PURPOSE: The purpose of this study was to explore the effects of a Taegyo program on parents-fetal attachment and parenthood in first pregnancy couples (mothers and spouses). METHODS: The research design was a nonequivalent control group pretest-posttest experiment. Study participants were 52 first pregnancy couples visiting two medium-scale obstetrics and gynecology clinics located in Gwangju. A total of 52 couples were assigned to the experimental group (25 couples) and the control group (27 couples). The experimental couples were provided with a Taegyo program for 4 weeks. Data were analyzed by chi square test, t-test, and ANCOVA using the SPSS program. RESULTS: Post-treatment maternal-fetal attachment, paternal-fetal attachment and motherhood significantly increased in the experimental group as compared to the control group, but post-treatment fatherhood, anxiety, blood pressure and pulse of participants in the experimental group showed no significant difference from those in the control group. CONCLUSION: From these results, it is suggested that the Taegyo program has beneficial effects in enhancing parent-fetal attachment and motherhood in first pregnancy couples. Therefore, a Taegyo program can be recommended as a nursing intervention program for first pregnancy couples.
