Is the practice of noting down a few things that you are grateful for each day really help you feel better?
A gratitude journal is a diary of things for which one is grateful. Gratitude journals are used by individuals who wish to focus their attention on the positive things in their lives.
Gratitude, the feeling of appreciation or thanks, has gained a lot of attention in the field of positive psychology. Some studies have found that those who are habitually grateful are happier than those who are not.
One of the (highly cited) studies mentioned there, Emmons and McCullough (2003) claims that "gratitude listing" had benefits in a (causal) experiment:
The effect of a grateful outlook on psychological and physical well-being was examined. In Studies 1 and 2, participants were randomly assigned to 1 of 3 experimental conditions (hassles, gratitude listing, and either neutral life events or social comparison); they then kept weekly (Study 1) or daily (Study 2) records of their moods, coping behaviors, health behaviors, physical symptoms, and overall life appraisals. In a 3rd study, persons with neuromuscular disease were randomly assigned to either the gratitude condition or to a control condition. The gratitude-outlook groups exhibited heightened well-being across several, though not all, of the outcome measures across the 3 studies, relative to the comparison groups. The effect on positive affect appeared to be the most robust finding. Results suggest that a conscious focus on blessings may have emotional and interpersonal benefits.
Has this finding been replicated in other experiments?
