Purpose: The study was done to investigate effects of a parent empowerment program using MBTI (Myers-Brigs Type Indicator) on self-esteem, parent-child communication, and parenting sense of competence in mothers of elementary school students. Methods: Research design was a quasi-experimental research with pre- and post-test. Participants were 26 mothers recruited from mothers of elementary school students. The program was provided to the experimental group for 60 minute sessions once a week for 8 weeks. Data were analyzed using Fisher's exact probability test, x² test, and t-test with SPSS/WIN 12.0 program. Results: The first hypothesis was verified as the score for self-esteem in the experimental group was significantly higher than the control group (t=3.14 p<.001). The third hypothesis was verified as the score for parenting sense of competence in the experimental group was significantly higher than the control group (t=2.58 p<.017). Conclusion: These results indicate that the parent empowerment program applying MBTI enhances self-esteem and parenting sense of competence in mothers of elementary school children. Therefore, this program is an appropriate strategy for community mental health nurses to use to improve parent empowerment.
