The relation of congruence,differentiation, and consistency to interest and aptitude scores in women with stable and unstable vocational choices

This study examined by canonical variate analysis the relation between congruence, differentiation, and consistency, and academic aptitude and vocational interests for 280 women with stable vocational choices over 4 years and 327 women with unstable vocational choices over 4 years. Findings offered support for the importance of congruence in stable women; differentiation and consistency operated similarly for women with stable and unstable choices.     

Vocational identity and career choice congruence of gifted and talented high school students

This study examined the career development of gifted high school juniorss in terms of vocational identity and congruence. The My Vo;cational Situation (MVS)was used to measure the career development of gifted high school ljuniors. Gender differences in vocational identity were found. Students who hasd tentative career and college major choices were found to have a higher level of vocational identity than those who did not have tentative choices. Measures of career choice congruence and college major choice congruence were obtained by examining the agreement between the Holland interest code and the tentative career and college major choices of participants. Gender differences were found o;n college major choice congruence, but not on career choice congruence. Vocational identity was related to college major choice congruence, but not to career choice congruence. Implications for counselling gifted students and research were discussed.     

Traditionality of choice and sex-role identification as moderators of the congruence of occupational choice in college women

This study examined the relationship of traditionality of occupational preferences and sex-role orientation to personality-occupational environment congruence in college women. Three-letter Holland personality codes were obtained for each of 184 college women based on same-sex normative scores from the Strong-Campbell Interest Inventory and on scores from the ACT Unisex Interest Inventory (UNIACT). Subjects' occupational preferences were classified as traditional, moderately traditional, or nontraditional based on the percentages of women in the occupation. Scores on the Bern Sex Role Inventory were used to classify subjects into one of four sex-role categories. Results indicated a strong association between congruence and traditionality of choice; women whose choices were in nontraditional career fields were significantly more likely to be making choices congruent with their personality type than were women choosing traditional career fields. Further, while sex-role orientation was not significantly related to either congruence or traditionality, masculine-typed women were most likely to make nontraditional and congruent career choices, while the majority of feminine-typed, androgynous, and undifferentiated women stated preferences for traditional career fields. Implications for the applicability of Holland's congruence postulate to women's vocational behavior are discussed.     

Consistent curricular choice and congruence of subsequent changes

Curriculum choices of 324 male and 157 female liberal arts students who took the Strong-Campbell Interest Inventory (SCII) during freshman orientation were classified as congruent or incongruent on the basis of rated correspondence between three-letter codes derived from (SCII) Holland theme scales and expressed curricular choice. The choices of those subjects reporting one or more changes in five semesters were examined for level of congruence using a two-way analysis of variance with repeated measures. While serious methodological limitations are noted, analysis of variance procedures indicated that congruent subjects tended to be more stable, more differentiated, and more academically oriented than incongruent subjects. Among subjects who reported one or more changes, Artistic subjects decreased in congruence while Investigative subjects showed no overall change. Results are discussed in terms of recent theory and previous research.     

Stability and change in interests: A longitudinal study of adolescents from grades 8 through 12

The pattern of RIASEC interests and academic skills were assessed longitudinally from a large-scale national database at three time points: eight grade, 10th grade, and 12th grade. Validation and cross-validation samples of 1000 males and 1000 females in each set were used to test the pattern of these scores over time relative to mean changes, stability, crystallization, and interest-career choice congruence as well as how these patterns were moderated by gender. Results indicate that the pattern of interests was fairly stable in grades 8-12 for males and females. Interests were also found to become more crystallized over time; however interest-career choice congruence evidenced an inverted V pattern. With further examination, student interests became less people based and their career choices more people based in grade 12. The results support the importance of grade 12 as a time of focus for research and intervention, and for continuing investigation of gender differences in adolescent career and academic development.     

Relation of interest and self-efficacy occupational congruence and career choice certainty

A sample of 2145 adults completed the Personal Globe Inventory (PGI) as well as indicating their occupational choice and the certainty of this choice. The PGI yielded interest and self-efficacy scores and these were used with the occupational choice to calculate a congruence score for interests and one for efficacy. The prediction of career certainty by each congruence measure and their interaction was examined using hierarchical regression. The results indicated that while both interest and efficacy congruence were related to career certainty, efficacy congruence did not add to prediction above that obtained using interests congruence alone, however there was a substantial interaction. The agreement of interest congruence and efficacy congruence was related to a strong positive relation between congruence and certainty; whereas low agreement between interest and efficacy congruence was related to a non-significant relation between congruence and certainty. The results demonstrate the need to focus on both interest and efficacy and their agreement in our assessments and interventions.     

