Translating and Validating the Vietnamese Version of the Health Sciences Evidence-Based Practice Questionnaire.

No validated instrument is available for assessing the evidence-based practice capacity of Vietnamese health professionals. This study aimed to translate and validate the Health Sciences Evidence-Based Practice questionnaire (HS-EBP) from English to Vietnamese and ascertain its psychometric properties. Data were collected from two obstetric hospitals in Vietnam. Participants: A total of 343 midwives were randomly selected. The HS-EBP questionnaire was translated by a group of bilingual experts into Vietnamese (HS-EBP-V). Content validity was assessed by two experts. Internal consistency and test-retest reliabilities were assessed using Cronbach's α and intraclass correlation (ICC), respectively. Construct validity was assessed using the contrasted groups approach. As a result, the content validity index of the HS-EBP-V reached 1.0. For the individual subscales, Cronbach's α was 0.92-0.97 and ICC was between 0.45 and 0.66. The validity of the contrasted-groups approach showed discrimination by a significant difference in the subscale scores among diploma holders compared with bachelor's degree holders (p < 0.001). The validation of the HS-EBP questionnaire indicated satisfactory psychometric properties. The results indicate that the HS-EBP is a reliable and valid instrument which assesses the competencies of as well as facilitators of and barriers to the five steps of EBP among midwives. The HS-EBP-V was deemed a reliable and validated tool for assessing the competency and application of EBP among Vietnamese healthcare professionals.

Breastfeeding self-efficacy and related factors in postpartum Vietnamese women.

BACKGROUND: Breastfeeding self-efficacy refers to a mother's confidence about her ability to breastfeed, which has been found to shape her choice about whether or not to do so. It depends on social and psychological factors and has not previously been studied in postpartum Vietnamese women. PURPOSE: The purpose of this study was to explore factors related to breastfeeding self-efficacy and its predictors among postpartum Vietnamese women. METHODS: This cross-sectional study was conducted on 164 postpartum women in Tu Du hospital in Vietnam from August to September 2017. The study used the Breastfeeding Self-Efficiency Scale (BSES), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Edinburgh Postnatal Depression Scale (EPDS) to explore factors affecting breastfeeding selfefficacy. Independent t-test, ANOVA, Pearson's correlation coefficient, and hierarchical linear regression were used to determine the relationship between independent variables and the dependent variable. RESULTS: Breastfeeding self-efficacy was related to mothers' age, mother's occupation, previous breastfeeding experience, mode of delivery, skin-to-skin contact with the baby, and extent of breastfeeding in the hospital. It was also positively correlated with social support and was significantly lower in women with more postpartum depression. Independent variables predicted 36.8% of breastfeeding self-efficacy in the hierarchical linear regression. CONCLUSION: Strategies to foster breastfeeding self-efficacy should focus on decreasing the incidence of postpartum depression and promoting social support for breastfeeding. Health care providers should screen for and pay close attention to signs of postpartum depression. Moreover, health care providers should offer adequate support tailored to the mother's needs and involve her social network in breastfeeding education.
