The primary purpose of this study is to develop a quality of life scale for adults with developmental disabilities and to test its validity and reliability. For this purpose, the authors generated a initial item pool composed of 62 items based on the conceptual model of Felce and Perry (1995). The initial items were evaluated by three reviewers, and then the items were revised based on their feedbacks. Utilizing a survey questionnaire including the scale items, data on 430 adults with developmental disabilities were collected in collaboration with 33 social welfare agencies and residential facilities for people with disabilities. Through descriptive analysis, correlation analysis, and relevant theories, the qualities of each item were examined, and then the best 20 items were selected. Cronbach's ${\alpha}$ for the final scale was .87. The results of confirmatory factor analysis showed that the 5-factor model fitted the data reasonably well, In addition, criterion validity of each subfactor of the scale was successfully established, employing t-test, one-way ANOVA, and correlation analysis. In discussion, implications and limitations of this study were examined.

This study analyzes the effects between stock returns and interest rate spread, difference between long-term and short-term interest rate through the polynomial linear regression analysis. The existing research concentrated on the business forecast through the interest rate spread focusing on the US market. The previous studies verified the interest rate spread based on the leading indicators of business forecast by moderating the period of long-term/short-term interest rates and analyzing the degree of leading. After the 7th reform of composite indices of business indicators in Korea of 2006, the interest rate spread was included in the items of composing the business leading indicators, which is utilized till today. Nevertheless, there are a few research on stock returns of each industry and interest rate spread in domestic stock market. Therefore, this study analyzed the stock returns of each industry and interest rate spread targeting Korean stock market. This study selected the long-term/short-term interest rates with high causality through the regression analysis, and then understood the correlations with each leading period and industry. To overcome the limitation of the simple linear regression analysis, polynomial linear regression analysis is used, which raised explanatory power. As a result, the high causality was verified when using differences between returns of corporate bond(AA-) without guarantee for three years by leading six months and call rate returns as interest rate spread. In addition, analyzing the stock returns of each industry, the relation between the relevant interest rate spread and returns of the automobile industry was the closest. This study is significant in the aspect of verifying the causality of interest rate spread, business forecast, and stock returns in Korea. Even though it could be limited to forecast the stock price by using only the interest rate spread, it would be working as a strong factor when it is properly utilized with other various factors.
