Construct validity of the Functional Assessment of Verbal Reasoning and Executive Strategies (FAVRES)

Abstract

ABSTRACTBackground: The Functional Assessment of Verbal Reasoning and Executive Strategies (FAVRES) is a measure of cognitive-communication and executive functions involving everyday tasks. Scores are predictive of employment status; however, the measure’s construct validity is unclear.Objective: The study’s objective was to assess the linear association of FAVRES test performance with performance on a number of neuropsychological measures in a sample of individuals with neurocognitive deficits.Methods: Twenty-two adults completed the FAVRES, Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Delis-Kaplan Executive Function System (D-KEFS), Color-Word Interference (CWI), Tower and Trail Making (TM).Results: FAVRES Total Accuracy score significantly correlated with CWI Inhibition (r = −0.43) and Tower (r = 0.60). Total Rationale significantly correlated with CWI Inhibition (r = −0.49), TM Number-Letter Switching (r = −0.48) and Tower (r = 0.55). Total Reasoning significantly correlated with CWI Inhibition (r = −0.71), Inhibition Switching (r = −0.50), TM Number-Letter Switching (r = −0.67) and Tower (r = 0.69) but also correlated with a number of measures involving other elements of cognition.Conclusion: Results provide evidence of convergent validity for the FAVRES as a measure of executive functions. Accuracy and Rationale scores also appear to have good discriminant validity.
