Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia and in particular during multitasking activities. 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. Twenty-one individuals diagnosed with schizophrenia and 20 matched healthy controls completed the computerized task. Patients were also evaluated with a cognitive battery, measures of symptomatology and real world functioning. To examine the ecological validity, 14 other patients were recruited and were given the computerized version and a real version of the meeting preparation task. Results showed that performance on the computerized task was significantly correlated with executive functioning, pointing to the major implication of these cognitive processes in multitasking situations. Performance on the computerized task also significantly predicted up to 50% of real world functioning. Moreover, the computerized task demonstrated good ecological validity. These findings suggest the importance of evaluating multitasking capacities in patients diagnosed with schizophrenia in order to predict real world functioning. [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 ▲]

Persons diagnosed with bipolar disorder often suffer from cognitive impairments. However, little is known concerning how these cognitive deficits impact their real world functioning. We developed a computerized real-life activity task, where participants are required to shop for a list of grocery store items. Twenty one individuals diagnosed with bipolar disorder and 21 matched healthy controls were administered the computerized shopping task. Moreover, the patient group was assessed with a battery of cognitive tests and clinical scales. Performance on the shopping task significantly differentiated patients and healthy controls for two variables: Total time to complete the shopping task and Mean time spent to consult the shopping list. Moreover, in the patient group, performance on these variables from the shopping task correlated significantly with cognitive functioning (i.e. processing speed, verbal episodic memory, planning, cognitive flexibility, and inhibition) and with clinical variables including duration of illness and real world functioning. Finally, variables from the shopping task were found to significantly explain 41% of real world functioning of patients diagnosed with bipolar disorder. These findings suggest that the shopping task provides a good indication of real world functioning and cognitive functioning of persons diagnosed with bipolar disorder. [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 ▲]
