Cognitive Log performance among individuals without brain injury in an inpatient rehabilitation setting.

Purpose/objective: Despite the widespread use of the Cognitive Log, information regarding normative performance is only available in individuals with known brain injury and in healthy college students. The purpose of the current research is to provide information about Cognitive Log performance in a regional group of rehabilitation patients without history of brain injury. Secondarily, non-neurological factors that may predict performance are considered. Research Method/Design: Participants included in this study were 121 consecutive patients admitted to an inpatient rehabilitation hospital spinal cord and orthopedic floor. Based on history, only patients without insult to the brain were included.

Results: This study provides normative information for Cognitive Log performance in a nonbrain injured population, showing that these patients score in between those with acquired brain injury and healthy controls. Variables including age, estimated intelligence, and self-reported pain, fatigue, and affective distress accounted for 47.5% of the variance in Cognitive Log scores, although age and estimated intelligence, which accounted for 43.3% of the variance, were the only individually significant contributors to performance.

Conclusions/implications: This study provides an estimate of normative Cognitive Log performance in a nonbrain injured population. This information is especially useful in that it signifies that both neurological and non-neurological factors contribute to Cognitive Log performance, and this information may shape how clinicians conceptualize scores in patients with and without brain injury. Age and longstanding intellectual abilities should be taken into consideration when interpreting Cognitive Log performances, developing rehabilitation strategies, and determining need for additional testing.
