to personality characteristics, such as dogmatism (i.e., rigid certainty about the correctness of one's views). In an early study (involving men only), high dogmatism was associated with interests in military, business, and management-related occupations while low dogmatism was associated with interest in arts. Hansen was involved in updating the Strong Interest Inventory, originally developed by Edward Kellog Strong Jr., as an assessment of vocational interests. The Strong Interest Inventory has been widely used to identify people's preferred activities as a means of helping them to find suitable careers. Originally called the Strong Vocational Interest Blank, the inventory had separate forms for men and women. In 1974, Hansen was part of the team that published a new version (called the Strong-Campbell Interest Inventory) that combined the men's and women's inventories into a single form. With David P. Campbell and others, Hansen wrote the manual, user's guide, and applications and technical guide for the revised Strong Interest Inventory. Early in her career, Hansen aimed to relate John Holland's vocational model, which delineated six occupational themes (known as Holland codes), to women's responses on the Strong Interest Inventory. Notably, Hansen and her colleagues observed gender differences in the structure of interests using Holland's scheme, even when male and female participants were matched in occupational titles – suggesting that the theoretical model may need some adjustments to better account for women's behavior. Hansen's later work confirmed the stability of the observed gender differences in interests using data conducted over a span of decades. Hansen collaborated with Thomas J. Bouchard and others on research exploring the vocational interests of twins, including some who had been reared apart due to adoption. This study aimed to estimate genetic and environmental effects on responses to the Strong Interest Inventory. Representative Publications Hansen, J. I. C. (1987).
