How is PMDD diagnosed? The DRSP explained

Why is there no blood test for PMDD?

Hormone levels are usually normal in people with PMDD. The difference lies in the brain’s sensitivity to normal hormonal fluctuations, which one blood sample cannot measure. Blood tests can still help rule out other causes, such as thyroid disorders.

What is the DRSP?

DRSP means Daily Record of Severity of Problems. Developed for clinical research and used internationally, it aligns with DSM-5 criteria. You rate 21 symptoms every day from 1, not at all, to 6, extreme, plus three yes/no interference items covering work or education, relationships and activities. See all 21 symptoms.

The 21 DRSP symptoms

The scale is 1 not at all, 2 minimal, 3 mild, 4 moderate, 5 severe and 6 extreme.

Emotional

• Mood swings
• Irritability or anger
• Depressed mood
• Hopelessness
• Worthlessness or guilt
• Anxiety or tension
• Sensitivity to rejection

Cognitive and behavioural

• Reduced interest
• Difficulty concentrating
• Fatigue
• Feeling overwhelmed or unable to cope
• Feeling out of control
• Conflict with others

Physical

• Increased appetite or overeating
• Food cravings
• Hypersomnia
• Insomnia
• Breast tenderness or swelling
• Bloating or weight gain
• Headache
• Joint or muscle pain

The three interference items measure reduced productivity, interference with hobbies or social activities, and interference with relationships.

How does the diagnostic process work?

1. Rate all 21 symptoms every day, ideally at a regular time. This takes around two minutes.
2. Complete at least two full cycles to establish whether the pattern repeats.
3. Compare phases: symptoms should be clearly higher in the luteal phase and minimal or absent in the follicular phase.
4. View the cyclic overview: based on the C-PASS method, it makes patterns visible without diagnosing.
5. Discuss the results with a clinician, using your ratings or PDF report.
6. Consider other diagnoses, including thyroid disease, bipolar disorder, depression, anxiety and physical causes.

Which clinician should you see?

A GP or primary-care clinician is usually the first point of contact and may refer you to a gynaecologist or psychiatrist. Say clearly that you suspect PMDD and bring your prospective ratings. A psychologist may also support treatment.

PMDD Tracker: the DRSP on your phone

PMDD Tracker digitises the DRSP and identifies menstrual, follicular, ovulatory and luteal phases. Per finished cycle it creates the cyclic overview, and you can export symptom data, heatmaps and phase comparisons as a PDF for your clinician. The app makes patterns visible but does not diagnose, analyse your health or replace clinical assessment.

Without a current menstrual cycle, you can still record symptoms by calendar date and share them. The cyclic overview needs a finished cycle with enough filled days before and after menstruation, and will not work without cycle data. See tracking without a cycle and PMDD and perimenopause.
