Comments on an article by N. el-Guebaly et al. (see record 2012-24821-004). The authors provides an interesting and important transitional motif in the evolution of psychopathology research. These authors ask which other disorder does pathological gambling (PG) more closely resemble-addiction or obsessive-compulsive disorder? The article wishes to examine the similarity between a target disorder and two other disorders. The authors do not address three new complementary views of psychopathology. The efforts of the authors will develop the contours and methods of what will constitute the new science of psychopathology.
