El uso de diagramas de satisfacción vital y parrillas biográficas como herramientas híbridas para la obtención de datos secuenciales

This article describes the characteristics of two types of hybrid tools that are useful for obtaining both quantitative and qualitative data. It reviews how these tools have been used in previously published studies and identifies the advantages and disadvantages of their use. The two types of tools in question are life satisfaction diagrams and biographical grids. Both types of diagrams were originally designed as instruments for obtaining quantitative data within life course research, and later came to be used as either hybrid tools or only as qualitative tools. Both types of diagrams are evaluated mainly on the use made by the author in studies in which he has participated. The main advantages identified can be summarised in two points: (1) the ease of obtaining an accurate representation of complex facts and (2) the opportunity for this representation to stimulate personal reflection. One main limitation common to both diagrams has been identified: they can be difficult to understand unless interviewees receive a clear explanation. This type of diagrams can be seen as a bridge between the life course perspective and mixed methods research, a combination that has been seldom addressed in the methodological literature.
