[en] Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia, and in particular during multitasking activities. Multitasking refers to activities where the person has to: carry out and alternate between different tasks that vary in terms of priority, difficulty and duration; define the tasks’ targets; and where the person is faced with unexpected problems during the realization of these tasks (Burgess, 2000). However, the neurocognitive underpinnings of multitasking have never been explored in schizophrenia. Further, only two cognitive models exist in the literature, based on a student sample (Logie et al., 2011) and a neurological sample (Burgess et al., 2000). Both of these models suggest three primary constructs including Memory, Planning and Intent. However, there are several limitations related to the way multitasking was evaluated in these studies. We thus developed a computerized real-life activity task designed to take into account the multitasking nature of certain everyday life activities where participants are required to prepare a room for a meeting – the Computerized Meeting Preparation Task (CMPT). Using this new task, and based on previous studies (Burgess et al., 2000; Logie et al., 2011), the aim of the present study was to evaluate a new cognitive model of multitasking ability and that takes into account certain cognitive processes that are not integrated in existing models. Fifty-seven individuals diagnosed with schizophrenia and 41 matched healthy controls completed the CMPT. Participants were also evaluated with a battery of cognitive tests. The results suggest that the CMPT has a good sensitivity. Moreover, structural equation modelling confirmed the three underlying constructs of multitasking (Memory, Planning and Intent) which are underpinned by several cognitive functions and multitasking aspects. Taken together, this new cognitive model and the CMPT could be a good basis for cognitive intervention on multitasking.
