Comparing the effectiveness of an enhanced MOtiVational intErviewing InTervention (MOVE IT) with usual care for reducing cardiovascular risk in high risk subjects: study protocol for a randomised controlled trial. Trials 2015; 16:112. [PMID: 25886569 PMCID: PMC4399238 DOI: 10.1186/s13063-015-0593-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Accepted: 02/06/2015] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Interventions targeting multiple risk factors for cardiovascular disease (CVD), including poor diet and physical inactivity, are more effective than interventions targeting a single risk factor. A motivational interviewing (MI) intervention can provide modest dietary improvements and physical activity increases, while adding cognitive behaviour therapy (CBT) skills may enhance the effects of MI. We designed a randomised controlled trial (RCT) to examine whether specific behaviour change techniques integrating MI and CBT result in favourable changes in weight and physical activity in those at high risk of CVD. A group and individual intervention will be compared to usual care. A group intervention offers potential benefits from social support and may be more cost effective. METHODS/DESIGN Individuals aged between 40 and 74 years in 11 South London Clinical Commissioning Groups who are at high risk of developing CVD (≥20%) in the next 10 years will be recruited. A sample of 1,704 participants will be randomised to receive the enhanced MI intervention, delivered by trained healthy lifestyle facilitators (HLFs), in group or individual formats, in 10 sessions (plus an introductory session) over one year, or usual care. Randomisation will be conducted by King's College London Clinical Trials Unit and researchers collecting outcome data will be blinded to treatment allocation. At 12-month and 24-month follow-up assessments, primary outcomes will be change in weight and physical activity (average steps per day). Secondary outcomes include changes in low-density lipoprotein cholesterol and CVD risk score. Incidence of CVD events since baseline will be recorded. A process evaluation will be conducted to evaluate factors which impact on delivery, adherence and outcome. An economic evaluation will estimate relative cost-effectiveness of each type of intervention delivery. DISCUSSION This RCT assesses the effectiveness of a healthy lifestyle intervention for people at high risk of CVD. Benefits of the study include the ethnic and socioeconomic diversity of the study population and that, via social support within the group setting and long-term follow-up period, the intervention offers the potential to support maintenance of a healthy lifestyle. TRIAL REGISTRATION This trial is registered with the ISRCTN registry (identifier: ISRCTN84864870, registered 15 May 2012).

Abstract
AIMS Increased expectations for the use of evidence-based methods in addiction treatment have fueled a debate regarding the relative importance of 'specific' versus 'common' factors in treatment outcome. This review explores the influence of these factors on addiction treatment outcome. METHODS The authors review and link findings from four decades of research on specific and general factors in addiction treatment outcome research. FINDINGS Although few would argue that what one does in addiction treatment is immaterial, outcome studies tend to find small to no difference when specific treatment methods are compared with each other or with treatment as usual. In contrast, there are usually substantial differences among therapists in client outcomes, and relational factors such as therapist empathy and therapeutic alliance can be significant determinants of addiction treatment outcome. CONCLUSIONS In addiction treatment, relational factors such as empathy, which are often described as common, non-specific factors, should not be dismissed as 'common' because they vary substantially across providers and it is unclear how common they actually are. Similarly they should not be relegated to 'non-specific' status, because such important relational influences can be specified and incorporated into clinical research and training.

Combining intensive practice nurse counselling or brief general practitioner advice with varenicline for smoking cessation in primary care: study protocol of a pragmatic randomized controlled trial. Contemp Clin Trials 2015; 41:298-312. [PMID: 25657051 DOI: 10.1016/j.cct.2015.01.017] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2014] [Revised: 01/23/2015] [Accepted: 01/24/2015] [Indexed: 12/20/2022]
Abstract
INTRODUCTION Combining behavioural support and pharmacotherapy is most effective for smoking cessation and recommended in clinical guidelines. Despite that smoking cessation assistance from the general practitioner can be effective, dissemination of clinical practice guidelines and efforts on upskilling has not lead to the routine provision of smoking cessation advice among general practitioners. Intensive counselling from the practice nurse could contribute to better smoking cessation rates in primary care. However, the effectiveness of intensive counselling from a practice nurse versus usual care from a general practitioner in combination with varenicline is still unknown. MATERIALS AND METHODS A pragmatic randomized controlled trial was conducted comparing: (a) intensive individual counselling delivered by a practice nurse and (b) brief advice delivered by a general practitioner; both groups received 12-weeks of open-label varenicline. A minimum of 272 adult daily smoking participants were recruited and treated in their routine primary care setting. The primary outcome was defined as prolonged abstinence from weeks 9 to 26, biochemically validated by exhaled carbon monoxide. Data was analysed blinded according to the intention-to-treat principle and participants with missing data on their smoking status at follow-up were counted as smokers. Secondary outcomes included: one-year prolonged abstinence, short-term incremental cost-effectiveness, medication adherence, and baseline predictors of successful smoking cessation. DISCUSSION This trial is the first to provide scientific evidence on the effectiveness, cost-effectiveness, and potential mechanisms of action of intensive practice nurse counselling combined with varenicline under real-life conditions. This paper explains the methodology of the trial and discusses the pragmatic and/or explanatory design aspects. TRIAL REGISTRATION Dutch Trial Register NTR3067.

