초록
연구목적: 본 연구의 목적은 직업능력평가를 위한 시각장애인용 음성형 인지기능검사를 개발하고 타당화하는데 있다. 연구방법: 검사의 측정영역은 음성으로 구현하기 어려운 공간능력을 제외한 언어, 수리 및 추리영역역이다. 예비검사를 통해 응답시간과 문항변별도, 난이도를 고려하여 영역별 22문항, 총 66문항을 본검사에 사용하였다. 화면 낭독 프로그램은 보이스위드를 사용하였다. 시각장애인 106명(남=72, 여=34; 전맹=55. 저시력=51)이 본검사에 참여하였다. 타당도 검증을 위해 K-WAIS-IV를 실시하였다. K-WAIS-IV의 어휘, 수리, 숫자, 공통성(추리)영역을 측정하였다. 연구결과: 내적신뢰도 분석 결과, 모든 문항에 대한 전체 신뢰도는 .94였고 영역별 신뢰도는 .82～.89 사이로 양호하였다. 동시타당도 분석 결과 총점 간의 상관은 .73, 동일 영역 간에는 .63 ～.71 사이의 타당도를 보였다. 시사점: 본 연구에서 개발된 검사는 실시와 채점의 간편성이 있고 양호한 신뢰도와 타당도를 보여 규준연구결과가 추가된다면 현장에서 쉽게 사용될 수 있을 것으로 보인다.
Abstract
Objectives: The purpose of this study was to develop and validate a voice-type cognitive function test for the visually impaired for Vocational Ability Assessment. Methods: The measurement areas of the test were verbal, math, and reasoning, except for spatial ability, which is difficult to implement through voice. A total of 66 items, 22 items per area, were used in the main test, considering response time, item discrimination, and item difficulty through preliminary testing. The screen reading program used Voice With. 106 visually impaired individuals (male=72, female=34; total blind=55, low vision=51) participated in the test. The K-WAIS-IV was used in this study to verify concurrent validity. The K-WAIS-IV measures vocabulary, arithmetic, digit span and similarity (reasoning) domains. Results: The internal reliability analysis showed that the overall reliability for all items was .94, and the item-specific reliability was good, ranging from .82-.89. Concurrent validity analysis showed a correlation of .73 between total scores of the two tests and validity between the same domains of thee two tests ranging from .63 to .71. Implications: The test developed in this study is easy to administer and score, and shows good reliability and validity, so it can be easily used in the field if research on norms is conducted.
