Cognitive deficits are clearly associated with poor everyday life functioning in persons diagnosed with schizophrenia. However, previous studies have primarily used questionnaires to assess everyday life functioning. We developed a computerized real-life activity task (shopping task), where participants are required to shop for a list of seven grocery store items. Thirty individuals diagnosed with schizophrenia and 30 healthy controls were administered an extensive battery of cognitive tests and the computerized shopping task. Performances on the computerized shopping task significantly differentiated patients and healthy controls for several variables. Moreover, performance on the shopping task was significantly correlated with verbal episodic memory, cognitive flexibility, planning, processing speed, and inhibition. Finally, performance on the computerized shopping task was significantly correlated with various clinical variables and with a global measure of social functioning. These findings suggest that the computerized task used in the present study provides an indication of the level of everyday life functioning and cognitive functioning of persons diagnosed with schizophrenia, and, therefore, may be viewed as a valuable instrument in both an evaluation and remediation context.
认知缺陷与被诊断为精神分裂症的个体日常生活功能不良明显相关。然而，以前的研究主要使用问卷来评估日常生活功能。我们开发了一种计算机化的真实活动任务（购物任务），参与者需要购买清单上的七件杂货店商品。30 名被诊断为精神分裂症的个体和 30 名健康对照组接受了广泛的认知测试和计算机化购物任务。在计算机化购物任务上的表现，在几个变量上显著区分了患者和健康对照组。此外，购物任务的表现与词语情景记忆、认知灵活性、计划、加工速度和抑制显著相关。最后，计算机化购物任务的表现与各种临床变量以及社会功能的整体衡量标准显著相关。这些发现表明，本研究中使用的计算机化任务提供了被诊断为精神分裂症个体的日常生活功能和认知功能的水平指示，因此，可能被视为评估和矫正背景下的一种有价值的工具。