Abstract
OBJECTIVE The English 'stop smoking services' provide behavioural support to some 700,000 smokers annually. Success rates of the services varied considerably before 2010 and had been in slight decline so, to improve performance, a national programme of evidence-based practitioner training was developed to improve knowledge and skills-based competences. This study evaluated whether uptake of the training was associated with improvements in success rates of services. METHODS Mean 4-week biochemically verified abstinence rates were compared for 146 (of 151) stop smoking services between 2008-10 (before roll-out of training) and 2011-13 (after roll-out), and the change in success rates for each service was regressed on to the number of practitioners per service trained in a) knowledge (online) and b) skills (face-to-face). RESULTS Success rate across all services improved between the two periods (34.1% to 36.5%, p=0.01 1-tailed; 95% CI for difference 0.44-4.48). The magnitude of improvement for each service was associated with the number of practitioners who completed the knowledge and skills training (beta=0.22, p=0.005 1-tailed), and marginally with the number who completed the knowledge training (beta=0.14, p=0.047 1-tailed). CONCLUSION English stop smoking services that have greater uptake of a national evidence-based training programme showed greater improvements in success rates.

Abstract
BACKGROUND Psoriasis is associated with unhealthy lifestyle behaviours which contribute to psoriasis onset and severity. Health professionals who manage patients with psoriasis are well placed to support lifestyle change but few feel confident to do so. Little is known about the extent to which health promotion and lifestyle behaviour change (LBC) skills are included within post-qualification training curricula. OBJECTIVES This study aimed to systematically examine the content of post-qualification U.K. training curricula for health professionals across General Practice and Dermatology for evidence of behaviour change skills relating to the promotion of healthy lifestyles. METHODS Core curricula documents from professional organizations were analysed for content to examine the extent to which curricula: (1) mentioned health promotion and LBC as part of the professional role; and/or (2) included health promotion and LBC as explicit training competencies or requirements for qualification. RESULTS Of the 11 core curricula documents analysed, we found 67 occurrences of terms related to LBC and health promotion. Most were in the General Practitioner curriculum (n = 42; 62·7%), followed by the Dermatology Specialist Nurse curriculum (n = 14; 20·9%) and Dermatologist curriculum (n = 11; 16·4%). No occurrences were found in the General Practitioner with a Special Interest in Dermatology curriculum. LBC knowledge, skills and attitudes were not clearly specified and only basic level LBC competencies were included. CONCLUSIONS Development of post-qualification curricula would ensure health professionals are equipped with the necessary knowledge, skills and attitudes to support LBC for patients with psoriasis. This is of particular relevance, given the evidence linking unhealthy lifestyles with psoriasis outcomes.

Abstract
OBJECTIVES Behaviour change technique (BCT) Taxonomy v1 is a hierarchically grouped, consensus-based taxonomy of 93 BCTs for reporting intervention content. To enhance the use and understanding of BCTs, the aims of the present study were to (1) quantitatively examine the 'bottom-up' hierarchical structure of Taxonomy v1, (2) identify whether BCTs can be reliably mapped to theoretical domains using a 'top-down' theoretically driven approach, and (3) identify any overlap between the 'bottom-up' and 'top-down' groupings. METHODS AND DESIGN The 'bottom-up' structure was examined for higher-order groupings using a dendrogram derived from hierarchical cluster analysis. For the theory-based 'top-down' structure, 18 experts sorted BCTs into 14 theoretical domains. Discriminant Content Validity was used to identify groupings, and chi-square tests and Pearson's residuals were used to examine the overlap between groupings. RESULTS Behaviour change techniques relating to 'Reward and Punishment' and 'Cues and Cue Responses' were perceived as markedly different to other BCTs. Fifty-nine of the BCTs were reliably allocated to 12 of the 14 theoretical domains; 47 were significant and 12 were of borderline significance. Thirty-four of 208 'bottom-up' × 'top-down' pairings showed greater overlap than expected by chance. However, only six combinations achieved satisfactory evidence of similarity. CONCLUSIONS The moderate overlap between the groupings indicates some tendency to implicitly conceptualize BCTs in terms of the same theoretical domains. Understanding the nature of the overlap will aid the conceptualization of BCTs in terms of theory and application. Further research into different methods of developing a hierarchical taxonomic structure of BCTs for international, interdisciplinary work is now required. Statement of contribution What is already known on this subject? Behaviour change interventions are effective in improving health care and health outcomes. The 'active' components of these interventions are behaviour change techniques and over 93 have been identified. Taxonomies of behaviour change techniques require structure to enable potential applications. What does this study add? This study identifies groups of BCTs to aid the recall of BCTs for intervention coding and design. It compares two methods of grouping--'bottom-up' and theory-based 'top-down'--and finds a moderate overlap. Building on identified BCT groups, it examines relationships between theoretical domains and BCTs.

