Abstract:The aim of this study concerned with validating the fifth version of Wechsler Children’s Intelligence Test on Iranian children aged between 6 and 16 years old.According to the statistics of students studying in elementary school and junior high school, 1200 people were selected as a multi-stage cluster research model. Wechsler Children’s Intelligence Test 5th edition and Wechsler Children’s Intelligence Test 4th edition, were the measuring instruments. The reliability of subtests, intelligence quotient and indexes were performed using three following methods: bisection, Cronbach’s alpha, and retesting.To calculate and analyze the test validity, the criterion method was simultaneously performed on 240 people with the correlation of indexes and Wechsler 5 intelligence with Wechsler IV; and structural validity through exploratory and confirmatory factor analysis. To analyze and operation of all subtests, the difficulty coefficient and discriminative coefficient were calculated. The results of the findings of the all three methods used for reliability showed that this test is highly validated in Iran, and the results were consistent with the results of the same test compare in the United States. The difficulty and discriminative coefficient of the questions were appropriate in Iran. Due to the up-to-date and high psychometric properties of this test in Iran and obsolescence of previous versions, it is recommended to use this test to evaluate children aged between 6 and 16 years old in Iran. Keywords: Intelligence, Reliability, Validity, Wechsler Intelligence Test for Children 5th edition and Iranian Elementary and Junior High School Students 6 to 16 years old

Background: The ability to understand and being able to profoundly and deeply understand the within-person differences entail profile analysis which is considered to be a serious challenge in psychometrics area. Aim: This study was aimed at applying Profile Analysis via Multidimensional Scaling (PAMS) procedure in order to extract prototypical profiles underlying the Wechsler Intelligence Scale for Children- Fourth Edition (WISC-IV). Method: The design of the study is correlational and the population of the study consisted of all of the students studying at 6th distinct schools of Tehran. Using random cluster sampling method 200 students were selected. The sample were administered full subscales of WISC-IV. Results: Data analysis using the PAMS procedure resulted in extracting 3 cumulative profiles. Statistically meaningfulness of the subtests within profiles were determined and they were labeled according to their dimensionality and underlying meaning (processing speed vs. working memory, lexical knowledge vs. visual alertness and perceptual reasoning vs. verbal comprehension). Conclusions: using the PAMS procedure in interpreting WISC-IV results could be beneficiary. Relying on individual parameters further clinical and applied implications are discussed.

The aim of the research was identification of Wechsler intelligence scale for children (WISC-IV) basic attributes based on Cattle- Horn- Carrol (CHC) narrow abilities by using generalized DINA (G-DINA) cognitive diagnostic model. The population of the research was all of Iranian primary school students which randomly 1222 students selected. We use Wechsler intelligence scale for children (WISC-IV) for gathering data. Results show that from the nearly 70 CHC narrow abilities, 9 narrow ability (visualization, induction, working memory, general verbal information, lexical knowledge, flexibility of closure, memory span, language development, general sequential reasoning) Identified as basic attribute of WISC-IV. Also from the constrained models, the LLM model based on Wald statistics was chosen. Additionally, most of student mastered in lexical knowledge and the lowest rate of mastering belongs to flexibility of closure. finally, the probability of guessing parameter in easy items was high and probability of slipping in difficult items was high.

Background: The research is based on of Gardner’s Multiple Intelligence according which we can adjust teaching methods and materials in harmony students kind and level of intelligence.Objectives:The present research was aimed to construct and standardize a questionnaire onGardner’s multiple intelligence.Methods: The sample group consisted of 811 under graduate students in different branches of Roudehen Islamic Azad University in the second semester of academic year 1389-90. The sample group was randomly selected via multistage stratified sampling. The instrument was constructed according to Gardner’s theory and research literature and same of the available questionnaires. The reliability of the questionnaire was estimated using Cranbach Alpha coefficient, which range from 0.663 to 0.824 for different categories of questionnaires.The construct validity of the questionnaires was estimated using component principle analysis by varimax rotation.Results: The findings of research showed that 1) The questionnaires have a acceptable reliability and construct validity. 2) Independent groups t test showed that there was no significant difference between boys and girls except for bodily – kinesthetic intelligence. 3) Table of norms was computed for different test questionnaires based on deviate IQ (M=100,sd=15) for girls and boys.Conclusion: This instrument could be used for recognition of students intelligence and can be viewed as prelimitary step for future educational planninig and decision making for education.

The present study aims to examine the relationship between students’ psychological profile in Wechsler intelligence test for children -fourth edition- (W1SCJV) and multiple intelligence (Ml) based on Gardner's theory among students of fifth grade elementary school in Isfahan city. The study was descriptive and correlative. Sample population consisted of 30 students who were selected using multistage sampling. The measuring instruments used were Gardner’s multiple intelligence questionnaires and Wechsler intelligence scale for children -fourth edition- (WiscJV). The data was analyzed using correlation coefficient. The results of this study showed that there are significant relationships between Gardner’s verbal-linguistic intelligence subscales and Wechsler’s visual concepts, between Gardner’s visual-spatial intelligence and Wechsler’s encoding and speed, between Gardner’s interpersonal intelligence and Wechsler’s digit span and visual concepts subscales, and finally between Gardner's intrapersonal intelligence and Wechsler’s digit span (p<0/05). However, there was no significant relationship between other subscales. It can be concluded that Gardner's multiple intelligence questionnaires should be used circumspectly as a diagnostic test for measuring intelligence in traditional sense.

Background: The Multidimensional Aptitude Battery (MAB) is a group intelligence test based on the Wechsler Adult Intelligence Scale- Revised (WAIS-R). The MAB is designed for the assessment of a wide range of intellectual abilities of both adults and the16-year old or older adolescents. Objectives: The purpose of the present research was to investigate the adaptation, normalization and the psychometric propertiesof the Persian version of the MAB among the Payame Noor Universitystudent population. Methods :First, the subtests were translated into Farsi. Then, some of the subtest items were adapted to the Iranian culture and were ready to be used. Finally, after the pilot study and resolving the errors, the final subtests were administered to a sample group consisting of 315 students of humanities and basic sciences in Payame Noor University of Tabriz.In this study, the mean and the standard deviation of the subtest raw scores were used to produce the standardized scores (with a mean of 50 and a standard deviation of 10) and then the standardized score conversion chart was formulated. Results: The results of the internal consistency and test- retest reliability revealed that the MAB is adequately reliable. All the subtests had middle and high correlations with Raven’s Advanced Matrices’ intelligence test scores, which showed concurrent validity of these subtests. The correlation coefficients in the multidimensional aptitude subtests were in the range of 0.18 to 0.58. The correlation between the general information, vocabulary and picture completion subtest scores and age was positive and significant, but the correlation between digit symbol, spatial, picture arrangement and object assembly and age was negative and significant. The summary of the regression coefficient results showed that vocabulary subtests were the best predictor of the total score of verbal scale and the spatial subtests were the best predictor of the performance scales and the other subtests were of lower ranks. Conclusion: The results of the study indicated that the Persian version of the MAB is a reliable and valid measurement tool that can be used for academic and career counseling purposes, and basic researches.
