A
Behaviour, speech or thoughts that impair the ability of a person to function in a way that is generally expected of them, in the context where the unusual functioning occurs
3
Q
Mental illness
A
Often used to convey the same meaning as psychological abnormality, but medical not psychological cause
4
Q

Q
What does DSM-5 stand for?
A
Diagnostic and statistical manual of mental disorders (of the American psychiatric association, 2013)
7
Q
Name and describe each concept in attempts of “defining abnormality”
A
1- statistical concept (aka behaviour does not occur frequently in the population, exceptional, Sidney Crosby)
2- personal distress (but distress not always present in people identified as abnormal; everyone distressed sometimes)
3- personal dysfunction (behaviour interferes with appropriate functioning, but what is approp functioning?; interesting link to evolutionary psych)
4- violation of norms (cultural)
5- diagnosis by an expert
8
Q
“How we define abnormality is culturally relative”
A
The norms of a culture determine what is considered normal behaviour, and abnormality can be defined only in reference to these norms

Criticism of DSM as it classifies people as either having disorders or not having them, with no in-between
Doesn't provide a meaningful description of an individual's psychological problems
Dimensional approach suggested (continuum)
109
Clinical utility
Goal of DSM-5
Extent to which a diagnostic system assist clinicians in performing functions like communicating clinical info to patients/their families/other healthcare providers, selecting good treatment, predicting course of disorder
That's why DSM-5 introduced a scale for assessing the severity of psychotic symptoms to help clinicians make a prognosis
110
Arguments against classification of disorders
- shouldn't use medical model
- creates stigmatization
- loss of information
111
Criticisms specific to the DSM

- doesn't take life circumstances into account enough
- cultural bias
- influence of politics
112
Single-factor explanation
States that a genetic defect or single traumatic experience causes a mental disorder
Attempts to trace origins of a disorder to one factor

113
Interactionist explanation

Takes biology and environment into account
114
Null hypothesis
Proposes that prediction made from theory is false
115
4 general aims of theories about mental disorders
1- explain the etiology (cause or origin)
2- identify factors that maintain the behaviour
3- predict the course of the disorder
4- design effective treatments
116
Name the six main theories about etiology of mental disorders
1- biological
2- psychodynamic (Freud)
3- behavioural/cog-behavioural
4- cognitive theories examining dysfunctional thoughts or beliefs
5- humanistic/existential theories that examine interpersonal processes
6- socio cultural influences
117
4 general aims of theories about mental disorders

2- identify factors that maintain the behaviour
3- predict the course of the disorder
4- design effective treatments
118

2- psychodynamic (Freud)
3- behavioural/cog-behavioural
4- cognitive theories examining dysfunctional thoughts or beliefs
5- humanistic/existential theories that examine interpersonal processes
6- socio cultural influences
119
Characteristics of biological theories
- borrow model from medicine
- use vocab like patients, symptoms, syndromes, treatment
- say that issues are from dysfunctions or damage in the brain (central nervous system), problems of control in peripheral nervous system (automatic/somatic nervous system), or malfunctioning of endocrine system
120
4 goals of a theoretical perspective
Explain etiology
Identify factors maintaining disorders
Predict course of disorders
Design effective treatments
121
How has historical perspective shifted?
Past: emphasis on bio OR enviro causes (nature vs nurture)
Now: interactionist explanations
122
Where/what causes mental disorders according to biological models?
```
Damage to brain
Neurotransmitters
Autonomic nervous system (ANS)
Endocrine system
Genetics
```
123
Some disorders have been linked to brain damage. How can damage occur?
Direct head injuries
Diseases
Toxins
124
Neurotransmitters
Chemical messengers that are released from the propagating neuron and move through the synapse to the postsynaptic neuron
125
4 neurotransmitters that get the most research attention
Dopamine
Serotonin
Norepinephrine
Gamma aminobutyric acid (GABA)
126
Dopamine vs serotonin caused behaviour
Dopamine: pleasure seeking and adventurous behaviours
Serotonin: constraint or inhibition of behaviours
127
How are neurotransmitters distributed in the brain?