Abstract
OBJECTIVES Studies suggest that intraosseous (IO) access is underutilized in adult resuscitations, despite recommendations from advanced trauma and cardiac life support guidelines. The objective was to determine factors associated with IO access use by physicians during adult resuscitations when intravenous (IV) access is not immediately achievable. METHODS This study was an online survey among physicians purposefully recruited from various clinical care areas at three teaching hospitals. Questions were generated from the qualitative results of 20 iterative interviews, verified for internal validity, and piloted. The interview guide was based on the constructs of the Theory of Planned Behavior (TPB), which elicits salient attitudes, social influences, and control beliefs that potentially influence intention to use IO access. Recruitment took place in September 2012 until reaching more than 100% of the required sample size (n = 200). Internal consistency was measured using Cronbach's alpha, and the effect of TPB constructs and specific beliefs were assessed with regression analyses. RESULTS For the 205 respondents, the mean age was 35 years (range = 20 to 66 years), and 53.3% were male. Participants' departmental affiliations were 50.3% emergency medicine (EM), 16.9% internal medicine, 14.9% anesthesia, 10.8% general surgery, and 7.2% critical care. Residents comprised 60.7% of the sample, and 39.3% were attending physicians. Median intention to use IO access when IV is not immediately achievable was 4.67 (interquartile range [IQR] = 4 to 5) out of 5 (5 highest) and predicted by the following TPB constructs: attitudes (AdjCoefficients = 0.504; 95% confidence interval [CI] = 0.334 to 0.673), social influences (AdjCoefficients = 0.285; 95% CI = 0.172 to 0.398), and control beliefs (AdjCoefficients 0.217; 95% CI = 0.113 to 0.320). Physicians were more likely to use IO access if they believed that it provided rapid vascular access for delivering large volumes of fluids, could prevent delays in care, and was associated with a low complication rate. Conversely, the perception that nurses are not familiar or supportive of IO access and a lack of physician confidence regarding the appropriate indications for IO access were barriers to use. CONCLUSIONS These data are an important step in the knowledge-to-action process, as they identify specific factors associated with physician use of IO access. Interventions addressing these actionable facilitators and barriers are likely to have a positive effect on increasing the appropriate physician use of this potentially life-saving technique in adult patients requiring emergent vascular access.

Abstract
PURPOSE The purpose of this study was to identify the behaviour change techniques (BCTs) that are associated with greater effectiveness in smoking cessation interventions for people with chronic obstructive pulmonary disease (COPD). METHODS A systematic review and meta-analysis was conducted. Web of Knowledge, CINAHL, EMBASE, PsycINFO, and MEDLINE were searched from the earliest date available to December 2012. Data were extracted and weighted average effect sizes calculated; BCTs used were coded according to an existing smoking cessation-specific BCT taxonomy. RESULTS Seventeen randomized controlled trials (RCTs) were identified that involved a total sample of 7446 people with COPD. The sample-weighted mean quit rate for all RCTs was 13.19%, and the overall sample-weighted effect size was d+ = 0.33. Thirty-seven BCTs were each used in at least three interventions. Four techniques were associated with significantly larger effect sizes: Facilitate action planning/develop treatment plan, Prompt self-recording, Advise on methods of weight control, and Advise on/facilitate use of social support. Three new COPD-specific BCTs were identified, and Linking COPD and smoking was found to result in significantly larger effect sizes. CONCLUSIONS Smoking cessation interventions aimed at people with COPD appear to benefit from using techniques focussed on forming detailed plans and self-monitoring. Additional RCTs that use standardized reporting of intervention components and BCTs would be valuable to corroborate findings from the present meta-analysis.

Abstract
Little is known about the use of lapse prevention strategies to help smokers manage situation-triggered urges to smoke. Pregnant smokers (N = 174) participating in an intervention trial reported use of cognitive-behavioural lapse prevention strategies and smoking abstinence (biochemically verified). Participants typically enacted few strategies. Distraction strategies were most commonly used. Total number of strategies used did not predict abstinence. However, using 'self-talk' (odds ratio (OR) = 3.44, 95% confidence interval = 1.14-10.40) or 'avoiding spending time with other smokers' (OR = 4.01, 95% confidence interval = 1.34-11.95) independently increased the odds of abstinence. The promotion of these and other under-utilised evidence-based strategies warrants further attention.

Abstract
BACKGROUND Disadvantaged smokers are less likely to be successful when trying to stop smoking than more affluent smokers. In the UK, NHS Stop Smoking Services (SSS) provide a range of pharmacotherapy and behavioural support, delivered by advisors with a range of backgrounds. Whether the types of support provided and who provides it influence differences in quit rates amongst low SES smokers compared with high SES smokers has not previously been examined. METHODS 202,084 records of smokers in England who attended a NHS Stop Smoking Service between July 2010 and June 2011 were acquired. Smokers were followed-up by services at four weeks post quit date. Multilevel logistic regression models of CO validated quits were employed. Disadvantage was explored through the National Statistics Socio-Economic Classification (NS-SEC) and by eligibility for free prescriptions, an indicator of low income amongst adults aged between 19 and 59 in England. RESULTS Affluent smokers were more likely to quit than disadvantaged smokers (OR 1.38 (1.35 to 1.42) for clients who paid for prescriptions compared to those eligible for free prescriptions). 80% of service clients received one-to-one counselling but open group forms of behavioural therapy were more successful (main effect OR 1.26 (1.12 to 1.41)) except amongst some of the most disadvantaged clients (long-term unemployed and prisoners). Closed groups were little deployed and they were not significantly more successful than one-to-one behavioural therapy after controls. Who delivered treatment did make a difference for some clients, with all but the most affluent less likely to be successful if they had been treated by a nurse compared with other types of advisers, including smoking cessation specialists (main effect OR 0.73 (0.65 to 0.83)). CONCLUSION This study provides further evidence that disadvantaged smokers find quitting more difficult even when they have attended a smoking cessation programme. The findings suggest that open groups should be promoted, although they may not be as effective as other forms of behavioural therapy for the long-term unemployed or prisoners. Further research is required to explore why most groups of smokers who attended services staffed by nurses were less likely to quit than those who received treatment from other types of advisors.

