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 major aim of this research was to investigate the precision of the up parametric statistics to detect common response styles in polytomouse data. In the present study, five-choices data was simulated with 25 replication according to a fully-crossed design based on Partial Cradit Rasch model. The design included foure types of response styles ;Extreme responding positive, negative, acquiescence and midpoint responding, in four -different situations ; Sample size, test length, percentages of aberrant-responding examinees and percentages of aberrant items was investigated. precision of the Up statistic was high to detect the response styles in all situations respectively; ;Extreme responding negative, positive, acquiescence and it was possible to distinguish between the compatible and aberrant response patterns with the highest precision in these response styles,except to detect the midpoint responding was less precision, in some situations. The Up parametric statistics has high sensitivity to detect common response styles in non-cognitive multiple choice data and it is suggested that be used this statistics to detect of the response styles of extreme responding negative, positive, acquiescence .

Assessing psychological characteristics in applying and choosing of the teachers of preliminary schools is one of the important problems of education system and it has got a major role in qualifying education system and mental and spiritual health of the students. In this research, the issue has been surveyed in three psychological dimensions. The methodology is exploratory qualitative and the analysis approach is coding. Its population consists of scholars of education, its sampling is purposeful and interviews are semi-structured. The findings express psychological characteristics of teachers; cognitive dimension consists of analysis power, tact, creativity, innovation, high IQ and powerful memory. Emotional dimension includes cheerfulness, good temper, interest in teaching, emotional stability, humility and modesty, fairness. Personality consists of honesty, responsibility, tolerance, adornment, class management, purity, high social interaction, positive thinking, self-respect and critical thinking. Over all, this research shows that psychological characteristics of teachers are the essential factors in promoting their professional proficiency. The applied outcome of this research will be a model for applying and choosing of the teachers of preliminary schools.

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 main goal of this research was to apply the multi-level in determining the role of metacognitive components associated with drug abuse among adolescents of Kerman Province. The method used in this research was correlation type. In order to conduct this research 1000 school students of Kerman Province have been selected by using multistage cluster sampling method. For data collection in this research, ZARGAR drug addiction preparation Questionnaire and Wels’s Metacognitive Questionnaire (MCQ30) have been used. The results of multi-level approach using One-way random effects Anova showed that the four components (positive beliefs about worries, negative beliefs about worries, low cognitive trust and cognitive self-awareness) explained about 49% of the variance of addiction tendency at school level. Moreover, the random intercept model explained 12% of the student-level variance of drug abuse tendency. Here, the significance of qi-square with the value of 37.983 at the significant level (P <0.0001) reflects the significant change of the null model and model 1. In response to the question that how much the relationship between the tendency to drug abuse and student-level components is similar among schools, a comprehensive model with both student-level and school-level variables (model 2) was used. In model 2, the results showed that at the school level, the mean of positive beliefs and cognitive self-awareness about drug abuse tendency have a significant relationship, but the mean of cognitive trust and negative beliefs has not a significant relationship with the tendency to drug abuse. At the students level, there is a significant relationship between cognitive trust and negative beliefs with drug abuse tendency (P <0.01). In total, it can be said that for variables related to samples with a nesting nature, it is necessary to use all levels in data analysis.

Background: Educational success and determining the effects of personal and environmental factors on the construct is among the most important concerns of educational systems that guarantee the success of the educational consulting procedure. Aim: This study was aimed at designing and evaluating a model for educational success including personal and environmental factors, determining their importance and comparing them in terms of the student’s majors. Method: The design of the study was ex post-facto and the population of the study consisted of all of the students studying at high schools of Yazd. Using random cluster sampling method 550 students were selected. The sample were administered Major Choice Success Questionnaire, Myers-Briggs Type Indicator, Strong Interest Inventory and Multiple Intelligence Test. Data Analysis was done using structural equation modelling. Results: The results indicated that all five factors (interests, personality, intelligence, educational performance and environmental factors) had meaningful, direct impact on educational success. Interest played the most important role and environmental factors were the least important component. Moreover, educational background, interest and multiple intelligence were the most important factors in empirical science and mathematics major. Conclusions: For counseling purposes the role of personal and environmental factors in each major should be considered. Keywords: causal model, educational counseling, educational success.
