Alexithymia, emotional disclosure, and health: a program of research

This article reviews a program of research on alexithymia, emotional disclosure, and health. The article first describes two lines of research and then outlines current work attempting to integrate these lines. The first research line involves basic correlational studies on alexithymia's link to health problems; these studies suggest that alexithymia is a potential risk factor for symptoms and illness behavior, although not necessarily organic disease. The second research line involves experimental studies of the health effects of emotional disclosure via expressive writing or talking; these studies suggest that disclosure improves health on average, but that the effects are not that robust and that various moderators likely are involved. The next section of the article describes recent attempts to integrate the two research lines by examining how baseline levels of alexithymia influence the effects of emotional disclosure; these analyses suggest that alexithymia interferes with or attenuates the health benefits of disclosure. Finally, the article describes initial forays into research on interventions with the alexithymic patients. This evolving program of research demonstrates the value of integrating emotion, personality, and health, and highlights the bidirectional relationship between clinical problems and basic research.
