How to Measure Motivational Interviewing Fidelity in Randomized Controlled Trials: Practical Recommendations

Assessing motivational interviewing integrity in the Toddler Oral Health Intervention study

OBJECTIVES

The Toddler Oral Health Intervention (TOHI) was launched in 2017 to promote oral health prevention at well-baby clinics, with a focus on parents with children aged 6-48 months. This study aims to evaluate the integrity of motivational interviewing (MI) as one of the core intervention pillars in the TOHI study.

METHODS

The TOHI study was conducted at nine well-baby clinics in the central and southern regions of the Netherlands, with 11 trained oral health coaches (OHCs) delivering a tailored individual counselling programme. Audio recordings of counselling sessions were uploaded by the OHCs into an online portal for feedback and integrity evaluation purposes. A trained independent assessor evaluated MI integrity using the MITI 4.2.1 coding scale. IBM SPSS Statistics was used to analyse the data, with ratings on technical and relational components and behavior counts computed by adding up the scores and categorizing them into six key MI skills. Descriptive statistics, including frequencies, percentages and median scores with interquartile ranges, were calculated.

RESULTS

The median ratings on the technical and relational components were 2.5 (IQR 2.0-3.5) and 3.5 (IQR 3.0-4.0) out of a maximum of 5, with 45% and 58% of recordings showing fair or good MI integrity, respectively. A median of 38% (IQR 25-55%) of complex reflections and a reflection-to-question ratio of 0.7 (IQR 0.4-1.0), with 47% and 24% of recordings showing fair or good MI integrity, respectively. Median counts of MI-adherent and non-adherent statements were 3.0 (IQR 2.0-5.0) and 0.0 (IQR 0.0-1.0), respectively. The duration of recordings and MI integrity varied among oral health coaches.

CONCLUSION

Overall, this study revealed that, while intensive training was provided, not all OHCs in the TOHI study met fair thresholds for MI integrity. These findings emphasize the necessity of ongoing training, reflection and support to achieve and maintain a fair or good level of MI integrity in clinical practice.

Combined Motivational Interviewing and Ecological Momentary Intervention to Reduce Hazardous Alcohol Use Among Sexual Minority Cisgender Men and Transgender Individuals: Protocol for a Randomized Controlled Trial

BACKGROUND

Sexual minority cisgender men and transgender (SMMT) individuals, particularly emerging adults (aged 18-34 years), often report hazardous drinking. Given that alcohol use increases the likelihood of HIV risk behaviors, and HIV disproportionately affects SMMT individuals, there is a need to test interventions that reduce hazardous alcohol use and subsequent HIV risk behaviors among this population. Ecological momentary interventions (EMIs), which use mobile phones to deliver risk reduction messages based on current location and behaviors, can help to address triggers that lead to drinking in real time.

OBJECTIVE

This study will test an EMI that uses motivational interviewing (MI), smartphone surveys, mobile breathalyzers, and location tracking to provide real-time messaging that addresses triggers for drinking when SMMT individuals visit locations associated with hazardous alcohol use. In addition, the intervention will deliver harm reduction messaging if individuals report engaging in alcohol use.

METHODS

We will conduct a 3-arm randomized controlled trial (N=405 HIV-negative SMMT individuals; n=135, 33% per arm) comparing the following conditions: (1) Tracking and Reducing Alcohol Consumption (a smartphone-delivered 4-session MI intervention), (2) Tracking and Reducing Alcohol Consumption and Environmental Risk (an EMI combining MI with real-time messaging based on geographic locations that are triggers to drinking), and (3) a smartphone-based alcohol monitoring-only control group. Breathalyzer results and daily self-reports will be used to assess the primary and secondary outcomes of drinking days, drinks per drinking day, binge drinking episodes, and HIV risk behaviors. Additional assessments at baseline, 3 months, 6 months, and 9 months will evaluate exploratory long-term outcomes.

RESULTS

The study is part of a 5-year research project funded in August 2022 by the National Institute on Alcohol Abuse and Alcoholism. The first 1.5 years of the study will be dedicated to planning and development activities, including formative research, app design and testing, and message design and testing. The subsequent 3.5 years will see the study complete participant recruitment, data collection, analyses, report writing, and dissemination. We expect to complete all study data collection in or before January 2027.

CONCLUSIONS

This study will provide novel evidence about the relative efficacy of using a smartphone-delivered MI intervention and real-time messaging to address triggers for hazardous alcohol use and sexual risk behaviors. The EMI approach, which incorporates location-based preventive messaging and behavior surveys, may help to better understand the complexity of daily stressors among SMMT individuals and their impact on hazardous alcohol use and HIV risk behaviors. The tailoring of this intervention toward SMMT individuals helps to address their underrepresentation in existing alcohol use research and will be promising for informing where structural alcohol use prevention and treatment interventions are needed to support SMMT individuals.

Mixed-method evaluation of fidelity of motivational interviewing-based coaching in 5Minutes4Myself Wellness Program for caregivers of children with autism

Objective

This mixed method analysis examined fidelity of the motivational interviewing (MI) delivered during the 5Minutes4Myself wellness program for caregivers of children with Autism Spectrum Disorders.

Methods

Coaches used a manualized MI-approach to collaboratively design participants' individualized wellness programs, and then used it in monthly coaching sessions to support goal pursuit. Audio-recorded consultations and post-participation focus groups were transcribed verbatim. Consultation transcripts were rated for MI adherence using Motivational Interviewing Treatment Integrity Code. Focus group data was coded by the team to identify conceptual categories.

Results

Eighty-seven percent of consultations achieved a beginning (competent) level expert-derived MI standard. Caregivers noted that coaches' MI approach evoked deep emotions and understandings about their lives related to wellness goals, allowed for a permissive flexibility in goal pursuit, and fostered supportive accountability.

Conclusion

MI was used with high levels of fidelity. Participants described the MI approach as more productive, precise, and useful in addressing their needs compared to other available interventions.

Incorporating technology in research with older bereaved adults: Lessons learned from conducting an internet-based randomized controlled trial

Objective

Digital health interventions (DHI) involve multiple interactions between the user, technology platform, and study team, posing challenges for implementation. This paper describes the lessons learned while implementing an internet-based randomized controlled trial (RCT) for reducing depression symptom burden in older acutely-bereaved adults.

Methods

The RCT was entitled "Widowed Elders' Lifestyle after Loss" (or WELL), which compared the efficacy of a DHI to an enhanced usual care (EUC) for reducing depression symptoms in adults 60+ years who lost their spouse/life partner within the previous 12 months. Participants randomized to the DHI used their own tablet, smartphone, or pc to record the timing and regularity of sleep, meals, and physical activity twice daily, for 12 weeks. The also received weekly health coaching sessions from a clinician certified in motivational interviewing. Participants randomized to the EUC arm received weekly calls from research staff and were assessed on the same schedule as intervention participants. All study procedures were conducted virtually. Methodological and procedural challenges were discussed weekly with study staff and the primary investigator.

Results

Many challenges can be categorized as follows recruiting virtually, obtaining informed consent, training older adults to use technology, and establishing rapport with older adults. Solutions required researcher and interventionist flexibility in adapting to new strategies. For instance, we redesigned the informed consent process to include a user-friendly brochure that enhanced participants' understanding of the RCT and improved our enrollment rate. We also utilized user-engagement in refining an intervention protocol.

Conclusion

We resolved implementation challenges without compromising internal validity via interdisciplinary collaborations with mobile programmers to ensure our technology met the unique and varied needs of aging users. The solutions from this study may promote the recruitment and retainment of older adults in research studies that use technology-based interventions.

Health Professionals can Sustain Proficiency in Motivational Interviewing With a Moderate Amount of Training: An Intervention Fidelity Study

INTRODUCTION

Motivational interviewing (MI) proficiency may erode quickly, limiting its effectiveness. We examined whether health professionals completing a 2-day workshop, with 3 to 5 hours of personalized coaching, and twice-yearly group reflections sustained proficiency for the duration of a hip fracture rehabilitation trial and whether intervention was implemented as intended.

METHODS

A fidelity study was completed as part of a process evaluation of the trial that tested whether physical activity increased among hip fracture patients randomly allocated to receive MI (experimental) compared with dietary advice (control) over ten 30-minute sessions. Twelve health professionals (none were proficient in MI before trial commencement) delivered the intervention for up to 952 days. Two hundred experimental sessions (24% of all sessions, 83 patients) were randomly selected to evaluate proficiency using the MI Treatment Integrity scale; along with 20 control sessions delivered by four dietitians. Linear mixed-effects regression analyses determined whether proficiency was sustained over time. Dose was assessed from all experimental sessions ( n = 840, 98 patients).

RESULTS

Intervention was implemented as intended; 82% of patients received at least eight 30-minute sessions. All motivational interviewers were proficient, whereas dietitians did not inadvertently deliver MI. Time had no effect on MI proficiency (est < 0.001/d, P = .913, 95% CI, -0.001 to 0.001).

DISCUSSION

MI proficiency was sustained in a large trial over 2.6 years by completing a 2-day workshop, 3 to 5 hours of personalized coaching, and twice-yearly group reflections, even for those without previous experience; further research needs to establish the maximum duration of training effectiveness.

