Often an incorrect interpretation or prognosis of an abnormal or extraordinary behavior pattern can draw the line between what is normal and acceptable, and what can suddenly be classified as a disorder or a disease. This paper aims to study the similarities between certain behaviors, and what factors can acts as differentiators between the two. The paper also emphasized how critical correct assessment is for correct prognosis, and that a treatment may thus, vary greatly from one disorder to another.Key concepts including “delinquency�, “antisocial behaviour�, “conduct disorder�, “conduct problems� and “externalising behaviour disorders� are often used interchangeably, however these concepts are far from identical (Connor, 2004). These are different definitions from different perspectives of psychology such as juvenile justice, clinical diagnostic/medical settings, psychometrics, and personality/social psychology in order to have a more complete understanding of antisocial behaviour and other related behaviours (Connor, 2004).
