Motivational interviewing in health care settings. Opportunities and limitations

Living well with diabetes: 24-month outcomes from a randomized trial of telephone-delivered weight loss and physical activity intervention to improve glycemic control

OBJECTIVE

To evaluate the effectiveness of a telephone-delivered behavioral weight loss and physical activity intervention targeting Australian primary care patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Pragmatic randomized controlled trial of telephone counseling (n = 151) versus usual care (n = 151). Reported here are 18-month (end-of-intervention) and 24-month (maintenance) primary outcomes of weight, moderate-to-vigorous-intensity physical activity (MVPA; via accelerometer), and HbA1c level. Secondary outcomes include dietary energy intake and diet quality, waist circumference, lipid levels, and blood pressure. Data were analyzed via adjusted linear mixed models with multiple imputation of missing data.

RESULTS

Relative to usual-care participants, telephone counseling participants achieved modest, but significant, improvements in weight loss (relative rate [RR] -1.42% of baseline body weight [95% CI -2.54 to -0.30% of baseline body weight]), MVPA (RR 1.42 [95% CI 1.06-1.90]), diet quality (2.72 [95% CI 0.55-4.89]), and waist circumference (-1.84 cm [95% CI -3.16 to -0.51 cm]), but not in HbA1c level (RR 0.99 [95% CI 0.96-1.02]), or other cardio-metabolic markers. None of the outcomes showed a significant change/deterioration over the maintenance period. However, only the intervention effect for MVPA remained statistically significant at 24 months.

CONCLUSIONS

The modest improvements in weight loss and behavior change, but the lack of changes in cardio-metabolic markers, may limit the utility, scalability, and sustainability of such an approach.

Motivational interviewing with primary care populations: a systematic review and meta-analysis

This meta-analysis synthesized the findings from randomized controlled trials (RCTs) of motivational interviewing (MI) for health behavior outcomes within primary care populations. Published and unpublished RCTs were identified using databases and online listservs. Studies were synthesized by outcome subgroup and meta-regression analyses were conducted to determine potential moderators accounting for heterogeneity within samples. Mean effect sizes ranged from .07 to .47; significant effect sizes were found for the adherence subgroup of studies (p = .04) and all outcomes combined (p = .02). Professional credentials of intervention deliverer were found to significantly moderate the association between MI and effect size in substance use subgroup (p = .0005) and all outcomes combined (p = .004). Mean effect sizes were largest in outcomes related to weight loss, blood pressure, and substance use. MI appears to be useful in clinical settings and as few as 1 MI session may be effective in enhancing readiness to change and action directed towards reaching health behavior-change goals.

Teachable moments for health behavior change and intermediate patient outcomes

OBJECTIVE

Teachable moments (TM) are opportunities created through physician-patient interaction and used to encourage patients to change unhealthy behaviors. We examine the effectiveness of TMs to increase patients' recall of advice, motivation to modify behavior, and behavior change.

METHODS

A mixed-method observational study of 811 patient visits to 28 primary care clinicians used audio-recordings of visits to identify TMs and other types of advice in health behavior change talk. Patient surveys assessed smoking, exercise, fruit/vegetable consumption, height, weight, and readiness for change prior to the observed visit and 6-weeks post-visit.

RESULTS

Compared to other identified categories of advice (i.e. missed opportunities or teachable moment attempts), recall was greatest after TMs occurred (83% vs. 49-74%). TMs had the greatest proportion of patients change in importance and confidence and increase readiness to change; however differences were small. TMs had greater positive behavior change scores than other categories of advice; however, this pattern was statistically non-significant and was not observed for BMI change.

CONCLUSION

TMs have a greater positive influence on several intermediate markers of patient behavior change compared to other categories of advice.

PRACTICE IMPLICATIONS

TMs show promise as an approach for clinicians to discuss behavior change with patients efficiently and effectively.

Podiatric physicians' perspectives on their role in promoting self-care in high-risk patients with diabetes

BACKGROUND

Foot self-care is key in preventing morbidity in high-risk diabetic patients. Motivational interviewing (MI) is an approach to encourage behavior change by patients that can be used in medical settings. The goal was to explore how podiatric physicians promote self-care in such patients and whether they use MI techniques.

METHODS

We conducted a 19-question online survey of US-based practicing podiatric physicians. Most answers were on a 5-point scale. The MI index was the sum of answers to five relevant questions.

RESULTS

Of 843 podiatric physicians, 86% considered foot self-care to be very important for high-risk diabetic patients, and 90% felt that it was their role to discuss foot self-care with them; 49% felt that they had training and were successful in promoting behavior change, but most were definitely (38%) or possibly (46%) interested in learning more. Only 24% of respondents scored at least 15 of 20 on the MI index. Higher MI scores were associated with more face time and more time discussing foot self-care but were not related to podiatric physicians' age, sex, geographic location, percentage of time in surgery, or years in practice. Reported barriers to counseling were lack of reimbursed time and poor patient engagement.

CONCLUSIONS

Most podiatric physicians view self-care behavior among high-risk diabetic patients and their role in promoting it as very important; most feel already proficient, but only a few demonstrate MI skills; most are willing to learn more. Success in behavioral counseling, such as MI, is likely to require more time and may be encouraged by a move from fee-for-service to outcome-based reimbursement.

Comparative effectiveness of peer leaders and community health workers in diabetes self-management support: results of a randomized controlled trial

OBJECTIVE

To compare a peer leader (PL) versus a community health worker (CHW) telephone outreach intervention in sustaining improvements in HbA1c over 12 months after a 6-month diabetes self-management education (DSME) program.

RESEARCH DESIGN AND METHODS

One hundred and sixteen Latino adults with type 2 diabetes were recruited from a federally qualified health center and randomized to (1) a 6-month DSME program followed by 12 months of weekly group sessions delivered by PLs with telephone outreach to those unable to attend or (2) a 6-month DSME program followed by 12 months of monthly telephone outreach delivered by CHWs. The primary outcome was HbA1c. Secondary outcomes were cardiovascular disease risk factors, diabetes distress, and diabetes social support. Assessments were conducted at baseline, 6, 12, and 18 months.

RESULTS

After DSME, the PL group achieved a reduction in mean HbA1c (8.2-7.5% or 66-58 mmol/mol, P < 0.0001) that was maintained at 18 months (-0.6% or -6.6 mmol/mol from baseline [P = 0.009]). The CHW group also showed a reduction in HbA1c (7.8 vs. 7.3% or 62 vs. 56 mmol/mol, P = 0.0004) post-6 month DSME; however, it was attenuated at 18 months (-0.3% or -3.3 mmol/mol from baseline, within-group P = 0.234). Only the PL group maintained improvements achieved in blood pressure at 18 months. At the 18-month follow-up, both groups maintained improvements in waist circumference, diabetes support, and diabetes distress, with no significant differences between groups.

CONCLUSIONS

Both low-cost maintenance programs led by either a PL or a CHW maintained improvements in key patient-reported diabetes outcomes, but the PL intervention may have additional benefit in sustaining clinical improvements beyond 12 months.

