The self-regulation system, in this context, underlines disturbances in affect regulation, superego pathology and an inadequacy in the function of containing of caregivers in the development of addictions. The aim of this study is, thus, to scrutinize the self-regulation system disorders in patients diagnosed with alcohol use and/or substance abuse disorder via projective tests. In accordance with this purpose, 20 hospitalized patients were tested with the Rorschach and Thematic Apperception Tests; and the contents of the results obtained from the participants were interpreted according to the French School system. Results have been found to be supportive of the aforementioned disturbances in the self-regulation system.
