"I did not want to take that medicine": African-Americans' reasons for diabetes medication nonadherence and perceived solutions for enhancing adherence

Best fit framework synthesis of qualitative studies on factors associated with medication nonadherence in people with type 2 diabetes using the COM-B model

This review aimed to synthesize factors associated with medication nonadherence among people with type 2 diabetes (PwT2D), using the Capability, Opportunity, Motivation and Behaviour (COM-B) model as the a priori model. Studies published between January 2014 and April 2024 were searched on five databases. Studies were included if they recruited PwT2D aged >18 years, investigated factors associated with adherence to oral and/or nonoral medications for diabetes, used qualitative research methods, were conducted in a community setting, were in English language and had accessible full-text articles. Best fit framework synthesis was undertaken, which led to the development of a hypothesized COM-B variant model specific to medication nonadherence among PwT2D. Study quality was assessed using published criteria to evaluate whether the study was adequately reported. Twenty-two studies were included. Factors were mapped onto the COM-B model: physical capability (e.g., difficulty injecting insulin independently), psychological capability (e.g., understanding about diabetes), physical opportunity (e.g., cost of medication), social opportunity (e.g., quality of communication and relationship with healthcare providers), automatic motivation (e.g., habit formation) and reflective motivation (e.g., perceived necessity and effectiveness of medications). Reflective motivation had the most themes, while physical capability only had one theme. Personality was a theme that could not be mapped onto the model. Interactions between some COM-B components (e.g., capability and motivation) were observed. This theoretically grounded synthesis may facilitate future intervention development by formulating a programme theory and identifying behaviour change techniques to address the identified factors.

Perspectives of medication-related experiences in Black persons with kidney diseases: The patient voice

PURPOSE

Black persons comprise 13.4% of the US population but represent 36% of those with kidney failure. Medication-related disparities likely contribute to these outcomes. Patient perspective provides valuable insight into what they need and want from their medications and their care.

METHODS

We conducted five 1.25-hour online focus group sessions via a videoconferencing app between March 30 and June 27, 2022. Our nationally recruited sample consisted of 19 adults 37 to 72 years of age who represented a broad range of educational backgrounds, all with CKD (non-dialysis-dependent, dialysis-dependent, or post kidney transplant). Semistructured guides were constructed by our team and used by moderators. Inductive thematic analysis procedures were followed. Patients representative of our study population were integral members of our research team.

RESULTS

Our analysis includes 3 major themes and associated subthemes: (1) meet patients where they are (subthemes: patient autonomy and empowerment, experience with illness, home and community support, barriers to understanding, and barriers to access; (2) the patient journey with medications (subthemes: fears with medications, frustrations and burdens with medication use, adjusting to medications, desire for awareness and explanation, preferences with medications, and helpful tools and supports; and (3) significant interactions with healthcare professionals (subthemes: barriers to building trust, type of care and interactions desired, and care team communication).

CONCLUSION

Recognizing the patient as an individual, addressing their frustrations and needs with medications, and attending to implicit biases and strategies to overcome barriers and empower Black persons with CKD are anticipated to reduce medication- related disparities and improve health outcomes experienced by this population.

A pilot mixed methods randomized control trial investigating the feasibility and acceptability of a culturally tailored intervention focused on beliefs, mistrust and race-congruent peer support for Black adults with diabetes

Introduction

Black adults disproportionately experience poor glycemic control and medication nonadherence, yet few diabetes self-management programs address their unique health beliefs, provider mistrust and sociocultural barriers to taking diabetes medications. This 6-month pilot randomized feasibility trial compared a culturally tailored diabetes self-management program, incorporating beliefs about diabetes, mistrust, and race-congruent peer support to a standard diabetes program.

Methods

An embedded mixed methods design examined the feasibility of the pilot trial, including recruitment, retention, intervention adherence and participant acceptability. Data were collected through participant self-reported questionnaires, field notes, semi-structured interviews, and focus groups. Qualitative content analysis inductively explored participants' feedback on the program, participation barriers and potential strategies to overcome the challenges. Mixed methods integration was implemented using a side-by-side joint display to compare, synthesize and interconnect the quantitative and qualitative results across all feasibility domains.

Results

Thirteen participants (93%) completed the trial, demonstrating high adherence and retention. Community outreach and a prerequisite orientation using motivational interviewing were feasible and appropriate to recruit potential participants. Participants expressed high satisfaction and acceptability, highlighting the importance of peer support, cultural relevant content and a safe space for sharing experiences. Barriers to participation were identified including schedule conflicts and difficulties in engagement.

Discussion

Future large-scale effectiveness trials should consider combining multimedia into recruitment methods, tailoring the program to address medication-taking goals, and addressing social and environmental barriers to support sustained lifestyle changes.

Optimizing diabetes management interventions for Black and Hispanic adults using the multiphase optimization strategy: Protocol for a randomized mixed methods factorial trial

BACKGROUND

Black and Hispanic adults with diabetes are more likely to experience diabetes complications and die from diabetes compared to non-Hispanic whites. This disparity may be due to medication adherence being negatively affected by social determinants of health (SDOH) and negative beliefs about diabetes and diabetes medicines. Pharmacist delivered medication therapy management (MTM) improves clinical outcomes. However, pharmacists have limited capacity and expertise to address SDOH barriers and health misperceptions. Supplementing MTM with Community Health Workers (CHWs) to address these factors may be more effective with potential for implementation.

AIM

To investigate what combination of two possible components, pharmacist delivered MTM and CHWs addressing SDOH barriers and health misperceptions, represents the optimized intervention for Black and Hispanic adults with uncontrolled diabetes.

METHODS/DESIGN

We will use a 2 × 2 factorial design (MTM, CHW: ON vs. OFF) where participants will be randomized to one of four treatment conditions in a 6-month intervention delivered mostly by phone. We will recruit 376 Black or Hispanic adults with type 2 diabetes and hemoglobin A1C of ≥8 %, a clinical indicator of uncontrolled type 2 diabetes. The primary outcome is A1C measured at 6 months, and at 12 months for sustained change. The secondary outcome is medication adherence. Several psychosocial factors will be examined as potential mediators. An embedded experimental mixed methods approach will be used to obtain participant perspectives through qualitative interviews and integrated to assess intervention acceptability.

DISCUSSION

Our findings will identify the optimized intervention, e.g., comprising MTM or CHW or both intervention components, that effectively and efficiently improves diabetes outcomes among Black and Hispanic adults with uncontrolled diabetes, informing dissemination.

A network analysis to explore illness perceptions in Black adults with type 2 diabetes

OBJECTIVES

This study explores the structure of beliefs about type 2 diabetes among Black adults and informs potential targets to reframe negative beliefs and enhance diabetes self-management.

RESEARCH DESIGN AND METHODS

We applied network analysis to investigate the interrelated structure and clusters of beliefs about diabetes and identify specific items that could serve as behavioural targets. We obtained self-reported survey data from 170 Black adults with type 2 diabetes. Regularised partial correlation networks and a Gaussian graphical model were used to explore and visualise the interrelationship among 21 items of a culturally adapted Illness Perception Questionnaire-Revised.

RESULTS

Overwhelming negative emotions representing the current and long-term effects of diabetes were central to the illness perceptions network among Black adults, with feeling depressed having the highest node strength of centrality indices in the network. Four beliefs had a bridging effect with the central cluster: diabetes taking away the ability to enjoy food, diabetes keeping me away from the job I want, being poor contributed to my having diabetes, and I receive encouragement from friends and family.

