Evidence of clinical, criterion, and convergent validity of the brazilian version of the Picture Free and Cued Selective Reminding Test with Immediate Recall (pFCSRT-IR)

Abstract

The picture Free and Cued Selective Reminding with Immediate Recall (pFCSRT-IR) has been widely useful for episodic memory assessment in patients with dementia due to Alzheimer’s disease (AD). This study presents adaptation and evidence of criterion and concurrent validity of the pFCSRT-IR for use in Brazil. The study was conducted in two complementary steps. Step A: authorization, translation,back-translation, and selection of a set of the 16 most nameable pictures in Brazil. Step B:n= 50 elderly individuals, 61–86 years of age (M = 73.26, SD= 6.70) and 3–25 years of education (M= 10.80,SD= 5.76), were evaluated with the pFCSRT-IR. Participants were categorized into two paired groups (25 AD/25 controls) for comparison in the pFCSRT-IR. In addition, a correlational analysis was conducted among pFCSRT-IR and Re Auditory-Verbal Learning Test (RAVLT) scores. Performance on the pFCSRT-IR was lower for the AD group. Moreover, considering all sample scores in the pFCSRT-IR and the RAVLT showed a significantly positive correlation with moderate to strong size (ρ > .40). The analysis showed evidence of convergent validity with external variables for the pFCSRT-IR. In conclusion, the Brazilian version of pFCSRT-IR has been shown to be a valid measure of episodic memory in the continuum of memory loss in aging.
