Abstract
Background A diagnosis of Alzheimer's disease (AD) is a crucial moment in an individual's existence and represents a major life change that often results in psychological distress, diminish of perceived quality of life, and loss of independence. It is important to better understand the emotional experience of people with dementia to intervene according to their specific needs. Objective The aim of the research was to get insight to the emotional experience of people with AD shortly after its discovery and the consequences thereof. Methods A qualitative exploratory design was engaged, and in-depth interviews were conducted with ten French-speaking participants over 70 years recently diagnosed. Interviews were guided by Heideggerian phenomenology about movements in the worldview of individuals. The transcribed data was subjected to interpretative phenomenological analysis. Results Following the diagnosis, participants experienced either shock or denial. Emotions felt were unpleasant and disturbing for most of them. Especially when participants were confronted with news concerning the illness, they experienced incomprehension. They engaged in an oscillatory motion of connection and disconnection to establish new meanings of their worldview. Thinking about the past seemed to diminish their worries, to reinforce the possibility to fulfil a significant place in their existence and to maintain their autonomy. Conclusions When participants could express their emotional experience and their concerns, they regained a sense of control in their life that seemed du reduce their distress. With this insight, intervention could be adapted to the specific needs of people with AD to enhance their self-determination and quality of life.

Abstract
Background Older adults are at increased risk of cognitive impairments including Alzheimer's disease dementia. Legally authorized representatives (LARs) can provide informed consent when a participant is no longer able to, but little is known about barriers to incorporating them in research. Objective Explore reasons for not asking and documenting participant decisions to appoint LARs among researchers conducting clinical intervention trials studying older adults or individuals with cognitive impairments. Methods Mixed method design consisting of a survey (N = 1,284) and qualitative interviews (N = 40) regarding barriers to incorporating LARs. Participants were principal investigators and clinical research coordinators. Results 37% (N = 469) had not asked and documented participant decisions about appointing LARs in the prior year. They had significantly lower confidence in resources available to incorporate LARs and lower positive attitudes compared to their counterparts who had done so. The majority (83%) had no trials studying individuals with cognitive impairments and reported LARs were not applicable. A minority (17%) had at least one trial studying individuals with cognitive impairments and reported being unaware of LARs. Qualitative findings indicate discomfort broaching a sensitive topic especially with individuals who are not yet impaired. Conclusion Resources and education to increase awareness and knowledge of LARs are needed. Researchers studying older adults should, at minimum, have the knowledge and resources to incorporate LARs when necessary. Stigma and discomfort discussing LARs will need to be overcome, as early proactive discussions before a participant loses decisional capacity could enhance participant autonomy and facilitate recruitment and retention of older adults to research.

Abstract
Recruitment and retention of participants for pain-related neuroimaging research is challenging and becomes increasingly so when research participants have a diagnosis of Alzheimer's disease and related dementias (ADRD). This article shares the authors' recommendations from several years of successful recruitment and completion of pain-related neuroimaging studies of people living with ADRD and includes supportive literature. While not an exhaustive list, this review covers several topics related to recruitment and retention of participants living with ADRD, including community engagement, capacity to consent, dementia diagnostic criteria, pain medication and other study exclusion criteria, participant and caregiver burden, communication concerns, and relationships with neuroimaging facilities. Threaded throughout the paper are important cultural considerations. Additionally, we discuss implications of the coronavirus (COVID-19) pandemic for recruitment. Once tailored to specific research study protocols, these proven strategies may assist researchers with successfully recruiting and retaining participants living with ADRD for pain-related neuroimaging research studies toward improving overall health outcomes.

Abstract
BACKGROUND Best approaches for retaining research participants in Alzheimer's disease cohort studies are understudied. OBJECTIVE Using data from the National Alzheimer's Coordinating Center Uniform Data Set, we evaluated the associations of unique strategies with participant retention across Alzheimer's Disease Research Centers and explored potential effect modification by race, ethnicity and diagnostic group. METHODS We examined retention at the first follow-up visit among participants enrolled during 2015-2017. Structured surveys ascertained 95 retention tactics among 12 strategies. Strategy-specific summary scores were created based on the number of implemented tactics for each strategy and grouped into tertiles. Generalized estimating equations were constructed to evaluate associations between strategy scores and the odds of retention, controlling for age, sex, education, study partner type, marital status, visit length, battery length, diagnostic group, race and ethnicity. Separate models were stratified by race, ethnicity and diagnostic group. Effect modification was formally tested with interaction terms. RESULTS Among 5,715 total participants enrolled, 4,515 were Non-Hispanic White (79%), 335 were Hispanic/Latino (6%), 651 were Non-Hispanic Black (11%), and 214 were Non-Hispanic Asian (4%). Compared to the lowest tertile of scores, the highest tertile of scores involving improvement in study personnel and communication of study requirements and details were associated with 61% higher odds of retention in fully adjusted models (adjusted Odds Ratios [aOR] = 1.61, 95% Confidence Interval [CI] = 1.05-2.47 and aOR = 1.55, 95% CI = 1.03-2.35, respectively). We did not find evidence for effect modification. CONCLUSION In the setting of limited resources, specific retention strategies may be more valuable than others.

