Reliability and Validity of Diabetes Nutrition Self-Efficacy and Behavior Measures for the "What Can I Eat" Diabetes Nutrition Education Program for American Indian and Alaska Native Adults With Type 2 Diabetes.

BACKGROUND: American Indian and Alaska Native (AI/AN) people have high rates of diabetes and limited access to nutrition education. The "What Can I Eat? Healthy Choices for People With Type 2 Diabetes" (WCIE) diabetes nutrition education program was culturally adapted for AI/AN adults. OBJECTIVE: This analysis was designed to evaluate the reliability and validity of items developed to measure diabetes nutrition self-efficacy (ie, confidence one can engage in specific behaviors) and diabetes nutrition behavior among participants in the WCIE program for AI/AN adults. DESIGN: This study was a secondary analysis of data from a randomized controlled trial designed to evaluate the WCIE program for AI/AN adults. Baseline data were used to assess the reliability and validity of the self-efficacy and behavior items, which were collected via survey. Due to COVID-19 safety protocols, the intervention was conducted via Zoom (Zoom Video Communications), and both survey and clinical data were collected at home by participants. PARTICIPANTS/SETTING: The study was conducted from January to December 2021 with 5 AI/AN-serving health care programs in Oklahoma, Illinois, North Carolina, California, and New York. AI/AN adults with type 2 diabetes who spoke English and had internet access were eligible. Sixty people participated. MAIN OUTCOME MEASURES: Analyses examined validity and reliability of diabetes nutrition self-efficacy and behavior items. STATISTICAL ANALYSIS PERFORMED: To test reliability, internal consistency and factor structures of the scales were examined. To evaluate convergent validity, Pearson correlations were computed to examine the association of the self-efficacy and behavior measures with each other and with clinical indicators (ie, body mass index, blood pressure, and hemoglobin A1c). RESULTS: Two self-efficacy factors were identified. Each showed strong internal consistency (Cronbach α ≥ 0.85; McDonald ω ≥ 0.88) and was directly associated with diabetes nutrition behavior (P < .001). The factor assessing Confidence in Using the Diabetes Plate was inversely associated with hemoglobin A1c (Pearson correlation = -0.32, P = .0243). The behavior measure capturing Healthy Nutrition Behavior showed strong internal consistency (α = 0.89; ω = 0.92) and was inversely associated with hemoglobin A1c (Pearson correlation = -0.38, P = .0057). CONCLUSIONS: Diabetes nutrition self-efficacy and behavior items developed for the WCIE program for AI/AN adults are valid and reliable. These items can facilitate rigorous and consistent evaluation of the AI/AN WCIE program.

Evaluation of a Synchronous, Online Diabetes Nutrition Education Program for American Indians and Alaska Natives With Type 2 Diabetes: Facilitators and Participants' Experiences.

OBJECTIVE: To explore the overall experiences of key players involved in a culturally adapted, online, synchronous diabetes nutrition education program across 5 reservation tribal and intertribal urban Indian clinics. METHODS: A multimethods design, including postclass surveys with Likert-scale and short-answer questions, was completed after each of the 5 classes. Participants (n = 54) and class facilitators/coordinators (n = 10) completed postclass surveys (n = 189 and 58, respectively). A subset of participants (n = 24) and all class facilitators/coordinators (n = 10) engaged in online focus groups after the conclusion of program implementation. Qualitative thematic methods and frequency distributions were used to analyze the data. RESULTS: Most participants reported that the classes were enjoyable (94%), culturally respectful (77%), and easily accessed online (68%). Qualitative themes included (1) class satisfaction, (2) class improvements, (3) preference for class facilitator, and (4) recommendations to improve recruitment and retention. CONCLUSIONS AND IMPLICATIONS: These findings will guide program modifications to provide improved diabetes nutrition education for American Indians and Alaska Natives adults with type 2 diabetes.

An online diabetes nutrition education programme for American Indian and Alaska Native adults with type 2 diabetes: perspectives from key stakeholders.

OBJECTIVE: To explore stakeholder perspectives regarding online diabetes nutrition education for American Indians and Alaska Natives (AI/AN) with type 2 diabetes (T2D). DESIGN: Qualitative data were collected through focus groups and interviews. Focus group participants completed a brief demographic and internet use survey. SETTING: Focus groups and community participant interviews were conducted in diverse AI/AN communities. Interviews with nationally recognised content experts were held via teleconference. PARTICIPANTS: Eight focus groups were conducted with AI/AN adults with T2D (n 29) and their family members (n 22). Community participant interviews were conducted with eleven clinicians and healthcare administrators working in Native communities. Interviews with nine content experts included clinicians and researchers serving AI/AN. RESULTS: Qualitative content analysis used constant comparative method for coding and generating themes across transcripts. Descriptive statistics were computed from surveys. AI/AN adults access the internet primarily through smartphones, use the internet for many purposes and identify opportunities for online diabetes nutrition education. CONCLUSIONS: Online diabetes nutrition education may be feasible in Indian Country. These findings will inform the development of an eLearning diabetes nutrition education programme for AI/AN adults with T2D.

Health literacy and knowledge of chronic transfusion therapy in adolescents with sickle cell disease and caregivers.

