Grossarth-Maticek's theory relating personality to health outcome via emotional dependence and suppression has received impressive support from several large-scale prospective studies. Nonetheless, several criticisms have been leveled at the theory and related research. The present experiment aimed to address the lack of theoretical clarity and empirical verification of Grossarth-Maticek's Type 5 personality. Type 5 individuals are proposed to exhibit "rational/antiemotional" or emotionally suppressive behaviour, and consequently rheumatoid arthritis, depression and cancer. Film segments were employed to arouse positive and negative emotions in healthy undergraduates (n=71), who were interviewed in order to assess their preparedness to discuss these emotions. Heart rate was measured during the film presentations and interviews in order to determine whether Type 5 in fact experience less emotion, or simply express emotions less. Subjects also completed questionnaires (GMPSI, BIDR, POMS (split half). Type 5-ness was not associated with low emotional expression, nor was this association stronger than with the other type scores. Type 5-ness was also not associated with less actual emotions, nor with a discrepancy between objective and self-report measures of emotion. Emotional expression with better overall response to the experimental procedures. Thus, Grossarth- Maticek's characterization of the Type 5 personality is not supported by the present study, and further investigation of this Type is warranted.
