This study examined the construct of psychopathy using the Psychopathy Checklist-Revised (PCL-R) in 54 participants from the general population. To obtain a sample of community participants with psychopathic characteristics, participants were recruited using advertisements for a "personality study" that incorporated the characteristics of psychopathy in a nonpejorative manner. The methodology successfully recruited community participants with moderately elevated PCL-R scores. Participants exhibited the personality features of psychopathy (Factor 1) to a greater extent than the behavioral features (Factor 2), which is consistent with the results obtained with the PCL-R normative samples. Roughly 40% of the sample reported no history of involvement with the criminal justice system, yet these participants exhibited moderately elevated PCL-R scores. Moreover, a sizeable portion of the noncriminal participants reported a substantial history of violent behavior. Comparisons of PCL-R scores between participants with and without a criminal history suggest that these two groups differ in ways unrelated to criminal justice system involvement.
This research output has an Altmetric Attention Score of 13. 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 14 December 2025.
All research outputs
#3,572,867
of 33,779,198 outputs
Outputs from Behavioral Sciences & the Law
#152
of 896 outputs
Outputs of similar age
#9,722
of 122,317 outputs
Outputs of similar age from Behavioral Sciences & the Law
#5

Altmetric has tracked 33,779,198 research outputs across all sources so far. Compared to these this one has done well and is in the 89th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 896 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 12.0. This one has done well, scoring higher than 83% of its peers.
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 122,317 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 91% of its contemporaries.
We're also able to compare this research output to 70 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 92% of its contemporaries.
