17

What risk factors are associated with increased likelihood of developing post-trauma problems (not just PTSD)?
For pre-trauma:

1. Childhood trauma
2. Prior psychiatric history
3. Family instability
4. Substance abuse
5. Socioeconomic disadvantage

in other words, they do not have adequate coping resources - less likely to cope in a normative fashion when faced with trauma

18

What risk factors are associated with increased likelihood of developing post-trauma problems (not just PTSD)?
Trauma factors:

1. degree of life threat or loss

2. Severity of exposure to traumatic elements eg grotesque sights, duration (first responders) - more likely to lead to dissociation symptoms, flashbacks

3. Location of trauma (eg an attack in a 'safe' place changes your perception of the world)

4. Individual's role in the trauma (victim, helper)

5. Meaning of trauma (eg uncontrollability)
- eg rape victim who later finds out her rapist was also a serial killer (could have been killed - meaning changes)

19

What risk factors are associated with increased likelihood of developing post-trauma problems (not just PTSD)?
Post-trauma factors:

1. Social support

2. Coping style

3. Ongoing stressors (eg police investigation, injury)

20

What are the biological treatments for PTSD?

Benzodiazepines, SSRIs

21

Do psychological interventions for PTSD work?

Yes, but many people with PTSD simply aren't ready, can't go through with it - so recommended to firstly take medication

22

Core treatment components of CBT for PTSD:

1. assess suitability - people need to be in a focused place to start treatment

2. psychoeducation

3. anxiety management techniques

4. cognitive restructuring

5. prolonged exposure (record event in present tense, in great detail, about an hour - record over and over again)
- and then listen to the recordings at home until it loses its fear value
- then exposure to stimuli, graded

23

CBT is more effective than

medication or supportive psychotherapy (placebo)

24

problems with CBT for PTSD

1. drop-out rates high

2. research conducted in very controlled settings, participants without comorbid conditions - need to test in community setting
