Results Searches revealed 1459 titles from which 10 experimental studies were included. Five studies were randomised controlled trials (RCTs) and five were pre-post studies. Targeted health conditions were anxiety disorders, weight maintenance, morning sickness, substance misuse, and claustrophobia during MRI scanning. NLP interventions were mainly delivered across 4–20 sessions although three were single session. Eighteen outcomes were reported and the RCT sample sizes ranged from 22 to 106. Four RCTs reported no significant between group differences with the fifth finding in favour of the NLP arm ( F = 8.114, P. INTRODUCTION Neurolingistic programming (NLP) is an emerging technology within health care attracting interest and investment, particularly within primary care.
NLP is a communication framework using techniques to understand and facilitate change in thinking and behaviour. Early study of NLP was of a scholarly nature and promoted NLP as a psychotherapeutic technique, although publication of commercial works, in the 1980s signalled a move between the academic and commercial worlds. While there is no agreed definition of NLP, different formulations share (or practitioners accept) a set of core propositions. In particular, NLP proposes that our internal representations of the world show a bias for a particular sensory modality (visual, auditory, kinaesthetic, olfactory or gustatory), and that a person’s dominant modality, or preferred representational system (PRS), is signalled through various behavioural indices, particularly verbal expression and eye movement. A visual person, for example, may say ‘I see what you mean’ whereas an auditory thinker may say ‘I hear what you say’. The central tenet, or hypothesis of NLP is that communication will be more effective, or persuasive, if it is tailored to match the PRS of the target person.

NLP practitioners use the individual’s PRS as a foundation to the development of rapport, to facilitate modelling, elicit well formed outcomes and use anchoring (or conditioning) techniques. How this fits in Neurolinguistic programming (NLP) is a collection of communication and behaviour change techniques used within the NHS for both clinical and managerial purposes and has a reputation in the business and entertainment industry as a method for influencing people. NLP is promoted to health professionals as a therapeutic and managerial intervention. Limited experimental research has been undertaken into the use of NLP to influence health outcomes and there is little evidence that NLP interventions improve health outcomes based on poor quality studies across heterogeneous conditions and populations. The allocation of NHS resources to support NLP activities should be confined to research investigations. NLP’s position outside mainstream academia has meant that while the evidence base for psychological intervention in both physical and mental health has strengthened, – parallel evidence in relation to NLP has been less evident and has attracted academic criticism., No systematic review of the NLP literature has been undertaken applying Cochrane methods.
The aim of this study was to conduct a systematic literature review and appraise the available evidence for effectiveness of NLP on health-related outcomes. METHOD Studies were eligible for inclusion if they reported primary research on the effects of NLP on any health-related outcomes in all clinical populations.
Studies without a quantitative evaluation of the effect of NLP, single case ( n = 1) studies, and those in which a single NLP technique was evaluated were excluded. Language eligibility was restricted to English.

The following keywords ‘neurolinguistic/neuro-linguistic and neuro linguistic programming’ were combined using the ‘OR’ Boolean operator together with the MeSH heading ‘neurolinguistic programming’ (available for MEDLINE only). Wanda To Kyozou Iso Ps2 Torrent. The specialist NLP databases at the Universities of Bielefeld and Surrey (to 20/02/12), and the European Association for Neuro-linguistic Psychotherapy (to 20/02/12) were also searched in their entirety, and NLP associations, research groups, and social network forums, were contacted for additional research. Reference lists were screened for additional citations.
