Final answer:
Impulsivity and perfectionism are the two main personality risk factors for eating disorders, often interacting with environmental factors to increase risk.
Step-by-step explanation:
The two main personality risk factors associated with eating disorders are impulsivity and perfectionism. Individuals who exhibit high levels of impulsivity may engage in disordered eating as a way to cope with emotional distress or to seek immediate reward without considering long-term consequences. On the other hand, those who strive for perfectionism may develop eating disorders like anorexia nervosa or bulimia nervosa in an effort to achieve an idealized body image or to maintain a sense of control. It's important to note that these personality traits interact with a variety of environmental factors such as childhood abuse, parental control over eating habits, cultural ideals of thinness, and social isolation, which can further increase the risk of developing eating disorders.