Early Implementation and Evaluation of StepUp for Dementia Research: An Australia-Wide Dementia Research Participation and Public Engagement Platform. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182111353. [PMID: 34769871 PMCID: PMC8583565 DOI: 10.3390/ijerph182111353] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 10/21/2021] [Accepted: 10/24/2021] [Indexed: 11/16/2022]
Abstract
Recruiting participants for dementia research takes time. For those who are interested, opportunities to participate can be ad hoc. Delays in finding the right participants can result in studies taking longer to deliver, often requiring funding extensions, and ultimately increasing the cost and limiting the effectiveness of research and evaluation. To address these issues, a digital platform, StepUp for Dementia Research, was developed in 2019 and evaluated through ongoing data analytics, researcher feedback and annual volunteer surveys in 2019 and 2021. Using innovative matching technology, StepUp provides volunteers with an opt-in, secure way of registering interest in dementia studies and allows researchers to access matched volunteers in Australia. As of June 2021, 1070 volunteers registered (78% female), and 25 organizations became ‘champions’ for StepUp promotion. Of 122 registered researchers, 90 completed training. Forty studies from 17 research/health institutions recruited participants using StepUp. The evaluation demonstrated program feasibility and recruitment efficiency with a high level of satisfaction from users. Evaluation outcomes highlighted disparities in public participation in dementia research (e.g., gender, education and race/ethnicity) and provided valuable insights for further enhancements of StepUp. A concerted and strategic effort is needed by leading registries such as StepUp to ensure narrowing volunteer participation gaps in dementia research.

Abstract
BACKGROUND There is a pressing need to increase enrollment and representation in Alzheimer's disease and related dementia (ADRD) research. Current recruitment approaches focus largely on clinic and community settings, with minimal engagement of acute care environments despite their broad use across diverse populations. The objectives of this study were to examine views, preferences, and recommendations regarding acute care-based ADRD research recruitment among persons with dementia and their caregivers. METHODS The authors conducted semistructured interviews with recently hospitalized persons with dementia (N=3) and family caregivers (N=28). Interviews were analyzed using thematic analysis. FINDINGS All participants endorsed acute care as an appropriate time for recruitment into ADRD research studies and identified important elements of an appropriately tailored recruitment approach and an interpersonally effective research staff. Participants emphasized that this approach should consider the acute care context with respect to participant situation, uncertainty, and timing. Participant suggestions informed the design of a 5-step process to guide ADRD research recruitment in the context of acute care. DISCUSSION Findings provide valuable insights from people with dementia and their caregivers regarding opportunities for research engagement surrounding acute care and can inform expanded recruitment in these settings.

Abstract
Background
Registries are an essential research tool to investigate the long-term course of diseases and their impact on the affected. The project digiDEM Bayern will set up a prospective dementia registry to collect long-term data of people with dementia and their caregivers in Bavaria (Germany) supported by more than 300 research partners.
Objective
The objective of this article is to outline an information technology (IT) architecture for the integration of a registry and comprehensive participant management in a dementia study. Measures to ensure high data quality, study governance, along with data privacy, and security are to be included in the architecture.
Methods
The architecture was developed based on an iterative, stakeholder-oriented process. The development was inspired by the Twin Peaks Model that focuses on the codevelopment of requirements and architecture. We gradually moved from a general to a detailed understanding of both the requirements and design through a series of iterations. The experience learned from the pilot phase was integrated into a further iterative process of continuous improvement of the architecture.
Results
The infrastructure provides a standardized workflow to support the electronic data collection and trace each participant's study process. Therefore, the implementation consists of three systems: (1) electronic data capture system for Web-based or offline app-based data collection; (2) participant management system for the administration of the identity data of participants and research partners as well as of the overall study governance process; and (3) videoconferencing software for conducting interviews online. First experiences in the pilot phase have proven the feasibility of the framework.
Conclusion
This article outlines an IT architecture to integrate a registry and participant management in a dementia research project. The framework was discussed and developed with the involvement of numerous stakeholders. Due to its adaptability of used software systems, a transfer to other projects should be easily possible.

