Abstract

INTRODUCTION: Judgment is the ability to make sound decisions after careful consideration of available information, possible solutions, likely outcomes and contextual factors. From a neuropsychological perspective, the concept of judgment involves memory, language, attention, reasoning and specially the executive functions. Loss of judgment has been described in Mild Cognitive Impairment (MCI) and dementia. The Test of Practical Judgment (TOP-J) is an originally American measure created for evaluate practical judgment in older adults. It is a 15-item (TOP-J/15) or 9- item (TOP-J/9) open-ended questionnaire in which participants listen to brief scenarios about everyday problems and report aloud their proposed solutions. This study aimed the adaptation of the TOP-J for use in Brazil, the development of a reduced version of this instrument and the verification of accuracy of both the versions in Brazilian sample composed of cognitively healthy controls and patients with mild cognitive impairment (MCI), Alzheimer\'s disease (AD) and frontotemporal dementia behavioral variant (FTD). METHODS: The sample consisted of 85 subjects with a minimum age of 50 years and minimum education of 4 years, being 24 controls, 26 MCI, 20 AD e 15 FTD. The participants were submitted to a neuropsychological assessment and TOP-J. RESULTS: In the TOP-J/15 Brazilian version (TOP-J/15-Br) and in the TOP-J/9 Brazilian version (TOP-J/9-Br) (reduced version), performance of controls was statistically better than the performance of MCI, AD and FTD patients, and performance of MCI was statistically better than AD and FTD patients. In TOP-J/15-Br, the reliability verified by Cronbach\'s alpha was 0.69 and the best cutoff for distinction between controls and patients was 30 (sensibility of 91,7%; specificity of 59% and area under the curve of 0,8). In the TOP-J/9-Br, Cronbach\'s alpha was 0.68 and the best cutoff point for distinguishing between judgment of controls and judgment of patients is 19, with a sensitivity of 79,2, specificity of 72,1 and area under the curve of 0.82. CONCLUSIONS: The TOP-J/15-Br and the TOP-J/9-Br showed robust psychometric characteristics for the intended use with a sample of the Brazilian population. Both were able to identify deficits of impaired of judgment already in patients with MCI and were able to distinguish judgment of controls from judgment of patients with good sensitivity and specificity (AU)
