Is psychological diagnosis in a strictly "medical" sense, possible?
It should be noted at the outset that current statutes that help to regulate professional practice in this area do use the term "diagnosis" in the medical sense of the term - i.e., identifying the cause of a disorder or disease by observing a patient's symptomatology. It seems clear from this that the cause is separate from its effects. It is however, not clear how a psychological condition can be both a symptom as well as a disorder. As it stands now, according to current accepted nosology(ies) in psychological practice there are numerous examples of psychological conditions that are both symptoms as well as disorders. It is important to note that there are altogether four separate classification systems used to "psycho-diagnose" a person in Canada. Added to this confusion is the fact that different schools in psychology have different and often conflicting explanations for disorders. Humanistically-oriented practitioners will often refrain from diagnosing a patient in the medical sense of the term. It is therefore, small wonder that differences of opinion should arise quite frequently in the mental health field making it vulnerable to ethical violations and legal uprisings. All this has surprisingly, not deterred the crown from implementing Acts and statutes that are apparantly meant to regulate the practice of diagnosis by mental health professionals. It is equally surprising that in spite of psychological science's infancy (only 100 years or so of experiments) and that prognosis and etiological factors are frequently fuzzy at best, it has not stopped therapists from designing such severe treatments as electro-shock, long-term use of neuroleptics and anti-depressants, aversive conditioning and so on. A related feature of this scenario is that there are physical conditions that are not yet understood by the medical community and are therefore, often being delegated to mental health professionals by other healthcare professionals (e.g., certain forms of chronic pain and fatigue). Nothing could be more dangerous!
