Using Positive Psychology to Address Emotional Barriers to Physical Activity After Bariatric Surgery: Proof-of-Concept Trial of the Gaining Optimism After Weight Loss Surgery (GOALS) Project.

Physical activity promotes health and longevity after metabolic/bariatric surgery (MBS), but most patients do not meet recommended levels. The Gaining Optimism After weight Loss Surgery (GOALS) Project was a positive psychological intervention designed to address common emotional barriers to physical activity in patients who have recently undergone MBS (e.g., low confidence around exercise, internalized weight bias, fear of injury) and use motivational interviewing and standard behavior change techniques (e.g., self-monitoring) to increase physical activity. This single-arm proof-of-concept trial was designed to refine the intervention, test feasibility and acceptability, and explore pre-post changes in behavioral and psychological outcomes. Participants were 12 adults 6-12 months post-MBS (M age of 46, 58% female, 67% non-Hispanic white). GOALS was a 10-week telephone counseling program that introduced new positive psychological skills and physical activity topics each week. Participants tracked physical activity with a Fitbit and set weekly goals. Results showed that the intervention was feasible (85% of sessions completed) and acceptable (average participant ratings of session ease and utility above 8.0 on a 0-10 scale). There were medium-to-large effect size improvements in physical activity and psychological well-being (e.g., depressive symptoms). The GOALS intervention will next be tested in a pilot randomized controlled trial with longer-term follow-up to assess its effect more robustly.

Can positive psychological interventions improve health behaviors? A systematic review of the literature.

Positive psychological interventions (PPIs), which aim to cultivate psychological well-being, have the potential to improve health behavior adherence. This systematic review summarized the existing literature on PPI studies with a health behavior outcome to examine study methodology, quality, and efficacy. Of the 27 identified studies, 20 measured physical activity, eight measured medication adherence, seven measured diet, and three measured smoking (eight targeted multiple behaviors). Twenty studies were randomized controlled trials (RCTs; 13 fully powered), and seven had a single-arm design. Study samples were usually adults (n = 21), majority non-Hispanic white (n = 15) and female (n = 14), and with a specific disease (e.g., diabetes, n = 16). Most interventions combined a PPI with health behavior-focused content (n = 17), used a remote delivery method (n = 17), and received a moderate or low study quality rating. Overall, 19/27 studies found a health behavior improvement of at least medium effect size, while six of the 13 studies powered to detect significant effects were statistically significant. Of the behaviors measured, physical activity was most likely to improve (14/20 studies). In summary, PPIs are being increasingly studied as a strategy to enhance health behavior adherence. The existing literature is limited by small sample size, low study quality and inconsistent intervention content and outcome measurement. Future research should establish the most effective components of PPIs that can be tailored to different populations, use objective health behavior measurement, and robustly examine the effects of PPIs on health behaviors in fully powered RCTs.

A Positive Psychology-Motivational Interviewing Intervention to Promote Positive Affect and Physical Activity in Type 2 Diabetes: The BEHOLD-8 Controlled Clinical Trial.

