Test-retest reliability and factor stability of the behavioral evaluation for epidemiology studies test battery

The Behavioral Evaluation for Epidemiology Studies test battery uses touch-screen technology and novel methodologies to enhance neurobehavioral assessment. Scores generally show differential stability from the first trial with individual test reliabilities at or above .80 when normalized to a 3-min. administration. Six highly reliable (r > or = .87) factors were identified that cover functions known to be sensitive to neurotoxicants and physical exposures. These results strongly support recommendation of the new test battery for use in repeated-measures epidemiologic studies where first trial stability is desired.