Abstract
BACKGROUND CONSORT guidelines call for precise reporting of behavior change interventions: we need rigorous methods of characterizing active content of interventions with precision and specificity. OBJECTIVES The objective of this study is to develop an extensive, consensually agreed hierarchically structured taxonomy of techniques [behavior change techniques (BCTs)] used in behavior change interventions. METHODS In a Delphi-type exercise, 14 experts rated labels and definitions of 124 BCTs from six published classification systems. Another 18 experts grouped BCTs according to similarity of active ingredients in an open-sort task. Inter-rater agreement amongst six researchers coding 85 intervention descriptions by BCTs was assessed. RESULTS This resulted in 93 BCTs clustered into 16 groups. Of the 26 BCTs occurring at least five times, 23 had adjusted kappas of 0.60 or above. CONCLUSIONS "BCT taxonomy v1," an extensive taxonomy of 93 consensually agreed, distinct BCTs, offers a step change as a method for specifying interventions, but we anticipate further development and evaluation based on international, interdisciplinary consensus.

METHODS We selected independent-living Canadians aged ≥55 using random-digit-dial telephone calls. Respondents were randomly assigned to answer 1 of 2 surveys eliciting barriers and facilitators potentially influencing either CPR training or performance. We developed survey instruments using the Theory of Planned Behavior, measuring salient attitudes, social influences, and control beliefs. RESULTS Demographics for the 412 respondents (76.4% national response rate): Mean age 66, 58.7% female, 54.9% married, 58.0% CPR trained (half >10 years ago). Mean intentions to take CPR training in the next 6 months or to perform CPR on a victim were relatively high (3.6 and 4.1 out of 5). Attitudinal beliefs were most predictive of respondents' intentions to receive training or perform CPR (Adjusted OR; 95%CI were 1.81; 1.41-2.32 and 1.63; 1.26-2.04 respectively). Respondents who believed CPR could save a life, were employed, and had seen CPR advertised had the highest intention to receive CPR training. Those who believed CPR should be initiated before EMS arrival, were proactive in a group, and felt confident in their CPR skills had the highest intention to perform CPR. INTERPRETATION Attitudinal beliefs were most predictive of respondents' intention to complete CPR training or perform CPR on a real victim. Behavioral change techniques targeting these specific beliefs are most likely to make an impact.

Abstract
Tobacco smoke is the leading cause of preventable premature death worldwide. While the majority of smokers would like to stop, the habitual and addictive nature of smoking makes cessation difficult. Clinical guidelines suggest that smoking cessation interventions should include both behavioural support and pharmacotherapy (e.g. nicotine replacement therapy). This commentary paper focuses on the important role of behavioural interventions in encouraging and supporting smoking cessation attempts. Recent developments in the field are discussed, including ‘cut-down to quit’, the behaviour change techniques taxonomy (BCTT) and very brief advice (VBA) on smoking. The paper concludes with a discussion of the important role that health professionals can and should play in the delivery of smoking cessation interventions.

Abstract
Rates of childhood obesity are increasing, and it is essential to identify the active components of interventions aiming to prevent and manage obesity in children. A systematic review of behaviour change interventions was conducted to find evidence of behaviour change techniques (BCTs) that are most effective in changing physical activity and/or eating behaviour for the prevention or management of childhood obesity. An electronic search was conducted for randomised controlled trials published between January 1990 and December 2009. Of 4309 titles and abstracts screened, full texts of 135 articles were assessed, of which 17 published articles were included in this review. Intervention descriptions were coded according to the behaviour-specific CALO-RE taxonomy of BCTs. BCTs were identified and compared across obesity management (n=9) vs prevention (n=8) trials. To assess the effectiveness of individual BCTs, trials were further divided into those that were effective (defined as either a group reduction of at least 0.13 body mass index (BMI) units or a significant difference in BMI between intervention and control groups at follow-up) vs non-effective (reported no significant differences between groups). We reliably identified BCTs utilised in effective and non-effective prevention and management trials. To illustrate the relative effectiveness of each BCT, effectiveness ratios were calculated as the ratio of the number of times each BCT was a component of an intervention in an effective trial divided by the number of times they were a component of all trials. Results indicated six BCTs that may be effective components of future management interventions (provide information on the consequences of behaviour to the individual, environmental restructuring, prompt practice, prompt identification as role model/position advocate, stress management/emotional control training and general communication skills training), and one that may be effective in prevention interventions (prompting generalisation of a target behaviour). We identified that for management trials, providing information on the consequences of behaviour in general was a feature of non-effective interventions and for prevention trials, providing information on the consequences of behaviour in general, providing rewards contingent on successful behaviour and facilitating social comparison were non-effective. To design effective behaviour change programmes for the prevention and management of childhood obesity, we would recommend utilising the BCTs identified as effective in this review. The impact on intervention effectiveness of combining BCTs should be the topic of further research.

