The aim of this study was to develop a model based on strategic analysis of factors affecting the development of sport participation of veterans, disabled, deaf and blind in Iran. The statistical population consisted of 330 experts in the disabled sport and 220 subjects were selected based on the adequacy of factor analysis sample. A researcher-made questionnaire was used to collect data, and the face and content validity were evaluated and approved by sport management professors (n = 6) and managers (n = 7). Then, Delphi technique consisting of experts based on convenience sampling method (8 subjects) was used to screen and validate different parts of the research. Confirmatory factor analysis test was also used to confirm the construct validity. The reliability of the questionnaire was assessed and confirmed by Cronbach's alpha (0.90). Bartlett test was used for sample adequacy and exploratory factor analysis was applied to determine hidden components in the quantitative tool. Statistical methods of data analysis included descriptive statistics, one-sample t test, Pearson correlation coefficient and structural equation modeling. According to the findings, personal and family, sport, managerial and environmental factors were those influencing the development of sport for all for the disabled. The research model had a good fit in the structural equation modeling (SEM) test; therefore, the model of the development of sport for all for veterans and the disabled in Iran was approved. It can therefore be argued that personal and family factors determine the attitudes of specific strata; if environmental factors are structurally and culturally capable of developing sport participation for the disabled, more talent identification will occur.
