Studies in positive psychology, including happiness, well-being, and life satisfaction, are reviewed. The preponderance of the research literature on the promotion of positive psychology tends to focus on broad social competences. However, there is an emerging body of evidence that supports employing specific techniques that are more amenable to school-based practice, can also promote happiness and life satisfaction in children and adolescents. An exploratory study conducted by McCabe-Fitch (2009) is included that exemplified the use of the specific techniques of the Gratitude Letter and Three Good Things in Life.