The Development of Person–Vocation Fit: A Longitudinal Study Among Young Employees

This two-phase panel study examines the development of the congruence between vocational interests and perceived skill requirements. Participants were 492 Dutch men and women between 18 and 26 years old, with a paid job in both phases. Three hypotheses inspired by the theory of work adjustment (Dawis and Lofquist 1984) and congruence theory (Holland 1992) were tested, using a composite index of fit proposed by Cronbach and Gleser (1953). The first hypothesis proposing that participants experiencing incongruence between their vocational interests and their perceived skill requirements are dissatisfied with their job was supported. The hypothesis that incongruence has a positive relationship with job change and a negative relationship with tenure was not confirmed. The expectation that the congruence between vocational interests and perceived skill requirements increases over time was confirmed. Furthermore, exploring determinants of change in vocational interests and perceived skill requirements, it was found that change in these domains was predicted by different variables, educational level being the only common factor. It is concluded that this study supports the longitudinal propositions of prevailing work-related person-environment fit theories.     

Occupational specialty congruence: New data and future directions

The present research examined the relationship between within-occupational congruence and satisfaction, and attempted to integrate hypotheses and findings of prior studies with the conceptual implications of occupational specialty congruence. Correspondence between vocational interests within occupations and specialty choice has shown higher correlations with satisfaction than with congruence (Assouline & Meir, 1987). Occupational specialty congruence was derived by comparing preferred functions with the actual functions characterizing a given occupational specialty. In the present study, involving 120 computer software professionals, occupational specialty congruence correlated approximately .45 with satisfaction, using core job function dimensions. Specialty change within occupation, rather than occupational change, may help in cases of poor occupational choice, burnout, or a change in health. Further research should explore the generalizability of the function dimensions employed herein. Identifying core dimensions can aid in designing both career tracks and certification exams.     

Occupational knowledge and career development in adolescence

In an effort to extend our knowledge of career development, two indices of career maturity were investigated in a sample of 6029 high school seniors sampled from 57 Texas public school districts. The study investigated both the degree to which late adolescents choose occupations whose educational requirements match their stated educational goals and the degree to which students' vocational interests are compatible with their occupational choices. The correlations between educational plans and educational requirements of the chosen occupations were .41 or less. Of the subjects who claimed to have at least considerable understanding of their first choice career, only about half planned to achieve the amount of education appropriate to enter that occupation. Subjects' perceptions of how well they understood their occupational choices were also negligibly related to the compatibility of their vocational interests and their career choices. Although educational understanding and interest compatibility both contribute to realism of occupational choices, the correlation between these two indices of career maturity accounted for less than 1% of the variance.     

Sex-role aspects in the development of children's vocational knowledge

Recent research suggests important age and sex differences in the sex-typing of children's vocational interests. The present study adds to this area by examining several dimensions of job choices in children of four age groups (early and late preschool, second and fourth grade). The 120 children interviewed were asked three fixed-choice questions regarding nine jobs, along with open-ended job choice items. Analysis of age effects on several predetermined dimensions showed that older children were more selective in personal job choice, especially in regard to jobs attributed to the opposite sex. Avoidance of choices associated with the other sex was stronger in boys, but other sex differences were dependent on mode of inquiry rather than on sex. Girls were less limited than boys in job interests when asked about specific jobs but expressed more restricted choices on open-ended items. Implications of these findings both for further research and educational practices are considered.     

Consistent occupational preferences and satisfaction,self concept,self acceptance and vocational maturity

This study explored the differences on variables of satisfaction, self-concept, self-acceptance, and vocational maturity between freshmen students who made congruent and incongruent occupational choices. The variables were operationally defined by the College Student Satisfaction Questionnaire, the Tennessee Self-Concept Scale, the Berger scales, and the Vocational Development Inventory. Congruent and incongruent current occupational choice groups were defined operationally using the Self Directed Search. The analysis of variance of the scale scores did not reveal the main effect of congruence to be significant. However, a second analysis using a more rigorous definition of congruence revealed the main effect of congruence to be significant for four satisfaction variables. Findings suggest that subjects in the congruent male group tend to report better maintenance of personal stability and greater satisfaction than subjects in the incongruent female group.     

Measured interests versus expressed interests as predictors of long-term occupational membership

This study compared the predictive accuracy of measured versus expressed interests over a 21-year period using as a criterion occupational membership at age 36. Subjects were 83 males whose measured and expressed interests were elicited at ages 15, 18, and 25. The Strong Vocational Interest Blank was used to determine measured interests while expressed interests were determined through a combination of questionnaires and interviews. C. McArthur's (Journal of Applied Psychology, 1954, 38, 346–353) method was employed to determine the predictive validity of subjects' measured interests. The predictive validity of expressed interests was determined by using A. Roe's (The psychology of occupations. New York: Wiley, 1956; Journal of Counseling Psychology, 1957, 4, 212–217) scheme for occupational classification to code occupational preferences and compare them to age 36 occupations. Results indicated that at each point in the study expressed interests were slightly better predictors of age 36 occupational membership than measured interests. Supplementary analyses revealed no relationship between the extent to which subjects' measured or expressed interests corresponded to age 36 occupations and either overall job or career satisfaction.     

