CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

Any questions left?

What does this questionnaire measure?

It measures general psychological distress, including symptoms often linked with stress, anxiety, and depression. It reflects overall emotional strain rather than a specific disorder.

What time period should responses cover?

Responses should reflect how often each feeling occurred during the past four weeks. Select the option that best represents the typical frequency in that period.

How long does it take to complete?

Most respondents complete it in about two minutes. Completion time may vary based on reading speed.

How are items answered and scored?

Each item uses a frequency scale from “none of the time” to “all of the time.” Higher total scores indicate higher overall distress.

Do results provide a diagnosis or replace a clinical evaluation?

No, results indicate the level of nonspecific distress and are used for screening or monitoring change. Follow-up assessment may be needed when scores are elevated or concerns are present.

WHAT THE TEST MEASURES

About This Assessment

Kessler Psychological Distress Scale (K10) Test

stress level

This brief self-report measure screens for nonspecific psychological distress over the past 4 weeks. The Kessler Psychological Distress Scale (K10) asks respondents to rate how often they experienced common symptoms such as nervousness, hopelessness, or restlessness.

The instrument includes 10 items and typically takes about 2 minutes to complete. It is commonly used to support initial screening and to monitor change in overall distress over time, without making a specific psychiatric diagnosis.

Developed by Kessler, R., the Kessler Psychological Distress Scale (K10) is intended to help identify individuals who may benefit from further clinical assessment or supportive intervention.
