PURPOSE: This study is attempts to clarify the effect of infant massage for the promotion of primipara's mother-infant interaction METHOD: The term for collecting data for experimental group ranged from April 25, 2001 to June 5, 2001. The infants for this group were sampled among normal mother-infant from one postpartum care center located in J city. The term for collecting data for control group ranged from June 10, 2001 to August 3, 2001. The infants for this group were sampled among normal mothers infant from 1 general hospital, 1 university hospital and 1 postpartum care center located in J city. The experiment was implemented giving primipara education about massage based on protocol for infant massage provided by Johnson and Johnson Korea and they received 10 days of education, 10 minutes a day (from 10 to 11 a.m) In the post test, we videotaped both the control group and the experimental group visiting their homes 4 weeks after delivery to observe mother-infant play interaction. Data analysis was done using SAS and the homogeneity between general properties owned by both control group and experimental group and mother's perception scale for children was verified through x2-test. Mother-infant play interaction with both control group and experimental group was analyzed through t-test in the experiment. And analysis of mother-infant interaction points based on general properties was made using ANOVA and t-test. RESULT: Hypothesis that mother-infant play interaction with primipara who gave her infant a massage will be more active than that of the primipara who didn't was verified (t=-4.27, p=.0001). And the points in each item, points in each item were estimated as follows. Mother behavioral items (t=-4.96, p=.0001), infant behavioral item (t=-0.36, p=.71), mother-infant interaction reciprocity (t=-2.64, p=.01). CONCLUSION: An infant massage program can contribute to promoting the Mother-Infant Play Interaction positively.