Abstract
BACKGROUND We sought to identify perceived barriers and facilitators to cardiopulmonary resuscitation (CPR) training and performing CPR among people above the age of 55 years. METHODS We conducted semistructured qualitative interviews with a purposive sample of independent-living individuals aged 55 years and older from urban and rural settings. We developed an interview guide based on the constructs of the Theory of Planned Behaviour, which elicits salient attitudes, social influences and control beliefs potentially influencing CPR training and performance. Interviews were recorded, transcribed verbatim and analysed until achieving data saturation. Two independent reviewers performed inductive analyses to identify emerging themes, and ranked them by way of consensus. RESULTS Demographics for the 24 interviewees: mean age 71.4 years, women 58.3%, urban location 75.0%, single dwelling 58.3%, CPR training 79.2% and prior CPR on real victim 8.3%. Facilitators of CPR training included: (1) classes in a convenient location; (2) more advertisements; and (3) having a spouse. Barriers to taking CPR training included: (1) perception of physical limitations; (2) time commitment; and (3) cost. Facilitators of providing CPR included: (1) 9-1-1 CPR instructions; (2) reminders/pocket cards; and (3) frequent but brief updates. Barriers to providing CPR included: (1) physical limitations; (2) lack of confidence; and (3) ambivalence of duty to act in a large group. CONCLUSIONS We identified key facilitators and barriers for CPR training and performance in a purposive sample of individuals aged 55 years and older.

The role of action planning and plan enactment for smoking cessation. BMC Public Health 2013; 13:393.

Abstract
Background Several studies have reemphasized the role of action planning. Yet, little attention has been paid to the role of plan enactment. This study assesses the determinants and the effects of action planning and plan enactment on smoking cessation. Methods One thousand and five participants completed questionnaires at baseline and at follow-ups after one and six months. Factors queried were part of the I-Change model. Descriptive analyses were used to assess which plans were enacted the most. Multivariate linear regression analyses were used to assess whether the intention to quit smoking predicted action planning and plan enactment, and to assess which factors would predict quitting behavior. Subsequently, both multivariate and univariate regression analyses were used to assess which particular action plans would be most effective in predicting quitting behavior. Similar analyses were performed among a subsample of smokers prepared to quit within one month. Results Smokers who intended to quit smoking within the next month had higher levels of action planning than those intending to quit within a year. Additional predictors of action planning were being older, being female, having relatively low levels of cigarette dependence, perceiving more positive and negative consequences of quitting, and having high self-efficacy toward quitting. Plan enactment was predicted by baseline intention to quit and levels of action planning. Regression analysis revealed that smoking cessation after six months was predicted by low levels of depression, having a non-smoking partner, the intention to quit within the next month, and plan enactment. Only 29% of the smokers who executed relatively few plans had quit smoking versus 59% of the smokers who executed many plans. The most effective preparatory plans for smoking cessation were removing all tobacco products from the house and choosing a specific date to quit. Conclusion Making preparatory plans to quit smoking is important because it also predicts plan enactment, which is predictive of smoking cessation. Not all action plans were found to be predictive of smoking cessation. The effects of planning were not very much different between the total sample and smokers prepared to quit within one month.

Abstract
BACKGROUND Effectiveness of evidence-based behaviour change interventions is likely to be undermined by failure to deliver interventions as planned. Behavioural support for smoking cessation can be a highly cost-effective, life-saving intervention. However, in practice, outcomes are highly variable. Part of this may be due to variability in fidelity of intervention implementation. To date, there have been no published studies on this. The present study aimed to: evaluate a method for assessing fidelity of behavioural support; assess fidelity of delivery in two English Stop-Smoking Services; and compare the extent of fidelity according to session types, duration, individual practitioners, and component behaviour change techniques (BCTs). METHODS Treatment manuals and transcripts of 34 audio-recorded behavioural support sessions were obtained from two Stop-Smoking Services and coded into component BCTs using a taxonomy of 43 BCTs. Inter-rater reliability was assessed using percentage agreement. Fidelity was assessed by examining the proportion of BCTs specified in the manuals that were delivered in individual sessions. This was assessed by session type (i.e., pre-quit, quit, post-quit), duration, individual practitioner, and BCT. RESULTS Inter-coder reliability was high (87.1%). On average, 66% of manual-specified BCTs were delivered per session (SD 15.3, range: 35% to 90%). In Service 1, average fidelity was highest for post-quit sessions (69%) and lowest for pre-quit (58%). In Service 2, fidelity was highest for quit-day (81%) and lowest for post-quit sessions (56%). Session duration was not significantly correlated with fidelity. Individual practitioner fidelity ranged from 55% to 78%. Individual manual-specified BCTs were delivered on average 63% of the time (SD 28.5, range: 0 to 100%). CONCLUSIONS The extent to which smoking cessation behavioural support is delivered as specified in treatment manuals can be reliably assessed using transcripts of audiotaped sessions. This allows the investigation of the implementation of evidence-based practice in relation to smoking cessation, a first step in designing interventions to improve it. There are grounds for believing that fidelity in the English Stop-Smoking Services may be low and that routine monitoring is warranted.