OBJECTIVE: Physical activity is associated with superior health outcomes in patients with type 2 diabetes (T2D), but most T2D patients do not follow physical activity recommendations. The objective of this study was to assess the feasibility and impact of a novel combined positive psychology-motivational interviewing (PP-MI) intervention to promote physical activity in T2D. METHODS: This controlled clinical trial compared an 8-week, phone-delivered PP-MI intervention to an attention-matched MI-enhanced behavioral counseling condition among 60 participants with T2D and suboptimal moderate to vigorous physical activity (MVPA; <150 min/wk). The primary study outcome was feasibility (proportion of sessions completed) and acceptability (0-10 ease and utility ratings of each session). Secondary outcomes were between-group differences in changes in positive affect (main psychological outcome) and accelerometer-measured physical activity (MVPA and steps per day), using mixed-effects regression models, at 8 and 16 weeks. RESULTS: Ninety-two percent of PP-MI sessions were completed, and mean participant ratings of ease/utility were 8.5 to 8.8/10, surpassing a priori benchmarks for feasibility and acceptability. PP-MI participants had small-medium effect size (ES) difference improvements in positive affect compared with MI (8 weeks: estimated mean difference [EMD] = 3.07 [SE = 1.41], p = .029, ES = 0.44; 16 weeks: EMD = 2.92 [SE = 1.73], p = .092, ES = 0.42). PP-MI participants also had greater improvements in MVPA (8 weeks: EMD = 13.05 min/d [SE = 5.00], p = .009, ES = 1.24; 16 weeks: EMD = 7.96 [SE = 4.53], p = .079, ES = 0.75), with similar improvements in steps per day. CONCLUSIONS: The PP-MI intervention was feasible and well accepted. Next-step efficacy studies can more rigorously explore the intervention's effects on physical activity and clinical outcomes.

Developing a Psychological-Behavioral Intervention in Cardiac Patients Using the Multiphase Optimization Strategy: Lessons Learned From the Field.

BACKGROUND: The Multiphase Optimization Strategy (MOST) is an approach to systematically and efficiently developing a behavioral intervention using a sequence of experiments to prepare and optimize the intervention. PURPOSE: Using a 6 year MOST-based behavioral intervention development project as an example, we outline the results-and resulting decision-making process-related to experiments at each step to display the practical challenges present at each stage. METHODS: To develop a positive psychology (PP) based intervention to promote physical activity after an acute coronary syndrome (N = 255 across four phases), we utilized qualitative, proof-of-concept, factorial design, and randomized pilot experiments, with iterative modification of intervention content and delivery. RESULTS: Through this multiphase approach, we ultimately developed a 12 week, phone-delivered, combined PP-motivational interviewing intervention to promote physical activity. Across stages, we learned several important lessons: (a) participant and interventionist feedback is important, even in later optimization stages; (b) a thoughtful and systematic approach using all information sources is required when conflicting results in experiments make next steps unclear; and (3) new approaches in the field over a multiyear project should be integrated into the development process. CONCLUSIONS: A MOST-based behavioral intervention development program can be efficient and effective in developing optimized new interventions, and it may require complex and nuanced decision-making at each phase.

A Virtual Resiliency Intervention Promoting Resiliency for Parents of Children with Learning and Attentional Disabilities: A Randomized Pilot Trial.

OBJECTIVES: One in five children have a learning and attentional disability (LAD). Parents of children with LAD are vulnerable to distress, but an evidence-based treatment has not been developed. METHODS: From June 2016 to November 2017, we conducted a mixed methods study to adapt and assess the virtual delivery of a mind-body group resiliency program, the Stress Management and Resiliency Training-Relaxation Response Resiliency Program (SMART-3RP), to meet the needs of parents of children with LAD; this is an 8-session weekly group intervention. In the first phase, we conducted 4 parent focus group interviews, 2 professional focus group interviews, and 5 professional individual interviews, and 1 pilot group to adapt the SMART-3RP to target the needs of parents of children with LAD. In the second phase, we conducted a pilot wait-list controlled study to assess the feasibility, acceptability, and preliminary efficacy of a videoconferencing delivery of the adapted program. Parents were randomized to an immediate intervention group (IG) or wait-list control group (WC). Surveys were administered at baseline (time 1), end of intervention for the IG or 3 months post-baseline for the WC (time 2), and 3 months post treatment for the IG or end of intervention for the WC (time 3). RESULTS: Qualitative findings illustrated high levels of parental stress, with primary stressors including navigating the educational system, interactions with other parents, familial concerns, and financial and professional sacrifices. We adapted the manual to target these stressors and modified session logistics and delivery. Fifty-three parents (mean age = 46.8; 90.6% female) participated nationally in the pilot trial. 62.5% of participants completed ≥ 6/8 sessions; 81.8% reported continued daily/weekly relaxation response exercise practice. T1-T2 comparisons found that IG versus WC participants showed significant improvements in distress [VAS], ∆M = - 1.95; d = .83 and resilience [CES], ∆M = 6.38; d = .83, as well as stress coping [MOCS-A] ∆M = 8.69; d = 1.39; depression and anxiety [PHQ-4], ∆M = - 1.79; d = .71; social support [MOS-SSS], ∆M = 5.47; d = .71; and empathy [IRI], ∆M = 3.17; d = .77; improvements were sustained at the 3 month post intervention follow-up. CONCLUSION: Pilot wait-list randomized trial findings showed promising feasibility, acceptability, and preliminary efficacy for the SMART-3RP intervention adapted for parents of children with LAD. This virtually-delivered resiliency intervention improved parents' distress, resiliency, and stress coping, which were sustained. CLINICAL TRIALS ID: NCT02772432.

