How is Happiness Measured?

Introduction. In order to develop an intervention program for women with unplanned pregnancies in vulnerable situations to help them improve their perception of happiness and well-being, it is necessary to select appropriate measurement tools to assess happiness and well-being. Methodology. For this purpose, studies that have used happiness and well-being measurement tools were reviewed in the Pubmed database. Results. Fifty-three studies measuring happiness and/or well-being of different populations are selected, revealing multiple constructs related to happiness and well-being that in turn elaborate different measurement tools. Conclusions. After reviewing the scientific literature, we conclude that a combination of questionnaires and interviews may be the best way to assess the happiness of pregnant women, providing both a quantitative and qualitative view of their experience.
