Persons diagnosed with bipolar disorder and alcohol dependency are frequently subject to cognitive impairments and encounter difficulties during everyday life activities. However, little is known how these deficits interact in real life. Moreover, previous studies have primarily used questionnaires or observational methods to assess everyday life functioning, both of which contain a number of limits. In order to address some of these limits, we developed a computerized real-life activity task, in particular, a shopping task where participants are required to shop for a list of 8 grocery store items in a virtual supermarket. Twenty individuals diagnosed with alcoholic dependence and 21 patients diagnosed with bipolar disorder were compared with healthy controls (20 and 21, respectively), matched for age, sex and educational level. All participants completed the shopping task, and both clinical groups were evaluated with an extensive battery of cognitive tests (assessing executive functioning, attention, processing speed and memory), clinical scales and a measure of real world functioning. Results showed that, for both clinical groups, performance on the computerized shopping task significantly differentiated patients and healthy controls for a number of variables, especially total time to complete the shopping task. Performances on shopping task variables, in both clinical groups, were also significantly correlated with cognitive tests measuring processing speed, episodic memory, cognitive flexibility and inhibition. Finally, performances on the computerized shopping task were significantly correlated with real world functioning in both patient groups. These findings suggest that the computerized task used in the present study provides a valid indication of the level of real world functioning for these clinical populations, and therefore may be viewed as a valuable instrument in both an evaluation and remediation context.

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 ▲]

Persons diagnosed with bipolar disorder and alcohol dependency are frequently subject to poor everyday life functioning. However, previous studies have primarily used questionnaires or observational methods to assess everyday life functioning, both of which contain a number of limits. In order to address some of these limits, we developed a computerised real-life activity task, in particular, a shopping task where participants are required to shop for a list of 8 grocery store items. Twenty individuals diagnosed with alcoholic dependence and 21 patients diagnosed with bipolar disorder were compared with 20 and 21 matched healthy controls, respectively. All participants completed the shopping task, and both clinical groups were evaluated with an extensive battery of neuropsychological tests and a measure of global functioning. Results showed that, for both clinical groups, performance on the computerised shopping task significantly differentiated patients and healthy controls for a number of variables, especially total time and mean time to consult the shopping list. Performances on shopping task variables, in both clinical groups, were also significantly correlated with neuropsychological tests measuring verbal episodic memory, processing speed and selective attention. Finally, performances on the computerised shopping task were significantly correlated with various clinical variables and with global functioning in both patient groups. These findings suggest that the computerised task used in the present study provides a valid indication of the level of everyday life functioning for these clinical populations, and therefore may be viewed as a valuable instrument in both an evaluation and remediation context.