Use of Motivational Interviewing in Older Patients with Multiple Chronic Conditions and Their Informal Caregivers: A Scoping Review

The use of motivational interviewing is relatively new in multiple chronic conditions (MCCs). A scoping review was conducted according to JBI methodology to identify, map and synthesize existing evidence on the use of motivational interviewing to support self-care behavior changes in older patients with MCCs and to support their informal caregivers in promoting patient self-care changes. Seven databases were searched, from database inception to July 2022, for studies that used motivational interviewing in interventions for older patients with MCCs and their informal caregivers. We identified 12 studies, reported in 15 articles, using qualitative, quantitative, or mixed-method designs, conducted between 2012 and 2022, describing the use of motivational interviewing for patients with MCCs. We could not locate any study regarding its application for informal caregivers. The scoping review showed that the use of motivational interviewing is still limited in MCCs. It was used mainly to improve patient medication adherence. The studies provided scant information about how the method was applied. Future studies should provide more information about the application of motivational interviewing and should address self-care behavior changes relevant to patients and healthcare providers. Informal caregivers should also be targeted in motivational interviewing interventions, as they are essential for the care of older patients with MCCs.

Designing Practical Motivational Interviewing Training for Mental Health Practitioners Implementing Behavioral Lifestyle Interventions: Protocol for 3 Pilot Intervention Studies

BACKGROUND

Motivational interviewing (MI) is an evidence-based, patient-centered communication method shown to be effective in helping persons with serious mental illness (SMI) to improve health behaviors. In clinical trials where study staff conducted lifestyle interventions incorporating an MI approach, cardiovascular disease (CVD) risk profiles of participants with SMI showed improvement. Given the disproportionate burden of CVD in this population, practitioners who provide somatic and mental health care to persons with SMI are ideally positioned to deliver patient-centered CVD risk reduction interventions. However, the time for MI training (traditionally 16-24 hours), follow-up feedback, and the coaching required to develop and maintain patient-centered skills are significant barriers to incorporating MI when scaling up these evidence-based practices.

OBJECTIVE

We describe the design and development of the following 2 scalable MI training approaches for community mental health practitioners: real-time brief workshops and follow-up asynchronous avatar training. These approaches are being used in 3 different pilot implementation research projects that address weight loss, smoking cessation, and CVD risk reduction in people with SMI who are a part of ALACRITY Center, a research-to-practice translation center funded by the National Institute of Mental Health.

METHODS

Clinicians and staff in community mental health clinics across Maryland were trained to deliver 3 distinct evidence-based physical health lifestyle interventions using an MI approach to persons with SMI. The real-time brief MI workshop training for ACHIEVE-D weight loss coaches was 4 hours; IMPACT smoking cessation counselors received 2-hour workshops and prescribers received 1-hour workshops; and RHYTHM CVD risk reduction program staff received 4 hours of MI. All workshop trainings occurred over videoconference. The asynchronous avatar training includes 1 common didactic instructional module for the 3 projects and 1 conversation simulation unique to each study's target behavior. Avatar training is accessible on a commercial website. We plan to assess practitioners' attitudes and beliefs about MI and evaluate the impact of the 2 MI training approaches on their MI skills 3, 6, and 12 months after training using the MI Treatment Integrity 4.2.1 coding tool and the data generated by the avatar-automated scoring system.

RESULTS

The ALACRITY Center was funded in August 2018. We have implemented the MI training for 126 practitioners who are currently delivering the 3 implementation projects. We expect the studies to be complete in May 2023.

CONCLUSIONS

This study will contribute to knowledge about the effect of brief real-time training augmented with avatar skills practice on clinician MI skills. If MI Treatment Integrity scoring shows it to be effective, brief videoconference trainings supplemented with avatar skills practice could be used to train busy community mental health practitioners to use an MI approach when implementing physical health interventions.

LOFIT (Lifestyle front Office For Integrating lifestyle medicine in the Treatment of patients): a novel care model towards community-based options for lifestyle change-study protocol

BACKGROUND

A healthy lifestyle is indispensable for the prevention of noncommunicable diseases. However, lifestyle medicine is hampered by time constraints and competing priorities of treating physicians. A dedicated lifestyle front office (LFO) in secondary/tertiary care may provide an important contribution to optimize patient-centred lifestyle care and connect to lifestyle initiatives from the community. The LOFIT study aims to gain insight into the (cost-)effectiveness of the LFO.

METHODS

Two parallel pragmatic randomized controlled trials will be conducted for (cardio)vascular disorders (i.e. (at risk of) (cardio)vascular disease, diabetes) and musculoskeletal disorders (i.e. osteoarthritis, hip or knee prosthesis). Patients from three outpatient clinics in the Netherlands will be invited to participate in the study. Inclusion criteria are body mass index (BMI) ≥25 (kg/m2) and/or smoking. Participants will be randomly allocated to either the intervention group or a usual care control group. In total, we aim to include 552 patients, 276 in each trial divided over both treatment arms. Patients allocated to the intervention group will participate in a face-to-face motivational interviewing (MI) coaching session with a so-called lifestyle broker. The patient will be supported and guided towards suitable community-based lifestyle initiatives. A network communication platform will be used to communicate between the lifestyle broker, patient, referred community-based lifestyle initiative and/or other relevant stakeholders (e.g. general practitioner). The primary outcome measure is the adapted Fuster-BEWAT, a composite health risk and lifestyle score consisting of resting systolic and diastolic blood pressure, objectively measured physical activity and sitting time, BMI, fruit and vegetable consumption and smoking behaviour. Secondary outcomes include cardiometabolic markers, anthropometrics, health behaviours, psychological factors, patient-reported outcome measures (PROMs), cost-effectiveness measures and a mixed-method process evaluation. Data collection will be conducted at baseline, 3, 6, 9 and 12 months follow-up.

DISCUSSION

This study will gain insight into the (cost-)effectiveness of a novel care model in which patients under treatment in secondary or tertiary care are referred to community-based lifestyle initiatives to change their lifestyle.

Intervention Fidelity of Telephone Motivational Interviewing On Physical Activity, Fruit Intake, and Vegetable Consumption in Dutch Outpatients With and Without Hypertension

BACKGROUND

In theory, Motivational Interviewing (MI) fidelity should be associated with client outcomes. Nevertheless, this fidelity-effectiveness association is rarely investigated. This study evaluated the extent to which Telephone Motivational Interviewing (TMI) fidelity is associated with change in self-reported physical activity (PA), fruit intake, and vegetable consumption.

METHOD

Adults in primary care (45-70 years) participated in a study that compared the effect of tailor print communication, telephone motivational interviewing (TMI), and a combination of the two on PA, fruit intake, and vegetable consumption. MI fidelity was assessed using the behavioral coding method "Motivational Interviewing Treatment Integrity Code (MITI)" in 409 randomly selected audio-recorded sessions, representing 232 participants of the TMI group. The associations between MI fidelity scores and the behavioral changes from baseline to 47-week follow-up were examined using backward multiple linear regression analyses (adjusted for covariates).

RESULTS

A significant and positive association between the percentage of MI adherent responses and improvements in PA and fruit consumption was found with respectively a small and medium effect size. The global rating "Spirit" (which resembles an all-at-once appraisal of the interviewer's MI competence) was significantly, but inversely associated with progress in vegetable intake with a medium effect size.

CONCLUSION

The finding that relatively lower MI competency was associated with higher vegetable consumption went against our expectations. Findings suggest that practicing MI-consistent skills was beneficial in promoting PA and fruit consumption, but moderated vegetable intake. This study contributes to the scientific confidence that TMI enables change in PA and fruit intake.

Feasibility, acceptability, and fidelity of Physical Activity Routines After Stroke (PARAS): a multifaceted behaviour change intervention targeting free-living physical activity and sedentary behaviour in community-dwelling adult stroke survivors

BACKGROUND

Low levels of habitual physical activity and high levels of sedentary behaviour are commonly observed post-stroke. We aimed to assess the feasibility, acceptability and fidelity of a multifaceted, theory- and evidence-informed supported self-management intervention targeting physical activity and sedentary behaviour after stroke: Physical Activity Routines After Stroke (PARAS).

METHODS

Adult stroke survivors and healthcare professionals were recruited from North East England stroke services. Stroke survivor physical activity and sedentary behaviour were targeted by a self-management behavioural intervention supported by healthcare professionals trained in intervention delivery. The main outcomes were protocol and intervention acceptability and feasibility and fidelity of intervention delivery.

RESULTS

Eleven healthcare professionals (9 physiotherapists; 2 occupational therapists) participated in the study. Stroke survivor recruitment was lower than anticipated (19 versus target of up to 35). The healthcare professional training programme was feasible, with fidelity assessment of delivery supporting this finding. Data completeness was acceptable according to a priori criteria (>60%), except for stroke survivor questionnaire return rate (59%) and interview uptake (52%). No serious adverse events occurred. Healthcare professionals and stroke survivors perceived intervention delivery to be feasible and acceptable with minor modifications highlighted including the potential for earlier delivery in the stroke pathway.

CONCLUSIONS

The study protocol and intervention delivery were feasible and acceptable to stroke survivors and healthcare professionals with modifications required before large-scale evaluation.

Attitudes and experiences towards the application of motivational interviewing by podiatrists working with people with diabetes at high-risk of developing foot ulcers: a mixed-methods study

Background

Podiatrists are key professionals in promoting adequate foot self-care for people with diabetes at high-risk of developing foot ulcers. However, merely informing patients about the advantages of foot self-care is insufficient to realise behavioural change. Motivational interviewing (MI) is a promising person-centred communication style that could help to create a working alliance between healthcare providers and patient to improve foot self-care. This study aims to observe and analyse the application of MI in consultations carried out by MI-trained and non-MI-trained podiatrists with their patients, and explore podiatrists’ attitudes and experiences towards MI.

