Abstract
BackgroundThis study examined the psychometric relationship between the Word and Picture versions of the Free and Cued Selective Reminding Test (FCSRT) and developed an equation for score conversion. MethodsOne hundred and eight-seven participants were administered the FCSRT-Picture and FCSRT-Word on two visits using a randomized counterbalanced design. ResultsParticipants had a mean age of 82.1 (standard deviation or SD = 5.4) and mean education of 14.5 (SD = 3.3) years. Mean FCSRT-Picture Free Recall score (mean 33.0 years, range: 17–44 years) was 7.9 points higher than the Word score (mean 25.1 years, range: 3–43 years). The Picture and Word FCSRT correlations for Free Recall and Total Recall were r = 0.56, P < .01 and r = 0.46, P < .01, respectively. DiscussionThe Picture and Word versions of the FCSRT were moderately associated in a sample of cognitively normal older adults. The score mean differences and variability between FCSRT-Picture and FCSRT-Word indicate that their scores should not be considered equivalent.

Memory is a complex cognitive construct that holds enormous significance for clinicians, researchers, and the general population, older adults
We found that the Picture and Word versions of the Free and Cued Selective Reminding Test (FCSRT) were moderately associated in a sample of cognitively normal older adults
We provide two formulas to facilitate the conversion of free recall scores between the two versions among nondemented older adults
Summary
Memory is a complex cognitive construct that holds enormous significance for clinicians, researchers, and the general population, older adults. Memory abilities decline over the adult lifespan [1,2,3], are a crucial feature of the diagnosis of dementia [4], and critically support the. Preliminary analyses in support of this work were presented at the Alzheimer’s Association International Conference Annual Meeting, July, 2012. M.E. Zimmerman et al / Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring 1 (2015) 94–100. We have shown [15] that the FCSRT has a stronger predictive utility for the identification of individuals who will develop dementia over a 2- to 4-year period compared with a widely used test of episodic memory, the Logical Memory subtest of the Wechsler Memory Scale–Revised [16]. The FCSRT is a strong correlate of neuroimaging and neuropathological markers [17,18,19,20,21]