Positive psychological experiences in allogeneic hematopoietic stem cell transplantation.

OBJECTIVE: Positive psychological constructs (e.g., optimism and hope) have been associated with superior health outcomes in the recovery from hematopoietic stem cell transplantation (HSCT) in prior work. However, such studies have not examined a broad range of positive psychological constructs, their sources or evolution over time, or their connections with key health behaviors. We used semistructured qualitative interviews in 25 HSCT patients to explore the nature and sources of positive psychological experiences during the first 100 days after transplantation. METHODS: Participants completed interviews during their HSCT hospitalization and approximately 100 days after transplantation. Transcribed interviews were organized and analyzed using NVivo 12 software by two coders (κ = 0.92). Interviews focused on the breadth of positive psychological experiences, their sources and evolution during the 100 days, and participants' perceived impact of positive constructs on health behaviors. RESULTS: Several positive psychological constructs especially gratitude, determination, and optimism were frequently expressed. Family support and deliberate participation in pleasant and meaningful activities were the two primary sources of positive psychological experiences after HSCT. At baseline, participants consistently reported gratitude for their donors while follow-up was consistently characterized by hope for cure and return to baseline level of functioning. Additionally, participants related bidirectional relationships between positive psychological well-being experiences and completion of health behaviors over time. CONCLUSIONS: As one of the first qualitative studies characterizing the breadth, sources, and evolution of positive psychological experiences in HSCT patients, these findings add to the literature aimed at understanding psychological well-being in this complex and growing patient population.

Relationships Between Life Stressors, Health Behaviors, and Chronic Medical Conditions in Mid-Life Adults: A Narrative Review.

OBJECTIVES: (1) To explore stressors affecting midlife adults and understand their impact on health behaviors and the development of chronic medical conditions; (2) To identify midlife-specific interventions that mitigate the impact of stressors on the health of this population. METHODS: We searched the PubMed database from inception to December 2017 using the search terms [mid-life] and [midlife] paired with related behaviors and conditions. Eligible articles provided data on: (1) sources of stress and effects on health behaviors, (2) development of chronic medical conditions, or (3) midlife interventions targeting health-related stressors or behaviors. We also reviewed the references of articles found in the initial search to identify additional articles. We included studies not focused on midlife for comparison. RESULTS: This review revealed that interpersonal stress (e.g., caregiving and loneliness), occupational stress, and financial stress are highly prevalent in midlife and have a substantial impact on the health and health behaviors of this population. Many of these stressors converge, intensifying associated distress and health impact. Although not always targeted specifically to this population, interventions focused on diminishing these stressors have showed promising results, particularly group interventions and those focused on positive psychological well-being and mindfulness. CONCLUSION: Midlife is a large and growing population at high risk for chronic medical conditions. Specific stressors during this period are negatively associated with health outcomes. Further research is needed on midlife-specific interventions focused on mitigating these stressors, as such interventions have the potential to improve quality of life and promote health in this significant and vulnerable segment of society.

