to the Prevention Research Center at PIRE from the National Institute on Alcohol Abuse and Alcoholism (AA022331; Dr. Brenda Miller, Principal Investigator). Authors of the publication include Dr. Hilary Byrnes, Dr. Brenda Miller, Dr. Mark Johnson, and Veronica Rogers from PIRE; Dr. Beth Bourdeau from the University of California San Francisco; and Dr. David Buller and Julia Berteletti from Klein Buendel. The NSP tablet app was developed by Klein Buendel’s Creative Team.

Nightlife Risk from Alcohol and Drug Use

Nightlife Risk from Alcohol and Drug Use

Two Klein Buendel researchers are part of a team that presented two posters at the Society for Prevention Research Annual Meeting in San Francisco in May. Dr. David Buller and Julia Berteletti are part of the Nightlife Safety Plans research team led by Dr. Brenda Miller from the Prevention Research Center at the Pacific Institute for Research and Evaluation (PIRE).

Nightclubs are high-risk settings for overuse of alcohol and other drugs and physical and sexual aggression among young adults. Nightlife Safety Plans (NSP) is a group-based, tablet app-delivered intervention designed for patrons arriving together. NSP addresses these unwanted outcomes and encourages social groups to recognize early indicators of risk. Actions steps are provided via tablet app to de-escalate the situation. 

Nightclub Group Gender Composition

The first poster examined the influence of social group gender composition on alcohol outcomes and on the effectiveness of the NSP intervention across different group compositions (all-female, all-male, mixed gender). The sample included 959 nightclub patrons who formed 359 groups recruited from seven clubs, across 41 different events. Less than half of the participants were female and the average age was 26. All data was collected anonymously.

Outcome variables included overall number of the group’s safety actions taken to keep group members safe, the highest number of safety actions by any single group member, and breath alcohol concentration (BAC) at exit.  Mixed model regressions examined the main effect of group composition and its interaction with the intervention as a predictor of outcomes after controlling for individual and group characteristics. Those in the intervention condition reported higher numbers of safety actions by any single member in all female groups and mixed gender groups, but not in all-male groups. There were no significant interactions for intervention status by group composition for either BAC at exit or the number of group actions taken as assessed by the overall group.  This poster was first-authored and presented by Dr. Brenda Miller from PIRE.

Drinking Group Cohesion

The second poster examined the hypothesis that club patrons who perceive greater cohesion in their group implement fewer protective strategies and use higher levels of alcohol and other drugs. Could being part of a more cohesive peer drinking group lead to a false sense of security and letting down one’s guard, which could lead to more risk taking? The sample included 815 nightclub patrons in the San Francisco area, arriving in 324 distinct groups, from seven clubs hosting electronic music dance events across 30 different evenings. Less than half of the participants were female and the average age was 27. Club patrons were surveyed anonymously and completed breath tests as they entered and exited clubs. Oral fluid samples at exit assessed drug use.

Patrons reported perceived cohesion with their group members (for example, people in the group are willing to help each other), as well as use of actions to keep oneself safe, actions to keep group members safe, and actions in response to group alcohol and other drug problems. Mixed model regressions examined group cohesion as a predictor after controlling for individual and group characteristics, and past 30-day drinking/drug use at clubs. Findings partially confirm the hypothesis. Patrons who perceived greater group cohesion engaged in fewer preventive strategies to keep themselves and their group safe during the night and those who perceived greater group cohesion implemented fewer actions in response to group AOD problems. This poster was first-authored and presented by Dr. Hilary Byrnes from PIRE.

Nightlife Safety Research

Nightlife Safety Research

Dr. Brenda Miller from the Pacific Institute for Research and Evaluation (PIRE) gave a presentation at the 9th Conference and Members’ Meeting of the European Society for Prevention Research (EUSPR) in Lisbon, Portugal, October 24-26, 2018. EUSPR “promotes the development of prevention science, and its application to practice so as to promote human health and well-being through high quality research, evidence based interventions, policies, and practices.” The research presented by Dr. Miller was designed and conducted in collaboration with scientists and staff from Klein Buendel (KB).

The study of nightclub patrons and their social drinking groups, tests an intervention called Nightlife Safety Plans (NSP). NSP is designed to reduce escalation of overuse of alcohol and drugs, physical aggression, and sexual aggression during an evening at the club. NSP relies on social groups that arrive at the club together to identify early signs of problems and to take actions to intercede. The actions are: Outreach, Options, and Out.

Data analyzed in this presentation consisted of 352 groups (961 participants) gathered over 41 Friday and Saturday nights at seven different clubs in the Bay Area of California. Data from online surveys, alcohol breath tests, and biological drug tests (post-test only) were gathered at entrance and exit for pre- and post-test assessments of the intervention effects. Biological measures reveal at least one club patron per group was legally intoxicated (Breath Alcohol Concentration—BAC, >.08%) in 60% of groups and at least one patron was positive for drugs in 50% of the groups. Further, at least one club patron per group experienced physical and/or sexual aggression within 40% of the groups.

Results indicated that experimental groups were significantly more likely to intervene with group members, using a significantly higher number of intervention strategies (Outreach, Options, and Out), to assess situations for physical aggression and sexual harassment, and to respond to friends experiencing sexual harassment. Further, experimental groups used significantly more protective strategies to keep group members safe. Reduced levels of alcohol use and intoxication or impairment (BAC > .05), as assessed by breath tests, were found among the groups in the experimental as compared to the control condition.

In summary, groups provide an opportunity to deliver and implement peer-focused safety strategies to enhance safety during the time spent in the club. The research’s focus on clubs also reaches young adults who are working (two-thirds were not in college), whereas many of these types of interventions are targeted toward college students.
