The Impact of an Evidence-based Myth-busting Information Intervention on Maternal Food Allergy Related Quality of Life, Anxiety and Self-efficacy

Children with Food Allergy (FA) are at risk of life threatening reactions. They must carry an emergency medicine kit containing adrenaline auto-injector devices for the immediate treatment of anaphylaxis.

Much research has documented the adverse impact of childhood FA on the food allergy related quality of life (FQoL) of the Carer and the family, along with reported higher levels of anxiety and stress. These adverse impacts are largely driven by the need for Carers to always be "emergency ready". Mothers of food allergic children report higher levels of anxiety compared to the rest of the family, possibly due to mothers commonly being the primary care givers responsible for the preparation of meals, childcare etc.

Carers of newly diagnosed food allergic children, looking for more information about their child's FA are at risk of exposure to myths and misinformation about food allergy. These falsehoods are likely to increase further, Carers Food Allergy-related anxiety.

The investigators wish to survey the frequency with which common myths on FA are believed among mothers prior to their attendance at an allergy clinic. They wish to understand the impact of "myth-busting" information on maternal anxiety or self-efficacy when provided to mothers while awaiting a specialist appointment.

The research question is to determine if the online educational session is effective at decreasing anxiety and improving quality of life in Carers of FA children awaiting a specialist appointment.

Study Overview

• Status: Completed
• Conditions: Food Allergy; Child Allergy
• Intervention / Treatment: Behavioral: "Myth busting" information leaflet

Detailed Description

Carers of food allergic children report that their information needs are greatest at the beginning of their journey when their child first experiences a food allergic reaction. Unfortunately, wait times to attend specialist paediatric allergy clinics can be lengthy. Thus, families can experience a prolonged time-gap between the initial allergic reaction and accessing diagnostic testing and benefitting from multi-disciplinary support and education. Furthermore, carers report often contradictory advice from non-specialist Healthcare Professionals (HCPs). This in turn encourages carers to look for information online with many using search engines unless guided to official food allergy websites by HCPs. Not all online information is correct, or evidence based. Often information provided suggests that certain FA children are at greater risk of anaphylaxis and mortality. This in turn increases anxiety amongst carers and impairs their quality of life.

The purpose of this study is to develop an effective intervention that improves maternal FA related quality of life, anxiety, and self-efficacy prior to attending their child's first paediatric allergy clinic appointment. A randomized control trial will be performed comparing quality of life, anxiety and self efficacy in carers who receive the intervention versus those that do not. Participants will be randomized into 2 groups. All volunteers, from both groups, will complete questionnaires online using only a study identifier number. This will ensure anonymity throughout the study. The only personal information that will be asked is the carer's age group, whether they are a mother or father, their child's age and gender and whether they have any other allergies. Group 1 will be sent a written patient information leaflet displaying ten food allergy myths with the myth-busting evidence-based information clearly stated. Two weeks following the online educational session, Groups 1 and 2 will again complete the online questionnaires.

The outcomes are health related quality of life and levels of anxiety. It is hoped that the findings will positively support Carers, children and their families
