Navigating through life with a peanut allergy is challenging for children and requires developmentally appropriate self-management or children could experience unfavorable allergic reactions. This research study presents self-efficacy as an important construct of peanut allergy management in childhood. This study aimed to illuminate the extent that Bandura's four sources of self-efficacy contribute to the development of self-efficacy in children ages 7 to 10 with a peanut allergy in educational settings. The phenomenological study was motivated by three research questions: (1) What are peanut-allergic children's socioemotional experiences with daily routines in educational settings? (2) From the perspective of a peanut-allergic child, aged 7 to 10, how do Bandura's four sources of self-efficacy influence their development of self-efficacy as they experience daily routines in educational settings? (3) Based on the experiences described by a peanut-allergic child aged 7 to 10, what other self-efficacy sources, if any, influenced their development of self-efficacy in educational settings? The children participated in a draw-and-tell exercise, a peanut allergy self-efficacy scale and a child-centered interview, which revealed a snapshot into their lived experiences with a peanut allergy. This study found that 92.77% of children with peanut allergies recorded fairly-confident to highly confident self-efficacy when responding to their self-efficacy in school routines. The participants in this study have self-efficacy skills that give them the ability to develop and engage in strategies that allow them to begin to self-manage their peanut allergy. The variety of self-management strategies give an understanding of the vigilance and awareness that children with peanut allergies encounter in daily routines when food is present. Awareness of the environment and careful observance of the actions of others is critical when managing a peanut allergy. This study advances our understanding of how peanut-allergic children ages 7 to 10 are becoming advocates for themselves and their peanut allergy. A recommendation to explore the self-efficacy perspectives of children as young as age 4 might uncover the inaugural feelings of the phenomena. With peanut allergies ranking as the most common cause of food allergy deaths in the US, further self-efficacy research from the perspective of children is warranted.
