The current state of alcoholism, based on the achievements of neurosciences, indicates that it is a multifactorial disorder, in the development of which, although biological predictors play an important role, predisposing psychological characteristics are no less important. That is why the need for an integrated approach to the rehabilitation of addicts is obvious. The use of art therapy in the work with addicts is quite common, but its effectiveness, optimal duration, features of its influence on the dynamics of indicators of strong-willed self-control, aggressiveness, and self-assessment of alcohol abusers are not studied enough. This paper presents the results of a study conducted on the basis of “Reshenie” rehabilitation center, 48 patients who are being treated for alcohol addiction took part in it. The people were divided into experimental and control groups. The standard rehabilitation program of the center for the experimental group was supplemented by a specially developed art-therapeutic complex, the control group received only a basic rehabilitation course. The research shows that the inclusion of art therapy in rehabilitation significantly increases the indicators of positive dynamics of strong-willed self-regulation of behavior in general, the dynamics of self-assessment indicators and negative dynamics of indicators and forms of aggressive behavior in the experimental group. It is shown that in order to obtain a remarkable effect from the rehabilitation program using art therapy methods in correcting the ability to control behavior, strong-willed control, inadequately inflated self-assessment, the duration of the art therapy program must be at least 8 weeks.
