The Hamilton Depression Scale Factor

Share:

Description

Hamilton depression scale factor IV is a measurement of mixed anxiety and depression and it is named after its inventor. In a double-blind experiment, this scale factor is obtained for 9 patients on their entry in a study, denoted by X. Post a tranquilizer T, the scale factor IV is again obtained for the same set of patients, which is denoted by Y. Here, an improvement due to tranquilizer T corresponds to a reduction in factor IV values.
