Cluster C personality disorders
Cluster C personality disorders are characterized by anxious, fearful thinking or behavior.
They include avoidant personality disorder, dependent personality disorder and obsessive-compulsive personality disorder.
It's not necessary to exhibit all the signs and symptoms listed for a disorder to be diagnosed.

Sex ratio: M=F
Comorbidity: Social phobia, depression, anxiety
Family: Cluster C disorders
Treatment
Psychotherapy - Individual and group therapy, typically interpersonal (IPT), is the treatment of choice
Medication - Antidepressants and anxiolytics are often useful for accompanying depression and anxiety
Physician-patient Interaction Unconditional respect and concern are very helpful
Avoid implications of rejection Be aware that even a limited personal interaction may be very important, and its loss very distressing
Dependent personality disorder
a strong need to be taken care of by other people. This need to be taken care of, and the associated fear of losing the support
of others, often leads people with Dependent Personality Disorder to behave in a "clingy" manner; to submit to the desires of other people.