Impact of an adherence intervention on the effectiveness of tenofovir gel in the CAPRISA 004 trial

High adherence is important in microbicide trials, but no adherence interventions to date have demonstrated empiric improvements in microbicide adherence or effectiveness. Approximately midway during the CAPRISA 004 trial, we implemented a novel adherence intervention (Adherence Support Program-ASP), based on an Information-Motivation-Behavioral Skills model and incorporating a Motivational Interviewing approach. We assessed the impact of the ASP on adherence and tenofovir gel effectiveness using a before-and-after comparison. Of the 889 women in the trial, 774 contributed 486.1 women-years of follow-up pre-ASP and 828 contributed 845.7 women-years of follow-up post-ASP. Median adherence rose from 53.6 % pre-ASP to 66.5 % post-ASP. Detectable tenofovir levels increased from 40.6 % pre-ASP to 62.5 % post-ASP in 64 women who had paired tenofovir drug samples. Gel effectiveness improved post-ASP; HIV incidence in the tenofovir gel arm was 24 % lower pre-ASP compared to 47 % lower post-ASP. Following implementation of the ASP, microbicide adherence improved with a concomitant increase in the effectiveness of tenofovir gel.

Adherence in the CAPRISA 004 tenofovir gel microbicide trial

High adherence is key to microbicide effectiveness. Here we provide a description of adherence interventions and the adherence rates achieved in the CAPRISA 004 Tenofovir gel trial. Adherence support for the before-and-after dosing strategy (BAT 24) was provided at enrolment and at each monthly study visit. This initially comprised individual counselling and was replaced midway by a structured theory-based adherence support program (ASP) based on motivational interviewing. The 889 women were followed for an average of 18 months and attended a total of 17,031 monthly visits. On average women reported five sex acts and returned 5.9 empty applicators per month. The adherence rate based on applicator count in relation to all reported sex acts was 72.2 % compared to the 82.0 % self-reported adherence during the last sex act. Adherence support activities, which achieve levels of adherence similar to or better than those achieved by the CAPRISA 004 ASP, will be critical to the success of future microbicide trials.

Review of the integrity of a Self Administered Motivational Instrument

BACKGROUND

Motivational interviewing (MI) was developed by Miller and Rollnick as an evidence-based counselling approach for use in supporting people with alcohol problems. Over the years the principles and spirit of MI have been reviewed and fine-tuned and the approach has been embraced by practitioners worldwide and across fields. Since 2001 a number of instruments have been designed to evaluate the fidelity of MI practice. For the purposes of this study, one such instrument is used to assess a self-administered motivational instrument, known as the SAMI, which takes the interviewer role.

OBJECTIVES

The SAMI is evaluated against the MITI 3.1.1, which is designed to assess the extent to which MI interventions perform on five global dimensions. These are evocation, collaboration, autonomy/support, direction and empathy.

DESIGN

The SAMI was assembled based on the principles and spirit of MI, problem solving and goal-setting. The targeted behaviour changes were student learning styles and approaches to study.

SETTING

The SAMI was distributed, completed and submitted electronically via the university virtual learning environment.

PARTICIPANTS

Thirty three mature students of a university which delivered online nursing programme were invited to complete the SAMI. Of these, 25 submitted completed transcripts.

METHODS

Transcripts of a sample of six completed SAMIs were assessed by a group of teachers and researchers with experience in the use and evaluation of MI, using five-point Likert scales to assess the SAMI on the five dimensions.

RESULTS

Overall, an average score exceeding 4.5 was attained across the five dimensions. Conventionally, such a score is recognised as competency in MI. However, on one dimension (empathy), the rating was three.

CONCLUSIONS

This current research confirms that global principles have been observed in the online delivery of MI using the SAMI to probe approaches to study.

Feasibility and impact of Creciendo Sanos, a clinic-based pilot intervention to prevent obesity among preschool children in Mexico City

BACKGROUND

Mexico has the highest adult overweight and obesity prevalence in the Americas; 23.8% of children <5 years old are at risk for overweight and 9.7% are already overweight or obese. Creciendo Sanos was a pilot intervention to prevent obesity among preschoolers in Instituto Mexicano del Seguro Social (IMSS) clinics.

METHODS

We randomized 4 IMSS primary care clinics to either 6 weekly educational sessions promoting healthful nutrition and physical activity or usual care. We recruited 306 parent-child pairs: 168 intervention, 138 usual care. Children were 2-5 years old with WHO body mass index (BMI) z-score 0-3. We measured children's height and weight and parents reported children's diet and physical activity at baseline and 3 and 6-month follow-up. We analyzed behavioral and BMI outcomes with generalized mixed models incorporating multiple imputation for missing values.

RESULTS

93 (55%) intervention and 96 (70%) usual care families completed 3 and 6-month follow-up. At 3 months, intervention v. usual care children increased vegetables by 6.3 servings/week (95% CI, 1.8, 10.8). In stratified analyses, intervention participants with high program adherence (5-6 sessions) decreased snacks and screen time and increased vegetables v. usual care. No further effects on behavioral outcomes or BMI were observed. Transportation time and expenses were barriers to adherence. 90% of parents who completed the post-intervention survey were satisfied with the program.

CONCLUSIONS

Although satisfaction was high among participants, barriers to participation and retention included transportation cost and time. In intention to treat analyses, we found intervention effects on vegetable intake, but not other behaviors or BMI.

Evaluation of systematic assessment of asthma-like symptoms and tobacco smoke exposure in early childhood by well-child professionals: a randomised trial

OBJECTIVES

This study aimed to evaluate the effectiveness of systematic assessment of asthma-like symptoms and environmental tobacco smoke (ETS) exposure during regular preventive well-child visits between age 1 and 4 years by well-child professionals.

METHODS

Sixteen well-child centres in Rotterdam, the Netherlands, were randomised into 8 centres where the brief assessment form regarding asthma-like symptoms and ETS exposure was used and 8 centres that applied usual care. 3596 and 4179 children (born between April 2002 and January 2006) and their parents visited the intervention and control centres, respectively. At child's age 6 years, physician-diagnosed asthma ever, wheezing, fractional exhaled nitric oxide (FeNO), airway resistance (Rint), health-related quality of life (HRQOL) and ETS exposure at home ever were measured. Linear mixed models were applied.

RESULTS

No differences in asthma, wheezing, FeNO, Rint or HRQOL measurements between intervention and control group were found using multilevel regression in an intention-to-treat analysis (p>0.05). Children of whom the parents were interviewed by using the brief assessment form at the intervention well-child centres had a decreased risk on ETS exposure at home ever, compared to children who visited the control well-child centres, in an explorative per-protocol analysis (aOR = 0.71, 95% CI:0.59-0.87).

CONCLUSIONS

Systematic assessment and counselling of asthma-like symptoms and ETS exposure in early childhood by well-child care professionals using a brief assessment form was not effective in reducing the prevalence of physician-diagnosed asthma ever and wheezing, and did not improve FeNO, Rint or HRQOL at age 6 years. Our results hold some promise for interviewing parents and using information leaflets at well-child centres to reduce ETS exposure at home in preschool children.

A comparison of usual care, a patient-centred education intervention and motivational interviewing to improve medication adherence and readmissions of adults in an acute-care setting

AIM

To compare medication adherence and readmissions in patients who received usual care vs. patient-centred interventions.

