Validity of Zulliger-SC in the Cognitive Assessment of Elderly and Long-Lived Adults

Abstract

This study sought evidence of validity of the Zulliger method to evaluate cognitive processes in elderly and long-lived adults and to verify the relationship between cognition and external variables. Participated 142 subjects, aged between 18 and 96 years old. The Zulliger Comprehensive System (ZSC), Mini-Mental State Examination and sociodemographic protocols were used as of data collection. The older and long-lived adults presented a significant decrease in mediation (X-%, XA%, P) and abstract reasoning (M) when compared to young and middle-aged adults. Education and socioeconomic status (SES) demonstrated significant and positive correlations with cognitive processes (R, ZF, W, M, DQ+ and Intellectualization). The findings are fundamental to psychological practice and to directing measures for cognitive preservation in human aging.

The Reliability of the Zulliger Test (2009-2019): Case Studies

“…Recent literature reviews on ZSC (Cardoso et al, 2018;Grazziotin & Scortegagna, 2016) involving nonpatients (Grazziotin & Scortegagna, 2018;2021;Miguel et al, 2017) and based on contributions of Rorschach Performance Assessment System R-PAS (Gonçalves et al, 2019;Villemor-Amaral et al, 2016;Villemor-Amaral & Gomes, 2020) highlight the contributions and the need for advances in research on the psychometric properties of ZSC. It is noteworthy that studies on temporal stability are still rare, showing only the study by thus far.…”
