The weakness of visual perception skills and reduced visual memory leads to reading and math impairment. Therefore, it is essential to develop a test to achieve this goal

the present study by the purpose of making and normalization of the test of cognitive ability has been accomplished for diagnosis of preschool students’ cognitive ability to achieve this purpose based on theorical literature, a test was prepared the test of cognitive ability has been formed of seven part :(the detection of objects is also a rhyme, understand the numbers of the image, write like a pattern, contact pictures) it’s content was confirmed by professor of psychology and consultants and then was performed on a sample of 206 preschool students. The questions were analyzed by suitable statistical method, and validity, reliability and normalized scores were determined.

base on accomplished account the internal consistency coefficient of subscale of the detection of objects is also a rhyme, understand the numbers of the image, write like a pattern, contact pictures are , respectively, 0.51, 0.42, 0.73 and 0.50 and total scale of cognitive ability is 0.67. to determine the validity of construct and composing component of the tests methodology of the main component by rotation in varimax method was used which 4of them were nameble. Conformity factor analysis also was used to determined validity of factor, that the conformity factor analysis confirms that the structure of questionnaire has an acceptable fitness to data and also confirms all of the goodness of fit indices of model. Raw scores were converted to normalized scores(Z, T, IQ) T-test independently demonstrate that there is a significant difference between average scores of girl and boy students In factor of cognitive ability. To investigate concurrent validity, we used of visuospatial perception test. The results of Pearson test showed that there is a significant connection between these two variables. regarding to the obtained validity and reliability, cognitive ability test is a tool that can be used in learning disability and consultation centers

This study evaluated the psychometric properties of the new version Tehran Intelligence LaboratoryStanford-Binet centers of learning disabled students learning disorders related to special education was discussed. Given the sample size of 523 patients from all centers of learning disabilities, to evaluated the validity using Cronbach alpha, test-retest and split-half, and the error of measurement -measurement was obtained. Also, in order to validate the diagnostic validity studies for three reading ability, and focus were used to calculate sensitivity coefficients were calculated in the interpretation of diagnostic validity. In addition, confirmatory factor analysis was used to examine the internal structure and psychometric findings survey indicated that the Factor validity of the instrument has been validated and this instrument as a Creditand valid and reliable tool for screening and diagnosis of learning disabilities.

current study done With The main objective of analysis the Psychometric Properties and factor structure of Hexaco personality inventory. Comparison the Hexaco personality inventory whit five main factors of personality encompasses the purpose of this study. Hexaco has three different forms. In this study a hundred questions form has been studied. The validity of this test Was investigated with use of three methods determination of internal consistency coefficient of factors and Procedures (Cronbach's alpha and Guttmann model) , Retest and the correlation with personality inventory NEO-FFI-60 (Convergent validity). For Survey the Validity of Hexaco test-100 used two of statistical methods Confirmatory factor analysis and exploratory. People in the sample have formed 502 person (270 men , 232 women) of students that they chose with Available Sampling method from Tehran university. The results of the exploratory factor analysis showed that six factors are extracted, is compatible. As well as confirmatory analysis showed that six factor model of Hexaco personality inventory has an acceptable fitness.The correlation between five main objective of personality that Measured by inventory NEO with Hexaco inventory is between 0.43 up to 0.73 that is meaningful in level of 0.01 and 0.05. From study the reliability of inventory with two method of Guttmann model and Cronbach's alpha obtained amounts between 0.62 up to 0.74 that is meaningful in level of 0.01 and also the results of retest in range 0.59 up to 0.81 is meaningful in level of 0.01 . From all of recent research findings that Hexaco test-100 has acceptable and intermediate validity and reliability to use between students society in Tehran .

The aim of the present respectively study was to investigate the validity and reliability of perception aging questionnaires (ASQ) in old people in Tehran.

For estimating the parameters of psychometric questionaires, 502 people (including 373 subjects aged 80-60 years and 129 subjects aged 59-50 years, 49.4 % male and 50.6 % female) were chosen for sampling multi-dimensional perception of aging questionnaires in Tehran, which is comprised of two parts, the first part of the vision of aging (aging), and the second part of the experience related to changes in cheers executed for them.

Data analysis showed that the internal consistency aging perception questionnaire, for the first part consisting of 32 items is 0.82 and the second part consists of 17 two-part is 0.88. The coefficients for the components of the questionnaire between 0.63 to 0.81were estimated. Test- retest reliability coefficient over the period of two months to two components of the questionnaire and all were statistically significant (P<0.01). To check the construct validity of the principal components analysis was used. adequacy of samples taken in the two sectors are equal to 0.871 and 0.728, and Bartlett's test of sphericity showed significant favorable conditions for factor analysis was performed. Based on these findings, the perception of aging in the first part of the questionnaire is saturated seven of the total 50.24 % of the total variance. The second part of the single-factor structure, to evaluate changes in health-related experiences in the narrative, in this case about 21.36 % of the total variance that is. And significant correlation between the components of aging and cognition questionnaire measures quality of life questionnaire score (P<0.01) represents the criterion validity of the questionnaire.

This questionnaire is reliable and valid scale to measure perception of aging in Iranian elderly.

The purpose of this study was to investigate the   confirmatory factor analysis of Applied metacognition questionnaire in group exercise. The statistical population   of the study consisted of all professional athletes in the first group and   the national league of group disciplines (football, volleyball, handball, and   basketball). The sample included 800 athletes selected by random cluster   sampling. The applied metacognition questionnaire in group exercise consisted   of 30 items that were graded with a five degree Likert scale (from very low =   1, very much = 5). The results of Factor analysis showed that the quadratic   model is consistent with the exploratory factor analysis of the questionnaire   for the purpose of separation of questions and adaptation. The reliability   obtained using Cronbach's alpha for quadruple factors ranged from 0.51 to   0.73, indicating a good reliability of the tool. The results of confirmatory   factor analysis indicated that the four-factor model of metacognitive   questionnaire in group exercises, including perceived speed, planning,   self-esteem, and awareness with appropriate fitness.

The aim of this study was to investigate the factor structure of Kaboriand Tanno’s multidimensional perfectionism questionnaire in high school girl students and its relationship with aggression. The statistical population consisted of female high school students in the year 2016. Five hundred students completed the multidimensional perfectionism questionnaire (Kabori and Tanno, 2004) and the aggression questionnaire (Abolmaali, 2013). Data were analyzed by confirmatory factor analysis.The results of the confirmatory factor analysis indicated that the model was fitted with the data collected and the existence of three factors (Personal Standards, Pursuit of Perfection, Concern over mistake) were confirmed. Correlation between perfectionism and aggression components was positive and significant. The evaluation of correlation coefficients between the components of perfectionism questionnaire showed that this questionnaire had a satisfactory internal correlation. In addition, the internal consistency of the dimensions of perfectionism questionnaire in terms of personal standards, Pursuit of Perfection, Concern over mistake) was 0/82, 0/84 and 0/84 respectively. Considering the desirable validity and reliability of this questionnaire, it is recommended to use it in research activities and psychological assessments.
