Kessler Psychological Distress Scale (K6) Test

For people who want a structured way to consider difficult emotional experiences, the Kessler Psychological Distress Scale (K6) Test provides a focused starting point. This psychological distress test helps respondents examine patterns associated with non-specific distress and decide what questions about their wellbeing may deserve closer attention. It is suited to anyone who wants an organized perspective on the experiences addressed by the questionnaire.

What This Assessment Explores

Non-specific psychological distress is the focus: difficult emotional experiences that do not identify one disorder.

Six questions address nervousness, hopelessness, restlessness, effort, sadness, and worthlessness. Together, the K6 questionnaire's items contribute to one overall distress result, not separate diagnoses.

The item themes show how the result relates to these experiences:

• Emotional tension reflects nervousness or fidgety restlessness.
• Hopelessness captures discouragement and difficulty imagining positive change.
• Effort and energy indicate whether ordinary activities feel unusually hard to manage.
• Mood and self-worth reflect sadness and feelings of worthlessness.

Psychological Distress Scale ranges from 6-30 and assesses distress during the past 30 days. Displayed bands are Low distress (6-12), Moderate distress (13-24), and High distress (25-30). Higher scores indicate more severe distress and possible mental health problems; lower scores indicate little or no distress. The result describes intensity, not cause.

Methodology and Evidence Base

Each item uses an ordered frequency response, moving from the least frequent experience to the most frequent. Answer choices use categories such as “None of the time” to “All of the time” or “Never” to “Always.” The questionnaire produces the displayed result, but its scoring is presented without an answer-by-answer aggregation or point-assignment rule.

The questionnaire is an online version using K6 content, whereas the cited studies concern the published K6 instrument. Kessler and colleagues introduced K6 in 2002 as a brief measure of non-specific psychological distress. Relevant K6 screening research includes Furukawa's 2003 examination of K6 alongside K10 in Australian survey data, and a 2010 study by Kessler and colleagues evaluated its screening performance across the WHO World Mental Health survey initiative. Those findings support the relevance of the source instrument, but they do not directly validate every feature of this online scoring format.

Because responses are self-reported, current circumstances, recall, self-awareness, and willingness to disclose can influence the result; it indicates reported distress but cannot establish its cause.
