Mega-study analyzes the impact of gratitude interventions‎

Are some interventions designed to induce gratitude more effectively than others? In which countries and cultures do they work best to improve mood, strengthen bonds between people and promote social reciprocity? A study aimed at answering these questions—conducted in 34 countries with more than 10,000 participants—had its results published in PNAS. In Brazil, the project received the help of researchers and 598 volunteers who responded to intervention prompts via an online tool.
