title: Comparisons of performance effectiveness among divers.
abstract: Using a criterion of performance effectiveness derived from actual dives made under operational conditions, comparisons were made between U.S. Navy divers identified as high and low in performance effectiveness. Comparison measures included intelligence, anxiety, disciplinary problems, and incidence of decompression sickness (DCS). As expected, the most effective divers made more frequent and more hazardous dives than the least effective divers. In addition they had fewer diving accidents and a lower incidence of DCS. While the most effective divers had lower intelligence scores than the least effective group, both groups were substantially above the Navy average. These findings indicate that intelligence appears to be a critical variable in the career retention of divers, as well as the frequency and types of dives to which divers are exposed. The higher incidence of diving accidents and complications, especially DCS, found among the least effective divers may also have been involved in the lower frequency of diving observed among the members of this group.
