Structure of vocational interests in Serbia: Evaluation of the spherical model

To explore the structure of vocational interests in Serbia, 1063 participants of various age, education and gender completed the Serbian version of the Personal Globe Inventory [PGI, Tracey, T. (2002). Personal Globe Inventory: Measurement of the spherical model of interests and competence beliefs. Journal of Vocational Behavior, 6, 113-172]. The fit of Tracey’s octagonal and spherical models to the structure of correlations between Tracey’s eight and 18 type scales was evaluated, as was the fit of Holland’s hexagonal, Gati’s, Rounds-Tracey’s and Liu-Rounds’ models to the structure of correlations between RIASEC scales. Randomization test of hypothetical orders, multidimensional scaling with fixed coordinates and Myors’ test were used to assess the fit of models to the data. The results showed good fit of Tracey’s octagonal and spherical models to the data. Holland’s hexagonal model also fit the data very well, but the fit of Gati’s, Rounds-Tracey’s and Liu-Rounds’ models of relations between RIASEC types was either nonsignificant or very low.     

The structure of vocational interests in Germany: Different methodologies, different conclusions

The cross-cultural generalizability of vocational interest structures has received significant attention in recent years. This article adds to this research in four respects. First, data from a context that has not previously been investigated (Germany) was analyzed. Second, students at different stages of their educational career were examined. Third, the interest structure in male and females was compared. Fourth, two methods—the randomization test of hypothesized order relations (RTOR) and confirmatory factor analysis (CFA)—were applied to three competing structural conceptions: Holland’s circular representation, Gati’s hierarchical model, and Rounds and Tracey’s alternative hierarchical model. RTOR supported all three representations, whereas CFA supported only Holland’s model. CFAs indicated that the interest structure is reasonably invariant between high school and university students, but that the configurations for high school females and males differ. Substantive and methodological implications are discussed.     

Examination of the structure of Irish students’ vocational interests and competence perceptions

A sample of 307 Irish high school students completed a modified version of the Personal Globe Inventory (PGI, Tracey, 2002). Results of separate principal components analyses demonstrated the presence of three substantive factors: People/Things, Data/Ideas, and Prestige, similar to the structure of the PGI in US samples (Tracey, 2002). The fit of Holland’s six-type RIASEC, the PGI eight-type model, and the PGI spherical structure to the data were examined using the randomized test of hypothesized order relations. The results demonstrated that each model fit the Irish data well. No structural differences were found between gender groups. The results support the structural validity of the modified PGI in an Irish context.     

Personality facets and RIASEC interests: An integrated model

Research examining links between personality and interest have typically focused on links between measures of the five factor model and Holland’s RIASEC types. However, the five factor model of personality can be divided in to a larger set of narrow domain personality scales measuring facets of the ‘big five’ traits. Research in a number of fields indicates that facet scales are effective for clarifying the relationship between personality and other broad constructs, including academic achievement, job performance, stress and coping, and achievement motivation. In the present study links between personality facets and the RIASEC model were examined using property vector fitting. Obtained results are consistent with previous research suggesting that the use of facet-level personality measures can clarify relations between personality and other constructs, and provides new information linking personality facets and interests. The use of facet-level measures of personality expands the range of personality concepts that can be presented to individuals who are exploring career options.     

Winning at work: Trait competitiveness,personality types,and occupational interests

This study examined the relationship between trait competitiveness and occupational interests of under-graduates prior to entering the work force. The findings indicate that competitiveness is related to Investigative and Realistic types within Holland’s model of vocational choice and that competitive individuals are attracted to jobs involving competition and competitive pressure based on O*NET job characteristic ratings. Implications for future research are discussed.     

