The differential Value Profile (DVP) was first published in the spring of 1963. The instrument grew out of the author's doctoral dissertation in which he reports its method of construction, some underlying psychological theory, its basic validation attempts, and internal consistency. Since its inception, the DVP has been used in many educational research and guidance applications. One of the more significant research applications was conducted by the author to investigate change in student values over four years of college. The results of this longitudinal research are published by the government-supported Project on Student Values, Grand Rapids, Michigan. The DVP was designed primarily for applications at the college and university level. It is a group-research instrument at its present point of development, although many persons are extending its usefulness to individual counseling and clinical applications. It has been simplified for use at the junior high and high school levels. The DVP has demonstrated efficiency in predicting college grades, predicting college drop-outs, assessing particular curricula impact, studying college environments, and various other research tasks.
