BackgroundThe objectives of this study were to characterize survivorship models of care across eight LIVESTRONG Survivorship Center of Excellence (COE) Network sites and to identify barriers and facilitators influencing survivorship care.MethodsUsing the framework of the Chronic Care Model (CCM), quantitative and qualitative methods of inquiry were conducted with the COEs. Methods included document reviews, key informant telephone interviews with 39 participants, online Assessment of Chronic Illness Care (ACIC) surveys with 40 participants, and three site visits.ResultsSeveral overarching themes emerged in qualitative interviews and were substantiated by quantitative methods. Health system factors supporting survivorship care include organization and leadership commitment and program champions at various levels of the health care team. System barriers include reimbursement issues, lack of space, and the need for leadership commitment to support changes in clinical practices as well as having program “champions” among clinical staff. Multiple models of care include separate survivorship clinics and integrated models as well as consultative models. COEs’ scores on the ACIC survey showed overall “reasonable support” for survivorship care; however, the clinical information system domain was least developed. Although the ACIC findings indicated “reasonable support” for self-management, the qualitative analysis revealed that self-management support was largely limited to health promotion provided in clinic-based education and counseling sessions, with few COEs providing patients with self-management tools and interventions.ConclusionsThe CCM framework captured experiences and challenges of these COEs and provided insight into the current state of survivorship care in the context of National Cancer Institute-designated comprehensive cancer centers. Findings showed that cancer patients and providers could benefit from clinical information systems that would better identify candidates for survivorship care and provide timely information. In addition, a crucial area for development is self-management support outside of clinical care.Implications for cancer survivorsCancer survivors may benefit from learning about the experience and challenges faced by the eight LIVESTRONG Centers of Excellence in developing programs and models for cancer survivorship care, and these findings may inform patient and caregiver efforts to seek, evaluate, and advocate for quality survivorship programs designed to meet their needs.

OBJECTIVE To evaluate whether the evidence-based Body & Soul program, when disseminated and implemented without researcher or agency involvement and support, would achieve results similar to those of earlier efficacy and effectiveness trials. DESIGN Prospective group randomized trial. SETTING Churches with predominantly African American membership. PARTICIPANTS A total of 1,033 members from the 15 churches completed baseline surveys. Of these participants, 562 (54.4%) completed the follow-up survey 6 months later. INTERVENTION Church-based nutrition program for African Americans that included pastoral involvement, educational activities, church environmental changes, and peer counseling. MAIN OUTCOME MEASURE Daily fruit and vegetable (FV) intake was assessed at pre- and posttest. ANALYSIS Mixed-effects linear models. RESULTS At posttest, there was no statistically significant difference in daily servings of FVs between the early intervention group participants compared to control group participants (4.7 vs 4.4, P = .38). Process evaluation suggested that added resources such as technical assistance could improve program implementation. CONCLUSIONS AND IMPLICATIONS The disseminated program may not produce improvements in FV intake equal to those in the earlier efficacy and effectiveness trials, primarily because of a lack of program implementation. Program dissemination may not achieve public health impact unless support systems are strengthened for adequate implementation at the church level.

OBJECTIVE Body & Soul, an evidence-based nutrition program for African Americans churches, is currently being disseminated nationally and free of charge by the National Cancer Institute. For dissemination feasibility, the peer counseling training is done via DVD rather than by live trainers. We describe implementation and process evaluation of the peer counseling component under real world conditions. METHODS The study sample included 11 churches (6 early intervention, 5 delayed intervention) in 6 states. Data sources included training observations, post-training debriefing sessions, coordinator interviews, and church participant surveys. Survey data analysis examined associations between exposure to peer counseling and change in dietary intake. Qualitative data were analyzed using the constant comparative method. RESULTS Eight of 11 churches initiated the peer counseling program. Recall of talking with a peer counselor was associated with significantly (p<.02) greater fruit and vegetable intake. Data indicate sub-optimal program execution after peer counselor training. CONCLUSION Inconsistent implementation of the peer counseling intervention is likely to dilute program effectiveness in changing nutrition behaviors. PRACTICE IMPLICATIONS Disseminating evidence-based programs may require added resources, training, quality control, and technical assistance for improving program uptake. Similar to earlier research phases, systematic efforts at the dissemination phase are needed for program success.

PURPOSE This study examined the effects of a physical activity (PA) intervention for young adult cancer survivors on changes in self-efficacy, social support, and self-monitoring and determined whether changes in these social cognitive theory constructs mediated the relationship between the intervention and changes in PA. METHODS A 12-week randomized trial compared a Facebook-based intervention (FITNET) aimed at increasing moderate-to-vigorous intensity PA to a Facebook-based self-help comparison group. Young adult cancer survivors (N=86, aged 21-39) were randomly assigned to one of the two groups. Self-report measures of PA and psychosocial variables were collected at baseline and after 12 weeks. RESULTS The FITNET group reported lower self-efficacy for sticking to exercise (mean change=-0.38; 95% CI: -0.62 to -0.12; p=0.025) and social support from friends on social networking websites (mean change=-0.47; 95% CI: -1.45 to 0.65; p=0.039) relative to the self-help comparison group over time. Changes in social support from friends on social networking websites partially mediated the intervention effects on moderate-to-vigorous PA (mean indirect effect=-22.4; 95% CI: -62.0 to -2.8) in the unexpected direction. Across both groups, social support from friends and self-monitoring were positively associated with changes in moderate-to-vigorous PA. CONCLUSION The proposed mediators did not explain the positive effects of the FITNET intervention on mild PA. The lack of significant improvements in psychosocial constructs among FITNET participants may partly explain why the intervention did not increase moderate-to-vigorous PA relative to the self-help comparison group. Future PA interventions with young adult cancer survivors should examine targeting social support from friends and self-monitoring.

