Document Summary
Advantages of categories familiar: some limited treatment recommendations facilitates quick communication. Capture complex person in single word/sentence: traditional (medical disease model) Limitations of categorical model: high rates of co-occurrence. When a person has one they are possible to have more: heterogeneity within one disorder. Most prevalent disorder in clinical practice: personality disorder not otherwise specified (psdnos) Half the people of the half the people who have a personality disorder have pdnos: arbitrary cut-offs to define cases. Boundary with normality: lack of underlying theory or scientific foundation, clinicians dissatisfaction. Dimensional perspective: personality disorders are maladaptive, extreme versions of normal personality traits, factor analysis look at the factors around something and sort them into things that are alike. The personality disorder all fall under the similar categories as the general personality traits: everyone has general personality traits, but the extremes are what are considered the disorders/problematic, advantages. Covers virtually all forms of pd (no pdnos)
