Validity and Reliability of the Persian Version of Motor Observation Questionnaire for Teachers (PMOQ-T)

The aim of this research was to introduce the Persian version of Motor Observation Questionnaire for Teachers (PMOQ-T), and evaluate its reliability and several aspects of its validity in identifying children at risk of developmental coordination disorder (DCD) in Iran. We examined discriminante validity, construct validity, concurrent validity, and internal consistency of the PMOQ-T using a sample of 505 school boys and their teachers. Teachers were asked to complete the PMOQ-T. Teachers assessments were compared to students’ performance on the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) and Test of Gross Motor Development-2 (TGMD-2). PMOQ-T had a high internal consistency (Coronbach's alpha=0.91). The DCD at risk group scored significantly higher than the normal children in both BOTMP and TGMD-2. Explanatory factor analysis showed that the PMOQ-T was bi-factorial and the Persian version was compatible with the original. Finally, high correlations were observed between the PMOQ-T scores and "BOTMP (-0.75) and TGMD-2 subscales": locomotion (-0.68) and object control (-0.62). The results imply that the PMOQ-T can be considered a valid and reliable screening tool for Iranian children at risk of DCD.
