To determine the equivalence of two screens of cognitive functioning: the Short Portable Mental Status Questionnaire (SPMSQ) and the Orientation-Memory-Concentration (OMC) test.
The design was cross-sectional and longitudinal.
Four rural and one urban county in the Piedmont region of North Carolina (n = 3210).
A stratified random cluster sample (n = 3210) of people 68 years of age and older.
SPMSQ and OMC at the fourth wave of the Duke Established Populations for Epidemiologic Studies of the Elderly (EPESE); disability, depression, and death measurements from the fourth through seventh waves of EPESE; demographic characteristics.
On the SPMSQ and the OMC (r = .80), 15.3% and 38.4%, respectively, of those tested were rated cognitively impaired. Poorer scores were associated with older age, black race, and less education. These associations were attenuated on the dichotomized SPMSQ but not on the OMC. Both measures predicted disability and depressive symptomatology currently and 3 years hence and death.
The SPMSQ and OMC, although highly correlated, are not equivalent. Association with race and education are greater for the OMC, whereas an association with age exists for both measures. The milder level of impairment identified by the OMC increases predictive capacity.
确定两种认知功能筛查工具的等效性：简易便携式精神状态问卷（SPMSQ）和定向-记忆-注意力（OMC）测试。
采用横断面和纵向设计。
北卡罗来纳州皮埃蒙特地区的四个农村县和一个城市县（n = 3210）。
68岁及以上人群的分层随机整群样本（n = 3210）。
杜克老年流行病学研究既定人群（EPESE）第四轮调查中的SPMSQ和OMC；EPESE第四轮至第七轮调查中的残疾、抑郁和死亡测量指标；人口统计学特征。
在SPMSQ和OMC上（r = 0.80），接受测试者中分别有15.3%和38.4%被评定为认知受损。得分较低与年龄较大、黑人种族以及受教育程度较低有关。在二分法的SPMSQ上，这些关联减弱，但在OMC上没有减弱。两种测量方法都能预测当前和3年后的残疾及抑郁症状以及死亡情况。
SPMSQ和OMC虽然高度相关，但并不等效。OMC与种族和教育的关联更强，而两种测量方法都与年龄有关。OMC所确定的较轻程度的损伤增加了预测能力。