BACKGROUND: Patients with sickle cell disease (SCD) may require chronic transfusion therapy (CTT) for prevention of stroke or other complications. Limited health literacy (HL) is common and is associated with poor health-related knowledge and outcomes in chronic disease. We sought to assess HL and transfusion knowledge in patients with SCD on CTT and their caregivers. METHODS: A cross-sectional study of patients was conducted in outpatient hematology clinics. Forty-five pairs of adolescent patients and caregivers and 20 caregivers of pre-adolescent patients completed the Newest Vital Sign HL assessment and answered questions assessing SCD and transfusion knowledge. Community-level median income and unemployment rates were estimated from Census data. We computed the correlation of HL with knowledge and compared each to Census variables, payor status, educational attainment, and stroke. RESULTS: HL was inadequate in 22 (34%) caregivers and 31 (69%) adolescents. Adequate caregiver HL was associated with higher educational attainment but not community-level socioeconomics or payor status. Mean knowledge score was lower in adolescents than in caregivers and correlated with age in adolescents (r = 0.42, P = .004). HL correlated with knowledge (r = 0.46, P < .0001). There were no significant correlations of HL or knowledge between adolescents and their caregivers. Neither HL nor knowledge was associated with prior stroke. The greatest knowledge was demonstrated for iron overload and SCD genotype, whereas knowledge gaps existed in alloimmunization, indication for CTT, and SCD curative therapy. CONCLUSIONS: Enhanced educational resources in transfusion therapy, alloimmunization, and curative therapy are needed for patients with SCD and caregivers of all HL levels.

Improving the Effectiveness of Medication Review: Guidance from the Health Literacy Universal Precautions Toolkit.

BACKGROUND: Although routine medication reviews in primary care practice are recommended to identify drug therapy problems, it is often difficult to get patients to bring all their medications to office visits. The objective of this study was to determine whether the medication review tool in the Agency for Healthcare Research and Quality Health Literacy Universal Precautions Toolkit can help to improve medication reviews in primary care practices. METHODS: The toolkit's "Brown Bag Medication Review" was implemented in a rural private practice in Missouri and an urban teaching practice in California. Practices recorded outcomes of medication reviews with 45 patients before toolkit implementation and then changed their medication review processes based on guidance in the toolkit. Six months later we conducted interviews with practice staff to identify changes made as a result of implementing the tool, and practices recorded outcomes of medication reviews with 41 additional patients. Data analyses compared differences in whether all medications were brought to visits, the number of medications reviewed, drug therapy problems identified, and changes in medication regimens before and after implementation. RESULTS: Interviews revealed that practices made the changes recommended in the toolkit to encourage patients to bring medications to office visits. Evaluation before and after implementation revealed a 3-fold increase in the percentage of patients who brought all their prescription medications and a 6-fold increase in the number of prescription medications brought to office visits. The percentage of reviews in which drug therapy problems were identified doubled, as did the percentage of medication regimens revised. CONCLUSIONS: Use of the Health Literacy Universal Precautions Toolkit can help to identify drug therapy problems.

Update on health literacy and diabetes.

PURPOSE: Inadequate literacy is common among patients with diabetes and may lead to adverse outcomes. The authors reviewed the relationship between literacy and health outcomes in patients with diabetes and potential interventions to improve outcomes. METHODS: We reviewed 79 articles covering 3 key domains: (1) evaluation of screening tools to identify inadequate literacy and numeracy, (2) the relationships of a range of diabetes-related health outcomes with literacy and numeracy, and (3) interventions to reduce literacy-related differences in health outcomes. RESULTS: Several screening tools are available to assess patients' print literacy and numeracy skills, some specifically addressing diabetes. Literacy and numeracy are consistently associated with diabetes-related knowledge. Some studies suggest literacy and numeracy are associated with intermediate outcomes, including self-efficacy, communication, and self-care (including adherence), but the relationship between literacy and glycemic control is mixed. Few studies have assessed more distal health outcomes, including diabetes-related complications, health care utilization, safety, or quality of life, but available studies suggest low literacy may be associated with increased risk of complications, including hypoglycemia. Several interventions appear to be effective in improving diabetes-related outcomes regardless of literacy status, but it is unclear if these interventions can reduce literacy-related differences in outcomes. CONCLUSIONS: Low literacy is associated with less diabetes-related knowledge and may be related to other important health outcomes. Further studies are needed to better elucidate pathways by which literacy skills affect health outcomes. Promising interventions are available to improve diabetes outcomes for patients with low literacy; more research is needed to determine their effectiveness outside of research settings.

The impact of executive cognitive functioning on rates of smoking cessation in the San Luis Valley Health and Aging Study.

Cigarette smoking is one of the leading preventable causes of death. Previous research has shown that many common smoking cessation interventions are effective with older smokers; a few interventions have been tailored to this population. To our knowledge, however, no smoking cessation research or interventions targeted at older adults have addressed the influence of cognition on successful smoking cessation. We hypothesized that impairment of executive cognitive functioning (ECF), which is relatively prevalent among older adults, would negatively influence smoking cessation rates among older smokers. The relationship of ECF to smoking cessation was examined in a population-based sample of 1,338 community-dwelling older persons in Colorado's San Luis Valley, 204 of whom were current smokers. As predicted, current ECF did not predict early smoking behaviour, but was a significant predictor of successful smoking cessation. Older persons suffering from executive dysfunction were less likely to have quit smoking than were their cognitively intact counterparts (OR = 1.10, 95% CI 1.04-1.17, P < 0.01). Among those with normal ECF, 73.7% had quit smoking, compared with 65.1% of participants showing any level of ECF impairment. Limiting the sample to individuals who were active smokers at or after the age of 65, when executive impairment is relatively common, produced similar results. Individuals with better executive functioning were more likely to have quit smoking (OR = 1.12, 95% CI 1.02-1.23, P = 0.02).