CONCLUSIONS

In addition to highlighting the overwhelming feeling of diabetes, the illness perception network further differentiated the role of racial identity and social determinants of health as discrete, though both are related sociocultural influence constructs. To enhance self-management for Black adults with type 2 diabetes, this network informs promising intervention targets focused on culturally tailored education related to emotional regulation, internalised stigma and healthy food adaptation, and leveraging support to address social determinants of health.

"We Don't Get Drugs Targeted for Us:" Applying the Integrated Behavioral Model to Understand Why Black Women Chose to Participate in a Breast Cancer Clinical Trial

Guided by the integrated behavioral model, the authors interviewed 14 Black breast cancer survivors (N = 14) who had participated in a breast cancer clinical trial. This study aimed to better understand what may motivate Black women to engage in medical research and decide to participate in medical research. Findings revealed that Black women's altruistic desires to serve others and their communities are greatly influenced by the need to leave a "legacy" of better treatment for other Black women. The participants mostly learned about clinical trials through communicating with friends, family, or other breast cancer patients and survivors, rather than from their physicians. Many were influenced to participate by other Black breast cancer patients they knew, suggesting that social norms messaging may help alert other Black women about the continuing disparity in clinical trial participation. Finally, the participants in this study demonstrated high levels of involvement not only in seeking out clinical trials, but also in engaging in informed and shared decision-making with their providers about participating in the trials. The findings from this work illuminate important reasons Black women chose to participate in breast cancer clinical trials. Additionally, we offer robust and valuable theoretical and practical implications for researchers, so they can work toward successfully increasing Black women's participation in clinical trials.

Racial and ethnic disparities in treatment refusal for head and neck cutaneous malignancies

Racial and ethnic minorities with skin cancer experience disproportionately worse prognoses and adverse outcomes compared to non-Hispanic, White patients. We analyzed patients diagnosed with any cutaneous malignancies of the head and neck between 2010 to 2021 using the data from the National Cancer Database to quantify disparities. The primary outcome variable was treatment refusal, and secondary variables included days from diagnosis to treatment, tumor depth, and mortality. Among the 151,733 patients analyzed, most were non-Hispanic White (99%) and male (71%). Black patients had the greatest odds of treatment refusal (4.166, 95% CI: 2.054-8.452, p < 0.001) across all cutaneous malignancies of the head and neck. Black and Hispanic patients also had increased times from diagnosis to treatment (p < 0.001). Black patients had higher odds of 90-day mortality compared to non-Hispanic White patients (p < 0.001). This coincided with greater tumor depth in Black and Hispanic patients compared to that of non-Hispanic White patients (p < 0.001). Black patients were more likely to refuse treatment for head and neck cutaneous malignancies. Moreover, Black and Hispanic patients experienced more treatment delays. These findings may relate to the increased 90-day mortality among Black patients and increased tumor depth in Black and Hispanic patients. Further investigation into the quality of life and functional impairment is warranted alongside interventions to reduce these disparities.

Prevalence, reasons and factors associated with intentional nonadherence to prescribed medications: a population-based study

OBJECTIVE

To evaluate the frequency, reasons and factors associated with intentional nonadherence to drug therapy.

METHODS

A population-based cross-sectional study was conducted with data from the National Survey on Access, Use and Promotion of Rational Use of Medicines (PNAUM). The questionnaire consisted of sociodemographic questions, presence of chronic diseases, medication use, self-rated health, and medication use behaviors. Data analysis included Poisson regression models adjusted for variance.

RESULTS

A total of 31,573 individuals were included, most of whom were women (53.8%), with low level of education (57.7%), and self-rated good health (56.5%). Of those interviewed, 8.8% reported increasing the medication dose and 21.2% reported reducing it. The most common reason for dose reduction was the adverse effects of the medication. There were no differences in the reasons for increasing doses. Increasing or reducing doses were most commonly reported by younger people, with lower per capita income and worse self-rated health.

CONCLUSION

A considerable portion of the respondents did not intentionally adhere to drug therapy. Understanding nonadherence and identifying those who practice it is crucial for creating effective strategies that promote adherence to treatment and prioritize patients' needs and perspectives.

Understanding the influence of ethnicity on adherence to antidiabetic medication: Meta-ethnography and systematic review

INTRODUCTION

A high prevalence of diabetes and diabetes-related complications in people from minority ethnic communities in high income countries is of significant concern. Several studies have indicated low adherence rates to antidiabetic medication in ethnic minority groups. Poor adherence to antidiabetic medication leads to a higher risk of complications and potential mortality. This review aims to qualitatively explore the barriers to and facilitators of adherence to antidiabetic medication among ethnic minority groups in high-income countries.

METHODS

A comprehensive search of MEDLINE, Embase, CINAHL, PsycINFO, and Global Health databases for qualitative studies exploring the barriers to or facilitators of adherence to antidiabetic medication in minority ethnic groups was conducted from database inception to March 2023 (PROSPERO CRD42022320681). A quality assessment of the included studies was conducted using the Critical Appraisal Skills Programme (CASP) tool. Key concepts and themes from relevant studies were synthesised using a meta-ethnographic approach. The Grading of Recommendations Assessment, Development and Evaluation Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) approach was used to assess the Confidence in the review findings.

RESULT

Of 13,994 citations screened, 21 studies that included primary qualitative studies were selected, each of which involved people from minority ethnic communities from eight high income countries. This qualitative evidence synthesis has identified three overarching themes around the barriers to and facilitators of adherence to antidiabetic medication among ethnic minority groups.: 1) cultural underpinnings, 2) communication and building relationships, and 3) managing diabetes during visiting home countries. Based on the GRADE-CERQual assessment, we had mainly moderate- and high-confidence findings.

CONCLUSION

Multiple barriers and facilitators of adherence to antidiabetic medication among people from minority ethnic communities in high-income countries have been identified. A medication adherence intervention focusing on identified barriers to adherence to antidiabetic medication in these communities may help in improving diabetes outcomes in these groups.

Trends and Race/Ethnic Disparities in Diabetes-Related Hospital Use in Medicaid Enrollees: Analyses of Serial Cross-sectional State Data, 2008-2017

BACKGROUND

Race/ethnic disparities in preventable diabetes-specific hospital care may exist among adults with diabetes who have Medicaid coverage.

OBJECTIVE

To examine race/ethnic disparities in utilization of preventable hospital care by adult Medicaid enrollees with diabetes across nine states over time.

DESIGN

Using serial cross-sectional state discharge records for emergency department (ED) visits and inpatient (IP) hospitalizations from the Healthcare Cost and Utilization Project, we quantified race/ethnicity-specific, state-year preventable diabetes-specific hospital utilization.

PARTICIPANTS

Non-Hispanic Black, non-Hispanic White, and Hispanic adult Medicaid enrollees aged 18-64 with a diabetes diagnosis (excluding gestational or secondary diabetes) who were discharged from hospital care in Arizona, Iowa, Kentucky, Florida, Maryland, New Jersey, New York, North Carolina, and Utah for the years 2008, 2011, 2014, and 2017.

MAIN MEASURES

Non-Hispanic Black-over-White and Hispanic-over-White rate ratios constructed using age- standardized state-year, race/ethnicity-specific ED, and IP diabetes-specific utilization rates.

KEY RESULTS

The ratio of Black-over-White ED utilization rates for preventable diabetes-specific hospital care increased across the 9 states in our sample from 1.4 (CI 95, 1.31-1.50) in 2008 to 1.73 (CI 95, 1.68-1.78) in 2017. The cross-year-state average non-Hispanic Black-over-White IP rate ratio was 1.46 (CI 95, 1.42-1.50), reflecting increases in some states and decreases in others. The across-state-year average Hispanic-over-White rate ratio for ED utilization was 0.67 (CI 95, 0.63-0.71). The across-state-year average Hispanic-over-White IP hospitalization rate ratio was 0.72 (CI 95, 0.69-0.75).

