AbstractBackground and objectives:The purpose of the present research was to investigate Theorical model and psychometric properties of Persian version of AEQ were translated in to Farsi research on these areas negleted, may be because of lacking appropriate instrument. In response to this deficit, pekrun and et al(2005) developed a self-report instrument measuring various achievement emotions that students commonly experience in academic setting. The instrument contains scales for measuring enjoyment, hope, relief, anger, anxiety, shame, hopelessness, and boredom in class, learing and test contexts.Methods: First, the AEQ were translated in to Faris. After the pilot studing and resolving the mistakes, the Questionnaire were carried out to a sample group consisting of 300 students who were studying in Islamic Azad university in Tehran. Psychometric properties and Factor analysis were used to analyze the collected data. Results:The results showed that the AEQ scales are acceptably reliable and valid, and most of Questionnaire scale have acceptable Fit with data.

Objective: The present research aims to study the factor structure, reliability, and validity of the Successful Intelligence Scale. Method: Using the multi-stage cluster sampling method, 500 (including 175 female and 325 male) subjects were selected from among public school students in Karaj. Results: The exploratory factor analysis was performed using the principal component method. The results confirmed three factors of successful intelligence (i.e. analytical, creative, and practical intelligence) as well as the principal factor. Reliability of the scale items was examined using Cronbach’s alpha coefficient, and its validity was investigated using factor analysis. Internal consistency of the questionnaire was acceptable, and the Cronbach’s alpha for the subscales was between 0.74 and 0.81. Also, the confirmatory factor analysis results confirmed that the structure of the scale had an acceptable fit to the data, and that the goodness-of-fit index for the model was observed. Conclusion: The results of confirmatory factor analysis were almost close to that of studies done in the original cultural context. Validity and reliability of the scale were also close to that of previous researches. Considering the desirable psychometric property, therefore, this scale is an appropriate instrument for measuring the students’ successful intelligence.

Background: The issue of achievement or non-achievement in the realm of education is an important concern in education systems of all societies. Students and university students’ education achievement is indicative of the extent that the education system has been in setting the goals and satisfying individual demands. Education resilience is an individual variable influencing education achievement. Objective: The present research aims to study the factor reliability and validity of the academic resilience inventory, constructed by Samuels (2004). Method: Two sample populations were involved in this study. The first sample included 300 male and female subjects randomly selected from among public high school students in the city of Boukan, Iran. The second one included 319 male and female subjects who were selected from among Allameh Tabataba’i University students, using cluster sampling method. Cronbach’s alpha coefficient was used to examine reliability of the questionnaire, and exploratory factor analysis, including principal component analysis and confirmatory factor analysis, was performed to confirm factor validity. Results: The evaluation of the first analysis scree plot was indicative of a three-factor solution. Then, to obtain the three-factor structure, the principal component analysis was performed through the varimax rotation. 11 questions were eliminated because they had a factorial load below 0.3, or had significant value or equal load on more than one factor. Finally, the analysis was performed on the remaining 29 questions. Conclusion: These three factors were named according to their comprising content with the following names: communication skills, future orientation, problem-oriented approach, and optimistic orientation. Cronbach’s alpha coefficient for the subscales ranged from 0.63 to 0.77 in the high school students sample and ranged from 0.62 to 0.76 in the university students sample. This shows that reliability of the three-factor model is at an acceptable level.

Background: Executive skills are high-level cognitive skills helping children with their daily activities and learning assignments. Objective: The present paper aims to study the validity and reliability of the Executive Skills Scale for pre-school children. Method: The study was a descriptive research. Using cluster sampling method, 250 subjects (including 150 female and 100 male subjects) were selected from among pre-school children in Isfahan, and their mothers responded to the Executive Skills Scale items. The validity of the scale was evaluated with content validity, item analysis (item–total correlations), and factor analysis. The reliability of the mentioned questionnaire was studied through Cronbach’s alpha and split–half reliability. Results: The results showed that item-total correlation coefficients were significant in all cases, varying from 0.21 to 0.81. (P=0.0001). Moreover, using Cronbach’s alpha, the reliability of the whole scale was calculated as 0.75. Also, the split-half reliability was computed to be 0.80. Conclusion: The results indicated that the Executive Skills Scale is of acceptable psychometric properties to be used for the Iranian pre-school children.

