The Factor Structure of Reynolds Intellectual Assessment Scales, Second Edition in Student’s Sampad

The Aim of the present research is to investigate the " Factor Structure of Reynolds Intellectual Assessment Scales, Second Edition in student’s sampad " in the academic year 2017-2018. According to the main Aim of the research, a question has been asked to verify the validity of the structure. Second version of the measurement scale Inside Reynolds's Intelligence, students of the Tehran University have questioned the main question of internal structure research. The design of the present research, with emphasis on the process of codification and standardization, is in the field of methodological research and is a type of psychometric research and has been carried out using an orthogonal hierarchical confirmatory factor analysis. The results showed that according to the proposed model of internal structure in the field of four tests, the first factors (crystalline intelligence and fluid intelligence) can be suggested. The Reynolds Intellectual Assessment Scales, Second Edition has an internal structure of two factors And is in accordance with Cattel's proposed model. The Hierarchical model of cognitive abilities of Cattel, Horn and Carroll, entitled "Two Major Capabilities of the Ten Major Capabilities," has a special place. Therefore, crystalline intelligence and fluid can be discussed as two generic capabilities.