Different neurotransmitters seem to be concentrated in diff areas of the brain
Relate to diff functions
128
4 disturbances in neurotransmitters that can contribute to abnormal behaviour
1- production/release at the synapse
2- receptor sites
3- transmitter deactivating substance in the synapse
4- reuptake process
129
Peripheral nervous system is made of two parts
Somatic nervous system
| Autonomic nervous system
130
Somatic nervous system
Controls muscles (chronic muscle tension, symptom of generalized anxiety disorder)
131
Autonomic nervous system
Controls bodily functions like breathing, digestion, heart rate, etc
Split into parasympathetic nervous system and sympathetic nervous stem (fight or flight response)
132
Endocrine system
Endocrine glands release hormones (chemical messengers released into bloodstream)
133
What do disturbances in hormone balance cause?
Disruptions in behaviour, thoughts and feelings
134
What problem can mimic anxiety and is related to hormones and the endocrine system?
Hypoglycaemia
| Pancreas doesn't secrete balanced levels of insulin or glycogen
135
Genetics
Inherited characteristics
Genes interact with environment to lead to psychopathology (ex: adults with a specific gene developed depression only if they also experiences a stressful life event)
136
The 5 psychosocial theories
```
Psychodynamic theories (unconscious conflicts)
Behavioural theories (learning causes normal or abnormal behaviour)
Cognitive theories (thoughts cause dysfunction)
Humanistic/existential theories (considers each person's idiosyncrasies, person's sense of self=important, people are in control of their actions)
Socio-cultural theories (stereotypes of gender, race, poverty, labelling cause disorders
```
137
Psychodynamic theories
Sigmund Freud
Theory based on analysis of Anna o.
To explain all aspects of human behaviour, including neurosis
138
What are Freud's 4 interrelated aspects that produce behaviour (psychodynamic theory)
Levels of consciousness
Structures of personality
Psychosexual stages of development
Defence mechanisms
139
Freud's 3 levels of consciousness (psychodynamic theory)
Conscious: info we are aware of
Preconscious: info that is accessible although it is not in our awareness
Unconscious: stores memory/drives that would require great effort (psychoanalysis) to bring to awareness
140
Freud's structures of personality (psychodynamic theory)
Id: biological or instinctual drives (ex: sexual, aggressive, etc); pleasure principle
Superego: internalization of societal values and morals
Ego: mediator between id and superego; maximize benefits against costs; reality principle
141
Freud's 5 psychosexual stages of development and their manifestations (psychodynamic theory)
Oral (birth to 18 mos; focus on oral activities)
Anal (18 mos to 3 years; child may cooperate or resist toilet training by soiling or withholding)
Phallic (3-6 years; Oedipal or Electra complex)
Latency (6-12 years; consolidation of behavioural skills and attitudes)
Genital (teen-death; achievement of personal and sexual maturity)
142
What is the function of defence mechanisms? (Psychodynamic theory)
Express desires of the id in symbolic form (unconscious) or to manage anxiety
Ego uses defence mechanisms and the id does its best to break through these defences
143
Three examples of defence mechanisms (psychodynamic theory)
Denial
Reaction formation (repressing unacceptable desires by expressing the opposite to what you really mean)
Projection of feelings/beliefs onto others
144
Criticisms of freud's theory
Largely speculative and hard to test
No matter what the results are, the theory can still explain it
BUT he did open up discussion about sexual research, not all reasons for human behaviour are the obvious ones, etc
145
Three examples of projective tests used for personality assessment
Rorschach ink blot test
Thematic apperception test (TAT)
Minnesota multiphasic personality inventory (MMPI)
146
What is the main belief of behavioural theorists?
