Anxiety and Depression

Short Description: Anxiety and depression are the most prevalent psychiatric disorders in Germany. The Patient-Health Questionnaire-4 (PHQ-4) is an ultra-short screening instrument that asks for the two core symptoms of both disorders during the previous two weeks. The PHQ-4 is a well-validated instrument with good reliability and criterion validity (Kohlmann et al., 2014).