CONCLUSIONS

Hospital utilization by non-Hispanic Black Medicaid enrollees with diabetes was consistently greater and often increased relative to utilization by White enrollees within state programs between 2008 and 2017. Hispanic enrollee hospital utilization was either lower or indistinguishable relative to White enrollee hospital utilization in most states, but Hispanic utilization increased faster than White utilization in some states. Among broader patterns, there is heterogeneity in the magnitude of race/ethnic disparities in hospital utilization trends across states.

Methodological - Theoretical approach to phenomenological studies on the experience of medication use: A systematic review

BACKGROUND

The study of medication use should include pharmacological, family, and social dimensions to explain how the lived experiences, beliefs, and perceptions of everyone, and their social and cultural environment affects consumption, using for this purpose the qualitative approach.

OBJECTIVE

To conduct a systematic review of the theoretical-methodological approaches to phenomenology to identify studies that allow an understanding of patients' experiences with the use of medications.a.

METHODS

A systematic literature search was conducted following the PRISMA guidelines to identify studies that address phenomenological research on patients' experiences of medications used and to apply them in subsequent studies. A thematic analysis was performed using ATLAS.ti software to facilitate data management.

RESULTS

Twenty-six articles were identified, most of them including adult patients diagnosed with chronic degenerative diseases. The semantic network obtained places Phenomenology at the center as the interpretative referential framework, with three theoretical approaches: descriptive, interpretative, and perceptual under the philosophies of Husserl, Heidegger, and Merleau-Ponty respectively; two techniques to collect data which are in-depth interview and focus groups; and to explore the life experiences of patients and understand the meaning in the context of their lives, thematic analysis, content analysis, and interpretative phenomenological analysis were identified.

CONCLUSIONS

It was evidenced that Qualitative Research approaches, methodologies, and techniques are applicable to describe people's experiences towards the use of medications. Phenomenology constitutes a useful referential framework in qualitative research to explain the experiences and perceptions about the disease and the use of medicines.

Ethnic disparities in medication adherence? A systematic review examining the association between ethnicity and antidiabetic medication adherence

OBJECTIVES

Adherence to prescribed medication is an essential component of diabetes management to obtain optimal outcomes. Understanding the relationship between medication adherence and ethnicity is key to optimising treatment for all people with different chronic illnesses, including those with diabetes. The aim of this review is to examine whether the adherence to antidiabetic medications differed by ethnicity among people with diabetes.

METHODS

A systematic review was conducted of studies reporting adherence to antidiabetic medication amongst people from different ethnic groups. MEDLINE, Embase, CINAHL, and PsycINFO were searched from their inception to June 2022 for quantitative studies with a specific focus on studies assessing adherence to antidiabetic medications (PROSPERO: CRD42021278392). The Joanna Briggs Institute critical appraisal checklist and a second checklist designed for studies using retrospective databases were used to assess study quality. A narrative synthesis approach was used to summarize the results based on the medication adherence measures.

RESULTS

Of 17,410 citations screened, 41 studies that included observational retrospective database research and cross-sectional studies were selected, each of which involved diverse ethnic groups from different settings. This review identified a difference in the adherence to antidiabetic medications by ethnicity in 38 studies, despite adjustment for several confounding variables that may otherwise explain these differences.

CONCLUSION

This review revealed that adherence to antidiabetic medication differed by ethnicity. Further research is needed to explore the ethnicity-related factors that may provide an explanation for these disparities.

Pain, No Gain?: A Narrative Analysis Exploring the Accounts of Older African American Patients and Their Discussion of Pain Management Related to Chronic Illness

Drawing from interviews conducted as part of a study of older African Americans with multimorbidity, we argue how various forms of racism work together to shape communication between doctors and patients. By focusing on what patients say about pain, we highlight patient descriptions of their relationships with pain management, their interactions with healthcare providers, and how they navigate understanding their chronic conditions. Our documentation of patient experience with stigmas and biases suggests what is needed for more empathetic and effective communication within the doctor and patient relationship. We conclude by using the interview data to propose addressing racial inequality in health care in the United States through educational reform and training initiatives grounded in rhetorical research.

Protocol for a Pilot Randomized Controlled Mixed Methods Feasibility Trial of a Culturally Adapted Peer Support and Self-Management Intervention for African Americans

BACKGROUND

Due to diabetes disparities commonly seen among African Americans, it is important to address psychosocial and sociocultural barriers to medication adherence among African Americans with diabetes. Building on our prior work testing a culturally adapted peer supported diabetes self-management intervention for African Americans, this study will conduct a pilot randomized controlled feasibility trial that compares the culturally adapted intervention with a standard diabetes self-management program.

METHODS

Using an intervention mixed-methods design, the six-month trial will be conducted at two sites. Twenty-four African Americans with uncontrolled type 2 diabetes will be randomized to the intervention or control arm. Feasibility and acceptability outcomes in four domains (recruitment, intervention acceptability, intervention adherence, retention) will be collected. Primary clinical outcome (A1C), secondary outcome (medication adherence) and patient-specific psychosocial measures will be collected at baseline, 2 months, and 6 months. Document review, interview and focus groups will be used to gather qualitative data on feasibility and acceptability.

RESULTS

Expected results are that the trial protocol will be feasible to implement and acceptable for participants, and there will be a signal of clinically meaningful reduction in A1C and improvements in medication adherence.

CONCLUSIONS

The results of this trial will inform a future powered large-scale randomized controlled trial testing the effectiveness of the culturally tailored intervention.

A feasibility pilot trial of a peer-support educational behavioral intervention to improve diabetes medication adherence in African Americans

BACKGROUND

African Americans are twice as likely to die from diabetes, compared to other racial and ethnic groups in the USA. Poor adherence to diabetes medications is common among African Americans and contributes to these disproportionally worse outcomes. A pilot study was conducted to determine the feasibility and acceptability of a peer-supported intervention targeting diabetes and medication beliefs, communication, and self-efficacy skills to enhance medication adherence among African Americans with type 2 diabetes.

METHODS

Based on the extended self-regulatory model and information-motivation-behavioral skills model, this intervention was piloted using a single group pre/post-intervention study design at two sites. Seventeen African Americans who self-reported as adherent to diabetes medicines (ambassadors) were paired with 22 African Americans with self-reported poor medication adherence (buddies). Feasibility outcomes evaluated recruitment, retention, and intervention adherence. Measures assessed at baseline and 1-month post-intervention included glycemic control (hemoglobin A1c), self-reported medication adherence, diabetes beliefs, concerns about diabetes medicines, and diabetes self-efficacy. Wilcoxon signed-rank tests assessed for differences in mean scores of outcome variables at baseline compared with a 3-month follow-up. Semi-structured 60-min interviews were conducted with each buddy to explore their acceptability of the intervention. To ensure the rigor of the qualitative data, we focused on analytic criteria such as credibility, confirmability, and transferability.

RESULTS

Most buddies and ambassadors were female and about 56 years old. Feasibility outcomes included recruitment success rates of 73% for buddies and 85% for ambassadors relative to our goals. Retention rate for hemoglobin A1c and medication adherence outcome assessment was 95% for buddies. Both buddies and ambassadors had excellent intervention adherence, with buddies having a mean attendance of 7.76 out of 8 sessions/phone calls and ambassadors completing > 99% of the 105 intervention calls with Buddies. Results showed a signal of change in hemoglobin A1c (effect size = 0.14) and medication adherence (effect size = 0.35) among buddies, reduction in buddies' negative beliefs about diabetes and an increase in necessity beliefs of diabetes medicines. Summative interviews with buddies showed they valued ambassador's encouragement of self-management behaviors.

