The aim of the study is to develop and test an express diagnostic method for determining psychosemantic markers of self-regulation components deficiency in clients during an online counseling situation. The article describes the specifics of the population's appeals to psychological services from universities for psychological help since the beginning of the COVID-19 pandemic. It shows that people's requests have a different focus: problems with behavior, problems with cognitive functions, problems with emotions, will, motivation, etc. However, a common component in all requests is a pronounced lack of self-regulatory resources in solving problems that arise in situations of increasing uncertainty. The study results of psychosemantic markers of components deficiency in human selfregulation during situations of increasing uncertainty are presented. The relevance of the results of the components deficiency in human self-regulation is determined by the fact that self-regulation is an important resource of an individual, which contributes to successful adaptation to various life difficulties and situations, including situations of forced increasing uncertainty such as the COVID-19 pandemic. Using the analysis of various theoretical works and empirical studies, 4 main groups of deficits (deficiencies) of self-regulation, characteristic of people in a situation of increasing uncertainty, were identified: deficiency of the operational component of self-regulation, deficiency of the emotional-volitional component of selfregulation, deficiency of the motivational component of self-regulation and deficiency in the individual-personal component of self-regulation. This empirical study of psychosemantic markers of deficiency in self-regulation components was carried out using the method of content analysis of requests from people who applied for help to the TSU psychological service during the COVID-19 pandemic. It was noted that the number of deficiencies in different people are both minimal (only 1 type of deficiency occurs) and maximum (all 4 identified types of deficiency occur). Thus, the predominant type of deficiency among people who applied for help to the psychological service of TSU was the deficit of the emotional-volitional component of self-regulation, namely, problems with the regulation of fear, anxiety and aggression. This fact indicates that the situation of uncertainty to a greater extent affected the emotional component of the psyche. In addition, it is the selfregulation of emotions that is one of the most complex types of self-regulation, and this is probably why there are more related requests to it. The deficit of the operational component of self-regulation was the least common. The novelty of the study is the indications psycho-semantic tools, which allows collecting diagnostic information in the course of working with a client on an online consultative platform.
