*2.6.2.1 Study of the intrapsychic personal system of psychological adaptation*

In the 1980s and 1990s, the author investigated the dynamics of the MMPI basic scales before and after identical group hypnotherapy for two samples of patients with various types of Anxiety Disorders [21, 49, 68] (Mixed Anxiety-Depressive disorder, ASD, PTSD along with Dissociative and Somatoform disorders, OCD) (N = 145). Another group represented Anxiety Disorders due to Cerebrovascular disorder (N = 51). The design of the research included: (1) clinical estimation of psychotherapy efficiency; (2) analyses of MMPI data (basic validity and clinical scales) at the beginning and at the end of psychotherapy; (3) statistical analysis (descriptive statistics; means; nonparametric statistics [Wilcoxon matched pairs test] along with factor analysis—principal components method (varimax rotation)). For each clinical group of psychotherapy efficiency, we analyzed within the factor analysis the initial data, final data, and data on dynamics of psychotherapy (received by subtraction of final data from initial data).

Our study revealed two levels of the psychotherapy efficiency: significant improvement of the condition (equivalent of full recovery) with a full and persistent reduction of clinical disorders, and improvement of conditions with only partial or unstable reduction of clinical disorders [21, 49, 68]. This research has shown that patients, who displayed either significant improvement or improvement of conditions, differ from the very beginning and that there are two types of dynamics, which represent mechanisms of the therapeutic effect and final outcomes of psychotherapy.
