Background: Fever is the most common symptom in pediatric healthcare. Providing parents with better information on childhood fever management can improve their cognition and home-care abilities. Vietnamese female spouse comprise the largest segment of women who have emigrated from Southeast Asia to Taiwan over the past two decades. After arrival to Taiwan, they have to encounter the events of pregnancy and being a mother. In health care services, language barriers and cultural issues are key healthcare-related barriers to the adaptation of these women to Taiwan society. Purpose: This study assessed the efficacy of using Vietnamese-language fever management education materials in changing the fever management behaviors of Vietnamese mothers living in Taiwan. Methods: This experimental study used a randomly assigned, pre- and post-test approach. A snowball method was used to recruit Vietnamese women living in southern Taiwan with children under 6 years of age. Participants were randomly assigned to experimental (n = 31, Vietnamese-language fever management brochure + VCD) and comparison (n = 30, Chinese-language brochure + VCD) groups. Results: Both groups achieved significantly improvement scores in (fever) information, attitudes, self-efficacy and skills, with improvements significantly higher in the experimental group than the comparison group. Conclusions / Implications for Practice: This study supports that fever management education presented in the recipient's primary language effectively improves recipient fever management knowledge, attitudes, skills, and self-efficacy.
