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)

The Ramak and Courses interest inventories based on Roe's (1956) occupational classification were modified for use with subjects who answer negatively to most items in the traditional forms. Negative respondents give more positive responses on the modified forms than on the traditional ones. (Author)

This study was designed to test and expand Holland's vocational development theory by utilizing more than a single high point code in classification of personality patterns of jobs. A more "refined" and/or "subtle" difference was shown in the personality-job relationships when two high point codes were used. (Author)

The Vocational Preference Inventory responses from 290 subjects were subjected to a Rasch item analysis, one of a class of latent trait models. After elimination of 22 items which did not fit the model, a sex-free form of the VPI was obtained. (Author)

The relationships between the six scales on which Holland's theory is based and the five other scales of the Vocational Preference Inventory were investigated using canonical analysis. (Author)

Modification of instructions to the Activities and Competencies section of Holland's Self-Directed Search to allow users more flexibility in responding to items was compared to the standard set of instructions. Results indicated modified instructions did significantly alter users' summary codes although users were not more satisfied. (Author)

The Vocational Rating Scale (VRS) is a 40-item self-rating scale which attempts to directly assess the individual's awareness of the degree and nature of patterns in his or her specific vocational self-concepts. Scores on the VRS are related to the degree of certainty regarding overall self perception. (Author)

Recent concern for eliminating Strong Vocational Interest Blank (SVIB) sex bias has focused on the current use of separately normed Occupational Scales for the two sexes. This study implemented six basic methods of scale construction to examine the feasibility of combined-sex scales. (Author)

Analyses of interscale relations in 235 college students for the Vocational Preference Inventory and Vocational Interest Inventory, based on interest models of Holland and Roe, respectively, suggest that the two-dimensional, circular configuration of occupational or personality types may be an oversimplification which impedes the understanding of…

The purpose of this study was to investigate the construct validity of the occupational themes on the Strong Campbell Interest Inventory. Male (n=199) and female (n=204) college counseling center clients were administered the SCII and the Edwards Personal Preference Schedule (EPPS). The occupational themes and related descriptors were validated in…

In the present study, the Vocational Preference Inventory scores for a group of black students and white students were factor analyzed and the black structure was rotated to correspond to the white structure. The correspondence between the variables for black and white students was found to be very similar. (Author)

Sex-role stereotyping in the linguistic structure of Holland's Self-Directed Search (SDS) was examined. A revised SDS was constructed involving the removal of all masculine-toned terminology. The subjects did perceive the two inventories differently, with subjects completing the standard SDS viewing it as slightly less equitable. (Author)

This investigation represents an attempt to develop and validate a research instrument (Manifest Needs Questionnaire) capable of measuring the four needs of achievement, affiliation, autonomy, and dominance using behaviorally-based scales. The instrument is designed to measure such needs with specific reference to work settings. (Author)
