Abstract
Very brief screening tests are useful in primary care, but may show reduced sensitivity in detecting Alzheimer’s disease or other dementias in the early stages and may show an education or age bias. We examined the reliability, validity, sensitivity, specificity and relationship with demographic variables of a novel, very brief memory screening test that makes limited language demands. Participants were 452 neurological patients with different diagnoses and a community-dwelling sample of 119 middle-aged and older controls. The 5 Objects Test requires the recall of the locations of five everyday objects, immediately after placement and after a brief period of time. The test was unaffected by age and education and showed good reliability and discriminant validity. In receiver operating characteristic (ROC) analyses, specificity was high across a range of sensitivities in all four main comparisons (AD cases versus controls; all dementia cases versus controls; memory-impaired versus non memory-impaired patients; MCI cases versus controls), and sensitivity was lowest in differentiating MCI cases from controls. The test showed similar areas under the ROC curve to the much longer modified Mini Mental State Examination. The 5 Objects Test is a reliable and valid very brief screening test that is suitable for primary care. Because of its limited linguistic demands, the test is appropriate for persons with limited language use or from different linguistic backgrounds.
