“…Several theoretical perspectives, such as expectancy-value theory ( Wigfield and Eccles, 2000 ), goal theory ( Elliot and McGregor, 2001 ), and SDT, have been used to examine students’ social skills ( Ryan and Deci, 2017 ), but is SDT the one that has been widely used to look at motivation in both educational and PE settings, what is the context of this research, so this is why we chose it as our conceptual framework. Some academics have suggested using PE and sport environments to help young people improve their social skills (e.g., communicational skills, value-based expressions) in terms of developmental objectives ( Anderson-Butcher and Bates, 2018 ; Nascimento Junior et al, 2021 ) and others also suggest that these abilities will transfer to other life scenarios if they are developed within the environment of PE and sport (e.g., empathy, altruistic behaviors, forgiveness), that fosters social abilities in anticipation ( Turnnidge et al, 2014 ) and protect of antisocial behaviors and social violence ( Rodríguez-Franco et al, 2023 ) when the competitive sport increases. Since among the postulates of the Self-Determination Theory is the promulgation of the relation of motivational constructs and needs to a person’s development and global functioning, including the development of global-life competencies such as social skills ( Ryan and Deci, 2017 ), in this research we wanted to analyzed the relationships between these competencies and Self-Determination Theory main variables in our study context, a sample of disadvantaged Chinese students from rural areas attending PE lessons.…”
