Screening for Executive Dysfunction with the Frontal Assessment Battery: Psychometric Properties Analysis and Representative Normative Data for Brazilian Older Adults

This is the authors' abstract. We don't add key points for this paper.

Introduction:The Frontal Assessment Battery (FAB) is a for the assessment of executive functions.We investigated its validity and reliability and proposed normative data in a representative sample of older adults.Method: 391 healthy elderly subjects and 93 Alzheimer's disease (AD) patients performed the FAB.Internal consistency, convergent correlations, ROC curve and logistic regression were used to assess its psychometric properties.Results: We found good internal consistency, significant correlations with other tests and moderate accuracy (64%) for AD diagnosis.The use of specific subtests increased diagnostic potential (75%).Normative data stratified by age and education were proposed.Conclusion: The FAB showed adequate psychometric properties.The normative values stratified by age and education can improve its clinical use for neuropsychological assessment.
