A series of behavioral expectation scale (BES)
applications were analyzed in an attempt to point
out an appropriate number of dimensions to be included
in such studies. Data from 4 independent
samples, representing 3 different occupations, and
incorporating a total of 436 multidimensional
evaluations were subjected to factor analysis. Results
reflected the lack of unique information contributed
when the number of dimensions exceeds 9.
The problem of lack of dimension independence
was discussed in terms of theory and application to
multidimensional performance evaluation. Suggestions
are advanced for limiting the number of
dimensions as a potential solution to information
