A telephone-only motivational intervention to increase physical activity in rural adults: a randomized controlled trial

Effectiveness of behavioural interventions with motivational interviewing on physical activity outcomes in adults: systematic review and meta-analysis

OBJECTIVE

To evaluate the effectiveness of behavioural interventions that include motivational interviewing on physical activity outcomes in adults.

DESIGN

Systematic review and meta-analysis.

STUDY SELECTION

A search of seven databases for randomised controlled trials published from inception to 1 March 2023 comparing a behavioural intervention including motivational interviewing with a comparator without motivational interviewing on physical activity outcomes in adults. Outcomes of interest were differences in change in quantitative measures of total physical activity, moderate to vigorous physical activity (MVPA), and sedentary time.

DATA EXTRACTION AND SYNTHESIS

Two reviewers extracted data and assessed risk of bias. Population characteristics, intervention components, comparison groups, and outcomes of studies were summarised. For overall main effects, random effects meta-analyses were used to report standardised mean differences (SMDs) and 95% confidence intervals (CIs). Differential effects based on duration of follow-up, comparator type, intervention duration, and disease or health condition of participants were also examined.

RESULTS

129 papers reporting 97 randomised controlled trials totalling 27 811 participants and 105 comparisons were included. Interventions including motivational interviewing were superior to comparators for increases in total physical activity (SMD 0.45, 95% CI 0.33 to 0.65, equivalent to 1323 extra steps/day; low certainty evidence) and MVPA (0.45, 0.19 to 0.71, equivalent to 95 extra min/week; very low certainty evidence) and for reductions in sedentary time (-0.58, -1.03 to -0.14, equivalent to -51 min/day; very low certainty evidence). Evidence for a difference in any outcome compared with comparators of similar intensity was lacking. The magnitude of effect diminished over time, and evidence of an effect of motivational interviewing beyond one year was lacking. Most interventions involved patients with a specific health condition, and evidence of an effect of motivational interviewing to increase MVPA or decrease sedentary time was lacking in general population samples.

CONCLUSIONS

Certainty of the evidence using motivational interviewing as part of complex behavioural interventions for promoting total physical activity in adults was low, and for MVPA and sedentary time was very low. The totality of evidence suggests that although interventions with motivational interviewing increase physical activity and decrease sedentary behaviour, no difference was found in studies where the effect of motivational interviewing could be isolated. Effectiveness waned over time, with no evidence of a benefit of motivational interviewing to increase physical activity beyond one year.

Global rural health disparities in Alzheimer's disease and related dementias: State of the science

INTRODUCTION

Individuals living in rural communities are at heightened risk for Alzheimer's disease and related dementias (ADRD), which parallels other persistent place-based health disparities. Identifying multiple potentially modifiable risk factors specific to rural areas that contribute to ADRD is an essential first step in understanding the complex interplay between various barriers and facilitators.

METHODS

An interdisciplinary, international group of ADRD researchers convened to address the overarching question of: "What can be done to begin minimizing the rural health disparities that contribute uniquely to ADRD?" In this state of the science appraisal, we explore what is known about the biological, behavioral, sociocultural, and environmental influences on ADRD disparities in rural settings.

RESULTS

A range of individual, interpersonal, and community factors were identified, including strengths of rural residents in facilitating healthy aging lifestyle interventions.

DISCUSSION

A location dynamics model and ADRD-focused future directions are offered for guiding rural practitioners, researchers, and policymakers in mitigating rural disparities.

HIGHLIGHTS

Rural residents face heightened Alzheimer's disease and related dementia (ADRD) risks and burdens due to health disparities. Defining the unique rural barriers and facilitators to cognitive health yields insight. The strengths and resilience of rural residents can mitigate ADRD-related challenges. A novel "location dynamics" model guides assessment of rural-specific ADRD issues.

Long-term Effectiveness of mHealth Physical Activity Interventions: Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

Mobile health (mHealth) interventions can increase physical activity (PA); however, their long-term impact is not well understood.

OBJECTIVE

The primary aim of this study is to understand the immediate and long-term effects of mHealth interventions on PA. The secondary aim is to explore potential effect moderators.

METHODS

We performed this study according to the Cochrane and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched PubMed, the Cochrane Library, SCOPUS, and PsycINFO in July 2020. Eligible studies included randomized controlled trials of mHealth interventions targeting PA as a primary outcome in adults. Eligible outcome measures were walking, moderate-to-vigorous physical activity (MVPA), total physical activity (TPA), and energy expenditure. Where reported, we extracted data for 3 time points (ie, end of intervention, follow-up ≤6 months, and follow-up >6 months). To explore effect moderators, we performed subgroup analyses by population, intervention design, and control group type. Results were summarized using random effects meta-analysis. Risk of bias was assessed using the Cochrane Collaboration tool.

RESULTS

Of the 2828 identified studies, 117 were included. These studies reported on 21,118 participants with a mean age of 52.03 (SD 14.14) years, of whom 58.99% (n=12,459) were female. mHealth interventions significantly increased PA across all the 4 outcome measures at the end of intervention (walking standardized mean difference [SMD] 0.46, 95% CI 0.36-0.55; P<.001; MVPA SMD 0.28, 95% CI 0.21-0.35; P<.001; TPA SMD 0.34, 95% CI 0.20-0.47; P<.001; energy expenditure SMD 0.44, 95% CI 0.13-0.75; P=.01). Only 33 studies reported short-term follow-up measurements, and 8 studies reported long-term follow-up measurements in addition to end-of-intervention results. In the short term, effects were sustained for walking (SMD 0.26, 95% CI 0.09-0.42; P=.002), MVPA (SMD 0.20, 95% CI 0.05-0.35; P=.008), and TPA (SMD 0.53, 95% CI 0.13-0.93; P=.009). In the long term, effects were also sustained for walking (SMD 0.25, 95% CI 0.10-0.39; P=.001) and MVPA (SMD 0.19, 95% CI 0.11-0.27; P<.001). We found the study population to be an effect moderator, with higher effect scores in sick and at-risk populations. PA was increased both in scalable and nonscalable mHealth intervention designs and regardless of the control group type. The risk of bias was rated high in 80.3% (94/117) of the studies. Heterogeneity was significant, resulting in low to very low quality of evidence.

CONCLUSIONS

mHealth interventions can foster small to moderate increases in PA. The effects are maintained long term; however, the effect size decreases over time. The results encourage using mHealth interventions in at-risk and sick populations and support the use of scalable mHealth intervention designs to affordably reach large populations. However, given the low evidence quality, further methodologically rigorous studies are warranted to evaluate the long-term effects.

The effect of the electronic platform of menopausal health screen system and counseling intervention on the empowerment of menopausal women: a quasi-experimental study

This article explores the efficacy of the electronic platform of menopausal health screen system (EPMHSS) and counseling intervention on the empowerment of menopausal women, seventy four participants were randomly assigned to this study. The intervention group significantly relieved menopausal disturbance, reduced uncertainty, increased health behaviors, and decreased waist circumference after the fourth and eighth week compared with the control group. Our results proved that EPMHSS and counseling would help menopausal women to become more aware of their health, as a result, effectively empowered themselves to take actions for improving their health.

Exploring the feasibility and impact of positive psychology-motivational interviewing interventions to promote positive affect and physical activity in type 2 diabetes: design and methods from the BEHOLD-8 and BEHOLD-16 clinical trials

BACKGROUND

Physical activity among those with type 2 diabetes (T2D) is independently associated with superior medical outcomes, but existing behavioral interventions have not led to widespread increases in activity in this population. A remotely delivered intervention that targets well-being constructs associated with greater activity and assists in the creation of specific physical activity goals has the potential to improve activity and outcomes in T2D.