Abstract
The objective of this study was to explore the feasibility and preliminary effectiveness of the Lifestyle-Integrated Functional Exercise for People with Dementia (LiFE4D) on health-related physical fitness, cognitive function, physical activity, and respiratory and upper limb functions. A randomized controlled pilot study was conducted (control group: usual care; experimental group: usual care and LiFE4D). The feasibility of LiFE4D was determined considering recruitment, protocol acceptability, adherence, and safety. Measures of health-related physical fitness, cognitive function, physical activity, and respiratory and upper limb functions were assessed at the baseline and 3 months. Twelve participants (8 [66.7%] female, 82 [72.2-84] years) were included, six per group. Recruitment was challenging. LiFE4D was acceptable with excellent adherence and no major adverse events. Cardiorespiratory endurance (effect size = 1.64, 95% confidence interval [CI; 0.33, 2.95]) and balance (effect size = 1.46, 95% CI [0.19, 2.73]) improved after LiFE4D. LiFE4D seems to be feasible and safe, and it shows potential to significantly improve the health-related physical fitness of people with dementia.

Abstract
Clinical Alzheimer's disease (AD) trials currently face a critical shortfall of thousands of eligible participants, which inflates the duration and cost of the clinical study as well as threatens the scientific merit of promising clinical interventions. This recruitment crisis is further compounded by the fact that underrepresented and marginalized populations-particularly those identifying as a racial or ethnic minority, those with low socioeconomic status, or living in rural areas-have been historically underrepresented in ongoing AD clinical trials despite overwhelming evidence that such populations are at increased risk for developing dementia. As a result of various recruitment barriers, current AD clinical studies frequently reflect a decreasingly representative segment of the US population, which threatens the overall generalizability of these findings. The current narrative review provides an updated examination and critique of common recruitment barriers and potential solutions, as well as a discussion of theoretical approaches that may address barriers disproportionately experienced by underrepresented communities. AD clinical researchers are encouraged to take purposive action aimed at increasing diversity of enrolled AD clinical trial cohorts by actively identifying and quantifying barriers to research participation-especially recruitment barriers and health disparities that disproportionately prevent underrepresented and marginalized populations from participating in research. Furthermore, researchers are encouraged to closely track which individuals who express interest in AD research ultimately enroll in research studies to examine whether AD research participation is appropriately representative of the intended population for whom these new and novel AD interventions are being designed.

Comparing fluid biomarkers of Alzheimer's disease between African American or Black African and white groups: A systematic review and meta-analysis. J Neurol Sci 2020; 421:117270.

Abstract
RATIONALE Biomarker research for Alzheimer's disease (AD) has grown rapidly in recent years, ensuing the integration of the AD fluid biomarker profile: Aβ1-42, t-tau, and p-tau181, into clinical and research criteria. However, current insights of AD arise almost exclusively from studies on white individuals. Some studies have revealed that epidemiology, clinical features, and genetics of AD show variations between individuals from black and white backgrounds, conveying the importance of ethnoracial differences, and the possibility of such differences also influencing AD biomarker levels. This systematic review explored whether AD fluid biomarker levels differ between African American (AA) or Black African and white groups. AIM To compare AD fluid biomarkers (Aβ1-42, p-tau181, and t-tau) levels between AA or Black Africans and white individuals. METHOD PubMed, Scopus, and other sources were explored for studies that quantified AD biomarkers in biological fluid from whites and AA or Black African groups. Meta-analyses were performed to find the standardized mean difference for biomarkers that were quantified in ≥3 studies. RESULTS Five studies were included; studies on Black Africans were not found. The meta-analyses found CSF t-tau and p-tau181 were consistently lower in AA than white individuals, in samples with normal cognition or with mild cognitive impairment/dementia. CONCLUSIONS The meta-analyses found significant differences for CSF tau between AA and white individuals with normal cognition and within the dementia spectrum, expressing the importance of taking into account ethnoracial factors when interpreting CSF AD biomarkers levels. However, the generalisability of these differences is restricted by small samples' size, lack of unified methodologies and recruitment's biases within studies; further large multicentre studies with harmonized protocols and sufficient power are imperative to investigate the extent of ethnoracial differences across the spectrum of cognitive decline, with vaster efforts necessary to diversify recruitment.

Abstract
Objectives: There is currently little known about why people decline to participate in dyadic, psychosocial dementia research. This interview study aims to explore the reasons why people declined to participate in the Valuing Active Life in Dementia research trial. Methods: Ten family carers of people with dementia, who were part of a dyad that had declined to take part in the randomised controlled trial, participated in qualitative telephone interviews to explore their reasons for declining. Inductive thematic analysis was used to identify themes. Findings: Two themes with related sub-themes were identified: (1) Protectiveness – protecting the person with dementia, themselves as carers and their current lifestyle; (2) ‘It’s not for us’ – the time commitment, and the possible unsuitability of the intervention, was seen to outweigh the perceived benefit of taking part. People with dementia were not always involved in the decision-making process, with carers stating the decision not to participate was made in the usual way as all their decisions. No apparent differences between the spousal and the child carers were apparent in the small sample. Conclusion: Recruitment to randomised controlled trials can be considered difficult or unfair because some participants will miss out on the desired intervention. However, this study shows that concern about the time and inconvenience of being involved in the trial can put people off research participation. Identifying possible reasons for declining research participation contributes to the design of future trials and recruitment strategies, so that the potential benefit is considered relative to the time and effort involved. Offering research opportunities to people with dementia and their families at the right stage of the dementia trajectory for their needs, facilitating personalised recruitment strategies with finely tailored researcher communication skills should help maximise recruitment, reduce attrition and deliver a more successful trial.

