Various embodiments of the present invention relate to a method for predicting suicidal behavior in major depressive disorders based on frontal alpha asymmetry and frontal lobe activity asymmetry. According to various embodiments of the present invention, the method for predicting suicidal behavior in major depressive disorders based on frontal alpha asymmetry and frontal lobe activity asymmetry comprises the steps of: classifying a plurality of melancholiacs into a left brain type (LD) group and a right brain type (RD) group; measuring brainwave signals in a region of interest (ROI) related to frontal alpha asymmetry of the plurality of melancholiacs; calculating asymmetry indexes of a low alpha band and a high alpha band from the brainwave signals; checking an asymmetry index of a low alpha band of the melancholiacs belonging to the LD group and an asymmetry index of a high alpha band of the melancholiacs belonging to the RD group; and predicting suicidal behaviors of the melancholiacs by using the asymmetry index of the low alpha band and the asymmetry index of the high alpha band. Other embodiments are also possible.
