This study was designed to identify the important clusters of occupational groups identifiable from an analysis of the dimensions accounting for similarity in profile shapes among a set of 28 new vocational interest measures. (Author)

The 22 basic interest categories on the Strong Vocational Interest Blank for Men were used to classify the interests of men in 62 occupations. At least nine categories were required to describe adequately the interests of most occupational groups. (Author)

This study investigated differences between men and women employed in traditional male occupations using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS). Results indicate men in traditionally male occupations, when compared to women in those same occupations, tend not to report higher mean raw scale scores. (Author)

The authors investigated the concurrent validity of Holland's theory for employed non-college-degreed men using two inventories of vocational orientation. The results revealed that two scales of one and four scales of the other inventory successfully differentiated the occupational groups consistant with Holland's theoretical framework. (Author/SE)

The study was designed to explore the concurrent validity of Holland's theory for employed non-college degree black men. Concurrent validity was studied by administering the Vocational Preference Inventory (VPI) and the Self Directed Search (SDS) to workers. Results tend to suggest that Holland's theory is meaningful for employed non-college…

This study investigated differences in vocational attitude maturity and self-concept among Holland's six vocational categories. There were significant differences in vocational attitude maturity and self-concept among students in the six vocational categories. There was a significant relationship between vocational attitude maturity and…

It was hypothesized that first borns would prefer person- and intellectually-oriented occupations. It was also predicted that women, more than men, would prefer person-oriented occupations. The Hebrew version of Roe's classification of occupations was completed by 146 individuals. Only the second hypothesis was confirmed. (Author/SE)

Hypotheses tested were concerned with the psychological orderliness of occupational changes, the relationship between occupational experiences and aspirations, and the relationship between consistent occupational codes and the stability of work histories. The analyses supported the usefulness of the occupational classification for organizing the…

The semantic differential was used to assess the properties of affect elicited by occupational stimuli. Vocationally committed men studying medicine, business, and engineering responded to a semantic differential containing occupational concepts. Results show a semantic space for all three groups composed of three orthogonal dimensions of affect…

A test of Holland's vocational theory across and within selected occupational groups demonstrated concurrent validity for three of the four groups investigated. Statistically significant coefficients of concordance indicated a degree of agreement among individuals in each of the occupational groups investigated. (Author)

Differences in vocational interests, as measured by the Strong-Campbell Interest Inventory, between undergraduates having traditional, conservative attitudes towards the roles of women and those having contemporary, liberal attitudes were examined. Results are discussed and implications for future employment patterns are made. (Author)

A basic assumption underlying Holland's theory of careers is that men and women in the same occupation have the same personality pattern. Contrary to expectations, this research shows there are substantial and systematic differences in the Holland raw codes of males and females pursuing the same occupations, especially nontraditional occupations.…

A Q-factor analytic technique applied to the Strong Vocational Interest Blank (SVIB) basic interest scales of 156 males yielded three bipolar factors described as conceptual, interpersonal, and volitional. The degree of fit between interests and job categorization related significantly to ratings of job satisfaction. (Author)

The generalizability of Holland's characterizations of adults within the occupational categories was investigated in a group of 402 Mexican-Americans. The personality characteristics of the male groups provide strong support for the generalizability of Holland's characterizations to Mexican-American males. (Author)

The distribution of major choices of the students in college living units, as determined by the Holland (1973) typology, was related to the characteristics of the social environments of the living units. The results supported Holland's theory in that these two sets of variables were predictably related. (Author)
