Objective Feeding disorders in children have multiple adverse consequences at personal, economic, and sociocultural levels, making them one of the major public health challenges. As speech and language pathologists play a key role in the multidisciplinary management of these disorders, they require valid and reliable tools to screen infants’ and children’s feeding behaviors. Therefore, this study aimed to translate the infant and child feeding questionnaire (ICFQ) into Persian and to evaluate its psychometric properties among Persian-speaking children.
Materials & Methods This psychometric study was conducted on 220 children aged 0–4 years (100 children with feeding disorders and 120 typically developing children). Translation process included forward translation, evaluation of face and content validity, backward translation, and cognitive interviews for face validity. Construct validity was assessed through convergent validity with the Pedi-EAT questionnaire and known-groups validity. Criterion validity and diagnostic accuracy (sensitivity, specificity, and cut-off point) were also evaluated. Data analysis was performed using SPSS software, version 25, applying statistical tests such as Pearson’s correlation coefficient, independent t-test, chi-square test, and ROC analysis.
Results The Persian version of the ICFQ demonstrated satisfactory validity and acceptable psychometric properties. The content validity index (CVI) was 0.95, indicating excellent content validity. The Persian version of the ICFQ demonstrated a significant correlation with the Pedi-EAT questionnaire (r=0.46, P<0.01). Agreement with specialists’ diagnoses was reported at 90.3% (χ²=157.03, P<0.01). The area under the receiver operating characteristic (ROC) curve was 0.97, with a 95% confidence interval ranging from 0.96 to 0.99. The optimal cut-off point was determined to be 2.5, yielding a sensitivity of 93% and a specificity of 91.7%.
Conclusion The Persian version of the ICFQ is a valid instrument for screening feeding disorders in Persian-speaking children and serves as an efficient tool for both clinical and research applications.
