The K10 Test Explained: Measuring Psychological Distress
The K10 test is a short, widely used questionnaire that measures psychological distress. It is made up of ten questions about how you have been feeling over the past four weeks, covering things like nervousness, tiredness, hopelessness, and restlessness. It is one of the most common screening tools used in Australian general practice and mental health care.
The K10 does not diagnose any condition. It gives a snapshot of distress at a point in time, which helps a clinician understand how you are coping and whether further support might help.

Each of the ten questions is answered on a five point scale, from none of the time to all of the time. The answers add up to a total score, usually between 10 and 50. A higher score suggests a higher level of distress. Beyond Blue offers the K10 and explains the broad bands that scores fall into, from low distress to very high distress.
The bands are a guide, not a label. Your clinician reads the score alongside what is happening in your life rather than treating the number on its own.
The K10 helps a clinician open a conversation, gauge severity, and track change over time. Because it is quick and consistent, the same person can complete it again later to see whether things are improving. It is often part of preparing a Mental Health Care Plan, the referral pathway that can connect you with a bulk billed psychologist and the right level of support.
At Abby, this fits the principle of understanding. When the clinician who reviews your K10 also holds your history, the result is read in context rather than in isolation.
Broadly, lower scores suggest you are likely to be feeling well, while higher scores suggest higher distress that may benefit from support. The exact cut offs vary slightly between guidelines, which is why interpretation belongs with a clinician rather than a self read total. A high score is not a diagnosis; it is a signal to talk further.
Equally, a low score does not always mean everything is fine. If you are worried about how you feel, that is reason enough to reach out, whatever the number says.
It is important to be clear that the K10 measures distress, not a specific illness. It cannot tell you whether you have depression, anxiety, or any other condition. A clinician uses it as one piece of a wider assessment that includes your history, your circumstances, and a conversation. Healthdirect explains that diagnosis always involves a proper clinical assessment.
Start a conversation with a clinician who understands.
Abby uses the K10 as part of understanding how you are feeling before and during care. Completing it helps your clinician start informed, so you spend less of your appointment explaining and more of it being heard. It also gives a baseline to measure progress against if you return. You can read about what Medicare covers in our guide to Medicare and mental health.
Whatever your score, the next step is a conversation. An Abby GP can talk through how you have been feeling, prepare a Mental Health Care Plan where appropriate, and connect you with further support.
