Investigating error-related processing in incarcerated adolescents with self-report psychopathy measures
Section snippets
Participants
Participants included n = 142 incarcerated adolescent offenders recruited from a maximum security juvenile correctional facility who participated in a larger study (Southwest Advanced Neuroimaging Cohort − Youth (SWANC-Y)). Participants were excluded from analyses for meeting the following criteria: previous history of traumatic brain injury accompanied with a significant loss of consciousness (n = 4), significant movement during data collection, or behavioral performance (i.e., making less than
Behavioral results
Response times (RTs) and frequency for Hits and FA’s were analyzed and have been previously reported (Maurer, Steele and Cope et al., 2016). As expected, participants responded faster to NoGo stimuli (M = 381 ms, SD = 43 ms) than Go stimuli (M = 419 ms, SD = 51 ms), t(99) = 7.74, p < 0.001. Participants made significantly more errors (i.e., FA’s) to NoGo stimuli (M = 23.76, SD = 11.85) compared to Go stimuli (M = 12.61, SD = 14.65), t(99) = 17.89, p < 0.001. For the full sample, there was a main effect of post-error
Discussion
Psychopathic traits in youth samples are typically measured using either interview-based or self-report measures. Evidence suggests however, that these assessments should not be used interchangeably, as evidenced by poor classification agreement between measures (Cauffman et al., 2009, Fink et al., 2012, Lee et al., 2003, Skeem and Cauffman, 2003). Additionally, self-report measures of adolescent psychopathic traits show poor predictive utility of delinquency and antisocial indices compared to
Conclusions
In sum, scores on measures of adolescent psychopathic traits (i.e., Total and Factor scores from the APSD, CPS, ICU, and YPI) were not associated with ERN/Ne or Pe dysfunction, measured with traditional time-domain ERP or PCA analyses. Such results are inconsistent with a previous report from our laboratory, whereby PCL:YV Total and Facet 4 scores were negatively related to Pe amplitude within the same sample of n = 100 incarcerated male adolescent offenders (Maurer, Steele and Cope et al., 2016
