The conceptualization of emotional intelligence has evolved to include the ability to recognize emotions, to generate and reason them, to understand them, and to reflectively regulate emotions in oneself and in others (Mayer and Salvory, 1997).

Here is a popular article on the results of teaching EI in schools:

There are also reports of successful interventions for older adolescents in universities (see http://www.sciencedirect.com/science/article/pii/S1041608012000192. Lorraine is also on researchgate so you could get the paper from her). There's some interesting work on the UK Government's social and emotional learning interventions with primary and secondary school pupils (see researchgate pages for Neil Humphrey, University of Manchester). The stories are interesting.

There are several EI models that are being 'taught'. I subscribe (and used it for my doctoral dissertation) to Bar-On's model which includes decision making and stress management. To improve one's EI takes a conscious effort and at times is not easy; having said that when one EI area improves, it often affects other EI areas (usually in a positive manner).

Armstrong (2009) wrote:

"Emotional intelligence is a combination of skills and abilities such as self-awareness, self-control, empathy and sensitivity to the feelings of others. The notion of emotional intelligence was first defined by Salovey and Mayer (1990), who proposed that it involves the capacity to perceive emotion, integrate emotion in thought, understand emotion and manage emotions effectively."

Emotional intelligence is the ability to identify, use, understand, and manage emotions in positive ways to relieve stress, communicate effectively, empathize with others, overcome challenges and defuse conflict.