Background: Reliability and validity are important issues in test construction. System approach is a concept with various functions that considers interaction of employed people in different parts of a system. Objectives: The present research aims to study the construct, normalization and validation of the system approach scale in educational planning. Method: It was adescriptive survey research. Using multi-stage cluster sampling method, 483 subjects were selected from among all the principals and teachers in west Mazandaran's high schools and secondary schools. The subjects responded to the researcher-made system approach questionnaire. Results: Using Cronbach's alpha, reliability of the test was computed as 0.981. Factor analysis of system approach items indicated that they explain more than 61.328% of the intended variance. After one varimax rotation, the desirable consistency between items and factors were determined. Then, five factors (including strategic attitude, strategic management, focusing on work environment, realities and objectives, paying attention to requirements, complexities and tasks, and knowledge and information management) were extracted and labeled as the components of system approach to educational planning. Conclusion: Considering the desirable psychometric properties, this questionnaire can be used to measure the system approach adopted by the employees of educational centers, such as the Ministry of Education, and universities. Consequently, it helps to prepare the ground for improving the educational programs and increase productivity of educational systems.

Objectives: The major aim of this research was to introduce Generalizability Theory and its application to estimate the reliability of job analysis data.
Methods: Twenty employees of a state bank certified administrative specialist jobs were randomly selected from among qualified employees. After training, they were given job skills questionnaire to rate the importance of each of the skills for the job of administrative experts to determine.
Results: To estimate the reliability of job analysis data in the framework of Generalizability Theory, a five-step approach was introduced that can be used to estimate the reliability of job analysis data. The steps are: 1- Identify the object of measurement, 2- identify facets of measurement, 3- identify an appropriate measurement design, 4- estimate variance components and their interpretation and 5- identify the type of decision.
Conclusion: It became apparent that the generalizability theory is useful to estimate the reliability of job analysis. It provides the opportunity for job analysis in such a manner that in different situations such as estimating the contribution of each systematic error sources, such as career history, age, and place of work assessors and achieving the desired reliability, it can perform the required activities.

Background:Heller defined familism as a specific from of social organization where the interests of the family group prevail over those of the individual family members.
Objective: The purpose of the present study was to investigate the reliability and construct validity of Familism Scale in undergraduate students of Ahvaz Teacher Training Centers.
Methods: 332 students (156 male and 176 female) of teacher training centers that were selected randomly using the multi-stage sampling method and completed Familism scale and 16 items of cohesion subscale of Family Adaptability and Cohesion Evaluation Scale (FACES-2).
Results: The factor analysis using the principal components analysis and orthogonal rotation (varimax) showed three factors (familial support, familial honor, and subjugation of self for family). Cronbach’s alpha coefficients were for the whole scale 0.73, for extracted factors 0.55 to 0.82, and Concurrent validity coefficient of Familism scale with FACES-2 was 0.21 (P<0.001). Confirmatory factor analysis of three-factor model with one modification index provides a parsimonious fit.
Conclusion: The results of this study indicated that the present scale is a valid and reliable measure for evaluating familism dimensions in students.

Background: Implicit theory of intelligence is one of the newest socio-cognitive strategies proposed in scholastic motivation.
Objective: The aim of the present study is to investigate the validity and reliability of the 14-item implicit theory of intelligence scale (IT IS-14) (Abd-El-Fattah & Yates, 2006) in the Iranian student society. This instrument is used to measure the incremental and entity theories.
Method: The sample in this study includes 350 B.A. students in Ahvaz Islamic Azad University and Masjed Soleiman Islamic Azad University. The data analysis was carried out through the use of confirmatory and exploratory factor analysis, Cronbach’s alpha and Pearson's correlation coefficients statistic methods.
Findings: The Cronbach’s alpha coefficients for the subscale of incremental theory and subscale of entity theory were calculated as 0.82 and 0.74 respectively. To estimate the criterion validity, Dupeyrat and Marine’s scale of implicit theories of intelligence were used, and the correlation coefficients for the subscales of incremental theory and entity theory were calculated at two scales which were significant at the level of 0.001. To calculate the construct validity, confirmatory factor analysis and exploratory factor analysis were applied. The results indicated that the structure of implicit theory of intelligence scale was fit with the data and all indexes of fitness confirmed the model’s fitness. In addition, exploratory factor analysis leads to extract two factors of incremental and entity theories of intelligence.
Conclusion: Given the calculated psychometric properties, researchers can apply this scale applied to investigate implicit theories of intelligence (beliefs about intelligence) in the student society.

