The Construction,Preliminary Validation,and Correlates of a Dream‐Specific Scale for Mystical Experience

This study aimed to create and test a dream‐specific version of Hood's Mysticism (M) Scale for the purpose of studying dreaming mystical experience. Factor analysis of the Spiritual Dreams Scale (SDS), based on data collected from 289 adults affiliated with an American evangelical Christian school, clearly resulted in three factors in accordance with prior studies of the M Scale. However, the factor composition of the SDS did not identically resemble the findings of previous studies of the M Scale. Instead, the three‐factor solution suggested a Jamesian interpretation according to which the factors were labeled mystical psychology (passivity), perceived alternate reality (ineffability), and noesis. Scores on the SDS shared significant positive correlations with scores for absorption, dream beliefs, dream recall, and kataphatic prayer. A scale for apophatic prayer failed to share a significant correlation with the SDS.     

The moderating effect of private self-consciousness on the stability of vocational interests

This study investigated the potential moderating effect of private self-consciousness on the stability of vocational interest inventory scores and profiles. We hypothesized that participants higher in private self-consciousness would have more stable interest scores and profiles on the Self-Directed Search (SDS; Holland, Fritzsche, & Powell, 1994) across a 12-week time interval than would participants lower in private self-consciousness. Results revealed that private self-consciousness did moderate the stability of SDS Enterprising interest scores. Contrary to our hypothesis, private self-consciousness did not moderate the stability of the other five SDS interest scores or SDS interest profile stability.     

Psychometric properties of the Chinese Self-Directed Search (1994 edition)

In this study, we (a) examined the measurement equivalence/invariance (ME/I) of the Chinese Self-Directed Search (SDS; 1994 edition) across gender and geographic regions (Mainland China vs. Hong Kong); (b) assessed the construct validity of the Chinese SDS using [Widaman, 1985] and [Widaman, 1992] MTMM framework; and (c) determined whether vocational interests are measured equivalently by Chinese SDS subtests. Confirmatory factor analyses suggested that males and females from Mainland China and Hong Kong interpreted the instrument in conceptually similar manner. Also, the Chinese SDS demonstrated sound construct validity. However, we found that like-named interests were not measured equivalently by the SDS subtests.     

Concurrent validity of Holland's theory for non-college-degreed working women

This study, using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS), explored the concurrent validity of Holland's theory for employed non-college-degreed women. The VPI and SDS were administered to 114 women workers in occupational environments consistent with Holland's vocational environments. The results revealed that three scales of the VPI and five scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed non-college-degreed women.     

Simultaneous and staggered dichotic word and digit tests with stutterers and nonstutterers

The present study compared the performance of stuttering adults and matched controls on the Staggered Spondaic Word (SSW) test and three experimental digit tests—Two Pair Digit—TPD, Staggered Digits Simultaneous—SDS, and Staggered Digits Offset—SDO. Results indicated differences between stuttering and nonstuttering group mean values on the left ear scores of the TPD test, and on the numbers of reversals on both the SDS and SDO tests. The SSW, SDS, and SDO tests were all found to produce similar results in both stutteres and nonstutterers. However, the numbers of reversals on the SDS and SDO tests were significantly greater than those observed on the SSW test for both groups. Finally, the TPD test was found to be significantly more difficult for both groups than either of the other two experimental tests (i.e., SDS and SDO). These results are discussed in terms of similarity and differences with other dichotic listening studies. Limitations of the study and implications for further research are also presented.     

Concurrent validity of Holland's theory for college-degreed black women

This study, using the Vocational Preference Inventory (VPI) and the Self Directed Search (SDS), explored the concurrent validity of Holland's theory for employed college-degreed black women. The VPI and SDS were administered to 93 black women workers in occupational environments consistent with Holland's six vocational environments. The results revealed that four scales of the VPI and five scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed college-degreed black women.     

Sexual dimorphism in stature (SDS), jealousy and mate retention

Previous research has investigated the manner in which absolute height impacts on jealousy and mate retention. Although relative height is also important, little information exists about the potential influence of sexual dimorphism in stature (SDS) within established relationships. The current study investigated the relationship between SDS and the satisfaction, jealousy and mate retention behaviors reported by men and women. Heterosexual men (n = 98) and women (n = 102) completed a questionnaire. Men in high SDS relationships reported the lowest levels of cognitive and behavioral jealousy, although the impact of SDS on relationship satisfaction was less clear. SDS was not associated with the overall use of mate retention strategies; SDS did however affect the use of three specific strategies (vigilance, monopolization of time, love and care). SDS did not affect women's relationship satisfaction, jealousy (cognitive, behavioral, or emotional) or the use of mate retention strategies (with the exception of resource display).     

