눈과 손의 협응능력을 측정하기 위한 24문항으로 구성된 지필검사(Eye-Hand Coordination: EHCT)를 개발하여 장애를 가지고 있는 사람과 장애가 없는 사람 155명(8 집단)을 대상으로 신뢰도와 타당도를 검증하였다. EHCT에서 산출되는 9개의 협응점수는 각각 건실한 신뢰도(내적 일관성)를 지닌 것으로 나타났고, 장비를 이용하는 다른 협응능력 측정치들을 준거로 사용한 타당도 검증에서 매우 우수한 심리측정적 속성을 가지는 것으로 나타났다. 더 나아가서, 9개의 협응점수들로 구성된 프로화일은 각기 다른 장애를 가진 집단들을 변별하는 특성이 있음이 확인되었다. 각기 다른 장애를 가진 집단들을 변별하는 프로화일은 본 검사가 향후에 협응과제에서 실패하는 원인에 대한 진단적 도구로 발전될 수 있는 가능성을 가지는 것으로 판단되었다.
A paper-and-pencil test (Eye-Hand Coordination Test: EHCT) to measure eye-hand coordination was developed and administered to 8 groups of 155 disabled and normal subjects. The EHCT consists of 24 items and provides a profile of 9 coordination scores. The internal consistencies of the 9 coordination scores were found to be acceptable. The concurrent validity of the EHCT was examined by means of the relationships of the scores with apparatus measures of coordination and found to be excellent. In addition, the profiles of the coordination scores were found to be able to distinguish people with different disabilities. This last finding suggested the possibility that the EHCT could be developed in the future as a diagnostic instrument to identify the specific underlying problems that cause failures in eye-hand coordination tasks.
