This is a persistent problem, and not a passing one, lasting on an average 6 to 8 months, affecting the quality of life of an individual.
The causes of depression are multifaceted :
- biological ( changes in the neurotransmitter level of the brain)
- environmental or psychosocial.
Some people are at a higher risk of depression due to life events like bereavement, divorce, work issues family and financial problems, or simply due to acute stress.
Childhood trauma, some prescription drugs, (steroids), and recreational drugs like alcohol or amphetamines are strongly linked to depression.
Chronic pain syndrome, and conditions like diabetes, and cardiovascular diseases can also make a person depression prone.
The Cognitive Triad is a cognitive model developed by Aaron Beck to describe the cause of depression.
He proposed that three types of negative thoughts lead to depression:
- thoughts about the self,
- thoughts about the world/environment,
- thoughts about the future.
People suffering from depression will attribute negative and unpleasant events to their personal failings (self) and to the unfair and unforgiving world.
The future is perceived to be bleak and devoid of hope with their troubles lasting forever.
“Helplessness and worthless” are the dominant feelings in a person suffering from depression.
Components of this cognitive triad often feed and strengthen each other.
No wonder , being so focused on the negatives , a depressed person ,when asked to share “what is going good in your life?’’ cannot find an appropriate answer.
Beck developed a cognitive explanation of depression which has three components:
- cognitive bias
- negative self-schemas
- the negative triad.
1) Cognitive Bias/ Cognitive Distortions
Beck found that depressed people are more likely to focus on the negative aspects of a situation, while ignoring the positives.
They are prone to distorting and misinterpreting information, a process known as cognitive bias or cognitive distortions Beck (1967) identifies a number of illogical thinking processes (i.e. distortions of thought processes). These illogical thought patterns are self-defeating, and can cause great anxiety or depression for the individual.
1. Arbitrary interference:
Drawing conclusions on the basis of sufficient or irrelevant evidence: for example, thinking you are worthless because an open air concert you were going to see has been rained off.
2. Selective abstraction:
Focusing on a single aspect of a situation and ignoring others: E.g., you feel responsible for your team losing a football match even though you are just one of the players on the field.
exaggerating the importance of undesirable events. E.g., if you scrape a bit of paintwork on your car and, therefore, see yourself as a totally awful driver.
underplaying the significance of an event. E.g., you get praised by your teachers for an excellent term’s work, but you see this as trivial.
drawing broad negative conclusions on the basis of a single insignificant event. E.g., you get a D for an exam when you normally get straight As and you, therefore, think you are stupid.
Attributing the negative feelings of others to yourself. E.g., your teacher looks really cross when he comes into the room, so he must be cross with you.
