Abstract

Oppositional Defiant Disorder (ODD) is analysed comprehensively based on successive and steady irate or crabby disposition, contentiousness/disobedience, and noxiousness. Since its initiation in the third Diagnostic and Statistical Manual of Mental Disorders, epidemiological and longitudinal examinations have firmly proposed an unmistakable presence of ODD that is not the same as other firmly related externalizing messes, with various course and result and potentially discrete subtypes.
