- Relatively little interest from NICE (Khele, 2008).
[Do they work?]
Rosenzweig (1936): common rather than specific factors
- the Dodo Bird conjecture.
Many meta-analyses (e.g. Wampold, 2006): all therapies lead to comparable effect sizes
– the Dodo Bird effect.
[Common factors research]
‘Common Factors’ most frequently studied: accurate empathy, positive regard, congruence or genuineness
(Lambert & Bergin, 1994)
Preference for ‘gold-standard’ evidence (RCTs) for therapies to be classed as Evidence Based Treatments (EBTs) (see Lecture 5):–Based on Medical Model.–Suited to therapies adopting DSM categories, and using specific techniques to treat symptoms.
HEP's
reject medical model
avoid use of DSM
rely on few 'set' techniques
treat person not symptoms
King et al (2000) – RCT
Mild – moderate depression
PCT and CBT equally effective in reducing depressive symptoms at 4 months – both better than GP care.
However – no difference between 3 groups at 12 months.
Patients in PCT group more satisfied with treatment at 12 months.
Gibbard and Hanley (2008) – Primary Care
PCT effective for anxiety and depression (over 5 years).
NOT limited to mild/moderate – also moderate/severe.
Counselling included as option of first-line treatment for new episodes of less- and more-severe depression
BUT, considered less-well supported than many other options (weighing up clinical evidence and cost effectiveness).
McArthur et al (2013)
School-Based Humanistic Counselling (SBHC) vs waiting list control.
SBHC: Non-directive, based on work of Rogers.
Assumes that distress is brought about by acting in accordance with extrinsic demands rather than intrinsic authentic needs.