Methods

Eighteen podiatrists (median age: 28.5 years, 10 female and 8 male) followed a three-day basic training in MI and 4 podiatrists (median age: 38.5 years, 4 female) were not trained in MI. To observe and rate the MI-fidelity in daily clinical practice, audio recordings from the MI-trained and non-MI-trained podiatrists were scored with the Motivational Interviewing Treatment Integrity code. Individual, semi-structed, in-depth interviews were conducted with the MI-trained podiatrists to explore their attitudes towards and experiences with MI. These data sources were triangulated to describe the effect of training podiatrists in MI for their clinical practice.

Results

The MI-trained podiatrists scored significantly higher than the non-MI-trained podiatrists on two of four global MI-related communication skills (empathy, p = 0.008 and change talk, p = 0.008), on one of five core MI-adherent behaviours (affirmation, p = 0.041) and on one of the other behaviour counts (simple reflections, p = 0.008). The podiatrists mainly reported their attitudes and experiences regarding partnership and cultivating change talk, during the interviews. In addition, they also mentioned facilitators and barriers to using MI and indicated whether they experienced MI as having added value.

Conclusions

The MI-trained podiatrists used the principles of MI at a solid beginner proficiency level in their clinical practice in comparison to the non-MI-trained podiatrists, who did not reach this level. This achievement is in accordance with the basic MI-training they received. This multi-method study reveals that podiatrists can be effectively trained in applying MI in daily clinical practice.

Practice nurses' communication with people living with type 2 diabetes: A scoping review

OBJECTIVE

To identify the key characteristics of practice nurses' communication with people living with Type 2 Diabetes (T2D) where lifestyle activities are discussed.

METHODS

A scoping review of the peer-reviewed literature was conducted. Reflexive thematic analysis was used to identify key themes that emerged. The PRISMA-ScR checklist was followed.

RESULTS

25 studies were retained in the final review. Nurses who were committed to engaging in lifestyle discussions created supportive environments and built rapport to enable change conversations. However, this was present in just 20% of the studies. In most studies, (60%) nurses continued to use traditional health education communication styles, had little understanding of behaviour change theories, lacked skills in behaviour change counselling and were reluctant to engage in behaviour change discussions with people with T2D .

CONCLUSIONS

Nurses require a deeper understanding of behavioural change theories and skills in behavioural counselling.

PRACTICE IMPLICATIONS

Practice nurses have a unique opportunity to facilitate T2D remission by engaging in evidence-based behaviour change communication. A behaviour change training intervention is needed that recognises the environment of practice nurse consultations. It needs to be pragmatic and fully consider the enablers and barriers to addressing behaviour change in both the nurse and the person with T2D.

The Status of SBIRT Training in Health Professions Education: A Cross-Discipline Review and Evaluation of SBIRT Curricula and Educational Research

PURPOSE

To assess the quality of curricular research on the Screening Brief Intervention and Referral to Treatment (SBIRT) approach and determine the presence of useful training modalities, particularly motivational interviewing (MI) training, across health care training curricula.

METHOD

The authors conducted a systematic review of published, peer-reviewed studies in PubMed, ERIC, CINAHL, Ovid HealthSTAR, and PsycINFO databases through March 2021 for English-language studies describing SBIRT, a curriculum for health care trainees, and curricular intervention outcomes. After the records were independently assessed, data were extracted and 20% of the studies were double-coded for interrater reliability.

RESULTS

Of 1,856 studies, 95 were included in the review; 22 had overlapping samples and were consolidated into 10 nested studies, leaving 83 total. Interrater reliability ranged from moderate (κ = .74, P < .001) to strong (κ = .91, P < .001) agreement. SBIRT training was delivered to trainees across many professions, including nursing (n = 34, 41%), medical residency (n = 28, 34%), and social work (n = 24, 29%). Nearly every study described SBIRT training methods (n = 80, 96%), and most reported training in MI (n = 54, 65%). On average, studies reported 4.06 (SD = 1.64) different SBIRT training methods and 3.31 (SD = 1.59) MI training methods. Their mean design score was 1.92 (SD = 0.84) and mean measurement score was 1.89 (SD = 1.05). A minority of studies measured SBIRT/MI skill (n = 23, 28%), and 4 studies (5%) set a priori benchmarks for their curricula.

CONCLUSIONS

SBIRT training has been delivered to a wide range of health care trainees and often includes MI. Rigor scores for the studies were generally low due to limited research designs and infrequent use of objective skill measurement. Future work should include predefined training benchmarks and validated skills measurement.

Training Providers in Motivational Interviewing to Promote Behavior Change

Motivational Interviewing (MI) is a highly specified behavior change communication approach to improve patient-provider relationships, provider communication, and patient health outcomes. Because MI is built on a foundation of patient autonomy support, a feature known to positively influence behavior change during adolescence and emerging adulthood, MI is an evidence-based framework that can inform interventions targeting improvements in health outcomes among youth. MI can be difficult to implement with adequate fidelity, because learning MI requires time and commitment from busy providers with competing priorities. This review addresses best practices for implementing MI within adolescent serving medical settings (eg, pediatrics, family practices, rural health clinics, community health organizations, and so forth), including an orientation to MI, examples of efficacious interventions that were developed leveraging MI, and consideration for the design of training programs that include ongoing support to maximize the likelihood of sustainment.

Comparing process evaluations of motivational interviewing interventions for managing health conditions and health promotions: A scoping review

OBJECTIVE

To explore how process evaluations were conducted alongside randomised controlled trials (RCTs) involving motivational interviewing (MI) as an intervention to manage health conditions.

METHODS

A scoping review was conducted. We searched 7 databases (to May 2021) for studies that incorporated at least one aspect of process evaluation of RCTs using MI to manage a health condition. Two reviewers screened the studies for eligibility and extracted data according to Medical Research Council framework.

RESULTS

Of the 123 studies included, 85% lacked a theoretical framework for process evaluation. Most studies reported fidelity, but dose was underreported. Sixty-five studies reported mechanism of impact, but only twelve used participant experiences to understand how MI works. Only thirty used true mediation analysis. Context (n = 33) was the least reported aspect of process evaluation.

CONCLUSION

Process evaluations of MI to manage health conditions often consist of fragmented reports of implementation, mechanisms, and context. Using validated measures of fidelity, reporting dose, and using mediation analysis alongside qualitative exploration of participant and stakeholder insights will improve our understanding of how MI works.

PRACTICE IMPLICATIONS

Robust and comprehensive process evaluations will inform MI researchers to design more rigorous trials and for clinicians to implement more effective interventions for their clients.

The case for prioritizing implementation strategy fidelity measurement: benefits and challenges

Implementation strategies are systematic approaches to improve the uptake and sustainability of evidence-based interventions. They frequently focus on changing provider behavior through the provision of interventions such as training, coaching, and audit-and-feedback. Implementation strategies often impact intermediate behavioral outcomes like provider guideline adherence, in turn improving patient outcomes. Fidelity of implementation strategy delivery is defined as the extent to which an implementation strategy is carried out as it was designed. Implementation strategy fidelity measurement is under-developed and under-reported, with the quality of reporting decreasing over time. Benefits of fidelity measurement include the exploration of the extent to which observed effects are moderated by fidelity, and critical information about Type-III research errors, or the likelihood that null findings result from implementation strategy fidelity failure. Reviews of implementation strategy efficacy often report wide variation across studies, commonly calling for increased implementation strategy fidelity measurement to help explain variations. Despite the methodological benefits of rigorous fidelity measurement, implementation researchers face multi-level challenges and complexities. Challenges include the measurement of a complex variable, multiple data collection modalities with varying precision and costs, and the need for fidelity measurement to change in-step with adaptations. In this position paper, we weigh these costs and benefits and ultimately contend that implementation strategy fidelity measurement and reporting should be improved in trials of implementation strategies. We offer pragmatic solutions for researchers to make immediate improvements like the use of mixed methods or innovative data collection and analysis techniques, the inclusion of implementation strategy fidelity assessment in reporting guidelines, and the staged development of fidelity tools across the evolution of an implementation strategy. We also call for additional research into the barriers and facilitators of implementation strategy fidelity measurement to further clarify the best path forward.

Augmenting an online self-directed intervention for gambling disorder with a single motivational interview: study protocol for a randomized controlled trial

BACKGROUND

Despite the success of gold standard cognitive-behavioral therapy for problem and disordered gambling, the majority of individuals with gambling problems do not seek or receive professional treatment. Thus, the development of less intrusive self-directed interventions has been encouraged. Bibliotherapy for problem gambling has shown promise, both alone and in combination with motivational interviews, but there is still a lack of online self-directed intervention research. The current randomized controlled trial proposes to assess the additive benefit of a single digital motivational interview delivered in conjunction with an online self-directed treatment program for problem gambling and gambling disorder.

METHODS

A two-arm randomized controlled trial will be conducted, wherein eligible participants (N=270) will be recruited across Canada via internet advertisements posted to several platforms. All participants will receive access to an online self-directed gambling intervention program. Participants will be randomly assigned to either complete the online program alone or receive a digital motivational interview, conducted through an online audioconferencing platform (i.e., Microsoft Teams) to supplement the online program. The primary outcomes of gambling severity, frequency, and expenditures will be tracked along with secondary outcomes (i.e., depression, anxiety, general distress, alcohol use, and online program user data) over a 24-month period. It is expected that participants in both groups will experience a reduction in symptoms across the board, but more substantial improvements will be observed in the group that receives a supplemental motivational interview.

