Parents' psychological warmth has been consistently identified as being significantly related to psychological adjustment in children and adolescents. Regardless of culture, ethnicity or geographical location about a quarter of the variation in youths' psychological adjustment is accounted for by parents' perceived warmth. However, little research into this has been done among the U.S.'s Korean community despite the fact that this commmunity has trebled in number in the last twenty years. A study of 103 Korena Americans aged between the ages of 11 and 14 has found that low perceived maternal and paternal warmth did lead to a decline in the children's overall psychological adjustment. Low maternal warmth was particularly related to the children's poor psychological adjustment.