OBJECTIVE

To outline the rationale and methods of two studies designed to assess the impact and optimal duration of a combined positive psychology-motivational interviewing (PP-MI) intervention for inactive persons with T2D.

METHODS

We conducted trials studying 8-week (BEHOLD-8;) and 16-week (BEHOLD-16;) phone-delivered interventions, compared to attention-matched control conditions. In a two-step randomization design, participants were allocated randomly first to study (BEHOLD-8 or BEHOLD-16), then to study condition within study. The primary aims in both trials were feasibility (rates of session completion) and acceptability (participant session ratings), with additional aims examining intervention effects on accelerometer-measured physical activity, psychological measures, and health-related metrics (e.g. vital signs). Main analyses, currently being conducted, will utilize mixed effects models between study conditions, and secondary analyses will utilize the same models to compare the 8- and 16-week PP-MI interventions on feasibility and impact.

RESULTS

Enrollment and data collection have been completed for both trials (BEHOLD-8: N = 60; BEHOLD-16: N = 70), and data analysis is ongoing to assess feasibility and acceptability within study, as well as the relative feasibility and acceptability of the PP-MI interventions across the two studies. We will also explore impact on clinical outcomes between groups.

CONCLUSIONS

This design will address how intervention content (i.e. PP elements vs. no PP elements) and intervention duration (8 weeks vs. 16 weeks) affect feasibility, acceptability, and impact, allowing intervention optimization before a next-step larger clinical trial.

Strengthened General Self-Efficacy with Multidisciplinary Vocational Rehabilitation in Women on Long-Term Sick Leave: A Randomised Controlled Trial

Purpose To investigate the effects of two vocational rehabilitation interventions on self-efficacy, for women on long-term sick leave ≥ 1 year due to chronic pain and/or mental illness. Methods This study uses data from a randomised controlled trial consisting of two phases and comprising 401 women on long-term sick leave. They were allocated to either (1) a multidisciplinary team assessment and multimodal intervention (TEAM), (2) acceptance and commitment therapy (ACT), or (3) control group. Data were collected through repeated measurements from self-reported questionnaires before intervention, 6 and 12 months later and registry data. Data from measurements of general self-efficacy, sociodemographics, anxiety and depression were analysed with linear regression analyses. Results During the intervention period, the women in the TEAM group's self-efficacy mean increased from 2.29 to 2.74. The adjusted linear regression model, which included group allocation, sociodemographics, self-efficacy pre-treatment, anxiety and depression showed increased self-efficacy for those in the TEAM intervention at 12 months (B = 0.25, 95% CI 0.10-0.41). ACT intervention had no effect on self-efficacy at 12 months (B = 0.02, 95% CI - 0.16 to 0.19). The results in the adjusted model also showed that higher self-efficacy at pre-treatment was associated with a higher level of self-efficacy at 12 months (B = 0.68, 95% CI 0.54-0.81). Conclusion A multidisciplinary team assessment and multimodal intervention increased self-efficacy in women on sick leave for an extremely long time (mean 7.8 years) who had a low mean level of self-efficacy prior to inclusion. Thus, self-efficacy needs to be addressed in vocational rehabilitation.

Positive experiences of a vocational rehabilitation intervention for individuals on long-term sick leave, the Dirigo project: a qualitative study

BACKGROUND

The process of returning to work after long-term sick leave can sometimes be complex. Many factors, (e.g. cooperation between different authorities and the individual as well as individual factors such as health, emotional well-being and self-efficacy) may have an impact on an individual's ability to work. The aim of this study was to investigate clients' experiences with an individually tailored vocational rehabilitation, the Dirigo project, and encounters with professionals working on it. The Dirigo project was based on collaboration between rehabilitation authorities, individually tailored interventions and a motivational interviewing approach.

METHODS

A descriptive qualitative design was used with data collected through interviews. Fourteen individuals on long-term sick leave took part in individual semi-structured interviews. The interviews were analysed using content analysis.

RESULTS

The analysis showed overall positive experience of methods and encounters with professionals in a vocational rehabilitation project. The positive experiences were based on four key factors: 1. Opportunities for receiving various dimensions of support. 2. Good overall treatment by the professionals. 3. Satisfaction with the working methods of the project, and 4. Opportunities for personal development.

CONCLUSIONS

The main result showed that the clients had an overall positive experience of a vocational rehabilitation project and encounters with professionals who used motivational interviewing as a communication method. The overall positive experience indicated that their interactions with the different professionals may have affected their self-efficacy in general and in relation to transition to work. The knowledge is essential for the professionals working in the area of vocational rehabilitation. However, vocational rehabilitation interventions also need a societal approach to be able to offer clients opportunities for job training and real jobs.

Beyond face-to-face individual counseling: A systematic review on alternative modes of motivational interviewing in substance abuse treatment and prevention

OBJECTIVES

This systematic review aimed to synthesize the evidence on the effectiveness of motivational interviewing (MI), delivered in modes other than face-to-face individual counseling, in preventing and treating substance abuse related behaviors.

METHODS

Four databases (PubMed/MEDLINE, PsycINFO, ISI Web of Science and Cochrane Library) were searched for randomised clinical trials (RCTs) that evaluated the effectiveness of alternative modes of MI (other than face-to-face individual counseling) in preventing and treating substance abuse. Eligible studies were rated on methodological quality and their findings were qualitatively synthesized.

RESULTS

A total of 25 articles (on 22 RCTs) were eligible for this review. Beyond face-to-face counseling, telephone was the most frequently used medium for delivering MI (11 studies), followed by Internet communication (4 studies) and short message service (SMS) (2 studies). Mail was incorporated as a supplement in one of the studies for telephone MI. In contrast to one-to-one individual counseling, group MI was adopted in 5 studies. The effectiveness of telephone MI in treating substance abuse was supported by all of the published RCTs we located. Internet-based MI was effective in preventing and treating alcoholism, but its outcome appeared to be inconsistent for smoking cessation and poor for abstinence from illicit drugs. SMS-based MI appeared to be useful for controlling tobacco and drinking. Group MI was attempted for quitting alcohol and drugs, with mixed findings on its outcomes.

CONCLUSIONS

Collectively, the studies reviewed indicate that telephone MI is a promising mode of intervention in treating and preventing substance abuse. The effectiveness of other alternative modes (SMS-based MI, Internet-based MI and group MI) remains inconclusive given the controversial findings and a limited number of studies. By synthesizing the currently available evidence, this systematic review suggested that telephone MI might be considered as an alternative to face-to-face MI for treating and preventing substance abuse. Further research is needed to investigate the effectiveness of SMS-based MI, Internet MI, group MI and other alternative modes. Studies with methodological rigor and incorporating MI fidelity measures have great potential to advance the understanding in this field.

[Development and Evaluation of a Motivational Interviewing Program for Exercise Improvement in Persons with Physical Disabilities]

PURPOSE

The aims of this study were to develop a motivational interviewing program for exercise improvement in persons with physical disabilities and to examine the effect of this motivational interviewing intervention.

