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.

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.

A child's perception of her/his motor competence can play an important mediating role between actual motor competence and physical activity. The aim of this study was to translate into Persian and evaluate the validity and reliability of the Pictorial Scale of Perceived Movement Skill Competence (PMSC ) in 7-10 Years Old Children Ahvaz. The research strategy and design were descriptive-normative and cross-sectional rrespectively. A total of 256 children aged 7-10 years were selected and evaluated by cluster sampling from different regions of Ahvaz. One week later, one subset (n=98) was randomly selected to determine face validity and another subset (n=87) was selected to determine the reliability of test-retest. The research tool was PMSC test. Descriptive statistical methods and confirmatory factor analysis, intra-class correlation coefficient and Cronbach's alpha were used. Face validity was better for object control skills. Cronbach's alpha Results were acceptable in both subtests and the whole test (0.74 to 0.94). Intra-class correlation was high for locomotor subtest (0.90), object control subtest (0.91) and total test (0.94). The hypothesized two-factor model was tested and confirmed. Fit indices had acceptable values. Considering the confirmation of the validity and reliability of PMSC , it can be used with confidence to assess the perceived competence of Ahwaz children's motor skills. Since the samples were only from children in Ahvaz, the results may not be generalizable for all children in Iran. Future studies should evaluate the characteristics of test based on the cultural diversity of other regions.

Lack of physical fitness measurement tools is still felt, especially in different groups, mainly the elderly. Therefore, considering the role and importance of physical fitness measurement in the elderly, the aim of this study was to investigate the validity and reliability of Farsi version of physical fitness measurement tools among elderly. Research method of present study was developmental. Statistical population were Iranian elderly that 250 men and women were selected from Tabriz and Tehran by random cluster sampling. Measurement tools included Short Form (36) Health Survey, Rapid Assessment of Physical Activity, Self-Reported Physical Fitness Survey, Senior fitness test. Data were analyzed using Pearson correlation coefficient, Cronbach's alpha coefficient, and Spearman Brown correlation coefficient and SPSS software version 22. The results showed that concurrent criterion validity was confirmed by correlation between objective and subjective physical fitness measures, and construct validity between some objective and subjective physical fitness factors with physical indices and physical activity. Construct validity was also confirmed between some factors of objective physical fitness and quality of life. The results of Cronbach's alpha reliability for objective physical fitness were 0.69 and subjective physical fitness 0.67. Split half reliability was 0.65 and 0.69. Accordingly, it can be said that the objective and subjective physical fitness measurement tools examined in this study have acceptable validity and reliability in Iranian elderly population. Therefore, we can use these tests in appropriate conditions to evaluate the physical fitness of the elderly alternatively.

Self-report psychological questionnaires are important tools for assessing cognitive and emotional status of athletes. Therefore, the purpose of this study was to investigate the psychometric properties of test of performance strategies (TOPS) among athletes. For this purpose, 209 males (n=125) and females (n=84) national and champions athletes aged 15 to 18 completed TOPS measure. It was used confirmatory factor analysis to test the construct validity of questionnaire and Cronbachchr('39')s alpha coefficient for testing internal consistency of each factor items. The results of factor analysis identified eight subscales of goal-setting, automaticity, emotional-control, imagery, activation, positive self-talk, relaxation, attentional control/negative thinking for the practice and competition. The results of the Cronbachchr('39')s alpha coefficient indicated appropriate internal consistency of subscales items of practice (.70 to .95) and competition (.77 to .88). It seems that this questionnaire is an appropriate tool for measuring psychological skills among young athletes.

The aim of this study was to investigate the psychometric properties of Persian version of exercise dependence scale, prevalence of exercise dependence and some related factors in male and female athletes clubs of Urmia. Subjects of this research were 325 athletes in the sample (206 males; 119 females, mean age 28.06±8 years) various team and individual sports (team sports N= 195, individual sports N=130) in the form of voluntary and available attend in this study. Hausenblas and Downs (2002) exercise dependence scale 21 with seven subscale was the instruments of the study. Exploratory and confirmatory factor analysis was used to determine validity of questionnaire, and Cronbachchr('39')s alpha coefficient was used to determine internal consistency. The results showed that the validity of exercise dependence scale 21 is desirable. Also the results showed that in this study the prevalence of exercise dependence between men and women population is not very different from each other and exercise dependence in individual sports is twice to team sports. Since exercise dependence may exist among a wide range of athletes, therefore, in order to address the adverse effects of this factor, it is necessary to examine the underlying causes and trying to modify it.

The aim of this study was to validation of the Persian version of the scale of enjoyment of physical activity in first grade high school students in Khuzestan province.

Among all of high school students in Khuzestan province who were studying in the academic year 1399-1398, 382 were clustered randomly selected (199 boys and 183 girls). The research tool was the scale of enjoyment of physical activity, the validity and reliability of which were also confirmed. The implementation method was such that using the open translation method, the translation accuracy of the Persian version of the scale was confirmed. For data analysis, confirmatory factor analysis was used to validate the structure and internal consistency using Cronbach's alpha coefficient at a significance level of p≤0.05.

The results of confirmatory factor analysis of physical activity enjoyment scale indicators indicate that the measurement model has a favorable fit and all physical fitness subscales of physical activity enjoyment index had an acceptable factor load and were confirmed. The internal consistency was 0.90 and the internal consistency of the pleasure subscale was 0.82%, communication was 0.78%, competency was 0.72%, improvement was 0.70% and entertainment was 0.74%. It came in handy.

Therefore, the Persian version of the scale of enjoyment of physical activity had structural validity and internal reliability and can be used as a valid and stable tool among students.

Therefore, the purpose of this study was to determine the validity and reliability of Persian version of the Commitment to Physical Activity Scale for Adolescents.

The statistical sample consisted of female students of Arak city who were selected by available sampling method. Participants completed the demographic characteristics questionnaire and the Commitment to Physical Activity Scale for Adolescents (Robbins et al., 2016). Data were analyzed using confirmatory factor analysis and Cronbach's alpha.

The results showed that the goodness of fit index and comparative fit index were higher than (0.90). Also, the results showed that Cronbach's alpha coefficient for Commitment to Physical Activity Scale and its dimensions was above 0.7 (the value of acceptable index).

In general, the results showed that the Persian version of the the Commitment to Physical Activity Scale in Iranian adolescents had acceptable validity and reliability. Therefore, this questionnaire can be used for educational and research purposes.

The purpose of this study was to determine the psychometric properties of Persian version of the sports commitment questionnaire-2. 443 athletes (male: 240 and Female: 203) from 16 team and individual sports, were selected by random cluster sampling. The face and content validity confirmed by sports psychology experts and the correctness of the translation was verified by a specialist in English. The results of the confirmatory factor analysis showed that the general 12-factor model (type of commitment and commitment resources), the 10-factor model (commitment resources), and the 2-factor model (types of commitment) fit well with the data. Intra-class correlation coefficient above 0.76 indicates appropriate temporal reliability and also Cronbach's alpha above 0.75 represents the acceptable internal consistency of the questionnaire. These findings suggest that the sports commitment questionnaire-2 can be used as a valid tool for assessing the type of commitment and sport resources in the Iranian athlete community.
