The Answer is Answers will vary,but a full credit answer should contain the following points.
--Misconception 1: Psychiatric diagnosis is nothing more than pigeonholing-that is,sorting people into different "boxes." According to this criticism,when we diagnose people with a mental disorder,we deprive them of their uniqueness: We imply that all people within the same diagnostic category are alike in all important respects.
--Misconception 2: Psychiatric diagnoses are unreliable.As we learned in Chapter 2,reliability refers to consistency of measurement.In the case of psychiatric diagnoses,the form of reliability that matters most is interrater reliability: the extent to which different raters (such as different psychologists)agree on patients' diagnoses.The widespread perception that psychiatric diagnosis is unreliable is probably fuelled by high-profile media coverage of "duelling expert witnesses" in criminal trials,in which one expert witness diagnoses a defendant as experiencing schizophrenia and another diagnoses him as free of this disorder.
--Misconception 3: Psychiatric diagnoses are invalid.From the standpoint of Thomas Szasz (1960)and other critics,psychiatric diagnoses are largely useless because they don't provide us with much,if any,new information.They're merely descriptive labels for behaviours we don't like.When it comes to some popular psychology labels,Szasz probably has a point.Consider the explosion of diagnostic labels that are devoid of scientific support,such as codependency,sexual addiction,Internet addiction,road rage disorder,and compulsive shopping disorder.
--Misconception 4: Psychiatric diagnoses stigmatize people.According to labelling theorists,psychiatric diagnoses exert powerful negative effects on people's perceptions and behaviours (Scheff,1984;Slater,2004).Labelling theorists argue that once a mental health professional diagnoses us,others perceive us differently.Suddenly,we're "weird," "strange," even "crazy." This diagnosis leads others to treat us differently,in turn often leading us to behave in weird,strange,or crazy ways.The diagnosis thereby becomes a self-fulfilling prophecy.
