Further validation of the Orientation and Cognitive Logs: their relationship to the Mini-Mental State Examination.
OBJECTIVE
To further evaluate the construct validity of bedside screening measures of orientation (Orientation Log [O-Log]) and cognition (Cognitive-Log [Cog-Log]) by examining the relationship between these measures and the Mini-Mental State Examination (MMSE).


METHODS
Correlational analysis used to assess the degree of overlapping variance among the O-Log, Cog-Log, and MMSE. Qualitative item analysis used to assess strengths and weaknesses of the measures.


METHODS
Inpatient rehabilitation center affiliated with a large university medical school.


METHODS
Participants were 45 inpatients receiving neurorehabilitation.


METHODS
Not applicable.


METHODS
The O-Log, Cog-Log, and MMSE.


RESULTS
The MMSE correlated significantly with both measures (O-Log, r=.65, P<.001; Cog-Log, r=.75, P<.001). The O-Log and C-Log were significantly related to each other (r=.75, P<.001).


CONCLUSIONS
The results indicated good construct validity of the O-Log and Cog-Log. These measures may be better suited for a population with moderate to severe brain injury in a rehabilitation setting, compared with the MMSE, because scales were developed to give partial credit based on partially correct answers. Further, the O-Log and C-Log do not have a written component, allowing administration for persons with hemiparesis.
