Group-based Intervention for Club Patrons

The purpose of this study is to develop and test a group-based strategy for encouraging groups of young adults who are engaged in party behaviors at nightclubs to intervene with each other to reduce harms associated with overuse of alcohol and recreational drugs and to reduce harms associated with aggression (physical and sexual).

About this study

This study focuses on high risk behaviors (excessive alcohol use, drug use) and unwanted experiences (physical/sexual aggression) that may occur during an evening at a night club for young adults engaged in party behaviors. the goals were: 1) to develop a screener that accurately assesses a group's level of risk for one specific night of club attendance and based upon this assessment, (2) to provide naturally occurring social groups with the necessary skills to identify vulnerability for and to provide them with tools to reduce harms. An algorithm calculated in real time during an entrance survey predicted the types of risks that the group members may encounter during the evening based upon past behaviors and expectations for the evening. Social groups in the experimental condition were exposed to a brief intervention that focused on developing skills described as the 3 O's: a) Outreach-how to approach fellow group members who are at risk, (b) Options-how to suggest options that would increase safety and (c) Out-How to assess when it is time to leave the club. This brief, interactive intervention was delivered by small tablet computers that utilized mobile application technology and cellular wireless service. This low cost delivery was considered important to providing later adoption in the real world and the interactive nature of the intervention was designed to appeal to the young adult population.

Treatment and study plan

Nightlife Safety Plans (NSP)

Behavioral

A group approach to reducing unwanted outcomes was implemented prior to entering the nightclub. The focus was on peer-to-peer intervention.

Fire Safety

Behavioral

Groups were asked to read information about fire safety prior to entering the club and to answer some questions about fire safety

Primary outcomes

  1. Number of Safety Actions Taken to Intervene Within Group

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.

    Five types of safety actions were assessed for individuals (as they exited the club) that could have occurred in response to peer's use of alcohol or drugs, experiencing physical aggression and/or sexual aggression. These safety actions were: (1) checked in with friends to assess their safety, (2) monitored alcohol consumption of peers, (3) encouraged peer to pace their drinking, (4) discouraged drug use, and (5) encouraged steps to sober up. An individual could report 0-5 safety actions. Because this was a peer group intervention, a mean score was created for each group by adding the total individual scores within each group, (groups ranged in size from 2-9, making this total possible range 0-45) and dividing these total within group scores by the number in the group. Thus, each peer group had a score ranging from 0-5, with the higher the score, the more protective the group was.

  2. Protective Action Reported for Physical Aggression Incident

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.

    Among those who experienced physical aggression, the prevalence of a group member taking action(s) to intervene was reported.

  3. Protective Action Reported for Sexual Aggression Incident

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.

    Among those who experienced sexual aggression, the prevalence of a group member taking action(s) to intervene was reported.

Secondary outcomes

  1. Legally Intoxicated

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.

    Percent who were legally intoxicated (BAC.08% or higher)

  2. Prevalence of Recreational Drug Use

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.

    Any use of recreational drugs present in oral fluid tests based upon lab results

  3. Leaving Club With Friend(s) Arrived With

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.

    Prevalence of safety action to leave club with friends that arrived with

Other outcomes

  1. Experienced Physical Aggression

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.

    While at the club, someone intentionally pushed, shoved, or punched the respondent

  2. Experienced Sexual Aggression

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.

    While at the club, the respondent experienced someone touching them sexually in a way that they did not want to be touched or did something else sexual to the respondent that they did not want them to do

  3. Sexual Harassment

    Time frame: On average, follow up data was collected 1 hour and 54 minutes after baseline (SD 1 hour 3 minutes). The range was from 9 minutes to 5 hours and 15 minutes.
