Psychometric Properties of Persian Version of the Movement Imagery Questionnaire-3 for Youth Abstract The purpose of this study was to evaluate the psychometric properties of the Persian version of the The Movement Imagery Questionnaire-3 for Youth. First, the original version of this inventory was translated into Persian and verified with forward-backward standard method, Then, 220 youth athletes (120 girls, 100 boys) who were engaged in Nahavand sports gyms were selected in randomized cluster sampling method and completed the questionnaire (12 questions). Content validity was evaluated through content validity ratio index (CVR), structural validity measured with confirmatory factor analysis by AMOS. The internal reliability of factors and total reliability of scales were also calculated from Cronbach's alpha. So, we can use this scale as a valid and reliable tool for measuring the ability of imagery in three dimensions, motor imagery, internal visual imagery, and external visual imagery. Key words: Mental Imagery, Visual Imagery, Validity, Reliability, Concurrent Validity, Internal Consistency.

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.

In traditional approaches, single-level statistical models were generally used to analyze IEA data. In hierarchical linear models, each level is, however, introduced by its sub-model, and the variables' interrelations are explained in each specified level. The way the variables affect the existent relations in other levels is also determined. The main purpose of this paper is to compare multi-level modeling and single-level analysis techniques and underline the importance of applying the former in analyzing the data extracted from the TIMSS 2007 questionnaires completed by the eighth graders. Due to their nature, the IEA data were analyzed by HLM software as the students were nested within classes, classes within schools, and schools within countries. In the single-level analysis, there was a significant relationship between self- concept, attitude and evaluation at 0.001 level with mathematics achievement (0.48, 0.296 and 0.134, respectively). Furthermore, the results of two-level analysis by one-way ANOVA with random effects showed that these three variables (self-concept, attitude and evaluation) explained 30.10% and 47% of mathematics achievement variance at student and school levels, respectively. The different results of these two analyses demonstrated the importance of using multi-level analyses for nested data like TIMSS. Regarding the nested nature of TIMSS data and the multi-level method used to extract them, the application of multi-level modeling techniques is recommended to obtain more detailed data on the factors influencing the students' achievement.

The purpose of this study was to develop markers of adulthood and achievements of them among students and determine its validity and reliability, based on qualitative research that has already been done in phenomenological method (soleimani & Hejazi,1397). For this reason, 610 students aged 18-29 (317 males, 293 females) from Tehran University were selected by available sampling. After exploratory factor analysis, a questionnaire adapted to the Iranian context for measuring adulthood markers was constructed with 46 items and Cronbach's alpha coefficient of 0.905 in six dimensions: cognitive-emotional mastery, management and regulation of tasks for goal achievement, capacity to play a role in the family, adherence to values, independence, and role transition. The results indicated that there was a developmental stage of emerging adulthood among Tehran University students, their perception of adulthood is more relevant to individual and family skills, and an individual's perception of adulthood is proportional to the acquisition of these skills. Also, the factors of employment, financial independence and the capacity to manage family for men and the capacity of child care for women are more important criteria for adulthood achievement for students

Using different methods and techniques to achieve the best results and create synergies between them can be helpful in many issues. Educational data mining is one of the relatively new fields that can be used to solve educational problems, especially problems in the field of measurement. But before using these methods, it should be as familiar as possible and its problems, disadvantages and advantages should be examined. In this study, the aim is to investigate the technique of nonnegative matrix factorizations and how to determine the number of clusters before implementing the model. The research method is descriptive and the study population is all those present at the entrance exam for mathematics and technical sciences in 1398, of which 5,000 people were randomly selected by the country's assessment and education organization and provided to the researcher. The research tool is math questions and entrance exam geometry. The results of this analysis showed that there is a difference in estimating the number of clusters of math questions, but in the case of geometry questions, the results of all methods were the same. Due to the observed differences, it is suggested that in future research with the help of data simulation, this issue will be examined in more detail.