CONCLUSIONS

Results support conduct of an efficacy trial to address medication adherence for African Americans with type 2 diabetes using a peer-supported tailored intervention.

A Culturally Tailored Diabetes Self-Management Intervention Incorporating Race-Congruent Peer Support to Address Beliefs, Medication Adherence and Diabetes Control in African Americans: A Pilot Feasibility Study

Introduction

Current diabetes self-management programs are often insufficient to improve outcomes for African Americans because of a limited focus on medication adherence and addressing culturally influenced beliefs about diabetes and medicines. This study evaluated the feasibility and acceptability of a novel culturally tailored diabetes self-management intervention that addressed key psychosocial and sociocultural barriers to medication adherence for African Americans.

Methods

The intervention consisted of group education and race-congruent peer-based phone support. Three African Americans who were engaged in taking their diabetes medicines (ambassadors), were matched with 8 African Americans who were not engaged in taking medicines (buddies). We conducted a single group, pre/post study design with African Americans with type 2 diabetes. Wilcoxon signed rank tests assessed mean score differences in outcomes at baseline compared with 6-months follow-up. Semi-structured interviews explored buddies' acceptability of the intervention.

Results

Buddies and ambassadors were similar in age and mostly female. Recruitment rates were 80% for buddies and 100% for ambassadors. Retention rate for primary outcomes was 75%. Buddies had a mean completion of 13.4/17 of sessions and phone calls. Ambassadors completed 84% of intervention calls with buddies. Although there were no statistically significant differences in mean A1C and medication adherence, we found a clinically meaningful decrease (-0.7) in mean A1C at the 6-month follow up compared to baseline. Secondary outcomes showed signal of changes. Themes showed buddies perceived an improvement in provider communication, learned goal setting strategies, and developed motivation, and confidence for self-management. Buddies perceived the program as acceptable and culturally appropriate.

Conclusion

This culturally tailored diabetes self-management intervention that addresses diabetes self-management, psychosocial and behavioral barriers to medication adherence, and incorporates race-congruent peer support from African Americans engaged in taking medicines seemed feasible and acceptable. The results provide support for a fully powered randomized trial to test the intervention's efficacy.

Perspectives on a Novel Culturally Tailored Diabetes Self-Management Program for African Americans: A Qualitative Study of Healthcare Professionals and Organizational Leaders

BACKGROUND

There is an urgent need for culturally tailored diabetes self-management education to improve health outcomes in African Americans, especially given the disproportionate prevalence of diabetes and medication non-adherence. Stakeholder engagement can guide and enrich the development of these interventions by integrating content directly addressing barriers to African Americans' adherence with existing community-based diabetes self-management education programs. The aim of this study is to explore stakeholder perspectives on a novel culturally tailored diabetes self-management program for African Americans.

METHODS

Thirteen semi-structured individual interviews were conducted in a large Midwestern U.S. city with healthcare professionals and organizational leaders serving African American communities and/or providing diabetes education. Transcripts were analyzed using directed content analysis with the Consolidated Framework for Implementation Research and inductive content analysis.

RESULTS

Five overarching themes were identified: (1) fulfill needs among stakeholders, (2) creating a supportive and trusting environment to address distrust, (3) building relationships and empowering peers, (4) logistical organization barriers to program implementation and (5) challenges to program acceptance by participants.

CONCLUSION

Stakeholders delineated how the new culturally tailored diabetes self-management program aligned with the needs of African American patients. Perceived challenges and corresponding strategies to address barriers to participation were identified to inform program implementation and sustainability.

Barriers and Facilitators in Access to Diabetes, Hypertension, and Dyslipidemia Medicines: A Scoping Review

Objective: Identify barriers and facilitators in access to medicines for diabetes, hypertension, and dyslipidemia, considering patient, health provider, and health system perspectives. Methods: Scoping review based on Joanna Briggs methodology. The search considered PubMed, Cochrane Library, CINAHL, Academic Search Ultimate, Web of Science, SciELO Citation Index, and grey literature. Two researchers conducted screening and eligibility phases. Data were thematically analyzed. Results: The review included 219 documents. Diabetes was the most studied condition; most of the evidence comes from patients and the United States. Affordability and availability of medicines were the most reported dimension and specific barrier respectively, both cross-cutting concerns. Among high- and middle-income countries, identified barriers were cost of medicines, accompaniment by professionals, long distances to facilities, and cultural aspects; cost of transportation emerges in low-income settings. Facilitators reported were financial accessibility, trained health workers, medicines closer to communities, and patients' education. Conclusion: Barriers and facilitators are determined by socioeconomic and cultural conditions, highlighting the role of health systems in regulatory and policy context (assuring financial coverage and free medicines); providers' role bringing medicines closer; and patients' health education and disease management.

Understanding Type 2 Diabetes Self-Management in Racial/Ethnic Minorities: Application of the Extended Parallel Processing Model and Sensemaking Theory in a Qualitative Study

PURPOSE

The purpose of the study was to understand the role of perceived disease threat and self-efficacy in type 2 diabetes (T2DM) patients' self-management by using the extended parallel processing model (EPPM) and sensemaking theory.

METHODS

Semistructured interviews (n = 25) were conducted with T2DM patients from an urban safety-net hospital. Participants were 50% male/female median age was 55 years and 76% were Black. Participants were categorized by EPPM group based on validated questionnaires (high/low disease threat [HT/LT]; high/low self-efficacy [HE/LE]). Nine were HT/HE, 7 HT/LE, 6 LT/HE, and 3 LT/LE. Interviews were transcribed and analyzed using inductive and deductive coding. Sensemaking theory was applied to contextualize and analyze data.

RESULTS

Those with HT indicated threat fluctuated throughout diagnosis but that certain triggers (eg, diabetic complications) drove changes in disease view. Those in the HT/HE group more frequently expressed disease acceptance, whereas the HT/LE group more often expressed anger or denial. HT/HE participants expressed having adequate social support and higher trust in health care providers. HT/LE participants reported limited problem-solving skills. In those with LT, the HE group took more ownership of self-management behaviors. The LT/LE group had heightened positive and negative emotional responses that appeared to limit their ability to perform self-care. They also less frequently described problem-solving skills, instead expressing reliance on medical guidance from their providers.

CONCLUSIONS

EPPM and sensemaking theory are effective frameworks for understanding how perceived health threat and self-efficacy may impede T2DM self-care. A greater focus on these constructs is needed to improve care among low-income minority patients, especially those with low threat and self-efficacy.

Racial and Ethnic Disparities in Healthcare Rating, Diabetes Self-efficacy, and Diabetes Management Among Non-pregnant Women of Childbearing Age: Does Socioeconomic Status Matter?

OBJECTIVE

Patient perceptions of healthcare ratings, diabetes self-efficacy, and diabetes management play a role in diabetes-related outcomes, particularly among women of childbearing age. Guided by a modified Interaction Model of Client Health Behavior framework, the objective was to compare differences in perceptions of health care ratings, diabetes self-efficacy, and diabetes management among non-Hispanic Black, Hispanic, and non-Hispanic White women of childbearing age.

METHODS

The sample comprised 7 years (2012-2018) of Medical Expenditure Panel Survey data. The sample was limited to women of childbearing age (18-45 years) who have ever been told they had diabetes (n = 691; weighted n = 932,426). Dependent variables were health care rating, diabetes self-efficacy, and diabetes care management. The key independent variable was race/ethnicity (non-Hispanic Black, Hispanic, non-Hispanic White). We adjusted for sociodemographic characteristics and perceived health status using multiple linear and multivariable logistic regressions.

