Key Points

The study aimed to validate Korean versions of food allergy anxiety scales and identify associated factors for anxiety in children and parents.
Enrolled Korean patients aged 6-18 years with food allergies and their parents.
Translated English anxiety scales into Korean and assessed their internal consistency using Cronbach's coefficients.
Evaluated convergent validity by correlating anxiety scales with a quality of life questionnaire and generic anxiety scales.
Performed logistic regression analyses to identify factors associated with high food allergy anxiety.
K-SOFAA-C, K-FAAS-C, and K-SOFAA-P showed excellent internal consistency (Cronbach's > 0.80).
Total scores correlated significantly with K-FAQLQ scores and generic anxiety scales (all P < 0.05).
Respiratory symptoms were linked to higher anxiety scores for both K-SOFAA-C and K-SOFAA-P.
Living in non-metropolitan areas was associated with increased anxiety scores in K-FAAS-C.

Abstract

Purpose: This study aimed to evaluate the reliability and validity of the Korean versions of the Child-and Parent-Rated Scale of Food Allergy Anxiety (K-SOFAA-C and K-SOFAA-P) and the Food Allergy Anxiety Scale for Children (K-FAAS-C).Additionally, we sought to identify factors associated with high levels of food allergy (FA)-related anxiety in Korean children and their parents.Methods: We enrolled patients aged 6-18 years with FA and their parents.The original English versions of the SOFAA-C, SOFAA-P, and FAAS-C were translated into Korean.Internal consistency was assessed using Cronbach's coefficients.Convergent validity was evaluated by examining the correlations between each questionnaire and the Korean version of the Food Allergy Quality of Life Questionnaire (K-FAQLQ) as well as generic anxiety scales.Logistic regression analyses were performed to identify factors associated with high anxiety.Results: The K-SOFAA-C, K-FAAS-C, and K-SOFAA-P demonstrated excellent internal consistency, with Cronbach's values exceeding 0.80.Total scores of the K-SOFAA-C, K-FAAS-C, and K-SOFAA-P showed significant positive correlations with age-appropriate K-FAQLQ scores (r = 0.469, 0.886, 0.549, 0.929, and 0.665; all P < 0.05) and with generic anxiety scales (r = 0.621, 0.393, 0.269, and 0.348; all P < 0.05).Respiratory symptoms were significantly associated with higher K-SOFAA-C (adjusted odds ratio aOR, 4.38; 95% confidence interval CI, 1.12-17.17)and K-SOFAA-P scores (aOR, 10.57; 95% CI, 1.94-57.52).Residing in non-metropolitan areas was associated with higher K-FAAS-C scores (aOR, 3.72; 95% CI, 1.06-13.11).
