Improvements in autobiographical memory in schizophrenia patients after a cognitive intervention: a preliminary study.
BACKGROUND
Schizophrenia is associated with a reduction in accessing specific autobiographical information. This is consistent with the abnormal development of personal identity that characterizes this mental disorder. Using a schizophrenic population, the present study evaluates the effect of a cognitive intervention on autobiographical memory and the capacity to project oneself in the future.


METHODS
The intervention consisted of group sessions, during which participants were trained to recollect specific events reported in their diary. Furthermore, exercises to stimulate their thoughts about their personal identity were proposed. An autobiographical memory test was administrated before the intervention, after the intervention and at the 3-month follow-up. In addition, neuropsychological and affective assessments were conducted before and after treatments. Patients' performances were compared to those from the control group.


RESULTS
The ability to recall specific events was improved by the cognitive intervention, and the benefits were preserved 3 months later. However, no neuropsychological or affective benefit was found.


CONCLUSIONS
Despite positive results on specific memory, any significant benefits have yet to be extended to other clinical variables such as symptom reduction and neuropsychological/social functioning. Nevertheless, the results revealed that cognitive remediation therapy could be a useful additional intervention for autobiographical memory deficits in schizophrenia patients.
