Examining cultural adaptations of the savvy caregiver program for Korean American caregivers using the framework for reporting adaptations and modifications-enhanced (FRAME).

BACKGROUND: The Framework for Reporting Adaptations and Modifications-Enhanced (FRAME) is a tool that systematically guides decision-making and reporting of adaptations made to evidence-based interventions. Using FRAME, we documented the process and outcomes of adapting the Savvy Caregiver Program (SCP) for Korean American dementia caregivers. METHODS: Sequential adaptation was initiated with linguistic attunement, followed by pilot implementation and full adaptation. Our data-driven adaptation with multiple data sources and a feedback loop among multiple stakeholders yielded a total of 32 modifications, and each was coded according to the eight domains of FRAME: (1) what was modified, (2) who participated in recommending and deciding the modification to be made, (3) when the modification occurred, (4) whether the modification was planned, (5) whether the modification was fidelity-consistent, (6) whether the modification was temporary, (7) at what level of delivery, the modification was made, and (8) why the modification was made. RESULTS: The areas of adaptation were evenly distributed across context (37.5%), content (31.2%), and training (31.2%). The primary reasons for modification were for engagement (62.5%), followed by fit with recipients (43.8%) and outcome improvement (31.1%). About 66% of the modifications were applied to the entire target group, and all modifications were fidelity-consistent. CONCLUSIONS: The FRAME categorization provided a detailed understanding of the process and nature of adapting the SCP and served as a foundation for further implementation and scale-up. FRAME not only serves as a guide for adapting evidence-based interventions but also promotes their replicability and scalability.

Health Literacy and Outcomes of a Community-Based Self-Help Intervention: A Case of Korean Americans With Type 2 Diabetes.

BACKGROUND: Although scientific reports increasingly document the negative impact of inadequate health literacy on health-seeking behaviors, health literacy's effect on health outcomes in patients with diabetes is not entirely clear, owing to insufficient empirical studies, mixed findings, and insufficient longitudinal research. OBJECTIVE: The aim of this study was to empirically examine underlying mechanisms of health literacy's role in diabetes management among a group of Korean Americans with Type 2 diabetes mellitus. METHODS: Data from a randomized clinical trial of a health literacy-focused Type 2 diabetes self-management intervention conducted during 2012-2016 in the Korean American community were collected at baseline and at 3, 6, 9, and 12 months. A total of 250 Korean Americans with Type 2 diabetes participated (intervention, 120; control, 130). Participants were first-generation Korean American immigrants. Health literacy knowledge was measured with the original Rapid Estimate of Adult Literacy in Medicine and the diabetes mellitus-specific Rapid Estimate of Adult Literacy in Medicine. Functional health literacy was measured with the numeracy subscale of the Test of Functional Health Literacy in Adults and the Newest Vital Sign screening instrument, which also uses numeracy. Primary outcomes included glucose control and diabetes quality of life. Multivariate analyses included latent variable modeling. RESULTS: A series of path analyses identified self-efficacy and self-care skills as significant mediators between health literacy and glucose control and quality of life. Education and acculturation were the most significant correlates of health literacy. DISCUSSION: Despite inconsistent findings in the literature, this study indicates that health literacy may indirectly influence health outcomes through mediators such as self-care skills and self-efficacy. The study highlights the importance of health literacy, as well as underlying mechanisms with which health literacy influences processes and outcomes of diabetes self-management.

Community Health Workers Versus Nurses as Counselors or Case Managers in a Self-Help Diabetes Management Program.

