The increase in transracial adoption in modern society has not been without some controversy over its practice. Conflicting studies, have exposed and given rise to greater sensitivity to the impact of transracial adoption on adoptees-. As noted, prior studies have indicated that Korean adoptees adjust well to their environment (Feigelman & Silverman, Kim, 1977, 1978; Simon, 1974); however, some studies indicate a negative outcome (Chestang, 1972; Chimezie, 1975) and some ethnic groups (i.e., Native Americans and The National Association of Black Social Workers) have discouraged the practice of transracial adoption. In an attempt to clarify such issues surrounding transracial adoption, the purpose of this study was to explore the impact of adoption on adult Korean adoptees.This study examined whether acculturation, assimilation, cultural identity, age of placement of Korean adoptees, and revisiting Korea play a role in self-concept. In addition, this study wanted to look at whether the positive initial adjustment found in Kim's (1977; 1978) studies continued into adulthood for Korean adoptees. Adjustment was based upon self-concept. The results from this study indicated that acculturation, assimilation, cultural identity, placement of Korean adoptees, and revisit of Korea had little influence in self-concept. As noted, the results indicated that: 1) acculturation was only related to Verbal self-concept; 2) revisiting Korea did not predict self-concept; however, cultural identity did play an important part in self concept; 3) age of placement of Korean adoptees related only to Verbal, Math, and Honesty self-concept; and 4) in general, positive adjustment based upon self-concept appeared to continue into adulthood for Korean adoptees.In summary, adjustment for Korean adoptees appeared to continue into adulthood. In addition, cultural identity appeared not to relate to Korean adoptees' self-concept. However, as noted, there needs to be further studies due to the limitations of this study, particularly the measurements. / Department of Counseling Psychology and Guidance Services