DISCUSSION

The results of this trial will expand upon prior gambling intervention research by informing best practices for the provision of online self-help for problem gambling.

Impact of Motivational Interviewing on Parental Risk-Related Behaviors and Knowledge of Early Childhood Caries: A Systematic Review

BACKGROUND

Behavior is important in dental disease etiology, so behavioral interventions are needed for prevention and treatment. Motivational interviewing (MI) has been proposed as a potentially useful behavioral intervention for prevention of early childhood caries.

METHODS

Studies have evaluated the effectiveness of MI on reduction of the risk-related behaviors for early childhood caries (ECC) compared to dental health education (DHE) The aim of this systematic review was to assess the scientific evidence on MI applied to change parental risk-related behaviors. The potentially eligible studies involved the assessment of caries-related behaviors in caregivers receiving MI. Electronic search of English published literature was performed in February 2020 in the Scopus, Cochrane, PubMed, and Embase databases. Assessment of risk of bias was done by the Cochrane risk of bias tool.

RESULTS

Of 329 articles retrieved initially, seven were eligible for inclusion in this review. Four studies evaluated the behavior of tooth brushing and four studies assessed the cariogenic feeding practice, while only one study investigated the behavior of checking teeth for pre-cavities. Moreover, two studies examined dental attendance for varnish fluoride use and oral health-related knowledge. It was not possible to perform a meta-analysis.

CONCLUSIONS

Generally, results support the application of MI to improve the "dental attendance behavior for fluoride use" and participants' knowledge. However, the results were inconclusive for other behaviors. We need further and better designed interventions to completely evaluate the impact of MI on specific ECC-related behaviors.

Barriers and Facilitators for Implementing Motivational Interviewing as a Return to Work Intervention in a Norwegian Social Insurance Setting: A Mixed Methods Process Evaluation

Purpose The aim of this study was to evaluate potential barriers and facilitators for implementing motivational interviewing (MI) as a return to work (RTW) intervention in a Norwegian social insurance setting. Methods A mixed-methods process evaluation was conducted alongside a randomized controlled trial involving MI sessions delivered by social insurance caseworkers. The study was guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework using focus groups with the caseworkers. MI fidelity was evaluated through audio-recordings of MI sessions and questionnaires to sick-listed participants. Results Lack of co-worker and managerial support, time and place for practicing to further develop MI skills, and a high workload made the MI intervention challenging for the caseworkers. The MI method was experienced as useful, but difficult to master. MI fidelity results showed technical global scores over the threshold for "beginning proficiency" whereas the relational global score was under the threshold. The sick-listed workers reported being satisfied with the MI sessions. Conclusions Despite caseworker motivation for learning and using MI in early follow-up sessions, MI was hard to master and use in practice. Several barriers and facilitators were identified; these should be addressed before implementing MI in a social insurance setting.Trial registration ClinicalTrials.gov: NCT03212118 (registered July 11, 2017).

Intervention Fidelity Focusing on Interaction between Participants and Facilitators in a Telephone-Delivered Health Coaching Intervention for the Prevention and Management of Type 2 Diabetes

Self-management support and lifestyle interventions with an empowerment approach have been found to be effective strategies for health improvement among people at risk for or living with type 2 diabetes. Telephone coaching seems particularly efficient for individuals with low socioeconomic status and culturally and linguistically diverse backgrounds. In this mixed methods study, we investigate a telephone-delivered health coaching intervention provided by the diabetes project SMART2D (Self-Management Approach and Reciprocal learning for Type 2 Diabetes) implemented in socioeconomically disadvantaged areas in Stockholm, Sweden. We focus on the interaction between participants and facilitators as part of intervention fidelity. Recorded coaching sessions were scored using an interaction tool and analyzed by exploratory factor analysis and recorded supervisory discussions with facilitators analyzed using thematic analysis. The quantitative analysis showed that the intervention components were delivered as intended; however, differences between facilitators were found. The qualitative data highlighted differences between facilitators in the delivery, especially in relation to dietary and physical activity goalsetting. The level of language skills hindered the delivery flow and the tailoring of sessions to participants' needs led to different delivery styles. The interaction between facilitators and participants is an important aspect of intervention implementation. Tailoring of interventions is necessary, and language-skilled facilitators are needed to minimize barriers in intervention delivery.

Fidelity of a Motivational Interviewing Intervention for Improving Return to Work for People with Musculoskeletal Disorders

The objective of this study was to conduct a fidelity evaluation of a motivational interviewing (MI) intervention delivered by social insurance caseworkers, in a three-arm randomized controlled trial (RCT) for improving return to work for people on sick leave with musculoskeletal disorders. The caseworkers received six days of MI training, including an intervention manual prior to the trial onset, as well as supervision throughout the trial. The caseworkers recorded 21 MI sessions at regular intervals during the trial. An independent MI analysis center scored the recordings using the MI treatment integrity code (MITI 4). In addition, three experienced MI trainers assessed the adherence to the MI intervention manual on a 1–4 Likert scale and MI competence. Total MITI 4 mean scores were at beginning proficiency levels for two components (global technical, mean 3.0; SD 0.6 and the reflections/questions ratio, mean 1.1; SD 0.2) and under beginning proficiency for two components (global relational, mean 3.2; SD 0.7 and complex question, mean 34.0; SD 21.2). The MI trainers’ assessment showed similar results. The mean adherence score for the MI sessions was 2.96 (SD 0.9). Despite delivering a thorough course and supervision package, most of the caseworkers did not reach proficiency levels of good MI competence during the study. The fidelity evaluation showed that a large amount of training, supervision and practice is needed for caseworkers to become competent MI providers. When planning to implement MI, it is important that thorough consideration is given regarding the resources and the time needed to train caseworkers to provide MI in a social insurance setting.

Fitness facility staff demonstrate high fidelity when implementing an evidence-based diabetes prevention program

Translating evidence-based diabetes prevention programs into the community is needed to make promising interventions accessible to individuals at-risk of type 2 diabetes. To increase the likelihood of successful translation, implementation evaluations should be conducted to understand program outcomes and provide feedback for future scale-up sites. The purpose of this research was to examine the delivery of, and engagement with, an evidence-based diet and exercise diabetes prevention program when delivered by fitness facility staff within a community organization. Ten staff from a community organization were trained to deliver the diabetes prevention program. Between August 2019-March 2020, 26 clients enrolled in the program and were assigned to one of the ten staff. Three fidelity components were accessed. First, staff completed session-specific fidelity checklists (n = 156). Second, two audio-recorded counseling sessions from all clients underwent an independent coder fidelity check (n = 49). Third, staff recorded client goals on session-specific fidelity checklists and all goals were independently assessed for (a) staff goal-setting fidelity, (b) client intervention receipt, and (c) client goal enactment by two coders (n = 285). Average self-reported fidelity was 90% for all six sessions. Independent coder scores for both counseling sessions were 83% and 81%. Overall staff helped clients create goals in line with program content and had a goal achievement of 78%. The program was implemented with high fidelity by staff at a community organization and clients engaged with the program. Findings increase confidence that program effects are due to the intervention itself and provide feedback to refine implementation strategies to support future scale-up efforts.

Increasing Older Adult Involvement in Geriatric Assessment: A Mixed-Methods Process Evaluation

Objectives: Goal setting and motivational interviewing (MI) may increase well-being by promoting healthy behavior. Since we failed to show improved well-being in a proactive assessment service for community-dwelling older adults applying these techniques, we studied whether implementation processes could explain this. Methods: Goals set during the comprehensive geriatric assessment were evaluated on their potential for behavior change. MI and goal setting adherence wasassessed by reviewing audiotaped interactions and interviewing care professionals. Results: Among the 280 goals set with 230 frail older adults (mean age 77 ± 6.9 years, 59% women), more than 90% had a low potential for behavior change. Quality thresholds for MI were reached in only one of the 11 interactions. Application was hindered by the context and the limited proficiency of care professionals. Discussion: Implementation was suboptimal for goal setting and MI. This decreased the potential for improved well-being in the participating older adults.

Addressing tobacco smoking and drinking to improve TB treatment outcomes, in South Africa: a feasibility study of the ProLife program

Alcohol and tobacco use may lead to negative treatment outcomes in tuberculosis (TB) patients, and even more so if they are HIV-infected. We developed and tested the feasibility of a complex behavioral intervention (ProLife) delivered by lay health workers (LHWs) to improve treatment outcomes in TB patients who smoke tobacco and/or drink alcohol, at nine clinics in South Africa. The intervention comprised three brief motivational interviewing (MI) sessions augmented with a short message service (SMS) program, targeting as appropriate: tobacco smoking, harmful or hazardous drinking and medication adherence. Patients received SMSs twice a week. We measured recruitment and retention rates and assessed fidelity to the MI technique (MI Treatment Integrity 4.1 tool). Finally, we explored LHWs' and patients' experiences through interviews and semi-structured questionnaires, respectively. We screened 137 TB patients and identified 14 smokers, 13 alcohol drinkers, and 18 patients with both behaviors. Participants' mean age was 39.8 years, and 82.2% were men. The fidelity assessments pointed to the LHWs' successful application of key MI skills, but failure to reach MI competency thresholds. Nevertheless, most patients rated the MI sessions as helpful, ascribed positive attributes to their counselors, and reported behavioral changes. SMSs were perceived as reinforcing but difficult language and technical delivery problems were identified as problems. The LHWs' interview responses suggested that they (a) grasped the basic MI spirit but failed to understand specific MI techniques due to insufficient training practice; (b) perceived ProLife as having benefitted the patients (as well as themselves); (c) viewed the SMSs favorably; but (d) considered limited space and privacy at the clinics as key challenges. The ProLife program targeting multiple risk behaviors in TB patients is acceptable but LHW training protocol, and changes in wording and delivery of SMS are necessary to improve the intervention. Trial registration: ISRCTN62728852.

