AbstractThe aim of this study was to design a checklist of pre-number concepts in children aged 5 to 6 years and to examine its psychometric properties. To build this tool, library resources or documentary analysis were used. And the checklist contains 66 questions that have 5 components (classification, alignment, mental retention, geometry, detection of similarities and differences), which introduce pre-number concepts at different levels such as (five senses, memory and observation, Classification, thinking sequence, reasoning and problem solving, color concept, shape, mathematical concepts are prerequisites, environmental concepts related to natural, physical, social environment. This questionnaire was administered online in kindergartens and preschools and the statistical population The parents of the children were 5 to 6 years old and the samples included 100 parents.This checklist had 4 objectives: first, how the concepts before the number in children, second, determining the content and face validity, third, determining the reliability of the checklist, and finally determining the validity of the data. It was performed in SPSS22 software and descriptive index including mean, variance, graph, skew and also inferential statistics were evaluated by exploratory factor analysis and the result was that the checklist was reduced from 66 questions to 42 questions. Cronbach's alpha was about 0.6 and also for the internal consistency of the construct validity questionnaire. Confirmed. The questionnaire was also reviewed by 10 experts and the content and face validity of the questionnaire, which was based on the CVR, was about 2.2. And in research on children, about 0.86 of children have pre-number concepts in them.

The Sources of Counseling Self-Efficacy Scale, Malaysia (SCSE-M) is a self-report scale that measures self-efficacy with a focus on how counselors work with 25 items, however, this scale has not been investigated and psychometrically evaluated in Iranian society. The aim of the current study was, in the first step, to translate this scale from English to Persian and then to determine its psychometric properties in Iranian samples. The survey sample consisted of 297 of his 1400 Tehran city counselors, selected in a Convenience non-random sampling, and they responded to the research tools including Counseling Self-Efficacy Scale (2020), General Self-Efficacy Scale (1995), Deiner Flourishing Scale (2010), and Counselors Self-Efficacy Scale (2009). The data were analyzed using confirmatory factor analysis According to the findings, face validity, content, and structure showed the appropriate validity and reliability of this tool. We used the combined reliability, and Cronbach's alpha coefficient to assess the reliability and internal consistency of the Counselor Self-Efficacy Resource Scale, and the results showed that this scale has good internal consistency and composite reliability. Finally, the analysis of the correlation matrix related to the variables of the study showed that the Counseling Self-Efficacy Resource Scale had a positive and significant correlation with the general self-efficacy scale (GSE-10), Deiner Flourishing Scale, Counselors Self-Efficacy Scale, age and activity experience (p<0.01). The results of the present study demonstrated that this scale has favorable psychometrically properties in Iranian samples and can be reliably used in Iranian samples to assess self-efficacy in counseling.

Abstract
This research was conducted with the aim of investigating the validity, reliability and factor structure of the reading motivation questionnaire. The current research plan is among survey research and tool development. The statistical population of the research was all sixth grade students in Yazd city. The participants included a sample group of 300 sixth grade students in Yazd city in the academic year of 2021-2022, who were selected by multi-stage cluster random sampling method and responded to the reading motivation questionnaire of Schiffel and Schaffner (2016). For data analysis, factor analysis methods and Cronbach's alpha coefficient were used using SPSS26 and Smart PLS software. The results of factor analysis showed that the questionnaire consists of seven factors and has good fit indices. Cronbach's alpha coefficients for the whole scale and its dimensions fluctuated between 0.77 and 0.92. Finally, the Persian version of the "reading motivation" questionnaire has acceptable psychometric properties to measure the various reasons Iranian students read, and it can be used as a valid tool in research, educational and clinical situations.

Response time has always been a concern in ability measurement, sometimes implicitly as in time-limit tests, sometimes explicitly as in speeded tests, and sometimes as the main outcome variable. Therefore, this study seeks to investigate the application of response time model in measuring cognitive ability of the children's quantitative reasoning. To this end, a sample of 502 children from different areas of Tehran was recruited through Cluster sampling and evaluated with a quantitative reasoning test. To analyze the collected data, modeling response time with the hierarchical model was used. Item and person parameters were also estimated and interpreted. The modeling results revealed that in addition to the response correctness parameters, response time parameters including discrimination coefficient, difficulty coefficient and gamma also been estimated. Moreover, the estimated parameters of the response time model compared with the 2-pl IRT model in order to identify their main similarities and differences. Findings revealed that there are some differences in discrimination coefficients and Thetas of individuals, which indicates the power of the response time model. It is worth mentioning that the lowest differences were observed in the difficulty coefficients. Finally, based on the number of parameters, increasing the variance of theta scores, and research background support, the study and application of response time models in measuring children's cognitive abilities were suggested.