Investigative versus realistic Holland types and adjustment in theoretical engineering majors

This study tested the sensitivity of J. L. Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) congruence method for predicting differential outcomes in the case of subtle person-environment congruence differences. This question is relevant to engineering programs, where students with adjacent Holland orientations of Investigative (I) and Realistic (R) aspire to complete theoretically oriented engineering majors, such as electrical and mechanical engineering. It was hypothesized that high congruence (e.g., I-type student in I-type engineering major) compared to moderately high congruence (e.g., R-type in I-type major) would result in more positive educational outcomes. A preliminary analysis verified that subgroups of I- and R-type students possessed similar scores on measures of general and math aptitude. Results on both outcome measures favored the high student-curriculum congruence hypothesis. I- compared to R-type subjects demonstrated greater persistence in their initial engineering major over a 2-year period and attained higher grades. Persistence findings replicated across two separate classes of entering students, but academic performance differences were not as consistent.     

The role of friends in career compromise: Same-gender friendship intensifies gender differences in educational choice

We propose a mechanism of how the desire to maintain friendships can intensify gender differences in educational choice. The required conditions for this mechanism would be that (1) adolescent males and females differ in their overall educational preferences, (2) wanting to stay close to friends motivates some adolescents to adjust their educational choice in line with their friends' choices, and (3) adolescents have a higher share of same-gender, than other-gender, friends. Study 1 confirmed that these criteria were met, and Study 2 found an association between friendship priority and gender typed field of study. In conclusion, adjusting educational choices in order to maintain friendships put adolescents at risk of compromising their true career interests, and also becomes an obstacle to a gender balanced labor market.     

Exponential decay of spatial memory of rats in a radial maze

The persistence of spatial memory of rats (n = 14) was investigated in an eight-arm radial maze. The animals were trained until the mean number of errors in the first eight choices was 0.2. The decay of performance with time was studied using delays of 5, 20, 60, 120, or 240 min between choices 4 and 5, during which the animal was removed from the apparatus. A delay of 60 min significantly impaired performance. The mean number of errors was not significantly different from the random choice level after a delay of 120 min. The increase in the number of errors with time was exponential. Comparison of the results with those of previous studies suggests that the nature of training may have effects on memory persistence in the radial maze.     

Congruency,consistency, and differentiation as predictors of job satisfaction within the nursing occupation

Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) congruency, consistency, and differentiation terms were used as independent variables to predict job satisfaction (JS) within the scope of a single occupation, rather than on the comparison between occupations. Based on the responses of 126 registered nurses on the specially designed List of Courses in Nursing (LCN) Inventory the congruence hypothesis was confirmed, while the consistency and differentiation hypotheses were only partially supported. The hypothesis on the additive relationship among congruence, consistency, and differentiation with JS was confirmed. The theoretical and practical implications are discussed.     

Expressed and inventoried vocational interests as predictors of college graduation and vocational choice

This is a follow-up study of 195 agricultural students originally tested when they entered college in 1970. Students whose Strong Vocational Interest Blank (SVIB) patterns were consistent with their stated choice of major were the congruent sample. Students whose SVIB patterns were inconsistent with their stated choices of major were the discrepant sample. A follow-up was made on graduation rates, eventual major, and job placement. Discrepant subjects changed major more often but graduated at the same rate as congruents. The SVIB did not seem to add anything to the student's expressed interests in predicting college continuation. There was a trend for congruent graduates to more frequently take jobs which matched their majors.     

The Predictive Value of a Student's Choice of Vocation

Using large samples of college students, this study compares the forecasting value of a student's initial report of his vocational choice with the Vocational Preference Inventory. Student vocational choices were categorized according to a 6-category classification scheme for men and an 8-category scheme for women. The relationships between initial and final vocational choices, and between VPI high-point codes and final vocational choices over 8- and 12-month intervals, were examined. The results indicate that the predictive efficiency of a student's expressed choice is about twice that of the Vocational Preference Inventory. The results suggest that researchers and counselors should make greater use of a person's expressed choices and that interest inventories should be used with more discrimination. Implications for future research and practice are discussed.     

Holland's personality constructs as predictors of stability of choice

It was the purpose of this study to test Holland's assertion that stability of vocational choice can be predicted from: (a) congruence of personality with chosen career, (b) differentiation of personality, and (c) internal consistency of personality characteristics. The relationship of each of the three constructs to stability of choice of college major was studied among 167 university students. It was hypothesized that prediction could be improved by combining congruence, differentiation, and consistency in a multiple relationship. The relative importance of the three constructs was examined. Findings supported Holland's contention that congruence and consistency are positively related to stability. No significant relationship was found between differentiation and stability. When combined, all three constructs predict stability, but the efficiency of prediction is not improved by adding differentiation and/or consistency to congruence. As hypothesized, congruence was found to be the most important predictor, followed in importance by differentiation and consistency, respectively.     

The predictive validity of Holland's construct of consistency

Holland's construct of consistency was studied for its predictive validity of certain measures of vocational stability. A new measure of consistency used was the difference between two plotted vocational choices on the American College Testing Program's Map of College Majors which 1248 subjects expressed while in high school. This consistency index was found to have no relationship with the similarity of the same subjects' beginning and ending college majors, also measured as a distance on the Map of College Majors. Additionally, no relationship was found to exist between the consistency index and number of college major changes, the number of course withdrawals, academic performance, and scholastic aptitude.
