Gratitude has been linked to enhanced subjective well-being and life satisfaction in previous research studies. Gratitude has also been identified as one of the positive emotions that has played an important role as a coping mechanism for survivors in the aftermath of catastrophes and tragedies. The impact of gratefulness, which is closely linked to gratitude but highly distinct from it, is less researched. A total of 52 participants took part in this quantitative between-subjects experiment with repeated measures, testing the causal effect of a daily gratefulness practice on coping, subjective well-being, subjective life satisfaction and gratefulness during the 2020 Covid-19 pandemic. Contrary to much of the published research on gratitude and gratefulness this study could not support the previous research. No statistically significant results were found from the daily gratefulness manipulation when comparing the control and experiment groups.
