Philosophers are continuously doing a research of the well-being. It is for the recent years, that the psychologists are also gaining interest in this sphere. The Subjective Well Being often abbreviated as SWB is the term which is used as an evaluation measure of the happiness. Subjective represents the feelings and the perception of the people. As you cannot measure the happiness by inserting a measuring stick in your brain, you will have to accept the perceptions of the other people. For the psychologists, well being can be a wider subject where the happiness can be medically interpreted.
The Subjective Well Being can be defined as the affective and the cognitive evaluation of the life of the individuals. The cognitive elements are those where the individuals can think about the satisfaction of his or her life in terms of global aspects, where he can consider the life as a whole or with some domain aspects, where he will specify the areas like relationships, work etc. The SWB is not about all the positives. It is also about the absence of the negative situations. The negative feelings like the anger and fright can reduce the subjective well being in an extensive manner. In the year 1984, Ed Diener has described the well being in three different aspects namely, the Life Satisfaction (LS), the Positive Affect (PA) and the Negative Affect (NA). Later, he also added another term, Domain Satisfaction (DS).