Abstract
BACKGROUND AND OBJECTIVES Human research ethics statements support equitable inclusion of diverse groups. Yet older people are under-represented in clinical research, especially those with impaired decision-making capacity. The aim of this study was to identify perspectives and experiences of older persons and their caregivers of research participation with impaired decision-making capacity. RESEARCH DESIGN AND METHODS Scoping review of literature and online sources in January-February 2019 (updated June 2020) according to Joanna Briggs Institute methodology and PRISMA Extension for Scoping Reviews. English-language peer-reviewed research articles and Australian online narratives were included. Data were tabulated and narratively synthesized. RESULTS From 4171 database records and 93 online resources, 22 articles (2000-2019, 82% United States, 16 first authors) and one YouTube webinar (2018) were initially included; updated searches yielded an additional article (2020) and YouTube webinar (2020). Studies were heterogeneous in terminology, methods and foci, with hypothetical scenarios, quantitative analyses and examination of proxy consent predominating. Participants (n=7331) were older persons (71%), caregivers of older persons with dementia/cognitive impairment (23%) and older persons with dementia/cognitive impairment (6%). Synthesis identified two themes: willingness to participate and decision-making approaches. DISCUSSION AND IMPLICATIONS Research participation by older persons with dementia may be optimized through reducing risks and burdens and increasing benefits for participants, greater consumer input into study development, and shared and supported decision-making. Older persons' and caregivers' perspectives and experiences of research participation with impaired decision-making capacity require investigation in a greater range of countries and conditions other than dementia, and dissemination through more varied media.

Withers M, Sayegh P, Rodriguez-Agudelo Y, Ernstrom K, Raman R, Montoya L, Zuno-Reyes A, Mosieri C, Matute E, Ringman JM. A mixed-methods study of cultural beliefs about dementia and genetic testing among Mexicans and Mexican-Americans at-risk for autosomal dominant Alzheimer's disease. J Genet Couns 2019; 28:921-932. [PMID: 31207006 PMCID: PMC7500864 DOI: 10.1002/jgc4.1133] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2018] [Revised: 04/30/2019] [Accepted: 05/06/2019] [Indexed: 01/04/2023]
Abstract
Trials to prevent autosomal dominantly inherited Alzheimer's disease (ADAD) are critical and timely. However, cultural beliefs about AD and genetic testing may preclude informed consent and participation, especially among racial/ethnic minorities. This mixed-methods study examines cultural beliefs about AD and genetic screening among at-risk populations of Mexican heritage. We surveyed 86 Mexican and 37 Mexican-American family members of patients with ADAD and interviewed 18 respondents in Mexico to explore perceptions and knowledge regarding AD and genetic testing. While most respondents understood that AD is inherited in their families, they also had limited understanding of the genetic mechanisms behind AD. Many believed that AD is a normal part of aging or that it is a mental illness caused by bad habits. However, beliefs that AD is caused by a curse or God's will were uncommon. The interviews demonstrated that very few at-risk respondents understood their own risk for harboring the mutation causing AD in their family. Once informed, most expressed a strong interest in genetic testing, largely motivated by the desire to be better prepared for the development of AD. Health professionals treating and investigators enrolling members from families with ADAD cannot assume that they fully understand the nature of the illness; therefore, providers should provide comprehensive information about ADAD and genetic testing.

Abstract
BACKGROUND Public and patient involvement (PPI) is now established in dementia research. Barriers and facilitators to engagement from family carers and people in early stages of dementia have been explored. However, specific barriers and facilitators to co-research with people with dementia have not previously been investigated. OBJECTIVE To discover the facilitators of, and barriers to, involving people with dementia as co-researchers, from the perspectives of people with dementia, gatekeepers (family caregivers, ethics committee members, service providers) and researchers. DESIGN Thematic analysis of data from individual interviews about the co-research experience. RESULTS Four themes emerged from interviews with 19 participants (five people with dementia): "getting one's head round it" (assumptions about research and dementia; different forms of language); practicalities (eg transport; accessibility of communication); "this feeling of safety" (perceptions of danger, protectiveness and opportunities for building trust); and motivations ("making a difference" and "keeping doing"). CONCLUSIONS Findings both replicate and extend previous knowledge on PPI in dementia. Cognitive capacity of potential co-researchers with dementia is only a part of the picture, with attitudes and expectations of researchers, gatekeepers and people with dementia also forming barriers. Researcher education, adequate resourcing, and both creativity and flexibility are needed to support recruitment of co-researchers with dementia and to enable meaningful co-research.

