Journal prompts for mental health

How you are today

Putting a feeling into words is at the heart of the writing studies, a line of research started by the psychologist James Pennebaker. In the first of those studies, college students wrote about their deepest thoughts and feelings for 15 minutes on 4 days in a row (Pennebaker and Beall, 1986). Over the next 6 months, they made fewer visits to the student health center than students who wrote about everyday topics.

A later analysis that pooled many of these writing studies found that people reported better physical health and well-being after writing (Smyth, 1998). The number out of ten in the first prompt gives a feeling a shape you can compare across days.

Sleep, movement and daylight

Sleep, movement and daylight are basics that public health bodies name. The CDC, the US public health agency, says adults aged 18 to 60 need 7 or more hours of sleep (the CDC). The National Institute of Mental Health (NIMH), in its advice on caring for your mental health, says “just 30 minutes of walking every day can boost your mood” (NIMH).

A survey of 19,806 people in England looked at time in nature. People who spent at least 120 minutes a week there were more likely to report good health and well-being (White and colleagues, 2019). The link peaked between 200 and 300 minutes. The survey found a link, not proof of cause, so treat the number as a nudge, not a target.

People

Time with people is on NIMH’s list too: reach out “to friends or family members who can provide emotional support and practical help” (NIMH). The prompts ask for minutes, because a week can feel full of people while holding very little time with any of them.

What fills your days

The shape of the day matters too, not only its mood. These prompts look at where the hours went without grading them. A day that went to things that gave nothing back is worth noticing, gently. The answer is often one small change, written down with a time.

Reading back two weeks

Two weeks is the line NIMH uses for when to get help. It advises professional help for severe or distressing symptoms that last 2 weeks or more, such as trouble sleeping, changes in appetite, trouble concentrating or loss of interest (NIMH). A written record makes that easier to see, and easier to describe, than memory alone.

Journaling helps some people a little, and the studies say so plainly. Here is what they measured.

• 20randomized trials pooled. Scores on mental health measures fell 5% more with journaling than without.Sohal and colleagues, 2022
• 146randomized studies of expressive writing. The average effect was positive but small.Frattaroli, 2006
• 120minutes a week in nature, the point where reported health and well-being rose.White and colleagues, 2019
• 2weeks of hard days: the point where NIMH says to get professional help.NIMH

The review behind the first number pooled trials of journaling for PTSD (post-traumatic stress disorder), anxiety and depression. Its authors say the studies were very mixed and had flaws, so the size of the benefit is uncertain (Sohal and colleagues, 2022). They suggest journaling as an add-on to care, not a replacement.

The researchers who started the field are just as plain. Expressive writing, the method from those first studies, “is not a panacea”: it does not fix everything, and its overall effect is modest (Pennebaker and Chung, 2011).

The myth: “If writing made you feel worse, it isn’t working.”

Many prompt lists promise that journaling will make you feel better. The studies found the opposite in the short term. Writing about something hard often raised distress right after the session, and that rise was unrelated to the later outcomes (Smyth, 1998).

One review advises writing for no more than 20 minutes at a time, and stopping whenever you want to (Baikie and Wilhelm, 2005). If a prompt gets too heavy, stop, or pick a lighter one.

A good place for these prompts keeps the feeling and the facts together, and counts the hours from what you already write or say, with no timers or forms. Most journaling apps keep how the day felt and lose where it went, so the sleep and the hours with people stay a guess.

One app built for this is Think in Numbers, a smart journaling app with time tracking built in.

You write or say your day in your own words, as it happens or all at once. The app reads what you wrote and counts the hours that went to each part of it: sleep, movement, time with people, your phone, and the time you never mentioned (shown as unaccounted). Then it shows those hours over days and weeks. It has a mood and energy check-in. You can make a journal with your own prompts, such as the ones on this page, and journal history shows each day’s reflection beside its hours.

If the read-back shows something hard on most days for two weeks or more, that is the point NIMH names for getting help. If you see a doctor, bring the entries with you. They describe the weeks better than “it’s been bad”.

Help is a call or a text away. A doctor, therapist or counselor can help with what these prompts only bring to the surface. A primary care provider, such as your regular doctor, can do a first screening and refer you on (NIMH).

Journaling is a small, real help. Pair a feeling with a few facts, read back every two weeks, and get help when the weeks stay hard. More sets: anxiety prompts, healing prompts and evening prompts.
