This chapter describes results of several research projects developed by the author studying the changes in the level of satisfaction with quality of life of people in Argentina. The research was conducted from 2002 to 2010. The chapter begins with the results of the first research project developed immediately after the national political, economic, and social crisis that besieged the whole country in 2001, and extends to the last survey that took place in 2010. In 2002, 2003, and 2005, the survey applied the Well-Being Index (Cummins et al. 2001). When politics and social conditions began to change in a positive way, another survey was conducted to capture quality of life in relation to human capabilities (Anand et al. 2007). The last project focused on the ESCVP (Tonon 2010), a measure capturing the level of satisfaction with quality of life in the country. The results of these studies show that the average level of life satisfaction is higher than the level of satisfaction with the living conditions in Argentina, in spite of the increases in life satisfaction since the change of government in 2003. Finally, it is important to note that the conjunctive use of qualitative and quantitative research related to quality of life can offer public policy officials better and more complete information to guide future policies.
