Abnormal Flashcards
(152 cards)
1
Q
what is abnormal psychology?
A
scientific study of abnormal behaviour emotion and cognition
2
Q
empirical method - description
A
Classification
Diagnosis
Delineate from different disorders
Very ongoing process
Aims to help us better understand classification and diagnosis
3
Q
empirical method - causation
A
Biological: gene, age, gender.
Psychological: able to cope, emotions, attitude, beliefs.
Social: family, economic status, friends, working, study, culture
4
Q
empirical method - treatment
A
Effectiveness
Randomised control trials - testing a treatment
Identify why some treatment methods are more effective.
Need good diagnosis + classification before enacting treatment
5
Q
The three D’s are used to
A
classify behaviour/condition as abnormal, must be a combination - cannot classify anything with only one D
6
Q
Deviant
A
Rare, inconsistent with social norms
may be positively valued - being extremely tall or fast
Some social norms change, such as homosexuality not being considered a mental illness anymore
Deviated from something
7
Q
Distressing
A
E.g. depression and anxiety
But distress is a normal part of life and you can have psychopathology without personal distress
8
Q
Dysfunctional
A
Interfering with day to day
E.g. adhd will interfere with day to day life
But some disorders don’t interfere with goals, and dysfunctional does NOT equal psychopathology
9
Q
issue with diagnosis
A
Presence of psychological abnormality mental disorder is not as readily definable as a physical illness
Definition of psychological abnormality reflect culture values and social norms
10
Q
supernatural approach to mental illness
A
Cause : demons, evil spirits, stars, moon, past live.
Treatment: exorcism, prayer, magic etc.
11
Q
biological approaches to mental illness
A
Cause: internal physical problems = biological function
Treatment: bleeding, diet, celibacy, exercise, rest, medication.
12
Q
psychological approaches to mental illness
A
Cause: beliefs, perceptions, values, goals, motivation - psychological dysfunction
Treatment: ‘talking therapy’/psychotherapy
13
Q
sociocultural approach to mental illness
A
Cause: poverty, prejudice, cultural norms
Treatment: social work to fix social ills, advocating for structural change
14
Q
integrative approach
A
bio-psycho-social model
15
Q
psychiatrist
A
Fully qualified medical Dr, prescribe medication. Specialised knowledge of the neurobiological feature of mental disorders
16
Q
clinical psychologist
A
Specialist training and qualification in psychological assessment, treatment, formulation and prevention of behavioural, mental and emotional health issues - takes bio-psycho-social approach
17
Q
registered/general psychologist
A
Less specialist and more generalist - treat people without serious/complex mental disorders
18
Q
social worker
A
- Work in direct service for example healthcare, welfare housing etc - Helping people cope with problems such as poverty, legal issues or human rights
- Work in the clinical field (more similar to psychologists) - Diagnose and treat mental, behavioural or emotional health issues.
19
Q
counsellor
A
Assist people to gain understanding of themselves and make changes in their lives
May simply provide a non judgemental ‘listening ear’
20
Q
abnormal
A
difficult to define, does not have one necessary or sufficient characteristic
21
Q
psychopathology
A
mental ill health. Has multiple causes, need to consider relationship between biological, psychological, social cultural factors
22
Q
biological/medical model
A
Dominant model in psychiatry, the underlying model of the DSM-5
Can be diagnosed similar to physical illness
Can be explained in terms of a biological disease process such as structural brain abnormalities (grey matter differences in schizophrenia) or neurochemical imbalance (depression)
23
Q
Biological Model: Criticisms & Limitations
A
Need to avoid extreme reductionism
Need to avoid over-extrapolation from animal research
Need to avoid assuming causation from treatment efficacy
May not be applicable to conceptualising and diagnosis of mental illness
24
Q
psychoanalytic model
A
Id + superego = const conflict. Ego tries to problem solve how to meet the needs of both.
25
ego
Conscious self (proposed to develop at around age 2)
Rational, organised, obeys ‘reality principle’
According to freud is what people see of you
Balances conflicting demands between id and superego
26
super-ego
Moral self (proposed to develop at age 5-6)
Develops through socialisation (right and wrong)
27
Id
Innate, instinctual self
Pleasure principle
Seeks immediate gratification of basic needs (hunger, sex etc.)
“Inner child”
28
If the ego is unable to resolve the conflict...
lead to anxiety, shame, guilt, embarrassment etc
29
To avoid the pain of unresolved conflict, the ego develops defence mechanism
Distorting id impulses into acceptable forms
Repressed id impulses into unconscious
Short term
E.g. oedipus complex
30
repression
unconscious mechanism - keep disturbing/threatening thoughts from becoming conscious
31
denial
blocking external events from awareness - too much to handle, refuses to experience it
32
projection
attributing own unacceptable thoughts/feelings/motives into another person
33
displacement
satisfying an impulse with a substitute object
34
regression
movement back in psychological time when one is faced with stress
35
sublimantion
satisfying an impulse with a substitute, in socially acceptable way
36
maladjustment
defence mechanisms excessively and/or rigidly applied (symptoms/suffering)
E.g displacement - depression
E.g projection - paranoia
37
Psychoanalytic Model: Diagnosis
2 people with the same underlying conflicts can have different symptoms
2 people with the same symptoms can have different unresolved conflicts, defences, etc.
38
Psychoanalytic Model: Treatment
Goal: to gain INSIGHT into unconscious processes
Develop awareness of the unresolved conflict and of the defence mechanism/s used
39
significance of psychoanalytic model
Revolutionised the concept of mental illness
Made no clear dividing line between normal and abnormal processes
