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.     

Cognitive complexity and interest crystallization

The relationship between cognitive differentiation and vocational interest crystallization was investigated. Ninety-six career counselees filled in the RAMAK vocational interest inventory. Then, each subject's occupational constructs were elicited by comparing triads of occupations. Finally each subject rated 24 occupations on his/her elicited constructs. Interest crystallization was defined on the basis of the salient scales in the interest inventory, taking into account the structure of interests. Cognitive differentiation was measured by between- and within-constructs differentiation, ordination, intensity, and conflict and by the difference between the perception of an ideal and a rejected occupation. The relationships between the various measures of cognitive differentiation were generally low, suggesting that they capture different aspects of cognitive complexity. The results indicate that interest crystallization is related to the between-construct differentiation, but not to the other measures of cognitive complexity. The implications for research and counseling are discussed.     

Relation of occupational knowledge to career interests and competence perceptions in Italian children

The relations of differential occupational knowledge with interests and competence perceptions in children as well as how these relations were moderated by gender and grade were examined in this study using an Italian sample. Data were collected from samples of elementary school and middle school children (N = 539). The Inventory of Children's Activities—Revised (ICA-R; Tracey & Ward, 1998) was used to assess children's interest and competency perceptions in various activities associated with the Holland's RIASEC types. The Occupational Knowledge Scale (OKS) was created for this study, and consisted of a representative sampling of occupational titles to which children indicated their knowledge. Hierarchical regression results indicated a relationship between knowledge, interests, and competence perceptions in children. With regard to overall knowledge, no relationship was found between general knowledge and either grade or gender. More specific examination of the type of knowledge as it varied across the dimensions of People–Things, and Data–Ideas demonstrated that there appeared to be a specific pattern relating interest, gender, and grade to knowledge of occupations. For knowledge of people relative to things occupations, higher interest, higher grade level, and being female predicts stronger knowledge of people occupations. It was also found that interest in ideas predicts stronger knowledge of ideas occupations, and being male predicts stronger knowledge of high prestige occupations. Generally, competence perceptions did not have a unique relation with one's knowledge of People–Things, Ideas–Data, or Prestige; however, girls who reported higher competence had greater knowledge of ideas occupations.     

The relationship between vocational interests and the location of an ideal occupation in the individual's perceived occupational structure

The relationship between vocational interests and the location of an ideal occupation in the perceived occupational structure of career counselees was investigated. Ninety-six career counselees completed the RAMAK vocational interest inventory. Then, the occupational constructs of each subject were elicited by the career grid procedure. Finally, each subject rated 24 occupations and his/her ideal and rejected occupations on his/her own elicited constructs. The intrasubject analyses indicated that the preferences for occupational fields as measured by the interest inventory reflect the fields' proximity to an ideal occupation in the individual's perceived occupational structure. The implications for career development are discussed.     

Dimensions underlying Holland's hexagon: Missing link between interests and occupations?

Holland uses a hexagon to model relationships among his six types of vocational interests. This paper provides empirical evidence regarding the nature of the interest dimensions underlying the hexagon. Two studies are reported. Study 1 examines the extent to which two theory-based dimensions—data/ideas and things/people—fit 27 sets of intercorrelations for Holland's types. Three of the data sets involve the mean scores of career groups (total of 228 groups and 35,060 individuals); 24 involve the scores for individuals (total of 11,275). Study 2 explores the heuristic value of the data/ideas and things/people dimensions by determining whether they contribute to the understanding of why interest inventories work. Two data sets covering a total of 563 occupations are used to calculate correlations between the vocational interests of persons and the tasks which characterize the persons' occupations. Each occupation's principal work tasks are determined from job analysis data obtained from the U.S. Department of Labor. Study 1 results provide substantial support for the theory-based dimensions. Study 2 results suggest that interest inventories “work” primarily because they tap activity preferences which parallel work tasks. Counseling and research applications of the data/ideas and things/people dimensions are suggested and implications for interest assessment are noted.     

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.     

