Main Article Content
Low breastfeeding rates have continued to generate public health concerns in Thailand, and a number of nursing intervention programs have been implemented among Thai mothers to enhance the breastfeeding outcomes like practice and duration. Enhancement of self-efficacy in breastfeeding is a substantial method used in the interventions because of the evidence supporting the influence of self-efficacy on breastfeeding behavior and duration. However, the state of evidence relevant to the effects of self-efficacy promoting interventions on breastfeeding outcomes has not yet been examined. The purpose of this integrative review was to determine the methodological and substantive features of the studies of self-efficacy promoting interventions for breastfeeding outcomes published between 2005 and 2015, and listed on Thai databases and CINAHL. Methodological quality was assessed using the Scottish Intercollegiate Guideline Network Methodological Checklist.
The review included 10 eligible studies with acceptable quality. No study with randomized control trial design was found. The reviewed outcomes of the interventions including breastfeeding self-efficacy were found in 7 studies, breastfeeding behavior in 7 studies, and number of mothers giving exclusive breastfeeding in 4 studies. The review indicated the positive effects of self-efficacy promoting interventions on the breastfeeding outcomes. However, clinical heterogeneity was found from diverse sample characteristics, different usual nursing practice across the hospitals, varied dose of the self-efficacy promoting interventions given, and different time of outcomes measurement. Due to insufficient rigorous designs and clinical heterogeneity of the studies reviewed, well-designed clinical trials are needed.