According to the objectives and subject, the method of this research is descriptive and of the type of factor analysis studies. The statistical population was all the students of the universities of Mashhad city, and 660 individuals were selected from this population by multi-stage cluster sampling. The participants responded to measures including Situational Coping Strategies Brief Questionnaire (SCSBQ-28), Ryff Psychological Well-being Scale (RPWS-18) and Single-Question Life Satisfaction Scale (SLSS-1). In the following, 47 participants were identified as incomplete and outlier data. Therefore, the final sample of the study was 613 participants. The results confirmed the 14 factors of the of situational coping strategies brief questionnaire. Convergent and divergent validity were also reported regarding the dimensions and the whole questionnaire with psychological well-being and life satisfaction. Cronbach's alpha of dimensions between 0.63 and 0.86 and the whole questionnaire was calculated as 0.76, which is good. Therefore, researchers and clinicians can use this questionnaire in scientific studies and clinical investigations, considering the fourteen dimensions, comprehensiveness, and shortness of this tool compared to similar tools while being comprehensive.

Ethical values are a subject of academic and public interest. The aim of this study was to investigate the psychometric properties of the Ethical Values Assessment (EVA). The study population was all students studying at the University of Tehran in 1400-1401, of whom 422 participated in the study. The sample size was determined using Cochran's formula. Participants responded to the Ethical Values Scale (Padilla-Walker & Jensen, 2016), Self Perception Profile for Children (Harter, 1989), Religious Commitment Inventory (Worthington et al., 2003), and the quality of relationships inventory (Pierce et al., 1991), which were provided to them online. The analyzes were performed with SPSS22 and Amos22 and in several steps including item analysis, exploratory factor analysis, confirmatory factor analysis, reliability and convergent validity. Results: The results of item analysis showed that all items are sufficient. Exploratory factor analysis led to the extraction of three factors, which were (Based on eigenvalue): ethics of divinity, Community and autonomy. The second-order confirmatory factor analysis also confirmed the three-factor structure along with a general factor of ethical values. The convergent validity of this questionnaire and the total reliability and the reliability of the factors also were appropriate. The questionnaire for measuring ethical values in the Iranian student community has good reliability and validity; Therefore, it can be used as a valid tool to measure ethical values in students.

This study was conducted with the aim of examining the gender differential item functioning of the English language items of the master psychology series exam using the methods available in the context of cognitive diagnostic models. The research sample included 2,455 female applicants and 919 male applicants who attended the Master of Psychology series exam in 1396. The G-DINA cognitive diagnostic model was fitted with data. DIF of the questions were examined with three methods: the Wald test, the likelihood ratio test and the revised likelihood ratio test. The results of these three methods had a moderate agreement on DIF detection. Based on the results 16 questions had DIF. Most of the questions had uniform DIF in favor of men. Questions that had non-uniform DIF, for the dominant applicants were in favor of men and for non-dominated applicants were in favor of women. It is recommended that additional studies be conducted to investigate the existence of the bias and the cause of the DIF.

The aim of this study was to identify the psychometric properties or indicators of the Mental Toughness Scale for Adolescents by McGowan et al. (2016) and examine its relationship with academic procrastination, generalized anxiety, and math anxiety using path analysis. The research sample consisted of 455 high school students in Zanjan city, Iran, who were selected using cluster sampling. Participants completed the relevant scales through in-person administration. Data analysis was conducted in two phases and employing factor analysis and path analysis statistical methods. In the first phase, the psychometric properties of the Mental Toughness Scale were examined. The results revealed that a six-factor solution, in line with the proposed six dimensions of Mental Toughness Scale (challenge, commitment, control over life and emotions, and self-confidence in abilities and interpersonal relationships), provided the best fit to the competing models. Additionally, the overall internal consistency of the scale was satisfactory, with a Cronbach's alpha coefficient of 0.81. In the second phase, the direct and indirect effects of Mental Toughness on generalized anxiety, math anxiety, and academic procrastination were examined using path analysis. The findings indicated that Mental Toughness has a direct impact on generalized anxiety, math anxiety, and academic procrastination. Moreover, Mental Toughness has an indirect effect on academic procrastination and math anxiety through the mediating role of generalized anxiety. The implications of the study's findings for schools and educational environments, as well as suggestions for future research, were discussed.

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.