Had a strong influence on the early development of the DSM
40
criticism/limitations of psychoanalytic model
Lacks empirical evidence
Unfalsifiable
41
behavioural model and phobias
If someone gets attacked in a park the reaction would be fear so people would avoid the stimulus (the park) and thus develop a pattern of avoidance.
Suggests both normal and abnormal behaviour comes from your learning history
42
cognitive-behavioural model
What we think influences how we feel and what we do
Currently the dominant model in clinical psychology
43
Cognitive behavioural therapy (CBT)
Aims to reduce (inflated) threat appraisal
Lower the probability x cost
“Something bad might happen but I will be able to cope”
44
emotional reasoning
assuming because we feel a certain way it must be true
45
labelling
assigning labels to ourselves or other people
46
personalisation
blaming yourself or taking responsibility for something that wasn't completely your fault. vice versa
47
all or nothing thinking
something called 'black and white thinking' -absolutes
48
mental filter
only paying attention to certain types of evidence - failure to take a wider perspective on situations
49
jumping to conclusions
mind reading and fortune telling
50
over-generalisation
seeing a pattern based upon a single event or being overly broad in the conclusion we draw
51
disqualifying positive
discounting the good things that have happened or that you have done for some reason or another
52
magnification and minimisation
blowing things out of proportion (catastrophising) or inappropriately belittling something.
53
treatment of cognitive distortions
Cognitive restructuring - challenging or testing irrational beliefs
behavioural experiments
54
why classify?
Identifying diagnosis categories can lead to specific treatment
Delineate from different disorders (difference between social and general anxiety)
55
why diagnose?
Improve communication
Improve understanding
May help reduce stigma
Will it help or hinder the patient if you tell them their diagnosis (BPD, Narcissistic personality disorder etc.)
56
Diagnostic and statistical manual of mental disorders (DSM)
American psychiatric association
1st edition: 1952
Currently it is the 5th edition, text revision: DSM-5-TR (2021)
Australia/USA/English speaking world.
57
International classification of diseases and health related problems (ICD)
World health organisation
Mental disorders added in 1948
58
changes in DSM
homosexuality removed (1973)
GAD introduced (1987)
binge eating disorder included (2013)
59
what does the DSM do?
Defines symptoms/criteria/differential diagnosis
Most agreed upon definitions/current consensus
Helpful but only a guideline
60
first editions of the DSM were problematic because...
Problematic reliability -can we agree on the diagnosis? Not a consensus on the diagnosis and was unhelpful?
Problematic validity - is this really what depression is? Based on unproven theories on causation.
61
DSM-5-TR (2021)
Reflects the medial/biological model
No theoretical assumptions about causation
Describes symptoms
62
Major depressive disorder
a single or recurrent depressive episode
63
Major depressive episode
1. Depressed mood most of the day, nearly every day
2. Markedly diminished pleasure/interest in activities
3. Significant weight loss or gain
4. Insomnia or hypersomnia nearly every day
5. Psychomotor agitation or retardation nearly every day
6. Fatigue/loss of energy nearly every day
7. Feelings of worthlessness, excessive guilt nearly every day
8. Diminished ability to concentrate nearly every day
9. Recurrent thoughts of death, suicide, suicide attempts
64
what is anxiety
Basic human feeling, evolutionary.
Warn us that something bad is about to happen
Both ‘abnormal’ and ‘normal' - activated in response to perceived threat
65
anxiety - physical
Fight or flight
Activated when there is a perceived threat
Alert
Dry mouth, fast breathing HR speeds up etc.
66
anxiety - cognitive
Perception of threat
Interpretation of the situation
Attentional shift towards threat, to better ‘survive’ the threat
Hypervigilance: we escaped, we didn't get hurt but we are now constantly scanning for the threat.
67
anxiety - behavioural
escape/avoidance: flight
Aggression: fight
Freeze
68
Anxiety has individual differences in
Trait anxiety - Tendency to perceive threat. Extent to which fight/flight is activated
Specific fear - abnormal anxiety
69
abnormal anxiety/disorders
Same systems are activated, but occurrence is excessive or inappropriate
Overestimation of cost or probability of harmful outcome (e.g. physical fears vs. social fears)
70
threat appraisal
Generates expectancy of harm - product of perceived probability (how likely will it harm me) x cost (how bad is this going to be for me)
past experiences/instructions
71
Panic attack specifier
abrupt and intense fear/anxiety - fear of dying/losing control/going mad
may be cued or uncued (panic disorder)
72
A panic attack is...
NOT a mental disorder, can occur out of the context of anxiety disorder
73
Panic disorder
uncued and unexpected panic attacks
anxiety/worry about having another attack because it is uncued - behavioural change to avoid this.
74
Cognitive Theory of Panic Disorder (Clark, 1988)
Individuals with a panic disorder have a higher sensitivity to bodily experiences - misinterpretation of bodily sensations.
75
Agoraphobia
Marked fear or anxiety of at least 2 of:
- Using public transportation
- Being in open spaces
- Being in enclosed places
- Standing in line or being in a crowd
- Being outside of the home alone
Excessive avoidance of situations where the person believes that escape might be difficult, or help might not be available, in the event of panic symptom
76
specific phobia
A marked and consistent fear reaction to the presence or anticipation of a specific object or situation - anxiety is out of proportion
77
subtypes of phobias
animals, blood/injection/injury, natural environment, situational/other
78
Onset of phobias
Childhood learning (could be vicarious) or following trauma
Common in children and more intense in adults
Typically a chronic course
79
Causes of specific phobias

