To evaluate the efficacy of using a pre-dive checklist to prevent the incidence of diving mishaps in recreational divers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
A pre-dive checklistOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Intervention | Experimental | The intervention group received a pre-dive checklist and a post-dive log Receives: Other: A pre-dive checklist |
| Control | No intervention | The control group received the post-dive log only. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mishaps
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.
Measured: One day

Major mishaps
Major mishaps are a type of mishaps
