Self-defining memories in recently detoxified alcohol-dependent patients.

Abstract

Patients with alcohol dependence have been shown to be impaired in recalling specific autobiographical events, yet little is known on how changes in the memory of these events may impact their self-representation. In this study, we examined Self-Defining Memories (SDMs), a specific type of autobiographical memory that plays a key role in the construction of personal identity, in 25 patients with alcohol dependence, abstinent from alcohol from 10 days to 6 months, compared to 28 control subjects. We observed that SDMs in patients were significantly less specific and included more reference to alcohol than those of controls. Patients also reported more SDMs with negative emotional valence and higher emotional intensity. These results suggest that recently abstinent alcohol-dependent patients may be prone to define themselves by negative events referring to alcohol consumption, which may contribute to an unfavorable perception of their self and subsequently of their ability to remain abstinent. These findings should be taken into account to optimize psychological approaches in the treatment of alcohol-dependence.
