The purpose of this study were to find out the practical way to enlarged child-raising knowledge and to enhance their satisfaction with out-patient care by evaluating how effectively the education is done by nurses for mothers with ill-child and how their satisfaction with out-patient care changed. This study was designed as a Nonequivalent Control Group study. The subjects studied were consisted of the experimental and control group. Each consisted of 50 mothers with ill-child in pediatric department at one university hospital in Seoul. The period of this study is from May 20, 1996 to J one 28, 1996. The first data were collected from both of experimental and control groups in which mothers with ill-child come to the hospital for the first time. After this being done, the experimental group had been educated by the planned program and then the second data were collected from them. On the contrary, as for the control group, there had been no education and the second data were col looted on the same method. The data analysis was done by SPSS program. The results of this study are as follow, 1 The child-raising knowledge level of mothers with education was higher than that of with no education. (t=18.84, df=49, p=0.000) 2. The satisfaction with out-patient care level of mothers with education was higher than that of no education. (t=10.51, df=49, p=0.000) Based on these results, I suggest as follow, 1. The research on the patients and their family should be made not only in pediatric department, but in every out-patient department. 2. For more effective education, it is required for all out-patient nurses to research the education demand of patients and their family. 3. To increase the effect of education, there must be the consultation room in out-patient department. 4. The meetings with the mothers with ill-child of the same illness have to be established and periodical education must be executed. 5. Audio-visual education programs like video tapes are needed to make use of waiting time for the medical treatment. 6. On-line consulting programs are needed.