Backgrounds: Post-event processing involves rumination about perceived inadequacy in a past social situation and has been proposed as an important maintaining factor in social phobia. Aims: This paper investigated the psychometric properties of Post Event Processing Questionnaire (PEPQ) in a student sample. Method: Participants were 460 people (280 female, 180 male) who answered the PEPQ, and 284 of the subjects (198 female and 86 male) completed four Social anxiety related questionnaires including SPAI, SAFE, LSAS-SR and SPS in addition to PEPQ. Also, fifty-five Social Phobic patients answered the PEPQ. The Pearson correlation, Independent sample t-test, Cronbach Alpha and Confirmatory Factor Analysis (CFA) is used as the data analysis method. Results: The Pearson correlation between the PEPQ and the Criteria Scales and between the test and re-test PEPQ score was significant. The CFA replicated the one factor solution for the PEPQ. The Independent sample t-test showed significant difference in PEPQ score between social anxiety group and control group. Also, internal consistency of the PEPQ was acceptable. Comparing with people with self-perspective, participants with observer perspective had a higher score in PEPQ, state anxiety, SPAI, LSAS-SR, SAFE and SPS. Conclusion: Thereupon, it seems the PEPQ is a reliable instrument for assessment of the Post Event processing in Iranian population.

Background: During the past three decades, we have witnessed an outstanding growth in the number of higher education institutions. The growing demand for higher education besides the consequent escalating costs and the restricted financial resources have drawn the attention of the higher education policy-makers to seek ways to increase the efficiency and efficacy of higher education. On the other hand, higher education is criticized for its poor quality and its inconsistency with the market demand. Answering such criticisms requires finding innovative solutions for optimizing the system of higher education. Objectives: The present research intended to answer the following questions in the field of measuring the educational efficiency: What are the obstacles in the way of measuring the educational efficiency of faculty members? In other words what are the challenges of measuring the amount of educational efficiency among faculty members? What is the significance coefficient of the aforementioned challenges and which one has priority over the others? Conclusion: This article was an attempt to review the efficiency factor in the higher educational system in general and to discuss the challenges on the way of measuring the educational efficiency among university faculty members in particular. At the end, some suggestions have been made for the improvement of the measurement of the educational efficiency among the university faculty members.

According to various cognitive models of emotional disorders, anxious and depressed individuals always give priority to negative information rather than positive and neutral ones. Moreover, tests and treatments designed to modify interpretation bias take advantage of limited tools developed in this respect. The Ambiguous Scenarios Test (AST) is also a pragmatic one to measure interpretation bias in clinical situations. Thus, the purpose of this study was to examine the psychometric properties of the Ambiguous Scenarios Test (AST) in Iranian society and formulate it for application in research on interpretation bias relevant to depression. To this end, a total number of 240 university students (61 boys and 179 girls) enrolled at the University of Hormozgan were selected using simple random sampling method. The psychometric properties of the test were similarly examined using exploratory factor analysis, ROC curve, test-retest method with two-week interval, calculation of Cronbach’s alpha coefficient, correlation with mood states, diagnosis of people with high and low moods, and correlation with scores of the Dysfunctional Thoughts Scale. Cronbach’s alpha coefficient for the entire test and the correlation coefficient for the test-retest method with two-week interval were 0.78 and 0.72; respectively. The correlation between the given test and the Dysfunctional Thoughts Scale was equal to -0.57 and the correlation coefficient between group membership and the Ambiguous Scenarios Test (AST) was 0.38. Overall, the results showed that the given test was endowed with proper internal consistency, validity, and reliability and it could also distinguish individuals with negative interpretation bias from those with positive one.

Introduction: The aim of current study was to examine the psychometric properties of the Student Authenticity in relationship scale(AIRS) and examine the relationship between authenticity and fear of intimacy with relationship satisfaction. This scale has 37 items and has been made by Lopez and Rice in 2006. Method: The study population comprised all married clerks in Sanandaj. 207 men and 197 women were selected by multistage cluster sampling method. Factor analysis, Cronbach’s alpha coefficient and Pearson correlation methods were used for Data analysis. Results: Reliability of the (AIRS) by Cronbach's alpha coefficient was 0/773 and re-test coefficient was 0/812. Also, results from convergent validity indicated a significant relationship between (AIRS) and Wood and Linley Authenticity scale. Results from factor analysis showed the Authenticity in relationship scale(AIRS) measure two factors of unacceptability of deception and Intimate risk taking. The second study showed fear of intimacy, unacceptability of deception and Intimate risk taking can predict relation satisfaction. Conclusion: Considering of results the Authenticity in relationship scale has an appropriate validity and reliability and it can be used in further researches on the authenticity in relationship and family field.

