Operationalization
51 volunteers had completed 5 weeks of basic recruit 
training and spent next 4 weeks in special 
pre-Underwater Demolition Team training program; on the 
basis of test results at the end of week 4 of the 
training men were divided into pass and fail groups. 66 
volunteers had also completed 5 weeks of basic recruit 
training and spent next 4 weeks in the Recruit Training 
Center choir program (control group).

Groups:

b. Fail
c. Control

Underwater demolition team (UDT) training is a 4 month 
program with attrition rate of trainees between 30% and

pretrain volunteer naval recruits during their last 4 
weeks of a 9 week basic recruit training program.
