The developmental stage of young adulthood, the period from one's late twenties through thirties, has grown in attention and research focus among general populations. However, little is known about the adjustment of adopted individuals during this phase. The present study sought to expand our understanding of the various patterns of adoptee adjustment in young adulthood. Latent profile analysis was used to identify profiles across eight domains of functioning spanning physical and mental health to relationships, achievement, and engagement. Three profiles were identified, demonstrating varying levels of adult functioning. Adoption related and non-adoption related variables were explored using a series of multinomial logistic regressions to determine which factors differentiated between profiles. It appears that, although some adoption related variables remain significant in young adulthood, non-adoption related variables are more strongly linked to adoptee adjustment at this developmental stage. Implications and future directions for clinical care and research are discussed.