BACKGROUND

Medication adherence is a complex behaviour that may be improved with patient-centred strategies.

METHOD

A non-concurrent convenience sample of 303 hospitalised patients received either usual care (n = 98) or patient-centred interventions (n = 205). Intervention patients received teach-back and medication tools (n = 137) or motivational interviewing (n = 68). Data were collected at discharge (T1), at 48-72 hours (T2) and 30 days after discharge (T3).

RESULTS

No significant differences were found in medication adherence, therapeutic alliance, patients' experience and readmissions between groups. Patients in the motivational interview group reported lower confidence with medication adherence at T1 (P = 0.01) and T2 (P = 0.00) than the patient-centred intervention group. Motivational interviewing was a significant predictor (β = -1.55, P = 0.01, OR 0.21, 95% CI 0.06, 0.72) of fewer readmissions.

CONCLUSION

Overall, patients reported very low levels of non-adherence and very high levels of confidence and importance of medication adherence.

IMPLICATIONS FOR NURSING MANAGEMENT

Medication adherence continues to be an important area for clinical inquiry. For those patients who lack confidence for medication adherence, comprehensive patient-centred strategies such as motivational interviewing may improve treatment outcomes.

The poetics of therapeutic practice: motivational interviewing and the powers of pause

Motivational interviewing (MI) is an increasingly prominent behavioral therapy that draws from and claims to synthesize two American therapeutic traditions long thought to be antithetical-"client-centered" and "directive" approaches. This paper proposes that MI achieves its hallmark "client-centered directiveness" through the aesthetic management of the therapeutic encounter, and more particularly, through MI practitioners' marked use of silence. Drawing on data collected during the ethnographic study of MI trainings and the formal analysis of video-recorded MI sessions that are commonly used as models in such trainings, we identify three patterns of pause that regularly fall at specific grammatical junctures within seasoned MI practitioners' turns-at-talk. We demonstrate how these pauses allow MI practitioners to subtly direct the conversation while simultaneously displaying unequivocal signs of client-centeredness. In other words, we show how and explain why the poetics of pause matter to MI. In presenting this case, we more generally highlight practice poetics-that is, the aesthetic management of the style and delivery of a professional message with a particular practical aim in mind-suggesting that this is a central if under-appreciated aspect of therapeutic practices.

Motivational interviewing with parents of overweight children: study design and methods for the NOURISH + MI study

There is an urgent need for innovative approaches to pediatric obesity treatment. There is also a demand for targeted strategies that reduce attrition and improve treatment adherence. Intervening exclusively with parents of overweight children is a novel approach with demonstrated efficacy in reducing child body mass index (BMI) percentile. Motivational interviewing (MI), a brief communication style for exploring and resolving ambivalence about behavior change, might enhance treatment engagement when implemented as part of obesity interventions. The aim of this report is to provide the rationale and methods for a novel study of MI with parents in the treatment of their children's overweight. We designed and are currently implementing NOURISH+MI, a randomized controlled trial examining the feasibility and efficacy of an adjunct values-based MI intervention, implemented within a culturally-tailored parent intervention for overweight children ages 5-11 years, NOURISH(+) (Nourishing Our Understanding of Role modeling to Improve Support and Health). Specifically, we are randomly assigning 60 parents to this adjunctive treatment, and investigating if adding two MI sessions prior to the NOURISH(+) group intervention will enhance treatment effects. We will be able to compare NOURISH+MI participants with those from the two NOURISH(+) treatment conditions (NOURISH(+) and control). We hypothesize that children whose parents participate in NOURISH+MI will demonstrate lower attrition and greater adherence with NOURISH(+), ultimately leading to greater treatment effects, compared with children whose parents are randomized to NOURISH(+) or a control group. Findings will contribute to the emerging literature examining the efficacy of MI within pediatric obesity interventions.

The effectiveness of motivational interviewing for health behaviour change in primary care settings: a systematic review

Motivational interviewing (MI) is a patient-centred approach to behaviour change that was originally developed in the addiction field but has increasingly been applied to public health settings with a focus on health promotion. The purpose of this review was to examine the evidence base for MI interventions in primary care settings with non-clinical populations to achieve behaviour change for physical activity, dietary behaviours and/or alcohol intake. We also sought to explore the specific behaviour change techniques included in MI interventions within primary care. Electronic databases were searched for relevant articles and 33 papers met inclusion criteria and were included. Approximately 50% of the included studies (n = 18) demonstrated positive effects in relation to health behaviour change. The efficacy of MI approaches is unclear given the inconsistency of MI descriptions and intervention components. Furthermore, research designs that do not isolate the effects of MI make it difficult to determine the effectiveness of such approaches. We offer a number of recommendations for researchers and practitioners seeking to include MI within behaviour change interventions to help improve the quality of the research and the effectiveness of MI-based interventions within primary care settings.

School nurses' experiences with motivational interviewing for preventing childhood obesity

Motivational interviewing is a counseling method used to bring about behavior change; its application by school nurses for preventing obesity in children is still new. This study, based on in-depth interviews with 12 school nurses, shows how school nurses adapted motivational interviewing and integrated it into their daily practice along with other methods they knew from the past. Three dilemmas for school nurses were revealed: when the child was severely overweight and the parents did not perceive this as a problem, when the child and the parents were at different stages of motivation to change, and when applying an individualized approach such as motivational interviewing for preventing a complex societal problem, in this instance obesity. The study raises an important issue to consider, with implications for school nursing and obesity prevention: motivational interviewing as either a counseling method or a prevention strategy.

Promotion of a healthy lifestyle among 5-year-old overweight children: health behavior outcomes of the 'Be active, eat right' study

BACKGROUND

This study evaluates the effects of an intervention performed by youth health care professionals on child health behaviors. The intervention consisted of offering healthy lifestyle counseling to parents of overweight (not obese) 5-year-old children. Effects of the intervention on the child having breakfast, drinking sweet beverages, watching television and playing outside were evaluated.

METHODS

Data were collected with the 'Be active, eat right' study, a cluster randomized controlled trial among nine youth health care centers in the Netherlands. Parents of overweight children received lifestyle counseling according to the intervention protocol in the intervention condition (n = 349) and usual care in the control condition (n = 288). Parents completed questionnaires regarding demographic characteristics, health behaviors and the home environment at baseline and at 2-year follow-up. Cluster adjusted regression models were applied; interaction terms were explored.

RESULTS

The population for analysis consisted of 38.1% boys; mean age 5.8 [sd 0.4] years; mean BMI SDS 1.9 [sd 0.4]. There were no significant differences in the number of minutes of outside play or television viewing a day between children in the intervention and the control condition. Also, the odds ratio for having breakfast daily or drinking two or less glasses of sweet beverages a day showed no significant differences between the two conditions. Additional analyses showed that the odds ratio for drinking less than two glasses of sweet beverages at follow-up compared with baseline was significantly higher for children in both the intervention (p < 0.001) and the control condition (p = 0.029).

CONCLUSIONS

Comparison of the children in the two conditions showed that the intervention does not contribute to a change in health behaviors. Further studies are needed to investigate opportunities to adjust the intervention protocol, such as integration of elements in the regular well-child visit. The intervention protocol for youth health care may become part of a broader approach to tackle childhood overweight and obesity.

