Disorder-specific Tests

There are dozens of psychological tests that are disorder-specific: they aim to diagnose specific personality disorders or relationship problems. Example: the Narcissistic Personality Inventory (NPI) which is used to diagnose the Narcissistic Personality Disorder (NPD).

The Borderline Personality Organization Scale (BPO), designed in 1985, sorts the subject's responses into 30 relevant scales. These indicates the existence of identity diffusion, primitive defenses, and deficient reality testing.

Other much-used tests include the Personality Diagnostic Questionnaire-IV, the Coolidge Axis II Inventory, the Personality Assessment Inventory (1992), the excellent, literature-based, Dimensional assessment of Personality Pathology, and the comprehensive Schedule of Nonadaptive and Adaptive Personality and Wisconsin Personality Disorders Inventory.

Having established the existence of a personality disorder, most diagnosticians proceed to administer other tests intended to reveal how the patient functions in relationships, copes with intimacy, and responds to triggers and life stresses.

The Relationship Styles Questionnaire (RSQ) (1994) contains 30 self-reported items and identifies distinct attachment styles (secure, fearful, preoccupied, and dismissing). The Conflict Tactics Scale (CTS) (1979) is a standardized scale of the frequency and intensity of conflict resolution tactics and stratagems (both legitimate and abusive) used by the subject in various settings (usually in a couple).

The Multidimensional Anger Inventory (MAI) (1986) assesses the frequency of angry responses, their duration, magnitude, mode of expression, hostile outlook, and anger-provoking triggers.

Yet, even a complete battery of tests, administered by experienced professionals sometimes fails to identify abusers and their personality disorders. Offenders are uncanny in their ability to deceive their evaluators.
