ADHD 아동의 하위 유형에 따른 전두엽집행기능 연구-WCST 수행을 중심으로- = Executive functioning in ADHD subtypes:primarily in WCST

국문 초록 (Abstract)

본 연구는 ADHD(Attention Deficit Hyperactivity Disorder) 아동을 주의력결핍우세형, 혼합형으로 하위유형을 구분하여 통제집단으로 설정한 신경증아동집단과 전두엽집행기능을 비교하였다. 전두엽집행과제로는 WCST(위스컨신카드분류검사)를 사용하였으며, 이외에도 KEDI-WISC(지능검사)와 ADS(연속주의력검사) 수행을 비교하였다. 연구대상은 ADHD 주의력결핍우세형 5명, ADHD 혼합형 12명, 신경증 19명이였다. 연구 결과, 전체 지능과 동작성 지능, 산수, 숫자, 기호, 토막에서 주의력결핍 우세형이 신경증아동보다 유의하게 낮게 나타났다. 그리고 WCST의 정반응수, 오반응수, 보속반응수, 보속오류수, 개념수준반응수, 완성범주수에서 주의력결핍우세형이 혼합형과 신경증 아동보다 수행이 빈약하게 나타났다. 또한 ADS의 누락오류와 WCST의 지표들간에 유의한 상관이 있었다. 마지막으로 본 연구의 제한점, 후속연구에 대한 제안을 논의하였다.

다국어 초록 (Multilingual Abstract)

This study was intended to compare two ADHD subtypes(N; inattentive type=5, combined type=12) and neurotic group(n=19) in their frontal executive functioning. WCST used as a frontal-executive task, and KEDI-WISC, ADS were administered. ADHD inattentive type demonstrated deficits in full scale IQ, performance IQ, digit span, arithmetic, digit symbol. So after controlling for IQ, total correct, total error, perseverative errors, perseverative response, conceptual level response were low score in ADHD's inattentive type than combined type and neurotic group. And ADS's ommission error and WCST are correlated significantly. These results suggested that inattention was significantly associated with executive function weakness, whereas hyperactivity-impulsivity was not independently associated with executive function performance. Limitation of these studies and further study directions were also discussed.
