Nowadays, the fundamental role of having a purpose for life in physical and mental health has been confirmed. According to victor frankl, presence of a purpose in life gives life a meaning and increases resilience against pains and traumas. The importance of the purpose in life construct reveals the need for a reliable and valid tool to measure it. Crumbaugh and Maholick's purpose in life questionnaire is the first and one of the most applied tools for the assessment of life's purposefulness. The aim of this research is to determine the factor structure of purpose in life questionnaire. The questionnaire was administered on 206 students who were selected through random stratified sampling at Ferdowsi University of Mashhad. Exploratory factor analysis showed that there are two factors "comprehension" and "purpose" and this finding were confirmed by confirmatory factor analysis. Altogether results of this research showed factor validity of the purpose in life questionnaire with a two factor pattern

Research has shown that mental energy is an important factor in many domains, including athletic performance. Therefore, the aim of this study was to determine the validity and reliability of the Persian version of the Sports Mental Energy Questionnaire. The research method was applied and tool development. The study population includedall male and female athletes in Urmia city in different sports; From this population, based on Morgan sample size determination table, 283 athletes were selected by available sampling method. The athletic mental energy questionnaire Lu et al (2018) was used as a research tool. The questionnaire was presented to the athletes after translation into Persian and approval by three experts and then analyzed. To evaluate the construct validity and determine the factor structure of the questionnaire, confirmatory factor analysis based on structural equation modeling was used and the reliability of the questionnaire was assessed using Cronbach's alpha coefficient. The confirmatory factor analysis showed that the six-factor model, the three-factor of the affective components (vigor, tireless, and calm) of AME and and the two-factor of the cognitive components (confidence and concentration) of AME) as well as motivation has a acceptable goodness of fit with the data in the sample of athletes. Cronbach's alpha results above 0.70 for all factors also indicate the appropriate reliability of the Athletic Mental Energy Questionnaire. The findings suggest that this measurement tool with good validity and reliability can be used to assess the athletic mental energy in Iranian athletes

The present study was conducted with the aim of constructing and investigating the factor structure of students' research engagement questionnaire. The research method was survey and the statistical population includes all of the postgraduate students of humanities faculty (Literature and Humanities, Islamic Theology and Science, Sport Sciences, Education and Psychology, Administrative and Economic Sciences) at Ferdowsi University of Mashhad (N=3199). Using Cochran formula, the sample size was estimated to be 343 student. The participants were selected by stratified random sampling. The theoretical model Linnenbrink and Pintrich (2002) was determined as the basis of scale construction. This model includes three components of cognitive, emotional, and leadership engagement. SPSS and AMOS software are used for data analysis. Content validity and confirmatory factor analysis were used to determine the validity of the questionnaire and Cronbach's alpha coefficient to check the reliability. The results showed that the alpha coefficient of the questionnaire was 0.89 and for cognitive (0.80), emotional (0.73) and behavioral (0.76). Content validity of the questionnaire was confirmed by 8 experts of Ferdowsi University of Mashhad (based on CVI) and inappropriate items were removed. Goodness indicators confirmed the fit of the model. According to the research results the research engagement questionnaire had good internal consistency and validity and this questionnaire can be used in research.

Emotions are intimately involved in virtually every aspect of the teaching and learning process and good teaching is charged with positive emotions. Therefore; an understanding of the nature of emotions within the educational context is essential. This study aimed to investigate the Psychometric Properties of the emotions in the teaching Inventory of Trigwell (2012). The research method was descriptive-correlative. Teachers of Ferdowsi University of Mashhad were the research population. The required sample size was determined 280 based on the Cochran formula and participants were selected by the relative class sampling method. The Content Validity of inventory was evaluated by 5 experts based on the CVI Index. The validity was determined by confirmatory factor analysis and the reliability of ETI was confirmed by internal consistency (Cochran`s alpha) and test-retest method. The goodness of fit indexes was confirmed by confirmatory factor analysis (CFA). Also, the alpha coefficient for total size was 0/89 and for subscales was from 0/73 to 0/84. Hence, Results showed that Emotions in the teaching Inventory had acceptable psychometric properties in the sample of university teachers and can be used as a valid scale in studies related to the teaching emotions.

The visuospatial development is one of the most important foundations of development, since it plays the role of the primary function of all learning and communication, and forms the mental representations of the outside world. On the other hand, this development simultaneously contains spatial information and directs all movements in space. Measurement of this development and its various dimensions is vital in the early years of life, since with this information we can estimate the visuospatial capacity of the child and examine the change of this basic capacity during life span. The aim of the present study was to provide psychometric properties for the visuospatial development questionnaire (Harry Wachs, 2014) for use in Iran. A questionnaire was filled out on 348 preschool children in Mashhad that were selected randomly by multistage stratified sampling method and psychometric indices were calculated using statistical software. The findings showed that the questionnaire had a satisfactory content and structure validity and also reliability. The results of the confirmatory factor analysis also showed that the structure of the questionnaire has an acceptable fit with the data. These factors were named in accordance with the main research, body awareness and sense; location of body in space; relation of object to self, other objects and people; conservation of space; Visual-logical reasoning; Representational thought; their coefficients of internal consistency were 0.83, 0.79, 0.67, 0.80, 0.72 and 0.61, respectively. These results show that the Visuopatial development Questionnaire can be used as a tool for measuring the concept of the visuospatial development in Iran.

Two important objectives for measuring the variable in behavioral an dcomplex causal relationships between variables. Beasurement asks about what is measured by observed variables ? and how ew can determine the validity and reliability of variables? The latter responds to this question: since the variables are not directly observable and measurable and only reflected in observed variables with measurement error how complex causal relatonships between these variables can be inferred? How the relationships between latent variables can be measured? In response to these kinds of question are evaluated by the measurement model and that of the second one are evaluated by the structural function model.

Background: One of the important issues related to test anxiety is its impact on students' performance. Further, having a standardized instrument to measure test anxiety is also a significant factor. Objective: The aim of the present study was to determine the psychometric properties of a Test Anxiety Inventory in university students. The purported four dimensional structures of test anxiety (Other-Referenced, Self-esteem, Worry and Blame) were tested. Method: The test anxiety inventory was given to the sample group (n=200). Dimensionality assumptions were tested using confirmatory factor analysis. The trait conception was tested separately for subscales by confirmatory factor models and a principal component factor analysis. Results: The results were supportive of the purported four-dimensional structures a (i.e., acceptable model fit) as well as of the trait conception of test anxiety. Conclusion: The test anxiety inventory has a good reliability and validity, and it can trustily be used for Iranian university students.

his study examined the psychometric properties of a Persian translation of the Fennema-Sherman Mathematics Attitudes Scales among a sample of 400 Iranian high school students. A structural equation modeling strategy via Lisrel 8 (with item parceling procedure) was employed in estimating parameters. In addition, confirmatory factor analysis was conducted to assess construct validity of the nine latent variables, with each latent variable measured by 12 observed variables. The results of this study indicate an acceptable fit between the proposed model and the observed data. From all the 108 items (measured variables), 91 items correlated with their respective factors at a reasonably strong level. In general, the Persian translation of the FSMAS has acceptable psychometric properties. The fit of the proposed confirmatory factor analytic model provides evidence for the scale’s construct validity. The sample used in the present study may be minimally representative of the general population and replication is needed. .