Concurrent validity of Holland's theory for non-college-degreed black women

This study, using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS), explored the concurrent validity of Holland's theory for employed non-college-degreed black women. The VPI and the SDS were administered to 102 black women workers in occupational environments consistent with Holland's six vocational environments. The results revealed that four scales of the VPI and four scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed non-college-degreed black women.     

Neutralizing sexist titles in Holland's Self-Directed Search: What difference does it make?

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 from the items and test-taking instructions, as well as the affixing of the letters M/F and F/M to all occupational titles and terms commonly perceived as gender specific. Subjects were 266 lower division female students at a large state university; 133 subjects completed the standard SDS and 133 completed the revised form. Following SDS assessment, subjects rated their inventory with respect to perceived sexual equality. Comparison variables included: daydreams, occupations' scores, summary codes, and subsequent occupational choices. Occupational choices at each stage of the assessment process were classified as nontraditional or traditional choices for women. Results indicated that across all indices derived from the standard and revised versions of the SDS, there were no significant differences in these subjects' performance. The subjects did perceive the two inventories differently, with subjects completing the standard SDS viewing it as slightly less equitable.     

The predictive efficiency of Holland's SDS summary codes in terms of career choice: A four-year follow-up

This study was designed to investigate the predictive efficiency of the primary and secondary summary codes of Holland's Self-Directed Search for Educational and Vocational Planning (SDS) in terms of expressed career choice 4 years later. In 1974, 126 voiationally undecided high school seniors were given the SDS, followed by a revision of Trow's Vocational Choice Inventory (VCI) in which they were asked to express a career choice or a state of indecision. In 1978, this same group was mailed a posttest VCI; the responses of 84 subjects were then analyzed. The subjects' expressed career choices on both the 1974 and 1978 VCI were compared to the primary and secondary summary codes on the SDS which they had taken in 1974. Inspection of the responses indicated that 21.4% of the subjects had made career choices predicted by their primary summary codes and 51.2% had made vocational choices found among their secondary summary codes. Only 27.4% chose a career area not predicted by their 1974 SDS results. The results of this study appear to lend support to the validity of using the SDS summary codes to predict eventual career decisions.     

The predictive power of Holland's investigative personality type and consistency levels using the self directed search

Using the Self Directed Search (SDS), the predictability of Holland's Investigative personality type and the three levels of consistency were assessed. A sample of male Investigative subjects (N = 171) who completed the SDS as freshmen in 1970 was sent a questionnaire 4 years later. The questionnaire asked subjects to state their academic major, occupational plan upon graduation, and occupational plan 5 years hence. Hypotheses concerned the predictability over a 4-year college period of (1) one-, two-, and three-letter SDS and most recent daydream codes and (2) Holland's three levels of consistency. Results indicated that, for Investigative-type freshman males, the SDS has moderately high efficiency in predicting, 4 years later, their ultimate major and their immediate and future vocational plans. The differential predictability of Holland's three consistency levels was supported in 20 of the 27 tests applied.     

Holland's theory and non-college-degreed working black and white women

The main concern of this study was to investigate differences between black and white American women employed in traditional female occupations who took the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS). The VPI and the SDS were administered to 110 black and white non-college-degreed workers in three occupations (laboratory technicians, sales clerks, and clerk-typists) corresponding to three of Holland's environmental categories (Investigative, Enterprising, and Conventional). In general, the findings for the three VPI and SDS scales and for these six occupational groups are mixed. On the SDS scales, findings indicate that black and white women in the same occupation seem to be far more similar than different. On the scales of the VPI, however, white and black women in the same occupation seem to be more different than similar.     

Holland's SDS: Is its effectiveness contingent upon selected variables?

This study was designed to investigate the differential effectiveness of Holland's Self Directed Search (SDS) as a vocational guidance tool for 166 junior-class students in a suburban regional high school. The SDS was administered to 90 girls and 76 boys who were subsequently interviewed and asked to state current first and second vocational choices. The relation between these choices and the students' three-letter SDS codes was translated into numerical Congruence Scores. Students were also grouped according to: (1) their SDS codes' level of consistency with Holland's hexagonal model; (2) differentiation of codes; (3) level of mental ability; and (4) level of achievement. Four two-way analyses of variance were used to assess the effect of these variables on Congruence Scores; in each analysis, sex was the second classification in order to measure interaction-effects. Results indicated no significant mean differences on Congruence Scores attributable to these variables. The effectiveness of the SDS as a career inventory does not appear to be contingent upon them.     

