Investigating the psychometric properties and norming of the Multiple Fluid Intelligence Test (MMFTI) in 4-6 year old students

Abstract

The aim of the present study is to investigate the psychometric properties and norming of the Multiple Fluid Intelligence Test in first grade elementary school students. The sample size in this study was 800 people aged 7 to 9 years old, who were selected by purposive sampling method, and the required data were collected using the Multiple Fluid Intelligence Test (MMFTI). In this study, exploratory factor analysis with Varimax rotation method was used to examine the validity of the test construct. The Kaiser criterion and the Scarry criterion were used to determine the factors of the aforementioned questionnaire. The results of the extraction of 5 factors for fluid intelligence in both groups (perception, reasoning, attention memory, and verbal processing) in the age group of students 7 to 9 were. The results of the confirmatory factor analysis in fluid intelligence showed that the perception component had a factor loading of 0.32, the reasoning component had a factor loading of 0.49, the attention component had a factor loading of 0.58, the memory component had a factor loading of 0.55, and the verbal processing component had a factor loading of 0.65. As the results of exploratory factor analysis related to the test questions showed, the mean and standard deviation of all subtest questions were acceptable in relation to the total test score and the correlation of each question with the total test score was significant, and the reliability value of each question with the total test reliability value was also acceptable. Accordingly, the Cronbach's alpha coefficients in the components of fluid intelligence were respectively equal to reasoning 0.89, perception 0.79, attention 0.85, memory 0.74, and verbal processing 0.92, which indicated the desired internal consistency for the subscales of the Fluid Multiple Intelligence Test. Considering the appropriate coefficients of construct validity and reliability of all components of fluid intelligence, this test can be used as a norm test in the age group of 4 to 6 in kindergartens.
