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.

Marital silence is one of the things that can be related to divorce. Marital silence is to refrain from expressing opinions and expectations about marital problems and passively accepting conflicts and suppressing emotions in themselves. Measuring marital silence is important due to the use of reliable and reliable instruments and in view of the increasing rate of divorce in Iran. This study was conducted with the aim of building the validity of marital silence questionnaire. The present study is a correlation study. Data were collected using a researcher-made questionnaire. The statistical population of the present study included couples referring to the courts and counseling centers of Kermanshah city. Among the target population, 280 were selected by random sampling method. The research instrument was a 36-question questionnaire. The data were analyzed by exploratory factor analysis and using the WEYMAX statistical software. The first component (communication skills) has the highest correlation with other components, and the highest correlation between the first components (communication skills) with the second component (fear of exposure) with the correlation coefficient is 0.711. Other components (doubts and distrust, interest in the spouse, cultural and educational obstacles and children) have high and significant correlations. The result of marital silence questionnaire showed that it has good reliability and validity. The questionnaire can also be used in consultation with clients and in clinical trials to measure the concentration of people.

The purpose of this study was construct and validate a questionnaire to measure personal epistemology in children. Accordingly, the 44 question with Likert scoring method was designed to have three options. Face and content validity was assessed through the survey of 10 experts and its reliability, through the implementation of 50 students to retest interval of one month, was calculated 0/72. Then, the questionnaire was administered on 472 students (217 males and 255 females) and using factor analysis with varimax rotation method revealed five factors with higher eigenvalues: simple knowledge, certain knowledge, source of knowledge, product of knowing and justification of knowing. In order to determine validity and reliability of the scale respectively, confirmatory factor analysis and Cronbach alpha coefficients were used. Results of Confirmatory factor analysis showed a good fit to the proposed five-factor structure. Also, the total score for internal consistency through Cronbach’s alpha, was 0/85. According to the results, the scale has acceptable reliability and validity and can be used as an applicable instrument in assessing personal epistemology in children.

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.

The present study aims to prepare and standardize a teenagers' gender identity questionnaire for 15-18 year-old teenagers of Tehran city. The questionnaire included 91 questions measuring four scales, including successful identity, premature identity, serotinous identity and troubled identity. 580 high-school students (454 females and 126 males) of Tehran city in the school year 2010-2011 were randomly selected as the sample volume. The construct validity of the questionnaire was assessed by factor analysis of main components and varimax rotation, and four factors were derived from the questionnaire. Moreover, Bennion and Adams' identity status measurement questionnaire and Bem's sex role questionnaire were used to measure the criterion validity of teenager's gender identity questionnaire. The validity coefficient of the questionnaire and its scales was determined by Cronbach's alpha coefficient to fluctuate between 0.73 and 0.82. After the marks received by male and female students were compared, the questionnaire norms for each scale were calculated and recoded on the basis of T and Z scaled marks.
