   Proposal Description:
   Consistency in the administration of neuropsychological tests is critical to obtaining valid and reliable results. The Wechsler Memory Scale (WMS) is one of the most frequently utilized tests amongst neuropsychologists in the United States (Rabin, Barr,  Burton, 2005). Clinician???s utilize WMS performance results to characterize nature of memory deficits, provide specific information about individual strengths and weaknesses, determine probable diagnoses, and develop treatment recommendations. Despite this, researchers have documented excessively high rates of error in the administration, scoring, and interpretation of neuropsychological assessments (Dumont  Willis, 2004). The current study seeks to examine the extent to which individuals in an older adult (>65 years) population received standard administration of the WMS Logical Memory Delayed subtest (LM II), including the extent to which non-adherence to standardized administration influences LM I performance outcomes. The WMS Logical Memory Immediate (LM I) and LM II subtests were administered to 46,146 participants in the Uniform Data Set (UDS Weintraub et al., 2009). Duration of time elapsed between LM I and LM II administration was noted for all subjects. The sample included 28,141 cognitively normal, 17,380 with probable Alzheimer???s dementia, and 625 with probable vascular dementia. Each study group was first split by time elapsed between LM I and LM II administration, including 4 subgroups total (???14, 15-24, 25-35, and ???36 minutes).  The majority of study participants in each group were administered the LM II after <25 minutes. Across cognitively normal and demented (AD, VaD) study groups, participants with a LM II administration delay of either ???14 or 15-24 minutes achieved a significantly higher raw score than those in the 25-35 minute delay group.  These findings highlight the importance of adhering to time-based administration guidelines when using standardized neuropsychological tests of memor
