Gratitude CHALLENGE

Write down at least 3 things you’re grateful for each day in December.

Study RESULTS

The study involved participants engaging in Gratitude Journal Challenge for 30 days. Data was self-reported, using a Likert scale from 1 (strongly disagree) to 7 (strongly agree) across various health and psychological metrics. The analysis includes both quantitative data and qualitative based on responses from 375 participants. Since the goal of the study is to measure the impact of doing a certain activity for a month quantitative data is presented for participants with high adherence rates (90%+ challenge completion).

Qualitative Findings

Beneficial Aspects Analysis (n=282 responses, 71.0% response rate)

Thematic Distribution:

- Gratitude and Appreciation (34.0%): Enhanced awareness of blessings and thankfulness

- Positive Reframing (24.1%): Shift toward optimistic perspective and focusing on positives

- Mindfulness/Awareness (18.8%): Increased present-moment awareness and attention to daily experiences

- Reflection Practice (18.1%): Structured daily review and evaluation

- Routine Development (17.0%): Integration into daily habits and consistency benefits

- Emotional Regulation (14.5%): Improved mood, reduced anxiety, enhanced emotional balance

Key Insights from Detailed Responses:

Participants reported transformative shifts in cognitive processing:

- "Seeing that my gratitude changed from being grateful for good things happening to me to just anything (people who built roads, the medical system, nature's beauty)" - illustrating expansion of gratitude scope

- "Writing them with more detail felt good. Otherwise you stay more on the surface, now it was more 'deep'" - highlighting the importance of specificity in the protocol

- "Actively looking for the positives in life, even on a grey, wet and cold December day" - demonstrating resilience and cognitive reframing

Extraordinary Experiences (n=185 responses, 46.6% response rate)

While 57.3% reported no extraordinary experiences, meaningful insights emerged from remaining participants:

Transformative Discoveries:

- Recognition of abundance: "Only that I have a lot to be grateful for that I wasn't appreciating!"

- Perceptual awakening: "Just how much wonder there is in the world that we have become immune to"

- Embodied experience: "In my heart, gratitude felt warm and spacious"

- Behavioral change: "It made me look for good things throughout the day...I also no longer had anxiety dreams"

- Perspective Shifts (6.5%): Participants described fundamental changes in worldview and approach to daily life, with gratitude becoming an active lens for experience rather than passive reflection.

Clinical and Practical Implications

Mechanisms of Action

The high correlations within the mental health cluster (r = 0.65-0.87) suggest gratitude practice operates through interconnected psychological pathways:

- Cognitive Reappraisal: Active identification of positives restructures attention and memory

- Emotional Regulation: Regular positive focus dampens stress responses

- Mindful Awareness: Daily reflection enhances present-moment attention

- Social Connection: Gratitude for others strengthens relational bonds

Implementation Recommendations

Critical Success Factors:

- Handwritten format appears essential for engagement

- Specificity requirement prevents superficial practice

- 5-10 minute duration optimizes benefit-burden ratio

- Evening practice may enhance sleep benefits

Population Considerations:

- High acceptability in middle-aged and older adults

- Gender imbalance suggests need for male-targeted adaptations

- Low difficulty ratings indicate broad accessibility

Sustainability Indicators:

- Enjoyment as primary predictor (r = 0.595) of continuation

- Low perceived difficulty crucial for long-term adoption

- Community support mentioned as beneficial factor

Study Limitations

- Self-selection bias: Participants choosing gratitude challenge likely predisposed to benefit

- Self-report measures: Subject to social desirability and recall biases

- Short-term follow-up: Long-term sustainability unknown

Summary and Conclusions

The December Gratitude Challenge demonstrates remarkable efficacy as a low-burden, high-impact psychological intervention. The practice shows particular promise for enhancing emotional well-being, with effect sizes in the mood-calm-stress triad suggesting clinical relevance. The high enjoyment ratings and intention to continue indicate gratitude journaling overcomes typical adherence barriers plaguing behavioral interventions.

The qualitative findings reveal gratitude practice as more than symptom management—participants describe fundamental shifts in attention, perception, and meaning-making. The transition from gratitude for personal benefits to appreciation of systemic and environmental factors suggests the practice cultivates an expanded awareness that may underlie its broad psychological benefits.

Future research should employ randomized controlled designs, examine long-term maintenance, explore mechanisms through neurobiological assessment, and investigate adaptations for broader demographic inclusion. The current findings strongly support gratitude journaling as an accessible, enjoyable, and effective tool for psychological well-being enhancement, particularly suited for integration into preventive mental health initiatives and positive psychology interventions.

Frequently asked questions

How do I join a Challenge?
Currently since 1st of Jan 2026 new Challenges are put on pause as TheChallenge.Org transitions into a non-profit organisation focused on sharing the scientific results learned from the 12 Challenges of 2025. You are however free to browse the previous Challenges in the Challenges tab in the menu and try them at any point and according to your liking.
Where are the instructions for a Challenge?
All necessary instructions are always found on the page of a particular challenge. Just however over the "Challenges" item in the top navigation bar and choose the Challenge you are looking the instructions for. If you haven't received the email 1 day prior to the Challenge don't worry! The email only contains a part of the message which is included on the Challenge page anyway. But the instructions are really extremely simple. For the "10.000 Steps Challenge" it could be "Just walk at least 10000 steps per day". For the "Meditation Challenge" it would be "Just sit and meditate for 15 minutes a day, anywhere, at any time, with any meditation method you can find online".
Where are the Challenges happening?
All Challenges can be done from your location. Each Challenge is done in such a way that there is no particular location to attend to.
At what time during the day do I have to do a Challenge?
Challenges can be done at any time during the day, whether it's morning, evening, or mid day. Though it is much easier to stick to a routine in the morning as mornings can be typically controlled whereas the evening tends to be more chaotic and have unscheduled tasks that need attending.
Is this FREE?
Yes, all challenges are and always will be free to join and participate in.
Why trust us?
We’re not selling anything. We’re learning alongside you
I don't have an Instagram or YouTube account, can I still participate?
Absolutely! You don't need to do anything to participate since the challenges can be done from anywhere. To sign up and receive updates about the challenge or to be able to contribute to a science questionnaire at the end you just need to have an email and join a Challenge on the website.
Is this a non-profit organization?
TheChallenge.Org is a for-knowledge organisation. The organisation is not a typical non-profit. It will have an optional donation model for people wanting to support it and help cover the cost of operations.
Who are the people behind this project?
Karol Banaszkiewicz, our founder, is a seasoned technologist and lifelong health-hacker who noticed a glaring gap in how we track the real effects of daily routines. Driven by a passion for data-backed self-improvement, he committed his own time and resources to launching TheChallenge.Org—to rigorously measure how habits shape our physical and mental well-being.
