The situation is in the consultative process, the client comes to therapy and leaves at his own discretion, that is, he does not work with the specialist on a permanent basis, gradually moving towards the result, but makes an appointment “according to the situation”. The process comes out broken, swaying, often incomplete – drifting. A different definition of the term is given by supporters of cognitive behavioral therapy (CBT). They interpret therapeutic drift as a decrease in the level of development of psychotherapists’ skills, the variable use of therapies based on the support of experience (in particular, behavioral interventions), and the erroneous implementation of such treatments, which potentially leads to further suffering of clients and public perception of psychological methods of treatment as ineffective. The aggravation of the problem of therapeutic drift is due to the biased thinking common to all psychotherapists. Also, psychotherapists have significant errors in the perception of their own level of qualification.
