This study examined the psychosocial characteristics of Korean girls with Turner Syndrome(TS) compared with those of age-matched, healthy control group. 36 girls with TS aged from 10 to 18 years and their parents were recruited. Also, 36 age-matched healthy girls and their parents prticipated in the study for the control group. Participants complete the Korean-Child Behavior Checklist(K-CBCL), Self Concept Inventory(SCI), Children’s Depression Inventory(CDI), the Revised Children’s Manifest Anxiety Scale(RCMAS), and Pediatric Quality of Life Inventory™ Version 4.0(PedsQL™ 4.0). Girls with TS reported more total behavior problems, internalizing behavior problems, immaturity, thought problems, and inattention thatn the control group.

Meanwhile, no significant difference in anxiety between girls with TS and the healthy control was found. The results of the study support previous studies. In addition, implications of the study are discussed.
