Abstract
Food allergy (FA) is potentially severe and requires intensive education to master allergen avoidance and emergency care. There is evidence suggesting the need for a comprehensive curriculum for food allergic families. This paper describes the results of focus groups conducted to guide the development of a curriculum for parents of food allergic children. The focus groups were conducted using standard methodology with experienced parents of food allergic children. Participants were parents (n=36) with experience managing FA recruited from allergy clinics at two academic centers.
Topics identified by parents as key for successful management included as expected: 1) early signs/symptoms, 2) “cross-contamination”, 3) label-reading, 4) self-injectable epinephrine; and 5) becoming a teacher and advocate. Participants also recommended developing a “one pageroad map” to the information, and to provide the information early and be timed according to developmental stages/needs. Suggested first points for curriculum dissemination were emergency rooms, obstetrician and pediatrician offices. Participants also recommended targeting pediatricians, emergency physicians, school personnel, and the community-at-large in educational efforts. Parents often sought FA information from non-medical sources such as the Internet and support groups. These resources were also accessed to find ways to cope with stress. Paradoxically, difficulties gaining access to resources and uncertainty regarding reliability of the information added to the stress experience. Based on reports from experienced parents of food allergic children, newly diagnosed parents could benefit from a comprehensive FA management curriculum. Improving access to clear and concise educational materials would likely reduce stress/anxiety and improve quality of life.

INTRODUCTION
There is evidence that food allergy is common and increasing, particularly among infants and children,(1) which means that healthcare professionals are being faced with an increasing burden to care for children with food allergies. Currently, the only way to manage food allergy is through a food allergen avoidance diet and medical management of symptoms. Dietary avoidance is complex and requires thorough education regarding cross-contamination, label reading, and food substitution. This education must often be provided by pediatricians and other primary health care professionals providing healthcare for these children. Previous studies have shown that parents caring for children with food allergies often do not know how to appropriately use emergency medications(2) and experience accidental exposures to foods caused by various errors in purchasing and preparing meals for their children(3). Additionally, assessments of physician’s food allergy knowledge shows deficits in the same areas attributable to errors made by families(2, 4). In general, primary care providers may not have the tools needed to educate families of food-allergic children.
We selected focus groups as the first step in the curriculum development process because it is an empirically-based methodology(5) successfully used to identify the educational needs of patients with atopic dermatitis(6), asthma (7–9), and food allergy(10,11). Our main objective was to investigate the parental perspective regarding their food allergy educational needs. This information was then to be used to design a comprehensive food allergy curriculum for parents. A secondary goal was to gather recommendations for effective dissemination of the curriculum to parents of food allergic children. Unsolicited information regarding psychological/behavioral skills and resources sought by parents to effectively cope with the demands of food allergy management was a recurrent theme and is incorporated in this analysis.
METHODS
We conducted four focus groups using a semi-structured interview format following standard methodology(12). Twelve open-ended questions were prepared to elicit responses pertinent to the study goals (Table 1). Questions were developed by a multidisciplinary team of food allergy experts including a dietitian (LC), two nurses (SN, SC), two allergists (SHS, SMJ) and a psychologist (PAV). We opened the discussion with the question what information you think helped you the most to manage your child’s food allergies? Then questions listed in Table 1 were used to prompt and re-direct the discussion.

The study was approved by the Institutional Review Boards of the University of Arkansas for Medical Sciences (UAMS) and Mount Sinai School of Medicine. A convenience sample of parents of children ≥ 1 year old with ≥ 1 year of experience managing food allergy who were not enrolled in the observational study of the Consortium of Food Allergy Research (http://www.cofargroup.org) were invited to participate by the clinic dietitian at Arkansas Children’s Hospital and the clinic nurse at the Jaffe Food Allergy Institute in NY. Participating parents were consented and asked to fill out a brief demographic questionnaire. They then participated in a focus group session that lasted 60 – 90 minutes.
The focus group sessions were conducted in conference rooms at each institution by the same moderator (PV) and assistant moderator (DW) who took field notes. Drinks and snacks were served at an informal social gathering preceding the focus group sessions. Participants were compensated $40 for their time. All focus groups took place within a 3-month period. The sessions were audio-taped, transcribed verbatim, and coded using qualitative analytic techniques. Preliminary analysis began in a debriefing session between the moderator and assistant moderator immediately after each session.
Transcripts were analyzed by hand independently by two coders (MK and PV); no software was used. Coding consisted of systematically reading the transcripts, grouping similar responses, and extracting themes. After reading the transcripts several times a preliminary outline of the codes was developed. Coding categories were discussed and agreed upon. Transcripts were re-read and core themes were further analyzed and subcategories emerged. This process was repeated until the final coding system was agreed upon and reviewed by all authors. Recurrent themes emerged during the discussions across questions (Table 1); therefore the results are presented as core themes and subcategories rather than as direct responses to each question. Samples of representative quotes from the parents were selected from among many similar comments to illustrate each theme and subcategory. Discrepancies were discussed and resolved, PV was responsible for all final coding decisions.