RESULTS

Non-Hispanic Black women (41.6%) self-reported their health status as fair or poor (44.9%) compared to non-Hispanic White (33.3%) and Hispanic (37.6%). In adjusted models, non-Hispanic Black women had 46% lower odds (95% CI = 0.31, 0.94) of reporting high health care ratings compared to non-Hispanic White women. Non-Hispanic Black women had 43% lower odds (95% CI = 0.35, 0.95) and Hispanic women had 47% lower odds (95% CI = 0.34, 0.80) of reporting higher levels of diabetes care management than non-Hispanic White women.

CONCLUSIONS

This study provides important information regarding diabetes health care ratings, self-efficacy, and self-management behaviors. Because of the increasing prevalence of diabetes among women of childbearing age, it is important to improve health care particularly for racial/ethnic minority women with diabetes.

Assessment of adherence to aspirin for preeclampsia prophylaxis and reasons for nonadherence

BACKGROUND

Preeclampsia is a hypertensive disease unique to pregnancy and has a significant impact on maternal and neonatal morbidity and mortality. Daily aspirin has been demonstrated to reduce the risk of preeclampsia. The American College of Obstetricians and Gynecologists recommends daily low-dose aspirin, ideally before 16 weeks' gestation, in at-risk patients for preeclampsia risk reduction. This study examined whether patients at-risk for preeclampsia by the American College of Obstetricians and Gynecologists criteria recalled aspirin recommendation and factors associated with treatment adherence.

OBJECTIVE

This study examined whether patients at-risk for preeclampsia by the American College of Obstetricians and Gynecologists criteria recalled aspirin recommendation and factors associated with treatment adherence.

STUDY DESIGN

This study used an anonymous written survey. Pregnant patients were asked to record self-reported risk factors and to recall recommendation to take aspirin for preeclampsia prophylaxis. Participants were then determined to be high-, moderate-, or low-risk on the basis of the American College of Obstetricians and Gynecologists guidelines. Self-reported adherence to recommendations and factors contributing to the patients' decisions to take or decline aspirin were assessed. Secondary outcomes included demographic characteristics of adherent patients and patients who did not recall aspirin recommendation.

RESULTS

A total of 544 surveys were distributed and 500 were returned (91.9% response rate). Of the 104 high-risk pregnancies identified, aspirin was recommended in 60 (57.7%; 95% confidence interval, 0.48-0.67). Of the 269 patients with 2 or more moderate-risk factors, aspirin was recommended for 13 (4.8%; 95% confidence interval, 0.03-0.08). Among the participants who recalled aspirin recommendation, adherence was similar between high-risk (81.7%) and moderate-risk (76.9%) groups (P=.69). Patients with chronic hypertension, a history of preeclampsia or gestational hypertension in a previous pregnancy, and pregestational diabetes mellitus were most likely to report receiving aspirin recommendation (78.8%, 76.5%, 63.8%, and 53.3%, respectively). No high-risk factor was associated with a decreased likelihood of adherence. Nonadherent patients rarely discussed their decision with their medical provider (5.9%). In the 42.3% of high-risk participants who did not recall aspirin recommendation, autoimmune disease, multiple gestation, and kidney disease were the most prevalent risk factors (42.9%, 35.7%, and 25.0%, respectively).

CONCLUSION

In the population studied, many at-risk patients, as defined by the American College of Obstetricians and Gynecologists criteria, did not recall recommendations to take aspirin for preeclampsia prophylaxis. This raises concerns for absent or ineffective counseling. Of the patients who recalled aspirin recommendation, most reported adherence, and a history of hypertensive disorders or preeclampsia, autoimmune disease, and pregestational diabetes mellitus were most often associated with adherence. There was no single factor most strongly associated with intentional nonadherence.

Psychometric evaluation of a culturally adapted illness perception questionnaire for African Americans with type 2 diabetes

Background

Diabetes is burdensome to African Americans, who are twice as likely to be diagnosed, more likely to develop complications and are at a greater risk for death and disability than non-Hispanic whites. Medication adherence interventions are sometimes ineffective for African Americans because their unique illness perceptions are not adequately addressed. The Illness Perception Questionnaire-Revised (IPQ-R) that assesses illness perceptions has shown reliability and validity problems when used with African Americans. Thus, the study objective was to adapt the IPQ-R for African Americans and assess the validity and reliability of the culturally adapted questionnaire.

Methods

The parent study used an exploratory sequential mixed methods design, to explore African Americans’ illness perceptions qualitatively, used the results to adapt the IPQ-R, and tested the culturally adapted IPQ-R items quantitatively. In this paper, a preliminary culturally adapted IPQ-R refined based on the qualitative study, was administered to 170 middle-aged United States-based African Americans with type 2 diabetes in a face-to-face survey. Content, construct, convergent, and predictive validity, including reliability was examined. Pearson and item-total correlations, item analysis, exploratory factor analysis, multiple linear regression analysis, and test-retest were conducted.

Results

A revised culturally adapted IPQ-R was identified with a 9-factor structure and was distinct from the old factor structure of the original IPQ-R. The ‘consequences’ domain from the IPQ-R occurred as two factors (external and internal consequences) while the ‘emotional representations’ domain in the IPQ-R emerged as separate ‘present’ and ‘future’ emotional representation factors. Illness coherence’ was differently conceptualized as ‘illness interpretations’ to capture additional culturally adapted items within this domain. Most items had factor loadings greater than 0.4, with moderate factor score correlations. Necessity and concern beliefs in medicines significantly correlated with domains of the culturally adapted IPQ-R. Pearson’s correlation values were not greater than 0.7, indicating good convergent validity. The culturally adapted IPQ-R significantly predicted medication adherence. None of the correlation values were higher than 0.7 for the test-retest, indicating moderate reliability. Most domains of the culturally adapted IPQ-R had Cronbach’s alpha values higher than 0.7, indicating good internal consistency.

Conclusions

The results provide preliminary support for the validity of the culturally adapted IPQ-R in African Americans with diabetes, showing good construct, convergent and predictive validity, as well as reliability.

Relation between diabetes related distress and glycemic control: The mediating effect of adherence to treatment

AIMS

Diabetes related distress (DRD) is a negative emotional reaction to stresses associated with diabetes mellitus (DM) and its management. This study estimated the burden of DRD and self-reported adherence to treatment (SRAT) among patients with DM and investigated their relationship with glycemic control.

METHODS

A cross sectional study of consented 157 diabetics was conducted using the17-item Diabetes Distress Scale (DDS). It measures distress at four subscales: Emotional Burden (EB), Physician-related (PD), Regimen-related (RD) and Interpersonal Distress (ID). SRAT was assessed using Morisky's scale. Glycemic control was assessed using the most recent HbA1c results. Multivariable linear regression analysis was used for adjustment of confounders and bootstrap Confidence Interval was used to test for the occurrence of mediating effect.

RESULTS

Average age was 44.5 ± 16.0 years, 65% were females, 79% had type 2 DM and nearly 55% has had DM for more than 7 years and the average HbA1c was 8.9 ± 2.2%. Clinically significant DRD was reported by 37% of the participants, EB and RD in 40.8%, PD in 46.5%, and ID among 32.5%. Younger patients showed higher level of stress compared to older participants and patients with type 1 DM showed higher level of stress in all DRD domains. Only 46% of patients were defined as having satisfactory SRAT and improvement of SRAT significantly enhanced the glycemic control (r = -0.32, p < 0.01). DRD and low SRAT negatively correlated with HbA1c; increasing the DRD by one point may increase the HbA1c on average by 0.41 (C.I. 0.02-0.80) and will indirectly raise the HbA1c by 0.24 (C.I. 0.04-0.47) through the mediating effect of low SRAT.

