People with callous–unemotional traits and also those with
autism spectrum disorder (ASD) display sociocognitive difficulties. However,
the frequency and neurocognitive correlates of callous–unemotional traits
within individuals with ASD are unknown.
Aims: To determine
the prevalence of callous–unemotional traits in individuals with ASD and test
their association with behavioural and cognitive measures.
Parents of 92 adolescents with ASD completed the Antisocial
Processes Screening Device (APSD) for callous–unemotional traits. Adolescents
participated in tasks of emotion recognition, theory of mind and cognitive
flexibility.
In total 51% (n = 47) scored above a cut-off expected to
identify the top 6% on the APSD. Of these 17% (n = 8) had concurrent conduct
problems. Regression analyses found callous–unemotional traits were associated
with specific impairment in fear recognition but not with theory of mind or
cognitive flexibility.
Adolescents with ASD show high rates of callous–unemotional
traits but, unlike in the general population, these are not strongly associated
with conduct problems. The relationship of callous–unemotional traits to
impairments in fear recognition suggests similar affective difficulties as in
individuals with callous–unemotional traits without ASD.