Abstract
INTRODUCTION Current pharmacological interventions for Alzheimer's dementia delay symptom progression for about a year. Although the outcomes in earlier disease states may include changes in biomarkers, the clinical effectiveness of any intervention can ultimately only be assessed by a patient's self-reported well-being. A better understanding of earlier manifestations of Alzheimer's disease and the drive for relevant outcome measures, allied to technological advances in artificial intelligence, have mediated the electronic Person-Specific Outcome Measure (ePSOM) development program. METHODS There are 4 sequential stages in the ePSOM development program-(1) literature review, (2) focus group study, (3) national survey, and (4) development of an app for capturing person-specific outcomes. Here, we report the overall approach to the program incorporating our literature review on patient-reported outcome measures and patient preferences in the Alzheimer's disease population. RESULTS Alzheimer's disease trials do not use any patient-reported outcome measures. Quality of life measures are often used as proxies for this, but they do not capture individual needs. Therefore, trials currently fail to reflect the participant's aspirations for effect but rather default to clinicostatistical measure of cognition and function. There is no implementation of patient preferences despite evidence that understanding preferences may influence adherence to treatment. DISCUSSION It is important to consider preferences for an intervention and use PROMs for the measure of effectiveness given that both risk and benefit are judged by the recipient of the treatment. The ePSOM development program will deliver the methodology for incorporating meaningful outcomes in clinical trials to expand upon current biological and clinical measurements of effectiveness.

Abstract
OBJECTIVES This study describes the process evaluation of the experience sampling method (ESM) intervention 'Partner in Sight' for spousal caregivers of people with dementia. The aim was to determine internal and external validity of the intervention and provide information for future implementation in clinical practice. METHOD Qualitative and quantitative data on sampling quality (recruitment and randomization, reach) and intervention quality (relevance and feasibility, adherence to protocol) were evaluated using descriptive statistics and conventional content analysis. RESULTS The participation rate included 31.4%. Due to recruitment difficulties and time constraints the original goal to include 90 caregivers was not met. The intervention was largely performed according to protocol and well received by the participants. Overall, the ESM-derived feedback was considered supportive and increased participants' awareness of their feelings and behavior. A large variance was found in the extent to which caregivers applied the feedback into their daily lives. The importance of the personal coach to provide face-to-face feedback and stimulate caregivers to implement new insights into their daily lives was emphasized. Suggestions for improvement were to reduce the time intensity of the program, to better tailor the program content to one's personal situation, and to improve the ESM device. CONCLUSION Although recruitment barriers were encountered, results indicate that future implementation of the ESM intervention 'Partner in Sight' is likely to be feasible in regular health care. If the intervention turns out to be (cost-) effective, a fine-tuned version of the program could be a valuable addition to the current health care system.

Abstract
INTRODUCTION Understanding the prevalence of beliefs, attitudes, and expectations about Alzheimer's disease dementia in the public could inform strategies to mitigate stigma. METHODS Random sample of 317 adults from the U.S. public was analyzed to understand reactions toward a man with mild-stage Alzheimer's disease dementia. RESULTS In adjusted analyses, over half of respondents expected the person to be discriminated against by employers (55.3%; 95% confidence interval [CI] = 47.0-65.2) and be excluded from medical decision-making (55.3%; 95% CI = 46.9-65.4). Almost half expected his health insurance would be limited based on data in the medical record (46.6%; 95% CI = 38.0-57.2), a brain imaging result (45.6%, 95% CI = 37.0-56.3), or genetic test result (44.7%; 95% CI = 36.0-55.4). DISCUSSION Public education and policies are needed to address concerns about employment and insurance discrimination. Studies are needed to discover how advances in diagnosis and treatment may change Alzheimer's disease stigma.

Abstract
Neuroimaging is advancing a new definition of Alzheimer's disease (AD). Using imaging biomarkers, clinicians may begin to diagnose the disease by identifying pathology and neurodegeneration in either cognitively impaired or unimpaired adults. This "biomarker-based" diagnosis may allow clinicians novel opportunities to use interventions that either delay the onset or slow the progression of cognitive decline, but it will also bring novel challenges. How will changing the definition of AD from a clinical to a biomarker construct change the experience of living with the disease? Knowledge of AD biomarker status can affect how individuals feel about themselves (internalized stigma) and how others judge them (public stigma). Following a review of AD stigma, we appraise how advances in diagnosis may enable or interrupt its transfer from clinical to preclinical stages and then explore conceptual and pragmatic challenges to addressing stigma in routine care.

