Twenty two of the theses were doctoral ones from 6 nursing colleges. There were 16 theses only by 1980, yet the number increased to 93 in 1980`s. The number of theses sharply increased in 1990`s, when researchers adopted various scopes and methods of research. Accordingly, the number(113) of these published in recent 5 years was greater than the number(108) published between 1962 and 1990. 2. Surveys(42.5%) and correlational studies(34.4%) were most prevalent and these research designs were mainly conducted before 1980. Quasi-experimental design was adopted after 1981 and it has been conducted more oftentimes in recent years. Qualitative study was reported after 1986 and the rate of thesis using this design increased rapidly between 1991 and 1995. 3. As for the subjects, healthy people were greatest, which were followed by patients, nurses, families of patients, and families of healthy people, in that sequence. According to the developmental stage of the subject, adults took most, followed by adolescents, the school-aged and aged. 4.
