Chapter 15 Flashcards
Anxiety
- Specific phobias
- Social anxiety disorder
- Generalized anxiety disorder
- PTSD
- Panic disorder (with and without agoraphobia)
- Most effective treatment is Exposure Therapy
and Cognitive Behavioural Therapy
Exposure
Approaches
Used to change behaviours involving fear
and anxiety
* Imaginal or in vivo
* Graduated or intense
* Spaced out sessions or en masse
* One session or multiple sessions
Exposure
Techniques
Common element: client is exposed to
anxiety-eliciting stimuli without
experiencing the feared negative
consequences
Treatment includes:
Modification of the operant
escape and avoidance
behaviours
Modification of the
respondent behaviours (the
Conditioned Responses)
Avoidance
Diagram
2 parts: Escape + Avoidance
- Escape – removal of negative reinforcer
- Avoidance – prevention of further
negative reinforcers
Maintains the cycle
* HARD to extinguish because of
intermittent reinforcement
Exposure
Interventions
Systematic Desensitization
In Vivo Desensitization (Exposure)
Prolonged Exposure (PE) Therapy
Virtual Reality Exposure Therapy (VRET)
Eye Movement Desensitization Reprocessing (EMDR)
Exposure and Response Prevention (ERP)
Systematic
Desensitization
Techniques
* Imaginal exposure (generalizes to real life)
* Decrease phobic responses
* Using a graduated hierarchy of feared stimuli
* Relaxation Techniques
* Don’t focus on what US initially created the fear (UR), but on
what is maintaining the CRs now
Three steps:
* Relaxation Training
* Construction of anxiety hierarchies
* Pair the relaxation + phobic stimuli until phobic stimuli no
longer elicits anxious symptoms
In Vivo
Desensitization
(Exposure)
Similar to Systematic Desensitization → extinction of the
anxiety and avoidance response
* Except uses real-life situations (not just imagined)
- Remain in the presence of the feared stimulus for brief
periods of time → longer and longer time - Don’t need to worry about generalization because it’s already
happening in the real-life already - Phobia Treatment:
- Anxiety CRs are extinguished by repeated presentation of
the conditioned stimulus (CS) in the absence of the US. - The operant avoidance response also extinguishes
because of the removal of the negative reinforcement
contingency established previously.
Prolonged Exposure Therapy
- Rather than graduated exposure, this is at fullintensity for a prolonged approach (either
imagined or in vivo) - Flooding – sometimes even 1 session
- Prevent any escape or avoidance from the
feared stimulus - Absence of feared consequences
- Develop a tolerance for the anxiety
- Associate the feared stimulus with being safe
- Panic disorder – this is an essential aspect of
treatment - PTSD – equivocal (not enough RCTs)
Virtual Reality
Exposure Therapy
(VRET)
- Computer-generated exposure
environment - Visual, auditory, and olfactory
stimuli - Effective in PTSD * Augmented reality
– enhances
aspects of the “real
-world” - Good for specific phobias (e.g.,
spider) - Generalizable??
Eye movement
Desensitization
Reprocessing (EMDR)
- Imaginal exposure of a stressful/traumatic event (PTSD)
- Performing rapid eye movements back-and-forth
Controversial whether the eye moments add to the effectiveness, or if
the cognitive processing part is the key element.
* Other treatments:
* Cognitive Processing Therapy (CPT) - https://www.apa.org/ptsdguideline/treatments/cognitive-processing-therapy
* Trauma-Focused CBT -
Exposure and Response
Prevention (ERP)
Often used in OCD
* Obsessions – repetitive, unwanted
thoughts or images
* Compulsions – repetitive, excessive overt
acts or responses that have negative
consequences for them or others
- Two components:
- In vivo exposure
- Strict response prevention
- Efficacy rates high (75-85%), but high dropout
rates (20-30%) - Similar outcomes to medication alone
- Helpful if you can involve social support
Habit
Reversal
Training
From Chapter 4:
1. Awareness Training – detect pre-urge signs
2. Competing Response Training
* Blocks the behaviour over the duration of
time (fixed/variable)
3. Motivational and Social Support
* Behavioural Reward System,
Parent/Peer/Teacher praise
Comprehensive behavioural intervention for tics (CBIT)
Dr. Ali Mattu
Aversion Therapy
- Used to treat behavioural excesses
- Aversive stimulus is presented with the stimulus to
prevent the undesired response - Enhances escape/avoidance behaviours through
negative reinforcement - Not used frequently, ethical concerns, complex
intervention - Requires extra supervision and monitoring, explicitly
discourages in the College of Psychologists of Ontario
(CPO). - More emphasis on the use of positive reinforcement
currently
Cognitive Behavioural
Therapies
(CBT)
- Rational Emotive Behaviour
Therapy (REBT) - Cognitive Behavioural
Therapy (CBT) - Family-Based Cognitive
Behavioural Therapy (CBFT) - Panic Control Treatment
(PCT) - Behavioural Activation
Therapy
Cognitive biases
*Most powerful, hardest to change,
and most likely to be in our moment-to-moment awareness
Perceptions
selective attention
attributions
expectancies
assumptions
standards
Cognitive
Distortions
arbitrary inference
selective abstractions
overgeneralization
magnification/minimization
personalization
dichotomous thinking
labeling/mislabeling
tunnel vision
biased explanations
mind reading
Rational Emotive Behaviour
Therapy (REBT)
Albert Ellis (1961): Rational-Emotive Therapy (RET)
* Problems (anxiety, depression, anger, guilt) occur when individuals:
* Hold irrational or dysfunctional beliefs
* Make negative evaluations and interpretations of self or others because of these beliefs
* Negative cognitive processes (irrational thought patterns) → strong negative emotions (distress)
→behave in negative ways toward self or others
- Irrational beliefs:
- Identify
- Challenge
- Change these irrational beliefs by use of rational argument → “rational beliefs”
- Added “behaviour” to the name to emphasize changing overt behaviour through behavioural
assignments/homework (*key component)