CONCLUSION

DRD and low SRAT are commonly reported among DM patients and both are indirectly correlated. The mediating effect of low SRAT highlights the clinical role of DRD and clarifies the process by which distress affect the outcome of DM management.

Engaging Patient Advisory Boards of African American Community Members with Type 2 Diabetes in Implementing and Refining a Peer-Led Medication Adherence Intervention

African Americans are more likely than non-Hispanic whites to be diagnosed with and die from diabetes. A contributing factor to these health disparities is African Americans' poor diabetes medication adherence that is due in part to sociocultural barriers (e.g., medicine and illness misperceptions), which negatively affect diabetes management. In our prior work, we engaged with community stakeholders to develop and test a brief version of a culturally adapted intervention to address these barriers to medication adherence. The objective of this study was to elicit feedback to inform the refinement of the full 8-week intervention. We utilized a community-engaged study design to conduct a series of meetings with two cohorts of patient advisory boards of African Americans with type 2 diabetes who were adherent to their diabetes medicines (i.e., peer ambassadors). In total, 15 peer ambassadors were paired with 21 African American participants (i.e., peer buddies) to provide specific intervention support as peers and serve in an advisory role as a board member. Data were collected during nine board meetings with the patient stakeholders. A qualitative thematic analysis of the data was conducted to synthesize the findings. Feedback from the patient advisory board contributed to refining the intervention in the immediate-term, short-term, and long-term. The inclusion of African American community members living with type 2 diabetes on the advisory board contributed to further tailoring the intervention to the specific needs of African Americans with type 2 diabetes in the community.

The Weakness of Will: The Role of Free Will in Treatment Adherence

Chronic disease prevention and management requires a lifelong commitment and adherence to lifestyle modifications, monitoring of symptoms, medication use, and other forms of therapy. Treatment adherence is a crucial and complex concept in patient care provision, and it requires the voluntary active involvement of patients for the best possible outcome. Multiple factors, which may or may not be under the patient's control, can influence treatment adherence. However, adherence or non-adherence to a certain treatment is predominantly influenced by one's sense of agency, values, beliefs, attitudes, and willpower. It is evident that mental states appear to influence patients' decision-making, and the best treatment outcome occurs when a patient identifies their goals, needs, and desires and exercises their decision-making and free will during the course of receiving care. The role of healthcare providers is critical in promoting treatment adherence, thereby enhancing patient outcomes. Thus, this paper highlights the importance of promoting a sense of agency and integrating patients' values, beliefs, attitudes, and intentions during the provision of healthcare. It is indispensable to recognize the individual's ability and initiative to control and manage their illness in the face of challenging socioeconomic and cultural reality. On logical grounds, it is not enough to appreciate the value of free will and mental states, it is also essential to empower and cultivate an individual patient's willpower to make a well-informed, free decision based on their mental state for the most optimal treatment outcomes.

Using an exploratory sequential mixed methods design to adapt an Illness Perception Questionnaire for African Americans with diabetes: the mixed data integration process

Background

Although qualitative methods have been used to develop quantitative behavioral health measurements, studies rarely report on the exact development process of these questionnaires. In this methodological paper, we highlight the procedure of a mixed data integration process in using qualitative data to create quantitative questionnaire items.

Methods

We used an exploratory sequential mixed methods study design to culturally adapt the Illness Perception Questionnaire-Revised (IPQ-R) and address the sociocultural contexts of African Americans with type 2 diabetes. Forty African Americans with type 2 diabetes taking oral diabetes medication completed the qualitative focus groups and 170 participants completed the quantitative phase (surveys). Using the ‘building approach’ to integration, qualitative themes from the focus groups were matched to survey domains based on the self-regulatory model. Qualitative themes assessing perceptions of diabetes among African Americans were used to develop new survey items for a culturally adapted IPQ-R, as well as adapt original survey items.

Results

Important themes included the effect on friend/family relationships, lifestyle changes, food experiences (consequences domain), importance of medications (treatment control), comparisons with family members (illness coherence), fear, future worries, and anger (emotional representations). A new domain, ‘sociocultural influences’ was added to the adapted questionnaire based on qualitative themes of race and racism on provider roles, personal control, and community influences. Merging and integration of the qualitative and quantitative phases, (reported via a joint display) showed evidence of congruence between the illness perceptions from the qualitative focus groups and scores on the survey items.

Conclusion

The use of mixed methods allowed for the development of a robust and patient-centered questionnaire. Future research should consider psychometric testing of the adapted IPQ-R, so that it may be used in addressing illness perceptions among African Americans.

The Management of Diabetes in Everyday Life (MODEL) program: development of a tailored text message intervention to improve diabetes self-care activities among underserved African-American adults

Tailoring health-related materials is an effective mechanism to encourage behavior change; however, little research has described processes and critical characteristics for effective tailoring in underserved populations. The purpose of this study is to describe a process using input from content experts and lay patient advisors to tailor text messages focused on improving self-care behaviors of African-American adults with diabetes and identify characteristics of messages perceived to be most effective. An initial library of tailorable messages was created using theory-based approaches, expert opinion, and publicly available materials. A study-specific advisory council representing the program's intended population provided sequential individual and focus group review of a sample of draft messages focused on medication use, healthy eating, and physical activity. Messages were reviewed for content, tone, and applicability to African-American adults with diabetes from underserved communities. Based on this feedback, messages were revised and a final library of tailorable messages was constructed for use in a text messaging intervention. The initial library had over 5,000 tailorable messages. Participants preferred messages that included: (1) encouraging statements without condescension; (2) short sentences in lay language; (3) specific, actionable instructions; and (4) content relatable to daily activities of living. When possible, messages with similar themes should be repeated over short periods of time to improve the odds of material being absorbed and action being taken. Input from patient participants and advisors is essential for designing deeply tailored messages that honor the preferences, values, and norms of the population under study and promote health behavior change.

Issues Affecting Medication-Taking Behavior of People with Type 2 Diabetes in Indonesia: A Qualitative Study

PURPOSE

It has been widely acknowledged that non-adherence to medication among people with type 2 diabetes is a significant problem worldwide. Studies have suggested that non-adherence to medication may be caused by the complexity of issues surrounding medication use which further created burdens related to medication. However, studies on this topic in the Indonesian context were still limited. This study aimed to understand the experiences of people with type 2 diabetes in medication-taking and explore any practical issues that potentially affect their behavior when taking medication.

METHODS

Qualitative phenomenological study with semi-structured interviews was applied. The participants were purposefully recruited and selected from some primary healthcare facilities in Yogyakarta Province. The eligibility criteria included: diagnosed with type 2 diabetes by healthcare professionals for at least six months and were able to comprehend information. Information about the study was explained, and written informed consent was collected. The interviews were recorded, transcribed verbatim, and analyzed with a deductive qualitative content analysis method.

RESULTS

Fifty-one people with type 2 diabetes were involved in this study. Most of the participants were between 40 and 59 years old, and many of them were female and housewives. The thematic analysis found some practical issues that affected people's behavior in taking type 2 diabetes medication. These included individual's mealtime, characteristics of the medications, accessibility of healthcare services, experiences of side effects and social activities.

CONCLUSION

The practical issues identified in this study can be resolved by improving the role of healthcare providers in managing people with diabetes. Future research needs to be conducted to evaluate the effectiveness of interventions developed based on understanding of the practical factors identified.

Treatment of Patients with Prediabetes in a Primary Care Setting 2011-2018: an Observational Study

BACKGROUND

Over one third of American adults are at high risk for developing diabetes, which can be delayed or prevented using interventions such as medical nutrition therapy (MNT) or metformin. Physicians' self-reported rates of prediabetes treatment are improving, but patterns of actual referral, prescription, and MNT visits are unknown.

