Document Summary

When personality style has become rigid and maladaptive it may be considered a pd. Differentiating between traits and disorders is crucial for diagnosis and treatment. Personality disorders should never be diagnosed after a single brief behavioural observation because they represent enduring ways of dealing with the world: should not diagnose pds without knowing the surrounding context. 3 ps patterns of maladaptive functioning behaviour: persistent (over time; long-term, chronic, pervasive (over people and situations, pathological (clearly abnormal) 3 clusters: odd or eccentric, dramatic, emotional, or erratic, anxious or fearful. Dsm follows the categorical model: categorical model of personality: one either has or does not have a particular pd, dimensional model of personality: full range of a trait which considers personality to be on a continuum. Similar features to those seen in psychosis and schizophrenia: family members of someone with schizophrenia have higher rates of cluster a pds.