Background: Preparing a valid instrument to measure the basic psychological needs in Iranian populations is necessary for research purposes.
Objectives: The aim of this study was to examine reliability, validity, and exploratory factor analysis of a Persian version of the Basic Needs Satisfaction in General Scale (BNSG-S) in a sample of Iranian students.
Method: Five hundred and eighty four students (273 males, 311 females) were participated in this study, voluntarily. All participants were asked to complete the BNSG-S (Gagne, 2003), the Eysenck Personality Questionnaire-Revised Short Scale (EPQ-RS; Eysenck, Eysenck, & Barrett, 1985), Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988), and the Mental Health Inventory (MHI-28; Besharat, 2009).
Results: The results of exploratory factor analysis supported a single general factor of basic needs satisfaction in general and a three factor structure including Autonomy, Competence, and Relatedness. The convergent and discriminant validity of the BNSG-S were supported by an expected pattern of correlations between the scale and the measures of personality and mental health. All correlation coefficients between the mean scores on the BNSG-S and scores of the extraversion, neuroticism, positive affect, negative affect, psychological well-being, and psychological distress were statistically significant. Coefficient alpha estimates of internal reliability were between .83 and .91 for the BNSG-S subscales. Test-retest reliability of the BNSG-S was also calculated at the range of .67-.77. All correlations were statistically significant.
Conclusion: It was concluded that the BNSG-S can be considered as a reliable and valid scale to measure the basic needs satisfaction in Iranian samples.

Academic delay of gratification predicts academic performance, motivation, self-regulation and self-efficacy in students. Due to the importance of academic delay of gratification in teaching-learning processes, there is a need for special tools proportional to the Iranian culture. The objective of this study was to examine the psychometric properties of Persian form academic delay of gratification scale, including reliability, validity, and factor analysis. The population consisted of Iranian high school students from Karaj (N = 600, 326 boys and 274 girls) who were selected based on multistage cluster sampling. They were tested by academic delay of gratification scale and motivated strategies for learning questionnaire. Test- retest reliability academic delay of gratification scale based on the results of two performance tests and its internal consistency by Cronbach's alpha coefficients were calculated and confirmed. To analyze the concurrent validity and to determine the validity factor motivation strategy-learning questionnaire was used, which indicated that concurrent validity is adequate. In addition, results indicated that the separate confirmatory factor analysis (CFA) for the male and female samples showed a goodness of fit with the data. The findings of factor analysis as well as the reliability and validity coefficients were similar to the previous studies conducted in the original culture. Regarding its good psychometric properties, the scale is an appropriate instrument to measure student's academic delay of gratification.

The British Picture Vocabulary Scale (BPVSJI) is one of the most applicable and common scales for measuring children’s language abilities. 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.

The fact that childhood temperament is one of the most important determinants of adults' emotional and psychological disorders makes early assessment of difficult and problematic temperament necessary. Moreover, appropriate tools are needed to attain this objective. The present study seeks to evaluate the psychometric characteristics of ps-TCI in the Iranian preschoolers. A statistical sample of 200 children from five kindergartens in Shahriar was randomly selected through the process of cluster sampling, and their temperament and personality were tested by 18 kindergarten teachers using the Cloninger’s Preschool Temperament and Character Inventory. After fourteen days, the process was repeated, and its validity and reliability were assessed. The reliability was calculated by test-retest, spilt-half and Cronbach's alpha coefficient as 0.89, 0.75 and 0.82, respectively. The validity of the inventory was also investigated by convergent validity and exploratory factor analysis. The results from factor analysis and varimax rotation method yielded seven factors, including cooperativeness, harm- avoidance, novelty-seeking, reward-dependence, persistence, self- direction and self-transcendence which accounted for 59.19% of the total variance. The convergent validity was confirmed by computing a correlation coefficient between the subscales together and with total scale, which was significant between 0.62 and 0.71 (p<0.01). In conclusion, Cloninger’s preschool Temperament and Character Inventory generally proved to be a valid and reliable tool in evaluating the temperaments of the Iranian preschoolers.

