A personal mood score and a mental health screening questionnaire can both produce numbers, but they may describe different things. Before comparing results, check the tool's name, the question it asks, the period it covers and what its scoring instructions mean. A daily rating cannot be converted into a screening result just because both use a numbered scale.
This guide explains the distinction and offers a simple way to label records before an appointment. It does not interpret an individual's screening result or provide a diagnosis.
A personal mood rating describes the question you chose
In a private diary, you might rate how your evening felt from 1 to 5, with higher numbers meaning a more positive mood. Another person might use words, describe the whole day or record several feelings separately. Those choices change what the record represents.
A number has little context without its question and labels. A 4 out of 5 for a pleasant evening is not a statement about every symptom you experienced over the past fortnight. It also does not establish why that evening felt different. Our mood trends guide shows how the timeframe and available entries affect what you can reasonably say about a record.
Personal notes may still help you describe an experience. They do not become a clinically validated measure simply because you record them regularly, draw a chart or average them.
A screening questionnaire has its own questions and instructions
A named questionnaire is more specific than a general request to rate your mood. Its wording, response choices, timeframe and scoring belong to that instrument. Evidence about one questionnaire cannot automatically be applied to a different set of questions or an app's combined score.
For example, the PHQ-9 asks about the frequency of nine depression symptoms over the previous two weeks. A 2021 systematic review and individual participant data meta-analysis compared its screening results with diagnostic interviews in adults. The analysis focused on adult screening samples rather than people recruited from psychiatric or youth settings or specifically because of identified depression symptoms. It examined how accurately the questionnaire identified people who did or did not meet interview criteria, including false positive and false negative results.
That evidence concerns the PHQ-9 in the populations and settings studied. It does not validate a personal diary scale or PsychPod. It also does not mean every questionnaire labelled a "mental health test" has comparable evidence.
If a clinician asks you to complete a particular form, use the version and instructions they provide. If a question is unclear or you cannot answer it, ask how to proceed rather than replacing it with your diary question. Keep unanswered items visible and let the responsible clinician or service advise how the result should be handled.
Screening contributes to assessment
A screening result can indicate that further assessment is appropriate. It is not, by itself, a complete account of a person's mental health. A result below a screening threshold does not rule out every difficulty, and a result above it does not by itself establish a diagnosis.
NICE's depression guidance recommends considering a validated measure when assessing suspected depression. It also calls for a comprehensive assessment that goes beyond counting symptoms, considering their severity, history, duration, course and effect on functioning.
This explains why an appointment may include questions about everyday life, earlier experiences and changes over time alongside a form. A conversation is not made unnecessary by a reassuring app score. If you have concerns, describe them even when a number seems inconsistent with how you have been managing.
A fictional example: two records that answer different questions
Imagine someone gives their evening a 4 out of 5 after a welcome conversation with a friend. At an appointment the next morning, they are asked to complete a PHQ-9 about the previous two weeks. They have also been finding it difficult to concentrate and complete usual tasks during that period.
The positive evening entry does not cancel those difficulties. Nor should it be used to fill in the questionnaire. The person could bring this short explanation:
Personal diary:
4 out of 5 for how my evening felt yesterday.
On my own scale, higher means a more positive mood.
Questionnaire:
PHQ-9 completed at today's appointment.
I followed its instructions about the previous two weeks.
The completed form is separate from my diary rating.
What I want to discuss:
Yesterday evening felt better, but concentration and usual tasks
have been difficult over the past two weeks.The example is invented. It does not supply a PHQ-9 score, imply a diagnosis or demonstrate that social contact caused an improvement. It shows how a person can keep the two records distinct while describing both experiences honestly.
A label card for any result you bring
Before comparing or sharing a number, keep its original context with it. You can use this editorial card with a personal record or a completed questionnaire:
Tool or questionnaire name, version and language if known:
Date completed:
Question or area being recorded:
Time period the instructions asked about:
Original result exactly as provided:
Any unanswered items or instructions I found unclear:
What the tool's own scoring explanation says:
What I would like to ask at the appointment:If you do not know something, write "not sure" and bring the original form or explanation. The card is not a scoring algorithm, a validated assessment or a request to share more personal information than you intend. It is a way to avoid presenting a number without knowing where it came from.
Do not add together results from different tools, invent a conversion between their scales or apply one questionnaire's cut-off to an unrelated score. Even two results displayed from 0 to 100 may have different definitions and directions. Ask the clinician or service which records they want to discuss. Our GP mood appointment guide helps organise the duration of difficulties, their effect on daily life and your questions.
Where PsychPod fits
PsychPod's methodology describes a combined index of self-reported wellbeing areas. Its 0 to 100 values are index scores, not probabilities of illness or future actions. Higher means an area felt more supported in that check-in; the combined score is not clinically validated.
PsychPod is for reflection. It does not diagnose, treat, establish causes, predict behaviour or crises, or monitor your safety. Its score should not be treated as a substitute for a questionnaire your clinician requested or for an assessment of a concern.
You do not need a score before asking for help
NIMH guidance recommends discussing mental health concerns with a primary care provider. It advises professional help for severe or distressing symptoms lasting two weeks or more.
You can ask for help sooner if the severity or effect on everyday life warrants it. You do not need to wait for a questionnaire, collect a complete diary or reach an app threshold before asking for help.
If you cannot stay safe, contact local emergency services now. A score or chart cannot tell you whether it is safe to wait.
