Briefly outline the evidence for genetic and environmental contributions to personality disorders. Identify the specific experiences that seem to underlie personality disorders. Which personality disorder seems the MOST genetic?
What will be an ideal response?
Ans: Heritability estimates for the personality disorders range from about 0.40 to about 0.60, suggesting both genetic and environmental contributions to the disorders. Borderline personality disorder seems to be the only one that is more genetic than environmental. Emotional abuse, sexual abuse, and neglect are related to the later development of personality disorders. In one study (Battle et al., 2004), three quarters or more of a sample of participants with personality disorders had experienced childhood abuse or neglect.
