This explanation implies that there is a
correct way of behaving in society.
People who follow society's rules are
said to be normal and those who
deviate from these norms are said to
be abnormal.
It is also believed that
those who break the
unwritten rules of
society are abnormal.
Limitations
Social norms change
over time
For example homosexuality was
not removed from the mental
health classifications (DSM) until
1990. A true definition would not
have such variations over time.
Cultural issues
For example - it is normal in
some societies for people to
speak out loud to ghosts/spirits
, in our society that would be
seen as abnormal or a
symptom of a mental health
disorder. A true definition
would be appropriate across all
cultures.
Developmental
norms
For example - A 2 year old having a
tantrum becuase he/she didn't get any
sweets is normal. A 40 year old carrying
out the same behaviour would be
abnormal. These need to be considered
when looking at behaviour.
Statistical
infrequency
Abnormality can been seen as a statistically rare
behaviour - this can be seen on a normal
distribution curve. Those who behave in the
average way made up the middle of the bell-shaped
curve. However, those who make up the tails of the
curve are seen as 'abnormal'.
This explanation implies that the frequency of
the behaviour in the population determines
whether something is abnormal or not.
Strengths
Abnormality is on both sides of
the spectrum eg. weight (both
underweight and obese are
'abnormal')
Provides a clear cut off point for
defining abnormality (these
people can then get the support
they need)
Objective data
Easy to analyse and there is
no personal subjective views
to interfere with diagnosis
due to it being statistical
data.
Weaknesses
Undesirbale behanviour
may be common - It
would therefore be seen
as normal even when it
isn't ie. depression.
It's subjective at where the
'cut-off' point for abnormality
should be.
Deviation from ideal
mental health
This explanation defines positive
concepts and looks for an absence of
well-being. If you do not meet
Johoda's criteria you are at risk of
being abnormal.
Jahoda's criteria
Self actualisation
(realising your potential,
being fulfilled)
Positive self-attitude
(self-acceptance, high self
esteem)
Positive relationships
(ability to form warm,
close relationships)
Adaptation to the
environment (adapting
to life changing
circumstances,
resisting stress)
Accurate perception
of reality
Personal autonomy
(making your own
decisions, being
self-reliant/independent)
Weaknesses
Overdemanding
criteria
Most people do not meet
all of these criteria, so
according to this definition
most people are abnormal.
Subjective
criteria
Many of the criteria is
vague and is difficult to
measure, diagnosing
mental health is more
subjective.
Contextual
effects
Mental health criteria are
effected by context eg. spitting
whilst running is seen as
normal whereas spitting whilst
in a cafe is not.
Failure to function
adequately
This definition states that if someone can't
cope with the demands of every day life
then they are abnormal. If you meet more
than one of the criteria you are considered
abnormal.
The criteria
Maladaptive
behaviour
(behaviour that is
stopping someone
attaining their life
goals socially and
occupationally)
Personal distress
(affected by emotion to
an excessive degree)
Observer discomfort
(behaviour that causes
others to become
uncomfortable)
