In the 1990s, Kempen and Hubert Hermans developed a new approach in cultural psychology around the concept of the dialogical self. In 1993, they published the seminal work "The dialogical self: Meaning as movement", and published several articles in "American Psychologist", "Journal of Personality" and "Theory & Psychology". Despite their success Kempen suffered from depression. In 2000, he died in Nijmegen four days before his retirement from the Radboud University.
