Two-question test

from Wikipedia, the free encyclopedia

The two-question test is according to S3 guideline for screening for unipolar depression recommended. Since the test only consists of two questions, it is a very time-efficient method, through which depressed and non-depressed people are recorded with a very good probability. The guideline quotes a study according to which depressed and non-depressed people can be distinguished by just two questions with the following probabilities:

  • Sensitivity : The test correctly detects people who are depressed with a probability of 96%.
  • Specificity : 57% of non-depressed people would also recognize that they are not depressed.

The two questions that must be asked are literal:

  • 1. "In the past month, have you often felt down, sad, depressed, or hopeless?"
  • 2. "In the last month, have you had significantly less pleasure and pleasure in things that you otherwise enjoy doing?"

If both questions are answered with “yes”, the formal diagnostic criteria should be recorded, because the diagnosis of depression according to ICD-10 can only be made by explicitly collecting all relevant main and secondary symptoms. Looking at the two questions, only two main criteria are captured here.
