The present meta-analysis used meta-analytic techniques to determine the patterns of mean-level change in vocational interests from early adolescence (age 12) to the end of emerging adulthood (age 24.9). Results showed that vocational interests show a clear pattern of normative change. Across gender, Investigative, Artistic, Social and Enterprising interests were found to increase across the studied period, with the greatest changes in mean-levels occurring during middle- through late-adolescence into emerging adulthood. Conventional interests were found to increase for women and decrease for men during the same period. However, contrary to stereotypes, Realistic interests increased in women and decreased in men. Gender was also a moderating factor in mean-level changes of basic interests. Longer studies showed greater change. The ages at which the greatest change occurred were markedly different across general and basic interest categories, suggesting differential rates or timelines of development across the broad band of interests.
