Document Summary
Utility the extent to which the principles used in classifying an entity are effective in capturing the nature of the entity: e. g. Discrete entities, are mental disorders separated from each other? refers to the usefulness of the resulting classification scheme: e. g. Categorical approach: an entity is determined to be either a member of a category or not, qualitative difference between members of a category and those that are not, e. g. Living or non-living: you either have the disorder, or you do have it, all-or-nothing principle, no varying degrees of symptoms, nothing in between. Dimensional approach: an entity differs in the extent to which they possess certain characteristics or properties, quantitative difference among entities (more or less, e. g. Height, weight, sociability: difference in intensity of certain characteristics/symptoms, a(cid:272)he(cid:374)(cid:271)a(cid:272)h"s (cid:449)ork (cid:455)ielded t(cid:449)o (cid:271)road di(cid:373)e(cid:374)sio(cid:374)s of pro(cid:271)le(cid:373)s. Externalizing problems: acting out behaviours such as yelling, destroying things, stealing, showing aggression. Internalizing problems: feeling of sadness, worry, withdrawn behaviour.
