AbstractIntroductionThere is a gap in the literature on the romantic relationships of adopted adolescents. To address this issue, the present study has three aims: (1) to explore differences between adopted and non‐adopted adolescents in terms of their involvement in and the length of their romantic relationships; (2) to explore the quality of these relationships; and (3) to analyze associations between affective relationships and well‐being in both groups.MethodThe sample comprised 276 adopted (64.5% girls; mean age 16.3 years, 73.9% international adoptees) and 276 non‐adopted (48.3% girls; mean age 16.3 years) adolescents, all of whom participated in the Spanish Health Behaviour in School‐aged Children survey.ResultsSimilar romantic relationship rates and lengths were found among adoptees and non‐adoptees, as well as between international and domestic adoptees. Adoptees reported more emotional support and conflicts in their romantic relationships than their non‐adopted peers. Finally, associations between the quality of the romantic relationships and well‐being were similar for both groups, with more conflicts being linked to lower levels of well‐being, and more emotional support and affection correlating with higher levels of well‐being.DiscussionThe data suggest more similarities than differences between adopted and non‐adopted adolescents. However, although this indicates that romantic relationships are yet another example of recovery for adopted boys and girls, further research is required, with larger and more diverse samples from multiple countries, to explore the differences observed in more detail.
