Investigation of the Validity and Reliability of the Turkish Version of the Basic Activities of Daily Living Questionnaire in Preschool Children.

Basic Activities of Daily Living-Preschool Period Tool (BADL-P) is a fast and quick test that does not require a special environment, where activities of daily living (ADLs) in preschool children are questioned. The aim of the study was to conduct a Turkish reliability and cultural adaptation of the BADL-P. The study was conducted among 211 parents of preschool children. Validity was determined using exploratory factor analysis. To determine convergent validity, the Functional Independence Measure for Kids (WeeFIM) scale was used. Cronbach's alpha, intraclass correlation coefficient (ICC), and item-total correlation (ITC) values were calculated to assess the reliability of the BADL-P. Totally, 99 girls and 112 boys, aged 3-6 years, with the children's mean age of 4.50 ± 0.75 years (3 years = 11%, 4 years = 32.1%, 5 years = 52.2%, and 6 years = 4.8%), were included. Exploratory factor analysis revealed that the BADL-P had sufficient fit. The BADL-P was weakly to highly correlated with the WeeFIM (p < 0.05 and p < 0.001). Cronbach's alpha and ICC values of the BADL-P were acceptable (0.912 and 0.837, respectively). The ITC values of each item of the BADL-P were also acceptable (ranged from 0.232 to 0.683). Children in the 5-6 age group demonstrated higher scores and exhibited more advanced development in the ADL areas compared to children in the 3-4 age group (p < 0.05). The Turkish version of the BADL-P is valid, reliable, and sensitive to assessing and monitoring the performance of Turkish preschool children in ADL.