Psychological well-being as part of the public health debate? Insight into dimensions, interventions, and policy.

BACKGROUND: Increasing evidence suggests that psychological well-being (PWB) is associated with lower disease and mortality risk, and may be enhanced with relatively low-cost interventions. Yet, dissemination of these interventions remains limited, in part because insufficient attention has been paid to distinct PWB dimensions, which may impact physical health outcomes differently. METHODS: This essay first reviews the empirical evidence regarding differential relationships between all-cause mortality and multiple dimensions of PWB (e.g., life purpose, mastery, positive affect, life satisfaction, optimism). Then, individual-level positive psychology interventions aimed at increasing PWB and tested in randomized-controlled trials are reviewed as these allow for easy implementation and potentially broad outreach to improve population well-being, in concert with efforts targeting other established social determinants of health. RESULTS: Several PWB dimensions relate to mortality, with varying strength of evidence. Many of positive psychology trials indicate small-to-moderate improvements in PWB; rigorous institution-level interventions are comparatively few, but preliminary results suggest benefits as well. Examples of existing health policies geared towards the improvement of population well-being are also presented. Future avenues of well-being epidemiological and intervention research, as well as policy implications, are discussed. CONCLUSIONS: Although research in the fields of behavioral and psychosomatic medicine, as well as health psychology have substantially contributed to the science of PWB, this body of work has been somewhat overlooked by the public health community. Yet, the growing interest in documenting well-being, in addition to examining its determinants and consequences at a population level may provoke a shift in perspective. To cultivate optimal well-being-mental, physical, social, and spiritual-consideration of a broader set of well-being measures, rigorous studies, and interventions that can be disseminated is critically needed.

A positive psychology-motivational interviewing intervention for patients with type 2 diabetes: Proof-of-concept trial.

OBJECTIVE: Eighteen million Americans with type 2 diabetes (T2D) do not follow recommended guidelines for physical activity. Motivational interviewing (MI) has had modest effects on activity and related behaviors in T2D. Positive psychological attributes (e.g., optimism) are associated with superior medical outcomes in T2D, and positive psychology (PP) interventions promote such attributes. There had been no study in T2D of a combined PP-MI intervention to promote well-being and health behavior adherence. We developed a novel, telephone-delivered, 16-week PP-MI intervention and explored its feasibility and impact in T2D patients in a single-arm, proof-of-concept trial. METHOD: Participants completed PP-based exercises and MI-based physical activity goal-setting activities and reviewed these activities weekly with a study trainer for 16 weeks. Feasibility and acceptability were assessed via exercise completion rates and post-exercise ratings of ease/utility (0-10 scales). Impact was explored by examining changes in physical activity (via accelerometers and self-report), other health behaviors, psychological measures, and medical outcomes (e.g., hemoglobin A1c (A1C)) from baseline to 16 weeks, using paired t tests. RESULTS: Twelve participants enrolled, and 10 provided follow-up data. Seventy-eight percent of PP-MI activities were completed, and participants rated the PP-MI content and sessions as easy (mean = 8.2/10, standard deviation (SD) = 1.9) and useful (mean = 9.1/10, SD = 1.5). PP-MI was associated with improved adherence to health behaviors and overall self-care, variable effects on accelerometer-measured activity and psychological outcomes, and modest beneficial effects on body mass index and A1C. CONCLUSION: Further testing of this intervention is warranted in a larger, controlled trial to assess its effects on important health outcomes.

The role of spousal support for dietary adherence among type 2 diabetes patients: a narrative review.

