Major Depressive Disorder Signs and Symptoms Hierarchy.
The person-Item map shows the severity scores for both the persons (top chart) and the items (bottom chart). The location (logits) is the measurement of the severity score (i.e., the higher is the logit, the more severe are the persons and the items). When any sign/symptom has the same Rash score of any person, it means that this person has a 50% probability to present that sign or symptom. So, any person that has a lower score of any item is less probable to present that sign or symptom; in contrast, any person that has a higher score of any item is more probable to present that sign or symptom.