Delivering motivational interviewing early post stroke: standardisation of the intervention

BACKGROUND

We applied Motivational Interviewing (MI) techniques, early after stroke, to facilitate psychological adjustment to life post-stroke. In our trial, MI-plus-usual-care increased the likelihood of normal mood at 3-months post-stroke, compared to usual-care alone. Whilst appropriate training, manuals, and supervision may increase adherence to core principles of this complex intervention, unintended variability in implementation inevitably remains. We aimed to explore the impact of variability on participant outcome.

METHODS

Using our trial data (411 participants), we explored variation in MI delivery, examining: therapist characteristics (stroke care expertise/knowledge, psychology training); MI content (fidelity to MI techniques assessed with Motivational Interviewing Treatment Integrity code, describing therapist behaviours as MI-consistent, MI-neutral or MI-inconsistent); and MI dose (number/duration of sessions).

RESULTS

The four MI therapists (two nurses/two psychologists) had varying expertise and MI delivery. Across therapists, mean average session duration ranged 29.5-47.8 min. The percentage of participants completing the per-protocol four sessions ranged 47%-74%. These variations were not related to participant outcome. There were uniformly high frequencies (>99%) of MI-consistent and MI-neutral interactions, and low frequencies (<1%) of MI-inconsistent interactions.

CONCLUSIONS

Variation in therapist characteristics and MI dose did not affect participant outcome. These may have been tolerated due to high fidelity to MI principles.IMPLICATIONS FOR REHABILITATIONMotivational Interviewing (MI) can help reduce depression in stroke survivors when delivered early after stroke.The effectiveness of our MI intervention depends on the delivery of high quality MI; in particular, interactions with low levels of MI-inconsistency, and high global MI ratings, ideally delivered over more than one session, each lasting at least 30 minutes.Provided high quality MI is being delivered, the intervention can still have a beneficial effect on participant outcome, even with flexibility and variation in therapist characteristics, and duration and number of sessions, which may be inevitable in a clinical context.

A randomized clinical trial of a theory-based fentanyl overdose education and fentanyl test strip distribution intervention to reduce rates of opioid overdose: study protocol for a randomized controlled trial

Background

Opioid overdose deaths involving synthetic opioids, particularly illicitly manufactured fentanyl, remain a substantial public health concern in North America. Responses to overdose events (e.g., administration of naloxone and rescue breathing) are effective at reducing mortality; however, more interventions are needed to prevent overdoses involving illicitly manufactured fentanyl. This study protocol aims to evaluate the effectiveness of a behavior change intervention that incorporates individual counseling, practical training in fentanyl test strip use, and distribution of fentanyl test strips for take-home use among people who use drugs.

Methods

Residents of Rhode Island aged 18–65 years who report recent substance use (including prescription pills obtained from the street; heroin, powder cocaine, crack cocaine, methamphetamine; or any drug by injection) (n = 500) will be recruited through advertisements and targeted street-based outreach into a two-arm randomized clinical trial with 12 months of post-randomization follow-up. Eligible participants will be randomized (1:1) to receive either the RAPIDS intervention (i.e., fentanyl-specific overdose education, behavior change motivational interviewing (MI) sessions focused on using fentanyl test strips to reduce overdose risk, fentanyl test strip training, and distribution of fentanyl test strips for personal use) or standard overdose education as control. Participants will attend MI booster sessions (intervention) or attention-matched control sessions at 1, 2, and 3 months post-randomization. All participants will be offered naloxone at enrolment. The primary outcome is a composite measure of self-reported overdose in the previous month at 6- and/or 12-month follow-up visit. Secondary outcome measures include administratively linked data regarding fatal (post-mortem investigation) and non-fatal (hospitalization or emergency medical service utilization) overdoses.

Discussion

If the RAPIDS intervention is found to be effective, its brief MI and fentanyl test strip training components could be easily incorporated into existing community-based overdose prevention programming to help reduce the rates of fentanyl-related opioid overdose.

A single-case experimental design investigation of collaborative goal setting practices in hospital-based speech-language pathologists when provided supports to use motivational interviewing and goal attainment scaling

The study investigated the impact of the electronic Goal Attainment Scaling (eGAS) process on medical speech-language pathologists' (SLPs) interviewing and goal setting. The process was trained via the eGAS app, designed to facilitate motivational interviewing and goal attainment scaling. The study utilized a single-case, nonconcurrent, multiple-baseline design replicated across three clinicians and their 27 respective clients. We observed client-clinician dyads engaged in setting rehabilitation goals pre and post eGAS training. The clients had neurogenic conditions and were being treated for cognitive, communication and/or swallowing challenges in an outpatient setting. Two measures were used to collect data on the clinician's interviewing and goal-setting behaviors: (1) Assessment of Client-Centeredness when Interviewing and Goal Setting (ACIG) scale, and (2) a task analysis, i.e., the Clinician Interview Behavior scale (CIB). Training with eGAS had a strong effect on clinicians' collaborative interviewing behaviors, an inconsistent effect on their ability to adhere to a three-phase interview structure, and a strong effect on their ability to generate valid goal attainment scales. This study provides preliminary support that the eGAS process provides a feasible framework for training hospital-based SLPs engaged in neurorehabilitation to use collaborative interviewing behaviors and produce valid person-centered rehabilitation goals.

Promoting Hispanic Immigrant Health via Community Health Workers and Motivational Interviewing

Hispanic immigrant health disparities are among the highest in the nation, especially related to obesity and access to health services. Healthy Fit (En Forma Saludable) is a health promotion program that leverages public health department infrastructure to address these disparities through the use of three key innovations explored in this article: community health workers (CHWs), motivational interviewing (MI), and vouchers for free preventative health services. CHWs trained in MI conduct a health screening and then distribute preventive service vouchers and health resources as needed based on screening results. Vouchers cover breast, cervical, and colorectal cancer screening, and several vaccinations including flu and human papillomavirus. Resources to support exercise, to support a healthy diet, to quit smoking, and to reduce risky drinking are also distributed as needed. CHWs then use MI to address perceived barriers and strengthen intrinsic motivation to make use of the health resources. Integrating these strategies provides a low-cost approach to promote healthy behavior in an underserved immigrant population.

Fidelity of Motivational Interviewing in School-Based Intervention and Research

Educational researchers and school-based practitioners are increasingly infusing motivational interviewing (MI) into new and existing intervention protocols to provide support to students, parents, teachers, and school administrators. To date, however, the majority of the research in this area has focused on feasibility of implementation rather than fidelity of implementation. In this manuscript, we will present MI fidelity data from 245 audio-recorded conversations with 113 unique caregivers and 20 coaches, who implemented a school-based, positive parenting intervention. The aggregate fidelity scores across coaches, parents, and sessions provide evidence the training and support procedures were effective in assisting school-based personnel to implement MI with reasonable levels of fidelity in practice settings. Further, results suggest that MI fidelity varied between sessions and coaches and that within-coach variation (e.g., session-level variation in the quality of MI delivered) greatly exceeded between-coach variation. Implications for practice and future research are discussed.

Impact of motivational interviewing on early childhood caries: A systematic review and meta-analysis

BACKGROUND

The authors aimed to assess the scientific evidence on motivational interviewing for the clinical reduction of early childhood caries compared with traditional dental health education.

METHODS

Search terms were selected on the basis of Medical Subject Headings and non-Medical Subject Headings terms. The main key words were motivational interviewing, early childhood caries, and education. Potentially eligible studies involved the clinical assessment of caries rate in children whose parents or caregivers received motivational interviewing as an intervention. The authors assessed the risk of bias using the Cochrane risk-of-bias tool. In March 2019, the authors performed an electronic database search of literature published in English within the following databases: Scopus, Cochrane, PubMed, and Embase.

RESULTS

Of 329 articles retrieved initially, 14 were eligible for inclusion in the systematic review and 3 articles contributed to the meta-analysis. For statistical analysis, the mean difference of continuous data was analyzed at a 95% confidence interval using the random-effects model.

CONCLUSIONS

Overall, the evidence presented in this review was limited. Although the results of the meta-analysis showed that motivational interviewing is as effective as dental health education in controlling early childhood caries, we need more and better designed and reported interventions to assess its impact on early childhood caries accurately.

Rationale, design and study protocol of the 'Strong Families Start at Home' feasibility trial to improve the diet quality of low-income, ethnically diverse children by helping parents improve their feeding and food preparation practices

There is an urgent need to create effective interventions that help parents establish a healthy diet among their children early in life, especially among low-income and ethnically and racially diverse families. U.S. children eat too few fruits, vegetables and whole grains, and too many energy dense foods, dietary behaviors associated with increased morbidity from chronic diseases. Parents play a key role in shaping children's diets. Best practices suggest that parents should involve children in food preparation, and offer, encourage and model eating a variety of healthy foods. In addition, while parents help to shape food preferences, not all children respond in the same way. Certain child appetitive traits, such as satiety responsiveness (sensitivity to internal satiety signals), food responsiveness (sensitivity to external food cues), and food fussiness may help explain some of these differences. Prior interventions to improve the diet of preschool children have not used a holistic approach that targets the home food environment, by focusing on food quality, food preparation, and positive feeding practices while also acknowledging a child's appetitive traits. This manuscript describes the rationale and design for a 6-month pilot randomized controlled trial, Strong Families Start at Home, that randomizes parents and their 2-to 5-year old children to either a home-based environmental dietary intervention or an attention-control group. The primary aim of the study is to explore the feasibility and acceptability of the intervention and evaluation and to determine the intervention's preliminary efficacy on child diet quality, feeding practices, and availability of healthy foods in the home.

