The aim of this study was to measure the validity and reliability of perceived motivational climate in sport questionnaire (PMCSQ-2) for Newton and colleagues [2000[. For this purpose, random participants from 553 athletes 13 to 23 years were selected to complete the questionnaire. After applying the translate-retranslate technique, content validity ratio (CVR) and content validity index (CVI) confirmed by 10 Panels (CVR=0.66, CVI=0.97.For determining the construct validity, confirmatory factor analysis (CFA) based on structural equations was used, internal consistency of questionnaire was achieved by Cranach's alpha and Pearson correlation coefficient under test-retest method to study reliability of questionnaire. Results showed that the first model of PMCSQ-2(33 question (, wasn’t able to support the favorable fit and thus eliminated 6 problematic questions. Thereby the final model with 27 questions was included task-oriented climate (TOC) (effort/improvement, important role and cooperative learning) and ego-oriented climate (EOC) (unequal recognition and punishment of mistakes). Hereby, the Persian PMCSQ-2 (PPMCSQ-2) had acceptable fit index (RMSEA= 0.054, CFI= 0.9). Also, Internal consistency was acceptable (TOC=0.827, EOC=0.726 and PPMCSQ-2=0.618) and reliability of PPMCSQ-2(r=0.73) was affirmed. Therefore, PPMCSQ-2 can be used as a valid and reliable instrument to assess motivational climate in the Iranian athletes with the age range of 13 to 23 years.

The purpose of present study was to standardize the measurement tool of beliefs
in advertising through sport. Following the permit was taken from the owner of
the questionnaire (Pyun, 2006), questionnaire by the three-stage translation
method and introductory study performed. Population of the study was all the
spectators that attended in the Azadi Stadium, 342 samples were selected
randomly. 27 items were included in the questionnaire with seven components
(being economic, product information, falsity, materialism, social image and role,
annoying, pleasure). Questions were analyzed by the 5-likert scale. To determine
the formal and content validity of the tool, viewpoints of experts in sport marketing
were used. To determine the structure validity of the tool, CFA was applied by
using LISREL package. Analysis of the structure validity of the tool showed that
items of the questionnaire had an appropriate factor load. The results showed
that the indices of the model had an appropriate goodness of fit2.45¬df=/2x,
RMSEA=0.065, GFI=0.94, AGFI= 0.95 approved the indexes. Cronbach’s Alpha
coefficients of the reliability of the seven components were between 0.70 to
0.730.Given the confirmation of relevant tool in this study; other researchers can
use this tool to measure the customers’ belief advertisement through sport.

The purpose of this study was to determine Psychometric aspects of the Persian version of Infant Movement Motivation Questionnaire (IMMQ) for infants of 3 to 11 months. In this regard, 528 parents and their infants (239 girls and 289 boys) in Tehran were selected as samples through the method of random cluster sampling. For this purpose, first by using a translation - re translation method, IMMQ was translated into Persian by 3 motor behavior experts and 2 English teaching specialists. Confirmatory and Exploratory factor analysis was used for the validation of questionnaire structure; Cronbach alpha coefficient was computed for internal consistency of questionnaire. Also, intra-class correlation coefficient under test-retest method was used to evaluate the temporal reliability of items. The results of Confirmatory and Exploratory factor analysis showed that IMMQ is multifactorial; so that, in total, four factors consisting activity, exploration, motivation and adaptability can explain % 53/32 of the total variance. Moreover, the fit indexes of the extracted model (PGFI = 0.71, NFI = 0.92, RMSEA = 0.078) were favorable and acceptable. Also, Cronbach alpha coefficient (α = 0/93) and intra-class correlation coefficient (r = 0.88) of the Persian version of IMMQ with 27 questions the like of original version, had acceptable internal consistency and temporal reliability. So the results showed that the Persian version of IMMQ can be used for clinical or research purposes as well as an educational tool for parents.

The movement imagery helps to learn various sports skills if persons have a reasonable imagery about how doing that skill and the command be carved on the brain. The main aim of the current study is to investigate the visual and content validity as well as the reliability of the Persian version of the Movement Imagery Questionnaire for Children MIQ-C. The main questionnaire was translated into the Persian by using the Translation-back Translation method. In order to standardize and validate the questionnaire, 10 elites in the field of the motor imagery and sports psychology, filled the questionnaires in order to determine the content validity ratio (CVR) and the content validity index (CVI). After a primitive study, the necessary modifications were applied.The questionnaire reliability was investigated by the test-retest reliability method and the Cronbach's alpha. Results indicated that the CVR and CVI are 0.62 and 0.79, respectively, which confirms the validity of the questionnaire. The reliability was confirmed by the internal consistency method which value was obtained higher than 0.7. For evaluating the ability of children in motor imaginary, a reliable method should be used.According to obtained results of the current work, the questionnaire benefits from a suitable reliability and validity.

The aim of this research was to constructing and validating the questionnaire of the factors influencing the implementation of green productivity strategy in Iran's sport. The present research carried out in a combination (qualitative and quantitative) method. The statistical population of the research in the qualitative stage consisted of 20 environmental experts and sports management professors, and in a quantitative stage consisted of all sports managers, environmental experts and university professors. The sample size was determined by using purposeful judgment available sampling 357 people. Content and construct validity of the questionnaire was confirmed and its reliability coefficient was estimated to be 0.86 .The results of the research identified and introduced seven effective factors (education and research, human resources, culture and attitudes, laws and regulations, control and supervision, management and planning, and physical factors) as effective factors. These factors produced a questionnaire with 39 items that explained 61.77% of the variance of green productivity. Additionally, the fitness indices of the first and second order confirmatory factor analysis supported the structure of the questionnaire. The constructed tool has a functional capability as well as a good validity and reliability. As such, the tool is suggested to be used in the evaluation and management of green productivity of sports organizations.

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 Cronbach'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 Cronbach'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.
