Document Summary
Cluster a: paranoid, schizoid, and schizotypal personality disorders (unusual behaviour, odd, eccentric) Cluster b: histrionic, narcissistic, antisocial, and borderline personality disorder (dramatic, emotional, erratic) Difficulties doing research on personality disorders: difficulties in diagnosing personality disorders. Diagnostic criteria for personality disorders are not as sharply defined as they are for other disorders. Clinician has to exercise a lot more judgment in making the diagnosis. Used semi-structured interviews and self-report inventories which has helped diagnostic reliability a lot. Different researchers often use different instruments and tend to come up with different diagnoses. Five factor model has been the most influential and helps researchers understand the commonalities and distinctions among different personality disorders: difficulties studying the causes of personality disorders. Only started receiving consistent attention since the 1980"s. Relativity little research has been conducted with most personality disorders. Vast majority of research is on people who already have the disorders so they don"t know what caused them, just that they have them.
