Symptoms: experienced by the
individual and used to diagnose the
mental health disorder
Positive: add to normal
behaviour, or change normal
behaviour, can be affected by
cultural differences, hold a
greater weight in diagnosis
Thought insertion: A
person thinks their own
thoughts have been
implanted by someone
else, an external force
over which they have no
control.
Hallucinations: Experiencing something
that is not really there through one of
the five senses, e.g. hearing voices or
seeing things that aren’t there. For
auditory hallucinations (most common
in schizophrenia), the voice is often
harsh and critical – they may provide a
commentary of what the person is
doing or control the person by giving
orders.
Delusions: A delusion is a
firm belief or idea that
conflicts with reality; a false
belief. E.g. thinking their
behaviour is being
controlled by someone else.
Grandiose delusions: holding false
beliefs about being in a position of
power, e.g. false beliefs about being
a king or possessing a special power
such as the cure for cancer.
Persecutory delusions: holding false beliefs that
others are trying to harm them in some way, e.g.
falsely believing someone is spying on them or
plotting against them. Referential delusions:
holding false beliefs that unrelated information is
directly related to them. E.g. the false belief that
newspaper headlines hold secret messages for
them.
Disordered thinking: Muddled
thinking that may make speech
disorganised and hard to follow.
They will find it difficult to
organise their thoughts logically
and may speak in a “word salad”
of unconnected words and
phrases. They may stop
mid-sentence, as if the thought
has left their head, jump from
topic to topic, and may make up
words that have no meaning,
called neologisms.
Negative: remove something from
normal functioning, easier to
operationalise and measure
objectively, may start before positive
symptoms (years before diagnosis)
Flatness of emotion:
Reduction in emotional
expression, e.g. lack of facial
expressions, lack of eye
contact and a dull monotone
voice.
Social withdrawal: Avoidance of
interaction with friends and family
and/or not going out
Lack of energy and apathy:
“avolition” No motivation for
carrying out normal daily tasks,
such as work.
Lack of pleasure: Not
experiencing pleasure
from previously enjoyable
activities such as hobbies,
social interaction, sex and
exercise.
Features: facts that
describe the mental
disorder such as statistics
The average life expectancy for
individuals with schizophrenia is ten
or more years less than average, due
to health problems associated with
the disorder or higher suicide rate.
The NHS suggests that 1% of
people will experience at least
one episodic of acute
schizophrenia in their lifetime.
Goldstein (1988): Male sufferers
experience a more severe course of
schizophrenia than females (more visits
to and more time in hospital)
To be used as ONE
feature. Each fact
individually is not ONE
feature.
¼ of patients will have one
episode of schizophrenia then fully
recover.
¼ of patients will suffer chronic
(long-term) schizophrenia.
½ of patients will have occasional
schizophrenic episodes.
Schizophrenia tends to be
diagnosed during
adolescence up to about
age 30.
It is a universal disorder, affecting
both males and females, but it has
an earlier average onset amongst
males (early to mid twenties in
males, compared to late twenties
in females).
Positive symptoms
are more treatable
than negative
symptoms
