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 greater than or equal to .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.
