The process for classifying abnormal behaviour is:
In the science the classification is very important in studying the chemical elements, plants, planets or the people. The classification helps to study confidently to know and understand communication clearly. In the abnormal psychology, the classification involves undertake to describe a meaningful sub-varieties of maladaptive behaviour. Classification helps it to possible in communicating on certain clusters of abnormal behaviour in the agree-upon relatively precise ways.
Example: research cannot be conducted on the topic eating disorders until and unless the clinician has to start with the more or less clear definition of the behaviour under examination of the particular client.
It is very important to bear in mind that the formal classification is well accomplished only by precise techniques which are increasingly refined over the past years. There are three types of approaches in classifying the abnormal behaviour.
Dimensional approach: in this approach, it is assumed that a typical behaviour of a person is the product of differing strengths or the intensities of behaviour along with the various numbers of definable dimensions like mood, emotional stability, aggressiveness, gender identity and clarity of thinking and communication.
Dimensionally based diagnosis have incidental benefit of the directly addressing the various options for treatment. In taking dimensional approach, there is possibility to discover that the certain profiles tend to cluster together into types. Sometimes correlated, imperfectly, with recognisable sorts of the behavioural malfunctions like anxiety or depression.
The prototypal approach: the prototype is known as conceptual entity such as personality disorder that depicts an idealised mixture of characteristics which are more or less occur together regularly in a standard aspect in the actual observation level.
Categorical approach: in this approach the official diagnostic criteria define the different kinds of recognised classes of psychological disorders, that explicit intend in creating categorical entities, more oftenly not a result in prototypal ones. The more evidence identified disorders are of related somewhat to vague, the boundaries intending to separate from one disorder to another disorder. The evidence suggests that the strict categorical approach in identifying the abnormal and normal human behaviour in unataining the goal.
