Answer to Question 1
ANSWER:
Research indicates that depressive disorders may be due in part to biological factors like genetic predispositions as well as abnormal activity of specific neurotransmitters, abnormal functioning of the endocrine system, and the disruption of biological rhythms. A number of social-cognitive theories suggest that the way that people think about stressors affects the likelihood of depressive disorders. The theory of learned helplessness suggests that people experience depression as a result of feeling incapable of controlling their lives. Aaron Becks cognitive theory of depression suggests that depressed people develop mental habits of blaming themselves, focusing on the negative side of events, and jumping to pessimistic conclusions. A negative attributional style may be another important cognitive factor in depression and occurs when people blame their problems on a permanent, generalized lack of personal competence rather than on a temporary condition. Social-cognitive theorists also suggest that a ruminative style of dwelling on negative events can impact whether depression continues or worsens. Situational factors such as bad early relationships in childhood, lack of social support, and inadequate coping skills are also believed to play a role in the development of depressive disorders. However, it is usually a combination of interacting factors that lead to the cause of depressive disorders.
