뇌성마비아동의 지능검사 방법에 대한 비교 고찰

Abstract

[한글]

본 연구의 목적은 한국판 그림 지능검사인 K-PTI가 언어 및 동작장애를 가진 뇌성마비 아동의 일반적 지능을 측정하기에 타당한 측정 도구인지를 검토하는데 있다.

연구대상은 4-8세의 정상아동 30명과 언어 및 동작장애를 수반한 뇌성마비아동 30명이였고, 본 연구에 사용된 지능검사는 K-WISC와 K-PTI 이었다

일반적 지능을 측정하는데 있어서 K-PTI의 타당성은 정상아동이 K-WlSC와 K-PTI에서 획득한 지능지수의 상관관계를 산출하여 추정하였고, 뇌성마비아동의 지능측정도구로서 K-PTI의 타당성은 뇌성마비아동이 K-WlSC와 K-PTI에서 획득한 지능지수간의 차이를 통하여 추정하였다.

본 연구의 결과는 다음과 같이 요약된다.

첫째, 정상아동은 K-WISC와 K-PTI 지능지수간에 유의한 차이를 보이지 않았으나( P> .05 ), 언어 및 동작장애를 수반한 뇌성마비아동은 K-WlSC보다 K-PTI에서 유의하게 높은 지능지수를 나타냈다 ( P< .001).

둘째, K-WISC와 K-PTI 지능지수간의 상관관계에서 정상아동집단은 뇌성마비아동 집단보다 유의하게 높은 상관관계를 가졌다. 정상아동 집단에서 K-PTI 평균 지능지수는 110.80, 표준편차는 12.45이고, K-WlSC 평균 지능지수는 110.06, 표준편차는 13.25로서 높은 상관관계를 보였다(r = .95). 따라서 K-PTI는 4-8세 아동의 일반적 지능을 측정하는 도구로서 합당하다고 할 수 있겠다. 뇌성마비아동은 K-WISC보다 K-PTI에서 유의하게 높은 지능지수를 나타냈다( P< .001 ). K-PTI의 평균지능지수는 83.63, 표준편차는 11.70이였고, K-WISC의 평균 지능지수는 75.56, 표준편차는 12.27이었다. 이는 K-PTI가 언어표현과 손동작을 필요로 하지 않아서, 언어 및 동작장애를 수반한 뇌성마비아동이 K-PTI를 수행하는데 큰 지장이 없었기 때문인 것으로 추측된다. 이러한 맥락에서 볼 때 K-PTI는 뇌성마비아동의 일반적 지능을 측정하는데 비교적 타당성 있는 측정 도구가 될 것이다.

A Concurrent Validity Study of the K-PTI with the K-WISC in Normal and Cerebral

Palsy Children

The purpose of this study is to investigate the validity of the K-PTI (Korean

Pictorial Test of Intelligence) in measuring the general intellectual ability of

cerebral palsy children with language/motor Impairments.

The subjects were 30 normal and 30 cerebral palsy children, respectively, aged

between 4 and 8 years. The tools used to measure the subject's intelligence were

the K-PTI and the K-WISC (Korean Wechsler Intelligence Scale for Children). The

study was carried out between March, 1985 and May, 1985.

The experimenter administered the K-PTI and the K-WISC to both normal and

cerebral palsy children respectively. The IQs of the two groups on the K-PTI and

the K-WISC were analyzed as follow; (1) A correlation between the normal children's

IQ's measured by the K-PTI and by the K-WISC was computed: and (2) in order to

investigate the validity of the K-PTI with cerebral palsy children's the cerebral

palsy children's PTI IQ scores were compared with their K-WISC IQ scores.

In the normal children, the correlation between the K-PTI and the K-WISC scores

was 0.95. This data reveals that the K-PTI has adequate validity for measuring the

general intellectual ability of normal children. In cerebral palsy children, the

mean score on the K-PTI was 83.6, with a SD of 11.7, while the metro K-WISC score

was 75.6 with a SD of 12.3. Therefore, in this study, cerebral palsy children's IQ

on the K-PTI appeared to be significantly higher than their IQ on the K-WISC (P <

.001). It is assumed that cerebral palsy children's higher IQ on the K-PTI results

from the facts that the K-PTI does not require expressive language and manual

manipulation of objects. Also cerebral palsy children with language and motor

impairments can take the K-PTI without serious problems in responding to the

questions.

The results of this study suggest that the K-PTI is equally and adequately valid

tn terns of measuring the intellectual abilities of both normal and cerebral pansy

children.
