Depression is amood disorderthat prevents individuals from leading a normal life at work, socially, or within their family. Seligman (1973) referred to depression as the ‘common cold’ of psychiatry because of its frequency of diagnosis.
Depending on how data are gathered and how diagnoses are made, as many as 27% of some population groups may be suffering from depression at any one time (NIMH, 2001; data for older adults).
Behaviorist Theory
Behaviorismemphasizes the importance of the environment in shaping behavior. The focus is on observable behavior and the conditions through which individuals” learn behavior, namely classical conditioning, operant conditioning, and social learning theory.
Therefore, depression is the result of a person’s interaction with their environment.
For example,classical conditioningproposes depression is learned through associating certain stimuli with negative emotional states.Social learning theorystates behavior is learned through observation, imitation, and reinforcement.
Operant Conditioning
For example, when a loved one is lost, an important source of positive reinforcement has lost as well. This leads to inactivity. The main source of reinforcement is now the sympathy and attention of friends and relatives.
However, this tends to reinforce maladaptive behavior, i.e., weeping, complaining, and talking of suicide. This eventually alienates even close friends leading to even less reinforcement and increasing social isolation and unhappiness. In other words, depression is a vicious cycle in which the person is driven further and further down.
Also, if the person lacks social skills or has a very rigid personality structure, they may find it difficult to make the adjustments needed to look for new and alternative sources of reinforcement (Lewinsohn, 1974). So they get locked into a negative downward spiral.
Critical Evaluation
Behavioral/learning theories make sense in terms of reactive depression, where there is a clearly identifiable cause of depression. However, one of the biggest problems for the theory is that of endogenous depression. This is depression that has no apparent cause (i.e., nothing bad has happened to the person).
An additional problem of the behaviorist approach is that it fails to consider cognitions (thoughts) influence on mood.
Psychodynamic Theory
During the 1960s, psychodynamic theories dominated psychology and psychiatry. Depression was understood in terms of the following:
Freud’spsychoanalytic theoryis an example of thepsychodynamic approach. Freud (1917) proposed that many cases of depression were due to biological factors.
However, there is an important difference because depressed people regard themselves as worthless. What happens is that the individual identifies with the lost person so that repressed anger towards the lost person is directed inwards towards the self. The inner-directed anger reduces the individual’sself-esteemand makes him/her vulnerable to experiencing depression in the future.
Later, Freud modified his theory stating that the tendency to internalize lost objects is normal and that depression is simply due to an excessively severe super-ego. Thus, the depressive phase occurs when the individual’ssuper-egoor conscience is dominant. In contrast, the manic phase occurs when the individual’s ego or rational mind asserts itself, and s/he feels control.
In order to avoid loss turning into depression, the individual needs to engage in a period of mourning work, during which s/he recalls memories of the lost one.
This allows the individual to separate himself/herself from the lost person and reduce inner-directed anger. However, individuals very dependent on others for their sense of self-esteem may be unable to do this and so remain extremely depressed.
Psychoanalytic theories of depression have had a profound impact on contemporary theories of depression.
Another criticism concerns the psychanalytic emphasis on the unconscious, intrapsychic processes, and early childhood experience as being limiting in that they cause clinicians to overlook additional aspects of depression. For example, conscious negative self-verbalization (Beck, 1967) or ongoing distressing life events (Brown & Harris, 1978).
Cognitive Explanation of Depression
This approach focuses on people’s beliefs rather than their behavior. Depression results from systematic negative bias in thinking processes.
Emotional, behavioral (and possibly physical) symptoms result from cognitive abnormality. This means that depressed patients think differently from clinically normal people. Thecognitive approachalso assumes changes in thinking precede (i.e., come before) the onset of a depressed mood.
Beck’s (1967) Theory
One major cognitive theorist is Aaron Beck. He studied people suffering from depression and found that they appraised events in a negative way.
