2022, Journal of Trace Elements in Medicine and BiologyCitation Excerpt :A special clinic was set up in the study hospital for the neurodevelopment tests of the children, and the tests were performed by two professional pediatricians. Internal consistency has been presented as an aspect of reliability, estimated using Cronbach's alpha coefficient [4]. The cut-off values for the Cronbach's alpha values were classified as: unacceptable (<0.7), acceptable (0.7–0.8), good (0.8–0.9), and excellent (>0.9) [9,41].
