ABSTRACT
This study analyzes whether the degree of social identity and the degree of emotional connection influence the subjective well-being of individuals that participated in collective acts of support for health personnel fighting against the COVID-19 pandemic. Our sample was composed of 810 participants who resided in Spain (339 women and 471 men) with an average age of 34.22 (SD = 12.56). All of them frequently participated in the acts of support that took place each day of the lockdown decreed by the National Government on 14 March 2020. The results show that the greater identification with the group (the country) and the greater the emotional connection, the higher the scores obtained in subjective well-being. The results also show that emotional connection had a positive effect on emotional subjective well-being, mediated by the social identity activated in the collective act. The results are interpreted from the perspective of social identity that highlights the role played by social identity in influencing health and subjective well-being.
