Abstract. The worldwide increasing popularity of health psychology is illustrated by an analysis of data gathered at the International Congress of Psychology (ICP) in Berlin, 2008. The first analysis deals with the topics of interest that participants had stated when registering online for the congress. Out of 26 topics, health psychology obtained rank 9. The second analysis deals with the primary category in which abstracts were classified. Out of 6,252 abstracts, 10.65% were assigned to health psychology as the primary domain of research. These congress-based data may complement previous bibliometric data that attest to the increasing importance of health psychology.