The Zung Self-Rating Depression Scale: convergent validity and diagnostic discrimination

This study examined the concurrent validity of the Zung Self-Rating Depression Scale (SDS) in relation to the Depression (D) scale of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and addressed a gap in the literature with respect to diagnostic discrimination. The participants were persons on probation or parole. Although women were more depressed than men on the SDS, gender did not interact with SDS as a predictor in a logistic regression analysis. The SDS was found to be the primary discriminating variable in distinguishing depressed from nondepressed participants. In addition, the SDS contributed significant incremental validity over the D scale and showed greater accuracy in identifying nondepressed individuals.     

Holland's theory and college-degreed working black and white women

The main concern of this study was to investigate differences between black and white women employed in traditional male occupations who took the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS). The VPI and the SDS were administered to 155 black and white college-degreed workers in three occupations (engineering, medicine, and law) corresponding to three of Holland's environmental categories (Realistic Investigative, and Enterprising). In general, the findings for the three VPI and SDS scales for these occupational groups indicate that white women when compared to black women in the same occupation tend to report similar mean raw scores.     

A theory of careers encounters sex: Reply to Holland (1976)

This paper is the third in a series beginning with a report (by the authors) of research on the application of Holland's theory of careers to women and men. Holland's response, “The Virtues of the SDS …” is considered, in particular, research he cites on the effect of the Self-Directed Search (SDS) on counselees and his advocacy of raw score reports of personality patterns. The widely divergent career options suggested to men and women by SDS raw scores are noted and misunderstandings concerning the implications of Holland's assessment procedures for his theory are discussed. Holland's defense of raw score reports of personality characteristics is found wanting, especially in light of the support provided for his theory by normed scores.     

Holland's theory and college educated working black men and women

The main concern of this study was to investigate differences between college educated working men and women employed in traditional occupations who took the Vocational Preference Inventory (VPI) and the Self Directed Search (SDS). The VPI and the SDS were administered to 109 black college educated workers in three of Holland's environmental categories (Realistic, Investigative, and Enterprising). In general, the findings for the three VPI and SDS scales and for these occupational groups indicate that black women when compared to black men in the same occupation tend to report similar mean raw scores. Black men and women in the same occupation seem to be far more similar than different.     

Concurrent validity of Holland's theory for college degreed working women

The study was designed to explore two areas: (1) the concurrent validity of Holland's theory for employed college degreed women using two different operational definitions (Vocational Preference Inventory and the Self-Directed Search) of vocational orientation; and (2) the relationships among same named scales across the VPI and the SDS. Concurrent validity was studied by administering the VPI and the SDS to 179 women workers in occupational environments consistent with Holland's six vocational environments. In general, the findings indicate that the VPI and SDS scales tend to effectively discriminate among the occupational groups consistent with Holland's theoretical framework. In addition, the correlation coefficients for same named scales for the two inventories were all found to be significant. In sum, the results of the study lend some support to the concurrent validity of Holland's theory for employed college degreed women.     

Vocational maturity and anxiety among vocationally undecided and indecisive students : The effectiveness of Holland's Self-Directed Search

This study was designed with two purposes in mind: (1) to measure the effectiveness of Holland's Self-Directed Search for Educational and Vocational Planning (SDS); and (2) to test the validity of Goodstein's (Theories of Counseling. B. Stefflure, Ed., 1965) hypothesis that career indecision and indecisiveness are differentially related to anxiety and vocational maturity. A total of 66 high school males and 60 high school females were randomly assigned to experimental and control groups and tested for anxiety and vocational maturity levels; the experimental subjects were given the SDS. Statistical analysis indicated that the SDS was an effective instrument in reducing career indecision; Goodstein's hypothesis was not supported by the results of the study.     

A Criterion-Related Validity Study of the OASIS-2 Interest Schedule

A total of 36 rising high school seniors who were participating in a summer program designed to encourage interest in attending college were administered the Self-Directed Search (SDS) and OASIS-2 Interest Schedule. Correlational analyses identified statistically significant relationships between SDS and OASIS-2 scales. In most cases, scales one would expect to find related to one another correlated significantly and at a level many would consider to be acceptable for establishing criterion-related validity. Implications of the results for those practitioners using the OASIS-2 Interest Schedule are discussed.
