The following tests can be used in the diagnosis of personality disorders:
- Toxicology screen - Substance abuse is common in many personality disorders, and intoxication can lead patients to present with some features of personality disorders.
- Screening for HIV and other sexually transmitted diseases - Patients with personality disorders often exhibit poor impulse control, and many act without regard to risk; such behavior can lead to infection with a sexually transmitted disease
- CT Scanning - Computed tomography (CT) scanning with appropriate blood work can be carried out if organic etiology is suspected
- Radiography - Radiography can be indicated for injuries from fighting, motor vehicle accidents, or self-mutilation
Psychological testing may support or direct the clinical diagnosis.[11, 9] The Minnesota Multiphasic Personality Inventory (MMPI) is the best-known psychological test. The Eysenck Personality Inventory and the Personality Diagnostic Questionnaire are also used. None of these has been reliably validated against DSM-5 diagnoses.
The Structured Clinical Interview for DSM-5 (SCID-5) can also be used to aid in diagnosis.