OBJECTIVES: To confirm the effectiveness of community health workers' involvement as counselors or case managers in a self-help diabetes management program in 2009 to 2014. METHODS: Our open-label, randomized controlled trial determined the effectiveness of a self-help intervention among Korean Americans aged 35 to 80 years in the Baltimore-Washington metropolitan area with uncontrolled type 2 diabetes. We measured and analyzed physiological and psychobehavioral health outcomes of the community health worker-counseled (n = 54) and registered nurse (RN)-counseled (n = 51) intervention groups in comparison with the control group (n = 104). RESULTS: The community health workers' performance was comparable to that of the RNs for both psychobehavioral outcomes (e.g., self-efficacy, quality of life) and physiological outcomes. The community health worker-counseled group showed hemoglobin A1C reductions from baseline (-1.2%, -1.5%, -1.3%, and -1.6%, at months 3, 6, 9, and 12, respectively), all of which were greater than reductions in the RN-counseled (-0.7%, -0.9%, -0.9%, and -1.0%) or the control (-0.5%, -0.5%, -0.6%, and -0.7%) groups. CONCLUSIONS: Community health workers performed as well as or better than nurses as counselors or case managers in a self-help diabetes management program in a Korean American community.

Effect of childhood obesity prevention programs on blood pressure: a systematic review and meta-analysis.

BACKGROUND: Childhood overweight and obesity are associated with elevated blood pressure (BP). However, little is known about how childhood obesity lifestyle prevention programs affect BP. We assessed the effects of childhood obesity prevention programs on BP in children in developed countries. METHODS AND RESULTS: We searched databases up to April 22, 2013, for relevant randomized, controlled trials, quasi-experimental studies, and natural experiments. Studies were included if they applied a diet or physical activity intervention(s) and were followed for ≥ 1 year (or ≥ 6 months for school-based intervention studies); they were excluded if they targeted only overweight/obese subjects or those with a medical condition. In our meta-analysis, intervention effects were calculated for systolic BP and diastolic BP with the use of weighted random-effects models. Of the 23 included intervention studies (involving 18 925 participants), 21 involved a school setting. Our meta-analysis included 19 studies reporting on systolic BP and 18 on diastolic BP. The pooled intervention effect was -1.64 mm Hg (95% confidence interval, -2.56 to -0.71; P=0.001) for systolic BP and -1.44 mm Hg (95% confidence interval, -2.28 to -0.60; P=0.001) for diastolic BP. The combined diet and physical activity interventions led to a significantly greater reduction in both systolic BP and diastolic BP than the diet-only or physical activity-only intervention. Thirteen interventions (46%) had a similar effect on both adiposity-related outcomes and BP, whereas 11 interventions (39%) showed a significant desirable effect on BP but not on adiposity-related outcomes. CONCLUSIONS: Obesity prevention programs have a moderate effect on reducing BP, and those targeting both diet and physical activity seem to be more effective.

Translation and validation of the dietary approaches to stop hypertension for koreans intervention: culturally tailored dietary guidelines for Korean Americans with high blood pressure.

BACKGROUND: Lifestyle modification strategies such as adoption of the Dietary Approaches to Stop Hypertension (DASH) diet are now recognized as an integral part of high blood pressure (HBP) management. Although the high prevalence of HBP among Korean Americans (KAs) is well documented, few dietary interventions have been implemented in this population, in part because of a lack of culturally relevant nutrition education guidelines. Translating and testing the efficacy of culturally relevant dietary recommendations using a well-established dietary guideline such as DASH are imperative for promoting better cardiovascular health for this high-risk cultural group. OBJECTIVE: The aims of this study were to systematically translate and validate a culturally modified DASH for Koreans (K-DASH) and obtain preliminary evidence of efficacy. METHODS: A 2-step approach of intervention translation and efficacy testing, together with close adherence to principles of community-based participatory research, was used to maximize community input. A 1-group pre-post design with 24-hour urine and 24-hour ambulatory blood pressure monitoring comparisons was used to test the initial feasibility and efficacy of the K-DASH intervention. RESULTS: A total of 28 KAs with HBP participated in a 10-week dietary intervention consisting of group education sessions and individual counseling. Both systolic blood pressure and diastolic blood pressure, as measured by ambulatory blood pressure monitoring, were significantly decreased at postintervention evaluation (systolic blood pressure, -4.5 mm Hg; diastolic blood pressure, -2.6 mm Hg; P < .05). Serum low-density lipoprotein cholesterol was significantly decreased (-7.3 mg/dL; P < .05). Serum potassium and ascorbic acid levels were also improved in the reference range. Urine potassium level was significantly increased, supporting increased fruit and vegetable consumption. CONCLUSION: This pilot study has (a) demonstrated that a cultural adaptation of DASH using community-based participatory research methodology produced a culturally relevant and efficacious dietary intervention for the KAs with HBP and (b) provided strong preliminary evidence for the efficacy of the K-DASH intervention in reducing HBP in hypertensive KAs.

