it can be caused by Stressful events, Illness, Personality, Family history, Giving birth, Loneliness and also alcohol and drugs are contributed to depression.
The basic idea of behavioral theory is that everything amounts to behavior and inner processes are of little or no account. So if people feel miserable it is because of their behavior.
Changing peoples' behavior can have dramatic results but it is now known that people's perceptions and thought processes are also vitally important when overcoming depression.
Basically, the idea behind cognitive therapy is that people learn to 'catch' their thoughts and challenge them so that they can feel differently.
Recent studies of how the brain works have shown that certain emotions occur before thoughts and it is possible to be afraid of something before we can think what it is. However cognitive therapy, if applied skillfully, has done very well in the research for lifting and preventing relapse of depression.
This approach focuses on the way people relate with other people in their lives - how they communicate and express themselves. Whether a person is assertive, aggressive or timid or has 'social skills' is seen as key.
Depression can cause us to lose access to the skills and the desire to sustain these relationships successfully.
Whether it be feelings of wanting to be alone, not knowing what to say, or just feeling wretched and not wanting to be in company, a large percentage of depression sufferers exhibit what is crudely called "poor social skills"
As it's name suggests, the emphasis here is on finding solutions to current problems and focusing on future wellness rather than past hurts. This is not to say that the past is ignored but the main emphasis is on teaching new skills and keeping therapy brief and focused.