A single reviewer initially screened all search results by title and those deemed potentially relevant were assessed against the eligibility criteria by two reviewers independently, with discrepancies resolved through discussion. Full-text papers of included studies were assessed against the eligibility criteria by two reviewers independently and discrepancies were resolved through discussion or referral to a third reviewer. A data extraction template was developed, pilot-tested on two papers by three reviewers, and modified as necessary. Two reviewers independently extracted data from each study, including: publication details (authors, year, and country), participant characteristics, intervention details, outcome measures, risk of bias, and study findings. Risk of bias assessment for the randomised controlled trials (RCTs) was undertaken with reference to the Cochrane Handbook. The RCTs were assessed against the four risk domains of sequence generation, allocation concealment, blinding of outcome assessors, and incomplete outcome data. The risk of bias was assessed based on the reported study methods according to the following criteria; low risk of bias = all domains adequately met, high risk of bias = at least one domain not met and uncertain risk of bias = inadequate reporting of methods.
Risk of bias for the pre-post studies was assessed using the Downs & Black quality index score. This is a validated checklist for assessing the quality of randomised and non-randomised studies in five subscales: reporting, external validity, internal validity (bias and confounding), and power. Available evidence A total of 1459 citations were retrieved using the search strategy. Of these, 93 titles were potentially relevant (). Abstracts were obtained and screened and 41 full text papers reviewed.
Of the initial 93 citations, the majority were excluded as they were descriptive in nature, were not NLP interventions or they involved only healthy populations. In total, 10 studies were identified meeting the inclusion criteria (). Due to the small number of studies identified and heterogeneity (in research design, populations, NLP interventions, and assessed outcomes), statistical analysis was not appropriate and a narrative synthesis of the evidence was undertaken. Nine studies were published in peer-reviewed journals and one was identified online. Characteristics of included studies Five studies were randomised controlled trials (RCTs) – and five were observational/ pre-post test studies. – These were conducted in the US, Denmark, UK, Croatia, Brazil, and New Zealand.
Targeted health conditions include various anxiety disorders, weight maintenance, morning sickness, substance misuse, and claustrophobia during MRI. The five RCTs targeted anxiety disorders, maternal anxiety/child development and weight maintenance. Two used NLP interventions versus a no-intervention control arm and three compared NLP to an active intervention.
Within the five RCTs, follow-up occurred immediately following a single session treatment, at 1 month, 5 months, 9 months and 3 years. Within the 10 included studies participants were recruited broadly from childcare, criminal justice, and public and private healthcare facilities, higher education and the press. Demographic data about participants was poorly reported with eight studies reporting some data on sex.
Two of these studies specifically recruited women only and the six remaining reported data indicating that overall 64% of study participants were female. Six studies reported participant age, albeit inexactly, with a range from 17–75 years and a mid-range estimate of approximately 40 years. One of the RCTs presented broader socioeconomic data and found participants to be college educated or higher (100%), married (24%), and employed (56%). Interventions Delivery of NLP interventions ranged from three studies using a single 1–2 hour session,, to the remainder offering 4–20 1–2 hour sessions. Duration of intervention was reported by six studies ranging from 4 weeks, 21 days residential, 4–5 months, and 12 months. One study offered group NLP.
Six studies described the qualifications and training of the interventionists and these included three clinical psychologists, eight psychotherapists,, a certified NLP practitioner, and an NLP practitioner level radiographer. These NLP interventionists were all certified to a minimum of NLP practitioner level with two stated as being master practitioner certified., The interventionist training level was better described in the RCTs.
Intervention techniques reported were mixed with six studies,, – employing a well-established NLP intervention described in the NLP literature., Four studies referred generally to ‘NLP techniques’ or ‘NLP behaviour modification’. The observational studies provided greater detail about the interventions employed.
Outcomes Across the 10 studies, 23 measures were used, and 18 outcomes reported. Outcomes were largely aligned to the targeted condition and the most common outcome assessed was anxiety, –, with three also measuring quality of life and depression., Validated measures were referenced by seven studies with a further two reporting the outcome was assessed but not how.
All psychological outcome measures were different across these eight studies. Only three studies measured objective outcomes, weight, successful completion of MRI scan, and urinalysis for illegal substances.
