This document discusses defense mechanisms, which are unconscious psychological mechanisms that help reduce anxiety from unacceptable stimuli. It surveys 100 students aged 18-24 on their use of various defense mechanisms in different situations. The survey found students most commonly use adaptive defense mechanisms like rationalization, displacement, regression, undoing and denial. They less frequently use maladaptive defenses like acting out, projection, and sublimation. The document aims to identify adaptive versus maladaptive uses of defenses and give examples of each. It details the survey methodology and responses. In summary, the document surveys college students' defense mechanism use and finds they more often employ adaptive rather than maladaptive strategies.
