The purpose of this study was to investigate the psychometric properties of the scale of response to sexual rejection in married women in Ardabil. The statistical population of this study consisted of all married women in Ardabil. From the statistical population, available sampling method and individually responded to the sex rejection scale. Internal consistency coefficient and confirmatory factor analysis were used for data analysis. Data were analyzed using SPSS 25 and LISREL 8.8. The results of internal consistency coefficient showed that this scale has good reliability. The cronbach's alpha reliability of the scale for the four factors of understanding are resentment 0.83, uncertainty 0.86 and temptation 0.83. Confirmatory factor analysis fit indices showed validity of the scale (CFI = 0.98, RFI = 0.96, NNFI = 0.98, RMSEA = 0.062). The results of this study suggest that the RSRS scale is a reliable and valid tool for measuring response to sexual rejection

The purpose of this study is to examine the questions of the Likert scale with the Classical Test Theory and the Item Response Theory, then putting together the results of these two approaches and answering the question "Are the results of these two approaches consistent? or do they contradict each other?" . The research method is descriptive and in terms of data, it is a secondary analysis method. The subjects studied in this research included 977 students of the junior high school students, that by removing individuals in the data screening stage, finally, the analysis of extraversion items was based on the information of 783 subjects, the analysis of openness items on the information of 763 subjects, and analysis of conscientiousness items on the information of 784 subjects. The research instruments were 3 subscales of extraversion, openness and conscientiousness of the Neo Personality Test. The results of the statistical analysis showed that the higher the internal consistency of the items, the more accurate and valid the results obtained from the graded response model, and for items with low internal consistency through this model, it should be acted cautiously; Because it may show the threshold of the items inverted or the discrimination coefficient of the questions false negative or positive. All in all, the simultaneous use of different methods of statistical analysis will be of aid in better analysis and obtaining more accurate results.

The visuospatial development is one of the most important foundations of development, since it plays the role of the primary function of all learning and communication, and forms the mental representations of the outside world. On the other hand, this development simultaneously contains spatial information and directs all movements in space. Measurement of this development and its various dimensions is vital in the early years of life, since with this information we can estimate the visuospatial capacity of the child and examine the change of this basic capacity during life span. The aim of the present study was to provide psychometric properties for the visuospatial development questionnaire (Harry Wachs, 2014) for use in Iran. A questionnaire was filled out on 348 preschool children in Mashhad that were selected randomly by multistage stratified sampling method and psychometric indices were calculated using statistical software. The findings showed that the questionnaire had a satisfactory content and structure validity and also reliability. The results of the confirmatory factor analysis also showed that the structure of the questionnaire has an acceptable fit with the data. These factors were named in accordance with the main research, body awareness and sense; location of body in space; relation of object to self, other objects and people; conservation of space; Visual-logical reasoning; Representational thought; their coefficients of internal consistency were 0.83, 0.79, 0.67, 0.80, 0.72 and 0.61, respectively. These results show that the Visuopatial development Questionnaire can be used as a tool for measuring the concept of the visuospatial development in Iran.

The current investigation was aimed toward testing the factor structure and Measurement of internal consistencyof academic well-Being questionnaire (AWBQ).Method:Three-hundred and sixty five students from school of Poldokhtar city (189 male and 176 female) were selected through multi-stage sampling method. Students completed the Farsi version of AWBQ and the academic stress questionnaire (ASQ). The exploratory factoranalysisand confirmatory factor analysis and internal consistency were used to compute the AWBQ's factorial validity and reliability, respectively.Findings:The results of principle component analysis (PC) and oblique rotation replicated the four-factor structure of the AWBQ. Based on item content, factors were named difficulty with school values, school burnout, satisfaction with educational choice and schoolwork engagement. Based on AMOS software, Goodness-of-fit indices of confirmatory factor analysis confirmed the 4 extracted factors. The multidimensional scales of AWBQ were shown to be an acceptable measurement model in this sample. The significant correlation between the AWBQ factor score and it’s dimensions with total score of academic stress confirmed the validity of the AWBQ.Conclusion:These findings speak to the robustness of the AWBQ, in revealing its relatively stable structure, and consequently, to its potential usefulness as a valid measure of academic well-being for Iranian students.

Abstract Background: Aside from test anxiety scales, measurement instruments assessing students’ achievement emotions are largely lacking. Therefore, the main purpose of the present study was to investigate factorial validity of the Class-Related Emotion Scales (CRES) among Iranian university students. Method: 400 university students (240 male, 160 female) completed the Class-Related Emotion Scales. The confirmatory factor analysis method and internal consistency were used to compute the CRES's factorial validity and reliability, respectively. Results: The results of confirmatory factor analysis, based AMOS software, indicated that multidimensional structure of the CRES consisted enjoyment, hope, pride, anger, anxiety, shame, hopelessness and boredom had acceptable fit to data in the Iranian sample. The results of the confirmatory factor analysis by replication multidimensional factorial structure of the Farsi version of the CRES consisted of 8 scales measuring enjoyment, hope, pride, anger, anxiety, shame, hopelessness, and boredom during class indicated that the scales were internally valid. Internal consistencies for the scales measuring enjoyment, hope, pride, relief, anger, anxiety, shame, hopelessness, and boredom during class were 0.93, 0.92, 0.89, 0.89, 0.89, 0.91, 0.93 and 0.95, respectively. Conclusion: In sum, on the one hand, the results provide further support for the control-value theory and on the other hand, these findings provide evidence for the validity and reliability of the AEQ as an instrument to measure of achievement emotions among Iranian university students.

This study is an attempt to examine the psychometric properties of the academic engagement scale formulated by Tinio in 2009. The academic engagement scale was administered to a sample volume of 358 students who were randomly selected thorough the process of cluster sampling. The construct validity, convergent validity and internal consistency of the scale were calculated by exploratory factor analysis, confirmatory factor analysis, Pearson's product-moment correlation coefficient and Cronbach’s alpha coefficient. The results of principle component analysis and oblique rotation demonstrated that the academic engagement scale had three factors. The goodness of fit indices of confirmatory factor analysis also confirmed the three factors. Moreover, the multidimensional scales of academic engagement scale were shown to be an acceptable measurement model in this sample. The correlation coefficients between academic engagement subscales were positive and significant (p<0.05), which confirmed the convergent validity of the scale. Regarding the internal consistency, the alpha coefficient was calculated as 0.96, behavioral engagement as 0.90, emotional engagement as 0.92 and cognitive engagement as 0.88 of the total scale. In conclusion, Tinio's scale was proved to be a valid and reliable instrument for measuring THE academic engagement of the Iranian students.
