The study aimed to construct two measurement scales—one for dialogical leadership and another for sustainable development—in youth and sports forums in Baghdad, and to identify the levels of both variables as perceived by employees. It also examined the contribution and effect of dialogical leadership on sustainable development. The researcher hypothesized that the results of the dialogical leadership scale would be significantly correlated with and positively influence the results of the sustainable development scale. A descriptive correlational approach was adopted, with a population of 1,161 employees from three youth and sports forums in Baghdad (Al-Karkh, Al-Rusafa, and Sadr City). The main sample was purposively selected from the Al-Rusafa Forum, consisting of 431 employees (37.12% of the population). After excluding non-relevant participants, the final sample included 225 employees (19.38%), divided into three subsamples: 10 for the exploratory sample, 120 for scale construction, and 95 for the main application. Data were collected between February 9 and 27, 2025, and analyzed using SPSS. The results showed acceptable levels of both dialogical leadership and sustainable development, confirming their measurable nature in the context of sports management. The findings also indicated that enhancing dialogical leadership positively contributes to sustainable development. The study recommends periodic evaluation of these two variables and involving employees in administrative development programs to strengthen dialogue and promote sustainability in youth and sports forums.
