Abstract :
[fr] L’étude réalisée auprès de 45 personnes avec schizophrénie avait quatre objectifs : 1. caractériser les difficultés rencontrées dans les activités de la vie quotidienne à l’aide du questionnaire Profinteg ; 2. identifier les processus cognitifs prédictifs du niveau de difficulté total au questionnaire ; 3. identifier les processus cognitifs impliqués dans une activité multitâche, évaluée en situation réelle : la préparation d’une réunion ; 4. étudier la variabilité intra- et inter-individuelle des performances aux tests cognitifs et à la tâche fonctionnelle. Les résultats ont indiqué que la fonction d’inhibition jouait un rôle important dans le nombre élevé de difficultés d’initiation relevé au questionnaire Profinteg. Concernant la tâche préparation d’une réunion, les fonctions cognitives évaluées expliquaient 26 à 43 % de la variance dans plusieurs mesures : indice d’atteinte du but et de mémoire prospective, nombre d’erreurs et de violation de règles. La flexibilité et la vitesse de traitement étaient les meilleurs prédicteurs de la tâche. Enfin, différents profils de performances cognitives et fonctionnelles ont été mis en évidence. Ces résultats amènent à considérer la nécessité de mettre en correspondance, à un niveau individuel, les capacités cognitives et fonctionnelles, afin d’établir un programme de remédiation cognitive adapté à chaque personne. [en] This study, which included 45 persons suffering from schizophrenia, had four aims: 1. to characterize difficulties patients have with daily-life activities using the Profinteg questionnaire; 2. to identify the cognitive processes that are predictive of the total level of difficulty; 3. to identify the cognitive processes involved in a multi-tasking activity assessed in real situation: the meeting preparation task; 4. to characterize the intra- and inter-individual variability of performances in cognitive tests and functional task. The results indicated that inhibition plays an important role in a large number of meet initiation difficulties in the Profinteg questionnaire. Concerning the meeting preparation task, the assessed cognitive functions explained 26 to 43 % of the variance in several functional measures: the index of goal achievement, the index of prospective memory, the number of errors and the number of times a rule was not respected. Furthermore, flexibility and processing speed were found to be the best predictors of the task. Finally, various cognitive and functional profiles were observed. These results suggest the necessity, on an individual level, of putting together both cognitive and functional capacities in order to establish a personalized cognitive remediation program.