COVID-19 health information sources and their associations with preventive behaviors: A typological study with older residents in Seoul, South Korea.

Considering that individuals' health information can enable their adoption of health behaviors, we examined the use of health information sources related to COVID-19 and its association with preventive behaviors in a sample of older residents in Seoul, South Korea (N = 400, M age = 76.1 years). Latent profile analysis of 12 sources of health information representing conventional media, online sources, interpersonal networks, and health professionals or authorities yielded a 4-group typology: limited, moderate/traditional, moderate/digital, and diverse. In a multivariate model with the diverse group as a reference, the limited group (B = -4.48, SE = 1.14, p < .001) and the moderate/digital group (B = -2.73, SE = 0.76, p < .001) were associated with lower adherence to COVID-19 preventive behaviors. Our findings support the heterogeneity in the use of health information sources and the hypothesis that groups with restricted sources of health information would report less desirable behaviors. The findings also underscored the importance of proper use of digital health information. Efforts should be made not only to help older adults with low education access diverse sources of health information, including digital sources, but also to empower them to build digital and health literacy.

Lessons Learned from Rapid Community Needs Assessment in the African American Community During the COVID-19 Pandemic.

BACKGROUND: With the accelerated spread of COVID-19 and current shelter-in-place orders from many local governments, African American (AA) communities see to be more vulnerable as emerging data show disproportionate rates of infection and mortality among AAs across the nation. OBJECTIVES: In a sample of AA church members, to conduct a rapid community assessment during the early phase of the coronavirus disease 2019 pandemic. METHODS: Our community-based participatory research team, partnering with the local AA church community and including trained lay health workers, conducted the assessment via telephone and online. RESULTS: Although most participants reported high confidence regarding recommendations for physical distancing, more than 60% reported elevated anxiety and stress, and 10% indicated that they needed more information about staying healthy and safe during the pandemic. CONCLUSIONS: Community-based participatory research with lay health workers is an effective method to implement a community needs assessment, problem-solve with community members, and build community health infrastructure during a public health crisis.

A meta-analysis of interventions to promote mammography among ethnic minority women.

BACKGROUND: Although many studies have been focused on interventions designed to promote mammography screening among ethnic minority women, few summaries of the effectiveness of the interventions are available. OBJECTIVE: The aim of this study was to determine the effectiveness of the interventions for improving mammography screening among asymptomatic ethnic minority women. METHODS: A meta-analysis was performed on intervention studies designed to promote mammography use in samples of ethnic minority women. Random-effects estimates were calculated for interventions by measuring differences in intervention and control group screening rates postintervention. RESULTS: The overall mean weighted effect size for the 23 studies was 0.078 (Z = 4.414, p < .001), indicating that the interventions were effective in improving mammography use among ethnic minority women. For mammography intervention types, access-enhancing strategies had the biggest mean weighted effect size of 0.155 (Z = 4.488, p < .001), followed by 0.099 (Z = 6.552, p < .001) for individually directed approaches such as individual counseling or education. Tailored, theory-based interventions resulted in a bigger effect size compared with nontailored interventions (effect sizes = 0.101 vs. 0.076, respectively; p < .05 for all models). Of cultural strategies, ethnically matched intervention deliveries and offering culturally matched intervention materials had effect sizes of 0.067 (Z = 2.516, p = .012) and 0.051 (Z = 2.365, p = .018), respectively. DISCUSSION: Uniform improvement in mammography screening is a goal to address breast cancer disparities in ethnic minority communities in this country. The results of this meta-analysis suggest a need for increased use of a theory-based, tailored approach with enhancement of access.

