Turkish validity and reliability of the Activities of Daily Living Evaluation in Schoolchildren (ADL-E) Questionnaire

Purpose: Activities of Daily Living- Schoolchildren (ADL-E) Questionnare is designed to assess activities of daily living in school-age children. The aim of study was to investigate the validity and reliability of the Turkish version of the ADL-E Questionnare. Methods: This study is a metadological research. The parents of 412 children with typical development between the ages of 6 and 12 participated in the study. The ADL-E Questionnaire includes four different scales: three for basic activities of daily living, such as eating (20 questions), personal hygiene (29 questions) and clothing (17 questions), and one for general functionality (18 questions), which assesses the cognitive aspects required for performing basic activities of daily living. The questionnaire contains 84 questions in total. Construct validity was determined using exploratory and confirmatory factor analysis. Internal consistency was examined using Cronbach’s α coefficient. The test–retest reliability of the ADL-E subscale scores were assessed using the intraclass correlation coefficient (ICC). Results: The mean age of the children was 9.511.40 years. 205 girls and 207 boys. Construct validity analysis revealed that the ADL-E had adequate fit. The Cronbach's α coefficient value of the ADL-E Questionnaire was excellent (0.816) for the overall questionnaire. Except for the oral sensitivity and executive functions sub-items, all values in the sub-item-total correlation results were greater than 0.30. The test-retest values of the ADL-E Questionnaire were between 0.755-0.949. Conclusion: The ADL-E Questionnaire was found to be valid and reliable in Turkish for the assessment and monitoring of ADL performance of Turkish children.
