Behavioural explanation of depression
- Reinforcement
- Lewinsohn (1974) proposed that depression occurs as a result of reduction in
positive reinforcement/rewards for doing good things.
- If the individual has poor social skills, they may find it very difficult to find alternative sources of positive reinforcement
- If the individual has poor social skills, they may find it very difficult to find alternative sources of positive reinforcement
- Links to the psychodynamic approach- important relationships are a key source of
positive reinforcement so a break in such a relationship can cause depression.
- When we lose these relationships that provide positive reinforcement, we stop getting
rewards so we stop doing positive things such as acting socially, and so we feel worthless.
- As we become inactive and our self esteem deteriorates, other people start to give us sympathy and attention and this
becomes our new 'positive reinforcement' so we start becoming more and more inactive so we get the 'reward' (attention).
- However, this results in the people giving us attention being pushed away and we feel start feeling unhappy and alienated.- it is a vicious cycle.

- Evaluation
- (S) Research does show that depressed people experience fewer positive reinforcements
than people who aren't depressed
- (W) Depression isn't always caused by loss of important people in our lives. A lot of the time, there is no reason
for the occurence of depression. This theory states that depression is indefinitely caused by loss.
- (W) Oversimplified view of
depression
- (W) Ignores compelling genetic evidence
- (S) Research does show that depressed people experience fewer positive reinforcements
than people who aren't depressed
- KEY STUDY: Lewinsohn et al (1990)
- AIM: To compare the amount of positive reinforcements received by depressed and
non-depressed patients
- METHOD: Sample=30 pps. There were a selection of depressed patients, patients with other disorders, and patients with no disorders. It
was a independent measures design quasi experiment.Through self-report, pps were given a 'pleasant events/positive reinforcement
schedule' and a 'depression adjective checklist', in which they had to tick adjectives that described their moods.
- RESULTS: There was a significant positive correlation between mood ratings and pleasurable events/positive reinforcement. Where there was less
reinforcement, moods were lower, and this was most typically found in depressed patients. Those who weren't depressed had many more
pleasurable events, suggesting they get a lot of positive reinforcement compared to depressed people who do not get as much rewards and so do
not do pleasurable activities. Therefore, mood dropped.
- CONCLUSION: Positive reinforcement is likely to be one of several factors influencing depression; less positive
reinforcement leads to less pleasurable activities, which leads to depressed mood.
- AIM: To compare the amount of positive reinforcements received by depressed and
non-depressed patients