To test the reliability, validity and normalization of CTST in Malayer University, a sample size of 340 male and female students was randomly selected. The subjects answered the above-mentioned test under the same condition. The items of the test were translated and adapted to the Iranian culture. The reliability of the test was calculated as 0.689 through the use of Kuder-Richardson, 0.558 through test split half, and 0.652 through test-retest methods. The validity of the test was determined through construct validity (convergent and divergent validities). Correlation of the test score was calculated as 0.64 through the application of Watson-Glaser Critical Thinking Test. Additionally, the correlation of the test with regard to the students' achievement and Cattle anxiety test was calculated as 0.31 and -0.25, respectively, which showed that critical thinking, academic achievement and anxiety are different constructs. Factor analysis of the answered questions revealed that the test includes 15 factors with the Eigen value greater than 1 which justifies 61.42% of the variance in the whole test. It is, however, worth mentioning that within the first three factors that included more than three questions had a factor loud greater than 0.3. No significant difference was observed in the test score mean among the various educational and sex groups.

Purpose: The purpose of this research was to construct and validate the wisdom test based on Iranian components. Method: In this research, a mixed (qualitative-quantitative) method of exploration plan was used. In the first stage (qualitative), a semi-structured interview was carried out with 20 faculty members of Hamadan University of the Humanities (a qualitative research method of phenomenological type). Sampling method was purposeful and based on theoretical saturation. The content analysis method was used to analyze the interview data. In the second stage (quantitative), based on the coding and compilation of the content of the information obtained from the interviews, a questionnaire of 40 questions was formulated. Then, based on multi-stage cluster sampling, 400 people (281 women and 119 men) participated in the study. At this stage, a confirmatory factor analysis method was used to analyze the data (Bartlett and KMO tests and gravel charts). In order to investigate the validity of construct wisdom test, the internal correlation coefficient of the questionnaire and the correlation coefficient of this test with the Ardelt test, were used for content validity of the crest test using Cronbach's alpha coefficient and two-way semi-test and for the reliability of the test, test-retest method was used. Results: The results of content analysis in the first stage (qualitative) showed that wisdom has four components: 1- cognitive component 2- emotional component 3- component of "flexibility and openness to experience" 4- component "Self-transcendence / targeting and searching for meaning." Also, the results of factor analysis (stage II) showed four factors; the first factor (including questions 2-3-4-5-6-8-10-14-15-20-21-32-40) entitled " Emotional dimension ", the second factor (including questions 1-7-9-12-13-16-17-19-22-23-24-25-29-30) entitled" Cognitive dimension ", the third factor (including questions 26 -27-28-35-36-38) as "Dimensional Flexibility" and the fourth factor (including questions 11-18-31-33-34-37-39) entitled "After Self-Processing".

Previous studies have shown that Movement Imagery ability is effective in motor performance and learning in sports and rehabilitation. Appropriate inventory for assessment of this ability in adults (e.g. MIQ-3) development and validated in Iran. However, there is currently no standard tool for using children in Iran. To address this gap, we sought to examine the psychometric properties of the Persian version of imagery ability questionnaire for children (MIQ-C). The statistical population included children from 7 to 12 years old (135 boys, 109 girls) who were selected by random cluster sampling. Results replicated that most items had good discrimination and threshold parameters and high item information values and IRT replicated that all questions have an appropriate coefficient of detection (a) and threshold (b). So the Persian version of the current questionnaire is recommended to measure the Movement Imagery ability to children from 7 to 12 years of age in Persian.

This scale is useful for educational, clinical and research uses.In this research the Persian and localized version of this scale is developed and corresponding standardized, reliability and validity tests are done. 180 subjects were selected randomly from among 5. 7. 9 and 1 I years old children. Weehsier intelligence scale was used for measuring concurrent validity of the Persian version of British Picture Vocabulary Scale. The results are indicative of proper reliability, concurrent validity and diagnostic validity of the Persian version of British Picture Vocabulary Scale. Standardization results showed that the score distribution of 100 is at percentile rank of 50%. Examination of concurrent validity using Wechsler’s intelligence scale indicated the correlation 0.48 between verbal intelligence and vocabulary score. Also, examination of diagnostic validity indicated a significant difference between vocabulary scores of 5, 7, 9 and 11 years old children. Cronbach alpha was used for testing reliability. Cronbach alpha coefficient for 168 items of the Persian Version of British Picture Vocabulary Scale was calculated as 0.84. Based on these findings we can conclude that this vocabulary scale has proper psychometric characteristics for being applied by Persian-speaking children and individuals. Moreover, the larger variance seen in distribution of scores in this research in comparison to standardized samples studied in other countries probably indicates more class differences in the society considered in this research.
