Consequences of cannabis use in schizophrenia patients

Method

- 2 groups;

- A meeting of 1 hour per week for 10 weeks for two groups;

AM REMEDIATION THERAPY (N = 5)

The program proposed differents tasks to patients: - a journal where they noted an event that took place the day before;

- The execution of an individual project; - Exercices to become better knew.

IPT (N = 3)

The patients have made the first module of the IPT: Cognitive differentiation.

After and before the therapies, patients were asked to completed TeMA for past and future (Neumann and Philippot, unpublished).

Introduction

- Schizophrenia is accompanied by deficit in autobiographical memories (AM). These patients instructed to recall a specific event distinctly located in time and place actually recall an extended event or a category of repeated events ;

- These impairments are correlated to difficulties in imagining specific events that might happen to them in the future(D’Argembeau, Raffard et Van-der-Linden, 2008);

- The previous study suggested that the specific autobiographical memory (past and future) may be improved by an AM remediation therapy(Blairy & al., accepted).

Results

The results showed :

• that the participants tend to recall more specific events after

therapies (M = 2,69), confound ITP and AM Therapy, compared to before therapies (M = 4), confounded pass and future events, t(6) = 3.28, p = .013.;

• No significative differences between the past and future

retrieval of specific memories before and after remediation in autobiographical memory, but there is a tendancy (see table 1);

• No difference between IPT group and AM remediation therapy

(see table 1).

Objective

The purpose of the present study was improved these deficits (specificity past and future events) in schizophrenia with a cognitive remediation. This intervention was compared with IPT de Brenner(Pomini & al., 1998).

Discussion

- Therapy seems to improve the retrieval of specific future and past autobiographical memories but the AM remediation therapy alone do not improve retrieval and projection;

- These results are probably due to small sample;

- In addition, the AM remediation therapy has been refined and we currently study the validity of the revised version of this cognitive intervention.