High-tech tools for exercise motivation: use and role of technologies such as the internet, mobile applications, social media, and video games.

Deborah F. Tate; Elizabeth J. Lyons; Carmina G. Valle

IN BRIEF The majority of patients with type 2 diabetes are not active at recommended levels, and many do not have access to behavior change programs to support lifestyle change. Thus, tools and programs designed to promote the adoption and maintenance of physical activity using technology may be helpful. This article reviews the evidence regarding the use of technology tools such as the Internet, mobile applications, social media, and video games and provides suggestions for evaluating the potential benefit of such tools for behavior change.

BACKGROUND Obesity is a significant problem among US veterans. Diets high in fruits and vegetables (FV) can lower obesity risk. Health communication interventions are promising strategies for promoting healthy eating. We evaluated whether an enhanced intervention with tailored newsletters and motivational interviewing calls would be more effective than the Veterans Affairs (VA) weight management program, MOVE!, at increasing FV intake among overweight/obese veterans. METHODS Using a quasi-experimental design, 195 veterans at two clinics participated at baseline and 6-month follow-up from 2005 to 2006. Measures included daily FV intake and information processing of the intervention. The control group (MOVE!) received educational information, group sessions, and standard phone calls about weight. The intervention included MOVE! components plus tailored newsletters and motivational interviewing calls. RESULTS The intervention group reported a statistically significant increase in FV servings compared to control (1.7 vs. 1.2; p ≤ 0.05). Veterans who read more of the tailored newsletters (β=0.15, p=0.01) and perceived the messages as important (β=0.12, p<0.01) and applicable to their lives (β=0.12, p<0.01) ate more FV than those who did not. However, receiving MI calls and information processing regarding the calls were not associated with FV intake. CONCLUSION A tailored intervention can impact short term FV intake for obesity prevention.

A diet high in fruits and vegetables (F&Vs) is associated with decreased risk for cardiovascular disease, diabetes, and cancer. This study investigated the relationship between sociodemographic, health, and psychosocial factors and F&V consumption among overweight and obese U.S. veterans. Participants were recruited from two Veterans Affairs medical center sites in 2005. Two hundred eighty-nine participants completed a self-administered survey. Bivariate and multivariate linear regression models were built to examine the association between sociodemographic, health, and psychosocial variables and F&V consumption. Older age (B = 0.01; p < 0.001) and being Black (B = -0.18; p < 0.05) were related to increased F&V consumption. Reported tobacco use was inversely associated with F&V consumption (B = -0.30; p < 0.01). Greater self-efficacy (B = 0.07; p < 0.05), fewer perceived barriers (B = -0.14; p < 0.01), and correct knowledge of recommended daily F&V intake (B = 0.12; p <0.05) were related to eating more F&Vs. U.S. veterans disproportionately experience overweight and obese conditions. Age, race, tobacco use, and psychosocial factors should be considered carefully when developing dietary interventionsamong overweight ana obese U.S. veterans.

Friend and Family Support for Weight Loss in Adolescent Females.

Noel Kulik; Carmina G. Valle; Deborah F. Tate

BACKGROUND Overweight and obesity rates in children and adolescents are concerning, particularly among girls. Social support from friends has been associated with healthier eating and higher levels of physical activity, yet little is known about the relationship between social support and weight loss among adolescents. This aim of this study was to prospectively examine the relationship between baseline social support from friends and family, changes in social support, and weight loss. METHODS Sixty-five adolescent girls completed a one-year weight loss intervention trial. Data were collected at baseline, 6 months, and 12 months. RESULTS At baseline, family support was higher compared to friend support; however, lower friend support at baseline and increases in friend support from baseline to 6 months and 12 months were associated with weight loss. When controlling for other predictors of weight loss, change in friend support for healthy eating was predictive of weight loss at 12 months. CONCLUSIONS These findings suggest that weight loss interventions for adolescent females might consider including strategies to elicit or to create and promote social support for healthy eating from peers. Future studies are needed to test this relationship.

Physical Activity in Young Adults: A Signal Detection Analysis of Health Information National Trends Survey (HINTS) 2007 Data

Carmina G. Valle; Deborah F. Tate; Deborah K. Mayer; Marlyn Allicock; Jianwen Cai; Marci K. Campbell

Many young adults are insufficiently active to achieve the health benefits of regular physical activity. Using signal detection analysis of data from the 2007 Health Information National Trends Survey, the authors examined distinct subgroups of 18–39 year-old adults who vary in their likelihood of not meeting physical activity recommendations. We randomly split the sample and conducted signal detection analysis on the exploratory half to identify subgroups and interactions among sociodemographic and health communication variables that predicted engaging in less than 150 minutes per week of moderate-intensity physical activity (low physical activity). We compared rates of low physical activity among subgroups with similarly defined subgroups in the validation sample. Overall, 62% of participants did not meet physical activity recommendations. Among 8 subgroups identified, low physical activity rates ranged from 31% to 90%. Predictors of low physical activity were general health, body mass index (BMI), perceived cancer risk, health-related Internet use, and trust in information sources. The least active subgroup (90% low physical activity) included young adults in poor to good health with a BMI of 30.8 or more (obese). The most active subgroup (31% low physical activity) comprised those in very good to excellent health, who used a website to help with diet, weight, or physical activity, and had little to no trust in health information on television. Findings suggest potential intervention communication channels and can inform targeted physical activity interventions for young adults.