All behaviour is learned (Watson)
| Basis for this learning=classical conditioning (Pavlov, dog experiment)
147
Two types of conditioning (behavioural theories)
```
Classical conditioning (Watson)
Operant conditioning (skinner)
```
148
Describe classical conditioning and its stimuli/responses (behavioural theories)
Unconditioned stimulus: automatically causes a response
Conditioned stimulus: neutral; does not naturally cause the response associated with the UCS
Unconditioned response: automatic response to UCS
Conditioned response: learned response to the conditioned stimulus after pairing with the Unconditioned stimulus
149
Describe the case of little Albert (behavioural theories)
White rat=conditioned stimulus
Loud noise=unconditioned stimulus
Elicits fear response
150
Problems with classical conditioning (behavioural theories)
Couldn't explain why phobias did not go away; after using the conditioned stimulus without unconditioned stimulus- expects that the conditioned stimulus will then stop giving the response
151
Three main ideas of operant conditioning (behavioural theories)
Consequences of behaviour=important
Both positive and negative reinforcement increase behaviour
Punishment decreases likelihood that behaviour will reoccur
152
Social learning theory (behavioural theory)
Although some behaviours are acquired directly by conditioning processes, observation leads to the formation of most behaviours
Lead to development of cognitive behavioural theory
153
Cognitive-behavioural theory (behavioural theories)
Has roots in social learning theory because Bandura emphasized the importance of cognitive processes
Introduces idea that individuals play an active role in regulating their behaviour and thoughts
Beck=because behaviours and thinking are learned, they can be changed
Therapeutic tool=self-monitoring
Automatic thoughts -> cog distortions
Schemes -> info processing and immediate beliefs -> auto thoughts
154
The 4 interactionalist models
Systems theory
Diathesis-stress perspective
Biopsychosocial model
Developmental psychopathology
155
Systems theory (interactionalist theory)
Whole is greater than the sum of its parts
| Causation as multifactorial and bidirectional (parents behaviour causes child's behaviour and vice versa)
156
Diathesis-stress perspective (interactionalist theory)
According to this model, people are predisposed to develop a disorder (diathesis) but a stressor is needed start the symptoms (diathesis + stressor= symptoms)
Diathesis or stressor can be biological or psychological
Pros= encourages us to consider multiple factors in onset of a disorder; shows that reason one person gets a disorder could be different than the reasoning of another person
157
Biopsychosocial model (interactionalist theory)
Biological, psychological, and social factors important
| Each factor must be taken into account, with the weighting of each factor depending on the disorder
158
Developmental psychopathology (interactionalist theory)
Crosses boundaries of social, psychological and bio sciences
Multifactorial causation
Multiple pathways to same outcomes
Profiles of risk/protective factors
Maladaption= outcome of development
Dynamic vs static (processes that underlie development always changing)
159
Three types of mood episodes
Major depressive episode
Manic episode
Hypomanic episode
160
Three types of mood episodes
Major depressive episode
Manic episode
Hypermanic episode
161
Describe characteristics of a major depressive episode
5+ symptoms within less than a two week period and must have either depressed mood or diminished interested pleasure (other symptoms include weight/appetite change, insomnia, motor agitation/retardation, loss of energy, worthlessness/guilt, thoughts of death or suicide attempt)
162
Characteristics of a manic episode
1- abnormal/irritable mood and increased energy or goal-directed activity in min 1 week
2- 3+ symptoms (includes inflated self-esteem, less need for sleep, more talkative than usual, flight of ideas, easily distracted, more goal-directed activity or fidgety, involved in a lot of risky but pleasurable activities)
163
Hypomanic episode
Same symptoms as manic episode but lasts less than 4 days (vs 1 week) and episode not serious enough to cause marked impairment at work/social activities, no need for hospitalization, no psychotic features
164
What kind of episodes go with each of the three main mood disorders
Major depressive disorder= only major depressive episode
Bipolar 1= 1+ manic episodes and with or without depressive episodes
Bipolar 2= 1+ hypomanic episodes and with 1+ depressive episodes
165
Characteristics:
- depressed mood most days
- two or more symptoms (appetite issues, sleeping issues, low energy, low self esteem, bad concentration, hopelessness)
- 2+ years (or 1 for kids and teens)
Persistent depressive disorder
166
Characteristics:
- 2+ years (1 for kids and teens)
- periods of hypomanic symptoms and depressive symptoms but doesn't match criteria for major depressive episode
- during 2 years, not without symptoms for more than 2 mos at a time
- be careful with antidepressants because can cause mania in sensitive patients
Cyclothymia
167
Unipolar vs bipolar nods disorders
Unipolar: major and persistent depressive disorder
Bipolar: bipolar 1 and 2, Cyclothymia
168
Premenstrual dysphoria disorder (PMDD)
- 5+ symptoms week before period and improve a few days after period starts
- 1+ of: marked affective instability, irritability, depressive mood, anxiety
- 1+ of: decreased interest, sleep and appetite changes, physical symptoms
- must be determined by watching for symptoms for two months before actual diagnosis
169
Gender bias in PMDD?
