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. [less ▲]

Background: Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia. Moreover, patients seem to demonstrate particular difficulties during complex and multitasking activities, such as cooking a meal (Semkovska et al., 2004). 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, at present, patients’ multitasking capacities have not been adequately examined in the literature due to an absence of suitable assessment strategies. We thus recently developed a computerized real-life activity task designed to take into account the complex and multitasking nature of certain everyday life activities where participants are required to prepare a room for a meeting – the Computerized Meeting Preparation Task (CMPT) Methods: Twenty-one individuals diagnosed with schizophrenia and 20 matched healthy controls completed the CMPT. During the CMPT, participants found themselves in a virtual room that they had to prepare for a meeting while respecting a list of instructions (the placement of the guests, the needed objects, the desired drinks, etc.). Patients were also evaluated with an extensive cognitive battery (assessing executive functions, attention, processing speed and memory), measures of symptomatology and real world functioning. To examine the ecological validity of the CMPT, 14 others patients were recruited and were given the computerized version and a real version of the meeting preparation task. Results: Results demonstrated that performance on the CMPT significantly differentiated patients and healthy controls for the total time to complete task, planning efficiency, and the respect of the instructions. Moreover, these variables were significantly correlated with executive functioning (i.e. cognitive flexibility and planning), suggesting the major implication of these cognitive processes in multitasking activities. Performance on the CMPT also significantly predicted up to 50% of real world functioning. Finally, performances on the computerized version and the real version of the meeting preparation task were highly correlated, suggesting good ecological validity. Discussion: In this study, we created a novel task involving the multitasking nature of real world activities. The results demonstrated that this approach provides a good indication of the real world functioning in patients diagnosed with schizophrenia. Moreover, results suggest a particular implication of executive functioning in multitasking activities. These findings suggest the importance of evaluating multitasking capacities in patients diagnosed with schizophrenia in order to predict real world functioning. [less ▲]

Objective: The objective was to create a new measure of everyday life functioning by developing a computerized real-life activity task where participants are asked to prepare a room for a meeting. Background: Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia. However, everyday life functioning is usually evaluated with questionnaires, performance-based or observation assessments, all of which contain a number of limits. Method: Twenty-one individuals diagnosed with schizophrenia and 21 matched healthy controls completed the computerized meeting preparation task. Patients were also evaluated with an extensive cognitive battery and several measures of symptomatology and everyday life functioning. Results: Results showed that performance on the computerized task significantly differentiated patients and controls for a certain number of variables. These variables, summarized in a global score, were significantly correlated with both cognitive and everyday life functioning. Moreover, this composite score significantly predicted 39% of everyday life functioning, whereas a cognitive composite score only predicted 22%. In addition, when the meeting task composite score was combined with symptomatology and the cognitive composite score, these measures significantly predicted up to 73% of everyday life functioning. Conclusion: The findings suggest that the meeting preparation task provides a good indication of the level of everyday life functioning in patients with schizophrenia, and may be viewed as a valuable instrument in both an evaluation and remediation context.

Objective. The effectiveness of an individualized and everyday approach to cognitive rehabilitation for schizophrenia was examined in a case study. Method. After cognitive and functional assessment, concrete objectives were targeted for the person’s everyday complaints. Strategies were constructed based on an analysis of the cognitive profile, daily life functioning, and processes involved in activities. They included a memory strategy for reading, a diary to compensate memory difficulties, and working memory exercises to improve immediate processing of information when reading and following conversations. Efficacy was assessed with outcome measures. Results. The program had beneficial effects on the person’s cognitive and everyday functioning, which persisted at a 3-year follow-up. Conclusion. Findings provide suggestive evidence that an individualized and everyday approach may be a useful alternative in order to obtain ameaningfully lasting transfer of training to daily life, compared to the nomothetic ones which dominate the field.

The aim was to assess the efficacy of a modified version of Goal Management Training (GMT) in a person with schizophrenia who had difficulties in attaining the final goal for new and multitasking daily-life situations. GMT is designed to improve abilities in establishing goal-directed plans and carrying them out effectively. Beneficial effects of GMT were measured for several clinical questionnaires, laboratory tasks, and three real-life situations: meal preparation (trained, familiar); washing (nontrained, familiar); meeting preparation (nontrained, unfamiliar). The results revealed improvement in planning and on trained laboratory and meal preparation tasks and a generalization of GMT effects on nontrained laboratory and everyday tasks. Self-esteem also improved. Finally, a two-year followup indicated the durability of the beneficial effects. [less ▲]

