IntroductionDepression

• Depression is currently the fourth disorder worldwide in terms of disease burden

• It is expected to be the disorder with the highest disease burden in high-income countries by the year 2030

• Many studies have shown that stress is generated when a person appraises a situation as stressful or threating; and does not have proper coping response.

• A person who is well integrated in social networks is less vulnerable to stress or depression.

IntroductionThis Paper

In this paper, we extend an existing model for mood regulation to describe the different types of effect of social support on mood regulation.

The model involves different cognitive states of a human being that are considered as important for mood and appraisal of the situations

ModelHypotheses

1. Social support (both perceived and actual) leads to less negative mood.

2. A person who has a suitable social support will be more robust against bad events.

3. Perception that others will provide appropriate aids during bad events (perceived support) is more helpful than the actual support itself.

4. Social support can help people to learn how to cope with bad events. It means that at the very first times which a bad event happen, (s)he needs social support to cope with. But, after some successful experiences to handle the problem, (s)he will be more robust to cope with events with almost same demands.

Future Works

• Women have a higher rate of depression than man. Different process, different model.

• Investigate the relationships between measureable aspects of social environment (e.g. size and structure of a social network), and the factors used in the current model about the influence of social support on the cognitive states of a human.
