Do vocational interests matter for the selection of romantic partners? Evidence from variable‐ and couple‐centered approaches

The present study links the person–environment fit theory of vocational interests (VI) with the research on the selection of romantic partners. Empirically, we explore the assortment for VI in 215 heterosexual romantic partners. Using both the variable‐centered (VCA) and couple‐centered (CCA) approaches, we test the hypotheses on positive versus negative assortment, initial assortment versus convergence, and active assortment versus social homogamy. A modest to moderate positive assortment was found for Realistic, Investigative, Artistic, and Social interests but not Conventional interests, whereas evidence of couple similarity in Enterprising interests was less consistent. A moderate level of positive assortment was identified in couples when full interest profiles were evaluated. The results indicate an initial and active assortment rather than convergence or social homogamy effects. The analysis also shows that the assortment for interests represents an independent preference that cannot be easily seen as a by‐product of the assortment in the five‐factor personality traits. These findings highlight the importance of VI in the active selection of romantic partners. We discuss implications for future research and practice.
