A parent's ability to confidently manage a child's food allergy (i.e. food allergy response capability) is considered instrumental toward treating this disorder; however, little is known regarding this measure and associated factors. A questionnaire survey among 280 qualified participants identified the greatest food allergy response capability as "spousal collaboration", followed by "elimination diet capacity", "gathering information from medical professionals", "knowledge about food allergies", and "stress coping". These capabilities were associated with maternal and household health status, food items eliminated and their number, anaphylaxis experience, and type of medical facility used. This measure represented a predictor of maternal quality of life and health status, household health status, and overall life stress (not related to childrearing). Thus, to improve food allergy response capability, multidisciplinary cooperation and support are required from professionals, such as physicians, nurses, nutritionists, and clinical psychologists. Nurses in particular must take an interest in the situations these mothers face and in their emotions; elicit their power to cope with stress; provide knowledge about food allergies; provide individualized, specific information about elimination diets; and conduct interventions to enable spousal cooperation.
