Special attention is paid to the analysis of the clinical-psychological effectiveness of cognitive-behavioral therapy (CBT) in depressive disorders, taking into account the relationship between depressive symptoms and self-regulation styles. The subject of the research is the dynamics of the severity of depressive symptoms and the parameters of behavioral self-regulation, as well as their interconnection in patients with depression during the CBT process. The aim of the study was to evaluate the impact of CBT on the level of depressive symptoms and self-regulation styles, as well as to analyze the relationships between clinical and regulatory indicators. The methods employed included a clinical-psychological examination using the MADRS depression scale and the self-regulation styles questionnaire by V.I. Morosanova, as well as the application of correlational analysis. The main limitations of the study are related to the limited sample size and the lack of long-term follow-up, which reduces the ability to assess the stability of the identified effects and their generalizability. The materials and methods included clinical-psychological examination using the MADRS depression scale and the self-regulation styles questionnaire by V.I. Morosanova before and after the therapeutic intervention. The scientific novelty of the study lies in the integration of the assessment of clinical dynamics and regulatory psychological mechanisms, as well as in identifying the specifics of the relationships between the severity of depressive symptoms and individual components of self-regulation during psychotherapy. The dynamics of MADRS correlated with changes in reliability ( = 0.57; p " 0.0001), planning ( = 0.51; p " 0.0001), flexibility ( = 0.44; p = 0.0001), and overall self-regulation level ( = 0.53; p " 0.0001). In the CBT group, the decrease in MADRS was associated with an increase in planning ( = 0.43; p = 0.021), while no correlations were found in the control group. The main conclusions of the study are that simultaneous with clinical improvement, changes in self-regulation styles are noted, indicating their involvement in the structure of the therapeutic effects of CBT. The identified associations between the dynamics of depression and self-regulation indicators allow considering regulatory processes as one of the psychological mechanisms mediating the effectiveness of psychotherapeutic intervention.