METHODS

The study employed a nonequivalent control group pretest and posttest design. A total of 62 persons with physical disabilities (30 in the experimental group, 32 in the control group) were recruited from 2 community rehabilitation centers. The experimental group received 8 sessions of a group motivational interviewing program, scheduled once a week, with each session lasting 60 minutes. Test measures were completed before the intervention, immediately after the end of the intervention, 2 weeks later, and 6 weeks after the end of the intervention. Measures included self-efficacy for exercise, decisional balance for exercise, stage of change for exercise, regularity of exercise, exercise maintenance, and independent living ability. Data were analyzed using the χ²-test, Fisher's exact test, Independent samples t-test, and repeated measures ANOVA, conducted using IBM SPSS Statistics version 18.

RESULTS

The experimental group showed a significant increase in self-efficacy for exercise (F=50.98, p<.001), benefit (pros) of exercise (F=24.16, p<.001), and independent living ability (F=50.94, p<.001), and a significant decrease in loss (cons) of exercise (F=26.50, p<.001). There were significant differences between the two groups in stages of change for exercise (p<.001), regularity of exercise (p<.001), and exercise maintenance (χ²=26.61, p<.001).

CONCLUSION

The motivational interviewing program has the potential to improve exercise levels in persons with physical disabilities.

A feasibility randomised controlled trial of a motivational interviewing-based intervention for weight loss maintenance in adults

BACKGROUND

Obesity has significant health and NHS cost implications. Relatively small reductions in weight have clinically important benefits, but long-term weight loss maintenance (WLM) is challenging. Behaviour change interventions have been identified as key for WLM. Motivation is crucial to supporting behaviour change, and motivational interviewing (MI) has been identified as a successful approach to changing health behaviours. The study was designed as an adequately powered, pragmatic randomised controlled trial (RCT); however, owing to recruitment issues, the study became a feasibility trial.

OBJECTIVES

To assess recruitment, retention, feasibility, acceptability, compliance and delivery of a 12-month intervention to support WLM. Secondary objectives were to assess the impact of the intervention on body mass index (BMI) and other secondary outcomes.

DESIGN

Three-arm individually randomised controlled trial comprising an intensive arm, a less intensive arm and a control arm.

SETTING

Community setting in South Wales and the East Midlands.

PARTICIPANTS

Individuals aged 18-70 years with a current or previous BMI of ≥ 30 kg/m(2) who could provide evidence of at least 5% weight loss during the previous 12 months.

INTERVENTION

Participants received individually tailored MI, which included planning and self-monitoring. The intensive arm received six face-to-face sessions followed by nine telephone sessions. The less intensive arm received two face-to-face sessions followed by two telephone sessions. The control arm received a leaflet advising them on healthy lifestyle.

MAIN OUTCOME MEASURES

Feasibility outcomes included numbers recruited, retention and adherence. The primary effectiveness outcome was BMI at 12 months post randomisation. Secondary outcomes included waist circumference, waist-to-hip ratio, physical activity, proportion maintaining weight loss, diet, quality of life, health service resource usage, binge eating and well-being. A process evaluation assessed intervention delivery, adherence, and participants' and practitioners' views. Economic analysis aimed to assess cost-effectiveness in terms of quality-adjusted life-years (QALYs).

RESULTS

A total of 170 participants were randomised. Retention was good (84%) and adherence was excellent (intensive, 83%; less intensive, 91%). The between-group difference in mean BMI indicated the intensive arm had BMIs 1.0 kg/m(2) lower than the controls [95% confidence interval (CI) -2.2 kg/m(2) to 0.2 kg/m(2)]. Similarly, a potential difference was found in weight (average difference of 2.8 kg, 95% CI -6.1 kg to 0.5 kg). The intensive arm had odds of maintaining on average 43% [odds ratio(OR) 1.4, 95% CI 0.6 to 3.5] higher than controls. None of these findings were statistically significant. Further analyses controlling for level of adherence indicated that average BMI was 1.2 kg/m(2) lower in the intensive arm than the control arm (95% CI -2.5 kg/m(2) to 0.0 kg/m(2)). The intensive intervention led to a statistically significant difference in weight (mean -3.7 kg, 95% CI -7.1 kg to -0.3 kg). The other secondary outcomes showed limited evidence of differences between groups. The intervention was delivered as planned, and both practitioners and participants were positive about the intervention and its impact. Although not powered to assess cost-effectiveness, results of this feasibility study suggest that neither intervention as currently delivered is likely to be cost-effective in routine practice.

CONCLUSION

This is the first trial of an intervention for WLM in the UK, the intervention is feasible and acceptable, and retention and adherence were high. The main effectiveness outcome showed a promising mean difference in the intensive arm. Owing to the small sample size, we are limited in the conclusions we can draw. However, findings suggest that the intensive intervention may facilitate long-term weight maintenance and, therefore, further testing in an effectiveness trial may be indicated. Research examining WLM is in its infancy, further research is needed to develop our understanding of WLM and to expand theory to inform the development of interventions to be tested in rigorously designed RCTs with cost-effectiveness assessed.

Resistance Exercise Reduces Body Fat and Insulin During Androgen-Deprivation Therapy for Prostate Cancer

PURPOSE/OBJECTIVES

To determine whether exercise could reduce biomarkers of cancer progression in prostate cancer survivors (PCSs) on androgen-deprivation therapy (ADT).

DESIGN

Randomized, controlled trial.

SETTING

Oregon Health and Science University School of Nursing.

SAMPLE

51 PCSs randomized to one year of resistance and impact training or a stretching control group.

METHODS

The authors investigated changes in body composition and cancer-related biomarkers, and the influence of age and fat loss on changes in biomarkers.

MAIN RESEARCH VARIABLES

Body composition (total fat, trunk fat, and lean mass), insulin, insulin-like growth factor-1, and sex hormone-binding globulin.

FINDINGS

In the 36 PCSs with baseline and 12-month data, total fat (p = 0.02) and trunk fat (p = 0.06) mass decreased in the training group compared to gains in controls. Loss of total and trunk fat each mediated the relationship between groups and one-year change in insulin (p < 0.05). Age moderated the insulin response to exercise where insulin reductions were smaller with increasing age (p = 0.03).

CONCLUSIONS

Resistance and impact exercise may reduce body fat among PCSs undergoing ADT, in turn exerting an insulin-lowering effect.

IMPLICATIONS FOR NURSING

Nurses should counsel PCSs to exercise to reduce the risk of obesity and associated conditions, including cancer progression.

Phone-based motivational interviewing to increase self-efficacy in individuals with phenylketonuria

OBJECTIVE

To measure change in patient activation and self-efficacy in individuals with phenylketonuria (PKU) before and after a 6-month phone-based motivational interviewing (MI) intervention and determine the feasibility of implementing dietary counseling for PKU using an MI approach.

METHODS

Participants (n = 31) included preadolescents (7-12 years), adolescents (13-17 years), and adults (18-35 years) with early-treated PKU. Participants completed online questionnaires assessing self-reported stage of change (SOC), patient activation, and self-efficacy for PKU self-management behaviors. The intervention included monthly phone-based dietary counseling using MI during which participants set monthly goals.

RESULTS

Patient activation and self-efficacy were significantly different by age group (both p < 0.01) with higher scores in older participants. Self-efficacy significantly increased from baseline to month 6 among adolescents and adults (7.4 ± 1.9 and 8.6 ± 1.3, respectively, p = 0.002). Preadolescents did not have a significant change in self-efficacy (p = 0.79). There was no increase in patient activation for preadolescents or adolescents/adults (p = 0.19 and p = 0.24, respectively). Indicators of learning problems were not significantly associated with self-efficacy (p = 0.33) or patient activation (p = 0.83).

CONCLUSION

These results demonstrate the feasibility of implementing phone-based dietary counseling for PKU using MI. This study also supports further investigation of MI as an intervention approach to improving self-efficacy and self-management behaviors in adolescents and adults with PKU.

