Abstract
The purpose of this study was to investigate the reliability of Dortmund Developmental Screening for Preschools (DESK) 3–6 for children 4-years of age through the use of methods such are internal consistency reliability, test–retest and Cronbach’s alpha, as well as check its suitability on a different sample. Participants were 413 preschool children (206 males and 207 females) with ages ranging from 48 to 59 months. The DESK was used. Results revealed that the original version of DESK 3–6 for children 4-years of age shows problems in internal consistency, adequate Cronbach alpha and test–retest coefficients. It is concluded that the present instrument appears to carry enough data to justify its use on other samples as well.
