The final report on the development of a Work-Relevant Attitudes Inventory (WRAI) describes the use of the WRAI in diagnosing the needs of individuals and evaluating the effectiveness of manpower programs. The WRAI was used in two longitudinal studies: four Neighborhood Youth Corps (NYC) programs with 502 subjects, and a demostration education project, the New Educational Program, with 526 subjects. The WRAI was able to differentiate between subjects making a "good" and a "poor" adjustment to work. Furthermore, positive changes in WRAI scores were associated with a "good" adjustment. The WRAI also correlated with counselor ratings and with achievement test scores in reading and mathematics. It was concluded that the WRAI had demonstrated its usefulness as a measure of program effectiveness and as a help in diagnosing the needs of new program participants. Five appendixes include the WRAI and various statistical measures relating to the results of its administration. (Author/JR)
