Psicodiagnóstico Miocinético (PMK) is considered a useful technique for the evaluation of six personality factors in Brazil. Based on the theory proposed by Mira y Lopez, extreme manifestations of these dimensions are related to signs of psychopathology. This study aimed to investigate the predictive ability of measures of the PMK in the diagnosis of mood disorder. To this end, we compared measures of PMK in 31 individuals diagnosed with mental disorder and 31 controls matched on sociodemographic variables. We used Wilcoxon test and the results showed no differences between groups. It is concluded that measures of personality as calculated in this study were not sensitive to the presence of mental disorders of mood. In the Brazilian literature, current studies that had the purpose of understanding the PMK's capacity in differentiating group-criteria in psychopathological symptoms have not been found. New psychometric studies should be conducted to justify the interpretation suggested by Mira y Lopez.