Abstract
Introduction: While numerous barriers to smoking cessation in pregnancy have been identified, less is known about the role of pregnant smokers’ beliefs in promoting and inhibiting abstinence. This study explored these beliefs and how they might interact with psychosocial factors related to pregnancy and antenatal care.Methods: In-depth face-to-face semi-structured interviews were conducted with 20 women with experience of prenatal smoking. Grounded theory and the constant comparative approach guided the analysis towards a theoretical explanation of the women's experiences.Results: Cognitive dissonance generated by the discrepancy between smoking-related prenatal harm beliefs and continued smoking was a strong motivator to quit. However, difficulty in quitting led many to resolve this dissonance by endorsing disengagement beliefs which downplayed the threat of smoking. Four main types of disengagement belief were identified. The tendency to endorse disengagement beliefs appeared to be influenced by two factors: uncertainty about how smoking caused foetal harm and reassurance from health professionals and others that reduced smoking was sufficient for harm minimisation.Conclusions: Disengagement belief endorsement is common among pregnant smokers and enables the justification of continued smoking, potentially hindering efforts to quit. Increased promotion of complete abstinence by antenatal care professionals and health education interventions targeting risk comprehension and disengagement belief endorsement should be considered to promote greater efforts to quit among pregnant smokers.

Abstract
INTRODUCTION Behavioral support interventions for smoking cessation are typically complex, involving multiple interacting component behavior change techniques (BCTs). Precise reporting of intervention content is important for progress in the field. This study assessed the adequacy of published descriptions of the content of smoking cessation behavioral support interventions. METHODS About 152 trials of behavioral support were identified from Cochrane reviews. Authors were contacted up to 3 times requesting a copy of the intervention manual. Descriptions of intervention content in manuals and the corresponding publications were coded into component BCTs using an established taxonomy. The proportion of manual-specified content reported in subsequent trial reports was examined. RESULTS Manuals were received for 28 interventions published between 1992 and 2008. An average of 27 BCTs were identified per manual (range: 5-56), whereas published descriptions averaged only 12 (range: 3-26) (t[27] = 4.15, p < .001 for the difference). CONCLUSIONS Published reports of evaluations of smoking cessation behavioral support interventions typically mention fewer than half the behavior change techniques specified in the corresponding intervention manuals; this deficit in reporting could be remedied by journals insisting on full manuals being provided as supplementary electronic files.

Abstract
BACKGROUND This article reports a pilot study of a new smoking cessation website ('StopAdvisor'), which has been developed on the basis of PRIME theory, evidence, web-design expertise and user-testing. The aims were to i) evaluate whether cessation, website usage and satisfaction were sufficiently high to warrant a randomised controlled trial (RCT) and ii) assess whether outcomes were affected by socio-economic status. METHODS This was an uncontrolled pilot study. Two hundred and four adult daily smokers willing to make a serious quit attempt were included. All participants received support from 'StopAdvisor', which recommends a structured quit plan and a variety of evidence-based behaviour change techniques for smoking cessation. A series of tunnelled sessions and a variety of interactive menus provide tailored support for up to a month before quitting through until one-month post-quit (http://www.lifeguideonline.org/player/play/stopadvisordemonstration). The primary outcome was self-report of at least 1month of continuous abstinence collected at 2months post-enrolment and verified by saliva cotinine or anabasine. Usage was indexed by log-ins and page views. Satisfaction was assessed by dichotomous ratings of helpfulness, personal relevance, likelihood of recommendation and future use, which were collected using an online questionnaire at 2months post-enrolment. Outcomes according to socio-economic status were assessed. RESULTS At 8weeks post-enrolment, 19.6% (40/204) of participants were abstinent according to the primary outcome criteria (95% C.I.=14.1% to 25.1%). Participants viewed a mean of 133.5 pages (median=71.5) during 6.4 log-ins (median=3). A majority of respondents rated the website positively on each of the four satisfaction `ratings (range=66.7% to 75.3%). There was no evidence of an effect of socio-economic status on abstinence (OR=1.01, C.I.=0.50-2.07), usage (page-views, t(202)=0.11, p=.91; log-ins, t(202)=0.21, p=.83), or satisfaction (helpfulness, OR=1.09, C.I.=0.41-2.88; personal relevance, OR=0.55, C.I.=0.20-1.56; recommendation, OR=0.98, C.I.=0.34-2.81; use in future, OR=1.45, C.I.=0.49-4.27). CONCLUSIONS The systematic application of theory, evidence, web-design expertise, and user-testing has resulted in a website that shows sufficiently promising efficacy and usability to warrant evaluation in a RCT. The website appears to be similarly effective and acceptable to users across the social spectrum.

