“…Moreover, adolescence, commonly considered a challenging stage of life, could be a particularly difficult time for adoptees considering the special relevance of issues about losses, identity, and origin in this population (Smith, Howard, & Monroe, ). However, research on adoption in adopted adolescents has not provided conclusive evidence on attachment deficits and aggression problems for a number of reasons: (1) studies on attachment in adopted adolescents are still sparse (Escobar, Pereira, & Santelices, ); (2) changes in adolescents’ attachment system may result in different attachment‐related outcomes, depending on the distinct measurement approaches in this developmental period; (3) there is a remarkable lack of research into adopted adolescents’ aggressiveness despite their being at special risk for aggression problems; and (4) most studies only compared adopted teens with nonadopted pairs, neglecting the fact that differences in adoption outcomes vary depending on type of adoption and age of the adopted adolescent (Palacios, Sánchez‐Sandoval, & León, ) and comparison groups (Juffer, van IJzendoorn, & Palacios, ). Thus, more studies are needed to examine differences in adopted adolescents’ attachment security and aggressiveness, considering not only community nonadopted pairs as the comparison group, but also adolescents being treated for aggressive problems.…”
