From the pages of the Wall Street Journal:
In an upcoming paper in the Journal of Happiness Studies, Dr. Froh and colleagues surveyed 1,035 high-school students and found that the most grateful had more friends and higher GPAs, while the most materialistic had lower grades, higher levels of envy and less satisfaction with life. “One of the best cures for materialism is to make somebody grateful for what they have,” says Dr. Froh.
Much of the research on gratitude has looked at associations, not cause-and-effect relationships; it’s possible that people who are happy, healthy and successful simply have more to be grateful for. But in a landmark study in the Journal of Personality and Social Psychology in 2003, Dr. Emmons and University of Miami psychologist Michael McCullough showed that counting blessings can actually make people feel better.
