A Need for Research in NLP and its relevance to health-care
 
By Henrie Lidiard

If the benefits of NLP are to be taken more seriously in the realm of health care, I believe our relatively young and rapidly expanding discipline needs to be researched in a credible way. 
 
1. A difference of world-view!
The collective world-views of the medical and NLP communities are very different. Consequently the strategies that the two communities use for becoming convinced are also somewhat different. In the medical world there is a need for due authority, analysis, peer reviewed journal publications, science, facts, data and proof derived from credible controlled studies. Whereas in the NLP community many people feel that subjective evidence is sufficient. There is also a segment of the NLP community that can appear ‘new-age’ ‘anti- science’ and imprecise in its claims for the discipline (e.g. simply think positively and you’ll be well).
 
Given the contrasting world views there are a number of counts where NLP may be perceived as needing to prove itself from within a medical mind-set:
 
  • Firstly our discipline is a young ‘upstart’ in comparison to many forms of therapeutic approach.
  • Secondly, knowledge of NLP is in the public domain and not simply in the possession of highly trained experts. (hence raising potential concerns about the lack of quality control, supervision and consistency)
  • The claims made for the efficacy of NLP are backed up by very scant research and such research as exists is of mixed quality and validity. It may also be presented with little relevance to health-care professionals.
 
 
2. Existing research (and not much of it!)
An excellent summary by R.Bolstad (1997) lists several research studies of NLP that are of relevance to Health-care. There are also a number of additional studies since his 1997 review. I can’t help noticing that there is a strange concentration in the research on a few small areas of NLP (e.g. the existence of primary representation systems or the use of predicates) rather than a wider examination of the results of the more therapeutic interventions. The notable exception to this being a relatively large number of studies on the VK Double dissociation Trauma cure.   The list that follows adds a few additional papers to Richard’s summary.
 
REP systems
Dilts and Epstein (1995) conducted a study on eye movements/ Rep systems and found measurable differences in performance in spelling when different Rep systems/eye positions were used. Falzett 1981 and Hernandez 1981 both provide evidence that supports the eye-accessing cue model as described by NLP. (Although Hernandez didn’t find data to support kinaesthetic related eye movements)
 
Predicates
Falzett (1981), Yapko (1981a and b, House 1994), All concluded in various ways and with various emphases that using a person’s preferred sensory predicates in communication with them deepens trust, rapport and measurable levels of trance and relaxation.  
 
Submodalities
Buckalew and Ross (1981) studied the effect of placebos according to colour and size. Smith and Laird (1930) reported that sound volume has measurable physical effects on stomach contraction.
 
Unconscious mind
One of the clearest piece of evidence for the existence of the unconscious mind and our ability to communicate with it is in the study of Cheek (1981) who induced 3000 fully anaesthetised patients to produce hand signals for yes and no without their conscious knowledge. There are also excellent case examples of the practical use and effect of Milton Erickson’s language patterns in the emergency Room by Bierman (1987).
 
VK double-dissociationTrauma-Cure
Denholtz and Mann (1975), Koziey and McLeod (1987), Einspruch (1988), Muss (1991), Hossack and Bentall (1996) all published small scale case-based trials of the trauma cure having achieved significant success with the process. In addition Dietrich et al (200) compare the trauma cure to other ‘alternative’ methods of working with post-traumatic stress disorder and conclude that it is an effective method. Dietrich (2000) also postulates reasons why this technique may work. It is also worth noting that there are some procedural variations in the versions of the trauma cure which are tested.
 
Anchoring
Davison and Neale (1986) published and article about inducing and removing a phobia using anchoring. Langer (1989) described a study of the incredible physical and psychological benefits of anchoring in working with the elderly.
 
Anxiety and depression
There are also a number of studies which describe how anxiety and depression have been alleviated using NLP, e.g. Koziey and McCleod (1987), Einspruch (1988), Konefal et al. (1992) Hossack and Standidge (1993) and case examples are also described by Rushworth (1994).
 

3. Credibility and validity of research
This is a challenging area on two counts: 
 
  • Firstly because some studies designed to test NLP haven’t built in considerations of validity, sample bias, comparisons to placebo/control groups, effect size and duration of effect. (Dietrich et al. 2000)
  • And secondly because some of the research studies designed from a more ‘scientific’ point of view have done so from a corresponding position of ignorance of NLP principles and what effective NLP practice involves. (Einspruch and Forman 1985)
Whilst we may need credible research that examines the different aspects of NLP, it is important to recognise that much of the power of the NLP approach lies in the synthesis of a particular set of ideas and practical tools and what can happen when they are used together systematically.
 
We need, in effect, individuals and/or research teams that have both high levels of skill and awareness in using NLP and corresponding levels of skill and experience in designing research that can stand up to critical scrutiny. 
 
We have been fortunate to have such a team working together in Ellesmere Port on the Living with Cancer project(Directed by Carolyn Temple and described in more detail by Nancy Moss, Carolyn Temple and Miranda Thurston: Special Iissue of NLP News March 2005.) The results of this important and ground-breaking qualitative research are summarised in this issue and can be read in full in Sargent et al. (2004)
 
I believe there is also a need for published accounts from medically-trained health professionals about the results they are achieving using NLP in their practice.
