Q

What are the two steps in Mowrer’s 2-stage model of PTSD?

A
  1. PTSD symptoms arise from classical conditioning, but people with PTSD often have elevated tendencies to develop and sustain conditioned fears, due to the severity of the original distressing event
  2. Operant conditioning maintains the negative association - eg. the intrusive/avoidant symptoms reinforce the distress initially experienced

Q

Why is human based trauma often worse for PTSD than natural disasters?

A

Distressing events caused by humans are more likely to cause PTSD than natural disasters probably because of the interpersonal effects it has on people’s rates of trustworthiness / targeted nature of the trauma to oneself

Q

How does task complexity mediate levels of stress and performance?

A

Simple tasks - higher levels of stress arousal are needed for optimal performance

Complex tasks - lower levels of stress arousal are needed for optimal performance due to more cognitive resources being utilised

31
Q

How does type of motor task mediate arousal and performance

A
  1. Some sports are better for low levels of arousal that use precision movements, eg. golf
  2. Sports that use gross motor skills often require higher levels of arousal, eg. football
32
Q

What is the pre-task stress evaluation of the situation in the challenge or threat model?

A

this is a cognitive evaluation of the task happens early stress can be viewed as a threat or a challenge

33
Q

What happens if person perceives stressor as threat and/or challenge?

A
  1. If perceived as a threat - the person may feel overwhelmed and have impaired performance, low resources, high demands
  2. If perceived as a challenge, it is energising and enhances performance, high resources, low demands
34
Q

What is the process of the threat challenge model?

A
  1. Pre-task Stress appraisal (challenge or threat)
  2. Stress reactivity - physiological responses efficient/inefficient responses from SNS
  3. Performance - better or worse
  4. Post-task stress appraisal - coping mechanisms for stress, leading to more or less stress
35
Q

What does the Stress Buffering Model posit?

A

There is a relationship between our resources (eg. social support) + psychological distress + our stressors

36
Q

How do resources influence the relationship between our distress and our stressors?

A

Higher levels of resources can reduce relationship between distress and stressors and has effect on distress independent of stressors

37
Q

What is the biological origin of psychological stress?

A

Limbic system + cerebral cortex

Emotions, cognitions, coping mechanisms, appraisals, arousal and motivations

38
Q

What is the biological origin of physiological stress?

A

Autonomic NS and HPA axis -

Metabolism, immune system, cardiovascular activity, digestion and reproduction

39
Q

What is the biological origin of behavioural stress?

Sympathetic NS

Aggression, running away, freezing, reflexing, facial expressions

40
Q

What’s the difference between primary and secondary appraisals?

A
  1. Primary appraisal - how we evaluate an event/interaction that affects us
  2. Secondary appraisals - evaluating contextual factors to guide our responses
41
Q

What 2 things does cognitive appraisal consist of?

How does it create a cognitive cycle?

A
  1. A stress pre-task evaluation
  2. A stress post task evaluation

the post task evaluation, whether good or bad, creates a cycle that influences the next pre-task evaluation and our behaviour and attitudes

42
Q

When and why does a stress response occur?

A
  1. When appraisal perceive threats, stress reactions occur, in pre-task appraisal (modulating our stress) or in post-task appraisal (after outcome we can feel stressed)
  2. When we perceive it outside our coping ability
43

  2. Planning - thinking about how to cope, strategies, steps, with the stressor when we encounter it
  3. Suppression of competing activities - focusing on the stressor and putting away other projects
  4. Restraint coping - waiting until appropriate opportunity and not acting prematurely
  5. Seeking social support for instrumental reasons - advice, assistance / info
45

  2. Chronic trauma - repeated exposure, eg. ongoing abuse, war zones
  3. Complex trauma - multiple and varied events, often childhood and interpersonal trauma
  4. Secondary (vicarious) - hearing/witnessing an event, common in healthcare first-responders/therapists
54
Q

What do you need to have Emotional adjustment disorder (DSM-5)?

A
  1. Event is seen as distressing but is not traumatic
  2. Clinically significant symptoms where the reaction of the event is out of proportion to the severity of the stressor OR
    Significant impairment in an area of functioning

Reaction to event occurs within 3 months, and then lasts no longer than 6 months

Not meeting a representative of normal bereavement, eg. grief/loss

55
Q

What specifiers are added to emotional adjustment disorder?

A

Specifiers (additional info + disorder) - eg. adjustment disorder + depression, anxiety, conduct disturbance and emotional regulation

56
Q

What do you need to have acute stress disorder?

A
  1. Three days - 1 month
  2. Significant distress and impaired functioning

Intrusive symptoms, eg. nightmares, dissociation, flashbacks, psycho/physio reactions to cues to the event

Negative mood - inability to experience positive emotions

Dissociative symptoms - altered sense of reality, struggle with remembering event

Avoidance symptoms - avoiding memories/reminders of event

Arousal symptoms - sleep difficulty, hypervigilance, irritability, anger,

57
Q

Whats the difference between ASD and PTSD?

A

ASD has broader criteria than PTSD,
+ focus on dissociative symptoms

PTSD lasts more than one month - years, focus on avoidance, changes in cognition and mood

58
Q

What are the two disadvantages of ASD?

