Interpersona was founded in 2007 by the Brazilian/Spanish researcher Agnaldo Garcia, in order to make knowledge about human relationships accessible to a wider international readership and to foster the publication of research in the field conducted all over the world.

The support of an international Editorial Board was fundamental for reaching readers in more than 90 countries and publishing articles from Europe, Asia, Africa, Oceania, North, Central, and South America.

The decision to transfer Interpersona to PsychOpen, taken in 2012, was motivated by sharing the same principles and values, i.e. to foster the free and open exchange of information, to improve the visibility of relationship research, and to optimize the international reception and citation of knowledge about personal relationships.
