Numerous research have attempted to examine how teachers’ interpersonal behaviors are relevant to variability in students’ emotions, behaviors and cognitions within the Physical education context, that most of them have been based on contemporary motivational theories, including self-determination theory. The purpose of this study was to determine the validity and reliability of the Persian version of the Physical educator’s Interpersonal Behavior Scale (IBQ-PE) with high School Students. The method of the current research was descriptive and correlational. For this purpose, 536 first- and second-year high school students with an age range of 13 to 17 years completed a 24-question scale of interpersonal behaviors in physical education. First, the correctness of the translation of the Persian version of the questionnaire was confirmed using the open translation method, and then confirmatory factor analysis based on structural equation modeling was used to determine the structural validity of the questionnaire, and Cronbach's alpha coefficient was used to determine the internal consistency. The results showed that the goodness of fit index and comparative fit index are higher than 0.90. Cronbach's alpha coefficient for the scale of physical educator’s interpersonal behaviors and its dimensions was above 0.7 (acceptability index value). Based on the results, the Persian version of the IBQ-PE questionnaire has good and acceptable construct validity and internal reliability, and it can be used as a valid and reliable tool for evaluating physical educator’s interpersonal behaviors with high School Students.

Despite the importance of refereeing judgments and the sensitivity of referees' role in holding sports competitions and the impact of referees' decisions on the outcome of the game, little research has been done on various aspects of the referees' profession and occupation. The purpose of this study was to determine the validity and reliability of the Persian version of the self-efficacy scale in referees.

The present research, was a descriptive-correlational study. For this purpose, 228 referees of team and individual sports completed the Persian version of the self-efficacy scale in referees. First, using the open-translation method, the accuracy of the Persian version of the questionnaire was confirmed, and then to determine the construct validity of the questionnaire, confirmatory factor analysis based on structural equation modeling was used, and to determine internal consistency, Cronbach's alpha coefficient was used. Also, for the time reliability of the questions, intra-class correlation with the test-retest method was used.

The results showed that the goodness of fit index and the comparative fit index are higher than (0.90). Time reliability (0.76) and Cronbach's alpha coefficient for self-efficacy and its dimensions above 0.7 (acceptable index value) were obtained.

Based on the results, the Persian version of the self-efficacy scale in referees has structural validity and internal and temporal reliability desirable and acceptable for referees of team and individual sports and therefore can be used as a valid and reliable tool to assess the self-efficacy of Iranian referees.

The purpose was to determine the validity and reliability of the Persian version of the sport mental training questionnaire (SMTQ).

Participants were 385 athletes (182 females and 203 males; mean age = 35±18) with different levels of skill (Professional and Semiprofessional athlete) in 14 types of individual and team sports. This questionnaire has five scales with subscales were includes of foundation skills (self-confidence, goal-setting), performance skill (activation control, relaxation, refocusing), interpersonal skills (group integration), self-talk, and imagery. The Ottawa Mental skill, group environment, automatic self-talk questionnaire were used to confirm the concurrent validity.

The findings showed that content and displayed validity were acceptable. Cronbach’s αs showed acceptable internal reliability (α=0.82), and interclass correlation coefficient established test-retest reliability of entire questionnaire (0.89) and subscales. The correlation coefficient of all of subscales with the same questionnaire were significant for concurrent validity. Construct validity were confirmed to compare difference between the high and low skill level, female and male athletes. The results of confirmatory factor analysis showed that the adequate fit to the data.

the Persian version of the sport mental training questionnaire can be used as a valid and reliable tool for Iranian sport psychologists and coaches.

The purpose of this study was to identify and validate the indicators and components affecting the International Development of Table Tennis in Iran. From the paradigm perspective, the present study was a type of pragmatism, mixed approach, exploratory-field nature, phenomenological and survey strategy, and applied in terms of purpose. The data collection method was indepth and semi-structured interviews (qualitative section) and a questionnaire. The statistical population of the study was experts from the national tennis teams of Iran, including the coaches of the national tennis teams of Iran, senior managers in the Ministry of Sports and Youth and the Tennis Federation. The coaches of the various tennis leagues, the tennis boards, the staff and experts of the Ministry of Sports and Youth and the Iranian Tennis Federation formed the sample members of the research in a small section. At first 226 initial codes including 13 main categories and 37 pivotal categories regarding the factors affecting the international development of tennis in Iran were counted, totally the number of these codes were 460. The reliability coefficient of qualitative research re-coding was calculated to be 0.84. The apparent and content validity in the form of CVR and CVR forms was approved by experts and the validity of the research questionnaire after performing the exploratory analysis process. Fit of the model with SRMR calculation equal to 0.066 which showed the optimal fit of the model. Economic factors (0.503), social factors (0.438), infrastructure development (0.43) and technical and specialized factors (0.44), motivational factors (0.373), media factors (0.518), the nature of tennis (0.004) ), Talent identification (0.497), managerial factors (0.530), government and governance (0.458), educational institutions and development of public sports (0.472) as indicators and components affecting the international development of tennis are discovered and validated in which all were reported to have high and medium quality upwards with Q2 calculation

The present study aimed to investigate the validity and reliability of the Persian version of the mental training questionnaire in sport. The research method is applied and development tools which the method of data collection was field research. For this purpose, 242 athletes of various sports have completed the questionnaire of Behnke et al (2017). Confirmatory factor analysis based on structural equation modeling was used to determine the structural validity, and the internal consistency and concurrent reliability of the questionnaire were assessed using Cronbach's alpha coefficient. The results showed that the three-factor structure of mental skills (fundamental, performance and interpersonal skills) and the two-factor structure of mental techniques (mental imagery and self-talk) have a good fit. Cronbach's alpha coefficient was more than 0.7 for the whole questionnaire and five components, which shows the internal consistency of the questionnaire. Thus, can be used from mental training questionnaire in sport for evaluating mental training in Iranian athletes.

The purpose of this study was to Psychometrics of the Qasemi's Seven-Module Communication Skills Questionnaire with the physical education students of Payam-e-Noor University. As a field study aiming at research development, we used the descriptive-survey methodology. The statistical population consisted of the undergraduate physical education students of Payam-e-Noor University of Iran (2016-17) (N=1150). Based on the Krejcie and Morgan's sample size determination table, the required sample size was determined to be 290 individuals, where finally considering the likelihood of dropouts, 300 accessible individuals were non-randomly selected as the sample to complete the research instrument. A researcher-made seven-module communication skills questionnaire was used for data collection. After confirmation of the face and content validity of the questionnaire, the construct validity was assessed through a confirmatory factor analysis. In this study, observation was identified as the seventh skill in a set of communication skills including speaking, listening, reading, body language, use of modern and daily communication tools, and writing skills. Based on the Goodness of Fit Indices (GFI) of 0. 909 and the Comparative Fit Index (CFI) of 0. 921, the model has a good fit. The confirmatory factor analysis showed that the writing skill had the highest priority with 0. 782 and the listening skill had the lowest priority with 0. 384 among the seven communication skills. Finally, it is recommended that the validity of this questionnaire also be examined in other communities to warrant a wider application.
