Psychopathology Flashcards
What is psychopathology?
The study of psychological disorders
What are the four definitions of abnormality?
- Statistical infrequency
- Deviation from social norms
- Deviation from ideal mental health
- Failure to function adequately
What is statistical infrequency?
Anything usual is seen as normal, anything unusual occurring occasionally, is seen as abnormal
What are the strengths and weaknesses of statistical infrequency?
+ Objective measure as it doesn’t rely on social norms or opinions
- Makes the assumption that any abnormal characteristics are automatically negative but this isn’t always the case
What is deviation from social norms?
Anything which is considered strange by the people of a particular society
What are the strengths and weaknesses of deviation from social norms?
+ Helps society: Adhering to social norms means that society is ordered and predictable
- Suffers from cultural relativism
- Depends on the time period
What is deviation from ideal mental health?
Suggests that abnormal behaviour should be defined by the absence of particular criteria - Jahoda’s criteria
What are Jahoda’s criteria for ideal mental health?
- Self-esteem
- Self-actualisation
- Independent and self-reliant
- Resistance to stress
- Mastery of environment
- Accurate perception of reality
What are the strengths and weaknesses of deviation from ideal mental health?
+ Positive approach as it focuses on what is helpful and desirable for the individual
- Unrealistic criteria and it’s impossible to achieve all of them
- Suffers from culture relativism
- Criteria is subjective and difficult to measure
What is failure to function adequately?
Circumstances where a person is unable to cope with demands of every day life
What are the strengths and weaknesses of failure to function adequately?
+ Take’s into account the patient’s perspective - the final diagnosis is comprised of the patient’s subjective self reported symptoms (accurate)
+ Represents a threshold for help - the criterion means that treatment can be targeted to those who need it most
- Could lead to labelling of a patient as crazy which isn’t useful if they already live a high quality life
What is a phobia and what are the 3 main types?
An irrational fear of an object or situation
- Specific phobia
- Agoraphoria: fear of a public place
- Social phobia (social anxiety): intense fear and anxiety in social situations
What are the behvaioural characteristics of phobias?
- Panic: crying, screaming, running away
- Endurance: the person remains in presence of the phobic stimulus but still experiences anxiety
- Avoidance: avoid coming into contact with the phobic stmiulus
What are the emotional characteristics of phobias?
- Anxiety
- Fear
- Irrational and disproportionate emotional response
What are the cognitive characteristics of phobias?
- Selective attention: the patient remains focused on the phobic stimulus even if it’s causing them anxiety
- Irrational beliefs
- Cognitive distortions: the patient doesn’t perceive the phobic stimulus accurately
What are the strengths of the behavioural explanation of phobias?
- Good explanatory power: Mowrer’s two-process model explains how phobias can be maintained - important implications for therapies as it explained why patients need exposure to feared stimulus(real-life application)
- Evidence for a link between bad experiences and phobias - the association between stimulus and UCR -> phobia (Little Albert)
What are the weaknesses of the behavioural explanation of phobias?
- An incomplete explanation of phobias: Bounton showed that evolutionary factors play a role in explaining phobias - Seligman called this biological preparedness (the innate predisposition to acquire certain fears)
- Some phobias don’t follow a traumatic experience: someone might fear snakes but have never encountered one - contradicts key aspect of mowrer’s model
- Ignores the cognitive aspects of behaviour: although behavioural explanation,including two-process model, is oriented towards explaining behaviour (avoidance) than cognition, phobias still have a cognitive element (e.g. irrational beliefs) - reductionist
What are the two behavioural approaches to treating phobias?
- Systematic desensitisation
- Flooding
What is systematic desensitisation?
- Aims to reduce phobic anxiety through gradual exposure to phobic stimulus
- Anxiety hierachy is constructed of situations involving the phobic stimulus
- Taught relaxation techniques and reciprocal inhibition takes place
- Patient works their way up hierachy until no anxiety is felt at highest level
What evidence did Gilroy et al provide for systematic desensitisation?
- Gilroy et al. (2003) followed up 42 people who had SD for spider phobia in three 45-min sessions
- At both three and 33 months, the SD group were less fearful than a control group treated by relaxation without exposure
What are the strengths of systematic desensitisation?
- Proven successful by Gilroy et al. (2003): a group of 42 patients who had systematic desensitisation as a treatment for arachnaphobia over 3 45 minutes sessions - at both 3 and 33 months they were less fearful compared to the control group
- Suitable for patients with learning difficulties: doesn’t require a huge cognitive load or evaluating their own thoughts
What are the weaknesses of systematic desensitisation?
- Less effective for evolutionary phobias: certain phobias, like heights, have an evolutionary survival benefit and are not the result of personal experience, but of evolution.
- Leads to symptom substitution: treats the symptoms not the cause - may leave patient vulnerable to other phobias developing as the root behind the fear has yet to be uncovered
What is flooding?
- Patient is exposed to phobic stimulus in a secure environment
- No option of avoidance behaviour so can’t be reinforced
- Phobia isn’t maintained
What are the strengths of flooding?
- Cost-effective: often only one session is needed, thus freeing them of their phobia and allowing them to live a normal life
- Works very well with ‘simple’ phobias e.g. phobias of one specific thing or object
What are the weaknesses of flooding?
- Less effective for complex phobias: social phobias involve both anxiety and a cognitive aspect - cognitive therapy would be more appropriate
- Traumatic: unpleasant experience, and If the patient panics and the treatment is not completed, it may leave them with an even worse fear/phobia of the object/event - waste of time and money
What is depression?
What are the four categories?
A mood disorder, where the sufferer experiences low mood and low energy levels
- Major depressive disorder: severe but short-term
- Persistent depressive disorder: long term including sustained major depression
- Disruptive mood dysregulation disorder: childhood temper tantrums
- Premenstrual dysphoric disorder: disruption prior to/and during menstruation
What are the behavioural characteristics of depression?
- Activity levels: could result in psychomotor agitation (can’t stay still) or low energy
- Changes in sleeping and eating behaviour
- Aggression and self-harm
What are the emotional characteristics of depression?
- Lowered mood: feeling worthless and empty
- Low self-esteem
- Anger
What are the cognitive characteristics of depression?
- Absolutist thinking: also called ‘black and white thinking’
- Poor concentration
- Selective attention to negative events
What is Ellis’ ABC model?
(define irrational beliefs)
A - Activating event: We get depressed when we experience negative external events and these trigger irrational beliefs
B - Beliefs: Irrational thoughts are any thoughts which interfere with us being happy and free from pain
C - Consequence: Emotional (depression) and behavioural consequences