Vocational interests across 20 years of adulthood: Stability,change, and the role of work experiences

Vocational interests demonstrate high rank-order stability during childhood and adolescence. However, few studies have investigated the development of vocational interests into adulthood. The present study examined rank-order and profile stability, mean-level and correlated change, and individual differences in change in RIASEC scores across 20 years of adulthood. In addition, life events were examined as moderators of change. Rank-order stability was strong across vocational interest dimensions. Mean-level changes also occurred, with increases in Realistic interests and decreases in Investigative interests for men, increases in Enterprising interests for women, and decreases in Artistic interests for men and women. Individual differences in change indicated that not everyone changed in the same manner, with occupational experiences, such as job loss, related to greater change.     

Getting interested in interests for employee selection: Key concerns and areas for future research

The paper by Wille and De Fruyt suggests that vocational interests should be used throughout the human resources cycle and provides a useful model that can facilitate the application of interests throughout this process. This commentary builds on their review to discuss the unique benefits and challenges of implementing vocational interests in the employee selection process. Using research from the employee selection literature, we also discuss potential solutions for many of the issues raised by Wille and De Fruyt. Therefore, our commentary is meant to supplement the focal article and answer specific questions about why and how vocational interests can be used in this high-stakes setting.     

Re-conceptualizing the past: Historical data in vocational interest research

Noteworthy progress has been made in the development of statistical models for evaluating the structure of vocational interests over the past three decades. It is proposed that historically significant interest datasets, when combined with modern structural methods of data analysis, provide an opportunity to re-examine the underlying assumptions of J.L. Holland’s [Holland, J. L. (1959). A theory of vocational choice. Journal of Counseling Psychology, 6, 35–45; Holland, J. L. (1997). Making vocational choices (3rd ed.). Odessa, FL: Psychological Assessment Resources] RIASEC model. To illustrate this potential, data obtained from J. P. Guilford’s study of interest structure were re-analyzed using modern circumplex and hierarchical clustering techniques to evaluate Holland’s and I. Gati’s [Gati, I. (1979). A hierarchical model for the structure of interests. Journal of Vocational Behavior, 15, 90–106; Gati, I. (1991). The structure of vocational interests. Psychological Bulletin, 109, 309–324] interest structures. Obtained results indicate that a circumplex model can be used to effectively represent the structure underlying Guilford’s interest measures. However, hierarchical clustering results suggest that Holland’s RIASEC types may not be the most effective categories for grouping specific interest measures into broader interest areas. The current findings provide support for the continued investigation of alternatives to Holland’s interest categories using modern measures of basic interests.     

The structure of vocational interests in Filipino adolescents

The structure of vocational interests was investigated in Filipino high school students (N = 503), who rated their interest in 303 culture-relevant occupational titles and 93 major fields of study. Item-level principal components analyses identified general interest, prestige, and sex-type dimensions, rather than Prediger's (1982) People/Things and Data/Ideas dimensions. Additional factor analyses were conducted to derive scales that measure more specific interests, including Unskilled/Semiskilled Labor, Male-dominated, Engineering/Technology, Science, Medical, Arts, Commerce, Government/Law, and Education. The interest scales showed some resemblance or overlap with Holland's types, and gender differences on the scales conformed to expectations. However, the relationships among the scales and occupations were better accounted for by prestige and sex-type than by People/Things and Data/Ideas dimensions or by Holland's circular model. Developmental, cultural, educational, and economic factors that might account for Filipino students' focus on prestige and sex-type were discussed.     

The fit of Holland’s RIASEC model to US occupations

Holland’s [Holland, J. L. (1959). A theory of occupational choice. Journal of Counseling Psychology, 6, 35-45; Holland, J. L. (1997). Making vocational choices: A theory of vocational personalities and work environments (3rd ed.). Odessa, FL: Psychological Assessment Resources, Inc.] RIASEC types were initially developed using a restricted range of occupational titles. Holland’s type classification system has been extended to encompass the full range of occupations in the US, using both statistical and expert rating methods. However, the extent that Holland’s classification model is sufficient to represent the full range of occupational interests has not been examined. Multidimensional scaling (MDS) was used to analyze college students’ (266 men, 572 women) interests in occupations representing approximately 85% of the US labor market. A two-dimensional MDS solution of the full set of occupations did not fit Holland’s model, but limiting the analysis to occupations used in Holland-based measures produced the expected RIASEC structure. In comparison, a three-dimensional solution included Prediger’s [Prediger, D. J. (1982). Dimensions underlying Holland’s hexagon: Missing link between interests and occupations? Journal of Vocational Behavior, 21, 259-287] dimensions (Things/People and Data/Ideas) consistent with Holland’s model, but also included prestige and sex-type dimensions that were not orthogonal to Prediger’s dimensions. These results demonstrate that the RIASEC types are not sufficient to represent the full range of occupational interests and are confounded with prestige and sex-type.     