Background: The Multidimensional Aptitude Battery (MAB) is a group intelligence test based on the Wechsler Adult Intelligence Scale- Revised (WAIS-R). The MAB is designed for the assessment of a wide range of intellectual abilities of both adults and the16-year old or older adolescents. Objectives: The purpose of the present research was to investigate the adaptation, normalization and the psychometric propertiesof the Persian version of the MAB among the Payame Noor Universitystudent population. Methods :First, the subtests were translated into Farsi. Then, some of the subtest items were adapted to the Iranian culture and were ready to be used. Finally, after the pilot study and resolving the errors, the final subtests were administered to a sample group consisting of 315 students of humanities and basic sciences in Payame Noor University of Tabriz.In this study, the mean and the standard deviation of the subtest raw scores were used to produce the standardized scores (with a mean of 50 and a standard deviation of 10) and then the standardized score conversion chart was formulated. Results: The results of the internal consistency and test- retest reliability revealed that the MAB is adequately reliable. All the subtests had middle and high correlations with Raven’s Advanced Matrices’ intelligence test scores, which showed concurrent validity of these subtests. The correlation coefficients in the multidimensional aptitude subtests were in the range of 0.18 to 0.58. The correlation between the general information, vocabulary and picture completion subtest scores and age was positive and significant, but the correlation between digit symbol, spatial, picture arrangement and object assembly and age was negative and significant. The summary of the regression coefficient results showed that vocabulary subtests were the best predictor of the total score of verbal scale and the spatial subtests were the best predictor of the performance scales and the other subtests were of lower ranks. Conclusion: The results of the study indicated that the Persian version of the MAB is a reliable and valid measurement tool that can be used for academic and career counseling purposes, and basic researches.

Background and Objectives:The main purpose of the present research was to validate the McMaster Clinical Rating Scale (MCRS) among the married men and women who consult the counseling centers in the province of Sanandaj. Methods: The study adopted a correlative design (factor analysis via Tendentious Oblimin Rotation Sort and confirmatory factor analysis). The study sample included 357 subjects who were randomly chosen during two phases (in the first phase, 283 subjects and in the second phase, 74 subjects) from among all the men and women clients in the counseling centers in Sanandaj. The participants completed the McMaster Clinical Rating Scale (MCRS) and the Criterion Questionnaires, and then the data was analyzed using the factor analysis via Tendentious Oblimin Rotation Sort and confirmatory factor analysis.Results: The results obtained from the factor analysis via Tendentious Oblimin Rotation Sort indicated the seven factors of the McMaster Clinical Rating Scale (MCRS), which later fitted the confirmatory factor analysis. The reliability coefficients of the internal consistency including Cronbach’s alpha and split-half were satisfactory for the 60 elements and seven factors (83% and 82% respectively). Furthermore, the discriminating and convergent validity coefficients of the McMaster Clinical Rating Scale (MCRS) were examined by the measurement tools for Communication Patterns Questionnaire(CPQ), locus of control scale(LOCS),self-Differentiation of Self Inventory-2 (DSI-2) and the correlation results for the three criteria are respectively as follows: 46%, 36%, -41%, and -43% which are significant at (P<0001).Conclusion: The results of the factor analysis are consistent with previous findings and considering the validity and the reliability of the McMaster Clinical Rating Scale (MCRS), it can be used in research and clinical environments for distinguishing the normal people from the abnormal ones.

Background: Concept maps usage expanding as an academic achievement measurement tools great a challenge in scoring them. This study introduces three scoring methods of the concept maps tests: (1) relational method that in which a relationship between concepts separately was scored. (2) structural method that based on scores was given to hierarchical organization of the concepts. (3) similarity method that in which a student’s concept map compares with a teacher’s concept map and assign score for each section of the map. Objective: The objective of the present research was to examining the validity and reliability of concept map-based tests scoring methods. critical validity, interpreter reliability and discriminative reliability were used to identify the most appropriate method of scoring. Method: the subjects of the research comprised 105 high school students in Tabriz city who were present in four classes. Results: Results showed that the relational method of scoring has higher quantities of the indicators than other methods. Similarity scoring method has the lowest indices in comparison with two other methods. Conclusion: These findings may have some implications in evaluating students' academic achievement which will be discussed in this paper. .
