Differential response patterns on the Personality Assessment Inventory (PAI) in compensation-seeking and non-compensation-seeking mild traumatic brain injury patients
Published in
Journal of Clinical and Experimental Neuropsychology, December 2011
There is relatively little research on the Personality Assessment Inventory (PAI) with mild traumatic brain injury (MTBI) populations. There is also little research on how compensation-seeking status affects personality assessment results in MTBI patients. The current study examined the PAI scales and subscales in two MTBI groups, one composed of compensation-seeking MTBI patients and the other consisting of non-compensation-seeking MTBI patients. Results indicated significant differences on several scales and subscales between the two MTBI groups, with the compensation-seeking MTBI patients having significantly higher elevations on scales related to somatic preoccupation (Somatic Complaint Scale, SOM), emotional distress (Anxiety Scale, ANX; Anxiety Related Disorders Scale, ARD; Depression Scale, DEP), and the Negative Impression Management, NIM, validity scale. All the SOM subscales and the Anxiety Cognitive (ANX-C) and ANX Affective, ANX-A, subscales were also elevated in the compensation-seeking group. Results indicated that several scales on the PAI were sensitive to group differences in compensation-seeking status in MTBI patients.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 December 2011.
All research outputs
#17,286,645
of 25,374,917 outputs
Outputs from Journal of Clinical and Experimental Neuropsychology
#641
of 933 outputs
Outputs of similar age
#171,707
of 246,648 outputs
Outputs of similar age from Journal of Clinical and Experimental Neuropsychology
#10
of 16 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 933 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.6. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 246,648 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 19th percentile – i.e., 19% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
