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)

Six in-general samples have been generated to fit different developments of the SVIB, Twenty experimental homogeneous scales were used to measure the similarities and differences among the six in-general samples. Generally, all samples were strikingly similar with the greatest differences appearing between male and female in-general samples.…

Three age groups in six occupational samples were tested on the SCII and their scale scores were examined for significant differences. Data indicates that interests generally are not different for people of different ages in the same occupation. (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)

Results of assigning Holland codes to items seems reasonable, and the codes may be used in future item pool revisions to balance item content, to eliminate poorly defined items, and to select items that are perceived identically by females and males. (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)

Reliability and concurrent validity data for the (SCII) were developed for a sample of 180 students. Two-week test-retest reliability correlations were approximately .90. Agreement between high scores and self-reported curriculum and occupational preferences ranged from 32 percent to 60 percent. Scoring on all Occupational scales produces…

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)

Research was conducted to develop an interest inventory corresponding to the interest areas in Volume II of the fourth edition of the Dictionary of Occupational Titles. An inventory of 307 occupational activity items was developed and administered to a sample of 1,115 individuals in a selected number of states. (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 sample groups consisted of 570 women and 1,031 men who were National Merit Scholars in 1966. Differentiations of career groups from the SVIB-M were compared for men and women. Results suggest that a single form of the Strong Vocational Interest Blank is potentially feasible for predicting college major and career choices of women as well as…

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…

An investigation of the relationships and underlying constructs between expressed and inventoried interests across the occupational classification scheme of Holland, Roe and Strong was undertaken. The canonical factor structures that were calculated indicated two similar bipolar structures underlying the occupational schema studied. (Author)

Data on the reliability and validity of the sex-valances scales are summarized along with data from previous research on sex-balanced scales and reporting procedures. Data include that sex differences currently found in interest inventory scores may simply be an unfortunate legacy from an era that took traditional sex roles for granted. (Author)
