- Summary:
-
This study focused on the issue of measurement reliability and its attenuation on correlation between two composites and two seemingly different approaches for correcting the attenuation. As expected, Monte Carlo simulation results show that correlation coefficients uncorrected for measurement error are systematically biased downward. For the data conditions examined, the two correction approaches provided not only nearly identical and unbiased means, but also near identical confidence intervals for the sampling distribution of the corrected correlation coefficients. The highly comparable results suggest that these two approaches work equally well for these data. It is pointed out that the confirmatory factor analysis modeling approach may be less applicable because of more difficult data conditions at the item level in research practice. The findings point to the importance of reporting measurement reliability information whenever possible. The findings further suggest that correction for attenuation be considered when information about score reliability is available. (Contains 2 tables, 5 figures, and 14 references.) (Author/SLD)
