الخصائص السيكومترية لمقياس أبراكسيا الكلام لدى تلاميذ المرحلة الابتدائية

Abstract EN

The current study aims to prepare a scale of a praxia of speech and verify its psychometric properties, and it sought to answer the following two questions: what is the factorial structure of the scale among a sample of primary school students?, and do the scale has high validity and reliability?.

the study sample consisted of (120) students in the fifth and sixth grades of primary school, ranging from approximately 10 to 11 years in the old al-Matania joint school affiliated to al-Ayyat educational in Giza governorate, with an average age of defense (10.58) and a standard deviation of (0.98) during the 2021 / 2022 school year.

the study found that the factorial structure of the speech apraxia scale for a sample of primary school students falls into four factors: the rhythm and motor control dimension of sounds, the pronunciation of speech sounds dimension, the behavioral features dimension, and the motor imitation dimension.

the scale also has high stability, as the Cronbach's alpha values for the dimension reached rhythm and motor control of sounds (.821,), after pronunciation of speech sounds (.756,), after behavioral features (.759,), after motor imitation (.735,), and the scale as a whole (.910,).
