Standardized of Peabody Developmental Motor Scale (PDMS) in First Grade Elementary School Children in Tehran

Motor development is considered as a part of the process of growth and development in which the child, firstly gains control over his own body function, and then utilizes it for interaction and manipulation with the environment. The aim of this study was to standardize of Peabody Developmental Motor Scale (PDMS) in normal children aged 72 to 83 months living in Tehran. This cross–sectional study was performed on 180 normal students (90 male, 90 female) and data was collected by PDMS. The results of this study demonstrated that the mean of Developmental Motor Queition Gross (DMQG) for male was 120.5 and for female was 120.40 and the Developmental Motor Queition Fine (DMQF) for male was 125.69 and for females was 126.66, respectively. There was not significant difference between male and female in DMQ and Mean Motor Age Equivalent (MMAE) (p<0.05). There was significant difference between DMQF and AEFM (p<0.05) and also between mean Age Equivalent Fine Motor (AEFM) and MMAE (p<0.05) of children living in different parts of Tehran. There was also significant association between MMAE and DMQ (p<0.01). PDMS can be used as a reliable and valid instrument for assessing any intervention and treatment of motor skills in children. Children with better motor skills have higher score of DMQ.
