Analysis of Internal Structure of the Myokinetic Psychodiagnosis - PMK

Abstract The aim was to investigate the internal structure of Myokinetic Psychodiagnosis using exploratory factor analysis. The sample consisted of 300 subjects, 18-61 years of both genders from the state of Minas Gerais. The six test sheets were used and the application took place in a single session. The correction was performed with the a ruler, by evaluators experienced in the use and teaching of the instrument. The results showed the presence of seven factors, only three of which were similar to the original test structure. The alpha coefficients ranged from 0.57 to 0.92. The tracings of Emotionality dimension were not grouped into a single factor. Items related to 'zigs' and 'parallel' separated the factors Tensional Dimension and Tensional Prevalence. The test original structure was not confirmed. We discussed the structural weakness and the theoretical bases of the PMK.
