has found that the additional risks faced by adoptees are largely confined to adolescence. Young adult adoptees were shown to be alike with adults from biological families and scored better than adults raised in alternative family types including single parent and step-families. Moreover, while adult adoptees showed more variability than their non-adopted peers on a range of psychosocial measures, adult adoptees exhibited more similarities than differences with adults who had not been adopted. There have been many cases of remediation or the reversibility of early trauma. For example, in one of the earliest studies conducted, Professor Goldfarb in England concluded that some children adjust well socially and emotionally despite their negative experiences of institutional deprivation in early childhood. Other researchers also found that prolonged institutionalization does not necessarily lead to emotional problems or character defects in all children. This suggests that there will always be some children who fare well, who are resilient, regardless of their experiences in early childhood. Furthermore, much of the research on psychological outcomes for adoptees draws from clinical populations. This suggests that conclusions such that adoptees are more likely to have behavioral problems such as ODD and ADHD may be biased. Since the proportion of adoptees that seek mental health treatment is small, psychological outcomes for adoptees compared to those for the general population are more similar than some researchers propose. Mental health Adopted children are more likely to experience psychological and behavioral problems than non-adopted peers. Children who were older than four at the time of their adoption experience more psychological problems than those who were younger. According to study in the UK, adopted children can have mental health problems that do not improve even four years after their adoption. Children with multiple adverse childhood experiences are more likely to have mental health problems. The study suggests that to identify and tread mental health problems early, care professionals and the adopting parents need detailed biographical information about the child's life. Another study in the UK suggests that adopted children are more likely to suffer from post-traumatic stress (PTS) than the general population. Their PTS symptoms depend on the type of adverse experiences they went through and knowledge of their history offers an option for tailored support. Adoptees of LGBT parents There is evidence that shows the adoptees of LGBT families and those in heterosexual families have no significant differences in development. One of the
