That is, friends and family ignore the individual after a brief period of grieving because they assume death has already occurred. Ultimately, the condition leads to damage to internal organs and death. Thus, from all accounts, an individual who is from a physical and psychological point of view functioning in a perfectly healthy and adaptive way suddenly dies because of marked changes in the social environment. GENDER Gender roles have a strong and sometimes puzzling effect on psychopathology The likelihood of your having a particular phobia is powerfully influenced by your gender. For example, someone who complains of an insect or small-animal phobia severe enough to prohibit field trips or visits to friends in the country is almost certain to be female, as are 90% of the people with this phobia (possible reasons for this were mentioned on pp. 62–63). But a social phobia strong enough to keep someone from attending parties or meetings affects men and women more or less equally but perhaps for different reasons. Bulimia nervosa, the severe eating disorder, occurs almost entirely in young females. A cultural emphasis on female thinness plagues our society and, increasingly, societies around the world. The pressures for males to be thin are less apparent, and of the few males who develop bulimia, a substantial percentage are gay; for these individu als, cultural imperatives to be thin are present in many specific instances (Rothblum, 2002). Our gender doesn’t cause psychopathology however gender role is a social and cultural factor that influences the form and content of a disorder pg. 11
