How Often to Keep a Gratitude Journal, and What to Expect

Few wellbeing habits get recommended as often as the gratitude journal. Therapists suggest it, self-help books give it whole chapters, and you can buy notebooks with the prompt already printed at the top of every page. The research behind it is real. It’s also more modest than all that enthusiasm would suggest.

The first experiments, most of them run in the early 2000s, are worth a closer look, because they say as much about how to keep a gratitude journal as about whether it works. One of them found that writing more often didn’t help.

The Studies Everyone Cites

In 2003, Robert Emmons and Michael McCullough asked a group of students to keep a short weekly record for ten weeks. Some wrote down five things they were grateful for. Others listed five hassles from their week. By the end, the gratitude group felt better about their lives as a whole, was more optimistic and reported fewer physical complaints. They also spent about an hour and a half more a week exercising than the hassles group. The exercise figure is striking, but it came from what the students reported themselves, so it’s worth holding loosely.

Two years later, Martin Seligman and colleagues tested several short exercises against each other. In one, people wrote down three things that had gone well each day, and why, for a single week. They were happier and had fewer depressive symptoms for up to six months afterwards. In another, the “gratitude visit”, people wrote a letter of thanks to someone they had never properly thanked and delivered it in person. That gave a big boost, but it didn’t last. The three-good-things effect held up far longer.

Once a Week Might Be Enough

Sonja Lyubomirsky, Kennon Sheldon and David Schkade described a detail in 2005 that most gratitude advice skips over. People who counted their blessings once a week got a lift in wellbeing. People who did it three times a week did not. The authors suspected that doing it so often turned it into routine, one more thing to get through, and it stopped registering. It’s one finding with one proposed explanation, so don’t treat it as a rule.

Still, if you’ve tried a daily list, you may recognize the pattern. By the third week the same handful of items keep coming back and you’re writing on autopilot. Being specific is one way around that. “My sister” is a perfectly good thing to be grateful for, but by week five it’s a reflex. “My sister called on Tuesday just to ask how the interview went” makes you recall the actual moment, which is close to what Seligman’s exercise asked for when it had people write down why something went well.

What to Expect From It

In 2016, Don Davis and colleagues pooled studies of gratitude interventions in a meta-analysis. The effects on wellbeing were positive but small. When gratitude exercises were compared with active control activities, meaning other tasks that asked people to do something rather than nothing, the advantage was small or negligible. That suggests some of the benefit may come from sitting down regularly and paying attention to your week at all.

None of this makes it pointless. A small, cheap lift that you happen to enjoy is worth having, and if the habit doesn’t suit you, the research gives you no reason to feel bad about dropping it. It isn’t a treatment for depression, either. If your mood has been low most days for two weeks or more, talk to your doctor rather than adding a writing habit.

A Version Worth Trying

Start with once a week. Attach it to a time that already exists, like Sunday evening after the dishes, and write down three to five things from the past seven days, each with a line on why it happened or why it mattered to you. Give it ten weeks, the length of the original study, before you decide whether it’s doing anything. If it starts to feel like homework, skip a week and come back to it.

Lamplit’s journal doesn’t have a gratitude prompt. Its three daily prompts ask what you did today to improve on your main issue, what you’ll do tomorrow to build on it, and where you want to be in three to five years. If you want gratitude in there, one specific line inside your “Today’s growth” answer does the job. Or keep the weekly list on paper and use the journal’s mood check-in, which takes three taps. Mood trends show up in the journal’s analytics, so after a couple of months you can look back and see whether anything has shifted since you started.
