The sample prevalence rates ranged from 0 to 21%, with the combined prevalence of 4.5% [95% CI (1.6, 7.9%)].

Prevalence and correlates of psychopathic traits in the household population of Great Britain. Sociopaths have two sides, the well-functioning and the less. Another interesting result of this work has to do with the finding of differences in the prevalence of psychopathy between different groups of adults in the general population. In fact, in this work, the number of subsamples/samples to examine gender prevalence was smaller than for calculating the overall prevalence. It's that some (high-functioning) sociopaths happen to have more skill than others, and thus the ability to do more damage. Psychol., 05 August 2021 Sec. This is because the personality and behavior of offenders with a diagnosis of psychopathy are very different from those of other offenders.

The results of the individual meta-regression analyses performed on the prevalence of the 16 samples of the general population indicated that the type of instrument [F(1, 14) = 5.24, p < 0.038, R2 = 0.17] and the type of sample [F(2, 13) = 4.96, p < 0.025, R2 = 0.52] significantly influenced the prevalence of psychopathy, but not the country of origin of the samples [F(2, 13) = 0.16, p = 0.857, R2 = 0.03].