Increased mortality in schizophrenia due to cardiovascular disease - a non-systematic review of epidemiology, possible causes, and interventions

BACKGROUND

Schizophrenia is among the major causes of disability worldwide and the mortality from cardiovascular disease (CVD) is significantly elevated. There is a growing concern that this health challenge is not fully understood and efficiently addressed.

METHODS

Non-systematic review using searches in PubMed on relevant topics as well as selection of references based on the authors' experience from clinical work and research in the field.

RESULTS

In most countries, the standardized mortality rate in schizophrenia is about 2.5, leading to a reduction in life expectancy between 15 and 20 years. A major contributor of the increased mortality is due to CVD, with CVD mortality ranging from 40 to 50% in most studies. Important causal factors are related to lifestyle, including poor diet, lack of physical activity, smoking, and substance abuse. Recent findings suggest that there are overlapping pathophysiology and genetics between schizophrenia and CVD-risk factors, further increasing the liability to CVD in schizophrenia. Many pharmacological agents used for treating psychotic disorders have side effects augmenting CVD risk. Although several CVD-risk factors can be effectively prevented and treated, the provision of somatic health services to people with schizophrenia seems inadequate. Further, there is a sparseness of studies investigating the effects of lifestyle interventions in schizophrenia, and there is little knowledge about effective programs targeting physical health in this population.

DISCUSSION

The risk for CVD and CVD-related deaths in people with schizophrenia is increased, but the underlying mechanisms are not fully known. Coordinated interventions in different health care settings could probably reduce the risk. There is an urgent need to develop and implement effective programs to increase life expectancy in schizophrenia, and we argue that mental health workers should be more involved in this important task.

Pilot Study of Implementation of an Internet-Based Depression Prevention Intervention (CATCH-IT) for Adolescents in 12 US Primary Care Practices: Clinical and Management/Organizational Behavioral Perspectives

OBJECTIVE

To explore the implementation of CATCH-IT (Competent Adulthood Transition with Cognitive-behavioral Humanistic and Interpersonal Training), an Internet-based depression intervention program in 12 primary care sites, occurring as part of a randomized clinical trial comparing 2 versions of the intervention (motivational interview + Internet program versus brief advice + Internet program) in 83 adolescents aged 14 to 21 years recruited from February 1, 2007, to November 31, 2007.

METHOD

The CATCH-IT intervention model consists of primary care screening to assess risk, a primary care physician interview to encourage participation, and 14 online modules of Internet training to teach adolescents how to reduce behaviors that increase vulnerability to depressive disorders. Specifically, we evaluated this program from both a management/organizational behavioral perspective (provider attitudes and demonstrated competence) and a clinical outcomes perspective (depressed mood scores) using the RE-AIM model (Reach, Efficacy, Adoption, Implementation, and Maintenance of the intervention).

RESULTS

While results varied by clinic, overall, clinics demonstrated satisfactory reach, efficacy, adoption, implementation, and maintenance of the CATCH-IT depression prevention program. Measures of program implementation and management predicted clinical outcomes at practices in exploratory analyses.

CONCLUSION

Multidisciplinary approaches may be essential to evaluating the impact of complex interventions to prevent depression in community settings. Primary care physicians and nurses can use Internet-based programs to create a feasible and cost-effective model for the prevention of mental disorders in adolescents in primary care settings.

A diabetes peer support intervention that improved glycemic control: mediators and moderators of intervention effectiveness

OBJECTIVE In a randomized trial, a guided diabetes peer support intervention improved glycemic control (A1c), with a difference in A1c change between groups of 0.58% (p = 0.004). The current study examined whether improvements in insulin uptake and perceived diabetes social support mediated the intervention's impact on A1c. We also examined potential moderation by patients' health literacy, diabetes social support, or diabetes distress. METHODS We conducted secondary analyses for 212 type 2 diabetes patients participating in the trial using accepted methods for testing mediation and moderation effects.

RESULTS

Roughly half (49%, 95% CI: 3-80%) of the A1c effect was mediated by increased insulin use, while changes in diabetes social support had a negligible impact. A1c impacts varied across subgroups defined by baseline diabetes social support and functional health literacy (both p < 0.01). The intervention was particularly beneficial among patients with low baseline diabetes support or literacy levels. The intervention had a greater impact on A1c among patients with more frequent engagement in peer support calls (p < 0.01). DISCUSSION Patients receiving increased peer support had improved glycemic control largely due to their greater likelihood of initiating insulin. Greater intervention engagement was associated with stronger effects. The intervention had its greatest benefits among patients with low support or poorer health literacy.

I Can Help You Change! An Empathic Virtual Agent Delivers Behavior Change Health Interventions

We discuss our approach to developing a novel modality for the computer-delivery of Brief Motivational Interventions (BMIs) for behavior change in the form of a personalized On-Demand VIrtual Counselor (ODVIC), accessed over the internet. ODVIC is a multimodal Embodied Conversational Agent (ECA) that empathically delivers an evidence-based behavior change intervention by adapting, in real-time, its verbal and nonverbal communication messages to those of the user’s during their interaction. We currently focus our work on excessive alcohol consumption as a target behavior, and our approach is adaptable to other target behaviors (e.g., overeating, lack of exercise, narcotic drug use, non-adherence to treatment). We based our current approach on a successful existing patient-centered brief motivational intervention for behavior change---the Drinker’s Check-Up (DCU)---whose computer-delivery with a text-only interface has been found effective in reducing alcohol consumption in problem drinkers. We discuss the results of users’ evaluation of the computer-based DCU intervention delivered with a text-only interface compared to the same intervention delivered with two different ECAs (a neutral one and one with some empathic abilities). Users rate the three systems in terms of acceptance, perceived enjoyment, and intention to use the system, among other dimensions. We conclude with a discussion of how our positive results encourage our long-term goals of on-demand conversations , anytime, anywhere, with virtual agents as personal health and well-being helpers.

Teen CHAT: Development and utilization of a web-based intervention to improve physician communication with adolescents about healthy weight

OBJECTIVE

To describe the theoretical basis, use, and satisfaction with Teen CHAT, an online educational intervention designed to improve physician-adolescent communication about healthy weight.

METHODS

Routine health maintenance encounters between pediatricians and family practitioners and their overweight adolescent patients were audio recorded, and content was coded to summarize adherence with motivational interviewing techniques. An online educational intervention was developed using constructs from social cognitive theory and using personalized audio recordings. Physicians were randomized to the online intervention or not, and completed post-intervention surveys.

RESULTS

Forty-six physicians were recruited, and 22 physicians were randomized to view the intervention website. The educational intervention took an average of 54min to complete, and most physicians thought it was useful, that they would use newly acquired skills with their patients, and would recommend it to others. Fewer physicians thought it helped them address confidentiality issues with their adolescent patients.

CONCLUSION

The Teen CHAT online intervention shows potential for enhancing physician motivational interviewing skills in an acceptable and time-efficient manner.

PRACTICE IMPLICATIONS

If found to be effective in enhancing motivational interviewing skills and changing adolescent weight-related behaviors, wide dissemination will be feasible and indicated.

