The study was an investigation of student pilot motivation for, and toward, the Air Training Command's undergraduate pilot training (UPT) program. The motivation hygiene approach was used to identify the motivational factors operating in the UPT program systematically. This approach has been used extensively in industry and with success in a non-training military situation. The purposes of the study were: to employ motivation-hygiene theory and critical incident interview methodology for investigation and motivation in a military training situation, specifically, undergraduate pilot training; and to compare the findings from the undergraduate pilot trainee sample with another air force sample and samples from industrial organizations. Achievement was the factor which appeared most frequently; it was mentioned in 74 of the 90 satisfying incidents and 45 of the 87 dissatisfying ones. The relatively low appearance of two other factors, Responsibility and Work Itself, differs from previous industrial and air force samples. (Author/NL)
