I can't seem to find a decent explination about the concept of Primary and Secondary psychopathy. Can anyone clear this up, please?
Oh, and if anyone has any info on "Fractured Identity Syndrome" I'll be grateful.
On the MMPI-2 Restructured Clinical Scales (RC), primary psychopathy (as measured by the Psychopathic Personality Inventory, Factor 1) is negatively correlated with RC2 (low positive emotions), RC7 (dysfunctional negative emotions), RC4 (antisocial behavior), and RC9 (hypomanic activation). On the MMPI-2 Personality Psychopathology Five (PSY-5) scales, primary psychopathy was positively correlated with aggression (Specifically, grandiosity and interpersonal dominance, and instrumental aggression). and DISC(onstraint) (specifically, fearlessness) while being negatively correlated with NEGE (negative emotionality) and INTR(oversion).
Newman et al. found measures of primary psychopathy to be negatively correlated with Gray's behavioral inhibition system, a construct intended to measure behavioral inhibition from cues of punishment or nonreward.
 Secondary psychopathy
Secondary psychopaths show normal to above-normal physiological responses to (perceived) potential threats. Their crimes tend to be unplanned and impulsive with little thought of the consequences . They have hot tempers and are prone to reactive aggression. They experience normal to above-normal levels of anxiety but are nevertheless highly stimulus seeking and have trouble tolerating boredom. Their lifestyle may lead to depression and even suicide.
For the secondary psychopath especially prominent are the Factor 2 (in the two-factor model) PCL-R items of impulsivity, weak behavioral controls, irresponsibility, lack of realistic long-term goals, proneness to boredom/need for stimulation, parasitic lifestyle, early behavioral problems, juvenile delinquency, and revocation of conditional release (breaking probation).
Sellbom and Ben-Porath (2005) found that secondary psychopathy (as measured by the Psychopathic Personality Inventory, Factor 2) shows opposite correlations to primary psychopathy in many cases. On the MMPI-2 RC, secondary psychopathy is positively correlated with RC4 (asb), RC7 (dne), and RC9 (hpm). It was also found to be correlated with the MMPI-2 PSY-5 scales of AGGR(ession) and DISC(onstraint).
Newman et al. found measures of secondary psychopathy to be positively correlated with Gray's behavioral activation system, a construct intended to measure sensitivity to cues of behavioral approach.
