PMDD test — what no questionnaire can tell you
You type "PMDD test" and get a quiz: five questions, score at the end. The problem: PMDD cannot be diagnosed retrospectively. That's built into the DSM-5 definition itself.
Why a short online test isn't enough
PMDD is a mood disorder tied to the luteal phase of the cycle. What matters isn't whether you have specific symptoms — it's when they appear, when they disappear, and how severe they are relative to the rest of the cycle. You cannot extract that from a single questionnaire, because memory selectively keeps hard days and drops the good ones.
Screening tools like PSST (Premenstrual Symptoms Screening Tool) are useful as a first filter — they tell you whether tracking is worth starting — but they don't diagnose. The clinical literature treats them that way too.
The only reliable test: two cycles of prospective tracking
ISPMD (International Society for Premenstrual Disorders) and DSM-5 agree: a diagnosis requires daily symptom tracking across at least two full cycles. Prospectively — each day, in real time, not from memory after the fact.
What to track each day
- Overall mood (e.g. 1–5).
- Irritability / anger.
- Anxiety / tension.
- Energy / fatigue.
- Concentration.
- Sleep (duration, quality).
- Physical symptoms (breast tenderness, bloating, pain).
- Functional impact (did you cancel something? was there a conflict?).
- Cycle day (or at least: first day of period).
The clinical standard is the DRSP (Daily Record of Severity of Problems) — 21 items, every day. It's a lot. Most people don't last on paper and quit after a week. An app that captures these in 30 seconds a day raises the odds the tracking actually survives two full cycles.
What two cycles of data show
After two cycles you can see whether symptoms genuinely cluster in the week before menstruation and resolve within a few days of bleeding starting. That symptom-free window after the period is what separates PMDD from recurrent depression or an anxiety disorder — both of which don't fade in any cycle phase.
If symptoms also persist in the follicular phase (post-period), the criteria for PMDD are not met — but that doesn't mean they don't deserve attention. It can indicate a separate mood disorder that worsens in the luteal phase (premenstrual exacerbation, PME).
What to bring to the appointment
A sheet / printout / PDF export of two cycles of tracking. Concrete data shortens a 40-minute speculative visit into a 10-minute decision. A clinician familiar with PMDD (often a gynaecologist-endocrinologist or psychiatrist) is looking precisely for that cyclical pattern — without data they have to ask you to start tracking and come back in two months.
What comes after
If criteria are met, PMDD is treated, not just "managed". The strongest evidence is for SSRIs (often dosed only in the luteal phase, with effect in days rather than weeks) and continuous combined hormonal contraception with drospirenone. These are decisions made with a clinician, not an app. The app supplies the data for that decision.
