Psychological attributes of South African Navy Underwater Sabotage Device Disposal operators

The first of two studies described here aimed to determine the extent to which psychological instruments could be used to describe the psychological profile of Underwater Sabotage Device Disposal (USDD) operators in the South African Navy. The Advanced Progressive Matrices, 16-Personality Factor Questionnaire (16PF), Self-Directed Search Questionnaire, and Rey Complex Figure Test were used. In this study, five 16PF factors appeared to be most descriptive of the sample. They were adventurous, assertive, self-assured, emotionally stable, and tough minded. These factors appeared appropriate when discussed from an environmental demand perspective. Occupational interests were realistic and social, and operators scored high on the Complex Figure Test. The second study aimed to determine the extent to which the 16PF could differentiate between USDD operators and other clearance divers. Two factors showed a significant difference between the two groups. The USDD operators were more adventurous and more assertive, which also appeared appropriate when discussed from an environmental demand perspective.