learning/cognitive - accurate appraisal of past dangerous event OR inaccurate appraisal of harmless event
Evolutionary component
80

Fear that one will act in a way or show anxiety symptoms that will be negatively evaluated
81
how do people with SAD think
Assume that others are highly critical
Place a great importance on the evaluation of others
Negative self-evaluation
Provoke immediate anxiety
Self preoccupation and attention on the anxiety
82

High trait anxiety
Intolerance of uncertainty
Positive and negative beliefs about worrying (meta beliefs). “Thinking about your thinking”
Reduced problem solving confidence
85
obsessions
repeated intrusive, irrational thoughts or impulse which cause anxiety/distress - Thinking about killing someone feels the same as actually killing someone.
overt - washing hands
covert (cog) - counting to 10
86
compulsions
ritualised behaviours to relieve the anxiety caused by obsessions.
logical/illogical
87
common obsessions in OCD
contamination
harm
aggression/losing control
perfectionism
religion
unwanted sexual thoughts
88
Cognitive factors/process associated with OCD:
Intolerance of uncertainty
Inflated responsibility
Thought-action fusion (TAF)
Magical ideation: illogical connections between obsessions and compulsions.
89
psychoeducation
improve knowledge of mental illness
understanding what is happening
role of thoughts and avoidance
avoidance is brings temporary relief
anxiety is natural but can be excessive/inappropriate
90
cognitive techniques
thought diaries - make client more aware of their thoughts and identify patterns
cognitive restructuring/thought challenging - what is the evidence, is it helpful, different perspectives
91
exposure therapy
exposing individuals to feared stimulus and keeping them in that state to prove that nothing happens and anxiety decreases
92
Systematic desensitisation vs. flooding
Slowly building up to the situation that provokes the most anxiety is the best for exposure therapy
93
Exposure effects cognition
Exposure to stimuli reduces estimate of probability
Exposure to outcome reduces estimate of cost
94
medication
Treating symptoms but not the cause
side effects and relapse - isn't used on its own
95
Depressive disorders
Characterised by a disturbance of mood
Mood exist on a continuum
Extreme low mood
96