OBJECTIVE

To characterize treatment of prediabetes in primary care.

DESIGN

We conducted a retrospective cohort study using electronic health record data. We described patterns of treatment and used multivariable logistic regression to evaluate the association of patient factors and PCP-specific treatment rate with patient treatment.

PATIENTS

We included overweight or obese outpatients who had a first prediabetes-range hemoglobin A1c (HbA1c) during 2011-2018 and had primary care provider (PCP) follow-up within a year.

MAIN MEASURES

We collected patient characteristics and the following treatments: metformin prescription; referral to MNT, diabetes education, endocrinology, or bariatric medicine; and MNT visit. We did not capture within-visit physician counseling.

KEY RESULTS

Of 16,713 outpatients with prediabetes, 20.4% received treatment, including metformin prescriptions (7.8%) and MNT referrals (11.3%), but only 7.4% of referred patients completed a MNT visit. The strongest predictor of treatment was the patient's PCP's treatment rate. Some PCPs never treated prediabetes, but two treated more than half of their patients; 62% had no patients complete a MNT visit. Being younger or female and having higher body mass index or HbA1c were also positively associated with treatment. Compared to white patients, black patients were more likely to receive MNT referral and less likely to receive metformin.

CONCLUSIONS

Almost 80% of patients with new prediabetes never received treatment, and those who did receive referrals had very poor visit completion. Treatment rates appear to reflect provider rather than patient preferences.

Preliminary engagement of a patient advisory board of African American community members with type 2 diabetes in a peer-led medication adherence intervention

BACKGROUND

The Peers Supporting Health Literacy, Self-efficacy, Self-Advocacy, and Adherence (Peers LEAD) program is a culturally tailored educational-behavioral 8-week intervention that addressed psychosocial and sociocultural barriers to diabetes medication adherence in African Americans. A brief 3-week version of the Peers LEAD intervention used a community engagement approach to examine the feasibility and acceptability of the intervention amongst patient stakeholders.

MAIN BODY

African Americans who were adherent to their diabetes medicines were paired with those who were non-adherent to their medicines. Together, they participated in the group and phone-based medication adherence intervention. Input from this brief intervention was important for the design of the remainder weeks of the 8-week program. The intervention targeted negative beliefs about diabetes, use of diabetes medicines, and offering culturally tailored peer support to improve medication adherence in African Americans. To receive input in the development and implementation of the program, we worked with community advisors and a peer ambassador board of African Americans who were adherent to their diabetes medicines. The peer ambassador board and community advisors reviewed intervention materials to ensure they were understandable and appropriate for the community. As well, they provided feedback on the process for intervention delivery.

CONCLUSION

The active engagement of the peer ambassador board and community advisors led to a revised intervention process and materials for a medication adherence program for African Americans with type 2 diabetes.

Poor Medication Adherence in African Americans Is a Matter of Trust

The purpose of this paper was to explore the lack of medication adherence in the African American patient community. The paper will address myths that many African American patients believe related to type 2 diabetes, hypertension treatment, and natural remedies. Research has shown that the disparities in the acceptance of healthcare provider advice and prescriptions are a significant concern particularly in African American patients. The acceptance of a provider's diagnosis and subsequent intervention can vary based on several issues including healthcare access, patient preferences, trust of a provider, and treatment recommendations. Patient influences can range from their ability to trust the provider (and what he/she says) to following through with their advice. Several studies have looked at the beliefs and misconceptions some African Americans hold regarding the treatment of hypertension and diabetes with some showing a preference for "natural remedies." This paper will leverage a literature review to seek out myths from African American patients to understand why they are dealing with challenges related to adherence with medication. The searches identified 58 research papers. The study applied an inductive content analysis approach to assess the research papers and identify themes. The barriers identified in this study include disbelief of the diagnosis, distrust for medication, mistrust for physicians and healthcare system, belief in alternative medicine, cultural/generation norms, and access/affordability of care. One of the most prominent factors that crossed all barriers was medical mistrust.

Promoting Mindfulness in African American Communities

African Americans report higher rates of chronic stress compared to non-Hispanic Whites. Consequently, chronic stress contributes to disproportionately higher rates of poor health outcomes among African Americans. Mindfulness meditation is a well-established and studied strategy to reduce stress and potentially improve health outcomes. However, the practice of mindfulness meditation is largely underutilized in African American communities despite its potential health benefits. In this commentary, we will discuss the relevance of mindfulness interventions, limited research available, reasons for low representation, and cultural adaptations for mindfulness meditation in African American communities. We also provide additional strategies to guide future mindfulness research that target African Americans.

"Tell Me About Your Child": A Grounded Theory Study of Mothers' Understanding of Language Disorder

Purpose The purpose of this study was to generate a theory grounded in data explaining caregivers' understanding of their child's language disorder and the perceived role of speech-language pathologists in facilitating this knowledge. Method This study employed grounded theory as a conceptual framework. Qualitative data were generated based on semistructured interviews conducted with 12 mothers of children who had received speech-language pathology services. Results The following themes emerged from the data analysis: (a) Many mothers reported receiving confusing or irrelevant diagnostic terms for language disorder, (b) mothers of children with language disorders were distressed about their children's language problems, (c) mothers did not always trust or understand their children's speech-language pathologist, and (d) mothers were satisfied with the interventions their child had been receiving. Mothers described their children's language disorder using a total of 23 labels, most of which were not useful for accessing meaningful information about the nature of their child's communication problem. Generally, mothers reported they did not receive language-related diagnostic labels from speech-language pathologists for their child's language disorder. Conclusions Two theories were generated from the results: (a) Lack of information provided to mothers about their child's language disorder causes mothers psychological harm that appears to be long lasting. (b) Difficulties in successfully relaying information about language disorders to parents result in negative perceptions of speech-language pathology. Implications and future directions are discussed. Supplemental Material https://doi.org/10.23641/asha.12177390.

What Predicts Different Kinds of Nonadherent Behavior in Elderly People With Parkinson's Disease?

Background: Detailed knowledge about nonadherence to medication could improve medical care in elderly patients. We aimed to explore patterns and reasons for nonadherence in people with Parkinson's disease (PD) aged 60 years and older.

Methods: Detailed clinical data and adherence (German Stendal Adherence with Medication Score) were assessed in 230 patients with PD (without dementia). Descriptive statistics were used to study reasons for nonadherence in detail, and general linear models were used to study associations between clusters of nonadherence and clinical parameters.

Results: Overall, 14.2% (n = 32) of the patients were fully adherent, 66.8% (n = 151) were moderately nonadherent, and 19.0% (n = 43) showed clinically meaningful nonadherence. In the multivariable analysis, nonadherence was associated with a lower education level, higher motor impairment in activities of daily living, higher number of medications per day, and motor complications of PD. Three clusters of nonadherence were observed: 59 (30.4%) patients reported intentional nonadherence by medication modification; in 72 (37.1%) patients, nonadherence was associated with forgetting to take medication; and 63 (32.5%) patients had poor knowledge about the prescribed medication. A lower education level was mainly associated with modification of medication and poorer knowledge about prescribed medication, but not with forgetting to take medication. Patients with motor complications, which frequently occur in those with advanced disease stages, tend to be intentionally nonadherent by modifying their prescribed medication. Increased motor problems and a higher total number of drugs per day were associated with less knowledge about the names, reasons, and dosages of their prescribed medication.

Conclusions: Elderly patients with PD report many reasons for intentional and non-intentional nonadherence. Understanding the impact of clinical parameters on different patterns of nonadherence may facilitate tailoring of interventions and counseling to improve outcomes.