Efficacy of a physical activity programme combining individualized aerobic exercise and coaching to improve physical fitness in neuromuscular diseases (I'M FINE): study protocol of a randomized controlled trial

Background

In individuals with neuromuscular diseases (NMD), symptoms of muscle weakness, fatigue and pain may limit physical activity. Inactivity leads to reduced physical fitness, which further complicates daily life functioning. Due to inconclusive evidence regarding exercise in NMD, the optimal training approach and strategies to preserve an active lifestyle remain to be determined. The physical activity programme I’M FINE, consisting of individualized aerobic exercise to improve physical fitness and coaching to preserve an active lifestyle, was therefore developed. The primary objective of this study will be to evaluate the efficacy of the I’M FINE programme in terms of improved physical fitness in individuals with slowly progressive NMD, compared to usual care.

Methods

A multicentre, assessor-blinded, two armed, randomized controlled trial will be conducted in a sample of 90 individuals with slowly progressive NMD. Participants motivated to improve their reduced physical fitness will be randomized (ratio 1:1) to the I’M FINE intervention or usual care. The I’M FINE intervention consists of a six-month physical activity programme, including individualized home-based aerobic exercise to improve physical fitness (i.e. peak oxygen uptake), and motivational interviewing coaching (e.g. goal setting, self-management) to adopt and preserve an active lifestyle. Measurements will be performed at baseline, post-intervention, and at 12- and 18-months follow-up. The primary outcome is peak oxygen uptake (VO₂ peak) directly post intervention. Main secondary outcomes are physical capacity, muscle strength, self-efficacy, daily activity, quality of life and markers of metabolic syndrome. The primary analysis compares change in VO₂ peak post-intervention between the intervention and usual care group, with analysis of covariance.

Discussion

The I’M FINE study will provide evidence regarding the efficacy of a physical activity intervention on the physical fitness and active lifestyle over the short- and long-term in individuals with slowly progressive NMD. These outcomes could potentially improve the (inter)national guidelines for efficacy of aerobic exercise programmes and provide insight in achieving a more active lifestyle in NMD.

A brief motivational intervention for enhancing medication adherence for adolescents with bipolar disorder: A pilot randomized trial

BACKGROUND

Youth with bipolar disorder (BP) exhibit poor medication adherence, contributing to affective recurrence. Brief Motivational Interventions (BMIs) improve adherence among adolescents with chronic conditions.

METHODS

In an open pilot series, we developed a 3-session BMI for BP adolescents targeting medication adherence and conducted a pilot randomized trial comparing Standard Care (SC) versus SC+BMI. Participants include 43 adolescents with BP prescribed psychotropic medications. We assessed medication adherence objectively via bluetooth-enabled electronic pillbox (MedTracker). A blinded evaluator assessed mood symptoms at intake, 3- and 6-months.

RESULTS

The BMI was well-received. Average objective medication adherence increased with time in SC+BMI, but decreased in SC-Alone (p < 0.0001). Adolescents' baseline self-rated expectation of improvement with treatment moderated the effect of treatment on improvement in adherence over time (p = 0.003). Across groups, poor adherence predicted increased likelihood of depression and hypo/mania symptoms in the subsequent two weeks; medication adherence mediated the effect of the BMI on the likelihood of depressive symptoms (p = 0.007).

LIMITATIONS

Electronic pillbox use (across groups) may enhance adherence, resulting in overestimates compared with naturalistic conditions. This pilot randomized trial may have been underpowered to detect some group differences.

CONCLUSIONS

A BMI offers promise as a disseminable adjunctive intervention for improving medication adherence for adolescents with BP. Future studies with larger samples can establish efficacy. NCT03203720.

The Otago Exercise Program With or Without Motivational Interviewing for Community-Dwelling Older Adults: A 12-Month Follow-Up of a Randomized, Controlled Trial

The aim of this randomized controlled trial was to examine the 12-month effects of the home-based Otago Exercise Program (OEP) with or without the support of motivational interviewing (MI) on community-dwelling people 75 years and older who needed walking aids and/or home help service. In total, 175 participants were randomized into three groups: OEP (n = 61), OEP with MI (n = 58), and a control group (n = 56) (M age = 83 years). Measures were physical performance, physical activity level, balance, grip strength, fall-related self-efficacy, fall rate, and fall injury rate. The OEP with and the OEP without MI, with the support of a physical therapist (six home visits and three phone calls), demonstrated no benefits in any of the measures compared with a control group. In this subgroup of pre-frail older adults, more frequent support by personnel may be required to secure efficient intensity and progression in the exercises performed on your own at home.

Fall Preventive Exercise With or Without Behavior Change Support for Community-Dwelling Older Adults: A Randomized Controlled Trial With Short-Term Follow-up

BACKGROUND AND PURPOSE

In Western countries, falls and fall-related injuries are a well-known threat to health in the aging population. Studies indicate that regular exercise improves strength and balance and can therefore decrease the incidence of falls and fall-related injuries. The challenge, however, is to provide exercise programs that are safe, effective, and attractive to the older population. The aim of this study was to investigate the short-term effect of a home-based exercise program with or without motivational interviewing (MI) compared with standard care on physical performance, fall self-efficacy, balance, activity level, handgrip strength, adherence to the exercise, and fall frequency.

METHOD

A total of 175 older adults participated in this randomized controlled study. They were randomly allocated for the Otago Exercise Program (OEP) (n = 61), OEP combined with MI (n = 58), or a control group (n = 56). The participants' mean age was 83 years. The recruitment period was from October 2012 to May 2015. Measurements of physical performance, fall self-efficacy, balance, activity level, handgrip strength, adherence to the exercise, and fall frequency were done before and 12 weeks after randomization.

RESULTS AND DISCUSSION

A total of 161 participants were followed up, and there were no significant differences between groups after a period of 12 weeks of regular exercise. Within the OEP + MI group, physical performance, fall self-efficacy, physical activity level, and handgrip strength improved significantly; likewise, improved physical performance and fall self-efficacy were found in the control group. A corresponding difference did not occur in the OEP group. Adherence to the exercise was generally high in both exercise groups.

CONCLUSION

In the short-term perspective, there were no benefits of an exercise program with or without MI regarding physical performance, fall self-efficacy, activity level, handgrip strength, adherence to the exercise, and fall frequency in comparison to a control group. However, some small effects occurred within the OEP + MI group, indicating that there may be some possible value in behavioral change support combined with exercise in older adults that requires further evaluation in both short- and long-term studies.

Computer-assisted motivational interviewing for contraceptive use in women leaving prison: A randomized controlled trial

OBJECTIVES

Rates of unintended pregnancies in women with a history of incarceration are high and access to contraception before and after arrest can be limited. Individualized counseling can better prepare women for healthy pregnancy or provide an opportunity for contraceptive education and access within correctional facilities. In this study, we assessed the efficacy of motivational interviewing as an individualized intervention to increase the initiation of contraceptive methods while incarcerated and continuation after release in female inmates who wanted to avoid pregnancy for at least one year after release.

STUDY DESIGN

We performed an RCT in a population of incarcerated women who wanted to avoid pregnancy. Women were randomized to either a computer-assisted motivational interviewing intervention group (n = 119) or an educational video with counseling control group. (n = 113). The primary outcome was initiation of a method of birth control prior to release from the correctional facility.

RESULTS

Initiation of contraception was higher in the intervention group (56% vs. 42%, p = 0.03), but this difference was not significant after controlling for number of male partners within the year prior to incarceration. There was no difference between the groups in the rates of pregnancies or STIs or continuation of contraception after release, which was generally low (21%).

CONCLUSION

Computer-assisted motivational interviewing did not improve uptake or continuation of contraception in this study.

IMPLICATIONS

Periods of incarceration provide an opportunity to offer contraceptive services to women who want to avoid a pregnancy. Motivational interviewing may not be an effective method to affect contraceptive behaviors in this population. Future research should explore the family planning values and preferences of women who become involved with the correctional system.

Motivational interviewing to promote health outcomes and behaviour change in multiple sclerosis: a systematic review

OBJECTIVE

To examine the evidence for motivational interviewing when used to assist individuals with multiple sclerosis manage their healthcare.

DATA SOURCES

The Cochrane, Embase, PsycINFO and PubMed databases were searched for studies published between 1983 and December 2019. The reference lists of included studies were additionally examined and Scopus citation searches conducted.

REVIEW METHODS

Study screening and data extraction were independently completed by two reviewers. Randomised controlled trials comparing motivational interviewing interventions for multiple sclerosis to usual care, wait-list or other active intervention controls were examined. Studies were assessed using the Cochrane Risk of Bias tool. Standardised mean differences (Hedges' g), 95% confidence intervals and P values were calculated for all health and behavioural outcomes.

RESULTS

Ten randomised controlled trials, involving a pooled sample of 987 adults with relapsing-remitting or progressive multiple sclerosis and mild to moderate impairment, were identified. Most trials had a low or unclear risk of methodological bias. Motivational interviewing, when used in conjunction with other counselling or rehabilitation techniques, resulted in significant immediate medium-to-very large improvements in multiple physical, psychological, social and behavioural outcomes (range: g = .34-2.68). Maintenance effects were promising (range: g = .41-1.11), although less frequently assessed (N_studies = 5) and of limited duration (1-7 months). Individual and group-based interventions, delivered in-person or by telephone, were all effective.

