对197项认知老化研究的调查显示，很少使用结构化健康评估和随机招募。在这项研究中，一个健康筛查问卷，以确定受试者的医疗问题，可能会损害认知管理到315名60岁及以上的成年人谁是通过随机数字拨号招募。根据自我报告的医疗问题，35%的受试者被排除在外。被排除者年龄较大（p<. 001)并且倾向于男性，但在教育程度上与那些通过筛选的人没有区别。通过筛选并决定参加神经心理学研究项目的受试者更年轻（p<. 001），受教育程度较好（p<. 001），并且更可能是男性（p<. 001)而非参与者。这些发现表明，需要仔细评估，选择和描述的主题，以帮助解释认知老化研究。需要进一步关注健康状况，以帮助解释认知老化研究。虽然随机招募老年人是可行的，但获得代表性样本可能需要对人口统计变量进行分层。
A survey of 197 cognitive aging studies revealed infrequent use of structured health assessments and random recruitment. In this study, a health screening questionnaire developed to identify subjects with medical problems that might impair cognition was administered to 315 adults aged 60 and older who were recruited by random digit dialing. On the basis of self-reported medical problems, 35% of the subjects were excluded. Those excluded were older (p<. 001) and tended to be male but did not differ in education from those who passed the screening. Subjects who passed the screening and decided to participate in a neuropsychological research project were younger (p<. 001), better educated (p<. 001), and more likely to be male (p<. 001) than nonparticipants. These findings suggest that careful assessment, selection, and description of subjects is needed to aid interpretation of cognitive aging research. Further attention to health status is needed to aid interpretation of cognitive aging research. Although random recruitment of the elderly is feasible, obtaining representative samples may require stratification on demographic variables.
