This study examined the relationships between a set of real-world performance measures and a set of executive function measures with a sample of community based individuals with schizophrenia (N=80). Participants were given a battery of cognitive tests and were evaluated with a real-world performance measure, the Test of Grocery Shopping Skills (TOGSS). Using canonical correlation analysis, executive functions of planning, problem solving, working memory, and task persistence were significantly related to grocery shopping efficiency and accuracy. Two canonical variates with moderate correlations (0.547 and 0.519) explain that 30% of the variance in the executive function and grocery shopping measures was shared. These results identify patterns of association between executive function performance and the independent living skill of grocery shopping indicating the Test of Grocery Shopping Skills may be considered a sensitive measure of executive function performance in a real-world setting.
本研究以 80 名社区精神分裂症患者为样本，考察了一系列真实表现测量指标与一系列执行功能测量指标之间的关系。研究人员给参与者进行了一系列认知测试，并使用真实表现测试（Test of Grocery Shopping Skills，简称 TOGSS）对其进行评估。通过典型相关分析，规划、解决问题、工作记忆和任务坚持等执行功能与购物效率和准确性显著相关。两个具有中等相关性（0.547 和 0.519）的典型变量解释了 30%的执行功能和购物测量指标之间的方差是共有的。这些结果确定了执行功能表现与独立生活技能（例如购物）之间的关联模式，表明 Test of Grocery Shopping Skills 可能被视为真实环境中执行功能表现的敏感测量指标。