The Effect of Motivational Interviewing on Prescription Opioid Adherence Among Older Adults With Chronic Pain

PURPOSE

To test the effect of office-based motivational interviewing (MI) on prescription opioid adherence in older adults with chronic pain.

DESIGN AND METHODS

Pre- and post-design was used. Thirty chronic pain patients participated in a 4-week MI in two outpatient settings.

FINDINGS

Participants demonstrated a significantly reduced risk of prescription opioid misuse, decreased substance use, increased self-efficacy, increased motivation to change, and decreased depression at both the post-test and 1-month follow-up.

PRACTICE IMPLICATION

MI can be effectively delivered in outpatient settings for older adults who are at risk for opioid misuse. Clinicians could incorporate MI techniques to enhance prescription opioid adherence.

Motivational Interviewing Support for a Behavioral Health Internet Intervention for Drivers with Type 1 Diabetes

While Internet interventions can improve health behaviors, their impact is limited by program adherence. Supporting program adherence through telephone counseling may be useful, but there have been few direct tests of the impact of support. We describe a Telephone Motivational Interviewing (MI) intervention targeting adherence to an Internet intervention for drivers with Type 1 Diabetes, DD.com, and compare completion of intervention benchmarks by those randomized to DD.com plus MI vs. DD.com only. The goal of the pre-intervention MI session was to increase the participant's motivation to complete the Internet intervention and all its assignments, while the goal of the post-treatment MI session was to plan for maintaining changes made during the intervention. Sessions were semi-structured and partially scripted to maximize consistency. MI Fidelity was coded using a standard coding system, the MITI. We examined the effects of MI support vs. no support on number of days from enrollment to program benchmarks. Results show that MI sessions were provided with good fidelity. Users who received MI support completed some program benchmarks such as Core 4 (t_{176 df}= -2.25; p<.03) and 11 of 12 monthly driving diaries significantly sooner, but support did not significantly affect time to intervention completion (t_{177 df}= -1.69; p<. 10) or rates of completion. These data suggest that there is little benefit to therapist guidance for Internet interventions including automated email prompts and other automated minimal supports, but that a booster MI session may enhance collection of follow-up data.

Effect of physical activity, social support, and skills training on late-life emotional health: a systematic literature review and implications for public health research

PURPOSE

Given that emotional health is a critical component of healthy aging, we undertook a systematic literature review to assess whether current interventions can positively affect older adults' emotional health.

METHODS

A national panel of health services and mental health researchers guided the review. Eligibility criteria included community-dwelling older adult (aged ≥ 50 years) samples, reproducible interventions, and emotional health outcomes, which included multiple domains and both positive (well-being) and illness-related (anxiety) dimensions. This review focused on three types of interventions - physical activity, social support, and skills training - given their public health significance and large number of studies identified. Panel members evaluated the strength of evidence (quality and effectiveness).

RESULTS

In all, 292 articles met inclusion criteria. These included 83 exercise/physical activity, 25 social support, and 40 skills training interventions. For evidence rating, these 148 interventions were categorized into 64 pairings by intervention type and emotional health outcome, e.g., strength training targeting loneliness or social support to address mood. 83% of these pairings were rated at least fair quality. Expert panelists found sufficient evidence of effectiveness only for skills training interventions with health outcomes of decreasing anxiety and improving quality of life and self-efficacy. Due to limitations in reviewed studies, many intervention-outcome pairings yielded insufficient evidence.

CONCLUSION

Skills training interventions improved several aspects of emotional health in community-dwelling older adults, while the effects for other outcomes and interventions lacked clear evidence. We discuss the implications and challenges in moving forward in this important area.

Mechanisms of change within motivational interviewing in relation to health behaviors outcomes: a systematic review

OBJECTIVE

Motivational interviewing (MI) has been identified as an effective treatment for health behaviors. Understanding the mechanisms of MI could have practical implications for MI delivery. This review is the first to examine mechanisms within MI that affect health behavior outcomes and summarizes and evaluates the evidence.

METHODS

A systematic literature search was conducted in PSYCHINFO, MEDLINE and EMBASE to identify studies that delivered individual MI in the context of health behaviors, excluding addictions, and investigated mechanisms of MI. Effect sizes were calculated.

RESULTS

291 studies were identified and 37 met the inclusion criteria. Few of the 37 studies included, conducted mediation analyses. MI spirit and motivation were the most promising mechanisms of MI. Although self-efficacy was the most researched, it was not identified as a mechanism of MI. Study quality was generally poor.

CONCLUSION

Although this review has indicated possible mechanisms by which MI could influence health behavior outcomes, it also highlights that more high quality research is needed, looking at other possible mechanisms or causal pathways within health behavior outcomes.

PRACTICE IMPLICATIONS

MI spirit possibly plays an important role within MI and may potentially be used to evoke change talk which links to outcomes.

Positive Psychological Interventions for Patients with Type 2 Diabetes: Rationale, Theoretical Model, and Intervention Development

Most patients with type 2 diabetes (T2D) have suboptimal adherence to recommended diet, physical activity, and/or medication. Current approaches to improve health behaviors in T2D have been variably effective, and successful interventions are often complex and intensive. It is therefore vital to develop interventions that are simple, well-accepted, and applicable to a wide range of patients who suffer from T2D. One approach may be to boost positive psychological states, such as positive affect or optimism, as these constructs have been prospectively and independently linked to improvements in health behaviors. Positive psychology (PP) interventions, which utilize systematic exercises to increase optimism, well-being, and positive affect, consistently increase positive states and are easily delivered to patients with chronic illnesses. However, to our knowledge, PP interventions have not been formally tested in T2D. In this paper, we review a theoretical model for the use of PP interventions to target health behaviors in T2D, describe the structure and content of a PP intervention for T2D patients, and describe baseline data from a single-arm proof-of-concept (N = 15) intervention study in T2D patients with or without depression. We also discuss how PP interventions could be combined with motivational interviewing (MI) interventions to provide a blended psychological-behavioral approach.

Effectiveness of a motivational interviewing intervention on medication compliance

This study investigated the effectiveness of training geriatric home-based primary care (HBPC) nursing staff in motivational interviewing (MI) techniques, with the goal of increasing patient medication adherence. Nursing staff received 4 hours of training in MI techniques from a licensed psychologist. Results indicated that the MI training increased medication adherence in the HBPC veteran sample by a small, but statistically significant, margin both 1 month and 6 months after the intervention. Although the effect size may be considered small, the clinical and cost ramifications of even a small gain in adherence are extremely important for the patient, clinician, and the medical facility. MI techniques may provide a cost-effective and impactful means of enhancing patient adherence to medications.

Nutritional status and its health-related factors among older adults in rural and urban areas

AIM

To compare health-related characteristics, nutrition-related factors and nutritional status of older adults living in rural and urban counties of Taiwan.

BACKGROUND

The older adult population of Taiwan is increasing. Furthermore, older people living in rural areas have shorter life expectancy and more chronic diseases than their urban counterparts. However, little is known about the health-related characteristics, nutrition-related factors and nutritional status of older adults living in rural and urban areas of Taiwan, limiting nurses' ability to identify and care for older adults at risk of poor nutritional health.

DESIGN

Cross-sectional, comparative.

METHODS

Older adults were randomly selected from names of residents of an adjacent rural and urban area of northern Taiwan and having completing the 2009 health evaluation. From March-July 2010, older adult participants (N = 366) provided data on demographic and health-related information, nutritional self-efficacy, health locus of control and nutritional status. Data were analysed by descriptive statistics and compared using chi-square and t-test.

