The purpose of the study was to assess the effects of a mental trainin
g program on state anxiety, respiration rate and performance of novice
scuba divers. Forty four participants enrolled in novice open water d
iving courses served as participants. An intervention group (n = 15),
in addition to scuba training, received an audiotaped mental training
program designed to reduce anxiety and improve diving performance. A p
lacebo-control group (n = 15) followed the same procedures except that
their audiotape contained general information about scuba diving. A c
ontrol group (n = 14) received only scuba training. The intervention g
roup reported lower pre-dive scores for cognitive anxiety, higher pre-
dive scores for self-confidence, performed better on bail-out and mask
removal tasks, and showed lower respiration rate than either control
group. Respiration rate and somatic anxiety scores significantly predi
cted bail-out performance. Respiration rate also predieted mask remova
l performance. These results suggest that novice divers may benefit fr
om mental training as part of their pre-dive instruction.
