Furthermore, they suggested that members of the VDT would be positively correalted with problems with regulating emotions, psychopathology and negative emotionality but negatively correlated with positive emotions and self-esteem. Furthermore, they suggested that VDT would be positively correlated with anxious and avoidant attachment styles.
They predicted that secondary psychopathy and BPD would involve externalizing behaviors such as abuse of romantic partners, drug abuse, non-suicidal self-harm, crime and gambling, but that this would be less true of vulnerable narcissism.
They also emphasize the importance of differentiating F1 narcissism from vulnerable narcissism. They predict that The F1 narcissism of DT, 'grandiose' narcissism, would be negatively correlated with neuroticism and internalization behaviors and traits such as depression, distress and anxiety, and positively correlated with extraversion and self-esteem.
They furthermore suggested that there would be little or no correlation of such tendencies with parental styles, perhaps reflecting the consensus among specialists in primary psychopathy that primary psychopathy has primarily genetic, rather than environmental, causes. Both forms of narcissism, however, would be likely to exhibit low degrees of agreeableness.
They also suggest that F1 or primary psychopathy would likely fall between VDT and TD 'grandiose' narcissism, exhibiting low levels of agreeableness and conscientiousness but low or 'null' correlations with neuroticism (neither positive like those of VDT vulnerable narcissism, nor negative like those of TD grandiose narcissism).
They also predicted that F1 psychopathy would demonstrate positive but somewhat weaker correlations with psychopathology and impulsivity than VDT, and null correlations with less than ideal environmental factors.
