A mood tracker works when each day’s entry records four things: how much your mood interfered with what you had to do, how many hours you slept, one line on what happened, and one word for how irritable you were. The rating is the smallest part. The three fields beside it are what turn a column of numbers into something you can read.
Almost every mood tracker template online asks you to shade a box from one to ten, or pick a colour, and then says nothing at all about what the number means. There is a version that does define it, it is free, and it has been validated in a multi-site research network. Its question is not “how did you feel today”.
The Problem With Rating a Day Out of Ten
This is not an argument about pretty grids. If you want a decorated monthly spread because it is satisfying to fill in, that is a real reason and you should keep doing it. A habit tracker is a grid for behaviour you chose, and it works precisely because “did I do it” has one honest answer.
Mood does not work like that. The trouble with an undefined 1-10 scale is drift. A 6 in March means “a bit flat, got everything done”. By July, after a rough stretch, a 6 has quietly become “functional”. Nothing on the page anchors the number, so the anchor moves with you – and it moves fastest exactly when the mood is changing, which is the only time you needed the record to be stable.
The result is a year of data that cannot be compared with itself. Which defeats the single purpose of tracking.
The Question the Validated Version Asks
The National Institute of Mental Health developed an instrument for this, the prospective Life Chart Method. Denicoff and colleagues published a validation of it in Psychological Medicine (vol. 30, no. 6, November 2000, pp. 1391-7), and the sentence that matters is in the first paragraph of the abstract. The method
allows for the daily assessment of mood and episode severity based on the degree of mood associated functional impairment.
Functional impairment. Not intensity of feeling – interference with functioning. How much did it cost you to do the things the day required?
The instrument’s four levels of low mood are defined in exactly those terms. Born and colleagues set them out in BMC Psychiatry (2014):
Mild: “awareness of depression, but associated with little or no functional incapacity”
Low moderate: “some extra effort being required”
High moderate: “great extra effort required to complete needed tasks”
Severe: “essentially complete incapacitation”
Read those as everyday sentences and you get a usable scale that does not drift:
- 1 – I noticed it and it changed nothing. The day ran normally.
- 2 – Everything took a bit more pushing. I did it all, slower.
- 3 – I had to force the necessary things and dropped the rest.
- 4 – I did not do what the day required.
That is a question you can answer the same way in March and in July, because it is anchored to observable events rather than to a felt sense you are grading against an invisible average.
The instrument has a mirror image above the line as well – four degrees of elevated mood, with a zero point in the middle representing a balanced, well-functioning state, which the literature calls euthymic. The full chart puts elevation above the dateline and low mood below it. I mention the shape because it is genuinely the design, and I am going to leave the upper half alone, for a reason set out further down.
Write It Today
The method is prospective. That word is doing real work: entries are made on the day, every day, rather than reconstructed later. Born and colleagues give the reason plainly – daily rating carries “less risk for recall bias as compared with retrospective self reported data.”
This is the rule most decorated mood trackers break. Filling in a fortnight of squares on a Sunday afternoon produces a beautiful page and a fictional dataset, because what you are actually recording is your current mood’s opinion of the last two weeks.
Put the rating somewhere that already happens at a fixed time. If you keep a five-minute wind-down already at the right time of day, the rating is one extra line in it. Same page, same moment, no new habit to build.
The Four Columns Beside the Mood
Here is the part that no printable-grid page seems to mention. The life chart does not record mood on its own. Alongside the daily rating it captures medications, life events, hours of sleep, and irritability.
That is the difference between a number and a finding. A column of ratings tells you that some days were worse. A column of ratings with hours slept next to it tells you something you can act on by the end of the month.
Four fields, and they take about twenty seconds:
- Hours slept. The single highest-yield companion field. If you already note how the night went for a dream journal, you have this one for free.
- One line on the day. Not a diary entry. “Presentation”, “argument with M.”, “nothing”. Enough that a spike has a caption six weeks later.