Abstract
The general public's views can influence whether people with Alzheimer's disease (AD) experience stigma. The purpose of this study was to understand what characteristics in the general public are associated with stigmatizing attributions. A random sample of adults from the general population read a vignette about a man with mild Alzheimer's disease dementia and completed a modified Family Stigma in Alzheimer's Disease Scale (FS-ADS). Multivariable ordered logistic regressions were used to examine relationships between personal characteristics and FS-ADS ratings. Older respondents expected that persons with AD would receive less support (OR = 0.82, p = .001), have social interactions limited by others (OR = 1.13, p = .04), and face institutional discrimination (OR = 1.13, p = .04). Females reported stronger feelings of pity (OR = 1.57, p = .03) and weaker reactions to negative aesthetic features (OR = 0.67, p = .05). Those who believed strongly that AD was a mental illness rated symptoms more severely (OR = 1.78, p = .007). Identifiable characteristics and beliefs in the general public are related to stigmatizing attributions toward AD. To reduce AD stigma, public health messaging campaigns can tailor information to subpopulations, recognizable by their age, gender, and beliefs.

Abstract
Background Low participation in research is one of the key challenges to advancing understanding of dementia, and improving the care and treatment of those who live with this condition. Nurses and nurse researchers play a vital role in recruiting people with dementia to studies, as several countries including the United States and the United Kingdom set national targets and develop initiatives to encourage more people with dementia to take part in research. Aim To highlight the challenges to recruiting people with dementia to studies, and to identify strategies that nurses, and in particular, nurse researchers can use for overcoming them. Our focus is primarily on the role of nurses in recruiting people with dementia to dementia studies, but much of the discussion will apply to other health professionals involved in the recruitment of people with dementia to research more generally. Discussion Challenges discussed include a lack of awareness about research participation opportunities and a suitable study partner. We discuss how the nurses’ role is to ensure that recruitment practices are personalised and responsive to participants’ needs and situation, rather than target driven. The notion of responsible research is used to anchor the discussion. Conclusion Increasing the participation of people with dementia in research is a global priority. Nurses and nurse researchers play an important role in ensuring that people who take part in research have an optimal research experience. Implications for practice: Recruiting people with dementia to research studies is a national priority in many countries. With a greater understanding of the challenges involved and strategies that can be used to overcome them, nurses can have an effective role in the recruitment process and research experience.

Abstract
Alzheimer's disease (AD) research is at a critical time. The global society is increasingly aware of the frightening rate of growth of the human and financial burden caused by this condition and of the urgent need to halt its progression. Consequently, the scientific community holds great responsibility to quickly put in place and optimize the machinery necessary for testing new treatments or interventions. In this context demand for participants for AD research is at an all-time high. In this review, we will focus on a methodological factor that is increasingly recognized as a key factor that shapes trial populations and affects validity of results in clinical trials: patient engagement, recruitment, and retention. We outline specific problems relevant to patient engagement in AD including recruiting enough participants, difficulties in participant retention, ensuring the recruited sample is representative of the general AD population, the burden of screening failures, and new challenges related to recruiting in preclinical disease. To address the urgent need for more research studying the applicability and cost-effectiveness of different recruitment strategies across different settings and nationalities, we describe the Models of Patient Engagement for Alzheimer's Disease (MOPEAD) project, a public-private partnership promoted by the Innovative Medicine Initiative (IMI), which will provide a large multinational quantitative analysis comparing different innovative recruitment models. We also discuss strategies that address each problem and draw on the experience of Fundació ACE to argue that focusing resources on comprehensive AD centers that offer coordinated clinical and social care and participate in basic and clinical research, is an effective and efficient way of implementing many of the discussed strategies.

Abstract
BACKGROUND Few studies explore stroke survivor views and motivations towards stem cell therapy (SCT). This qualitative study explores the views and motivations of both stroke survivors and their partners/carers towards a proposed 2-arm Phase III Randomised Controlled Trial (RCT) comparing intracerebral insertion of stem cells with placebo neurosurgery in stroke survivors with disability. OBJECTIVE To explore views and motivations towards a proposed 2-arm stem cell trial and identify factors that may impede and enhance participation. DESIGN This study adopts a naturalistic design to explore the complexity of this field, employing a participatory action-research approach comprising a specialized Conversation (World) Café form of focus group. Data were collected via 5 Conversation Cafés with stroke survivors (age 40-75) and partners/carers between June and October 2016. Of 66 participants, 53 (31 male, 22 female) were stroke survivors and 13 (6 female, 7 male) were partners/carers. Qualitative data were analysed using a thematic approach. DISCUSSION AND CONCLUSION Stroke survivor views and motivations reflect anticipation of the personal and future benefits of regenerative medicine. Partners/carers sought to balance the value of stroke survivor hope with carrying the weight of hope as carer, a conflict burden adding to known caregiver burden. All participants expressed the need for during and post-trial psychological support. This study provides a rare opportunity to explore the prospective views and motivations of stroke survivors and their partners/carers towards a proposed Phase III 2-arm RCT. This adds weight to qualitative evidence exploring capacity, consent, decision making, perceptions of treatment risk and supports required for clinical trial participation.