RESULTS
Thirty-six parents of children with food allergy (89% mothers) with a median of 5.25 years of experience managing food allergies (range, 1–19 yrs) participated in four focus groups, two in each city --Little Rock, AR and New York, NY. Only two husband and wife couples participated in the focus groups, one in NY and one in Arkansas. Detailed demographic information is presented in Table 2.

Three core themes and subcategories emerged from all four focus groups. Results are presented as core themes and subcategories rather than as direct responses to the questions: 1) curriculum content, 2) recommendations regarding characteristics of the curriculum, and 3) psychological/behavioral issues associated with food allergy management.
Curriculum Content
Four subcategories emerged regarding the curriculum content. Samples of representative quotes from the parents are presented in Table 3

Understanding Early Signs/Symptoms
For most parents, the diagnosis of food allergy was not immediate after the first food allergic event. Both parents and primary care providers struggled with the diagnosis, and in many cases it was not until a severe reaction that the food allergy diagnosis was suspected and later confirmed. Parents agreed that understanding the pattern of symptoms for food allergy early on would have helped them identify the problem and seek out specialized care earlier e.g., realize that eczema is not normal. They recommended designing handouts with the risk factors and early signs and symptoms of food allergy using “a grid” to allow parents to see the pattern of symptoms and expedite an early diagnosis. Parents recommended distributing these handouts at multiple settings particularly for expecting parents (see distribution mode below).
Understanding Issues of Allergen “Cross-Contamination”
Most parents acknowledged making multiple mistakes before being able to implement the dietary restrictions recommended by their healthcare provider. Key to the successful implementation was understanding the concept of “cross-contamination” (when an allergen contaminates a safe food during processing/handling) and the fact that dietary avoidance meant avoidance of the “protein” in the offending food and not just the specific offending food (e.g., avoiding “milk” includes not only liquid milk but also cheese, butter, ice cream, and products containing milk proteins (casein, whey) such as baked goods (e.g. I would lift the cheese off the pizza and keep feeding her pizza).
Understanding Label Reading
Parents were very cognizant of the importance of label reading for appropriate food preparation. Mastering reading labels provided parents some sense of control and allowed them to shop for groceries with some confidence. Parent indicated that learning to read labels is a first step, but doing it consistently is a critical point to prevent mistakes.
Understanding use of Self-Injectable Epinephrine
Most families in the focus groups have used epinephrine injections suggesting personal experience with at least one anaphylactic reaction. Parents recommended the inclusion of information covering the need for this skill and the fact that self-administered epinephrine is safe and has very few contraindications.
Characteristics of the Curriculum
Three related subcategories emerged with regard to parents’ recommendations of the characteristics of the curriculum: timing, complexity and length, and distribution mode (Table 4)

Timing
Participants suggested that the curriculum should cover different stages of food allergy management (e.g., early identification, diagnosis & management) and child development (e.g., infancy, early childhood, adolescence). Participants stressed the importance of recognizing that as the families progress in the process of food allergy management, their needs change (e.g., from symptom identification to food preparation), and their educational needs also change. On the other hand, as children developed, the needs and challenges that families encounter also change (e.g., going to daycare, summer camp, dating, etc). Finally, parents also recommended extending this education to pediatricians, emergency department physicians, school personnel, and the community at-large.
Length and complexity
Participants had specific recommendations concerning the complexity and length of the educational materials. Most parents reported being overwhelmed by the prospect of having to manage severe food allergies. Some were overwhelmed by the amount of information they had to digest after the diagnosis, often without clear educational materials and/or guidance. Although the internet was mentioned often as a great resource of information, the difficulty and amount of time spent sorting out “the good” from “the bad” was also mentioned as a source of stress. So, the key recommendations included preparing a curriculum with “layers” of information using simple language that parents could access when their needs arise and including a “one page-road map” summarizing the steps to successfully manage food allergy.
Educational Formats and Modes of Distribution
Regarding the dissemination of the curriculum, parents recommended distributing the information in multiple settings such as medical offices (e.g., obstetricians/gynecologists, pediatric, and emergency departments) and hospitals at parents’ training and meetings (e.g., CPR training, childbirth classes, La Leche League meetings). Acknowledging differences in learning styles and resources, parents suggested that materials should be available in a variety of formats: printed, video-based, and web-based. Finally, to create confidence among families, parents also recommended having a federal agency or a well know medical institution endorsing the curriculum.
