Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 1116 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Group Randomized Trial to Evaluate the Efficacy of Using Pre-dive Checklist to Prevent the Incidence of Recreational Scuba Diving Mishaps
Study Start Date : June 2012
Actual Primary Completion Date : August 2012
Actual Study Completion Date : August 2012

Arm Intervention/treatment
Experimental: Intervention
The intervention group received a pre-dive checklist and a post-dive log
Other: A pre-dive checklist
The pre-dive checklist included a checklist of tasks to be undertaken before the dive, a dive-plan that asked the diver to plan the depth, and amount of gas kept at different levels of diving, and 4 dive tips.

No Intervention: Control
The control group received the post-dive log only.

Primary Outcome Measures :
  1. Mishaps [ Time Frame: One day ]
    Mishaps were reported by scuba divers themselves, at the end of their diving day (the day they were enrolled). Mishaps are precursors of injuries. Injuries are less common outcomes (in fact, nobody got injured), hence we used mishaps - which allowed us to test the efficacy of pre-dive checklists, and do so with limited resources.

Secondary Outcome Measures :
  1. Major mishaps [ Time Frame: One day ]
    Major mishaps are a type of mishaps

  2. Minor Mishaps [ Time Frame: One day ]
    Minor mishaps are a type of mishaps