Healthy eating is key to successful management of type 2 diabetes (T2D). As discussed in this narrative review, there are strong indications that spousal support is an important element affecting dietary adherence in T2D. To provide a synthesized review of this evidence, Google Scholar and PubMed were searched, 28 relevant studies were selected, and the results were narratively summarized. A framework for information synthesis was developed which categorized results into three major themes: how gender roles and spousal dynamics function in spousal support for dietary adherence, the role of race and ethnicity in the influence of spousal support on dietary adherence, and the extant interventional work specifically targeting spousal support for T2D. The reviewed studies indicate that gender role performance is the principal factor in the relationship between spousal support and dietary adherence in T2D, though race and ethnicity also contribute. Despite this evidence, interventions that specifically target spousal support to improve dietary adherence in T2D have had limited efficacy. A better understanding of the relationship between spousal support and dietary adherence, as well as a subsequent utilization of this information to create targeted and effective interventions, would be of great benefit to the field of diabetes management.

Optimizing a Positive Psychology Intervention to Promote Health Behaviors After an Acute Coronary Syndrome: The Positive Emotions After Acute Coronary Events III (PEACE-III) Randomized Factorial Trial.

OBJECTIVE: Despite the clear benefits of physical activity and related behaviors on prognosis, most patients experiencing an acute coronary syndrome (ACS) remain nonadherent to these behaviors. Deficits in positive psychological constructs (e.g., optimism) are linked to reduced participation in health behaviors, supporting the potential utility of a positive psychology (PP)-based intervention in post-ACS patients. Accordingly, we aimed to identify optimal components of a PP-based intervention to promote post-ACS physical activity. METHODS: As part of a multiphase optimization strategy, we completed a randomized factorial trial with eight conditions in 128 post-ACS patients to efficiently identify best-performing intervention components. All participants received a PP-based intervention, with conditions varying in duration (presence/absence of booster sessions), intensity (weekly/daily PP exercises), and content (PP alone or combined with motivational interviewing), allowing three concurrent comparisons within the trial. The study aims included assessments of the overall feasibility, acceptability, and impact of the intervention, along with the primary aim of determining which components were associated with objectively measured physical activity and self-reported health behavior adherence at 16 weeks, assessed using longitudinal models. RESULTS: The intervention was well accepted and associated with substantial improvements in behavioral and psychological outcomes. Booster sessions were associated with greater activity to a nearly significant degree (ß = 8.58, 95% confidence interval = -0.49-17.65, effect size difference = .43, p = .064), motivational interviewing was associated with overall adherence (ß = 0.95, 95% confidence interval = 0.02-1.87, effect size difference = .39, p = .044), and weekly exercise completion was generally superior to daily. CONCLUSIONS: These findings will enable optimization of the PP-based intervention in preparation for a well-powered controlled trial. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov, NCT02754895.

Cluster randomized controlled trial of a multilevel physical activity intervention for older adults.

BACKGROUND: Older adults are the least active population group. Interventions in residential settings may support a multi-level approach to behavior change. METHODS: In a cluster randomized control trial, 11 San Diego retirement communities were assigned to a physical activity (PA) intervention or a healthy aging attention control condition. Participants were 307 adults over 65 years old. The multilevel PA intervention was delivered with the assistance of peer leaders, who were trained older adult from the retirement communities. Intervention components included individual counseling & self-monitoring with pedometers, group education sessions, group walks, community advocacy and pedestrian community change projects. Intervention condition by time interactions were tested using generalized mixed effects regressions. The primary outcomes was accelerometer measured physical activity. Secondary outcomes were blood pressure and objectively measured physical functioning. RESULTS: Over 70% of the sample were 80 years or older. PA significantly increased in the intervention condition (56 min of moderate-vigorous PA per week; 119 min of light PA) compared with the control condition and remained significantly higher across the 12 month study. Men and participants under 84 years old benefited most from the intervention. There was a significant decrease in systolic (p < .007) and diastolic (p < .02) blood pressure at 6 months. Physical functioning improved but the changes were not statistically significant. CONCLUSIONS: Intervention fidelity was high demonstrating feasibility. Changes in PA and blood pressure achieved were comparable to other studies with much younger participants. Men, in particular, avoided a year-long decline in PA.

Magnitude and sources of distress in mid-life adults with chronic medical illness: an exploratory mixed-methods analysis.

