A large international study found that brief gratitude practices reliably improved mood among participants in 34 countries, while broader benefits such as life satisfaction and optimism varied by culture and exercise type.

A sweeping international study involving nearly 11,000 people across 34 countries has found that simple gratitude exercises can produce measurable improvements in mood, offering one of the strongest assessments to date of how thankfulness-based practices affect emotional well-being.
The research examined whether gratitude exercises—such as writing letters of thanks, identifying blessings or reflecting on appreciative moments—produce similar effects across different cultural settings. The findings showed that the practices consistently increased positive affect, or improved mood, regardless of where participants lived.
Researchers tested six short gratitude-based activities among 10,696 participants, making the project one of the largest and most geographically diverse experiments ever conducted on the subject. Participants were randomly assigned to complete either a gratitude exercise or one of three neutral control tasks. Afterward, researchers measured immediate changes in several areas of well-being, including positive affect, negative affect, optimism, life satisfaction, envy and feelings of indebtedness.
The study was designed to address a major limitation in earlier gratitude research, which has often relied on smaller groups of participants, brief study periods and samples drawn largely from Western countries. By including participants from nations including Japan, Brazil, Kenya and Germany, the project gave researchers a broader look at whether gratitude practices operate the same way across languages, customs and social norms.
The clearest result was that gratitude exercises improved mood. Across all 34 countries and all six interventions, positive affect was the most dependable outcome. Participants who completed gratitude activities generally reported feeling better afterward than those assigned to neutral tasks.
Other benefits were less uniform. Improvements in life satisfaction, optimism and reductions in negative emotions appeared in some countries and under some intervention formats, but were weaker or absent in others. Researchers also found that the type of gratitude exercise mattered, with certain approaches producing stronger results for particular outcomes.
The findings suggest that gratitude practices may be most useful as a short-term emotional reset rather than a guaranteed way to transform every measure of well-being. While the study supports the use of gratitude as a practical tool for improving mood, it also indicates that culture, individual differences and the specific exercise chosen can shape the broader effects.
The results build on earlier smaller studies published in journals including the Journal of Personality and Social Psychology and the Journal of Positive Psychology, which found that gratitude journals and gratitude letters were associated with increased happiness and lower depression for periods lasting up to six months. The new megastudy adds wider international evidence while also showing that not every claimed benefit appears consistently across populations.
For people who already keep a gratitude journal, write notes of appreciation or pause to count blessings, the study offers scientific support for the mood-lifting effect many report experiencing. For those hoping gratitude alone will sharply improve life satisfaction, reduce anxiety or change broader emotional patterns, the findings suggest expectations should be more measured.
The practical takeaway is that gratitude remains a simple, accessible habit with a reliable emotional benefit. A brief daily or weekly practice—whether listing three good things, writing a thank-you letter or reflecting on a meaningful moment—may help improve mood, though the extent of additional benefits may depend on personal and cultural context.
According to BrightU.AI’s Enoch, the research is consistent with empirical evidence showing that gratitude reliably improves mood across cultures, while other possible effects, including health or relationship changes, may be shaped by cultural differences and may not appear as consistently.
