WHAT THE TEST MEASURES

About This Assessment

Kessler Psychological Distress Scale (K6) Test

stress level

Psychological distress can be difficult to identify early, but it is important to assess efficiently to determine whether further evaluation may be indicated. The Kessler Psychological Distress Scale (K6) is a brief self-report screening measure of nonspecific psychological distress over the past 4 weeks.

The instrument consists of 6 items and typically takes about 2 minutes to complete. Respondents rate how often they experienced common distress-related symptoms (e.g., depressed mood, nervousness), providing an overall index of recent emotional strain.

The Kessler Psychological Distress Scale (K6) is commonly used in clinical and research settings to support initial triage and population screening; it does not establish a diagnosis but can help identify individuals who may benefit from additional assessment. The measure is attributed to Kessler, R.