Most mid-life adults have at least one chronic medical condition (CMC) and are at risk for developing additional CMCs. Stressors specific to this life stage may contribute to CMC development by hindering healthy behaviors. The goal of this study was to compare sources and intensity of distress, as they relate to health behaviors, between mid-life and non-mid-life adults with CMCs. We utilized a mixed-methods approach by analyzing quantitative self-report measures of psychiatric symptoms and psychological well-being, with in-depth, semi-structured qualitative interviews to identify sources of stress in three cohorts of patients with CMCs (heart failure, type 2 diabetes, and coronary artery disease). Between-group differences on self-report measures were compared via independent samples t-tests and relevant themes from interview transcripts were compared via chi-square analysis. We found that mid-life participants (n = 30) reported greater psychological distress (depression/anxiety) than non-mid-life (n = 62) participants (Hospital Anxiety and Depression Scale scores 13.8 [SD 7.3] vs. 10.6 [SD 6.6]; t(90)=2.13; p = .035), and qualitative analysis revealed several specific sources of stress significantly more common (p < .001) in mid-life adults. Interventions targeting the needs of this population could reduce distress, improve health behaviors, and have a major impact on public health.

The Positive Emotions after Acute Coronary Events behavioral health intervention: Design, rationale, and preliminary feasibility of a factorial design study.

BACKGROUND: Positive psychological constructs, such as optimism, are associated with greater participation in cardiac health behaviors and improved cardiac outcomes. Positive psychology interventions, which target psychological well-being, may represent a promising approach to improving health behaviors in high-risk cardiac patients. However, no study has assessed whether a positive psychology intervention can promote physical activity following an acute coronary syndrome. OBJECTIVE: In this article we will describe the methods of a novel factorial design study to aid the development of a positive psychology-based intervention for acute coronary syndrome patients and aim to provide preliminary feasibility data on study implementation. METHODS: The Positive Emotions after Acute Coronary Events III study is an optimization study (planned N = 128), subsumed within a larger multiphase optimization strategy iterative treatment development project. The goal of Positive Emotions after Acute Coronary Events III is to identify the ideal components of a positive psychology-based intervention to improve post-acute coronary syndrome physical activity. Using a 2 × 2 × 2 factorial design, Positive Emotions after Acute Coronary Events III aims to: (1) evaluate the relative merits of using positive psychology exercises alone or combined with motivational interviewing, (2) assess whether weekly or daily positive psychology exercise completion is optimal, and (3) determine the utility of booster sessions. The study's primary outcome measure is moderate-to-vigorous physical activity at 16 weeks, measured via accelerometer. Secondary outcome measures include psychological, functional, and adherence-related behavioral outcomes, along with metrics of feasibility and acceptability. For the primary study outcome, we will use a mixed-effects model with a random intercept (to account for repeated measures) to assess the main effects of each component (inclusion of motivational interviewing in the exercises, duration of the intervention, and inclusion of booster sessions) from a full factorial model controlling for baseline activity. Similar analyses will be performed on self-report measures and objectively-measured medication adherence over 16 weeks. We hypothesize that the combined positive psychology and motivational interviewing intervention, weekly exercises, and booster sessions will be associated with superior physical activity. RESULTS: Thus far, 78 participants have enrolled, with 72% of all possible exercises fully completed by participants. CONCLUSION: The Positive Emotions after Acute Coronary Events III study will help to determine the optimal content, intensity, and duration of a positive psychology intervention in post-acute coronary syndrome patients prior to testing in a randomized trial. This study is novel in its use of a factorial design within the multiphase optimization strategy framework to optimize a behavioral intervention and the use of a positive psychology intervention to promote physical activity in high-risk cardiac patients.

Development of measures to evaluate youth advocacy for obesity prevention.