From research to practice: lay adherence counsellors' fidelity to an evidence-based intervention for promoting adherence to antiretroviral treatment in the Western cape, South Africa

In the Western Cape, lay counsellors are tasked with supporting antiretroviral (ARV) adherence in public healthcare clinics. Thirty-nine counsellors in 21 Cape Town clinics were trained in Options for Health (Options), an evidence-based intervention based on motivational interviewing (MI). We evaluated counsellors' ability to deliver Options for addressing poor adherence following 5 days training. Audio-recordings of counselling sessions collected following training were transcribed and translated into English. Thirty-five transcripts of sessions conducted by 35 counsellors were analysed for fidelity to the Options protocol, and using the Motivational Interviewing Treatment and Integrity (MITI) code. Counsellors struggled with some of the strategies associated with MI, such as assessing readiness-to-change and facilitating change talk. Overall, counsellors failed to achieve proficiency in the approach of MI according to the MITI. Counsellors were able to negotiate realistic plans for addressing patients' barriers to adherence. Further efforts aimed at strengthening the ARV adherence counselling programme are needed.

Shared decision-making in antihypertensive therapy: a cluster randomised controlled trial

Background

Hypertension is one of the key factors causing cardiovascular diseases. A substantial proportion of treated hypertensive patients do not reach recommended target blood pressure values. Shared decision making (SDM) is to enhance the active role of patients. As until now there exists little information on the effects of SDM training in antihypertensive therapy, we tested the effect of an SDM training programme for general practitioners (GPs). Our hypotheses are that this SDM training (1) enhances the participation of patients and (2) leads to an enhanced decrease in blood pressure (BP) values, compared to patients receiving usual care without prior SDM training for GPs.

Methods

The study was conducted as a cluster randomised controlled trial (cRCT) with GP practices in Southwest Germany. Each GP practice included patients with treated but uncontrolled hypertension and/or with relevant comorbidity. After baseline assessment (T0) GP practices were randomly allocated into an intervention and a control arm. GPs of the intervention group took part in the SDM training. GPs of the control group treated their patients as usual. The intervention was blinded to the patients. Primary endpoints on patient level were (1) change of patients’ perceived participation (SDM-Q-9) and (2) change of systolic BP (24h-mean). Secondary endpoints were changes of (1) diastolic BP (24h-mean), (2) patients’ knowledge about hypertension, (3) adherence (MARS-D), and (4) cardiovascular risk score (CVR).

Results

In total 1357 patients from 36 general practices were screened for blood pressure control by ambulatory blood pressure monitoring (ABPM). Thereof 1120 patients remained in the study because of uncontrolled (but treated) hypertension and/or a relevant comorbidity. At T0 the intervention group involved 17 GP practices with 552 patients and the control group 19 GP practices with 568 patients. The effectiveness analysis could not demonstrate a significant or relevant effect of the SDM training on any of the endpoints.

Conclusion

The study hypothesis that the SDM training enhanced patients’ perceived participation and lowered their BP could not be confirmed. Further research is needed to examine the impact of patient participation on the treatment of hypertension in primary care.

A randomized controlled trial of two different lengths of nicotine replacement therapy for smoking cessation

This study examined if 2-week free nicotine replacement therapy (NRT) would be more effective than 1-week free NRT to help smokers quit smoking at 6 and 12 months. In a single-blinded randomized controlled trial design, 562 Chinese smokers who attended a smoking cessation clinic in Hong Kong, China, were randomly allocated into two groups (A1 and A2): A1 (n = 284) received behavioural counselling with free NRT for 1 week; A2 (n = 278) received similar counselling with free NRT for 2 weeks. All subjects received printed self-help materials to support their quitting efforts. A structured questionnaire was used for data collection, including pattern of NRT use and self-reported 7-day point prevalence quit rate at 6 months and 12 months. Among the participants, the mean number of cigarettes smoked per day was 18.8 (SD = 10.9). By intention-to-treat analysis, 7-day point prevalence quit rates were not significantly different between A1 and A2 groups at 6-month (27.5% versus 27.3%; P = 0.97) and 12-month (21.1% versus 21.2%; P = 0.98) followup. The findings suggest that two-week free NRT was not more effective than 1-week free NRT to increase smoking cessation rate among Chinese smokers.

Impact of an integrated intervention program on atorvastatin adherence: a randomized controlled trial

BACKGROUND

This trial evaluated the effectiveness of an integrated intervention program that included a 3-to-5-minute nurse counseling session, copay relief cards, and a monthly newsletter on adherence to atorvastatin treatment.

METHODS AND RESULTS

A prospective, integrated (composed of nurse counseling, adherence tip sheet, copay relief card, opportunity to enroll in 12-week cholesterol management program) randomized interventional study was designed involving patients >21 years of age who were prescribed atorvastatin at a large single-specialty cardiovascular physician practice in Illinois from March 2010 to May 2011. Data from the practice's electronic medical record were matched/merged to IMS Health's longitudinal data. A total of 500 patients were enrolled (125 in the control arm; 375 in the intervention arm). After data linkage, 53 control patients and 155 intervention patients were included in the analysis.

RESULTS

Mean age was 67.8 years (control) and 69.5 years (intervention); 67.9% and 58.7%, respectively, were male. The mean 6-month adherence rate was 0.82 in both arms. The mean proportion of days covered for both the new-user control and intervention groups was the same, averaging 0.70 day (standard deviation [SD], 0.27 day); for continuing users, the proportion of days covered for the control group was 0.83 (SD, 0.24) and for the intervention group was 0.84 (SD, 0.22). For continuing users, the control group had mean persistent days of 151.6 (SD, 50.2) compared with 150.9 days (SD, 50.9) for the intervention group. New users had fewer persistent days (control 111.4 days, SD, 69.6 days; intervention 112.0 days, SD, 58.8 days) compared with continuing users. The Cox proportional hazards model of the risk of discontinuation with index therapy was not significantly different between the intervention and control groups (hazard ratio 0.83, P = 0.55).

CONCLUSION

The integrated intervention program did not significantly improve atorvastatin adherence relative to usual care in the studied patient population.

A Systematic Review of the Literature on Health and Wellness Coaching: Defining a Key Behavioral intervention in Healthcare

PRIMARY OBJECTIVE

Review the operational definitions of health and wellness coaching as published in the peer-reviewed medical literature.

BACKGROUND

As global rates of preventable chronic diseases have reached epidemic proportions, there has been an increased focus on strategies to improve health behaviors and associated outcomes. One such strategy, health and wellness coaching, has been inconsistently defined and shown mixed results.

METHODS

A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-guided systematic review of the medical literature on health and wellness coaching allowed for compilation of data on specific features of the coaching interventions and background and training of coaches.

RESULTS

Eight hundred abstracts were initially identified through PubMed, with 284 full-text articles ultimately included. The majority (76%) were empirical articles. The literature operationalized health and wellness coaching as a process that is fully or partially patient-centered (86% of articles), included patient-determined goals (71%), incorporated self-discovery and active learning processes (63%) (vs more passive receipt of advice), encouraged accountability for behaviors (86%), and provided some type of education to patients along with using coaching processes (91%). Additionally, 78% of articles indicated that the coaching occurs in the context of a consistent, ongoing relationship with a human coach who is trained in specific behavior change, communication, and motivational skills.

