purpose: This study aimed to assess the validity and reliability of the "Mental Talent Identification Questionnaire for Athletes with Disabilities." Method: This descriptive, cross-sectional survey encompassed 367 athletes (194 women and 173 men) participating in the December 2024 Talent Identification Festival organized by the Sport Federation for the Disabled Persons. Exploratory factor analysis utilizing the principal components approach with varimax rotation was conducted to evaluate validity, and Cronbach's alpha coefficient was applied to ascertain reliability. Findings: The KMO index was 0.872, and Bartlett's test yielded a significant result demonstrating the appropriateness of the data for factor analysis. Preliminary exploratory factor analysis identified six components with eigenvalues exceeding one, together accounting for 55% of the total variance. Five principal variables (self-confidence, resilience, Goal Setting, competitive motivation, and commitment) were kept based on factor loadings and statistical criteria. The Cronbach's alpha coefficient for the complete questionnaire was 0.807, indicating satisfactory reliability of the instrument.Conclusion:The findings demonstrate that the Mental Talent Identification Questionnaire for Athletes with Disabilities exhibits suitable psychometric features and can function as a valid and reliable tool for evaluating mental factors pertinent to talent identification in this demographic.  

The present research was conducted with the aim of improving economic governance in the country's sports based on marketing factors. The participants in this research consisted of individuals with expertise in the field of sports economics. The data collection tool used in this research was semi-structured interviews. To analyze the qualitative data, thematic analysis was employed. The results of this research indicate that in the context of specialized and human facilitators aimed at enhancing economic governance, the main concepts identified include attention to global structures in sports, scientific processes, supportive systems, and managerial systems. In total, 21 components were identified for improving economic governance in the country's sports based on marketing factors, concerning the specialized and human facilitators aimed at enhancing economic governance. Moreover, in terms of foundational, structural, and organizational capabilities concerning the objectives of economic governance, the main concepts identified include expanding penetration rates, building trust, budgeting, and social incentives in sports. A total of 16 components of economic governance in the country's sports, based on marketing factors, were identified. Additionally, regarding the quality of communications in achieving the goals of economic governance, the main concepts included inter-sectoral cooperation, creating a social economy, and informational aspects. In total, 12 components of economic governance in the country's sports, based on marketing factors, were identified in relation to the quality of communications in achieving the goals of economic governance.

Objective : Given the growing elderly population in Iran and the relationship between physical literacy and health, assessing physical literacy in this population is important. However, there are limited studies on the assessment of physical literacy in the elderly. The present study aimed to examine the cross-cultural validity of the Persian version of Senior Perceived Physical Literacy Instrument (SPPLI). Method: At first, the translation/back translation process and content validity were carried out through the Content Validity Index (CVI) with opinion of five experts. Subsequently, concurrent and construct (age differences and convergent) validity, and internal consistency were examined in a sample of 78 older adults (aged 60–90 years) randomly selected from nursing homes and physiotherapy centers in Qazvin. Construct validity of the SPPLI was assessed by comparing age-related differences and its correlation with age and its convergent validity with the Physical Activity Scale for the Elderly (PASE) and the short-form Falls Efficacy Scale-International (FES-I) and concurrent validity was evaluated through the its relationship with the Senior Fitness Test (SFT) as a measure of actual physical literacy. Results : The CVI results confirmed the content validity of all SPPLI items. The results of Mann-Whitney U test revealed no significant difference in perceived physical literacy between the two age groups (p = 0.42). Spearman’s correlation between total scores of SPPLI and age was weak and non-significant (r (78) = 0.123). The Spearman correlation coefficients of SPPLI with total scores of SFT, PASE, and short FES-I were 0.501, 0.452, and -0.001, respectively. Conclusions : The content and concurrent validity of the SPPLI was confirmed, and its internal consistency was good. However, convergent validity was moderate with the PASE and very weak with the short FES-I, while construct validity based on age differences was not confirmed. In conclusion, the Persian SPPLI exhibits appropriate cross-cultural validity.

The present research aimed to explore the role of modern sports technologies in the advancement of athletic sports, employing a mixed-method design. The qualitative phase utilized purposeful and criterion-oriented sampling methods, along with semi-structured interviews, while data collection and analysis were conducted using the thematic analysis method (Brown and Clark, 2006). In the quantitative phase, a questionnaire was developed, incorporating the dimensions and components identified in the qualitative phase. A random sampling method was employed, and Cochran's formula was utilized to determine the sample size, resulting in a determination of at least 384 samples. Ultimately, 356 questionnaires were collected. Descriptive statistics and Friedman's ranking test were employed for the quantitative data analysis. The findings revealed that the development of athletic sports through modern technologies comprises five main components: (1) factors influencing the development of athletic sports through technology, (2) the progression of athletic sports, (3) the challenges encountered in the development of athletic sports through technology, (4) the opportunities for enhancing athletic sports through technology, and (5) the consequences arising from the development of athletic sports through technology.