BACKGROUND: Youth advocacy has been successfully used in substance use prevention but is a novel strategy in obesity prevention. As a precondition for building an evidence base for youth advocacy for obesity prevention, the present study aimed to develop and evaluate measures of youth advocacy mediator, process, and outcome variables. METHODS: The Youth Engagement and Action for Health (YEAH!) program (San Diego County, CA) engaged youth and adult group leaders in advocacy for school and neighborhood improvements to nutrition and physical activity environments. Based on a model of youth advocacy, scales were developed to assess mediators, intervention processes, and proximal outcomes of youth advocacy for obesity prevention. Youth (baseline n = 136) and adult group leaders (baseline n = 47) completed surveys before and after advocacy projects. With baseline data, we created youth advocacy and adult leadership subscales using confirmatory factor analysis (CFA) and described their psychometric properties. RESULTS: Youth came from 21 groups, were ages 9-22, and most were female. Most youth were non-White, and the largest ethnic group was Hispanic/Latino (35.6%). The proposed factor structure held for most (14/20 youth and 1/2 adult) subscales. Modifications were necessary for 6 of the originally proposed 20 youth and 1 of the 2 adult multi-item subscales, which involved splitting larger subscales into two components and dropping low-performing items. CONCLUSIONS: Internally consistent scales to assess mediators, intervention processes, and proximal outcomes of youth advocacy for obesity prevention were developed. The resulting scales can be used in future studies to evaluate youth advocacy programs.

A Positive Psychology Intervention for Patients with an Acute Coronary Syndrome: Treatment Development and Proof-of-Concept Trial.

Positive psychological constructs are associated with superior outcomes in cardiac patients, but there has been minimal study of positive psychology (PP) interventions in this population. Our objective was to describe the intervention development and pilot testing of an 8-week phone-based PP intervention for patients following an acute coronary syndrome (ACS). Initial intervention development and single-arm proof-of-concept trial, plus comparison of the PP intervention to a subsequently-recruited treatment as usual (TAU) cohort. PP development utilized existing literature, expert input, and qualitative interview data in ACS patients. In the proof-of-concept trial, the primary outcomes were feasibility and acceptability, measured by rates of exercise completion and participant ratings of exercise ease/utility. Secondary outcomes were pre-post changes in psychological outcomes and TAU comparisons, measured using effect sizes (Cohen's d). The PP intervention and treatment manual were successfully created. In the proof-of-concept trial, 17/23 PP participants (74 %) completed at least 5 of 8 exercises. Participants rated the ease (M = 7.4/10; SD = 2.1) and utility (M = 8.1/10, SD = 1.6) of PP exercises highly. There were moderate pre-post improvements (ds = .46-.69) in positive affect, anxiety, and depression, but minimal effects on dispositional optimism (d = .08). Compared to TAU participants (n = 22), PP participants demonstrated greater improvements in positive affect, anxiety, and depression (ds = . 47-.71), but not optimism. A PP intervention was feasible, well-accepted, and associated with improvements in most psychological measures among cardiac patients. These results provide support for a larger trial focusing on behavioral outcomes.

Association between anxiety and mortality in patients with coronary artery disease: A meta-analysis.

BACKGROUND: Depression and anxiety are common in patients with coronary artery disease (CAD). Although depression clearly has been associated with mortality in this population, the relationship between anxiety and mortality is less clear. Accordingly, we performed a series of meta-analyses to (1) examine the relationship between anxiety and mortality in patients with established CAD and (2) determine if this relationship differs in patients with stable CAD compared to those who have just had an acute coronary syndrome (ACS). METHODS AND RESULTS: Systematic literature searches identified 44 articles (total N = 30,527) evaluating the prospective relationship between anxiety and mortality in individuals with established CAD. A series of 8 adjusted and unadjusted meta-analyses were performed to examine this relationship across all patients, with sensitivity analyses completed in post-ACS and stable CAD cohorts. In unadjusted analyses, anxiety was associated with a moderate increase in mortality risk (odds ratio 1.21 per SD increase in anxiety). However, when adjusting for covariates, nearly all associations became nonsignificant. In sensitivity analyses, anxiety was associated with an increased risk of poor outcomes in the stable CAD-but not post-ACS-cohort. CONCLUSIONS: These analyses confirm that anxiety is associated with increased risk of mortality in patients with CAD; however, this relationship is not as strong as that of depression and may be explained partly by other clinical factors. If anxiety screening is performed, it should be performed during a period of clinical stability and should target anxiety disorders rather than anxiety symptoms alone.

