Mood Tracking for Depression: The Data That Actually Helps
A person with depression often can't tell whether they're improving because bad days feel bigger than good days in the moment. A structured mood record — a number, once a day, for months — reveals trends the person themselves cannot see. It also helps the treating team make specific medication and therapy adjustments based on data rather than the last week's memory.
What to track daily
- Overall mood (1-10).
- Sleep hours and quality.
- Appetite (normal, reduced, increased).
- Energy (1-10).
- Anhedonia — did anything feel enjoyable today?
- Motivation for basic tasks.
- Any specific event or trigger.
- Medications taken (adherence).
- Any substance use.
The specific reason numbers work
Memory over-weights recent days. A person feeling low today may believe they've been low all month, when a week ago they were better. Numbers on a chart make the actual trajectory visible.
The standard scales for periodic use
- Scale: PHQ-9 · What it measures: Depression severity · Frequency: Every 2-4 weeks
- Scale: GAD-7 · What it measures: Anxiety severity · Frequency: Every 2-4 weeks
- Scale: EPDS · What it measures: Postpartum depression · Frequency: At 4-6 weeks, 3 months postpartum
- Scale: Beck Depression Inventory · What it measures: Depression severity · Frequency: As directed
- Scale: Columbia Suicide Severity Rating · What it measures: Suicidal ideation · Frequency: At crisis points and follow-up
These are freely available. Filling them out every 2 weeks and bringing the scores to your psychiatrist gives them a specific data point to work with instead of a subjective description.
The specific data that guides treatment
- PHQ-9 improving from 15 → 10 → 7 over 8 weeks: current treatment working.
- PHQ-9 stable at 15 despite 6 weeks of treatment: change needed.
- Anxiety scores rising while depression falling: consider treatment mix.
- Sleep trending worse despite mood improving: address sleep specifically.
- Suicidal ideation trending upward: urgent conversation.
What triggers to note
- Specific stressful events (work, relationship, health).
- Sleep disruption.
- Medication changes.
- Physical illness.
- Seasonal changes (winter for some, summer for others).
- Anniversaries of difficult events.
- Social patterns (isolation increasing or improving).
Warning signs to flag immediately
- Sudden mood drop lasting > 3 days.
- New suicidal thoughts or plan.
- Complete loss of interest in previously-enjoyed activities.
- Sleep < 3 hours or > 12 hours.
- Complete inability to perform basic self-care.
- Any self-harm thoughts.
- Increase in substance use.
- Detachment or dissociation.
If any of these appear, contact your treating team the same day. Not the next appointment.
The specific care coordination
- Share the tracker with your psychiatrist at every appointment.
- Share PHQ-9 scores at each medication review.
- Share with therapist to inform session focus.
- Share with GP for coordinated physical health.
- Keep a copy of the tracker outside the health app in case you need urgent access.
The 6-month view
Six months of daily mood scores charted on one page usually shows one of three patterns: steady improvement, wobbly plateau, or drift downward. Each suggests different action. Without the data, the person and clinician often don't know which pattern they're in.
Privacy specifically for mental health data
Mental health data is often more sensitive than physical health data. Store in the most private section of your record. Consider whether family caregivers need visibility — often the person themselves and treating team are enough. A well-designed record app supports this level of granular privacy.