Callaghan study: when describe in sex-specific form, 20% of women met criteria
When described in sex-neutral form: only 8% of women and also 4% men
170
Cognitive theory of depression
- How individuals think about and see their world impacts feelings and behaviour
- schemas of depressed people are highly negative
- cognitive triad: negative core beliefs about self world and future
- longitudinal studies show that people with negative cognitive style were more likely to develop depression
171
Beck's diathesis-stress model of depression.
Negative cognitive schemas (diathesis) are inactive until individuals face a life stressor that matches the theme of their schema
Ex: I'm a failure activated by failing a course
172
Cognitive-behavioural therapy for depression (3 stages of treatment)
1- behavioural activation by activity scheduling, etc
2- identifying accuracy of automatic thoughts (all or nothing thinking, over generalization, magnification/catastrophizing, jumping to conclusions)
3- challenge a patient's core beliefs and schemas (behaviour experiments that view thoughts as hypotheses that can be tested, collect evidence for and against auto thoughts)
173
Three main points of evidence for cognitive behaviour therapy for depression
- better than no treatment and psychodynamic therapy
- comparable to meds
- lower relapse rates compared to people just taking meds
174
Interpersonal characteristics of depression
- deficits in social skills
- more negative interactions
- less eye contact/face animation/modulation of tone of voice
175
Do deficits in social skills cause depression?
No
| Risk factors are actually negative feedback seeking and excessive reassurance seeking
176
Describe interpersonal psychotherapy (IPT)
Developed in 1980s by klerman and Weismann
Roots in psychodynamic theory but a brief treatment (12-16 sessions)
Suggests that depression develops in an interpersonal context and therefore addressing people's difficulties in relationships should help improve the depression
177
IPT's four domains that are targeted sources of interpersonal dysfunction
1- interpersonal disputes
2- role transition
3- grief
4- interpersonal deficits
178
Tricyclics (depression)
Block reuptake from synapse of NE (catecholamine norepinephrine) and indolemine serotonin (5-HT)
Causes more neurotransmitters to be available in the synapse to bind to post-synaptic receptors and trigger new action potentials
Effective but has many side effects
Lethal in overdose
179
Monoamine oxidase inhibitors (MAOIs; depression)
Inhibit monoamine oxidase (an enzyme) that breaks down monoaminergic neurotransmitters in the presynaptic cell. This causes more monoamines to be released into synapse to bind to post-synaptic receptors and trigger new action potentials
Has potentially dangerous side effects
180
Selective serotonin reuptake inhibitors (SSRIs)
First choice in treatment of depression
Mild side effects
Only need to take once a day
Block the reuptake of serotonin into the presynaptic cell. More serotonin in the synapse to bind to post-synaptic receptors and trigger new action potentials.