RESULTS

Older rural participants had significantly lower educational level, less adequate income, higher medication use, lower scores on self-rated health status and researcher-rated health status and lower self-rated healthy eating status than their urban counterparts. Moreover, rural participants had significantly lower nutritional self-efficacy, higher chance health locus of control and poorer nutritional status than their urban counterparts.

CONCLUSIONS

Our results suggest that nurses should assess older adults living in rural areas for nutritional health and nutrition knowledge. Based on this assessment, nurses should develop easy, practical and accessible nutritional programmes for this population.

The potential for motivational interviewing to improve outcomes in the management of diabetes and obesity in paediatric and adult populations: a clinical review

Having good intentions to engage in healthy behaviours, to change our lives in a positive direction and make substantial, lasting changes may not always translate into actions or behaviour that is maintained. Motivational Interviewing is a directive person-centred approach designed to explore ambivalence and activate motivation for change [Miller WR, Rollnick S. Motivational Interviewing: Preparing People to Change Addictive Behaviour. London: Guilford Press, 1991]. A key component of a motivational interviewing conversation is to acknowledge that clients have every right to make no change. It uses a guiding communication style which invites people to consider their own situation and find their own solutions to situations that they identify as problematic that are preventing change. Motivational Interviewing was first introduced in adult health addiction services in the early 1980s. It has developed in the physical health specialties, and in the last 20 years or so attention has turned to the potential of Motivational Interviewing in the paediatric setting and the challenges of using it in families with children at differing ages and developmental stages. This article summarizes studies published from 2006 to 2011 of Motivational Interviewing in individuals across the lifespan with type 1 and type 2 diabetes and obesity.

Remote and web 2.0 interventions for promoting physical activity

BACKGROUND

Remote and web 2.0 interventions for promoting physical activity (PA) are becoming increasingly popular but their ability to achieve long term changes are unknown.

OBJECTIVES

To compare the effectiveness of remote and web 2.0 interventions for PA promotion in community dwelling adults (aged 16 years and above) with a control group exposed to placebo or no or minimal intervention.

SEARCH METHODS

We searched CENTRAL, MEDLINE, EMBASE, CINAHL, and some other databases (from earliest dates available to October 2012). Reference lists of relevant articles were checked. No language restrictions were applied.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that compared remote and web 2.0 PA interventions for community dwelling adults with a placebo or no or minimal intervention control group. We included studies if the principal component of the intervention was delivered using remote or web 2.0 technologies (for example the internet, smart phones) or more traditional methods (for example telephone, mail-outs), or both. To assess behavioural change over time, the included studies had a minimum of 12 months follow-up from the start of the intervention to the final results. We excluded studies that had more than a 20% loss to follow-up if they did not apply an intention-to-treat analysis.

DATA COLLECTION AND ANALYSIS

At least two authors independently assessed the quality of each study and extracted the data. Non-English language papers were reviewed with the assistance of an interpreter who was an epidemiologist. Study authors were contacted for additional information where necessary. Standardised mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for the continuous measures of self-reported PA and cardio-respiratory fitness. For studies with dichotomous outcomes, odds ratios and 95% CIs were calculated.

MAIN RESULTS

A total of 11 studies recruiting 5862 apparently healthy adults met the inclusion criteria. All of the studies took place in high-income countries. The effect of the interventions on cardiovascular fitness at one year (two studies; 444 participants) was positive and moderate with significant heterogeneity of the observed effects (SMD 0.40; 95% CI 0.04 to 0.76; high quality evidence). The effect of the interventions on self-reported PA at one year (nine studies; 4547 participants) was positive and moderate (SMD 0.20; 95% CI 0.11 to 0.28; moderate quality evidence) with heterogeneity (I2 = 37%) in the observed effects. One study reported positive results at two years (SMD 0.20; 95% CI 0.08 to 0.32; moderate quality evidence). When studies were stratified by risk of bias, the studies at low risk of bias (eight studies; 3403 participants) had an increased effect (SMD 0.28; 95% CI 0.16 to 0.40; moderate quality evidence). The most effective interventions applied a tailored approach to the type of PA and used telephone contact to provide feedback and to support changes in PA levels. There was no evidence of an increased risk of adverse events (seven studies; 2892 participants). Risk of bias was assessed as low (eight studies; 3060 participants) or moderate (three studies; 2677 participants). There were no differences in effectiveness between studies using different types of professionals delivering the intervention (for example health professional, exercise specialist). There was no difference in pooled estimates between studies that generated the prescribed PA using an automated computer programme versus a human, nor between studies that used pedometers as part of their intervention compared to studies that did not.

AUTHORS' CONCLUSIONS

We found consistent evidence to support the effectiveness of remote and web 2.0 interventions for promoting PA. These interventions have positive, moderate sized effects on increasing self-reported PA and measured cardio-respiratory fitness, at least at 12 months. The effectiveness of these interventions was supported by moderate and high quality studies. However, there continues to be a paucity of cost effectiveness data and studies that include participants from varying socioeconomic or ethnic groups. To better understand the independent effect of individual programme components, longer term studies, with at least one year follow-up, are required.

Face-to-face interventions for promoting physical activity

BACKGROUND

Face-to-face interventions for promoting physical activity (PA) are continuing to be popular but their ability to achieve long term changes are unknown.

OBJECTIVES

To compare the effectiveness of face-to-face interventions for PA promotion in community dwelling adults (aged 16 years and above) with a control exposed to placebo or no or minimal intervention.

SEARCH METHODS

We searched CENTRAL, MEDLINE, EMBASE, CINAHL, and some other databases (from earliest dates available to October 2012). Reference lists of relevant articles were checked. No language restrictions were applied.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that compared face-to-face PA interventions for community dwelling adults with a placebo or no or minimal intervention control group. We included studies if the principal component of the intervention was delivered using face-to-face methods. To assess behavioural change over time the included studies had a minimum of 12 months follow-up from the start of the intervention to the final results. We excluded studies that had more than a 20% loss to follow-up if they did not apply an intention-to-treat analysis.

DATA COLLECTION AND ANALYSIS

At least two authors independently assessed the quality of each study and extracted data. Non-English language papers were reviewed with the assistance of an interpreter who was an epidemiologist. Study authors were contacted for additional information where necessary. Standardised mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for continuous measures of self-reported PA and cardio-respiratory fitness. For studies with dichotomous outcomes, odds ratios (ORs) and 95% CIs were calculated.

MAIN RESULTS

A total of 10 studies recruiting 6292 apparently healthy adults met the inclusion criteria. All of the studies took place in high-income countries. The effect of interventions on self-reported PA at one year (eight studies; 6725 participants) was positive and moderate with significant heterogeneity (I² = 74%) (SMD 0.19; 95% CI 0.06 to 0.31; moderate quality evidence) but not sustained in three studies at 24 months (4235 participants) (SMD 0.18; 95% CI -0.10 to 0.46). The effect of interventions on cardiovascular fitness at one year (two studies; 349 participants) was positive and moderate with no significant heterogeneity in the observed effects (SMD 0.50; 95% CI 0.28 to 0.71; moderate quality evidence). Three studies (3277 participants) reported a positive effect on increasing PA levels when assessed as a dichotomous measure at 12 months, but this was not statistically significant (OR 1.52; 95% CI 0.88 to 2.61; high quality evidence). Although there were limited data, there was no evidence of an increased risk of adverse events (one study; 149 participants). Risk of bias was assessed as low (four studies; 4822 participants) or moderate (six studies; 1543 participants). Any conclusions drawn from this review require some caution given the significant heterogeneity in the observed effects. Despite this, there was some indication that the most effective interventions were those that offered both individual and group support for changing PA levels using a tailored approach. The long term impact, cost effectiveness and rates of adverse events for these interventions was not established because the majority of studies stopped after 12 months.

