This article evaluates the efficacy of a training program focused on increasing emotional intelligence (EI), which was developed for Italian high school students. The training was constructed using an ability-based model of EI. It was hypothesized that specific training would increase both ability and self-reported EI and reduce levels of indecisiveness and career decision difficulties. This article outlines relevant literature and provides a description of the intervention, an evaluation of its efficacy, and a presentation of the results with regard to decisional problems.