181
50-70% of patients response to antidepressants. How do you choose which one to use?
```
Decision based on:
Side effects
Ease of administration
History of response with the person or members of the family
Medical issues
Depressive subtype
Cost
```
182
Is combined CBT, IPT and medication effective?
Not for mild to moderate depression, but yes for severe depression or depressed teenagers
183
Etiology of bipolar disorder
Heritability is .75 (vs .36 for major depressive disorder)
| Sleep deprivation triggers mania for many patients
184
Medication is the best way to treat bipolar disorder, but has high rates of relapse. What are the drugs typically used?
- lithium (don't know how it works, requires regular monitoring, therapeutic dose is just less than toxic dose)
- anticonvulsants
- antipsychotics (short term, risk of tardive dyskinesia)
- antidepressants (risk for triggering mania, used usually with mood stabilizers like ones listed above)
185
CBT for bipolar disorder
Similar to treatment for depression PLUS
Problem solving around sleep difficulties
Mood monitoring to identify triggers for mania
Support taking meds regularly
186
Interpersonal and social rhythm therapy (IPART) for bipolar disorder
Focus on regulating daily routines and teaching coping methods for stressful events
Few relapses compared to clinical management
187
Electroconvulsive therapy for bipolar disorder (ECT)
Used today for people with severe mood disorders when no other treatment has worked for them
Risk of memory loss
188
Vocab:
1- thoughts of death/suicidal plans
2- non-fatal attempt at suicide with intention to die
3- death by suicide
1- suicidal ideation
2- suicide attempt
3- completed suicide
189
Suicide stats
Almost 1 million people die of suicide every year
Men complete suicide more than women, but women attempt it more
2nd leading cause of death in young people in Canada and leading in Canadian males aged 15-19
190
The two high risk groups for completed suicide
1- males 19-24 and over 70
| 2- First Nations living in reserves
191
Primary prevention of suicide
Population based
Focus on changing situations/attitudes/conditions that predispose individuals towards suicide
(Public education has had little success and restricting access to suicide means has had some success)
192
Secondary/tertiary prevention of suicide
Target individuals high in suicidal ideation or behaviours
Suicide hotlines are most helpful for suicidal ideation; helpful in reducing female suicide rates but not so much in general rates
193
What are the American association of suicidology's warning signs of suicide?
IS PATH WARM
194
Deliberate harm to ones own body tissue (ex: cutting, burning, head banging; no suicidal intent)
Non-suicidal self-injury (NSSI)
195
4 high risk groups for most risk to least risk
Forensic populations, undergraduates, psych patients, adolescents
196
Course of NSSI
Onset typically in adolescence, can be chronic
197
Risk factors for NSSI
```
Childhood maltreatment
Depression
Difficulty regulating emotions
Self-criticism
Parental criticism
Social conflict and isolation
```
198
5 reasons why people self-injury
```
Emotion regulation
Reduce anger
Communicate distress to others
Self-punishment
End dissociative experiences
```
199
Clinical concerns of self-injury (4)
Associated with increase risk of suicide attempts and completion
Associated with shame, guilt and regret
Disrupts relationships
Can lead to scarring and infection
200
Biological factors of anxiety
- genetic influence: 4-6 times more likely if family member had it
- neural fear circuit: thalamus, amygdala, hypothalamus, mid-brain, brain stem and spinal cord
- seratonin and norepinephrine systems
- GABA=most pervasive inhibitory neurotransmitter in the brain
201
Mowrer's two factor theory (anxiety)
Fears are acquired through classical conditioning
Fears are maintained through operant conditioning
Ex: escaping= negative reinforcer that stops classically conditioned fears from being unlearned
Limitations: can't explain the development of all phobias (we are biologically made to be afraid of dangerous things)
202
Beck's cognitive model (anxiety)
Anxious people think the world is dangerous, the future is uncertain, and the self is helpless/vulnerable
203
Interpersonal factors in anxiety
