Evaluation of the TriPM and PPI using the CAPP as a concept map in Canadian and Dutch samples

CONCEPTULIZATION

Traits of Psychopathic Personality Disorder:  are heterogeneous  are complex  are ‘continuous’ not ‘categorical’  change overtime  mimicked by other conditions  differ in expression across gender, age & culture  inherently contradict self-report  in youth?

Psychopathy is a personality disorder.

CONCLUSIONS: GLOBAL ANALYSIS

• 1. Total scores on both tests were correlated with total

scores on the CAPP and moderately to highly correlated with all the CAPP domains.

• 2. Total scores were also correlated negatively with CAPP

Foils, indicating they are specifically associated to PPD.

SFU Psychology

CONCLUSIONS: FINE GRAINED ANALYSIS

However, consistent with past research:

• 1. Total scores were more highly correlated with the

behavioral domains than any other CAPP domain

• 2. PPI Factor 1 and Boldness had different patterns of

correlations that the other domains, this different across the two samples

• 1. PPI Factor 1 had a different pattern in the

Canadian sample, but not in the Dutch sample

• 2. Boldness had a different pattern of correlation in

both samples Self-report measures exhibited some important limitations