Behavioral Theory: The Missing Ingredient for Digital Health Tools to Change Behavior and Increase Adherence

Behavioral theory is an important factor for designing digital health tools for diabetes to increase adherence to treatment. Many digital health products have not incorporated this method for achieving behavior change. This oversight might explain the disappointing outcomes of many products in this class. Four theories reported to be capable of enhancing the performance of digital health tools for diabetes include (1) Integrate, Design, Assess, and Share (IDEAS); (2) the Behaviour Change Wheel; (3) the Information-Motivation-Behavioral skills (IMB) model; and (4) gamification. Well-designed digital health tools are most likely to be effective if they are deployed in a patient-centered care setting established upon principles of sound behavioral theory. Behavioral theory can increase the effectiveness of digital tools and promote a receptive environment for their use.

Patient Perspectives on Factors Influencing Medication Adherence Among People with Coronary Heart Disease (CHD) and CHD Risk Factors

BACKGROUND

Few qualitative studies have explored factors influencing medication adherence among people with coronary heart disease (CHD) or CHD risk factors. We explored how factors related to the patient (e.g. self-efficacy), social/economic conditions (e.g. social support and cost of medications), therapy (e.g. side effects), health condition (e.g. comorbidities), and the healthcare system/healthcare team (e.g. support from healthcare providers and pharmacy access) influence medication adherence, based on the World Health Organization Multidimensional Adherence Model (WHO-MAM).

METHODS

We conducted 18 in-depth qualitative interviews from April to July 2018 with ambulatory care patients aged ≥45 years (8 black men, 5 black women, 2 white men, and 3 white women) who were using medications for diabetes, hypertension, dyslipidemia and/or CHD. We used thematic analysis to analyze the data, and sub-themes emerged within each WHO-MAM dimension.

FINDINGS

Patient-related factors included beliefs about medications as important for self and faith; the desire to follow the advice of family, friends, and influential others; and self-efficacy. Social/economic factors included observations of social network members and information received from them; social support for medication adherence and pharmacy utilization; and economic influences. Therapy-related barriers included side effects and medicine schedules. Only a few participants mentioned condition-related factors. Healthcare system/healthcare team-related factors included support from doctors and pharmacists; and ease of pharmacy access and utilization.

CONCLUSION

These results underscore the need for multidimensional interventions aimed at improving medication adherence and overall health of patients with CHD and CHD risk factors.

A cultural adaptation and validation study of a self-report measure of the extent of and reasons for medication nonadherence among patients with diabetes in Singapore

BACKGROUND

This self-report measure is a new instrument to measure the extent of and reasons for medication adherence separately. However, few studies have assessed its psychometric properties in diabetic patients and also in Asian populations.

OBJECTIVES

To validate this self-report measure in diabetic patients in Singapore.

METHODS

We collected data prospectively using a questionnaire among 393 diabetic patients from hospitals in Singapore from July 2018 to January 2019. Using the COnsensus-based Standards for the selection of health Measurement INstruments framework, we assessed face validity, internal consistency, test-retest reliability, structural validity, and measurement error. We tested four a priori hypotheses on correlation of extent score with patient-reported outcome measures to assess construct validity. We examined cross-cultural validity via measurement invariance across gender, age groups, and languages.

RESULTS

We performed cognitive interviews with 30 consenting English-literate, Chinese-literate, and Malay-literate (10 patients per language) diabetic patients (age range 48-76 years, 53% male, disease duration range 1-30 years) and face validity was supported. Among 393 patients (mean age: 59.4±12.2 years, 50.9% female, 52.4% Chinese), we showed moderate internal consistency (Cronbach's alpha =0.67) and test-retest reliability (intra-class coefficient=0.56 [95% CI 0.37-0.70]). We calculated smallest detectable change as 0.80. We established construct validity by meeting all four hypotheses. We showed structural validity as confirmatory factor analysis confirmed a one-factor model, with excellent fit statistics (Comparative Fit Index=1.0; Tucker-Lewis Index=1.0; Root Mean Square Error of Approximation<0.001; Standardized Root Mean Residuals<0.001). Analysis of cross-cultural validity supported configural invariance model but not metric invariance and scalar invariance model. Caution must be taken against directly comparing extent scores across gender, age groups, and languages.

CONCLUSION

This self-report measure is valid and reliable in measuring medication adherence in diabetic patients in Singapore.

Utilizing the common sense model to explore African Americans' perception of type 2 diabetes: A qualitative study

Illness perceptions, which are likely influenced by patients' cultural contexts, are associated with disease self-management and adherence. African American patients perceptions of type 2 diabetes is not well understood and no known studies has used a comprehensive evidence-based theoretical framework to explore what AAs with type 2 diabetes know, believe, and think about type 2 diabetes. Understanding perceptions of an illness shared by a group of people will be useful in developing culturally-appropriate interventions targeted to the needs of the community. The purpose of this study is to explore African Americans' perceptions of type 2 diabetes based on the common sense model of illness and self-regulation. Using a phenomenology qualitative approach and purposive sampling, 40 African American men and women, age 45-60 years old with diagnosed type 2 diabetes at least one year prior, and who took at least one prescription diabetes medication, participated in six semi-structured 90-minute focus groups conducted in a private space. Qualitative content analysis was conducted to explore African Americans beliefs about type 2 diabetes. Participants expressed that historical issues, e.g., slavery, healthcare providers, the government, and God influenced how they developed diabetes. Participants reported a loss of autonomy, a change of their identity as an employee, a social individual and sexual person, as well as anger and frustration due to having diabetes. Diabetes made the African American family bonding experience of eating difficult, and the disease diminished their cultural experiences. Concerns about diabetes ranged from fear of death and amputations to the inability to prevent the disease among their children/grandchildren. Participants perceived that medications, faith in God, and positive thinking about survival helped control diabetes. Conclusions: Improved diabetes self-management and medication adherence may depend on the meaning African Americans attach to diabetes, available psychosocial support for managing diabetes, and African Americans experience with diabetes.

Treatment adherence in systemic sclerosis: A cross-sectional study

BACKGROUND

Treatment adherence is an important medical and pharmaco-economical phenomenon, influenced by multiple variables. Treatment adherence in systemic sclerosis (SSc) has been poorly studied.

OBJECTIVE

The aim of the present study was to assess treatment adherence in SSc patients and to identify factors associated with good and poor adherence.

METHODS

We conducted a monocentric, cross-sectional, observational study. Treatment adherence was evaluated by the Compliance Questionnaire of Rheumatology (CQR). The necessity of treatment and concerns about treatment were investigated using the Beliefs about Medicines Questionnaire-Specific (BMQ-S). The Illness Perception Questionnaire-Revised (IPQ-R) assessed illness perceptions. Disease-related characteristics were collected retrospectively.

RESULTS

A total of 66 patients were enrolled in this study. Of these, 47 (71.2%) had a weighted CQR score of ≤80% ("poor adherence") and 19 (28.8%) had a weighted CQR score of >80% ("good adherence"). No significant relationship between demographic, clinical or psychological factors and overall adherence could be found, except with the IPQ subscale "timeline acute/chronic" (p = 0.042). Our patient population estimated the necessity of their medication high (mean necessity score 20.5), with moderate concern beliefs (mean concern score 15.1). Subjective adherence, as self-reported by patients, was high.

CONCLUSIONS

This study demonstrated low treatment adherence rates in SSc patients. We could not identify demographic, clinical or psychological factors associated with treatment adherence, except with the IPQ subscale "timeline acute/chronic". This suggests a correlation between poor adherence and the belief that the disease will be chronic without improvement over time. Symptom relief was an important motivating factor for taking medication. The treatment necessity was scored higher than treatment concerns, but the necessity beliefs were not associated with adherence.
