The aim of this study was to determinate the validity and reliability of the Persian version of the Brief-BES Test in the elderly. The final version of the Brief-BES Test in the elderly was retranslated and developed based on the viewpoints of experts in elderly studies. 100 elderly men and women were voluntarily selected from Hakim Elahi nursing home in Semnan city. The data were analyzed using descriptive and inferential statistics: confirmatory factor analysis (CFA) and Cronbach’s alpha coefficient to examine factorial and construct validity and internal consistency respectively. Findings indicated good fit of the factor analysis model over the Persian version of the Brief-BES Test in the elderly. In addition, the results of Cronbach’s alpha coefficient demonstrated the acceptable internal consistency of this tool. Proper translation and selecting a heterogeneous sample may have contributed to the good fit of the factor analysis model.

Relaxation is a way of improving performance that can generally be classified as physical and mental relaxation. The mental relaxation technique is often named as the technique of mind to the body since the purpose of these techniques is to provide relaxation through the mind. The aim of the present study was to determine the effect a period of relaxation program (body to mind and mind to body) on the performance of semi-skilled football players. For this purpose, 39 players were selected and divided randomly into three groups: progressive muscle relaxation, creative visualization, and control. Before the interventions, a pretest was conducted by the observational method. In this relaxation program, subjects underwent two different types of relaxation after football training for 8 weeks. Data were analyzed using descriptive and inferential statistics, analysis of variance with repeated measures and one-way analysis of variance. The results showed the significant effect of progressive muscle relaxation and creative visualization on maintaining and controlling the ball, accurately passing, accurately taking the ball from the opponent and overall players’ performance. In addition, the athletes who used progressive muscle relaxation had better performance than those who used creative visualization. In general, the methods of the body to mind and mind to body relaxation can each serve as an independent way to improve the performance of athletes, but the implementation of mind to body relaxation, such as the visualization of creativity, is more effective at skills that require more precision and concentration.

The aim of this study was to determine validity and reliability of the Persian version of the Flow in Computer Games Questionnaire so that the flow performance in computer gamers can be evaluated. 400 gamers (237 males; 163 females) were selected by random cluster sampling method and completed the Persian version of the Flow in Computer Games Questionnaire. In the first step, translation accuracy of the Persian version was confirmed through back translation method. Then, confirmatory factor analysis based on structural equations model was used to determine construct validity while Cronbach alpha coefficient was applied to determine internal consistency. Intra-class correlation in test-retest method was administered for temporal reliability of the items. The results indicated acceptable fit indices (CFI=0.92, TLI=0.75, RMSEA=0.062), internal consistency (ɑ=0.75) and temporal reliability (ICC=0.85) for the Persian version of the Flow in Computer Game Questionnaire. The results supported the multifactor structure and 23 items of the Flow in Computer Games Questionnaire. Therefore, the Persian version of the Flow in Computer Game Questionnaire has an acceptable validity and reliability among computer gamers and it can be used as a valid and reliable tool to evaluate the flow performance of these gamers in Iran.

The purpose of this study was to evaluate the effects of progressive motor program on improving motor skills in children with autism. In this quasi-experimental study, 16 subjects (2 girls, 14 boys) who had been diagnosed with autism in the cities of Semnan and Yazd were selected. After they relatively were matched based on age, sex, grade, and the degree and severity of autism, they were divided into the experimental (8) and control (8) groups. The Test of Gross Motor Development-Ed2 were used to assess fundamental motor skills. After pretest by TGMD-2, Progressive motor program was conducted for 30 sessions in experimental group. After 15 and 30 sessions, experimental and control groups participated in the mid and post-tests. Retention test was performed 30 days after the end of the 30th session. Data were analyzed by Variance Analyze of Repeated Measures. The results showed that progressive motor program, with the significance level of P <0/05, had a greater impact on the development of locomotor, object control and gross skills than the control group.