Is Your Neighborhood Designed to Support Physical Activity? A Brief Streetscape Audit Tool.

INTRODUCTION: Macro level built environment factors (eg, street connectivity, walkability) are correlated with physical activity. Less studied but more modifiable microscale elements of the environment (eg, crosswalks) may also affect physical activity, but short audit measures of microscale elements are needed to promote wider use. This study evaluated the relation of a 15-item neighborhood environment audit tool with a full version of the tool to assess neighborhood design on physical activity in 4 age groups. METHODS: From the 120-item Microscale Audit of Pedestrian Streetscapes (MAPS) measure of street design, sidewalks, and street crossings, we developed the 15-item version (MAPS-Mini) on the basis of associations with physical activity and attribute modifiability. As a sample of a likely walking route, MAPS-Mini was conducted on a 0.25-mile route from participant residences toward the nearest nonresidential destination for children (n = 758), adolescents (n = 897), younger adults (n = 1,655), and older adults (n = 367). Active transportation and leisure physical activity were measured with age-appropriate surveys, and accelerometers provided objective physical activity measures. Mixed-model regressions were conducted for each MAPS item and a total environment score, adjusted for demographics, participant clustering, and macrolevel walkability. RESULTS: Total scores of MAPS-Mini and the 120-item MAPS correlated at r = .85. Total microscale environment scores were significantly related to active transportation in all age groups. Items related to active transport in 3 age groups were presence of sidewalks, curb cuts, street lights, benches, and buffer between street and sidewalk. The total score was related to leisure physical activity and accelerometer measures only in children. CONCLUSION: The MAPS-Mini environment measure is short enough to be practical for use by community groups and planning agencies and is a valid substitute for the full version that is 8 times longer.

Is the relationship between the built environment and physical activity moderated by perceptions of crime and safety?

BACKGROUND: Direct relationships between safety concerns and physical activity have been inconsistently patterned in the literature. To tease out these relationships, crime, pedestrian, and traffic safety were examined as moderators of built environment associations with physical activity. METHODS: Exploratory analyses used two cross-sectional studies of 2068 adults ages 20-65 and 718 seniors ages 66+ with similar designs and measures. The studies were conducted in the Baltimore, Maryland-Washington, DC and Seattle-King County, Washington regions during 2001-2005 (adults) and 2005-2008 (seniors). Participants were recruited from areas selected to sample high- and low- income and walkability. Independent variables perceived crime, traffic, and pedestrian safety were measured using scales from validated instruments. A GIS-based walkability index was calculated for a street-network buffer around each participant's home address. Outcomes were total physical activity measured using accelerometers and transportation and leisure walking measured with validated self-reports (IPAQ-long). Mixed effects regression models were conducted separately for each sample. RESULTS: Of 36 interactions evaluated across both studies, only 5 were significant (p< .05). Significant interactions did not consistently support a pattern of highest physical activity when safety was rated high and environments were favorable. There was not consistent evidence that safety concerns reduced the beneficial effects of favorable environments on physical activity. Only pedestrian safety showed evidence of a consistent main effect with physical activity outcomes, possibly because pedestrian safety items (e.g., crosswalks, sidewalks) were not as subjective as those on the crime and traffic safety scales. CONCLUSIONS: Clear relationships between crime, pedestrian, and traffic safety with physical activity levels remain elusive. The development of more precise safety variables and the use of neighborhood-specific physical activity outcomes may help to elucidate these relationships.