Utilizing occupational complexity levels in vocational interest assessments: Assessing interests for STEM areas

With an aim to improve vocational interest assessments geared toward the Science, Technology, Engineering, and Mathematics (STEM) areas, we developed a new assessment by incorporating occupational complexity levels. Occupations which correspond to Holland's realistic and investigative themes were identified together with their complexity levels using the information in the Dictionary of Holland Occupational Codes. How the required skills, abilities, and work activities differ in occupations with different complexity levels was identified using the Occupational Information Network. Two studies (N = 691 total) were conducted to assess reliability and validity of a measure of STEM Interest Complexity assessing the level of interests for STEM, which was developed based on the information obtained from these occupation databases. Construct validity was demonstrated with factor analyses and based on associations with traditional interest assessments, cognitive abilities, and theoretically-related constructs. Concurrent criterion-related validity was demonstrated based on associations with attachment to STEM, intentions to persist in and further pursue a STEM field, intentions to choose a complex occupation, college major satisfaction, and STEM-related GPA. Dominance analyses indicated that the relative contribution of the STEM Interest Complexity measure exceeded that of traditional interest assessments in the prediction of criteria. The usefulness of integrating a dimension of level and consulting occupation information databases in developing vocational interest assessments are discussed.     

The stability of aspect-based career preferences and of the recommended list of occupations derived from them

Career-related preferences (e.g., team work, independence, length of training, income), which are an elaboration and extension of vocational interests, are one of the cornerstones that guide individuals to promising occupations recommended for further exploration. These preferences are informative and can serve individuals and their career counselors only if they are reliable and stable. Study 1 tested the two-week reliability of 31 career-related preferences of 213 freshman students and the two-year stability of the preferences of 132 of these students. Both the within-aspect preferred levels (e.g., only indoors most preferred, but mostly indoors also acceptable) and the importance of the aspects were elicited. The median within-participant two-week reliability was .85 for preferred levels and .64 for aspect importance; the median two-year stabilities were .75 and .51, respectively. In Study 2, the preferences elicited in Study 1 were used to derive a list of recommended occupations compatible with each participant's preferences at Time 1, Time 2 (2 weeks later), and Time 3 (2 years later), using a compensatory-model-based fit index. The percentage of identical occupations in the lists of the top ten recommended occupations was quite high — 62% for Time 1 and Time 2, and 54% for Time 1 and Time 3. The theoretical and practical implications of the reliability and stability of recommendations based on aspect-based career preferences are discussed.

Holland's vocational models: A study of work groups and need satisfaction

This study was designed to investigate two topics: (1) the concurrent validity of Holland's theory for employed men, and (2) the pattern of needs associated with occupations exemplifying each of Holland's vocational models. Concurrent validity was investigated by administering the Vocational Preference Inventory to 230 male workers well established in occupational milieus that match Holland's six vocational environments. With the exception of the Realistic scale of the VPI, the five remaining vocational scales distributed eight work groups, identified as representative of each of Holland's six vocational models, in a comparable fashion according to their interests. Empirical results on two nonvocational scales (Masculinity and Status) support Holland's vocational models.     

Matching Abilities to Careers for Others and Self: Do Gender Stereotypes Matter to Students in Advanced Math and Science Classes?

Interest in STEM (science, technology, engineering, and mathematics) careers falls off more quickly for young women than for young men over adolescence, and gender stereotypes may be partially to blame. Adolescents typically become more stereotypical in their career interests over time, yet they seem to become more flexible in applying stereotypes to others. Models of career interest propose that career decisions result from the alignment of self-perceived abilities with occupation-required skills and that gender stereotypes may influence this process. To investigate the discrepancy between applying stereotypes to self and others, we examined if these models can be applied to perceptions of others. Focusing on students from fifth grade through college enrolled in advanced STEM courses, we investigated how STEM occupational stereotypes, abilities, and efficacy affect expectations for others’ and own career interests. U.S. participants (n = 526) read vignettes describing a hypothetical male or female student who was talented in math/science or language arts/social studies and then rated the student’s interest in occupations requiring some of those academic skills. Participants’ self-efficacy, interest, and stereotypes for STEM occupations were also assessed. Findings suggest that ability beliefs, whether for oneself or another, are powerful predictors of occupational interest, and gender stereotypes play a secondary role. College students were more stereotypical in their ratings of others, but they did not manifest gender differences in their own STEM self-efficacy and occupational interests. Experiences in specialized STEM courses may explain why stereotypes are applied differentially to the self and others.     