A
  1. ASD could stigmatise very common short term reactions to serious traumas, as many report significant symptoms after 1 month of assault
  2. ASD has low predictive validity for those to develop PTSD
59
Q

What is the one advantage of ASD?

A

identifying and treating symptoms of ASD could help prevent PTSD

60
Q

What symptoms do you need in PTSD?

A

Meet at least 1 intrusive symptom: re-experiencing the event, dreams, nightmares, intrusive memories provoked by minor sensory cues, eg. smell, similar resemblance to someone, physical locations

Meet at least 1 avoidant symptom: of stimuli associated with event (often fails)

Meet at least 2 negative mood symptoms: - inability to feel happy feelings, detachment, social withdrawal, distrust of others and the world, self-blame, disordered cognitions

Meet at least 2 arousal and reactivity symptoms - always on guard, monitoring environment, heightened physiological responses to small events, jumpiness, sleep issues, self-destructive behaviour

61
Q

What THREE specifiers are included in PTSD?

*think of what could also occur in severe trauma

A
  1. Depersonalisation - persistent feeling of being detached from ones body and mental processes, dream-like state
  2. Derealisation - persistent experience of unreality of surroundings of outside world seems unreal/dream like
  3. Delayed expression - instance where full diagnostic criteria not met until at least 6 months after the event
62
Q

What are examples of maladaptive appraisals that influence the onset of ASD and PTSD?

A
  1. Self blame thoughts “I was weak so this happened to me”
  2. Individual feelings of hopelessness “I am pathetic I cannot cope”
  3. Environmental feelings of hopelessness “I do not feel safe in this space/with these people”
63
Q

What 2 stress neurotransmitters influence the fear conditioned response?

A

Noradrenaline & adrenaline
- hyperawareness, startle responses, being on edge
“N - A” - “Naaaaaaa!!!”

64
Q

What 3 things is the hyperactive amygdala involved in in PTSD?

A
  1. Fear conditioning: neutral stimuli linked to trauma led to exaggerated responses in PTSD
  2. Emotional memory: emotional dysregulation & memories add to vivid intrusiveness
  3. Hypervigilance: become conditionally related to traumatic event
65
Q

How is the amygdala linked with the hippocampus in PTSD?

A

because the amygdala disrupts contextualisation of memories from hippocampus and regulation of emotions in trauma

66
Q

What 4 things is the diminished hippocampus involved in in PTSD?

A
  1. Disrupts memory encoding and retrieval of trauma
  2. Disrupts emotional regulation
  3. Disrupts contextual processing
  • temporal disruption leads to difficulty distinguishing past/present
  • leads to intrusive recollections and detaches them from original context
  1. Disrupts neuroplasticity
    - neurogenetic and dendritic branching, impacting ability to recover from trauma
67
Q

How is the hippocampus linked with the amgydala?

A

Disrupts interactions with amygdala through its reduced hippocampal volume and function and leds to exacerbating activity in the amygdala

68
Q

What’s the prevalence of adverse childhood experiences in the US?

A

62.5% of US adults have at least one ACE, 25% have at least 3 ACE

69
Q

What 3 effects does ACEs have on a person?

A
  1. damage to neurodevelopment
  2. heightens risk of chronic health problems, eg. chronic obstructive pulmonary disease
  3. heightens risk of health risk behaviours, eg. smoking/drugs
70
Q

When does toxic stress occur?

A

from strong, frequent and prolonged adversarial experiences

71
Q

What’s the critical period of children’s development?

A

around the first 1000 days from birth

72
Q

What 2 things can trauma impact in critical period of child’s development?

A
  1. short term memory
  2. emotional regulation
73
Q

What neurochemicals are linked with poor neurological development in prolonged exposure?

A
  1. cortisol
  2. adrenaline
74
Q

How long does ACEs affect people?

A

People with trauma carry markers of stress, eg. increased cortisol in the brain long after their ACEs occurred, and as trauma varies in duration and intensity for individuals, it resulting in different brain chemistry across individuals

  • often struggle with mood disorders relating to emotional regulation, eg. depression and anxiety
75
Q

Identify and provide examples of one for Specialist Winski:

  1. intrusive symptom
  2. avoidance symptom
A
  1. Intrusive symptom - recalling vivid memories from war, nightmares
  2. Avoidance symptom - avoiding people and social events, reluctance to acknowledge and discuss the duration and severity of symptoms, reluctance to answer questions
76
Q

What are the limitations of diagnostic categories and how they may have impacted Specialist Winski’s resistance to the proposed diagnosis?

A

His reluctance to acknowledge and discuss the duration and severity of symptoms may impact him receiving a diagnosis, even though they are most likely the product of PTSD

77
Q

Explain an alternative framework of psychopathology could be used to discuss Specialist Winski’s symptoms during a clinical interview

A
  1. A cultural framework interview (CFI)
  • CFI provides insight into the clients perspective of their own illness
  • “Language matching” - clinician is encouraged to use the same words as patient to build rapport
  • considers how the cultural context could influence how the patient thinks, feels and interprets their symptoms
  • assess patient’s perceived needs, and if they perceive differences/misunderstandings between them and the clinician