职业兴趣的结构：理论与研究

有着近70年历史的职业兴趣结构的研究丰富与发展了其理论,这些理论主要包括：Roe的圆形模型、Holland的六边形模型、Prediger的维度模型、Gati的层级模型以及Tracey-Rounds的球形模型。总结比较这些不同的职业兴趣结构的研究发现,Holland的六边形模型更适合于美国样本(非种族样本)群体,而其他的模型则有待于进一步的考察。研究还表明没有广泛适用的职业兴趣模型,因此,职业兴趣的跨化研究应深入探讨与验证。     

Competing interests: The need to control conflict of interests in biomedical research

Individual and institutional conflict of interests in biomedical research have becomes matters of increasing concern in recent years. In the United States, the growth in relationships — sponsored research agreements, consultancies, memberships on boards, licensing agreements, and equity ownership — between for-profit corporations and research universities and their scientists has made the problem of conflicts, particularly financial conflicts, more acute. Conflicts can interfere with or compromise important principles and obligations of researchers and their institutions, e.g., adherence to accepted research norms, duty of care to patients, and open exchange of information. Disclosure is a key component of a successful conflict policy. Commitments which conflict with a faculty member's primary obligations to teaching, research, administrative responsibilities, or patient care also need attention. Institutional conflict of interests present different problems, some of which are discussed in an analysis of an actual problem posed by two proposed clinical trials. This paper is adapted from a lecture presented to a Symposium on Scientific Integrity, Warsaw, Poland, 23 November 1995. Daniel Steiner was Vice-President and General Counsel of Harvard University (1972–92) and in that capacity became familiar with conflict of interest issues. He is currently Counsel to the Boston law firm. Ropes and Gray, and is Adjunct Lecturer in Public Policy at the John F. Kennedy School of Government. Harvard University.     

The other side of the coin: Vocational interests,interest differentiation and annual income at the occupation level of analysis

This research examined the effects of vocational interest levels and differentiation on annual income. Following the environmental perspective, we investigated whether relationships existed at the occupation level of analysis. Using data from 665 occupations in the U.S. obtained from U.S. Bureau of Labor Statistics and O*Net, we demonstrated that certain vocational interests – namely investigative, enterprising, and realistic interests – were most critical in predicting annual income for occupations. Controlling for interest levels, differentiation not only positively predicted annual income but also moderated each interest's relationship with income. In addition, occupations' education and training requirement partially mediated the effects of interest profiles on income. Our findings reveal the need for a better understanding of how characteristics of an occupation's interest profile may shape the experiences of its workers.     

The Influence of Holland's Vocational Interests on Work-Family Conflict: An Exploratory Analysis

Drawing on a sample of 438 working professionals from various organizations across the central United States, the authors investigated the relationship between Holland's (1959, 1997) RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) model and employee perceptions of work-family conflict. Results revealed that the RIASEC model contributed unique variance in predicting work-family conflict beyond demographic characteristics and the Big Five personality constructs. The RIASEC interests were found to be associated with different dimensions of work-family conflict. These results signal that vocational interests may influence not only work-related attitudes and behaviors (e.g., job satisfaction, performance), but also one's ability to balance work and family demands.     

