Temporal Stability of the Zulliger Test in Brazilian Adults

Abstract

Abstract The reliability of a test obtained over time is an indispensable measure to ensure the use of the instrument. This study aims to explore the temporal stability of the Zulliger test in Brazilian adults. A total of 20 participants, aged 18 to 59 years, answered a sociodemographic questionnaire and the Zulliger in Comprehensive System (ZCS). Data collection took place from 2009 to 2019 (Test) and in 2021 (Retest). ANOVA did not show differences between the values of 90 (99%) ZCS variables analyzed between test and retest; 68% of the variables showed agreement between 0.40 and 1.00, and 18%. Reflex responses; human movement, animal movement; weighted sum of color responses; sum of animal+inanimate movements; mixed determinants; art and clouds contents; Responses to card I; felt stimulation; cooperative movement; sum of critical special codes; degree of control and stress tolerance denoted high and excellent stability levels intraclass correlation coeficiente (ICC≥0,70). The ZCS demonstrates temporal stability, reliability, and psychometric properties that support its safe use.
