The purpose of this research was to construct and validate of the parent support scale for physical education. This research was mixed (qualitative and quantitative methods). In the qualitative section, a questionnaire with 29 questions was compiled by examining the theoretical foundations and literature, holding focus meetings, and interviewing 6 experts in the field of PE and educational sciences. The quantitative part of the research consisted of 3 stages. The first stage was distributing the questionnaire among 10 specialists to check the face and content validity, and conducting an initial pilot on 90 people. In this stage, one question was deleted. The second stage was to perform Exploratory Factor Analysis (EFA) and the extraction of 5 factors and remove 2 questions. The third stage was to perform Confirmatory Factor Analysis (CFA) and examine convergent and divergent validity and composite reliability. The research tool in the qualitative phase was interviews with the members of the focus group and in the quantitative phase, a 5-point Likert questionnaire. The participants of the quantitative part were 7634 parents of students from all over the provinces of Iran. After conducting EFA, 26 questions were placed on five factors (attitude into PE, behavioral pattern, interaction with PE teacher, affective support, and hardware support). Also, the findings of the CFA indicated proper fit indices and the model was confirmed. Eventually, it can be stated that the parent support scale for physical education has proper validity and reliability and it can be used in Iran.

The purpose of this study was to validate and validate the online class questionnaire. This study was a correlational study. The statistical population of the present study was physical education students. According to the minimum sample size criterion required for data collection in factor analysis, 384 customers were selected as a statistical sample. Questionnaires were randomly distributed among the samples. Convenience sampling method was used. The standard Bangirt online questionnaire (2004), which was reviewed by Gopal et al. (2021), was used. The questionnaire had four components: quality of instructor, course design, promptfeedback and expectation of students. The scoring method for the questions was based on the Likert five-point scale. The face and content validity of the questionnaire was determined with the help of 10 experts. To analyze the data from Cronbach's alpha coefficient and combined reliability tests to determine internal reliability, from KMO test to determine sampling adequacy, from exploratory factor analysis to identify components and from confirmatory factor analysis to determine structural validity used. The results showed that the reliability of the questionnaire components was acceptable. Regarding the relationship between agents and online classes, the results showed that all agents were able to explain well the concept of online classes; As a result, the internal and external validity of the online classroom model was confirmed. With the approval of the tools mentioned in this study, future researchers can use the current tools to determine students' attitudes toward online classes.

The aim of This study was to design a special physical fitness test for Iran's ground forces. After designing the initial test pattern, its validity and reliability were assessed. Based on the initial model, according to military requirements, three physical fitness tests of Ranger, Armored and Pedestrian forces were designed and the validity of the tests were evaluated. independent t-test was used to determine the structural validity of the initial model of physical fitness test and Pearson correlation was use to determine validity and reliability of the tests.The result showed significant difference in tie of initial physical fitness test between newly enrolled military personnel and the trained military personnel (P≤0/ 043). and significant correlation between the twice times of the initial physical fitness test (r = 84%). The results showed significant correlation between the time of physical fitness test and physical fitness score in ranger (r = -53%), armored (r = -48%) and pedestrian forces (r = -65%). Conclusion The results showed, the primary model due to distinguish difference between newly enrolled personnel from trained has critical validity and due to the appropriate correlation between the two times has apropprate relibility. The results also showed that there is a good correlation and validity between the time of special physical fitness tests and the physical fitness score of Rangers, armored carriers and pedestrians personnel. Therefore becous of this result it seems provided tests have the ability to determine the special physical fitness of Rangers, armored carriers and pedestrians personnel.

Acrophobia is one of the most common fears that one loses thinking and even standing in face of it. The purpose of this study was to investigate psychometric properties of Cohen Acrophobia Questionnaire (ACQ) among Iranian athletes. 225 athletes (75 girls and 150 boys) age ranged 18-50 years old (25.70±6.86 years) and sport experiences of 8.5 ± 3 year participated in this study. The acrophobia questionnaire includes two items of anxiety and avoidance, each containing 20 questions. Prior to the factor analyses, Kaiser-Meyer-Olkin and Bartlett's test of sphericity was used to assess the suitability of the respondent data for factor analysis. Then, a confirmatory factor analysis was used to test the construct validity of the questionnaire using Absolute, Comparative and Parsimony fit indices. It was used the internal consistency coefficient of Cronbach's alpha to calculate the reliability of questions in each subscale. The findings of confirmatory factor analysis showed that the comparative, absolute, and parsimony indices are in acceptable range. Also, the results of Cronbach's alpha test showed that reliability coefficient of anxiety and avoidance subscales were .96 and .97 respectively. the findings of this study indicate that, Cohen acrophobia questionnaire could be used as a reliable tool to measure acrophobia among Iranian athletes.

