For assessing social and emotional maturity researcher used from emotional maturity scale and Rao's Social Maturity Scale. After eliminating incomplete questionnaires the number of 488 questionnaires were coded and were analyzed by SPSS software by the help of descriptive (mean and standard deviation) and inferential (Parametric and Non-parametric analysis of variances, Pearson and spearman correlation index and multiple regression) statistics. <br />The result of this study showed that doing a sport activity have a significant effect on social (P=0.028) and emotional (P=0.008) maturity. Participation in deferent field of sport activity had a significant effect on some subscale of these two kinds of maturation. Analysis of result showed that the most important variable to predict emotional maturation was championship and the years that person do sport activity and most important variable to predict social maturation was the term of education and living in dorm. <br />Overall these results showed that sport have an effect on social and emotional maturity.The purpose of this study was evaluation the effect of participation in different fields of Sport on social and emotional maturity of female students of Khorasan Razavi province. <br />The statistical population of this descriptive survey was 17-40 years old university girl's students of Khorasan Razavi provinces that by the help of cluster sampling we distributed 488 questionnaires between Statistical populations.

In this regard and to confirm the construct validity of the questionnaire, 197 (106 male and 91 female) athletes with different skill levels (novice, sub-elite and elite) in 10 team and individual sports, selected by random sampling and then completed the questionnaire. For this purpose, the first using a translation - back translation method, content and face validity of Persian version of questionnaire were confirmed by 3 sport psychologists and 3 English teaching specialists. Confirmatory factor analysis (CFA) based on structural equations was used for validation of structure of questionnaire, Cronbach alpha coefficient was used for validation of internal consistency of questionnaire, and intra-class correlation coefficient under test-retest method with 4-week interval was used to study temporal reliability of items. The results showed that the sport mental toughness questioner (SMTQ) had acceptable fit index (RMSEA = 0.06, CFI = 0.94, TLI = 0.92), internal consistency (Confidence = 0.76, Constancy = 0.78, Control =0.72, and the total = 0.76), and temporal reliability (Confidence = 0.74, Constancy = 0.82, Control =0.74, and the total = 0.83), indicating good validity and reliability of the Persian version of sport mental toughness questioner. Therefore, the Persian version of the sport mental toughness questioner (SMTQ) can be characterized as a valid and reliable tool to study and evaluate the mental toughness of Iranian athletes will benefit.the purpose of this study was to determine validity and reliability of the Persian version of sport mental toughness questioner Sheard, Golby and Wersch (2009), respectively.

Participants were 45 autistic children aged 4 to 12 years old from the Autism Center of Isfahan. Thirty seven of them had the criteria to participate in the study which 24 of them were randomly selected, Participants were matched based on movement skills pretest divided in two groups. Movement Assessment Battery for children was used to assess the children's motor skills. First, a pretest was conducted for both groups, then; the experimental group exercised basic gymnastic movements 2 days per week for 24 weeks in 45-minute sessions. Then, a post-test was conducted for both groups. Levine's test for homogeneity of variance and K-S test for normality of the data were used. For data analysis, (ANCOVA) at p 0.05 were used. The results demonstrated that basic gymnastic movements significant improve total motor skills, ball skills and static and dynamic balance. But no significant diference was shown in manual dexterity. The results can be claimed that basic gymnastic movements improve motor skills in children with autism disorder.The aim of this study was to investigate the effects of basic gymnastics movements on motor skills of children with autism disorders.