AUTHORS' CONCLUSIONS

Although we found evidence to support the effectiveness of face-to-face interventions for promoting PA, at least at 12 months, the effectiveness of these interventions was not supported by high quality studies. Due to the clinical and statistical heterogeneity of the studies, only limited conclusions can be drawn about the effectiveness of individual components of the interventions. Future studies should provide greater detail of the components of interventions, and assess impact on quality of life, adverse events and economic data.

Face-to-face versus remote and web 2.0 interventions for promoting physical activity

BACKGROUND

Face-to-face interventions for promoting physical activity (PA) are continuing to be popular as remote and web 2.0 approaches rapidly emerge, but we are unsure which approach is more effective at achieving long term sustained change.

OBJECTIVES

To compare the effectiveness of face-to-face versus remote and web 2.0 interventions for PA promotion in community dwelling adults (aged 16 years and above).

SEARCH METHODS

We searched CENTRAL, MEDLINE, EMBASE, CINAHL, and some other databases (from earliest dates available to October 2012). Reference lists of relevant articles were checked. No language restrictions were applied.

SELECTION CRITERIA

Randomised trials that compared face-to-face versus remote and web 2.0 PA interventions for community dwelling adults. We included studies if they compared an intervention that was principally delivered face-to-face to an intervention that had principally remote and web 2.0 methods. To assess behavioural change over time, the included studies had a minimum of 12 months follow-up from the start of the intervention to the final results. We excluded studies that had more than a 20% loss to follow-up if they did not apply an intention-to-treat analysis.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed the quality of each study and extracted the data. Non-English language papers were reviewed with the assistance of an interpreter who was an epidemiologist. Study authors were contacted for additional information where necessary. Standardised mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for continuous measures of cardio-respiratory fitness.

MAIN RESULTS

One study recruiting 225 apparently healthy adults met the inclusion criteria. This study took place in a high-income country. From 27,299 hits, the full texts of 193 papers were retrieved for examination against the inclusion criteria. However, there was only one paper that met the inclusion criteria. This study reported the effect of a PA intervention on cardio-respiratory fitness. There were no reported data for PA, quality of life, or cost effectiveness. The difference between the remote and web 2.0 versus face-to-face arms was not significant (SMD -0.02; 95% CI -0.30 to 0.26; high quality evidence). The risk of bias in the included study was assessed as low, and there was no evidence of an increased risk of adverse events.

AUTHORS' CONCLUSIONS

There is insufficient evidence to assess whether face-to-face interventions or remote and web 2.0 approaches are more effective at promoting PA.

Physical activity interventions differentially affect exercise task and barrier self-efficacy: a meta-analysis

OBJECTIVE

Researchers have yet to establish how interventions to increase physical activity influence specific self-efficacy beliefs. The current study sought to quantify the effect of interventions to increase physical activity among healthy adults on exercise task (EXSE) and barrier self-efficacy (BSE) via meta-analysis. Intervention characteristics associated with self-efficacy and physical activity changes were also identified.

METHODS

A systematic database search and manual searches through reference lists of related publications were conducted for articles on randomized, controlled physical activity interventions. Published intervention studies reporting changes in physical activity behavior and either EXSE or BSE in healthy adults were eligible for inclusion.

RESULTS

Of the 1,080 studies identified, 20 were included in the meta-analyses. Interventions had a significant effect of g = 0.208, 95% confidence interval (CI) [0.027, 0.388], p < .05, on EXSE; g = 0.128, 95% CI [0.05, 0.20], p < .05 on BSE; and g = 0.335 95% CI [0.196, 0.475], p < .001, on physical activity. Moderator analyses indicated shorter interventions that did not include structured exercise sessions effectively increased EXSE and physical activity, whereas long interventions improved BSE. Interventions that did not provide support increased BSE and physical activity levels. Further, interventions that did not require the use of daily exercise logs improved EXSE and physical activity behavior.

CONCLUSION

Interventions designed to increase physical activity differentially influenced EXSE and BSE. EXSE appeared to play a more significant role during exercise adoption, whereas BSE was involved in the maintenance of exercise behavior. Recommendations are offered for the design of future interventions.

Community-based efforts to promote physical activity: a systematic review of interventions considering mode of delivery, study quality and population subgroups

OBJECTIVES

Despite the known benefits of physical activity, the majority of adults in developed countries lead sedentary lifestyles. The community setting is a promising venue for physical activity-promoting interventions. Our objectives were to investigate the effectiveness of community-based physical activity interventions by mode of delivery, study quality and to analyse intervention effectiveness in different subgroups in the population.

DESIGN

We conducted a systematic literature review in Medline and other databases to identify controlled, community-based physical activity interventions published between 2001 and 2012.

METHODS

We performed several post hoc subgroup comparisons for mode of delivery, study quality and selected population characteristics, using net per cent change in physical activity outcomes between baseline and follow-up as an effect measure.

RESULTS

We identified 55 studies on exercise/walking sessions, face-to-face counselling, public campaigns and interventions by mail, the Internet and telephone presenting data on 20,532 participants. Overall, half of the studies reported positive physical activity outcomes (total net per cent change: 16.4%; p=0.159; net per cent change for high-quality studies, i.e. studies meeting more than 5 out of 7 quality criteria: 16.2%; p=0.010). Interventions using face-to-face counselling or group sessions were most effective (net per cent change: 35.0%; p=0.014). Net per cent change was also higher in studies exclusively tailored to women (27.7%; p=0.005) or specific ethnic groups (38.9%; p=0.034).

CONCLUSIONS

This systematic review supports the effectiveness of community-based physical activity interventions in high-quality studies. Our results suggest that interventions using personal contact as well as tailored interventions are most promising.

Using meta-analyses for comparative effectiveness research

Comparative effectiveness research seeks to identify the most effective interventions for particular patient populations. Meta-analysis is an especially valuable form of comparative effectiveness research because it emphasizes the magnitude of intervention effects rather than relying on tests of statistical significance among primary studies. Overall effects can be calculated for diverse clinical and patient-centered variables to determine the outcome patterns. Moderator analyses compare intervention characteristics among primary studies by determining whether effect sizes vary among studies with different intervention characteristics. Intervention effectiveness can be linked to patient characteristics to provide evidence for patient-centered care. Moderator analyses often answer questions never posed by primary studies because neither multiple intervention characteristics nor populations are compared in single primary studies. Thus, meta-analyses provide unique contributions to knowledge. Although meta-analysis is a powerful comparative effectiveness strategy, methodological challenges and limitations in primary research must be acknowledged to interpret findings.

Motivational interviewing may improve exercise experience for people with multiple sclerosis: A small randomized trial

People with multiple sclerosis (MS) are likely to benefit from regular exercise, but physical inactivity is more common among people with MS than among the general population. This small randomized study evaluated whether motivational interviewing (MI) affects adherence to and personal experience in an exercise program. Inactive people with MS participating in an eight-week exercise program were randomized to either three brief MI (n = 7) or three health coaching (n = 6) sessions. Session attendance for both conditions was high, and MI fidelity was rigorously and reliably measured using the Motivational Interviewing Treatment Integrity Scales. The feasibility of using this approach was demonstrated with a small sample. Large effects favoring the MI condition were found for physical exertion, affect during exercise, and fatigue, but no effects were found for adherence to the exercise program. Treatment integrity measures of MI were correlated with outcomes in expected directions. Although this study demonstrated the feasibility of this MI approach, the large effect sizes found should be viewed with substantial skepticism and replicated in sufficiently powered studies using objective measures of exercise adherence.

