Dependent personality disorder (DPD) is a personality disorder, marked by feelings of helplessness, submissiveness, a need to be taken care of and for constant reassurance, and an inability to make everyday decisions without an excessive amount of advice and reassurance from others.
DPD appears to occur equally in men and women, and usually appears in early to middle adulthood.
What Are the Symptoms of DPD?
People with DPD become overly emotionally dependent on other people and spend great effort trying to please others. People with DPD tend to display needy, passive, and clinging behavior, and have a fear of separation. Other common characteristics of this personality disorder include the following:
- Inability to make decisions, even everyday decisions, without the advice and reassurance of others
- Avoidance of personal responsibility; avoidance of jobs that require independent functioning and positions of responsibility
- Intense fear of abandonment and a sense of devastation or helplessness when relationships end; A person with DPD often moves right into another relationship when one ends.
- Over-sensitivity to criticism
- Pessimism and lack of self-confidence, including a belief that they are unable to care for themselves
- Avoidance of disagreeing with others for fear of losing support or approval
- Inability to start projects
- Difficulty being alone
- Willingness to tolerate mistreatment and abuse from others
- Placing the needs of their caregivers above their own
- Tendency to be naive and to live in fantasy
What Causes DPD?
Although the exact cause of DPD is not known, it most likely involves both biological and developmental factors. Some researchers believe an authoritarian or overprotective parenting style can lead to the development of dependent personality traits in people who are susceptible to the disorder.
How Is DPD Diagnosed?
If symptoms of DPD are present, the doctor will begin an evaluation by performing a complete medical history and physical exam. Although there are no lab tests to specifically diagnose personality disorders, the doctor might use various diagnostic tests to rule out physical illness as the cause of symptoms.
If the doctor finds no physical reason for the DPD symptoms, he or she might refer the person to a psychiatrist or psychologist, health care professionals who are specially trained to diagnose and treat mental illnesses. Psychiatrists and psychologists use specially designed interview and assessment tools to evaluate a person for a personality disorder.