CONCLUSIONS

Despite disparities in how health and wellness coaching have been operationalized previously, this systematic review observes an emerging consensus in what is referred to as health and wellness coaching; namely, a patient-centered process that is based upon behavior change theory and is delivered by health professionals with diverse backgrounds. The actual coaching process entails goal-setting determined by the patient, encourages self-discovery in addition to content education, and incorporates mechanisms for developing accountability in health behaviors. With a clear definition for health and wellness coaching, robust research can more accurately assess the effectiveness of the approach in bringing about changes in health behaviors, health outcomes and associated costs that are targeted to reduce the global burden of chronic disease.

Adherence support approaches in biomedical HIV prevention trials: experiences, insights and future directions from four multisite prevention trials

Adherence is a critical component of the success of antiretroviral-based pre-exposure prophylaxis (PrEP) in averting new HIV-infections. Ensuring drug availability at the time of potential HIV exposure relies on self-directed product use. A deeper understanding of how to best support sustained PrEP adherence remains critical to current and future PrEP efforts. This paper provides a succinct synthesis of the adherence support experiences from four pivotal PrEP trials--Centre for the AIDS Programme of Research in South Africa (CAPRISA) 004, FEM-PrEP, Iniciativa Prophylaxis (iPrEx), and Vaginal and Oral Interventions to Control the Epidemic (VOICE). Notwithstanding variability in the design, population/cohort, formulation, drug, dosing strategy, and operationalization of adherence approaches utilized in each trial, the theoretical basis and experiences in implementation and monitoring of the approaches used by these trials provide key lessons for optimizing adherence in future research and programmatic scale-up of PrEP. Recommendations from across these trials include participant-centered approaches, separating measurement of adherence from adherence counseling, incorporating tailored strategies that go beyond education, fostering motivation, and addressing the specific context in which an individual incorporates and negotiates PrEP use.

Considerations and lessons learned from designing a motivational interviewing obesity intervention for young people attending dental practices: a study protocol paper

BACKGROUND

With the prevalence of child obesity increasing worldwide, and the consumption of sugar-sweetened beverages identified as a major contributor to obesity in adolescents, there is a need for effective interventions aimed at dietary behaviour change in this group. Primary dental care settings are in an ideal position to influence adolescents' dietary behaviours, yet have been under-utilised for this purpose. Motivational Interviewing (MI) has shown promise in influencing other health behaviours. However, there is lack of published methodologies on which to base the design of such interventions, and limited evidence on its effectiveness in influencing dietary change. We undertook a study to test the feasibility of a MI intervention aimed at reducing soft drink consumption in adolescents attending dental surgeries. We present the study design for the development and evaluation of the intervention.

METHOD

Ten dental practices in north London were randomised into control or intervention. Adolescent participants in control settings received routine advice and intervention participants received a brief MI intervention. The intervention was designed using comprehensive stakeholder engagement and consisted of 3-4 short MI sessions and a maintenance phase delivered by trained researchers through the use of age-specific resources. Process evaluation was carried out using qualitative and quantitative methods to assess intervention feasibility in a primary dental care setting.

DISCUSSION

By focussing on the development and evaluation of the intervention, this paper contributes to the limited available knowledge and identifies methodological considerations for undertaking a MI intervention for dietary change in adolescents in primary dental care settings.

Treatment of low back pain: randomized clinical trial comparing a multidisciplinary group-based rehabilitation program with oral drug treatment up to 12 months

BACKGROUND

This study aimed to examine the effects of a multidisciplinary treatment program on health-related quality of life of Iranian patients living with chronic low back, at 12 months follow-up.

METHODS

This study is an extended follow-up of an original randomized, controlled trial with registration number NCT00600197. In the present study 87 patients in an intervention group and 91 patients in a control group were assessed at 12 months follow-up. The intervention was a group-based multidisciplinary rehabilitation program which continued by monthly motivational consultation by telephone from 6 to 12 months after intervention. Data from three standard measures, Short Form 36 (SF-36), QDS and RDQ were collected at 3, 6 and 12 months follow-up and analyzed through repeated measures analysis of variance.

RESULTS

Despite the similarity between the two groups who completed the 6 month follow-up in terms of all baseline variables, there were significant differences between the two groups in all domains of the SF-36 scale, as well as QDS and RDQ scales (P < 0.05). Also, there were differences within each group over time in the SF-36 domains and disability measurements (P < 0.05). The physical function mean score differed significantly when the interaction between groups and time points was examined (P = 0.02).

CONCLUSION

This study indicates that the multidisciplinary program could improve the domains of health related quality of life and disability in chronic low back pain patients up to 12 months.

Parental perceptions of a motivational interviewing-based pediatric obesity prevention intervention

Motivational interviewing (MI) shows promise for pediatric obesity prevention, but few studies address parental perceptions of MI. The aim of this study was to identify correlates of parental perceptions of helpfulness of and satisfaction with a MI-based pediatric obesity prevention intervention. We studied 253 children 2 to 6 years of age in the intervention arm of High Five for Kids, a primary care-based randomized controlled trial. In multivariable models, parents born outside the United States (odds ratio [OR] = 8.81; 95% confidence interval [CI] = 2.44, 31.8), with lower household income (OR = 3.60; 95% CI = 1.03, 12.55), and with higher BMI (OR = 2.86; 95% CI = 1.07, 7.65) were more likely to perceive MI-based visits as helpful in improving children's obesity-related behaviors after the first year of the intervention. Parents of female (vs male), black (vs white), and Latino (vs white) children had lower intervention satisfaction. Our findings underscore the importance of tailoring pediatric obesity prevention efforts to target populations.

Population-based childhood overweight prevention: outcomes of the 'Be active, eat right' study

Objective

An overweight prevention protocol was used in the ‘Be active, eat right’ study; parents of overweight children (5 years) were offered healthy lifestyle counseling by youth health care professionals. Effects of the protocol on child BMI and waist circumference at age 7 years were evaluated.

Methods

A cluster RCT was conducted among nine youth health care centers in the Netherlands. Parents of overweight, not obese, children received lifestyle counseling and motivational interviewing according to the overweight prevention protocol in the intervention condition (n = 349) and usual care in the control condition (n = 288). Measurements were made of child height, weight and waist circumference at baseline and at a two-year follow-up; parents completed questionnaires regarding demographic characteristics. Linear mixed models were applied; interaction terms were explored.

Results

The analyzed population consisted of 38.1% boys; mean age 5.7 [sd: 0.4] years; mean BMI 18.1 [sd: 0.6], the median number of counseling sessions in the intervention condition was 2. The regression model showed no significant difference in BMI increase between the research conditions at follow-up (beta −0.16; 95% CI:−0.60 to 0.27; p = 0.463). There was a significant interaction between baseline BMI and research condition; children with a baseline BMI of 17.25 and 17.50 had a smaller increase in BMI at follow-up when allocated to the intervention condition compared to control condition (estimated adjusted mean difference −0.67 [se: 0.30] and −0.52 [se: 0.36]).