Relationships we make with our parents early in life can lead to the development of general belief systems about relationships
Anxious-ambivalent style is most likely to lead to anxiety in adulthood
204
Criteria for a panic attack
At least 4 of the 13:
- fast heart beat
- sweating
- shaking
- shortness of breath
- feelings of choking
- chest pain
- nausea
- feeling dizzy or faint
- derealization/depersonalization
- fear of losing control or going crazy
- fear of dying
- paresthesias (numbness/tingling)
- chills/hot flashes
205
Panic disorder
Two or more unexpected panic attacks
Attack must develop suddenly and randomly (uncued)
Always worrying about having another attack or altering behaviour because of them
Medical conditions or other anxiety disorders mimic these symptoms but here the attacks are for no apparent reason
Can be assessed with symptom induction test
206
Panic disorder: etiology (2 cognitive theories)
Catastrophic misinterpretation
| Alarm theory
207
Agoraphobia
Anxiety about having an anxiety attack in a place where help cannot easily reach the person or they cannot escape (ex: public transit, open spaces or enclosed spaces, standing in line or crowds, etc)
208

2- difficult to control the worry
3- 3 of 6 symptoms:
Restlessness
Tired easily
Difficulty concentrating
Irritable
Muscle tension
Sleep disturbance
4- focus of anxiety not confined to another anxiety or axis 1 disorder
```
211

Repetitive behaviours due to obsessions=compulsions (goal of reducing anxiety)
212
Thought-action fusion
Related to OCD
Belief that the more you think about about something, the more likely it is to come true
Also thoughts = action in this person's head (same moral goodness or badness)
213

Cognitive restructuring
215
Describe the exposure technique called systematic desensitization
1- develop a hierarchy (ranking) of experiences that cause the person anxiety (using subjective units of distress)
2- gradually go through the list and teach the person how to cope with their anxiety in each situation through demonstration
216
Describe relaxation through guided imagery
Develop an image that make one feel calm and relaxed

Two points of empirical support for relaxation strategies
1- they provide immediate (but short term) relief
| 2- exposure is the most important part of the treatment

Name 4 ways that disturbances in neurotransmitter systems can cause abnormal behaviour
1- too much or too little neurotransmitter produced or released into the synapse
2- too few or too many receptors in the dendrites
3- excess or deficit in the amount of substances that stop neurotransmitters in the synapse
4- reuptake process could be too fast or too slow
230
Humanistic/existential theories
Husserl/merleau-ponty
People form their view of the world through experience which sense of self guides
Involves free will
Humanistic=Rogers and Maslow (experience=basis for improving oneself; must trust experience)
Hierarchy of needs to reach self-actualization
Existential=possibility of death or loss of meaning in our lives along with the responsibility for our actions makes us anxious
Both have little research
231

Diathesis-stress model
234
Candidate gene for depression

235
How is stress modulated in mammals?
Hypothalamic-pituitary-adrenal axis
| Stress releases CRH which leads to ACTH Being released from the pituitary gland and cortisol from the adrenal gland
236
Benzodiazepines
Treatment for anxiety disorders before antidepressants were discovered
Binds to receptor sites for the neurotransmitter GABA which temporally stops a lot of activity in the brain, including ones that are involved in fear and anxiety
Many bad side effects
237
Tricyclic antidepressants (anxiety treatment)

Specifically good for OCD
SSRIs are the best ones
238
Best treatment for specific anxiety disorder
Exposure; Meds only dampen anxiety and make this less effective
239
Treatment of social anxiety disorder
Cognitive-behavioural group therapy (CBGT); same results as Meds with less chance of relapse
D-cyclocerine helps social anxiety
240
Treatment of generalized anxiety disorder
Benzos=good short term but not so much long term , can develop tolerance or dependance
CBT=best results
241
Treatment of OCD
Exposure and ritual prevention (ERP)
Serotonin based Meds
CBT still recommended most of the time
