본 연구는 만 2~5세 영·유아의 발달 상태를 객관적으로 평가함과 동시에 발달이 지연된 영·유아를 선별할 수 있는 발달평가도구 문항을 개발하기 위한 예비연구이다. 이를 위해 문헌고찰 및 발달관련 평가도구들을 비교 분석하여 발달지표를 선정하고, 만 2세~5세까지의 영·유아의 언어, 인지, 사회·정서발달영역을 교사관찰에 기초하여 평가할 수 있는 문항을 개발하였다. 연구대상은 대도시, 중소도시, 읍면 소재지 별로 표집 된 만 2세부터 5세까지 총 13개 유아교육기관에 다니는 435명의 영·유아들이며, 본 연구에서 최종 개발된 평가도구의 문항은 총 141문항이다. 평가도구 문항은 언어, 인지, 사회·정서발달영역별로 영·유아의 행동과 언어를 중심으로 교사가 관찰하고, 관찰하기 어려운 문항에 대해서는 단서와 kit를 제시하여 평가할 수 있도록 구성하였다. 개발된 평가도구 문항의 적절성을 알아보기 위하여 내용 타당도와 내적 신뢰도를 살펴본 결과 비교적 양호한 것으로 나타났다. This was a preliminary study to construct a developmental rating scale for understanding children's objective developmental levels and screening developmental disabilities. For this purpose, a developmental indicator was selected by a literature review and comparative analysis of related developmental assessment tests. An assessment scale based on teacher's observations to measure language, recognition, and social-emotional developmental areas was developed. The subjects were 435 young children aged 2 to 5 who lived in both urban and rural areas. A trial test consisted of 141 assessment items in the language, recognition, and social-emotional developmental domains. The developmental scale was evaluated by teachers who observed children's behavior and language, and used clues and kits. Tests on validity and reliability for confirming the appropriateness of the developed assessment scale showed that content was relatively valid and internally consistent.

It can contribute in holistic nursing care for Korean cancer patients and also provide and validate basic data to help oncology nurses measure the outcome of nursing intervention correctly. To develop this instrument, the researchers first estabilished a conceptual framework based on the results of qualitative data analysis and indepth interview method Development of the scale was conducted using a method in which 31 items were assessed by subjects' self report using linear analogue scales. The subjects were 79 D.M. Patients. 103 patients with acute illness, and 91 cancer Patients residing in Busan, Korea. Data were collected during the period from July, 24 to August 14. 2000. This instrument consisted of 31 items with a self report stale. This instrument covered 4 dimensions of cancer patients : 1) Physical wellbeing 2) psychological wellbeing 3) social wellbeing and 4)spiritual wellbeing. Each item had a possible score of 10. The reliability of the scale was tested with Cronbach's alpha. Validity was evaluated by examining the relationships of this scale. Youn's Quality of Life Questionnare scores and the Simple Quality of Life scale. Two separate runs of multiple regression were used to predict scores on the Simple Quality of Life measuremend. Further validation was obtained by examining the correlation between the instrument subscores and Youn's Quality of Life measurement subscore for convergence of this scale. Examination of the discriminant. power of the instrument was done using ANOVA test. The results are summarized as follows : 1.The reliability of the instrument for the quality of life was 0.8321 (Cronbach's alpha.), physical wellbeing dimension 0.6343. Psychological wellbeing dimension 0.6501, spiritual wellbeing dimension 0.5883. 2.This instrument had a high correlation with Youn's Quality of Life measurement(r= 0.636) in cancer Patients, whereas it had a low correlation with Simple Quality of Life measurement(r= 0.455) in cancel patients. In the D.M. patients, the instrument correlated with both the Youn's Quality of Llfe measurement and Simple Quality of life measurement(r=0.313. r= 0.407) and in the acute stage patients. the instrument had no correlation. 3.Multiple regression of individual Items on the Simple Quality of Life scores accounted for 56.8% of the variance in the Simple Quality of Life measurement, whereas, Youn's Quality of Life measurement scores accounts for 31.7%. The correlations collected from the three group had the same patterns of variations but especially the instrument developed in this study had higher disciminant power than that of Youn's Quality of Life Measurement.