Success in the first phase of the vocational career: The role of cognitive and scholastic abilities,personality factors,and vocational interests

The present study examines the relationship of cognitive and scholastic abilities, vocational interests, and personality traits with vocational success in the first phase of the vocational career. Drawing on large samples of technicians and industrial clerks, the effects of the covariates on satisfaction and dropout intention in the first months of vocational education and training (VET) were examined. Results show that the sets of predictor variables, especially personality traits and vocational interests, had a large proportion of variance in common, but exhibited different patterns of effects. Whereas in the case of personality traits the predictor-outcome relationships were largely invariant across different fields of VET, vocational interests exhibited a non-invariant pattern of effects that was in line with the congruence hypothesis (Holland, 1997). Vocational interests in the dominant domain characterizing the field of VET were the strongest predictors, whereas interests in the non-dominant VET domains were less important for predicting success. Abilities did not turn out to be important predictors of the markers of success under study. The results underscore the crucial role of personality traits and vocational interests in securing success in the first phase of vocational career.     

Analyzing individual differences in vocational, leisure, and family interests: A multitrait-multimethod approach

This study investigates the latent structure of individual differences in vocational, leisure, and family interests. The participants consisted of 302 French adults who rated their like or dislike for activities based on Holland’s RIASEC typology and presented in three life domains: work, family and leisure. The multitrait-multimethod model proposed by Eid [Eid, M. (2000). A multitrait-multimethod model with minimal assumptions. Psychometrika 65, 241-261.] was used with the vocational interests as standard comparison, and was applied separately on each of the 6 RIASEC types. Results indicated that interests strongly intercorrelated whatever their vocational vs. leisure or family contextualization. However, since these correlations were controlled for measurement error, the results also suggested that the effects of these contextualizations of the activities could not be ignored because they accounted for a non negligible part of the variance for several activities. Theoretical and practical implications are discussed and directions for future research are presented.     

Integrating vocational interests, competencies, and interpersonal dispositions in middle school children

Vocational interests and interpersonal dispositions have been well researched in adults from the perspectives of Holland's RIASEC (1997) model of interests and the Interpersonal Circumplex (IPC), respectively. Few studies have applied either model to children and no studies have examined their overlap in children. A vector fitting procedure was applied to data from adults to demonstrate the intersection of vocational interests and interpersonal dispositions from the perspective of the IPC. The same procedure was then applied to interests and competencies and interpersonal dispositions in a sample of sixth grade children. Plotting the vocational variables within interpersonal space defined by the IPC showed the specific interpersonal aspects of vocational interests in young adults and interests and competencies in late childhood. Half of the interests had associations with the IPC that were consistent across adults and children, while the remaining interests had associations that were unique to children.     

Correspondence of children's anticipated vocations, perceived competencies, and interests: Results from an Italian sample

Relations among anticipated vocations, self-assessments of competence, and interests in sample of 190 Italian children were examined. Children were asked what activities they liked, those they thought they were good at, and what job they expected when they grew up. The responses were coded into RIASEC Holland codes and agreement across the three questions was examined using kappa statistics. Results indicated that there was no relation between anticipated occupations and either interest or perceived competence. Thus, these anticipated occupations appear to be based on unrealistic criteria and the validity of studying such early expressions of interest is questionable. Conversely, results demonstrated a correspondence between interest and competence and this correspondence was similar for boys and girls and increased with age.     

The relation of self-efficacy and interests: a meta-analysis of 60 samples

This study empirically synthesizes and evaluates studies that have examined the relation between vocationally relevant domains of self-efficacy and interests. We conducted a meta-analytic review of 60 empirical independent samples (N=39,154) in which relations between self-efficacy and interests had been examined. Fifty-three of these samples (N=37,829) included parallel measures of the constructs. Relations between parallel measures of Holland’s RIASEC themes, the specific dimensions of art, math, science and math/science combined, and traditionally female and male occupations are also presented. Results demonstrated that self-efficacy and interests are independent constructs that correlate moderately. Differences by sex, measure, and age group are noted. Future directions for research regarding links between self-efficacy and interests are discussed.