Beck (1967) identified three mechanisms that he thought were responsible for depression:
Thecognitive triadis three forms of negative (i.e., helpless and critical) thinking that are typical of individuals with depression: namely, negative thoughts about the self, the world, and the future. These thoughts tended to be automatic in depressed people as they occurred spontaneously.
For example, depressed individuals tend to view themselves as helpless, worthless, and inadequate. They interpret events in the world in an unrealistically negative and defeatist way, and they see the world as posing obstacles that can’t be handled.
Finally, they see the future as totally hopeless because their worthlessness will prevent their situation from improving.
As these three components interact, they interfere with normal cognitive processing, leading to impairments in perception, memory, and problem-solving, with the person becoming obsessed with negative thoughts.
Beck believed that depression-prone individuals develop anegative self-schema. They possess a set of beliefs and expectations about themselves that are essentially negative and pessimistic. Beck claimed that negative schemas might be acquired in childhood as a result of a traumatic event. Experiences that might contribute to negative schemas include:
However, a negative self-schema predisposes the individual to depression, and therefore someone who has acquired a cognitive triad will not necessarily develop depression.
Some kind of stressful life event is required to activate this negative schema later in life. Once the negative schema is activated, a number of illogical thoughts orcognitive biases seem to dominate thinking.
People with negative self-schemas become prone to makinglogical errorsin their thinking, and they tend to focus selectively on certain aspects of a situation while ignoring equally relevant information.
Beck (1967) identified a number of systematic negative biases ininformation processingknown as logical errors or faulty thinking. These illogical thought patterns are self-defeating and can cause great anxiety or depression for the individual.For example:
When a person’s stream of automatic thoughts is very negative, you would expect a person to become depressed. Quite often these negative thoughts will persist even in the face of contrary evidence.
Alloy et al. (1999) followed the thinking styles of young Americans in their early 20s for six years. Their thinking style was tested, and they were placed in either the ‘positive thinking group’ or ‘negative thinking group’.
After six years, the researchers found that only 1% of the positive group developed depression compared to 17% of the ‘negative’ group. These results indicate there may be a link between cognitive style and the development of depression.
However, such a study may suffer from demand characteristics. The results are also correlational. It is important to remember that the precise role of cognitive processes is yet to be determined. The maladaptive cognitions seen in depressed people may be a consequence rather than a cause of depression.
Learned Helplessness
Martin Seligman (1974) proposed a cognitive explanation of depression calledlearned helplessness.
According to Seligman’s learned helplessness theory, depression occurs when a person learns that their attempts to escape negative situations make no difference.
Consequently, they become passive and will endure aversive stimuli or environments even when escape is possible.
Seligman based his theory on research using dogs.
A dog put into a partitioned cage learns to escape when the floor is electrified. If the dog is restrained whilst being shocked, it eventually stops trying to escape.
Dogs subjected to inescapable electric shocks later failed to escape from shocks even when it was possible to do so. Moreover, they exhibited some of the symptoms of depression found in humans (lethargy, sluggishness, passive in the face of stress, and appetite loss).
The depression attributional style is based on three dimensions, namelylocus(whether the cause is internal – to do with a person themselves, or external – to do with some aspect of the situation),stability(whether the cause is stable and permanent or unstable and transient) andglobalorspecific(whether the cause relates to the “whole” person or just some particular feature characteristic).
In this new version of the theory, the mere presence of a negative event was not considered sufficient to produce a helpless or depressive state. Instead, Abramson et al. argued that people who attribute failure to internal, stable, and global causes are more likely to become depressed than those who attribute failure to external, unstable, and specific causes.
This is because the formerattributional styleleads people to the conclusion that they are unable to change things for the better.
This suggests that helplessness could be a symptom rather than a cause of depression. Moreover, it may be that negative thinking generally is also an effect rather than a cause of depression.
Humanist Approach
Humanistsbelieve that there are needs that are unique to the human species. According toMaslow(1962), the most important of these is the need forself-actualization(achieving our potential). The self-actualizing human being has a meaningful life. Anything that blocks our striving to fulfill this need can be a cause of depression. What could cause this?
