Adolescent mothers may lack confidence in their ability to breastfeed their infants.
Adolescent mothers with low breastfeeding self-efficacy, may not have been successful with exclusive breastfeeding. The purpose of this quasi-experimental research was to examine the effect of self-efficacy enhancement on exclusive breastfeeding at 6 weeks among adolescent mothers. The subjects consisted of 44 adolescent mothers admitted into the postpartum ward at Banpong Hospital in Ratchaburi from March to July 2016. They were selected using the inclusion criteria and equally divided into the control and experimental groups with twenty-two in each group, as a matched pair design. The research instruments consisted of 2 parts. Part 1 included the breastfeeding self-efficacy enhancement plan, a video presenting a symbolic model, a breastfeeding flip chart, a comic chat used instead of words, and the book "Hai Look Kin Nom Kra Phong Nae Jai Reu” (Are you sure you want to give your baby formula milk). Part II included a breastfeeding self-efficacy questionnaire and the exclusive breastfeeding questionnaire. Data were analyzed using descriptive statistics and the Chi-square test.

Results of the study revealed that:

The adolescent mothers in experimental group had significantly higher exclusive breastfeeding rate at 6 weeks than that of the control group (p < .001)