CONCLUSIONS

Motivational interviewing is a flexible counselling technique that may improve rehabilitation care for multiple sclerosis. However, evidence for persisting benefits to health outcomes and behaviour is currently limited.

The importance of shared language in rural behavioral health interventions: An exploratory linguistic analysis

A focus on the use of shared language to enhance congruence in interventionist-client dialogue is missing from traditional research on evidence-based practices and rural behavioral health. This study incorporates qualitative interactional sociolinguistics, which includes discourse analysis (typically written or audio recordings of face-to-face encounters with 11 clients and a study interventionist), to describe those speech patterns in a broad sense (dialect), as well as more specific use of communicative strategies to increase parity in the interaction between a rural interventionist delivering an evidence-based practice in the context of a research study with rural women opioid users in a non-therapeutic context. Study findings indicated that in the context of delivering the intervention, use of a shared language, language pattern congruence, and communication styles can greatly augment the intent of the approach with vulnerable populations. In addition, other communicative strategies connected with traditional Appalachian values - such as religion, home, and family - were also important. This study makes an important contribution to behavioral health research and practice by understanding critical factors that may influence evidence-based practice delivery, particularly in real-world settings with vulnerable populations. These findings have important implications for the utilization of creative approaches to understand critical components of the clinical interaction as indicators of fidelity.

Motivational interviewing for smoking cessation

BACKGROUND

Motivational Interviewing (MI) is a directive patient-centred style of counselling, designed to help people to explore and resolve ambivalence about behaviour change. It was developed as a treatment for alcohol abuse, but may help people to a make a successful attempt to stop smoking.

OBJECTIVES

To evaluate the efficacy of MI for smoking cessation compared with no treatment, in addition to another form of smoking cessation treatment, and compared with other types of smoking cessation treatment. We also investigated whether more intensive MI is more effective than less intensive MI for smoking cessation.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register for studies using the term motivat* NEAR2 (interview* OR enhanc* OR session* OR counsel* OR practi* OR behav*) in the title or abstract, or motivation* as a keyword. We also searched trial registries to identify unpublished studies. Date of the most recent search: August 2018.

SELECTION CRITERIA

Randomised controlled trials in which MI or its variants were offered to smokers to assist smoking cessation. We excluded trials that did not assess cessation as an outcome, with follow-up less than six months, and with additional non-MI intervention components not matched between arms. We excluded trials in pregnant women as these are covered elsewhere.

DATA COLLECTION AND ANALYSIS

We followed standard Cochrane methods. Smoking cessation was measured after at least six months, using the most rigorous definition available, on an intention-to-treat basis. We calculated risk ratios (RR) and 95% confidence intervals (CI) for smoking cessation for each study, where possible. We grouped eligible studies according to the type of comparison. We carried out meta-analyses where appropriate, using Mantel-Haenszel random-effects models. We extracted data on mental health outcomes and quality of life and summarised these narratively.

MAIN RESULTS

We identified 37 eligible studies involving over 15,000 participants who smoked tobacco. The majority of studies recruited participants with particular characteristics, often from groups of people who are less likely to seek support to stop smoking than the general population. Although a few studies recruited participants who intended to stop smoking soon or had no intentions to quit, most recruited a population without regard to their intention to quit. MI was conducted in one to 12 sessions, with the total duration of MI ranging from five to 315 minutes across studies. We judged four of the 37 studies to be at low risk of bias, and 11 to be at high risk, but restricting the analysis only to those studies at low or unclear risk did not significantly alter results, apart from in one case - our analysis comparing higher to lower intensity MI.We found low-certainty evidence, limited by risk of bias and imprecision, comparing the effect of MI to no treatment for smoking cessation (RR = 0.84, 95% CI 0.63 to 1.12; I2 = 0%; adjusted N = 684). One study was excluded from this analysis as the participants recruited (incarcerated men) were not comparable to the other participants included in the analysis, resulting in substantial statistical heterogeneity when all studies were pooled (I2 = 87%). Enhancing existing smoking cessation support with additional MI, compared with existing support alone, gave an RR of 1.07 (95% CI 0.85 to 1.36; adjusted N = 4167; I2 = 47%), and MI compared with other forms of smoking cessation support gave an RR of 1.24 (95% CI 0.91 to 1.69; I2 = 54%; N = 5192). We judged both of these estimates to be of low certainty due to heterogeneity and imprecision. Low-certainty evidence detected a benefit of higher intensity MI when compared with lower intensity MI (RR 1.23, 95% CI 1.11 to 1.37; adjusted N = 5620; I2 = 0%). The evidence was limited because three of the five studies in this comparison were at risk of bias. Excluding them gave an RR of 1.00 (95% CI 0.65 to 1.54; I2 = n/a; N = 482), changing the interpretation of the results.Mental health and quality of life outcomes were reported in only one study, providing little evidence on whether MI improves mental well-being.

AUTHORS' CONCLUSIONS

There is insufficient evidence to show whether or not MI helps people to stop smoking compared with no intervention, as an addition to other types of behavioural support for smoking cessation, or compared with other types of behavioural support for smoking cessation. It is also unclear whether more intensive MI is more effective than less intensive MI. All estimates of treatment effect were of low certainty because of concerns about bias in the trials, imprecision and inconsistency. Consequently, future trials are likely to change these conclusions. There is almost no evidence on whether MI for smoking cessation improves mental well-being.

Is fidelity to motivational interviewing associated with alcohol outcomes in treatment-seeking 60+ year-old citizens?

BACKGROUND

Part of the variability in treatment outcomes for Motivational Interviewing (MI) may be explained by differences in the fidelity to MI. The Motivational Interviewing Treatment Integrity manual version 4 (MITI 4) is an improved measure of fidelity to elements of MI. It is not known whether the fidelity to MI, as measured by the MITI 4, is related to treatment outcome.

OBJECTIVES

To examine whether fidelity to MI is associated with alcohol use outcomes - predictive validity of the MITI 4.

METHOD

Twenty percent of the recorded sessions at the Danish sites of the Elderly Study were randomly drawn and coded for fidelity to MI with the MITI 4. The Elderly Study was an international, randomized controlled trial, in which people 60 years or older with Alcohol Use Disorders received either four weeks of Motivational Enhancement Therapy (MET) or four weeks of MET combined with up to eight additional sessions of the Community Reinforcement Approach- Senior (MET+CRA-S). Elements of MI and summary scores of the MITI 4 were used as predictors in a mixed effects regression analysis. Treatment outcomes were use of alcohol and consequences of drinking at 26-weeks follow-up.

RESULTS

In total, 423 sessions representing 238 participants were randomly drawn and coded for fidelity to MI. Mean values of the treatment elements indicated high fidelity to MI, with higher fidelity to MI in the MET sessions, as compared to CRA-S sessions. None of the predictors in the multilevel model analyses were associated with outcome at follow-up. Exploratory analysis indicated reverse associations between one measure of MI-fidelity and drinking outcomes in the combined treatment (CRAS).

CONCLUSION

The fidelity of the MI intervention, received by participants in this study, did not predict better treatment outcomes. MI may be less effective in populations which are already committed to change behavior. As expected and validating for the MITI 4, fidelity to MI-elements was lower in the combination of MI with other treatment approaches. Additionally, the timing of MI in these combined settings might be important for effectiveness.

Implementation of motivational interviewing in a fall prevention exercise program: experiences from a randomized controlled trial

Objective

The elderly population over 65 is increasing globally, and interventions promoting health and preventive work, especially fall prevention, will constitute a large part of physiotherapists’ duties in the near future. To address the challenges of promoting effective and sustainable health behavior changes among older persons, physiotherapists need support when it comes to how to apply behavior change strategies, especially in fall prevention. Therefore, the aim of this study was to describe implementation of motivational interviewing in a fall prevention exercise program. This study is a side product of another project.

Results

Data from a recently performed three-armed randomized controlled trial were used to describe the implementation of motivational interviewing in the exercise group (n = 58). Level of motivation (priorities) and self-efficacy for both the physiotherapist and the participant in treatment, and to use a guide targeted towards the planned treatment are recommended actions. Regular meetings and follow ups as well as updates of motivational interviewing skills during a treatment period, should also be considered to achieve treatment fidelity.

Motivational interviewing in obese women with polycystic ovary syndrome - a pilot study

Lifestyle intervention is first line treatment in obese women with polycystic ovary syndrome (PCOS). The effect of motivational interviewing (MI) as add on to standard advice (SA) on weight loss and quality of life (QoL) has not been evaluated in obese women with PCOS. We aimed to examine whether MI as add on to SA induced higher weight loss and improved QoL in obese women with PCOS. Thirty-seven obese women with PCOS (BMI ≥30 kg/m2) were randomized to MI + SA (n = 19) vs. SA (n = 18) for six months. Anthropometric measures (BMI, waist) and questionnaires (World Health Organization-5 (WHO-5), Major Depression Index (MDI), Short Form-36 (SF-36) and PCOS-Questionnaire (PCOS-Q)) were performed at baseline and at follow-up, www.clinicaltrials.gov, NCT02924025. Twenty-eight (14 + 14) women completed the study. At baseline, 24/28 women had WHO-5 scores <67 and 12/28 women had MDI scores indicating depression. Changes in weight and QoL were similar between MI + SA vs. SA group. However, WHO-5 (p=.028) and MDI (p=.008) scores improved significantly in the 12/24 women with MDI scores indicating depression. MI as add on to SA did not improve QoL or weight loss. Obese women with PCOS had low QoL.

