Abstract
Pre- and posttreatment data from a treatment study utilizing Bandura's 18-item behavioral approach test (BAT)for fear of snakes were analyzed to assess the scalability of behavior and self-efficacy scores. Coefficients of reproducibility ranged from .97 to .99, indicating that measures of behavior and self-efficiacy on this BAT constitute valid Guttman scales. Bandura's (1980)method of calculating expected concordance rates is not valid for Guttman scales because all possible patterns of response produce observed concordance rates that are equal to or greater than expected rates it generates. The concordance rate between the items on Guttman scales are completely determined by the total score on each scale. Therefore, “microanalyses” of concordance rates between efficacy and behavior on BATs are redundant. Researchers using other dependent variable measures should determine the coefficients of reproducibility of their scales prior to reporting item-by-item concordance rates.
