Over the last few decades, research has seamlessly confirmed the marked multicausal nature of compulsive buying, since variables from different realms (e.g., family, social, and contextual domains) have demonstrated their explanatory capacity. However, it has been personality variables that have, to a greater extent, aroused the interest of researchers, leading to what is now a cumbersome richness of personal constructs of different nature that seem to require some arrangement under integrative frameworks. The proposal by McAdams under the suggestive title of “What do we know when we know a person?” is, in this regard, especially attractive and thought-provoking. McAdams approaches us to the person as a whole by establishing three differentiated levels (dispositional traits, personal concerns or characteristics adaptations, life story), and it will be precisely these levels that will become the structure we will use to address the state of the art on compulsive buyers. The location of the multiple personal variables analyzed at each of the levels with a common grammar will allow us to identify what it is known, as well as what remains to be done in each space. Lastly, suggestions for the future are given, with particular emphasis on advancing our understanding of the person from each of the academic vantage points but also the suitability of designing studies that integrate and/or build bridges between dispositional traits, characteristic adaptations, and life narratives. The hope is that research in the coming years satisfactorily integrates the different visions of the person to achieve a more comprehensive, nuanced portrait of a person with compulsive buying problems.
