transdiagnostic approach Flashcards
limitations of disorder based therapies
- There are dozens of different disorders in the population
- Are we really going to train therapists different models for different psychiatric disorders?
- Average no. sessions attended is around five (Hansen et al. 2002)
- Greatest treatment gains in the first session (Lambert et al. 2001)
- 30-80% of patients have comorbid disorders
- Standardised diagnosis is not conducted (c.90mins)
Therefore we need a universal flexible therapy that can be started early on
is classification valid but not always useful?
yes it is efficient but not necessry for treatment in psychology
key factors are shared across disorders
distress irrespective of any particular diagnostic category
Pivotal papers: e.g. Ingram (1990); Persons (1991); Hayes et al. (1996)
‘Transdiagnostic’ CBT for Eating Disorders (Fairburn, Shafran & Cooper, 2003)
Biology (e.g. COMT gene) - OCD, schizophrenia, bipolar disorder, anorexia nervosa, phobias
Social Factors (e.g. Expressed Emotion) : Schizophrenia, mood disorders, anxiety disorders, eating disorders
So, what is the evidence that the ‘mechanisms’ maintaining disorders might be shared?
what are the criteria for transdiagnostic processes
Criteria for a transdiagnostic process
Strong methodology (e.g. valid measure; control group)
Present in ALL disorders & over 4 disorders
what are the advantages of transdiagnosti approaches
generalise models across disorders
understand comorbidity
inform transdiagnostic treatments
what are the transdiagnostic processes
attention reasoning behaviours memory thinking
what is attention
Hypervigilance to external threat
Attentional avoidance of external threat
Hypervigilance to internal experiences
what is memory
Recurrent intrusive memories
Selective memory
(Overgeneral memory)
reasoning
Interpretational bias
Expectancy bias
Emotional reasoning
thinking
Recurrent negative thinking
Metacognitive beliefs
(Thought suppression)
behaviours
Avoidance
Safety-seeking behaviours
Experiential Avoidance
what are the core processes
Anxiety , depression Standardised measures of thought suppression, worry & experiential avoidance
r = .5 to .7
Separate processes vs core process in predicting distress in students & in chronic physical illness
worry thought suppression and experiential avoidance
What does psychological distress and recovery involve?
- Qualitative Interviews & Analysis
- Themes of loss of control at the ‘rock bottom’ & regaining control as the process of recovery •Fits with wider literature
- Natural recovery across disorders (Higginson & Mansell, 2008)
- Primary care service (McEvoy et al., 2012)
- Bipolar disorder (Mansell et al., 2010)
- Eating problems (Alsawy & Mansell, 2013)
- Use of art in recovery (Stevenson-Taylor & Mansell, 2012)
what is control and why is it important
- Homeostasis is control; this is essential for life
- Now: temperature; balance; blood sugar
- Co-ordination & movement for any activity relies on control
The historical context of Perceptual Control Theory
- Fits with the teleological approach of early psychology (e.g. William James, John Dewey)
- Fits with importance of unconscious conlict (Freud, Horney)
- Powers was a control system engineer who developed the theory through the 1950s & 60s
- Encountered cybernetics (e.g. Wiener; Ashby)
- Inluenced William Glasser’s Reality Therapy; Klaus Grawe’s Psychological Therapy; now inluencing the development of CBT (Mansell, 2005)