Relating the Spherical representation of vocational interests to the HEXACO personality model

The present study extends previous research on interests–personality relations by comparing recent models of vocational interests (using the Personal Globe Inventory; PGI, Tracey, 2002) and personality (using the HEXACO-PI-R; Ashton, Lee, & de Vries, 2014) with each other. First, the structure of the Spherical representation was adequately replicated in a Dutch sample (N = 656). Second, in so far as comparisons were possible, the relations between interests and personality were found to be congruent with previous findings. Third, Prestige interests, the defining feature of the Spherical representation, were related, albeit weakly, to Openness to Experience and to Extraversion. Last of all, Honesty–Humility and Openness to Experience were related to profile elevation in interest scores. All results were obtained for normative and ipsatized scales, revealing several meaningful differences in interests–personality relations depending on the type of interest scoring procedure.     

Vocational interests of intellectually gifted and highly achieving young adults

Background. Vocational interests play a central role in the vocational decision‐making process and are decisive for the later job satisfaction and vocational success. Based on Ackerman's (1996) notion of trait complexes, specific interest profiles of gifted high‐school graduates can be expected. Aims. Vocational interests of gifted and highly achieving adolescents were compared to those of their less intelligent/achieving peers according to Holland's (1997) RIASEC model. Further, the impact of intelligence and achievement on interests were analysed while statistically controlling for potentially influencing variables. Changes in interests over time were investigated. Sample . N= 4,694 German students (age: M= 19.5, SD= .80; 54.6% females) participated in the study (TOSCA; Köller, Watermann, Trautwein, & Lüdtke, 2004 ). Method. Interests were assessed in participants’ final year at school and again 2 years later (N= 2,318). Results . Gifted participants reported stronger investigative and realistic interests, but lower social interests than less intelligent participants. Highly achieving participants reported higher investigative and (in wave 2) higher artistic interests. Considerable gender differences were found: gifted girls had a flat interest profile, while gifted boys had pronounced realistic and investigative and low social interests. Multilevel multiple regression analyses predicting interests by intelligence and school achievement revealed stable interest profiles. Beyond a strong gender effect, intelligence and school achievement each contributed substantially to the prediction of vocational interests. Conclusions . At the time around graduation from high school, gifted young adults show stable interest profiles, which strongly differ between gender and intelligence groups. These differences are relevant for programmes for the gifted and for vocational counselling.     

career concerns of unemployed u.s. war veterans: suggestions from a cognitive information processing approach

The authors examined U.S. war veterans' career concerns (e.g., interests, personality, barriers, career thoughts) to provide possible avenues for research‐based and theory‐driven intervention. The veterans who participated in the study were receiving mental health, substance abuse, and vocational services at a residential facility. Participants were found to have interests in all RIASEC (J. L. Holland, B. A. Fritzsche, & A. B. Powell, 1994; J. L. Holland & G. D. Gottfredson, 1994) interest areas, and negative career thinking was found to be related to a variety of negative indicators. Suggestions are provided for working with veterans using the Cognitive Information Processing approach to career decision making.     

Strong Vocational Interest Blank basic interest clusters and occupational satisfaction

A Q-factor analytic technique applied to the Strong Vocational Interest Blank (SVIB) basic interest scales of 156 males yielded three bipolar factors described as conceptual (applied vs theoretical thinking); interpersonal (people vs things); and volitional (autonomy vs structure). From these results the investigators constructed a model for categorizing occupations into corresponding vocational areas: managerial vs academic, social vs physical sciences, and professional vs technical. Each individual's primary interest area and occupational status relative to the six corresponding areas was then determined. The degree of fit between interests and job categorization related significantly to ratings of job satisfaction (p < .001). Those findings are complementary to Holland's notion that interests are expressions of psychological needs and to Lofquist and Dawis' perception of interests and jobs as needs and need reinforcers.     

