| dc.description.abstract | The present study compared a random version of the Beck
Depression Inventory II (BDI-IIR, based on the work of
Dahl Strom, Brooks, & Peterson, 1990) with the standard
version in a sample of 139 university students. The study
also assessed various psychometric properties of the Random
version, including test-retest reliability, internal
consistency, discriminant validity, and concurrent validity
using the standard BDI-II, the Zung Self-Rating Scale (SRS) ,
and the Center for Epidemiological Studies-Depression Scale
(CES-D) over a two week period. In addition, the effects of
prior exposure to a depression inventory were examined. The
BDI-II and its random counterpart did not evidence
significantly different total scores, and both were found to
have adequate and similar test-retest reliability, internal
consistency and validity. Test-retest reliability was .86
for the BDI-II and .75 for the BDI-IIR. Internal
consistency was found to be .87 and .85 for the BDI-II and
BDI-IIR respectively. Both versions of the BDI-II were
found to possess adequate validity with the CES-D and SRS.
However, both scales also correlated very highly with the
Edwards Social Desirability Scale. Lastly, pre-exposure to
depression measures did not result in decreased scores at a
later administration. | |