Psychological/behavioral Issues
Becoming Teacher and Advocate
In addition to specific food allergy information, parents reported also benefiting from specific behavioral strategies and resources to effectively manage food allergy (Table 5). Parents reported that learning to be advocates for their children was critical for successful food allergy management. Parents described the role they are forced to play in educating others around them about food allergy and food allergy management.

Coping
Several coping strategies also emerged as part of the core of psychological issues associated with food allergy management. Particularly important was having a support group and/or “buddy system” to help with the ongoing learning to effectively manage food allergies and the stress associated with managing food allergy. Parents emphasized how ongoing learning empowered them, and made them advocates for their children. Parents often sought food allergy information from non-medical resources such as the Internet and support groups. These resources were also accessed to search for ways to cope with stress. Paradoxically, difficulties accessing these resources and uncertainty regarding reliability of the information sometimes added to the stress experience.
Framing
Parents described two general outlooks or “framing” approaches of their experience managing food allergy. Although, both strategies were mentioned in all groups there was a different emphasis among the different focus groups by region: Parents’ “framing” [i.e., a decision maker’s perception of a problem, the outcomes, and the consequence(13)] of the issues associated with food allergy management seemed to have an impact on the level of stress reported. A positive framing as a coping strategy was a core theme that emerged strongly among the parents in Arkansas and was confirmed by some parents in New York. Positive framing was characterized by statements such as “I think it’s made us better parents… with my boy having his allergies I find myself caring more about what’s going on in his environment.” On the other hand, a more negative framing and hyper-vigilance (i.e., an ever-present sense that you must watch-out or you might fall victim to harm) was a coping strategy strongly expressed by parents in the New York focus groups and with less intensity mentioned by parents in Arkansas. These parents reported a great sense of loss. They described going to great lengths to provide their children with a “normal” childhood (e.g., he was going to be able to purchase food outside of my house and feel like a halfway normal kid so if I had to spend 50 hours doing it, I was going to do it). This sense of loss and hyper-vigilance seemed associated with high stress levels. Hyper-vigilant parents were very much aware of the reaction of others toward them (e.g., the insane looks I got).
DISCUSSION
Based on evidence that effective health communication can empower people to make informed health-related decisions and improve their quality of life, and parents’ recommendations, we concluded that parents of newly diagnosed children could benefit from a comprehensive food allergy management curriculum. The curriculum should include a “one page-road map” of the information and skills necessary to successfully manage food allergy including: food allergy signs and symptoms, treatment, use of self-injectable epinephrine, food avoidance, label reading, cross-contamination, and guidance on management outside the home. Recommendations regarding strategies to cope with stress and improve quality of life should also be included. The information should be user-friendly, succinct, using lay terms. Consistent with previous findings (10), parents reported experiencing different phases in their need for information: when first symptoms appeared, when first diagnosed, when they start facing managing issues at follow-up, and at new events and milestones. Thus, the curriculum should be tailored to these different “stages” of food allergy management and child development (e.g., risk assessment for expecting parents, newly diagnosed, going to school, etc.). A curriculum forewarning parents of these stages of change, as well as the resources necessary for such transitions should help families prevent errors. Each step to be mastered should have succinct information and use lay terms with appropriate links to more in-depth information, if needed. Also consistent with Hu (10), was the preference for information in a variety of formats. To fit different needs and learning styles participants recommended using video/DVDs and printed formats as well as a web-based format for distribution. Data from the National Telecommunication and Information Administration (NTIA) and the Pew Center support the use of the internet as an efficient strategy for distribution of educational materials. In 2010, the NTIA found that approximately 70% of the US population access the internet regularly either from home or work. (14) On the other hand, the Pew Center found that 80% of American internet users, or some 113 million adults, have searched for information on at least one of seventeen health topics and 53% of health seekers report that the most recent health information session had an impact on a health-related decision (15). Compared with traditional methods of health education, web-based formats appeal to patients with different learning styles and educational backgrounds, are easy to use, video clips do not need additional expensive hardware, quality patient hand-outs containing text and graphics can be generated and keep up-to-date inexpensively compared to printed materials and DVDs, and can be tailored to different groups (e.g., pediatricians, nurses, parents) (16–18). Information and links to the web-based curriculum, including materials about early diagnosis, could be made available at different settings such as medical offices (e.g., obstetric/gynecologic, pediatric, and emergency departments) and hospitals (e.g., during birthing classes and CPR training). Although these reflect the parental suggestions, the scope and impact of such materials would need to be investigated. To inspire confidence, the curriculum should be endorsed by highly respected academic and/or research institutions.
