Depression is assessed by both the patient’s complaints and the scale assessment. The main scales include the following: Depression Self-Rating Inventory, Anxiety Self-Rating Inventory, Minnesota Personality Inventory, Parenting Style Questionnaire, and Marital Quality Questionnaire. From these questionnaires, patients can be evaluated from multiple perspectives, including feelings, behaviors, thinking, personal habits, eating habits, interpersonal relationships, and sleep status, to assess the occurrence and severity of depression. The patient’s complaints are mainly descriptive, such as depressed mood, low mood, disinterest in everything, decreased energy, low self-esteem, slow reaction, weight loss in a short period of time, and insomnia, etc. From these complaints, we can determine whether the patient has depression and its severity.