Conclusion

Mildly overweight children (baseline BMI 17.25 and 17.50) in the intervention condition showed a significantly smaller increase in BMI at follow-up compared to the control condition; there was no overall difference between intervention and control condition. Future research may explore and evaluate improvements of the prevention protocol.

Effects of nurse-led motivational interviewing of patients with chronic musculoskeletal pain in preparation of rehabilitation treatment (PREPARE) on societal participation, attendance level, and cost-effectiveness: study protocol for a randomized controlled trial

Background

Non-adherence and drop-out are major problems in pain rehabilitation. For patients with various health problems, motivational interviewing (MI) has shown promising effects to tackle these problems. In chronic pain patients, the effectiveness of MI is however unknown. Therefore, a MI-based pre-pain rehabilitation intervention (MIP) addressing motivation, expectations, and beliefs has been developed to prepare eligible patients for rehabilitation treatment.

Methods/design

Study design: A parallel randomized controlled trial including two interventions: a motivational interviewing pre-pain rehabilitation intervention (MIP) and a usual care (UC) control arm. Follow-up will be 6 months after completion of rehabilitation treatment.

Study population: One hundred and sixty (n = 80 per arm) patients with chronic non-specific musculoskeletal pain visiting an outpatient rehabilitation department, who are eligible to participate in an outpatient cognitive behavioral pain rehabilitation program.

Intervention: MIP consists of two sessions to prepare and motivate the patient for pain rehabilitation treatment and its bio psychosocial approach. UC consists of information and education about the etiology and the general rehabilitation approach of chronic pain. Both the MIP and UC contain two sessions of 45 to 60 minutes each.

Objective: The aim of the current study is to evaluate the effectiveness of MIP compared to UC in terms of an increase in the long-term level of societal participation and decrease of drop-out during rehabilitation treatment.

Main study endpoints: Primary outcome is the change in level of participation (according to the ICF-definition: ‘involvement in a life situation’) 6 months after completion of rehabilitation treatment. Secondary outcomes are adherence and treatment drop-out, disability, pain intensity, self-reported main complaints, (pain-specific) self-efficacy, motivation, and quality of life. Costs are calculated including the costs of the pre-treatment intervention, productivity losses, and healthcare utilization. Potential moderators and active ingredients of MI are explored. For the process evaluation, parameters such as MI fidelity, feasibility, and experiences are explored.

Discussion

The results of this study will provide evidence on the effectiveness of this MI-based pre-treatment in pain rehabilitation. Furthermore, a cost-effectiveness analysis and exploration of moderating and working mechanisms of MI and an extensive process evaluation takes place.

A randomized controlled trial of motivational interviewing to prevent risk for an alcohol-exposed pregnancy in the Western Cape, South Africa

AIM

To test the effectiveness of motivational interviewing (MI) to reduce the risk of an alcohol exposed pregnancy (AEP) in a high-risk population.

DESIGN

Randomized controlled trial.

SETTING

Rural population in the Western Cape, South Africa.

PARTICIPANTS

A total of 165 women aged 18-44 years at risk of AEP.

INTERVENTION

Five-session MI intervention.

MEASUREMENTS

Structured questionnaires were administered pre-intervention and at 3 and 12 months follow-up. The primary outcome measure was AEP at 12 months. Secondary outcomes were AEP at 3 months, and alcohol use and effective contraception at 3 and 12 months.

FINDINGS

There was a significant difference in the decline in the proportion of women at risk for an AEP in the MI group at 3 months (50 versus 24.59%; P = 0.004), maintained at 12 months (50.82 versus 28.12%; P = 0.009). In an intention-to-treat analysis these differences were also significant (32.93 versus 18.07%; P = 0.029; and 37.80 versus 21.69%; P = 0.024, respectively). The odds ratio for no longer being at risk of an AEP (MI versus control) at 12 months was 2.64 [95% confidence interval (CI): 1.18-5.94]. In the intention-to-treat analysis this ratio was 2.19 (95% CI: 1.05-4.65).

CONCLUSIONS

A five-session motivational interviewing intervention was found to be effective with women at risk of an alcohol-exposed pregnancy, and could be implemented as part of routine primary care clinic services in similar populations. The message of 'no alcohol in pregnancy' should be adapted to include better family planning and early recognition of pregnancy.

Evaluation of a web-based asthma management intervention program for urban teenagers: reaching the hard to reach

PURPOSE

Asthma interventions targeting urban adolescents are rare, despite a great need. Motivating adolescents to achieve better self-management of asthma is challenging, and the literature suggests that certain subgroups are more resistant than others. We conducted a school-based, randomized controlled trial (RCT) to evaluate Puff City, a Web-based, tailored asthma intervention, which included a referral coordinator, and incorporated theory-based strategies to target urban teens with characteristics previously found to be associated with lack of behavior change.

METHODS

To identify eligible teens, we administered questionnaires on asthma diagnoses and symptoms to ninth through 12th graders of participating schools during a scheduled English class. We randomized eligible, consenting students to Puff City (treatment) or generic asthma education (control).

RESULTS

We randomized 422 students (98% African-American, mean age = 15.6 years). At 12-month follow-up, adjusted odds ratios (aORs) (95% confidence intervals) indicated intervention benefit for treatment teens for symptom-days and restricted activity days (analyzed as categorical variables) as aOR = .49 (.24-.79), p = .006 and .53 (.32-.86), p = .010, respectively. Among teens meeting baseline criteria for rebelliousness, treatment teens reported fewer symptom-days, symptom-nights, school absences, and restricted activity days: aOR = .30 (.11-.80), .29 (.14-.64), .40 (.20-.78), and .23 (.10-.55); all p < .05. Among teens reporting low perceived emotional support, treatment students reported only fewer symptom-days than controls: aOR = .23 (.06-.88), p = .031. We did not observe statistically significant differences in medical care use.

CONCLUSIONS

Results suggest that a theory-based, tailored approach, with a referral coordinator, can improve asthma management in urban teens. Puff City represents a viable strategy for disseminating an effective intervention to high-risk and hard-to-reach populations.

Effectiveness of a motivational interviewing intervention on weight loss, physical activity and cardiovascular disease risk factors: a randomised controlled trial with a 12-month post-intervention follow-up

BACKGROUND

Intensive diet and physical activity interventions have been found to reduce cardiovascular disease (CVD) risk, but are resource intensive. The American Heart Association recently recommended motivational interviewing (MI) as an effective approach for low-intensity interventions to promote health-related outcomes such as weight loss. However, there is limited research evaluating the long-term effectiveness of MI-based interventions on health-related outcomes associated with CVD risk. The current research evaluated the effectiveness of a six-month low-intensity MI intervention in a UK primary-care setting in maintaining reductions in CVD risk factors at12 months post-intervention.

METHODS

Primary-care patients were randomised to an intervention group that received standard exercise and nutrition information plus up to five face-to-face MI sessions, delivered by a physical activity specialist and registered dietician over a 6-month period, or to a minimal intervention comparison group that received the standard information only. Follow-up measures of behavioural (vigorous and moderate physical activity, walking, physical activity stage-of-change, fruit and vegetable intake, and dietary fat intake) and biomedical (weight, body mass index [BMI], blood pressure, cholesterol) outcomes were taken immediately post-intervention and at a 12-month follow-up occasion.