The purpose of this study was to standardize and determine the validity and reliability of Taekwondo skill tests. By reviewing common skills and surveying elite coaches and athletes in this field, from all available tests, five previously designed by the author were selected to measure main skills. Then, to determine the reliability and content validity of the selected tests, 30 elite male taekwondo athletes of Piroozi Karaj Club were participated in this study and performed these selected tests in two phases by using the age of 20±2 years. Pearson correlation coefficient was used to evaluate the reliability of the tests and based on the results of the competitions and the judgment of the coaches; content validity was determined by using Spearman’s rank correlation coefficient. The results showed that the correlation coefficients of three of the five selected tests were significant (P≤0.05). Use of foot impact speed test (R=0.95 and V=0.75), hand impact strength (R=0.91 and V=0.81) and combined skill speed (eleven strokes) (R=0.88 and V=0.79), was found to be at an acceptable level of trust and confidence. Finally, five value norms have been developed for the three desired tests.

The current research focuses on two dimensions of curiosity, and the purpose of this research is to create a valid and reliable measurement scale for the specific curiosities of sports fans. Therefore, two studies, study number one (including four stages) and study number two (including two stages) have been used to create a special curiosity scale for sports fans. Research data was collected from two data samples (sample number one including 303 people and sample number two 250 people) and from students, scholars, experts and physical education teachers of Kurdistan province. Exploratory factor analysis and confirmatory factor analysis were used to analyze the data using Imus software. Finally, three factors consisting of 15 questions were obtained for the final scale. Factor one (specific information, 9 questions), factor two (general information, 3 questions) and factor three (information about sports facilities and facilities, 3 questions). The specific curiosity of the sports fan has the potential to help us better understand why and how fans become loyal sports fans. Also, it can affect different fans and non-fans and can be combined with previous research and help to better understand the behavior of sports fans. The existing study is an important step to better understand fan-specific curiosity and its impact, but more work is still needed to achieve a full understanding.

The purpose of this study was  constructing and validating of purposeful classroom management questionnaire in virtual education. The statistical population included students of public and Payame Noor universities in Tehran. Convenient sampling method was used and sample size according to Morgan table for unlimited communities was equal to 384 cases. Researcher-made purposeful management questionnaire and the Dehghanizadeh and HosseinChari Academic Buoyancy (2014) were used for data collection. Exploratory factor analysis and first and second order confirmatory factor analysis were used to analyze the data. The content validity of the questionnaire was confirmed based on the views of experts and the criterion validity was confirmed based on the correlation coefficient with Academic Buoyancy. Exploratory factor analysis showed that the purposeful classroom management questionnaire have four basic components. First and second order factor analysis indicated that the four-dimensional structural of purposeful classroom management were valid. As a result, in a situation where face-to-face education is challenged due to crises such as epidemics, natural disasters or air pollution and teachers are forced to teach virtually, measuring the dimensions of purposeful classroom management and Receiving corrective feedback based on it can be a practical tool to improve learning outcomes.

This research aimed to design and standardize the bodily-kinesthetic intelligence assessment questionnaire in Iranian society.

The current research method was a combination of qualitative and quantitative methods with an exploratory design – an instrument development model. In the qualitative stage, after conducting 12 semi-structured interviews, related categories were collected and after checking the face and content validity, a 36-item questionnaire was designed. In the quantitative stage, the validity and reliability of the researcher-made questionnaire were examined. The statistical sample consisted of 808 teenagers from five provinces of the country who were selected by the multi-stage cluster sampling method and all the subjects completed the questionnaire. To determine the concurrent validity, the KTK3+ motor competence standard test was used, and to check the temporal reliability and consistency, test-retest and Cronbach's alpha coefficient were used.

Through exploratory factor analysis, five factors of physical fitness factors related to health and skill, perceptual ability, non-verbal communication, enjoyment and participation in various physical activities, and learning and experience of motor skills were identified and these five factors explained 51% of the total variance. The results of the confirmatory factor analysis showed that the goodness of fit index and the comparative fit index was higher than 0.90. In concurrent validity, the correlation between the scores of the two tests was 0.51 and Cronbach's alpha coefficients (0.89) and intra-class correlation (0.87) were also obtained.

