CROET's program to develop effective individual training methods for occupational safety and health continued to grow in 2002. Our computer-based training program, cTRAIN, was developed by Dr. Kent Anger, CROET Associate Director, and Dr. Diane Rohlman in collaboration with Mr. John Kirkpatrick of the Painters District Council. Research continued on the basic principles underlying training, an area almost devoid of research in working adults, demonstrating again the superiority of interactive training (quizzing during training with immediate feedback on answer accuracy). Quiz frequency appeared to be important for some material, with accuracy on the post-test declining in a program with up to 17 screens of information prior to a quiz, but not in programs with more frequent quizzes. Interestingly, open-book quizzes during training produced slightly better recall than closed-book quizzes, when evaluated later by a closed-book test. New programs for drywall finishing (ergonomic and other issues), lab safety, and food handling were developed and began field testing. The food services safety and health content program increased knowledge of fire safety and hazards such as those leading to slips and falls.
