In a community survey, subjects and their informants were asked the same questions about memory and intellectual decline in the subjects. Subjects and informants both commonly reported cognitive decline, although in most cases the decline was not seen as interfering with daily life. However, when responses from subjects and informants were cross-tabulated, agreement was found to be poor. For subjects, reports of cognitive decline were correlated with anxiety and depression symptoms and with trait neuroticism. Subjects' reports were uncorrelated with age and only weakly correlated with cognitive test performance, indicating little validity. By contrast, informants' reports were correlated with the subjects' cognitive test performance and age, but also with the informants' own anxiety and depression symptoms. Although informants' reports have validity, they may also be contaminated by the informants' affective state.
在一项社区调查中，研究人员向受试者及其提供信息者询问了关于受试者记忆和智力衰退的相同问题。受试者和提供信息者都普遍报告了认知衰退，不过在大多数情况下，这种衰退并未被视为干扰日常生活。然而，当将受试者和提供信息者的回答进行交叉列表分析时，发现二者的一致性较差。对于受试者而言，认知衰退的报告与焦虑和抑郁症状以及特质神经质相关。受试者的报告与年龄无关，且与认知测试表现仅有微弱关联，表明其有效性较低。相比之下，提供信息者的报告与受试者的认知测试表现和年龄相关，但也与提供信息者自身的焦虑和抑郁症状相关。尽管提供信息者的报告具有一定有效性，但它们可能也受到了提供信息者情感状态的影响。
