Document Summary

Etiology is the causal pattern of abnormal behavior. A necessary cause is a condition that must exist for a disorder to occur. A sufficient cause of a disorder is a condition that guarantees the occurrence of a disorder. Contributory causes increase the probability of the development of a disorder but is neither necessary nor sufficient for the disorder to occur. Some causal factors occur early in life and may not show their effects until later one distal causal factors. And other causal factors operate shortly before the occurrence of symptoms of a disorder and are considered proximal causal factors. A rienforcing contributory cause is a condition that tends to maintain maladaptive behavior that is already occurring. Protective factors are influences that modify a persons response to environmental stressors, making it less likely that the person will experience the adverse consequences of the stressors which can be individual personality traits or family environment, etc.