Of the 18 outcomes reported, 11 were self-reported, three were objective measures, two were observed, and two not reported. The two observed measures were from RCTs, and one had a blinded outcome assessor and the other was unclear. In general the RCTs performed no better than the pre-post studies in terms of reporting of outcomes and the process of their measurement. Download Software Penjualan Tiket Online. Risk of bias In three of the RCTs, the risk of bias was high with alternate group allocation,, and incomplete outcome data reporting (). In two RCTs the risk of bias was uncertain., None reported results by intention to treat (ITT) analysis and, although one reported undertaking ITT analysis, only the completer analysis was presented. Three RCTs fared better in reporting withdrawals and participants lost to follow-up. In the pre-post study designs, the quality index scores ranged from 6–13 (maximum rating is 23 for non RCTs) where low ratings represent poor quality.
Only one paper scored above the scale mid-point for quality. NLP effects Across the five RCTs, NLP was evaluated with undergraduate students, mother and child pairs, weight challenged adults, and emotionally-distressed adults for which the main outcomes were assessed ranging from immediately post-treatment to 3-year follow-up. Main outcomes reported were anxiety (self-report), child development (observed), weight (objective), and quality of life (self-report). Four RCTs reported no significant between group differences in the assessed outcomes with the fifth reporting less psychological distress and increased perceived quality of life in the NLP group compared to the waiting list control arm.
Three RCTs and five pre-post studies reported within group improvements. Of the three studies measuring objective outcomes, one reported a post-treatment increase in completed MRI scans and the other two reported no post-treatment improvement in urinalysis for illegal substances or weight maintenance. Strengths and limitations This represents the first well-conducted review investigating the effectiveness of NLP on health-related outcomes. The study has not attempted to define NLP and its many components and techniques and this complicates the interpretation of the evidence. This study took the authors’ word that they were delivering NLP if they said they were and the evidence of levels of training of the interventionist supported this assumption.
Some academic investigation into NLP was found in unpublished German language dissertations that the library advised would not be possible to obtain and this represents a possible gap in the evidence. The decision was taken to exclude studies using single NLP techniques. NLP has a lack of consensus surrounding a definition of techniques and mechanism of effect and on an individual technique basis there is overlap with more established and evidence-based psychological techniques. Arguably these could include developing rapport = person-centred counselling; modelling = vicarious learning; eliciting well formed outcomes = goal setting; reframing = cognitive behavioural therapy (CBT) techniques; and anchoring = classical conditioning. Inclusion of studies labelled by their authors as NLP and focusing on one of these single NLP techniques would have lead to a misleading observation of the evidence. Publication bias assessment was not formally calculated because only 10 studies were included.
The scoping reviews around the practice of NLP in physical and mental health conditions suggested it remains a controversial intervention. As only one of the five RCTs showing a positive effect in favour of NLP was found, the authors are less concerned about publication bias.
However, it is possible that the controversy surrounding NLP may lead to a publication bias against studies that find a positive effect in favour of NLP. Risk of bias in the five RCTs was high, or uncertain due to inadequate reporting of methods. It was not possible to determine the risk of bias associated with selective outcome reporting due to the absence of published study protocols.
Assessment of the pre-post studies found four scoring lower than the scale midpoint score indicating a high risk of bias. Implications for research and practice There is currently insufficient evidence to recommend use of NLP for any individual health outcome.
Neither this review, nor the FOI NHS trust data, point strongly to appropriate populations for further research. Use of NLP in specific settings may be vindicated in future, and preliminary data from its use in MRI/claustrophobia may justify a sufficiently powered RCT to clarify its role for these patients.
Discussions with NLP key informants identified populations, for example allergy sufferers, who they felt were a strong target population for further NLP-based research. A formal stakeholder consultation with a range of NLP master practitioners would be an important next step for identifying such target populations for research.
The strength of evidence for CBT would suggest it as a possible comparison group. The risk of bias assessments point to the need to develop a fully-specified and replicable intervention protocol for evaluation in a sufficiently powered RCT.
