Food allergy in adolescents: validation of the food allergy independent measure and the EuroPrevall food allergy quality of life questionnaire into Spanish
Sixty adolescents diagnosed with immunoglobulin E-mediated allergy to food completed the questionnaires. Cronbachs alpha was used to assess internal consistency; correlation between FAQLQ-TF and FAIM was used to test construct validity. The discriminant validity was evaluated by comparison with the number of offending foods, the perceived impact on social life, the diagnosis of anaphylaxis, and the previous prescription of adrenaline auto--injectors (AAI).
Results:
No question fulfilled criteria to be removed from the questionnaire. For FAIM, Cronbachs alpha = 0.763, and for the four domains of FAQLQ-TF, Cronbachs alpha = 0.7970.847. A significant correlation existed between FAQLQ-TF and FAIM, and of both of them with anaphylaxis and the prescription of AAI (P ˂ 0.05 for all comparisons).
Conclusions:
This Spanish translation of FAIM and FAQLQ-TF for adolescents had good internal consistency and construct validity as well as ability to discriminate patients according to the number of foods to avoid, impact on social life, diagnosis of anaphylaxis, and AAI prescription (AU)
