 	abstract = "Background and rationale: Global economic growth combined with technological advances have driven the rise of virtual teams, characterized by collaboration between geographically dispersed members. Although these teams offer benefits such as cost reduction and increased productivity, they also present challenges, especially related to building interpersonal relationships. Given the importance of understanding how social interactions affect the effectiveness of virtual teams, this study proposes to investigate the dynamics of social identity and leadership in this context.
 Research problem: How does leadership relate to social identity in virtual project teams? Main objectives: To investigate the relationship between leadership and social identity in virtual project teams, and its impacts on extra-role behavior and individual performance of members.
 Methodology: The research adopts a three-study approach:
 Systematic literature review to identify the state of the art on social interactions in virtual teams. Integrative literature review to map measurement scales for these interactions.
 Structural equation modeling examines relationships between leadership and social identity, using data from questionnaires applied to virtual teams.
 Results: The research revealed that leadership exerts a direct and significant influence on the construction of social identity in virtual teams. It was found that leaders with transformational characteristics can promote a greater sense of shared identity, strengthening member engagement and performance. In addition, the research identified that social identity is positively associated with extra-role behavior and individual performance. The measurement instruments adopted demonstrated high reliability, allowing a robust analysis of social interactions and leadership dynamics in the virtual context. The proposed theoretical model was validated, contributing to the advancement of understanding about the factors that drive effectiveness in virtual teams.
 Contributions to Practice: The research provides guidance for managers and leaders of virtual teams, highlighting practices that promote engagement, cohesion, and effectiveness. A technological artifact is also proposed to facilitate the measurement of social interactions, contributing to the management of dispersed teams.
 Contributions to Theory: This study advances the theory of social interactions in virtual teams by exploring the influence of leadership on the construction of social identity. It also contributes methodologically with the use of structural equation modeling, allowing in-depth analyses of causal relationships in virtual environments.
 Originality and Value: This work is innovative in combining multiple methodological approaches to investigating social interactions in virtual teams. It fills gaps in literature, especially in the understanding of social identity and its relationships with leadership and cohesion, offering solid foundations for future research and practical applications.",
