This study assessed the extent to which students commit various types of errors when completing Holland's Self-Directed Search (SDS) entirely on their own. Nearly all students made some type of error and approximately half of the students made errors that affected their final 3-letter summary codes. Almost one-fifth of the students made errors…

Hexagonal configurations from the responses to the Vocational Preference Inventory by rural high school seniors were compared to Holland's model of occupational classification. (Author)

Findings suggest that a woman will obtain a different Holland code depending on what instrument or what set of scales within an instrument is used to establish that code. This phenomenon could reflect sample characteristics equally as much as any bias in the measures. (Author)

Results showed strong empirical support for the model in that most subjects were working in environments congruent with their personality types. However, there was a lack of empirical support for the proposed relatedness among the environments in the model with regard to person-environment congruence. (Author)

The use of a self-counseling device is explored as a diagnostic tool in identifying college students who may be better suited to vocational training programs. (Author)

The Realistic scale of the Vocational Preference Inventory (VPI) and the Realistic and Social scales of the Self Directed Search successfully differentiated the occupational groups. However, the VPI Social and Enterprising scales did not differentiate between men and women in the same occupation. (Author)

Discriminant analysis of Holland's Self Directed Search and Vocational Preference Inventory significantly improved the predictive validity of his classification scheme, over the traditional method of assigning high point codes. These results were obtained with both an initial and a replication sample of undergraduates pursuing various degrees. The…

A sample of male Investigative subjects (N=171) who completed the SDS as freshmen in 1970 was sent a questionnaire four years later. Results indicated that, for Investigative-type freshman males, the SDS has moderately high efficiency in predicting, four years later, their ultimate major and their immediate and future vocational plans. (Author)

Determines how the Self-Directed Search (SDS) achieves its effects. High school girls were assessed before and after treatment for vocational aspirations, knowledge of typology, and information seeking. Nonsignificant findings imply that SDS achieves its effects partly because of its numerous occupational options. Instructional booklets increase…

The number and type of errors in self administration and scoring made on Holland's Self-Directed Search (SDS) and Self-Directed Search Form Easy (SDS-E) were examined. Subjects were 96 learning disabled and 96 non learning disabled high school students. All subjects made more errors on the SDS than on the SDS-E. Differences are discussed.…

Examined the effects of the Self-Directed Search (SDS) in the light of the participants' personal characteristics, including their expectations for the treatment. Results reveal that the majority of students seek reassurance for choices they have made. A client's decision-making difficulties may be helpful in selecting an effective treatment.…

The appropriateness of raw score reports of human traits is questioned, especially in light of the support provided for Holland's theory by normed scores and the stereotypic career options suggested to males and females by raw scores. (Author)

The scales of the Self-Directed Search (SDS) were correlated with the scales of the Armed Forces Vocational Aptitude Battery (ASVAB) for a sample of 192 high school girls. The two devices have small to moderate correlations that indicate self-reported abilities and competencies have some concurrent validity. (Author)

Examined the performance of ninth-grade students on the Self-Directed Search during small group administrations monitored by a counselor. Results indicated scoring errors were high in comparison to norms. The percentage of erroneous summary codes was higher while transposition errors were lower, suggesting group administration with a proctor…

Prediger confuses observations about the data with Holland's theoretical statement, performs some uninterpretable analyses, omits much relevant data, and provides an incomplete account of what psychometric authorities have said about raw scores in interest inventories. (Author)