In general, it can be concluded that the bodily-kinesthetic intelligence questionnaire has a suitable and acceptable validity and reliability, and by using this questionnaire, the assessment of the bodily-kinesthetic intelligence of teenagers is possible.

The aim of this study was to investigate the validation of the Persian version of the Sports Mental Exercise Questionnaire.
The method of this study is a non-experimental research and is one of the instruments of validation research in which the required information was collected cross-sectionally. The statistical population consisted of athletes from East Tehran. The sample also included 400 people who were randomly selected and completed a sports mental exercise questionnaire. The questionnaire consists of 20 questions, two main dimensions (mental skills and mental techniques) and 5 subscales including basic skills, functional skills, interpersonal skills, self-talk and mental training. To assess the validity of the factor constructs, a confirmatory factor analysis was conducted on the basis of structural equation modeling. The Cronbach's alpha coefficient was used to determine internal consistency and the intraclass correlation coefficient was used to determine temporal reliability (at two-week intervals).
  The results show a good fit of the Persian version of the Mental Exercise Questionnaire. Internal consistency and temporal stability were also acceptable.
Thus, the Persian version of Sports Mental Exercise Questionnaire has acceptable validity among athletes and psychologists and researchers can use this questionnaire.

The aim of study was the psychometric of the Persian version of the Learning, Executive, and Attention Functioning (LEAF) scale in athletes. The statistical sample consisted of 252 (female=152) Iranian athletes older than 17 years who were selected using the snowball sampling method via sending an online questionnaire. The research tools, including the LEAF scale for adults (Castellanos et al., 2018) and the Barkley Functional Impairment Scale (2011), were used to examine the concurrent validity. The second order confirmatory factor analysis of the scale was used to examine the construct validity of the model. The obtained results showed that, the model has a good fit such that all domains (i.e., comprehension of conceptual learning, factual memory, attention, processing speed, visual organization, sequential processing, working memory, solving a novel problem, mathematics, reading, written expression) showed a high factor loading or correlation with their main dimensions (p≤0.001). Using Cronbach's alpha, the internal consistency reliability was obtained to be over 0.7 and desirable. The correlation between the scores of dimensions and the scale domains was 0.33-0.89, indicating an appropriate validity. The results of the differences analysis to examine the diagnostic validity showed the score of 4 as the cutoff point. MANOVA showed that athletes are significantly different in executive functions based on the level of competition and these functions improve in athletes by increasing the competition level. As the LEAF has appropriate reliability and validity coefficient among adult Iranian athletes, it is suggested that this scale be used in the future sport researches.

It is essential to become physically literate to develop movement skills, as the knowledge and motivation necessary to lead an active lifestyle. The aim of this study was to determine the validity and reliability of Canadian physical literacy knowledge and motivation questionnaires among 8-10-year-old children in Isfahan.

These questionnaires were translated using the translation–back-translation methodology into Persian and adapted to the Iranian context. A Persian version of these questionnaires was evaluated for its psychometric properties by 384 students aged 8 to 10 in Isfahan city (Iran). The construct validity of the questionnaires was determined using exploratory and confirmatory factor analyses based on structural equation modeling, and the internal consistency was checked using Cronbach's alpha coefficient. The test-retest method determined the temporal reliability of the questionnaires.

Face validity was confirmed by five experts in the field of motor behavior. According to the obtained thresholds, the construct validity was acceptable based on the goodness of fit index. A Cronbach's alpha coefficient greater than 0.85 was obtained for the knowledge and motivation questionnaire as its dimensions. The test-retests within two weeks showed that the intragroup correlation coefficients for all five components were acceptable for both boys and girls.

Based on the results, the Persian version of Canadian Physical Literacy Knowledge and Motivation Questionnaires for 8-10-year-old children had good validity and reliability. Therefore, it is appropriate to use these tools to measure the children's physical literacy in Isfahan city.

The purpose of this study was to investigate the psychometric properties of the Persian version body and fitness-related self-conscious emotion questionnaire (BSE-FIT).

The statistical population of this study consisted of students of Arak University. 473 male participants from Arak University were selected by convenience sampling method and completed a body and fitness-related self-conscious emotion questionnaire. Data were analyzed using confirmatory factor analysis based on the structural equation model, composite reliability, average variance extracted, and convergent and discriminant validity.

The results of the confirmatory factor analysis showed that question one, as a clear indicator of shame, was removed due to its low factor loading. Once it was removed, there are sufficient fit indices for the four initial proposed factors.

These findings provided evidence for the validity and reliability of the 15 questions of this tool.