Abstract
This research used the church as an exemplar to identify how community institutions provide opportunities for individuals living with dementia to continue living in meaningful ways. Study results from this exploratory study indicated churches are moving towards dementia-friendly spaces, but additional assistance is required. Namely, support with the costs of physical infrastructure improvements, dementia education, adequate transportation, and social supports were identified. Due to the significant presence that the church has in lives touched by dementia, policy that acknowledges its contributions to health would help to legitimize the church as a health resource and promote inclusive community culture for individuals in the context of dementia.

Abstract
Despite the importance and advantages of including people with dementia in research, there are various challenges for researchers and participants to their involvement. This article draws on the literature and experiences of a diverse group of authors, including a person with dementia, to provide recommendations about conducting research with people with dementia. Particular attention is given to in-depth interviews as a qualitative technique. More specifically, topics discussed include interview guide preparation, recruitment, obtaining consent/assent, conducting effective interviews, analysis and interpretation of data, effective communication of research findings, and reflections and recommendations for maintaining researcher and participant health. Given the current obstacles to participation in research of people with dementia, this is a timely article providing useful insights to promote improved outcomes using in-depth interviews.

Abstract
Alzheimer’s disease (AD) ranks as the 6th leading cause of death in the United States, yet unlike other diseases in this category, there are no disease-modifying medications for AD. Currently there is significant interest in exploring the benefits of pharmacological treatment before the onset of dementia (e.g., in those with mild cognitive impairment); however, recruitment for such studies is challenging. The current study examined interest in pharmacological intervention trials relative to other types of clinical interventions. A total of 67 non-demented older adults enrolled in a longitudinal cognitive aging study completed a questionnaire assessing interest in participating in a variety of hypothetical research study designs. Consistent with past research, results showed that the opportunities for participants to advance science, receive feedback about their current health, and help themselves or others, were associated with increased interest in clinical trial participation. Some factors were not associated with change in interest (e.g., a doctor not recommending participation) while others were associated with decreased interest (e.g., having to come in for multiple visits each week). Relative to other types of interventions, pharmacological intervention trials were associated with the least interest in participation, despite pharmacological interventions being rated as more likely to result in AD treatment. Decreased interest was not predicted by subjective memory concerns, number of current medications, cardiovascular risk, or beliefs about the likely success of pharmacological treatments. These results highlight the challenges faced by researchers investigating pharmacological treatments in non-demented older individuals, and suggest future research could contribute to more effective ways of recruiting participants in AD-related clinical trials.

Abstract
OBJECTIVE Older people from ethnic minorities are underrepresented in dementia care. Some of the determinants of access to care are knowledge and perceptions of dementia, which may vary between ethnic groups in the population. The aims of this study were to compare knowledge and perceptions of dementia and Alzheimer's disease (AD) among four ethnic groups in Copenhagen, Denmark, and to assess the influence of education and acculturation. METHODS Quantitative survey data from 260 participants were analyzed: 100 native Danish, and 47 Polish, 51 Turkish, and 62 Pakistani immigrants. Knowledge and perceptions of dementia and AD were assessed with the Dementia Knowledge Questionnaire (DKQ) supplemented with two questions from the Alzheimer's Disease Awareness Test (ADAT). Knowledge and perceptions of dementia and AD in the four groups were compared, and the influence of education and acculturation was assessed. RESULTS Group differences were found on the DKQ total score as well as all sub-domains. Turkish and Pakistani people were most likely to hold normalizing and stigmatizing views of AD. Level of education and acculturation had limited influence on dementia knowledge, accounting for 22% of the variance at most and had only minor influence on perceptions of AD. CONCLUSIONS Lacking knowledge and certain perceptions of dementia and AD may hamper access to services in some ethnic minority groups. Ongoing efforts to raise awareness that dementia and AD are not part of normal aging, particularly among Turkish and Pakistani communities, should be a high priority for educational outreach.

Abstract
OBJECTIVES The paper describes recruitment results and characteristics of the UP-TECH clinical trial sample, including level of care services use, informal caregiver burden and its determinants. METHODS UP-TECH is designed to test innovative care solutions for community-dwelling patients with moderate stage Alzheimer's disease and their caregivers in Italy. Four hundred and fifty patient-caregiver dyads were randomized into three arms receiving different combinations of services, composed of case management interventions, nurse visits, assistive technology and educational brochures. The research nurses administered a questionnaire comprising an in-depth socio-demographic assessment and several clinical scales, such as Novak's Caregiver Burden Inventory. Analyses of baseline data were conducted using uni- and bi-variate statistics. Linear regressions were computed to identify de-confounded correlates of caregiver burden. RESULTS Four hundred and thirty-eight patient-caregiver dyads were recruited and randomized. In our sample, patients are predominantly women (71.5%), with an average age of 81.5 years and a mean Mini-Mental State Examination score of 16.2. Caregivers are mostly women (66.2%) and offspring (55.7%), with a mean caregiver burden score of 27.6. They provide more than 50 hours of care per week, while receiving an almost negligible support from public services. Factors associated with caregiver burden are female gender, kinship and the patient's behavioral disturbances. The most important factor associated with lower burden is the employment of a live-in care worker. CONCLUSION The paper provides a comprehensive description of moderate stage Alzheimer's disease patients and their caregivers, suggesting useful markers of caregiver burden. The well-balanced randomization assures the reliability of the study data-set for prospective evaluation of care strategies.

