Abstract:
Objective: To translate the food allergy quality of life-parental burden (FAQL-PB) scale into Chinese and test its reliability and validity among the caregivers of children with food allergy. Methods: The caregivers of 222 children with food allergy were enrolled by convenient sampling from October 2020 to October 2021 in the Children's Hospital Affiliated to Chongqing Medical University. The forward-backward translation and cultural adaptation of the original FAQL-PB scale was performed in accordance with Brislin's model. Item analysis was used to select items. The validity of the questionnaire was analyzed with the item-level content validity and the exploratory factors analysis. And the internal consistency coefficient, split-half reliability and test-retest reliability were used to evaluate the reliability of the questionnaire. Results: The Pearson correlation coefficients of the scores between each item and total scale ranged from 0.72 to 0.88 (P<0.01). The item-level content validity index (I-CVI) ranged from 0.83 to 1.00, scale-level content validity index/universal agreement (S-CVI/UA) was 0.94, and scale-level content validity index/average (S-CVI/Ave) was 0.99. Exploratory factor analysis revealed that Chinese version of FAQL-PB scale could be classified into two dimensions: emotional distress and limitations on life, with the accumulative variance contribution rate of 74.08%. The Cronbach's α coefficient, split-half reliability coefficient and test-retest reliability of the Chinese version of FAQL-PB scale were 0.97, 0.98 and 0.71, respectively. Conclusion: The Chinese version of FAQL-PB scale is proved to be reliable and eligible, and can be used as a specific tool to investigate the quality of life in family of children with food hypersensitivity.
