Development and validation of assessment tools for food allergy–related knowledge and management confidence

BACKGROUND: Given the life-threatening nature of food allergy (FA), it is important to assess the level of knowledge among families with food-allergic patients and their ability to cope with anaphylaxis. This study constructed a FA knowledge questionnaire (FAKQ) and confidence in FA management skill...

description BACKGROUND: Given the life-threatening nature of food allergy (FA), it is important to assess the level of knowledge among families with food-allergic patients and their ability to cope with anaphylaxis. This study constructed a FA knowledge questionnaire (FAKQ) and confidence in FA management skills (CIFAMS) questionnaire to assess understanding and attitudes toward FA management in food-allergic families. METHODS: Items from literature review and expert panel showing ≥80% content validity index and semantic equivalence were selected for translation into Chinese. These questionnaires underwent feasibility pilot testing followed by cross-sectional validation to assess their psychometric properties of internal consistency, test–retest reliability, and construct validity with a FA quality-of-life questionnaire and discriminant validity. Exploratory factor analysis was performed to confirm their factor structure. RESULTS: A total of 155 subjects (104 patients and 51 parents) completed a 20-item FAKQ and 10-item CIFAMS. Both tools showed acceptable internal consistency in baseline and retest groups. FAKQ and CIFAMS correlated for all subjects (P = .002) and for adults (P = .002), and similarly between CIFAMS and parent-reported FA independent measure (P = .005). Total score of FAKQ was sensitive to within-group differences of patients hospitalized for FA (P < .001). FAKQ and CIFAMS items were factored into 4 and 2 domains, respectively. Subjects scored the lowest on FAKQ items about signs of allergic reaction and CIFAMS items on epinephrine autoinjector use. CONCLUSION: FAKQ and CIFAMS developed by our group are valid and reliable in assessing knowledge and confidence in FA management in patients and parents. These tools are crucial for formulating education programs and advocacy campaigns for FA.
