  • Penna S, Novack TA. 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). Design: 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. Setting: Inpatient rehabilitation center affiliated with a large university medical school. Participants: Participants were 45 inpatients receiving neurorehabilitation. Interventions: Not applicable. Main Outcome Measures: 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. © 2007 American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.
