Job characteristics and personality change in young adulthood: A 12-year longitudinal study and replication.

OBJECTIVE: Personality changes are related to successfully performing adult occupational roles which require teamwork, duty, and managing stress. However, it is unclear how personality development relates to specific job characteristics that vary across occupations. METHOD: We investigated whether 151 objective job characteristics, derived from the Occupational Information Network (O*NET), were associated with personality levels and changes in a 12-year longitudinal sample followed over the school to work transition. Using cross-validated regularized modeling, we combined two Icelandic longitudinal datasets (total N = 1054) and constructed an individual-level, aggregated job characteristics score that maximized prediction of personality levels at baseline and change over time. RESULTS: The strongest association was found for level of openness (0.25), followed by conscientiousness (0.16) and extraversion (0.14). Overall, aggregated job characteristics had a stronger prediction for personality intercepts (0.14) than slopes (0.10). These results were subsequently replicated in a U.S. sample using levels of the Big Five as the dependent variable. This indicates that associations between job characteristics and personality are generalizable across life stages and nations. CONCLUSIONS: Our findings suggest that job titles are a valuable resource that can be linked to personality to better understand factors that influence psychological development. Further work is needed to document the prospective validity of job characteristics across a wider range of occupations and age.

Personality Changes Predict Early Career Outcomes: Discovery and Replication in 12-Year Longitudinal Studies.

In this research, we examined whether personality changes from adolescence to young adulthood predicted five early career outcomes: degree attainment, income, occupational prestige, career satisfaction, and job satisfaction. The study used two representative samples of Icelandic youth (Sample 1: n = 485, Sample 2: n = 1,290) and measured personality traits over 12 years (ages ~17 to 29 years). Results revealed that certain patterns of personality growth predicted career outcomes over and above adolescent trait levels and crystallized ability. Across both samples, the strongest effects were found for growth in emotional stability (income and career satisfaction), conscientiousness (career satisfaction), and extraversion (career satisfaction and job satisfaction). Initial trait levels also predicted career success, highlighting the long-term predictive power of personality. Overall, our findings show that personality has important effects on early career outcomes-both through stable trait levels and how people change over time. We discuss implications for public policy, for theoretical principles of personality development, and for young people making career decisions.

Life goal development, educational attainment, and occupational outcomes: A 12-year, multisample longitudinal study.

Life goals play a major role in shaping people's lives and careers. Although life goals have prior documented associations with occupational and other life outcomes, no prior studies have investigated associations between life goal development and occupational outcomes. Using two representative samples of Icelandic youth (Sample 1: n = 485, Sample 2: n = 1,339), followed across 12 years from adolescence to young adulthood, we examined life goal development and associations with educational attainment and a wide range of occupational outcomes. We found that life goals had relatively high rank-order and profile stability across the 12 years. Most life goals decreased in importance during the transition from adolescence to young adulthood, except for family- and community-related goals, pointing to a continued focus on building social relationships in young adulthood. We also found meaningful variation in change at the item level within certain goal domains. Furthermore, adolescent levels of life goals, as well as changes in certain goals, predicted educational attainment and occupational outcomes in young adulthood. This suggests that life goals motivate career behaviors beginning at an early age and that subsequent changes in certain life goals also matter for educational and occupational outcomes. Dominance analyses revealed that education and prestige life goals were generally the strongest predictors of future outcomes. Overall, these results highlight the importance of life goal development in predicting later educational attainment and occupational outcomes.

Holland in Iceland revisited: an emic approach to evaluating U.S. vocational interest models.

An emic approach was used to test the structural validity and applicability of Holland's (1997) RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) model in Iceland. Archival data from the development of the Icelandic Interest Inventory (Einarsdóttir & Rounds, 2007) were used in the present investigation. The data included an indigenous pool of occupations and work-task items representing Iceland's world of work that had been administered to a sample of 597 upper secondary school students. Multidimensional scaling analysis and property vector fitting using Prediger's (1981) work-task dimensions were applied to the item responses to test if the RIASEC model could be identified. The results indicated that a 4-dimensional solution better explains the interest space in Iceland than Holland's 2-dimensional RIASEC representation. The work-task dimension of People-Things and the Sex-Type and Prestige dimensions were located in the 1st and 2nd dimensions of the multidimensional scaling solution, but Data-Ideas, a dimension critical to the RIASEC model, was not. The 3rd and 4th dimensions did not correspond to any dimensions previously detected in structural studies in the United States and seem to be related to specific ecological, cultural, and political forces in Iceland. These results demonstrate the importance of selecting representative indigenous occupations and work tasks when evaluating the RIASEC model. The present study is an example of the next step in a comprehensive cross-cultural research program on vocational interests, an emic investigation.

Developmental structure of personality and interests: A four-wave, 8-year longitudinal study.

Personality traits and vocational interests capture different aspects of human individuality that intersect in certain ways. In this longitudinal study, we examined developmental relations between the Big 5 traits and RIASEC vocational interests over 4 timepoints from late adolescence to young adulthood (age 16-24) in a sample of Icelandic youth (N = 485) well-representative of the total student population. Results showed that interests and personality traits were similarly stable over time, but showed different patterns of mean-level change. There was evidence of personality maturation but a lack of cumulative changes in interest levels. For the most part, gender differences in developmental trends were minimal. In addition, latent growth curve analyses revealed broad and specific correlated changes between personality and interests. Changes in general factors of personality and interests were moderately related (r = .32), but stronger correlated changes were found among specific personality-interest pairs that share situational content. Overall, results reveal how interests and personality are related across different types of continuity and change. While there was little correspondence between group-level changes, substantial correlated change occurred at the individual level. This means that when a person's personality changes, their interests tend to change in predictable ways (and vice versa). Integrative theories that link different aspects of psychological functioning can benefit by incorporating these findings. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