- Anything taken. Medication, if you take any, and a note when a dose or a brand changes. Also worth flagging alcohol and how much caffeine, if either is in play.
- Irritability, one word. It moves independently of low mood and it is often the earliest thing that anyone else notices.
Fourteen rows of that is a fortnight, and a fortnight is usually enough to see whether your bad days are following your short nights.
The gap between a template that looks like a system and a template that produces a finding is usually one extra column and a defined scale. Working out which column, for a given technique, means reading the instrument rather than the blog posts about it. That is what I do here, and the newsletter is where it lands first.

A Template You Can Rule in Two Minutes
- Turn a notebook page sideways and rule five columns: date, rating, sleep, day, irritability.
- Write the four rating definitions at the top of the page, in your own words, once. Do not rely on remembering them. The definitions on the page are what stops the drift.
- Fill one row a day, at a fixed moment you already have.
- Rate the interference, not the feeling. The question is: how much did my mood get in the way of what today required?
- Never backfill more than one day. If you miss three, leave them blank. A blank row is data. A guessed row is noise.
- Read it at fourteen rows. Cover the mood column with your hand and look at sleep alone first, then uncover. You are looking for one relationship, not a theory of yourself.
| Date | Interference (1-4) | Slept | The day in four words | Irritable |
|---|---|---|---|---|
Paper works. A spreadsheet works and sorts. An app works if opening it is not the friction that ends the habit – which is the general problem covered in keeping a daily line going.
What This Is and Is Not
The Life Chart Method was built to track the course of bipolar illness and to measure how people respond to treatment. That is the population it was validated in – the 2000 study covered 270 patients across the five sites of the Stanley Foundation Bipolar Network, and it validated the version filled in by clinicians. A later study found that patients’ own daily self-ratings lined up well with the clinician-rated scales, which is the finding that makes a self-kept version worth anything at all.
What this article has taken is three design decisions: define the scale by interference, rate today rather than in retrospect, and record four things beside the mood. It has not handed you a clinical instrument, and it is not asking you to score the upper half of the scale to work out something about yourself. That is what the elevation side is for, in the hands of people qualified to interpret it.
The other distinction worth being precise about: every study cited here validates a way of measuring mood. None of them shows that measuring it makes it better. A mood tracker is an instrument, not a treatment, and any page that implies otherwise is selling something. What the site can say about journaling and wellbeing is set out in what the research does and does not support, and it is careful about exactly this line.
One practical thing a record does do: it makes a ten-minute appointment much better. If what you write down worries you – a run of 3s and 4s, a pattern you cannot explain, sleep falling apart – take the page to a doctor. Six weeks of dated rows is a far better answer to “how have you been?” than anything anyone can reconstruct on the spot.
How Long Before It Tells You Anything
Two weeks gets you the sleep relationship, if there is one, and that is the most actionable thing in the whole exercise.
A season gets you shape – whether the low stretches are three days or three weeks, whether they follow anything, whether they arrive at a time of year. This is worth knowing and it takes an unglamorous amount of time.
Nothing gets you a diagnosis. Not a year, not five. The record is evidence for a conversation, not a conclusion.
If You Want the Real Forms
Bipolar Network News publishes the NIMH Life Charting Method forms free – patient and clinician versions, prospective and retrospective, plus a simpler monthly mood calendar. They are built for people managing a diagnosed mood disorder, and if that is you, use those rather than the five-column page above.
For everyone else, the five columns are the transferable part. The rest of the template library has the daily and weekly formats this sits next to.
The useful move here is not buying a nicer tracker. It is writing four sentences at the top of a page defining what your own numbers mean, and then not letting them drift.
A tracker you have kept for a month and cannot interpret is a common and slightly demoralising place to end up. The fix is almost always in the design rather than the discipline. I send a short email now and then with the version of a technique that came from the source rather than the search results. Subscribe here and the first one arrives within the hour.