The Effect of a Community-Based Self-Help Intervention: Korean Americans With Type 2 Diabetes.

INTRODUCTION: Korean Americans are one of the most underserved ethnic/linguistic minority groups owing to cultural and institutional barriers; there is an urgent need for culturally competent diabetes management programs in the Korean American community for those with type 2 diabetes. The purpose of this study was to test the effectiveness of a community-based, culturally tailored, multimodal behavioral intervention program in an ethnic/linguistic minority group with type 2 diabetes. DESIGN: An RCT with waitlist comparison based on the Predisposing, Reinforcing, and Enabling Constructs in Education/environmental Diagnosis and Evaluation (PRECEDE)-Policy, Regulatory, and Organizational Constructs in Educational and Environmental Development (PROCEED) and self-help models. Data were collected between September 2010 and June 2013 and were analyzed in August-December 2014. Statistical significance was set at p<0.05. SETTING/PARTICIPANTS: In a naturally occurring community setting, a total of 250 Korean Americans with type 2 diabetes were randomized into an intervention group (n=120) or a control group (n=130). INTERVENTION: The intervention consisted of key self-management skill-building activities through 12 hours of group education sessions, followed by integrated counseling and behavioral coaching by a team of RNs and community health workers. MAIN OUTCOME MEASURES: Primary (clinical) outcomes were hemoglobin A1c, glucose, total cholesterol, and low-density lipoprotein at baseline and at 3, 6, 9, and 12 months. Secondary (psychosocial and behavioral) outcomes included diabetes-related quality of life, self-efficacy, adherence to diabetes management regimen, and health literacy. RESULTS: During the 12-month project, the intervention group demonstrated 1.0%-1.3% (10.9-14.2 mmol/mol) reductions in hemoglobin A1c, whereas the control group achieved reductions of 0.5%-0.7% (5.5-7.7 mmol/mol). The differences between the two groups were statistically significant. The intervention group showed statistically significant improvement in diabetes-related self-efficacy and quality of life when compared with the control group. CONCLUSIONS: RN/community health worker teams equipped with culturally tailored training can be effective in helping an ethnic/linguistic minority group manage diabetes in the community.

An introduction to item response theory for patient-reported outcome measurement.

The growing emphasis on patient-centered care has accelerated the demand for high-quality data from patient-reported outcome (PRO) measures. Traditionally, the development and validation of these measures has been guided by classical test theory. However, item response theory (IRT), an alternate measurement framework, offers promise for addressing practical measurement problems found in health-related research that have been difficult to solve through classical methods. This paper introduces foundational concepts in IRT, as well as commonly used models and their assumptions. Existing data on a combined sample (n = 636) of Korean American and Vietnamese American adults who responded to the High Blood Pressure Health Literacy Scale and the Patient Health Questionnaire-9 are used to exemplify typical applications of IRT. These examples illustrate how IRT can be used to improve the development, refinement, and evaluation of PRO measures. Greater use of methods based on this framework can increase the accuracy and efficiency with which PROs are measured.

Factors related to risk of cardiovascular disease among older korean chinese with hypertension.

PURPOSE: The purpose of this study was to assess the prevalence of cardiovascular disease (CVD) risk factors among older Korean Chinese with hypertension-one of the most underserved and understudied ethnic minority groups in China. In addition, factors underlying the risk of CVD were examined. METHODS: A total of 334 participants were recruited at the Community Health Service Center in Yanji, China. Data regarding socioeconomic, health-related, psychosocial, and other CVD risk factors were collected between June and October 2009. In this cross-sectional study, factors related to the risk of CVD were assessed by multivariate logistic regression; the Framingham Risk Score was used to measure the risk of CVD. RESULTS: The prevalence of dyslipidemia, diabetes, and current smoking were 75.4%, 6.6%, and 23.1% respectively. Participants who lived alone were twice as likely to have a high risk of CVD (10-year risk of CVD ≥15%; odds ratio [OR], 2.00; 95% confidence interval [CI], 1.13-3.54). Those with a higher education level and greater knowledge about hypertension were at 57% and 62% reduced risk for CVD (OR, 0.43; 95% CI, 0.21-0.92 and OR, 0.38; 95% CI, 0.15-0.95, respectively). CONCLUSION: Future intervention should include strategies to addressing social isolation and also focus on older Korean Chinese with low education. Knowledge enhancement program is warranted for the prevention of CVD in this population.

