The report considers the potential for applying contemporary philosophical theories (which distinguish classical, nonclassical, and postnonclassical types of scientific rationality) to the specification of theoretical methodological principles in the study of clinical psychology. We prove that psychological syndrome analysis (developed by the Vygotsky-Luria-Zeigarnik school), taken as a system of principles for organizing research as well as for interpreting its results, conforms to the epistemological complexity of the object of study in clinical psychology, which is understood in the postnonclassical scientific view as a self-developing system. We present an example of the formation of a psychosomatic syndrome in 290 patients with mitral-valve prolapse, applying methods of qualitative and statistical data analysis in a longitudinal clinical-psychological study. We prove that the syndrome is system-defined and has a multilevel character, and that its structure is determined by several factors: the motivational factor (with the domination of the failure-avoidance motive and the unsatisfied self-approval need); the factor of the emotional-regulation disorders, represented by both excessive emotional repression and lack of emotional control; and a psychophysiological factor. We argue that a psychosomatic syndrome can be used as a means for approaching not only diagnostic but also prognostic tasks both in clinical psychology and in medicine. We conclude that the results of our empirical study, conducted within the framework of postnonclassical philosophy and using the methods of psychological syndrome analysis, not only expand the scientific background on the nature of a particular disease (mitral-valve prolapse) but also pose further questions whose investigation will broaden our view of the psychological mechanisms of psychosomatic-syndrome genesis.