Effectiveness of Motivational Interviewing on adult behaviour change in health and social care settings: A systematic review of reviews

BACKGROUND

The challenge of addressing unhealthy lifestyle choice is of global concern. Motivational Interviewing has been widely implemented to help people change their behaviour, but it is unclear for whom it is most beneficial. This overview aims to appraise and synthesise the review evidence for the effectiveness of Motivational Interviewing on health behaviour of adults in health and social care settings.

METHODS

A systematic review of reviews. Methods were pre-specified and documented in a protocol (PROSPERO-CRD42016049278). We systematically searched 7 electronic databases: CDSR; DARE; PROSPERO; MEDLINE; CINAHL; AMED and PsycINFO from 2000 to May 2018. Two reviewers applied pre-defined selection criteria, extracted data using TIDIER guidelines and assessed methodological quality using the ROBIS tool. We used GRADE criteria to rate the strength of the evidence for reviews including meta-analyses.

FINDINGS

Searches identified 5222 records. One hundred and four reviews, including 39 meta-analyses met the inclusion criteria. Most meta-analysis evidence was graded as low or very low (128/155). Moderate quality evidence for mainly short term (<6 months) statistically significant small beneficial effects of Motivational Interviewing were found in 11 of 155 (7%) of meta-analysis comparisons. These outcomes include reducing binge drinking, frequency and quantity of alcohol consumption, substance abuse in people with dependency or addiction, and increasing physical activity participation.

CONCLUSIONS

We have created a comprehensive map of reviews relating to Motivational Interviewing to signpost stakeholders to the best available evidence. More high quality research is needed to be confident about the effectiveness of Motivational Interviewing. We identified a large volume of low quality evidence and many areas of overlapping research. To avoid research waste, it is vital for researchers to be aware of existing research, and the implications arising from that research. In the case of Motivational Interviewing issues relating to monitoring and reporting fidelity of interventions need to be addressed.

Vida PURA: An assessment of the fidelity of promotor-delivered screening and brief intervention to reduce unhealthy alcohol use among Latino day laborers

We assessed the fidelity of promotores conducting screening and brief intervention (SBI) to reduce unhealthy alcohol use among Latino immigrant day laborers in the Vida PURA study. We reviewed 32 audio-recorded brief interventions to assess promotor adherence to the intervention protocol and to evaluate their motivational interviewing (MI) technique with the Motivational Interviewing Treatment Integrity (MITI) 4.2.1 tool. Promotores delivered three core intervention steps in 78% of recordings and achieved basic MI competence across all domains and proficiency in 50% of measures. Our results suggest that promotores can be trained to deliver SBI in community settings with fidelity.

Effectiveness of the blended-care lifestyle intervention 'PerfectFit': a cluster randomised trial in employees at risk for cardiovascular diseases

BACKGROUND

Web-based lifestyle interventions at the workplace have the potential to promote health and work productivity. However, the sustainability of effects is often small, which could be enhanced by adding face-to-face contacts, so-called 'blended care'. Therefore, this study evaluates the effects of a blended workplace health promotion intervention on health and work outcomes among employees with increased cardiovascular risk.

METHODS

In this multicentre cluster-randomised controlled trial (PerfectFit), 491 workers in 18 work units from military, police, and a hospital with increased cardiovascular risk were randomised into two intervention groups. The limited intervention (n = 213; 9 clusters) consisted of a web-based Health Risk Assessment with advice. In the extensive intervention (n = 271; 8 clusters), coaching sessions by occupational health physicians using motivational interviewing were added. One cluster dropped out after randomisation but before any inclusion of subjects. Primary outcome was self-rated health. Secondary outcomes were body weight, body mass index (BMI), work productivity, and health behaviours. Follow-up measurements were collected at 6 and 12 months. Effect sizes were determined in mixed effects models.

RESULTS

At 12 months, the extensive intervention was not statistically different from the limited intervention for self-rated health (4.3%; 95%CI -5.3-12.8), BMI (- 0.81; 95%CI -1.87-0.26) and body weight (- 2.16; 95%CI -5.49-1.17). The within-group analysis showed that in the extensive intervention group body weight (- 3.1 kg; 95% CI -2.0 to - 4.3) was statistically significantly reduced, whereas body weight remained stable in the limited intervention group (+ 0.2 kg; 95% CI -1.4 to 1.8). In both randomised groups productivity loss and physical activity increased and excessive alcohol use decreased significantly at 12 months.

CONCLUSIONS

There were no effects on self-rated health, body weight, and BMI. However, within the group with web-based tailored Health Risk Assessment including personalized advice body weight reduced significantly. Adding motivational coaching is promising to reduce body weight.

One-Year Adherence to the Otago Exercise Program With or Without Motivational Interviewing in Community-Dwelling Older Adults

This study investigated if behavioral factors, treatment with behavioral support, readiness to change, fall self-efficacy, and activity habits could predict long-term adherence to an exercise program. Included in this study were 114 community-dwelling older adults who had participated in one of two home-based exercise interventions. Behavioral factors associated with adherence to the exercise program over 52 weeks were analyzed. The behavioral factors, specifically activity habits at baseline, significantly predicted adherence to the exercise program, with an odds ratio = 3.39, 95% confidence interval [1.38, 8.32], for exercise and an odds ratio = 6.11, 95% confidence interval [2.34, 15.94], for walks. Being allocated to a specific treatment including motivational interviewing was also significantly predictive: odds ratio = 2.47, 95% confidence interval [1.11, 5.49] for exercise adherence. In conclusion, activity habits and exercise in combination with motivational interviewing had a significant association with adherence to the exercise program at a 1-year follow-up.

Rating motivational interviewing fidelity from thin slices

Monitoring fidelity to psychosocial treatments is critical to dissemination, process and outcome research, and internal validity in efficacy trials. However, the costs required to behavior code fidelity to treatments like motivational interviewing (MI) over many therapists and sessions quickly become intractable. Coding less of a session accelerates the process, but it is not clear how much of a session must be evaluated to capture the fidelity of the entire session. The present study used a "thin slice" (Ambady & Rosenthal, 1992) paradigm to explore the degree to which variously sized thin slices of MI fidelity related to fidelity ratings for a full session. We randomly selected contiguous and noncontiguous segments of MI sessions at each whole percent of sessions (i.e., a slice consisting of 1% of session utterances, another at 2%, etc.). We then computed MI fidelity scores from these segments and calculated agreement with fidelity ratings obtained from the full session. We compared thin slice agreement with full sessions against interrater agreement and found that approximately a third of a session (9 min, 26 seconds in our sample) had sufficient agreement to approach interrater levels. These results provide a reference for researchers and clinicians to make efficient and informed use of their behavior coding resources. In addition, our results add to the behavior slicing literature, indicating that small therapist behavior samples adequately describe overall session behavior. (PsycINFO Database Record

Evaluating the efficacy of an integrated motivational interviewing and multi-modal exercise intervention for youth with major depression: Healthy Body, Healthy Mind randomised controlled trial protocol

BACKGROUND

Recent meta-analytic reviews suggest exercise can reduce depression severity among adults with major depressive disorder (MDD); however, efficacy studies with depressed youth are limited. Few studies have investigated the efficacy of multi-modal exercise interventions in this population, addressed treatment engagement, or explored the differential effects of exercise on depressive symptom profiles.

OBJECTIVES

This paper describes the study protocol and recruitment pattern for an assessor blinded, two-arm randomised controlled trial investigating the efficacy of an integrated motivational interviewing (MI) and multi-modal exercise intervention in youth diagnosed with MDD. Associations between depressive symptom profiles (cognitive, somatic and affective) and psychological, physiological (fitness), and biological (blood biomarker) outcomes will also be examined.

METHODS

Participants aged 15-25 years with current MDD were recruited. Eligible participants were randomised and stratified according to gender and depression severity to either an immediate or delayed (control) group. The immediate group received a brief MI intervention followed by a 12-week small group exercise intervention (3 times per week for 1 h), all delivered by personal trainers. The delayed control group received the same intervention 12-weeks later. Both groups were reassessed at mid-treatment or mid-control, post-treatment or post-control, and follow-up (12 weeks post-treatment).

RESULTS

68 participants were recruited and randomly allocated to an intervention group.

CONCLUSION

This trial will increase our understanding of the efficacy of multi-modal exercise interventions for depression and the specific effects of exercise on depressive symptom profiles. It also offers a novel contribution by addressing treatment engagement in exercise efficacy trials in youth with MDD.

Treatment Fidelity of a Nurse-Led Motivational Interviewing-Based Pre-Treatment in Pain Rehabilitation

Treatment fidelity and proficiency of a nurse-led motivational interviewing (MI)-based pre-treatment and control condition was evaluated. A random sample was scored by means of the Motivational Interviewing Treatment Integrity (MITI) scale, and a second rater was in charge. MI fidelity was satisfactory for three out of five ratings. Most mean ratings were higher in the MI-based intervention, but differences were not statistically significant. The threshold for beginning MI proficiency was only exceeded for one score and one additional measure. In general, higher levels of fidelity in the intervention condition confirmed that MI was partially applied there. Although the quality of MI delivery as well as mixed inter-rater reliabilities of the fidelity scores leaves room for improvement, robust findings between the two raters were found. These results suggest the need for rigor selection of MI counselors on beforehand, and continuous supervision. Furthermore, fidelity check in studies using MI is needed.
