Thank you for the opportunity to help you with your question!
Nail biting can be defined as a habit because it is a
behavior that is learned during the process of growth and development and
therefore become automatic and people with the habit are usually unconscious of
this action when they are doing it. Nail biting can be defined as a disorder because
it is an obsessive compulsive disorder in the sense that individuals suffering
from this disorder do it repeatedly in a routine manner. In addition, certain
psychological states such as stress or depression can provoke or increase the
intensity of this disorder.
Between-subject method can be used to determine if nail
biting is a habit or a disorder by placing participants with this behavior in
different categories. One group of subject should be treated with medication
used for treating obsessive compulsive disorder while the other group of
subjects should be helped to unlearn the habit by keeping their nails short and
be discouraged from nail biting. The results for the two different treatments
for the subjects are then compared. If the results of treatment for obsessive
compulsive disorder show more improvement or cessation of nail biting, then the
condition can be regarded as a disorder. If the other results from unlearning
of the habit show the cessation of nail biting, the condition can be regarded
as a habit.