Women are twice as likely to have a depressive disorder (but also could be more likely that they have a higher behaviour to seek help)
High comorbidity with anxiety and substance abuse
103
Schema Theory (Beck, 1976)
(Pre-existing negative schemas + Stress) leads to (Depression)
104
cognitive triad
negative view of the:
self
world
future
105

Scheduling time for pleasant activities
Make it homework, work towards goals
Break lethargy cycle
107
Selective Serotonin Reuptake Inhibitors (SSRIs)
e.g. Prozac, Zoloft, etc
fewer side effects than older drugs
Effectiveness: 70-80%
108
Electroconvulsive Therapy (ECT)
Involves applying brief electrical current to the brain
uncertain how/why ECT works
Last resort: effective for severe depression (80%)
109
Anorexia Nervosa (AN)

110
AN - Restricting
Individual has not eaten or taken in binge eating behaviours
Diet, fasting, excessive exercise.
111
AN - Binging/Purging
Self induced vomiting, improper use of laxatives etc.
Bingeing in anorexia nervosa is different because the individual may view eating a punnet of strawberries a “binge”
112
Onset and course of AN
Most common age is between 12-25.
5-7 years, slow recovery (egosyntonic, they view the disorder as part of how they are, recovery would be having a higher BMI and changing their cognitions). ~40% of people with AN will later develop Bulimia Nervosa.

serious psychological disorder characterised by:
Recurrent episodes of bingeing
(compensatory) behaviours that prevent weight gain
Distorted body image
BMI could still be normal
118
Recurrent episodes of BINGE EATING

2. taking stock - reviewing progress and planning
3. addressing maintaining mechanism - body image, dietary restraint, events, mood, eating
4. ending well - identify goals/residual problems, prevents relapse
127
What are the main problems associated with diagnosing an individual with a psychological disorder?
Hinder the ability to be further diagnosed - put in a box
Diagnosis may have a stigmatising effect on the individual
128
What are the advantages of diagnosing an individual with a psychological disorder?
Better understand how they feel and think and why - underlying pathology (aetiology)
Allow them to be put on medication to help them - treatment
What their prognosis is - what are the next steps
129
Incidence:
the number of new cases occurring during a specified time. It can also be thought of as the infection rate, or the probability (risk) of contracting the disease.
130
incidence rate =
New instance of disease in population ÷ Duration in which individuals are at risk of contracting disease
131
prevalence
the prevalence of a disease is the proportion of the population that have the disease at a given time
132
prevalence rate =
Total cases of disease in population at a given time ÷ Total number of individuals in the population at risk

Strongly related to anxiety
134
Post-traumatic stress disorder (PTSD)

2. Persistent avoidance of any reminders of the event
3. Negative changes in cognition and mood, which can involve fear, helplessness, self-blame, anger or hopelessness
4. Changes in arousal and reactivity, which can manifest in sleep disturbance, poor concentration, hypervigilance, exaggerated startle responses, and reckless or impulsive behaviours.
135

Suspicion, anxiety, anger may accompany delusions.
Hallucinations may occur.
146
disorganised schizophrenia
Confusion and incoherence, severe deterioration of adaptive behaviour (personal hygiene, social skills, self-care etc).
Difficult to communicate with individuals in this subtype
Behaviour may appear silly/childlike
Inappropriate emotional responses
147
catatonic schizophrenia
Striking motor disturbances ranging from muscular rigidity to random or repetitive movements.
Alternate between stuporous state and agitated excitement (they can become a danger to others in this state)

148
negative symptoms of schizophrenia
absence of normal interactions

150
Brain abnormalities in schizophrenia
Destruction of neural tissues can cause schizophrenia
Brian atrophy and enlarged ventricles
Abnormalities in thalamus
Structural differences are common in those who experience negative symptoms.
151
dopamine hypothesis
Symptoms (mostly positive) are produced by overactivity of the dopamine symptoms in areas of the brain that regulate emotional expression, motivated behaviour and cognitive functioning
More dopamine receptors on neuron membranes
Antipsychotic drugs - reduce dopamine-produces synaptic activity
