Subjects and methods |
The questionnaire consists of 3 phenomenological (based on main symptoms of depression) and 2 questions to assess functional impact of the symptoms. One hundred and ninety patients diagnosed clinically as having major depression (according to ICD-10 criteria and with the help of MINItool) filled the questionnaire in twice, during episode and remission.
Results |
At least two (out of three possible) “yes” answers to phenomenological questions and both two “yes” functional answers yielded 100% specificity (no person in remission). At least one “yes” answer to phenomenological questions and both “yes” answers to functional question yielded 82.8% specificity, 83.7% sensitivity and 83,3% overall accuracy. These results varied insignificantly in subgroups with different depression severity.
