psychometric characteristics of the career beliefs inventory
xiii, 247 leaves : illustrations ; 28 cm.
The Career Beliefs Inventory (CBI) is a 96-item career
development measure yielding scores on 25 scales. The
purpose of the present study was to evaluate the psychometric
characteristics of CBI scores. Specifically, the following
psychometric characteristics of the CBI were evaluated: (a)
scale alpha coefficients and item analysis statistics, (b)
confirmatory structure, and (c) exploratory first- and
secondorder factor structures. The present study involved the
use of three data sets. One data set included the
standardization sample obtained from the CBI author
(n=1,788). The other two data sets (n,=344, n2=251) were
collected by the author for the purposes of the present
study. Evaluation of the psychometric characteristics of the
CBI was done through a series of analyses. Results of
internal consistency analyses for the scores from the 25 CBI
scales, as well as the scores created using the scoring keys
associated with the first-order factors reported in the
manual, ranged from lows in the .30's to highs in the .80's,
with a mean coefficient alpha of .567 for CBI scale scores.
Consequently, the item make-up for a majority of the CBI
scales needs to be re-evaluated. For the confirmatory
structure analyses, six substantive models were fit to the
data. None of the models resulted in a good fit to the data.
Therefore, focus for further examination of the CBI shifted
to exploratory first- and second-order factor analyses.
Exploratory first-order factor analyses of the scores from
the 96 item CBI resulted in a six-factor structure.
Exploratory second-order factor analyses of two data sets
(CBI Sample and Pooled Sample) resulted in four-factor
solutions that were generally similar, with two of the four
factors in both data sets being readily comparable. The
following recommendations were based on the findings of the
present study. With few items per scale and low
reliabilities, practical application of the CBI may involve
exploration of beliefs using items as a basis for discussion,
as against using actual scale or item scores. Further
evaluation of the psychometric properties of the CBI and of
alternative models also appears to be warranted.
