탈 현대인의 질적 삶을 제고하기 위하여 자기 결정 능력의 신장은 필수 요소일 것이다. 탈 현대는 수많은 선택적 상황에 놓여 있기 때문에 수사로 결정해야만 한다. 특히 발달지체인은 이런 능력이 부족하여 조직적 훈련을 필요로 하고 있다. 이에 부응하기 위한 자기 결정 능력 검사의 표준화 연구는 그 필요성이 인정된다. 자기결정능력검사는 자율성, 자기규칙, 심리적 역량과 자아실현으로 구성되며, 전국에서 710명을 표집하여 검사를 실시한 결과 신뢰도 .91로 높았고, 내용타당도와 구인타당도 역시 양호하였다. 하위검사별 양호도에서도 검사로서 무리가 없었다. 이 연구에서 자기결정능력지수(SDQ)는 표준 점수로 환산하였으며 상대적 위치를 확인하게 하였다.

The purpose of this study was to investigate the definitional structure of self-determination abilities and to standardize the Self-Determination Scale for developmental disability adolescents. Using the responses of 710 adolescents(male 363, female 347), reliability, validity, and other related statistical analyses were done. The findings from the study were as follows; 1. The Self- Determination abilities is an ability to find the meaning of life and control self spontaneously; is an ability to raise the attitude, personality, and ability to control life, to interact with environment appropriately, and to get free and self-reliant function; and is an ability to recognize the value of self and to select and determine something with subjectivity. Self-determination behaviors consist of four elements: autonomous behavior based on self-protection and self-direction; self-regulated behavior to spontaneously determine how to behavior and to evaluate achievements and outcomes; psychological empowerment including efficacy, control attribution. motivation; and self-realization behavior to utilize one`s strengths and weaknesses using one`s own comprehensive knowledge in accordance with what is reasonable. 2. Psychometrical properties of the Scale including reliability(Cronbach α =.95) and construct validity tested using developmental change were appropriate. In conclusion, the Scale seems an appropriate tool to measure developmental disability adolescents` self-determination behaviors.
