The main purpose of this study was to identify the optimum approach to analysis of epistemic data in measuring personality traits. For this purpose, MPLUS software and lavan software package simulate different formats of response scales, and two traditional scoring approaches and Thurston's IRT method were compared in some of the most important psychometric outcomes. Overall the findings of the study indicated that the Thurstonin IRT approach performs better than the traditional scoring approach in accurately estimating actual scores, criterion validity, locating a person on the attribute continuum. Also, the research findings showed that the average correlation between estimated scores and actual scores for all three correlation coefficients (0, 0.25 and 0.50) in Thurstonian Item Response Theory is higher than the scores obtained from the classical method; True for all three correlation coefficients, in Thurstonian Item Response Theory more than classical method scores and mean experimental reliability scores for correlation coefficients 0.25 and 0.5 with classical method are higher than scores obtained by Thurstonian IRT method, but for coefficient The mean correlation of the mean scores of the Turestonian IRT method is higher than the classical scores. The findings also showed that the difference between the two tests, both Classical and Trestonium IRT, was significant for both the 48 and 96 questions, and the correlation between estimated scores and actual scores in the Thursetonium IRT method was more than the classical method.

The present study aimed to investigate the psychometric properties of fair classroom assessment Rubric based on Item-Response theory. For this purpose, a sample of 511 students of the University of Tehran was selected by the available sampling method and answered Rubric questions. At this stage, to determine the application of unidimensional or multidimensional models, DETECT and parallel analysis methods were used. The results of both methods rejected the unidimensionality of the data and the results of the parallel analysis showed the extraction of three factors from the data. Also, the comparison of unidimensional and multidimensional model fit indices including log-likelihood, likelihood ratio, Root Mean Square Error of Approximation and comparison of Bayesian and Akaike information criteria confirmed the better fit of the multidimensional model for the data. Thus, due to the polytomous of the answers to the questions, the multidimensional graded response model was used to estimate the parameters of the questions. The reliability of each of the subscales of procedural fairness, nature of assessment and interactional fairness were 0.85, 0.69 and 0.63, respectively. Estimation of the discrimination parameters ranged from 1.048 to 5.802, which showed that all the questions performed well in the discrimination of the upper and lower levels of the fair classroom assessment, and after controlling the false discovery rate, the S-X2 statistic showed a good fit of all Rubric questions. In general, the results of this study show that the developed Rubric has appropriate psychometric properties to evaluate the quality of fairness in the classroom assessment.

The present study has been conducted with the aim of designing and validating the Scale of Iran handball development strategies. to conduct this research, has been used a combined research method. the statistical population of the study was all managers and staff of the Handball Federation, experts and university professors, managers, coaches, active and retired adult players of the national team and all referees of international level and Premier League with a statistical population of 200 people. 14 people were selected by purposive sampling and in the quantitative section, 130 people were selected by convenience sampling method based on Morgan table. In order to collect data, a semi-structured interview was used in the qualitative part and a researcher-made questionnaire was used in the quantitative part. The validity and reliability of the research instrument was evaluated and confirmed in both qualitative and quantitative sections. For data analysis in the qualitative part, was used the Grand Theory and in the quantitative part, was used the confirmatory factor analysis method. The results of the qualitative and quantitative part of the research showed that the tool developed for Iran handball development strategies consists of five concepts with 17 components. Also, the results of confirmatory factor analysis showed that the developed research tool has a very good fit. Finally, the questionnaire designed in this study can be used as a suitable tool to assess handball development strategies in the federation, delegations and handball clubs.

Past research has shown that compassion fatigue is seen in parents of children with special needs. however, there is no suitable tool to measure it for this group. The aim of this study was to Development and evaluation the psychometric properties of the Compassion Fatigue Scale in mothers with children with special needs. The research method was descriptive. The study population consisted of all mothers of students with special needs in Arak city in the academic year 1399-1400. 171 mothers who met the inclusion criteria were selected by convenience sampling method. In addition to the Compassion Fatigue Questionnaire, the Depression, Anxiety and Stress Scale (Lovibond and Lovibond, 1995) was used to collect data. Pearson correlation coefficient, exploratory factor analysis, confirmatory factor analysis and Cronbach's alpha were used to analyze the data. The results of exploratory factor analysis and the correlation coefficient of the questionnaire factors with its total score showed that the compassionate fatigue questionnaire has construct validity. Also, the predictive validity of the questionnaire was confirmed (r = 0.61, p <0.001). The retest results confirmed the reliability of the questionnaire (r = 0.70, p = 0.001). The construct validity of the questionnaire was also confirmed by confirmatory factor analysis. Also, the internal consistency of the questionnaire, which was examined with Cronbach's alpha, was desirable (0.78). Therefore, the Compassion Fatigue Questionnaire has sufficient validity and reliability to assess the compassion fatigue of mothers with children with special needs.

The purpose of this research was to construct and validate the family intelligence questionnaire. This research was practical and tool development type. The statistical population for the preparation of the tool includes parents and students of the fifth grade of elementary school in Kermanshah who were studying in 1400-1401 and their number was reported 1000 according to the report of the Education Organization, which was a targeted sampling with inclusion criteria. (Families that scored high in the research tool including Epstein Family Function and the age of entering the research is 12 to 65 years old) 40 people were selected until theoretical saturation and were subjected to in-depth interviews, and in the second part of the statistical population to evaluate the validity of the questionnaire, including professors of psychology and counseling 15 people were selected with the entry criteria of having a doctorate degree and having at least 5 years of family-related work experience up to theoretical saturation. To determine the face validity of the tool, it was first examined among 30 families of the community, then exploratory factor analysis, first and second order factor analysis was used to confirm the research data, and Cronbach's alpha was used to measure its reliability. The findings showed that in terms of the factor structure of the 30 items of the questionnaire, it can be reduced to the components of communication skills, common goals and strategies, cohesion, spirit of effort and foresight, ability to solve problems and desire for group knowledge, as well as the results of confirmatory factor analysis. It showed that the six-dimensional model of family intelligence has a good fit and Cronbach's alpha coefficient was reported as 0.972. The coefficients in all components are higher than 0.7, so it can be said that the questionnaire has good reliability.

The purpose of this study was to investigate the validity and reliability of the wisdom questionnaire. The population was all the citizens living in Hamadan. in doing so, 440 individuals were selected by convenience sampling procedure. Then, in order to collect data, a researcher-made questionnaire was administered to the participants of the study. The results of factor analysis showed that 58 items from 121 items were eliminated and the opening of the experience was removed from 9 dimensions and 63 items showed high factor loading. Findings indicate that 8 dimensions of the questionnaire had a total variance of 41.81%. Cronbach's alpha reliability coefficient and the test-retest of the wisdom questionnaire were 0.85 and 0.87, respectively, which indicates an acceptable level of reliability. Therefore, coordination between dimensions with total score is acceptable. The validity and reliability of the researcher-made questionnaire are at the acceptable level and indicates that the questionnaire is good enough.