RESULTS

Intent-to-treat analyses revealed significant differences between groups for walking and cholesterol. Obese and hypercholesterolemic patients at baseline exhibited significant improvements in BMI and cholesterol respectively among those allocated to the intervention group compared to the comparison group. Post-intervention improvements in other health-related outcomes including blood pressure, weight, and BMI were not maintained.

CONCLUSIONS

The present study suggests that a low-intensity MI counselling intervention is effective in bringing about long-term changes in some, but not all, health-related outcomes (walking, cholesterol levels) associated with CVD risk. The intervention was particularly effective for patients with elevated levels of CVD risk factors at baseline. Based on these findings future interventions should be conducted in a primary care setting and target patients with high risk of CVD. Future research should investigate how the long-term gains in health-related outcomes brought about by the MI-counselling intervention in the current study could be extended to a wider range of health outcomes.

Motivational interviewing within the different stages of change: an analysis of practice nurse-patient consultations aimed at promoting a healthier lifestyle

Combining the Stages of Change (SOC) model with Motivational Interviewing (MI) is seen as a helpful strategy for health care providers to guide patients in changing unhealthy lifestyle behaviour. SOC suggests that people are at different stages of motivational readiness for engaging in health behaviours and that intervention methods are most useful when tailored to a person's stage of change. However, it is unknown whether practice nurses (PNs) actually adapt their MI and more generic communication skills to a particular stage during real-life face-to-face consultations with their patients. The aim of this study was to explore whether and how PNs apply MI and general communication skills to the different SOC of patients, targeting behaviour change about smoking, alcohol use, dietary habits and/or physical activity. Real-life consultations between nineteen Dutch PNs and 103 patients were recorded on video between June 2010 and March 2011. All consultations focused on a discussion of patients' lifestyle behaviour. The Behaviour Change Counselling Index (BECCI) was used to code PNs' MI skills. Generic communication skills were rated with the MAAS-global. Patients' SOC was assessed for each consultation by observing the communication between patient and PN regarding the patient's current lifestyle behaviour. Multilevel analyses revealed that PNs adapt their MI skills to a patient's SOC to some extent. On average PNs apply MI skills more to patients in the preparation stage (P < 0.05) than during the other stages of change. PNs adjusted three MI skills and one generic communication skill to patients' SOC. This explorative study suggests that, at least to some extent, PNs intuitively assess the stage of patients' readiness to change and tailor their communication accordingly. However, differences between the stages were small. By teaching PNs to explicitly identify patients' SOC they could further enhance and adapt their MI and general communication skills to the individual.

The challenge of integrating self-management support into clinical settings

Best practice diabetes mellitus clinical treatment and education takes place in the medical clinic, however, patient outcomes are largely mediated through their own behaviour and lifestyle that occurs after they leave the clinical setting. Once they return home, people usually continue to engage in the social, cultural and lifestyle behaviours that had contributed to having diabetes in the first place. Although a host of factors (e.g. economic, health care team and system, condition and client-related) can impact a client's capacity to self-manage, there are client, organizational and community level strategies that may partially mitigate these difficulties. To address client behaviour, clinicians are increasingly becoming skilled to incorporate self-management support including behavioural counselling interventions into routine practice. At the organizational level, the operation and structure of the clinical setting may create difficulty for staff to provide self-management support. Sustaining benefits on a day-to-day basis presents an additional challenge. This article will review several common implementation barriers to self-management support and describe strategies and techniques used elsewhere to successfully integrate self-management support as a core care component for persons with diabetes.

Implementation of a community-based secondhand smoke reduction intervention for caregivers of urban children with asthma: process evaluation, successes and challenges

Many children, including those with asthma, remain exposed to secondhand smoke. This manuscript evaluates the process of implementing a secondhand smoke reduction counseling intervention using motivational interviewing (MI) for caregivers of urban children with asthma, including reach, dose delivered, dose received and fidelity. Challenges, strategies and successes in applying MI are highlighted. Data for 140 children (3-10 years) enrolled in the School Based Asthma Therapy trial, randomized to the treatment condition and living with one or more smoker, were analyzed. Summary statistics describe the sample, process measures related to intervention implementation, and primary caregiver (PCG) satisfaction with the intervention. The full intervention was completed by 79% of PCGs, but only 17% of other smoking caregivers. Nearly all (98%) PCGs were satisfied with the care study nurses provided and felt the program might be helpful to others. Despite challenges, this intervention was feasible and well received reaching caregivers who were not actively seeking treatment for smoking cessation or secondhand smoke reduction. Anticipating the strategies required to implement such an intervention may help promote participant engagement and retention to enhance the program's ultimate success.

Nutrition and physical activity guidance practices in general practice: a critical review

OBJECTIVE

The aim of this critical review is to provide insight into the main outcomes of research on communication about nutrition and/or physical activity between GPs and patients for prevention or treatment of overweight and obesity.

METHODS

Relevant studies were identified by a computerized search of multiple electronic databases (MEDLINE, PsycINFO) for all available papers between 1 January 1995 and 1 January 2012. In addition, two independent reviewers judged all studies on ten quality criteria.

RESULTS

In total, 41 studies were retrieved. More studies were found about the guidance of obese patients than of overweight patients. The most common weight guidance practice was discussion of weight. The range of communication strategies for nutrition showed to be more diverse than for physical activity. Twelve studies were considered as high-quality studies, 18 were having medium quality, and 11 were seen as low quality.

CONCLUSION

We reflected on the fact that the content of advice about nutrition and physical activity was quite general. GPs' provision of combined lifestyle advice to overweight and obese patients seems to be rather low.

PRACTICE IMPLICATIONS

Observational research is needed to unravel the quality of the advice given by GPs to overweight and obese patients.

A critical appraisal of motivational interviewing within the field of alcohol misuse

A critical appraisal of the evidence that supports efficacy of the brief intervention, motivational interviewing (MI), within the field of alcohol misuse, was made. In order to undertake this appraisal the author will focus on a review of the concept of MI prior to considering the efficacy for MI within the specific field of alcohol misuse.

Women's preferences for contraceptive counseling and decision making

BACKGROUND

Little is known about what women value in their interactions with family planning providers and in decision making about contraception.

STUDY DESIGN

We conducted semistructured interviews with 42 black, white and Latina patients. Transcripts were coded using modified grounded theory.

RESULTS

While women wanted control over the ultimate selection of a method, most also wanted their provider to participate in the decision-making process in a way that emphasized the women's values and preferences. Women desired an intimate, friend-like relationship with their providers and also wanted to receive comprehensive information about options, particularly about side effects. More black and Spanish-speaking Latinas, as compared to whites and English-speaking Latinas, felt that providers should only share their opinion if it is elicited by a patient or if they make their rationale clear to the patient.

CONCLUSION

While, in the absence of medical contraindications, decision making about contraception has often been conceptualized as a woman's autonomous decision, our data indicate that providers of contraceptive counseling can participate in the decision-making process within limits. Differences in preferences seen by race/ethnicity illustrate one example of the importance of individualizing counseling to match women's preferences.
