Aim of the study:
The main aim of research is to analyse the dynamics of self-regulation functions in connection with the treatment of people addicted to alcohol. Another goal is to compare 2 groups after one year: those who maintained abstinence and who returned to addiction.

Subject or material and methods:
The studies were designed as longitudinal with quasi-experimental procedure. The first measurement was performed in two-week time of treatment, the second at the end of the basic stage of the treatment and the third – after a year. The research was conducted in 12 centres in the group of 977 patients (M 76%, F 24%).

Results:
In ABS group, in Self-motivation, the change was statistically significant between the first and the second measurement. In Activation control in ABS group there was significant difference between the first and the second measurement, and the first and the third measurement. In nABS group the change was significant between the second and the third measurement. After a year the difference between ABS and nABS groups was statistically significant.

Discussion:
The research on self-regulation functions was conducted with SSI-K Inventory. Semi-structured interview was performed twice: at the beginning of the treatment and after one year to analyse the indicator of recovery. In the evaluation of the dynamics of self-regulation, ANOVA was used.

Conclusions:
Treatment and abstinence influence changes in self-regulation. The effects of these changes are observed in people who were maintaining abstinence in one-year period, which indicates their stronger ability to act according to their needs, facilitating the development of ‘Self’.
