ii) affectivity (range, intensity and appropriateness of emotional arousal and response)
iii) control over impulses and gratification of needs
iv) manner of relating to others and of handling interpersonal situations

2. The deviation must manifest itself pervasively as behaviour that is inflexible, maladaptive, or otherwise dysfunctional across a broad range of personal and social situations
3. There is personal distress, or adverse impact on the social environment, or both
4. There must be evidence that the deviation is stable and of long duration, having its onset in late childhood or adolescence
5. The deviation cannot be explained as a manifestation or consequence of other adult mental disorders
6. Organic brain disease, injury, or dysfunction must be excluded as the possible cause of the deviation
