A sample of 358 men and 360 women took the Self-Directed Search, a vocational guidance tool developed by HoEand based on his theory of vocational choice. Data from the sample were subjected to factor and configural analysis in an attempt to verify the relationships among Holland's personality types, to clarify the characteristics of each type, and to extend Holland's hexagonal model to new domains of assessment. The results of the analyses offer empirical support for the hexagonal arrangement of the personality types and also support the organization of the Self-Directed Search and Holland's Occupational Classification.
