Mental health tests can help you describe distress when it is hard to know where to begin. The K10 offers a general check-in, while the DASS-21 separates depression, anxiety, and stress symptoms. Other questionnaires focus on low mood, elevated mood, changes around your period, pregnancy, or the seasons. This collection also includes distinct screeners for concerning changes in perception and suspicious thoughts, which are not simply mood symptoms.
Choose the questionnaire closest to what you have noticed, rather than taking every test to search for an explanation. A broad screen can organize your concerns; a more specific tool can help you describe a particular pattern. These results are educational screening information, not a diagnosis or a decision about whether you deserve support. If changes are affecting your daily life, you can seek professional help regardless of the score.

|---|---|---|
| You want a broad check of current distress | Mental Health Assessment | The K10 is a starting point, not a screen for every mental health condition. |
| You want separate depression, anxiety and stress scores | DASS-21 Depression, Anxiety & Stress Test | The DASS-21 explores three symptom areas in one questionnaire. |
| You want to understand persistent low mood | Depression Test | The PHQ-9 focuses on depressive symptoms rather than all possible mood changes. |
| You have noticed periods of unusually elevated mood | Bipolar Test | The MDQ considers symptom patterns and their context, not only a total count. |
| You are concerned about changes in perception | Psychosis & Schizophrenia Screening | This PQ-B-informed screening cannot establish psychosis or schizophrenia. |
Mental health and mood tests FAQ
How do the K10, DASS-21 and PHQ-9 differ?
The K10 asks about general psychological distress. The DASS-21 separates depression, anxiety, and stress symptoms into three areas. The PHQ-9 focuses on depressive symptoms. Choose based on the question you want to explore, and do not compare their totals as though they measured the same thing on the same scale.
Does a positive MDQ screen mean I have bipolar disorder?
No. The MDQ is a screening tool, and a positive screen is a reason to discuss your history with a qualified professional. The combination, timing, and impact of experiences matter. A score alone cannot distinguish every possible explanation, and a negative screen does not settle ongoing concerns either.
Why are psychosis and paranoia screeners in this collection?
They offer a clear route for people concerned about changes in perception or suspicious thoughts, alongside broader mental health questions. They are separate from the mood questionnaires because these experiences are not automatically mood symptoms. If changes are new, persistent, or worsening, seek prompt professional assessment rather than relying on repeated online screening.
What if I need help before taking a test?
You do not need a score to ask for help. If you are in immediate danger or facing a medical emergency, contact local emergency services. In the US, call or text 988 for suicidal thoughts or emotional crisis. For ongoing concerns, a qualified health professional can help you decide what comes next.