Abstract
AIMS A network of Stop Smoking Services has been set up within the National Health Service (NHS) in England. The services deliver a combination of behavioural support and medication. It is important to establish the degree of variability in quit rates attributable to differences between individual practitioners, to gauge the scope for improvement by training and professional support. The aim of the present analysis was to examine how far short-term quit rates depend on the practitioner delivering the intervention after adjusting for potential confounding variables. DESIGN Observational study using routinely collected data. SETTING Thirty-one NHS Stop Smoking Services in England. PARTICIPANTS Data from 46,237 one-to-one treatment episodes (supported quit attempts) delivered by specialist practitioners. MEASUREMENTS Three-level logistic regression models were fitted for carbon monoxide (CO)-validated short-term (4-week) quit rates. Models adjusted for age, gender, exemption from prescription charges, medication and intervention setting for each treatment episode, number of clients for each practitioner and economic deprivation at the level of the Stop Smoking Service. Secondary analyses included (i) the heaviness-of-smoking index (HSI) as predictor and (ii) 4-week quit rates whether or not confirmed by CO. FINDINGS Differences between individual specialist practitioners explained 7.6% of the variance in CO-verified quit rates after adjusting for client demographics, intervention characteristics and practitioner and service variables (P < 0.001). HSI had little impact on this figure; in quits not necessarily validated by CO, practitioners explained less variance. CONCLUSIONS Individual stop smoking practitioners appear to differ to a significant degree in effectiveness. It is important to examine what underlies these differences in order to improve selection, training and professional development.

Abstract
Reviews of internet-based behaviour-change interventions have shown that they can be effective but there is considerable heterogeneity and effect sizes are generally small. In order to advance science and technology in this area, it is essential to be able to build on principles and evidence of behaviour change in an incremental manner. We report the development of an interactive smoking cessation website, StopAdvisor, designed to be attractive and effective across the social spectrum. It was informed by a broad motivational theory (PRIME), empirical evidence, web-design expertise, and user-testing. The intervention was developed using an open-source web-development platform, 'LifeGuide', designed to facilitate optimisation and collaboration. We identified 19 theoretical propositions, 33 evidence- or theory-based behaviour change techniques, 26 web-design principles and nine principles from user-testing. These were synthesised to create the website, 'StopAdvisor' (see http://www.lifeguideonline.org/player/play/stopadvisordemonstration). The systematic and transparent application of theory, evidence, web-design expertise and user-testing within an open-source development platform can provide a basis for multi-phase optimisation contributing to an 'incremental technology' of behaviour change.

Abstract
BACKGROUND Interventions to reduce excessive alcohol consumption have a small but important effect, but a better understanding is needed of their 'active ingredients'. AIMS This study aimed to (i) develop a reliable taxonomy of behaviour change techniques (BCTs) used in interventions to reduce excessive alcohol consumption (not to treat alcohol dependence) and (ii) to assess whether use of specific BCTs in brief interventions might be associated with improved effectiveness. METHODS A selection of guidance documents and treatment manuals, identified via expert consultation, were analysed into BCTs by two coders. The resulting taxonomy of BCTs was applied to the Cochrane Review of brief alcohol interventions, and the associations between the BCTs and effectiveness were investigated using meta-regression. FINDINGS Forty-two BCTs were identified, 34 from guidance documents and an additional eight from treatment manuals, with average inter-rater agreement of 80%. Analyses revealed that brief interventions that included the BCT 'prompt self-recording' (P = 0.002) were associated with larger effect sizes. CONCLUSIONS It is possible to identify specific behaviour change techniques reliably in manuals and guidelines for interventions to reduce excessive alcohol consumption. In brief interventions, promoting self-monitoring is associated with improved outcomes. More research is needed to identify other behaviour change techniques or groupings of behaviour change techniques that can produce optimal results in brief interventions and to extend the method to more intensive interventions and treatment of alcohol dependence.

The ‘Txt2Stop’ SMS messaging programme has been found to double smokers’ chances of stopping. It is important to characterise the content of this information in terms of specific behaviour change techniques (BCTs) for the purpose of future development. This study aimed to (i) extend a proven system for coding BCTs to text messaging and (ii) characterise Txt2Stop using this system. A taxonomy previously used to specify BCTs in face-to-face behavioural support for smoking cessation was adapted for the Txt2Stop messages and inter-rater reliability for the adapted system assessed. The system was then applied to all the messages in the Txt2Stop programme to determine its profile in terms of BCTs used. The text message taxonomy comprised 34 BCTs. Inter-rater reliability was moderate, reaching a ceiling of 61% for the core program messages with all discrepancies readily resolved. Of 899 texts delivering BCTs, 218 aimed to maintain motivation to remain abstinent, 870 to enhance self-regulatory capacity or skills, 39 to promote use of adjuvant behaviours such as using stop-smoking medication, 552 to maintain engagement with the intervention and 24 were general communication techniques. The content of Txt2Stop focuses on helping smokers with self-regulation and maintaining engagement with the intervention. The intervention focuses to a lesser extent on boosting motivation to remain abstinent; little attention is given to promoting effective use of adjuvant behaviours such as use of nicotine replacement therapy. As new interventions of this kind are developed it will be possible to compare their effectiveness and relate this to standardised descriptions of their content using this system.

