Number of Safety Actions Taken to Intervene Within GroupPrimary· 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 in