The effectiveness of a motivational interviewing primary-care based intervention on physical activity and predictors of change in a disadvantaged community

Little research exists on the impact of behavior change interventions in disadvantaged communities. We conducted a prospective study to explore the effectiveness of motivational interviewing on physical activity change within a deprived community and the social- psychological and motivational predictors of change in physical activity including stage of change, self-efficacy, social support, and variables from self-determination theory and the theory of planned behavior. Five motivational interviewing counsellors recruited 207 patients and offered motivational interviewing sessions to support physical activity behavior change. At 6-months there were significant improvements in physical activity, stage of change, and social support. A dose-response relationship was evident; those who attended 2 or more consultations increased their total physical activity, stage of change and family social support more than those who attended just one. Hierarchical regression analyses indicated that number of sessions and change in stage of change predicted 28.4% of the variance in change in total physical activity and, with social support from friends, 21.0% of the variance in change walking time. Change in perceived behavioral control and attitudes, friend social support, and number of sessions predicted 16.8% of the variance in change in vigorous physical activity. Motivational interviewing is an effective approach for promoting physical activity amongst lower socio-economic status groups in the short term. The study demonstrates good translational efficacy, and contributes to a limited number of physical activity interventions targeting low income groups in the UK.

Telephone-delivered interventions for physical activity and dietary behavior change: an updated systematic review

CONTEXT

Telephone-delivered interventions targeting physical activity and dietary change have potential for broad population reach and thus have a role to play in addressing increasing rates of lifestyle-related chronic diseases. The purpose of this systematic review is to update the evidence for their potential to inform translation, including effectiveness in promoting maintenance, reporting on implementation, and costs.

EVIDENCE ACQUISITION

A structured search of PubMed, MEDLINE, and PsycINFO (January 2006 to April 2010) was conducted. Included studies reported on physical activity and/or dietary change in adults, delivered at least 50% of intervention contacts by telephone, and included a control group (except in dissemination studies). Detailed information on study design, intervention features, and behavioral outcomes was extracted, tabulated, and summarized.

EVIDENCE SYNTHESIS

Twenty-five studies (27 comparisons) were included: 16 for physical activity, two for diet, and seven for combined interventions. Twenty of 27 comparisons found evidence for initiation of behavior change (14 of 17 comparisons for physical activity; two of two for diet; four of eight for combined interventions). Ten of 25 studies evaluated post-intervention maintenance of change, with three reporting that maintenance was achieved for at least 50% of outcomes. Dissemination studies were rare (n=3), as were dose-response (n=2) and cost-effectiveness analyses (n=2).

CONCLUSIONS

Given the strength of evidence for telephone-delivered physical activity and dietary change interventions, greater emphasis on dissemination studies is warranted.

Facilitating adherence to physical activity: exercise professionals' experiences of the National Exercise Referral Scheme in Wales: a qualitative study

Background

Although implementers' experiences of exercise referral schemes (ERS) may provide valuable insights into how their reach and effectiveness might be improved, most qualitative research has included only views of patients. This paper explores exercise professionals' experiences of engaging diverse clinical populations in an ERS, and emergence of local practices to support uptake and adherence in the National Exercise Referral Scheme (NERS) in Wales.

Methods

Thirty-eight exercise professionals involved in the delivery of NERS in 12 local health board (LHB) areas in Wales took part in a semi-structured telephone interview. Thematic analysis was conducted.

Results

Professionals' accounts offered insights into how perceived needs and responses to NERS varied by patient characteristics. Adherence was described as more likely where the patient sought referral from a health professional rather than being advised to attend. Hence, professionals sometimes described a need for the referral process to identify patients for whom change was already internally motivated. In addition, mental health patients were seen as facing additional barriers, such as increased anxieties about the exercise environment. Professionals described their role as involving helping patients to overcome anxieties about the exercise environment, whilst providing education and interpersonal support to assist patients' confidence and motivation. However, some concerns were raised regarding the levels of support that the professional should offer whilst avoiding dependence. Patient-only group activities were described as supporting adherence by creating an empathic environment, social support and modelling. Furthermore, effectively fostering social support networks was identified as a key mechanism for reducing dependence and maintaining changes in the longer term.

Conclusions

Whether ERS should identify motivated patients, or incorporate activities to support internalisation of motivation amongst less motivated patients deserves attention. As well as providing the knowledge to advise patients on how to exercise safely given their conditions, professionals' training should focus on providing the skills to meet the interpersonal support needs of patients, particularly where ERS are used as a means of improving mental health outcomes. The effectiveness of emerging activities, such as post-scheme maintenance classes, in fostering long-term social networks supportive of physical activity deserve attention.

Integration of motivational interviewing into practice in the national exercise referral scheme in Wales: a mixed methods study

BACKGROUND

Though motivational interviewing (MI) has demonstrated efficacy in a range of behaviour change settings, effectiveness will require successful integration into everyday practice. This study examines implementers' views on delivering MI within an exercise referral scheme and consistency of consultations with MI before and after a 2-day workshop.

METHOD

Semi-structured interviews were conducted with 27 exercise professionals and 10 area coordinators delivering the Welsh National Exercise Referral Scheme (NERS), and the MI trainer. Eleven professionals provided consultation recordings before and 6-months after training, coded for fidelity using the Behaviour Change Counselling Index.

RESULTS

The workshop was well received by most, triggering increased recognition of potential motivational roles of consultations. However, some cited difficulties combining MI with structured data gathering activities, whilst a minority rejected MI, seeing current practice as effective, or MI as unnecessary because patients were ready to change. Although limited aggregate improvement in practice was observed, substantial improvements were observed in some individuals. Comments on the need for further practice or training were widespread.

CONCLUSIONS

Efforts to implement MI should ensure that training and structures to provide monitoring and feedback are in place and that activities incorporated within consultations are compatible with MI delivery.

Group motivational interviewing to promote adherence to antiretroviral medications and risk reduction behaviors in HIV infected women

We present the results of a clinical trial that tested the efficacy of using motivational interviewing (MI) in a group format to promote adherence to antiretroviral medications and risk reduction behaviors (RRB) in 203 predominately African American HIV infected women. It was compared to a group health promotion program. Participants were followed for 9 months. Adherence was measured by MEMS(®); and RRB by self-report. Controlling for recruitment site and years on ART, no significant group by time effects were observed. Attendance (≥7/8 sessions) modified the effects. Higher MI attendees had better adherence at all follow-ups, a borderline significant group by time effect (p = 0.1) for % Doses Taken on Schedule, a significantly larger proportion who reported abstinence at 2 weeks, 6, and 9 months, and always used protection during sex at 6 and 9 months. Though not conclusive, the findings offer some support for using MI in a group format to promote adherence and some risk reduction behaviors when adequate attendance is maintained.

