Objective: To provide normative data on the Kessler Psychological Distress Scale (K10), a scale that is being increasingly used for clinical and epidemiological purposes.
Method: The National Survey of Mental Health And Well-Being was used to provide normative comparative data on symptoms, disability, service utilisation and diagnosis for the range of possible K10 scores.
Results: The K10 is related in predictable ways to these other measures.
Implications: The K10 is suitable to assess morbidity in the population, and may be appropriate for use in clinical practice.
