Preliminary Psychometric Validation of Developmental Milestones of Children’s Play Among Children Aged 1 - 4 Years

Summary/Abstract: Children's play is an important activity which benefits their normal development. There is small body of research that dealt with children’s developmental milestones of children’s play, especially those of children aged up to four years. Therefore, we conducted a study on 637 children aged one to four years. The main goal of our study was to conduct preliminary psychometric evaluation of the instrument constructed for this purpose. The instrument is called "Milestones Development of Children's Play" (MRDI), and it consists of three check-lists, suitable for the following age groups: 1-2 years (MRDI12), 2-3 years (MRDI23) and 3-4 years (MRDI34). The results show a satisfactory factor validity of all three parts of the MRDI, a solid reliability of the MRDI23, and somewhat lower reliability of the MRDI12 and the MRDI34. Lastly, we discussed on possible improvements of these instruments, through improving their discriminative properties, and the number of their items.