Abstract
Introduction: In English National Health Service (NHS) Stop Smoking Services, stop smoking practitioners provide behavioural support and medication to support smokers wanting to quit. There is a need to develop an evidence base for the training of such practitioners. This study evaluated a national face-to-face skills training course in behavioural support for practitioners. Methods: Data were gathered from 169 trainees attending the NHS Centre for Smoking Cessation and Training (NCSCT) courses between October 2010 and August 2011. They provided confidence in competence ratings for 16 core competences before, immediately following and 3 months after training. At 3-month follow-up, they also described what they believed were the most important learning outcomes. Trainees also provided course evaluations in the form of ratings (n = 386, courses not yet followed up included). Results: Confidence ratings increased overall by 40% immediately after the course and the higher level of confidence was maintained at 3-month follow-up; 92% agreed or strongly agreed that the course was very useful and very interesting; 90% that it was very enjoyable; 88% that it improved their skills and 87% that they would recommend it. The learning outcomes rated as most important reflected the relevant behaviour change techniques. Conclusion: The NCSCT skills training course appears to result in a substantial improvement in confidence in ability to deliver smoking cessation support and trainees evaluate it highly. The next step is to assess improvements in observed practice and success rates.

Abstract
OBJECTIVE Internet-based programs offer potential for practical, cost-effective chronic illness self-management programs. METHODS We report 12-month results of an Internet-based diabetes self-management program, with and without additional support, compared to enhanced usual care in a 3-arm practical randomized trial. Patients (n=463) were randomized: 77.3% completed 12-month follow-up. Primary outcomes were changes in health behaviors of healthy eating, physical activity, and medication taking. Secondary outcomes were hemoglobin A1c, body mass index, lipids, blood pressure, and psychosocial factors. RESULTS Internet conditions improved health behaviors significantly vs. usual care over the 12-month period (d for effect size=.09-.16). All conditions improved moderately on biological and psychosocial outcomes. Latinos, lower literacy, and higher cardiovascular disease risk patients improved as much as other participants. CONCLUSIONS The Internet intervention meets the reach and feasibility criteria for a potentially broad public health impact. However, 12-month magnitude of effects was small, suggesting that different or more intensive approaches are necessary to support long-term outcomes. Research is needed to understand the linkages between intervention and maintenance processes and downstream outcomes. PRACTICE IMPLICATIONS Automated self-management interventions should be tailored and integrated into primary care; maintenance of patient self-management can be enhanced through links to community resources.

Abstract
BACKGROUND Current reporting of intervention content in published research articles and protocols is generally poor, with great diversity of terminology, resulting in low replicability. This study aimed to extend the scope and improve the reliability of a 26-item taxonomy of behaviour change techniques developed by Abraham and Michie [Abraham, C. and Michie, S. (2008). A taxonomy of behaviour change techniques used in interventions. Health Psychology, 27(3), 379-387.] in order to optimise the reporting and scientific study of behaviour change interventions. METHODS Three UK study centres collaborated in applying this existing taxonomy to two systematic reviews of interventions to increase physical activity and healthy eating. The taxonomy was refined in iterative steps of (1) coding intervention descriptions, and assessing inter-rater reliability, (2) identifying gaps and problems across study centres and (3) refining the labels and definitions based on consensus discussions. RESULTS Labels and definitions were improved for all techniques, conceptual overlap between categories was resolved, some categories were split and 14 techniques were added, resulting in a 40-item taxonomy. Inter-rater reliability, assessed on 50 published intervention descriptions, was good (kappa = 0.79). CONCLUSIONS This taxonomy can be used to improve the specification of interventions in published reports, thus improving replication, implementation and evidence syntheses. This will strengthen the scientific study of behaviour change and intervention development.

Abstract
Background Improving the design and implementation of evidence-based practice depends on successful behaviour change interventions. This requires an appropriate method for characterising interventions and linking them to an analysis of the targeted behaviour. There exists a plethora of frameworks of behaviour change interventions, but it is not clear how well they serve this purpose. This paper evaluates these frameworks, and develops and evaluates a new framework aimed at overcoming their limitations. Methods A systematic search of electronic databases and consultation with behaviour change experts were used to identify frameworks of behaviour change interventions. These were evaluated according to three criteria: comprehensiveness, coherence, and a clear link to an overarching model of behaviour. A new framework was developed to meet these criteria. The reliability with which it could be applied was examined in two domains of behaviour change: tobacco control and obesity. Results Nineteen frameworks were identified covering nine intervention functions and seven policy categories that could enable those interventions. None of the frameworks reviewed covered the full range of intervention functions or policies, and only a minority met the criteria of coherence or linkage to a model of behaviour. At the centre of a proposed new framework is a 'behaviour system' involving three essential conditions: capability, opportunity, and motivation (what we term the 'COM-B system'). This forms the hub of a 'behaviour change wheel' (BCW) around which are positioned the nine intervention functions aimed at addressing deficits in one or more of these conditions; around this are placed seven categories of policy that could enable those interventions to occur. The BCW was used reliably to characterise interventions within the English Department of Health's 2010 tobacco control strategy and the National Institute of Health and Clinical Excellence's guidance on reducing obesity. Conclusions Interventions and policies to change behaviour can be usefully characterised by means of a BCW comprising: a 'behaviour system' at the hub, encircled by intervention functions and then by policy categories. Research is needed to establish how far the BCW can lead to more efficient design of effective interventions.