Implementation and success of nurse telephone counseling in linguistically isolated Korean American patients with high blood pressure.

OBJECTIVE: Nurse telephone counseling can improve the management of chronic conditions, but the effectiveness of this approach in underserved populations is unclear. This study evaluated the use of bilingual nurse-delivered telephone counseling in Korean Americans (KAs) participating in a community-based intervention trial to improve management of hypertension. METHODS: KAs were randomized to receive 12 months of hypertension-related telephone counseling that was more intensive (bi-weekly) or less intensive (monthly). Counseling logs were kept for 360 KAs who completed the pre- and post-intervention evaluations. RESULTS: The overall success rate for the intervention was 80.3%. The level of success was significantly influenced by the dose of counseling, employment status, and years of US residence. Over the 12-month counseling period, both groups showed improvement with regard to medication-taking, alcohol consumption, and exercise but not smoking, with no significant group differences. CONCLUSION: Bilingual telephone counseling could reach monolingual KAs and improve their hypertension management behavior. PRACTICE IMPLICATIONS: Bilingual nurse telephone counseling may have wide applicability, serving as an effective means of disseminating evidence-based chronic disease management guidelines to a linguistically isolated community with limited health resources and information.

Effects of a theory-driven music and movement program for stroke survivors in a community setting.

Many countries lack effective community-based rehabilitation programs despite the increasing numbers of stroke survivors. Therefore, we have conducted a pilot investigation in South Korea of a newly constructed community-based intervention program combining rhythmic music and specialized rehabilitation movement. The 8-week program was based on rhythmic auditory stimulation (RAS) theory, which uses rhythm to enhance stroke survivors' movements. Thirty-three stroke survivors were randomized into one of two groups: The experimental group (n = 16) carried out an 8-week RAS music-movement exercise intervention; the control group (n = 17) received referral information about available usual care services. Participants in the experimental group gained a wider range of motion and flexibility, had more positive moods, and reported increased frequency and quality of interpersonal relationships.

Knowledge, beliefs, and behaviors about hypertension control among middle-aged Korean Americans with hypertension.

This report describes the management and control of high blood pressure (HBP) in a sample of middle-aged (40 to 64 years) Korean Americans (KAs) with HBP. Participants in the Self-Help Intervention Program for HBP care (SHIP-HBP), a culturally tailored clinical trial for HBP management in KAs through lifestyle approaches, underwent baseline assessments to determine HBP control status and knowledge, beliefs, and practices related to HPB control. Data were stratified by sex. In all, 445 Korean patients are described. About 55% of the sample were receiving antihypertensive therapy, and less than one-third had controlled BP (< 140/90 mm Hg). Sex differences were observed in terms of clinical characteristics and anti-hypertensive medication use: women were more likely than men to have controlled BP and lower diastolic BP and to have been on HBP medication. Lower rates of smoking, drinking, and overweight or obesity were also observed more frequently in women. Most participants agreed that taking anti-hypertensive medication lowered BP. When asked what the most important behavioral factor was for controlling BP, about a quarter reported cutting down on salt, followed by exercise and medication taking. While poor HBP control remains a common problem that contributes to significant cardiovascular morbidity and mortality, particularly among ethnic minorities, our findings underscore the need to test the beneficial effects of primary and secondary prevention programs, suitably modified to meet the language, cultural, and individual needs of this high-risk population of hypertensive patients.