Although the study was not designed to inquire about the psychological factors associated with food allergy, the distress experienced by parents due to the lack of reliable food allergy information emerged as a core theme and was thus included in the results. To cope with the stress and anxiety resulting from food allergy management, parents sought multiple pathways including seeking social support and following a pro-active, assertive style to seek-out care and information, advocate for their children, and teach others. Parents described two general outlooks or “framing” approaches of the food allergy experience that seemed to be related to their coping strategies and levels of stress. A hyper-vigilant framework seems to be associated with a sense of loss and high stress levels; while a more optimistic-positive outlook seems to help achieve a sense of normalcy and reduced stress. These different framing styles might be the result of cultural differences due to life-style demands (NY vs. Little Rock) or other factors such as aversion to risk, personality, or the families’ traumatic experiences regarding food allergic events (19). Similarly, Cornelisse-Vermaat and colleagues (20) found differences in the problem solving strategies and levels of frustration reported by patients with food allergies of Greek and Dutch origin.
Food allergy may have a significant impact on quality of life(21–24). Extreme and/or prolonged exposure to negative emotions can trigger some psychological problems (25). Several characteristics of food allergy might elicit high levels of emotional distress, anxiety, and burden for parents. The most critical is the possibility of a fatal anaphylactic reaction to the offending food. Other challenges for families managing food allergies include the ambiguity of food allergy symptoms, the pervasiveness of some food items in the food supply (e.g., milk, egg) and the food-centric nature of most cultures. Despite families efforts to avoid the offending food, unintentional ingestions frequently occur(26). There is evidence showing that caregivers of food allergic children suffer some degree of anxiety in response to the potential for severe reactions and the perceived lack of control in some situations(21, 24). Fear of exposure after a food allergy diagnosis may lead to severe social isolation of the child(23). On the other hand, clinicians might contribute to the psychological distress associated with food allergy by implementing aggressive, yet necessary, dietary changes, as well as providing extensive, potentially frightening, counseling regarding risks associated with unintentional ingestion of the offending food allergens(27). Research has shown the benefit of eliciting positive emotions as a therapeutic intervention to reduce/prevent psychological problems (28). In particular, hope and optimism have been found to buffer against depression (29). Additionally, there is also evidence that the “framing” (i.e., emphasizing the benefits of taking action or the costs of not taking action) of a health message might influence people’s health behavior.(30) Research exploring successful food allergy management behaviors and the process that shapes them is very limited. Thus, research assessing the psychological factors mediating the families’ coping strategies and their quality of life as well as the strategic use of framed messages to promote appropriate food allergy management without high levels of stress among parents and their children is warranted.
The purpose of this study was to investigate the parental perspective regarding their food allergy educational needs. The focus group methodology allowed us to obtain in-depth understanding of the educational needs of parents' managing their children’s food allergies, collect their recommendations for newly diagnosed families, and identify their preferences regarding dissemination methods. This methodology was crucial for this initial study. Pre-conceived questionnaires or surveys about preferences may have missed identifying key information generated here such as preferences for management “roadmaps”, emphasis on understanding concepts such as “cross contact”, preference for “branded” materials, and suggestions to disseminate information beyond pediatricians so that parents can be alert to possible food allergies prior to a doctor diagnosis, among others. We included enough descriptive detail in the results to evoke a vivid picture of the educational needs, concerns and experiences described by the participants. Although some specific suggestions about management voiced by individual participants requires caution (e.g., parental comment that all children with atopic dermatitis require a food allergy evaluation is incorrect), the overall requested approaches to education reflect valid concerns.
Limitations
Focus groups have several limitations. Sometime it is difficult to quantify or draw conclusions from information collected in a group setting. To overcome this limitation, we conducted a thorough analysis of the scripts by categorizing and coding comments. This approach allowed some appreciation of the relative importance of parents’ needs and lessons learned. Comments that were repeated across groups were more likely to reflect the consensus of parents. Another limitation is that focus group data may not be generalizable to other populations because participant selection is both nonrandom and potentially non-representative. We were cognizant that participants in the two cities, Little Rock, AR and New York, NY, represented populations with different geographical and cultural influences; however collecting data in both places enhanced the possibility of uncovering experiences and perceptions that supersede local influences. We recruited parents through allergy clinics to include experienced parents that could identify the key information that help them improve/understand food allergy management and make recommendations regarding the format of the educational material as well as methods of dissemination. Our sample may therefore be biased toward highly motivated families of children with more severe food allergies and ready access to healthcare.(31) In addition, participants were predominantly comprised of affluent, non-minority families, and therefore, these results might not be generalized to less affluent, minority parents and children. Focus groups are further influenced by personal motivation to participate (interest in giving opinions, interest in a topic, interest in meeting others to discuss a topic, seeking additional information about a topic, monetary compensation, etc.). Despite these limitations, the range of specific comments about pitfalls and opportunities for educational approaches appears to have been comprehensive and reflects a broad range of past educational exposures (or lack thereof) leading to successes and failures in management.
