Vocational interest structures for Asian Americans, Middle-Eastern Americans and Native Americans on the 2005 Strong Interest Inventory

• A RIASEC ordering of interests was found in Asian, Middle-Eastern, and Native American samples on the 2005 SII.
• A good fit was found for both a circular and an equidistant model regardless of gender and student/occupational status
• More variance was accounted in a less-stringent circular RIASEC model for all samples.

This study examined whether the vocational interests of Asian Americans, Middle-Eastern Americans, and Native Americans, as measured by the 2005 Strong Interest Inventory (SII), followed Holland's (1997) calculus hypotheses for a RIASEC ordering. The structures of interests of these three racial/ethnic groups were examined for fit with two structural models: (1) a less-stringent model requiring a circular RIASEC ordering and (2) a more stringent model requiring equal distances between adjacent interest types. Individuals who completed the 2005 Strong Interest Inventory were included in the sample (N = 22,394), and the overall sample was divided between racial/ethnic groups, gender, and professional status (i.e. student and employed adults). Results from randomization tests of hypothesized order and circular unidimensional scaling analyses found that a circular RIASEC order is applicable to Asian American, Middle-Eastern American and Native American students and employed adults, regardless of gender, when measured by the 2005 Strong Interest Inventory. Results from this study indicate that the current version of the Strong Interest Inventory measures vocational interests in a manner that strongly aligns with Holland's calculus hypothesis for both men and women.
