BackgroundSatisfaction and happiness are two widely studied topics in current literature. Human beings need to find happiness. However, for many authors, satisfaction is a prerequisite for happiness. Satisfaction, in turn, can be approached from different perspectives, such as job satisfaction, health satisfaction, and social life satisfaction. This research analyses the relationship between these variables and their influence on proactive social behaviour.MethodsThe present study utilised the European Social Survey, an academic survey conducted across Europe in its round 10, carried out between 2022 and 2023, with a database of 25,311 valid responses. Structural equation modelling analysis conduct using PLS-SEM with the Smart PLS software.ResultsThe results demonstrate a direct and significant relationship between overall satisfaction and happiness and between happiness and prosocial behaviour. Similarly, a solid indirect relationship exists between satisfaction and prosocial behaviour in society. Furthermore, job satisfaction is among the variables influencing overall satisfaction and happiness. However, it is not the most important, with satisfaction with social life being the most influential on satisfaction.Conclusions and implicationsHappiness is one of the main variables that influence people’s lives. As we have observed, this happiness has a direct and solid relationship with the individual’s level of satisfaction, with job satisfaction and satisfaction with social life being the most influential in this relationship between satisfaction and happiness. Therefore, these conclusions must be understood by both workers and employers and public administrations. Additionally, the relationship between happiness and prosocial behaviour is an interesting topic that the governments of countries and regions in Europe should consider.
