다국어 초록 (Multilingual Abstract)

As a number of various environmental problems have been widely exposed to the public particularly through the mass media in recent years, they have become growing public concern as well as one of important social issues. In accordance with this new social phenomenon in Korea, several attempts have been made to measure environmental consiciousness of the public by the use of questionnaire surveys. These survey researches have, however, tended to largely ignore reliability analysis-a very important criterion in assessing the stability, consistency, or accuracy of measured results. Consequently, we are not confident that their results and conclusions are reliable. With respect to this reliability problem, this paper stresses the importance of reliability analysis in questionnaire survey researches by explaining the concept and theoretical background of reliability, analyzed reliability of an actual questionnaire survey designed to measure public consciousness of environment, and finally presents major methods of improving reliability. Our reliability analysis of a sample questionnaire survey gnerally revealed low reliability. This means that measured scores obtained from that questionnaire contain a significant portion of error scores resulting from various sources of random errors and a measuring instrument is not highly reliable. It is thus necessary to recompose, modify and remedy a sample questionnaire to improve reliability. While reliability is not the most important facet of measurement, it is still extremely important. Reliability analysis is designed to maximize the variance of the individual true differences and minimize the error variance. Without it, no good scientific results can be produced. Reliability is a necessary condition of the value of research results and their interpretation.