Career-Related Interests and Values,Perceived Control,and Acculturation of Asian-American and Caucasian-American College Students1

The present study compares the career-related interests and values of Asian-American and Caucasian-American college students and explores the relationships among career interests, perceived control, and acculturation. Career-related interests were defined by Holland's (1959, 1985a) model of vocational personality types and work environments, and career-related values were defined by Schein's (1987) career anchors. The Career Anchor Inventory (Nordvik, 1991), the Self-Directed Search (Holland, 1991), and the Spheres of Control Scale (Paulhus & Van Selst, 1990), were completed by 184 Asian-American and 130 Caucasian-American undergraduate students. The Asian-Americans also completed the Suinn-Lew Asian Self-Identity Acculturation Scale (Suinn, Rickard-Figueroa, Lew & Vigil, 1987). In comparison to Caucasian-American students, Asian-American students showed higher interest in the Investigative and Conventional vocational categories, but lower interest in the Social category. Asian-American subjects were lower in perceived control in the Personal and Interpersonal spheres. Among the Asian-Americans, acculturation was positively correlated with perceived control in the Personal and Interpersonal spheres and with the Enterprising vocational category. Acculturation was negatively correlated with Investigative and Conventional interests.     

Links between family gender socialization experiences in childhood and gendered occupational attainment in young adulthood

Gendered occupational segregation remains prevalent across the world. Although research has examined factors contributing to the low number of women in male-typed occupations – namely science, technology, engineering, and math – little longitudinal research has examined the role of childhood experiences in both young women's and men's later gendered occupational attainment. This study addressed this gap in the literature by examining family gender socialization experiences in middle childhood – namely parents' attitudes and work and family life – as contributors to the gender typicality of occupational attainment in young adulthood. Using data collected from mothers, fathers, and children over approximately 15 years, the results revealed that the associations between childhood socialization experiences (~ 10 years old) and occupational attainment (~ 26 years old) depended on the sex of the child. For sons but not daughters, mothers' more traditional attitudes toward women's roles predicted attaining more gender-typed occupations. In addition, spending more time with fathers in childhood predicted daughters attaining less and sons acquiring more gender-typed occupations in young adulthood. Overall, evidence supports the idea that childhood socialization experiences help to shape individuals' career attainment and thus contribute to gender segregation in the labor market.     

Phenotypic and genetic relationships between vocational interests and personality

Relationships between personality and vocational interest factors were examined at the phenotypic and genetic levels. Twins and siblings (N = 516) completed self-report personality and vocational interest scales. Following factor analyses of each scale, five personality and six vocational interest factors were extracted. At the phenotypic level, correlations between personality and vocational interests ranged from zero to .33. Heritability estimates of the scales showed that genetic components accounted for 0–56% of the variance for the vocational interest factors and 44–65% for the personality factors. Genetic correlations between the two areas ranged from zero to .50. The results suggest that personality is related to some vocational interest dimensions and that some of these observed relationships have a common genetic basis.     

A longitudinal and multi-method examination of interest–occupation congruence within and across time

Remarkably little research has addressed change and stability in person–environment fit across time. The objective of the current study was to address this gap in the literature by investigating Holland interest–occupation congruence across time for a sample of college alumni (N = 167) that were tracked during the first third of their professional career. Congruence was examined in all its complexity, including a repeated assessment of both occupations and interests, the use of objective (O*NET) and subjective (self-report) environment assessment methods, and adopting sophisticated congruence calculation methods (i.e., Euclidean distance and profile correlation). This resulted in a total of 12 interest–occupation comparisons within and across time that could be related to general and career specific well-being. The results first indicated moderate levels of stability in interests and occupations across the 15-year time interval, yet also with room for change. Congruence analyses indicated significant interest–occupation fit at the beginning of the career and 15 years later, with the magnitude of congruence slightly varying depending on which occupation assessment and which congruence method was used. Profile correlation congruence did not change over time in absolute terms and evidenced relative stability. Euclidean distance indices had little relative stability over time but did manifest some absolute changes in levels of congruence. Finally, job change moderated the association between interest–occupation congruence and life satisfaction in such a way that higher levels of satisfaction were reported only when little job change was present.     

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.
