Validity and reliability of self-monitoring indices.
OBJECTIVE
This research concerns the measurement of self-monitoring in people who were diagnosed with traumatic brain injury (TBI), learning disability (LD) and emotional disorder (ED). Two measures of self-monitoring were evaluated: (1) the correlation between participants' self-predicted and observed standardized sub-test scores (R) on 17 WAIS-III 1 sub-tests and (2) the average difference between the participants' predicted and observed sub-tests scores (B). It was then determined if these measures could discriminate the three diagnostic groups.


METHODS
Canonical analysis assessed the relationship between the self-monitoring measures and four WAIS-III IQ measures. This study also evaluated if the R and B measures could discriminate the diagnostic groups.


METHODS
One hundred and twenty-four participants, 42 with TBI, 42 with LD and 40 with ED predicted their performance on 17 WAIS-III sub-tests.


RESULTS
Canonical analysis demonstrated a significant relationship between the R and B measures and four WAIS-III IQ measures. Results of a MANOVA showed that the R and B measures differed significantly among the diagnostic groups.


CONCLUSIONS
The R and B measures are two valid and reliable indices of self-monitoring that can be conveniently estimated from the WAIS-III.
