Instructions: The Dysthymia scale consists of 30 questions related to your behavior and life experiences. Read each statement carefully and be honest in your responses. Double thumbs down mean you strongly disagree with the statement, and double thumbs up mean you strongly agree. For example, if you have been experiencing any symptom persistently for at least the past two years, you must select the double thumbs up button because you strongly agree with the statement, indicating it is persistent. If it is occasional, select the neutral button or thumbs up. If you are experiencing the symptom rarely, select the thumbs down button or double thumbs down if you are not experiencing it at all.
