The systematic assessment of vocational interests can be traced to 1927 when E. K. Strong Jr. published the Strong Vocational Interest Blank for Men (SVIB). The SVIB was an empirically based inventory that compared an individual's likes and dislikes to the likes and dislikes of people employed in a variety of different occupations. More than 50 years later, the Eighth Mental Measurements Yearbook ( Buros, 1978) reported that the Strong Inventory was the fourth most frequently used assessment instrument in research, accounting for some 1,720 papers on empirical studies. In their survey of assessment instruments, Brown and McGuire ( 1976) found the Strong inventory to be the eighteenth most frequently used assessment inventory. Engen, Lamb, and Prediger ( 1982) surveyed test use at the secondary school level and Zytowski and Warman ( 1982) assessed the use of tests in private practice, colleges, and universities. The Strong Campbell Interest Inventory was high on both lists. There is no question that E. K. Strong's work has had a profound impact on interest measurement. The third and most recent edition of the SVIB was published in 1981 and is called the Strong Campbell Interest Inventory. A fourth edition was published in 1985. The advances made by the 1985 version of the Strong Campbell Interest Inventory are elaborately discussed by Hansen in chapter 1 of this volume.
A second milestone in the area of interest measurement was the work of G. F. Kuder. In 1934 Kuder introduced the Kuder Preference Record, made up of a series of content scales assessing preferences for specific activities. Kuder's early work was not empirically normed, but in 1966 he introduced the Kuder Occupational Interest Scale, which used empirically defined occupational scales. The most recent revision ( second edition) of the Kuder Occupational Interest Survey occurred in 1979 ( Kuder & Diamond, 1979). A third edition was devel-