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. [less ▲]

It is now well recognized that cognitive dysfonctions contribute to a decisive way to the difficulties of the everyday, social and professional life of the people with schizophrenia. The cognitive variables would explain between 16 and 30 % of the variance in the functional status when assessed one to three and a half years later. However, the specificity of the complex relationships between the cognitive domains and the functional variables still remain to identify. To this end, it is necessary to carry out studies by respecting various principles: 1. Selecting not multi-determined cognitive tasks; 2. Investigating specific daily-life tasks (e.g. shopping, choosing a menu, preparing a meal), in particular by an observation in real situation in order to identify the problematic components; this has to be made by determining a priori hypotheses regarding the cognitive nature of the difficulties; 3. Taking into account the heterogeneity of the cognitive deficits and the functional difficulties of people with schizophrenia. It also remains to investigate the presence of mediator variables of the relationships, such as the potential of learning, the social cognition, the metacognitive processes and the intrinsic motivation. Besides, other personal or environmental factors can also play a role in the functional status as for example, the negative symptoms, the awareness that has the person of his(her) state and its consequences, or the critical attitude of relatives towards the person with schizophrenia.

The aim of this study was to investigate the effectiveness of the attention training technique (ATT) on the frequency of intrusive thoughts experienced by a person with schizophrenia in her daily life. The attentional procedure was designed to attenuate self-focused attention and to reinforce attentional control and consisted of auditory external exercises. Homework practice was included to promote transfer to everyday life. The efficacy and specificity of the ATT were assessed with cognitive, functional, and control measures. The impact of ATT on symptomatology, work functioning, and self-esteem was also measured. Postrehabilitation results showed that, after nine training sessions, there was a reduction in intrusive thoughts for the cognitive and ecological outcome measures. Selective attention, attention switching, and resistance to distractive interference specifically improved. The person reported a reduction in intrusive thoughts in her daily life. In addition, positive symptoms decreased. Finally, a 6-month follow-up assessment revealed the maintenance of most of the beneficial effects in daily life. [less ▲]

Working memory problems have been identified as a core cognitive deficit in schizophrenia. In this paper, we present the results of a cognitive rehabilitation programme (Duval & Coyette, 2005) administered to a schizophrenia patient, and specifically designed to improve the updating sub-component of working memory. The original feature of this programme was that it involved two types of updating exercises: cognitive and ecological. The purpose was to enable the patient to acquire cognitive strategies that alleviate the mental load of the central executive and to transfer them to daily life. The specificity and efficacy of the programme were assessed with multiple (cognitive, ecological and non-target) baseline measurements. In addition, several questionnaires were administered to assess the effect of the programme on subjective cognitive complaints affecting daily life, psychiatric symptoms and self-esteem. The results demonstrated the efficacy of the rehabilitation programme on the updating function and the generalisation of these beneficial effects to daily life. A significant decrease in both subjective cognitive complaints and psychiatric symptoms was also observed. However, the patient's self-esteem did not improve. [less ▲]

OBJECTIVE: Over the last decade, the Cambridge Neuropsychological Test Automated Battery (CANTAB), which comprises visuo-spatial tasks, has been utilized in cognitive studies of schizophrenia. A clear approach concerning the usage of CANTAB for the appraisal of neurocognitive dysfunction in schizophrenia is currently lacking. METHOD: In this paper, we have first reviewed the overall applications of CANTAB and then evaluated methodological strengths and weaknesses of CANTAB as a neurocognitive battery for schizophrenia. We carried out a systematic search and assessment of studies where CANTAB was utilized to measure cognitive function in schizophrenia. We have also attempted to quantify the available data and perform a meta-analysis, but this approach turned out to be still premature. RESULTS: CANTAB has enabled researchers to highlight significant deficits affecting broad cognitive domains in schizophrenia, such as working memory, decision-making, attention, executive functions and visual memory. So far, the most consistent deficit observed with CANTAB testing has been attentional set-shifting, suggestive of fronto-striatal dysfunctions. In addition, preliminary evidence points towards the potential use of CANTAB to identify cognitive predictors of psychosocial functioning, to describe the relationships between symptoms and cognition, and to measure the impact of pharmacological agents on cognitive functioning. CONCLUSION: CANTAB has been used successfully to highlight the range of visuo-spatial cognitive deficits in schizophrenia, producing similar results to those obtained with some traditional neuropsychological tests. Further studies validating the use of CANTAB following the standard set by Measurement And Treatment Research to Improve Cognition in Schizophrenia (MATRICS) are warranted. [less ▲]
