The utility of the child and adolescent psychopathy construct in Hong Kong, China.

This cross-sectional study examined the nature of child and adolescent psychopathy using the Antisocial Process Screening Device (APSD) in 3,675 schoolchildren (ages 11-16) in Hong Kong, China. A confirmatory factor analysis observed a good fit for the three-factor model (callous-unemotional, impulsivity, narcissism) of APSD, with boys scoring higher than girls on narcissism and callous-unemotional traits. Modest construct validity was found with regard to expected relationships with internalizing and externalizing behavior problems. The previously observed higher scores on callous-unemotional traits in boys at older ages were replicated. Findings suggest that child psychopathy may be applicable in a non-Western culture, although the callous-unemotional factor may have a different meaning in China.