Suboptimal Exercise Compliance: Common Barriers to an Active Lifestyle and Counseling Strategies to Overcome Them

Adherence to a structured exercise program provides numerous health benefits, including reductions in body weight, fat stores, and blood pressure, improved blood glucose management and lipid/lipoprotein profiles, increased cardiorespiratory fitness, decreased cardiovascular risk, and enhanced psychosocial well-being. Despite these benefits, many individuals find it difficult to comply with a regular exercise program, predisposing them to an increased risk of chronic diseases and other medical conditions. Several barriers to participation in structured exercise, including time and financial constraints, psychosocial factors, and physical limitations, contribute to low adherence rates. Accordingly, health care professionals should use varied counseling strategies to assist their patients in overcoming habitual physical inactivity and our increasingly hypokinetic lifestyle. Motivational interviewing, goal setting, using stages of readiness to change, and identifying physical/psychosocial limitations are effective ways for helping patients to achieve the health and fitness benefits of structured exercise, increased lifestyle physical activity, or both.

Firm foundations: strength-based approaches to adolescent chronic disease

PURPOSE OF REVIEW

Chronic disease management is an increasingly important aspect of caring for adolescents. Strength-based approaches hold tremendous promise in the face of current challenges. Recent clinical innovations and research findings that provide evidence of the efficacy of strength-based approaches and represent a fundamental evolution in the clinical approach to adolescent care are reviewed.

RECENT FINDINGS

Resilience and positive youth development are important conceptual frameworks in adolescent health, which have recently been brought into the clinic setting in the form of the strength-based approach to care. In parallel, studies of motivational interviewing, a strength-based technique with known efficacy in behavioral change, have begun to demonstrate clinical efficacy in various adolescent chronic disease applications. The coupling of a strength-based approach with motivational interviewing holds promise for not only modifying end behaviors but also helping teens to develop strengths and assets to promote general well-being and healthy development. This distinction in goals might be described as the difference between being transiently problem-free and durably problem-resistant.

SUMMARY

Strength-based approaches, including motivational interviewing, hold tremendous potential for equipping providers to address the rapidly increasing burden of chronic disease in adolescents.

Effects of the built environment on physical activity of adults living in rural settings

OBJECTIVE

To conduct a systematic review of the literature to examine the influence of the built environment (BE) on the physical activity (PA) of adults in rural settings.

DATA SOURCE

Key word searches of Academic Search Premier, PubMed, CINAHL, Web of Science, and Sport Discus were conducted.

STUDY INCLUSION AND EXCLUSION CRITERIA

Studies published prior to June 2008 were included if they assessed one or more elements of the BE, examined relationships between the BE and PA, and focused on rural locales. Studies only reporting descriptive statistics or assessing the reliability of measures were excluded.

DATA EXTRACTION

Objective(s), sample size, sampling technique, geographic location, and definition of rural were extracted from each study. Methods of assessment and outcomes were extracted from the quantitative literature, and overarching themes were identified from the qualitative literature.

DATA SYNTHESIS

Key characteristics and findings from the data are summarized in Tables 1 through 3.

RESULTS

Twenty studies met inclusion and exclusion criteria. Positive associations were found among pleasant aesthetics, trails, safety/crime, parks, and walkable destinations.

CONCLUSIONS

Research in this area is limited. Associations among elements of the BE and PA among adults appear to differ between rural and urban areas. Considerations for future studies include identifying parameters used to define rural, longitudinal research, and more diverse geographic sampling. Development and refinement of BE assessment tools specific to rural locations are also warranted.

Mediators of physical activity behaviour change among adult non-clinical populations: a review update

BACKGROUND

An understanding of the determinants of physical activity through mediators of behaviour change is important in order to evaluate the efficacy of interventions. Prior reviews on this topic noted that few studies employed mediator analyses in experimental physical activity trials; the purpose of this review is to update these prior reviews in order to evaluate the state of our present understanding of interventions that include proposed mediators of behaviour change.

METHODS

Literature was identified through electronic database (e.g., MEDLINE, psychINFO) searching. Studies were eligible if they described a published experimental or quasi-experimental trial examining the effect of an intervention on physical activity behaviour and mediator change in non-clinical adult populations. Quality of included studies was assessed and the analyses examined the symmetry between mediators and behaviour change.

RESULTS

Twenty seven unique trials passed the eligibility criteria and 22 were included in the analysis with scores of moderate or higher quality. Half of the studies reviewed failed to show an intervention effect on PA. The remaining studies showed evidence that the intervention affected changes in the proposed mediators, but tests of mediated effect were performed in only six of these 11 cases and demonstrated mixed outcomes. Differences by theory were not discernable at this time, but self-regulation constructs had the most evidence for mediation.

CONCLUSION

Published literature employing mediators of change analyses in experimental designs is still relatively elusive since the time of prior reviews; however, the general null findings of changes in mediating constructs from these interventions are a more timely concern. Changes in self-regulation constructs may have the most effect on changes in PA while self-efficacy and outcome expectation type constructs have negligible but limited findings. Innovation and increased fidelity of interventions is needed and should be a priority for future research.

Review of Motivational Interviewing in promoting health behaviors

There is considerable evidence for the effectiveness of Motivational Interviewing (MI) in the treatment of substance abuse, as well as a number of other health behavior areas. The present paper summarizes and critically reviews the research in three emerging areas in which (MI) is being applied: diet and exercise, diabetes, and oral health. Although 10 prior reviews focused in part on MI studies in the areas of diet, exercise, or diabetes, the present paper provides an up-to-date review, and includes oral health as another emerging area of MI research. Overall, 37 articles were reviewed: 24 in the areas of diet and exercise, 9 in the area of diabetes, and 4 in the oral health area. Research in these areas suggests that (MI) is effective in all these health domains, although additional research is needed, particularly in the oral health arena. Specifically, future research in the areas of diet and exercise should examine the clinical utility of MI by health care professionals (other than dietitians), studies in the area of diabetes should continue to examine long-term effects of MI on glycemic control, and research in the area of oral health should focus on developing additional trials in this field. Further, future studies should demonstrate improved research methodology, and investigate the effects of possible outcome mediators, such as client change talk, on behavior change.

Cost-utility of a walking programme for moderately depressed, obese, or overweight elderly women in primary care: a randomised controlled trial

Background

There is a considerable public health burden due to physical inactivity, because it is a major independent risk factor for several diseases (e.g., type 2 diabetes, cardiovascular disease, moderate mood disorders neurotic diseases such as depression, etc.). This study assesses the cost utility of the adding a supervised walking programme to the standard "best primary care" for overweight, moderately obese, or moderately depressed elderly women.

Methods

One-hundred six participants were randomly assigned to an interventional group (n = 55) or a control group (n = 51). The intervention consisted of an invitation, from a general practitioner, to participate in a 6-month walking-based, supervised exercise program with three 50-minute sessions per week. The main outcome measures were the healthcare costs from the Health System perspective and quality adjusted life years (QALYs) using EuroQol (EQ-5D.)

Results

Of the patients invited to participate in the program, 79% were successfully recruited, and 86% of the participants in the exercise group completed the programme. Over 6 months, the mean treatment cost per patient in the exercise group was €41 more than "best care". The mean incremental QALY of intervention was 0.132 (95% CI: 0.104–0.286). Each extra QALY gained by the exercise programme relative to best care cost €311 (95% CI, €143–€394). The cost effectiveness acceptability curves showed a 90% probability that the addition of the walking programme is the best strategy if the ceiling of inversion is €350/QALY.

Conclusion

The invitation strategy and exercise programme resulted in a high rate of participation and is a feasible and cost-effective addition to best care. The programme is a cost-effective resource for helping patients to increase their physical activity, according to the recommendations of general practitioners. Moreover, the present study could help decision makers enhance the preventive role of primary care and optimize health care resources.