Abstract
We share here our experience of recruiting pregnant women into an exercise intervention study. Recruitment challenges were anticipated owing to the study design, which required four hospital visits for cardiovascular assessment, a long-term (nine-month) commitment, and adherence to a 20-week exercise programme. Fifty-three women were assigned to one of three groups (no-exercise, land exercise or water exercise) using a 2 × 2 × 2 flexible randomisation design. Seven hundred forty-four women were screened at an antenatal clinic, of whom 501 were eligible to participate in the study. One hundred forty-five women were subsequently approached: 46 (32%) of whom agreed to participate, 42 (29%) were interested but then declined and 57 (39%) declined outright. Our study design helped recruit pregnant women as it allowed them some choice of group membership. We also noted that the participant-researcher relationship is important in reducing attrition. Our experience provides indications of likely recruitment and attrition rates for future randomised controlled trials of this type.

Degradation of misfolded proteins in neurodegenerative diseases: therapeutic targets and strategies. Exp Mol Med 2015; 47:e147.

Abstract
Mammalian cells remove misfolded proteins using various proteolytic systems, including the ubiquitin (Ub)-proteasome system (UPS), chaperone mediated autophagy (CMA) and macroautophagy. The majority of misfolded proteins are degraded by the UPS, in which Ub-conjugated substrates are deubiquitinated, unfolded and cleaved into small peptides when passing through the narrow chamber of the proteasome. The substrates that expose a specific degradation signal, the KFERQ sequence motif, can be delivered to and degraded in lysosomes via the CMA. Aggregation-prone substrates resistant to both the UPS and the CMA can be degraded by macroautophagy, in which cargoes are segregated into autophagosomes before degradation by lysosomal hydrolases. Although most misfolded and aggregated proteins in the human proteome can be degraded by cellular protein quality control, some native and mutant proteins prone to aggregation into β-sheet-enriched oligomers are resistant to all known proteolytic pathways and can thus grow into inclusion bodies or extracellular plaques. The accumulation of protease-resistant misfolded and aggregated proteins is a common mechanism underlying protein misfolding disorders, including neurodegenerative diseases such as Huntington's disease (HD), Alzheimer's disease (AD), Parkinson's disease (PD), prion diseases and Amyotrophic Lateral Sclerosis (ALS). In this review, we provide an overview of the proteolytic pathways in neurons, with an emphasis on the UPS, CMA and macroautophagy, and discuss the role of protein quality control in the degradation of pathogenic proteins in neurodegenerative diseases. Additionally, we examine existing putative therapeutic strategies to efficiently remove cytotoxic proteins from degenerating neurons.

Abstract
Alzheimer disease (AD) research faces challenges to successful enrollment, especially to clinical trials and biomarker studies. Failure to recruit the planned number of participants in a timely manner threatens the internal validity and success of clinical research, raising concerns about external validity and generalizability of results, and possibly leading to disparities in disease treatment. Methods to improve recruitment exist, but require varying levels of staff effort and financial resources, and evidence of effectiveness is often lacking or inconsistent. In this review, we summarize some of the available methods to improve AD research recruitment, the available literature to support or refute these strategies, and some of the experiences at the authors' AD Research Centers. We discuss the use of community-based participatory research principles and participant registries as a means to enhance research enrollment and increase diversity of research samples.

Abstract
BACKGROUND Study partners for dementia research participants are vital to the research process, but little is known about their role, responsibilities, and experiences. Study partners are usually family members or friends - often the patient's informal caregiver - who are knowledgeable about and usually accompany the participant to study visits. This study examines researchers' perspectives on the role of study partners in dementia research. METHODS Qualitative data collection and analytic methods were used. Semi-structured individual interviews with principal investigators, study coordinators, and research nurses (i.e. researchers; n = 17) at two academic research sites were recorded, transcribed, and content analyzed to identify themes in the data. RESULTS According to researchers, study partners either make or help make research enrollment and post-enrollment decisions, serve as knowledgeable informants for the participants, manage the logistics that enable participants to comply with a study's protocol, and provide comfort and encouragement for the patient to engage in and complete a study. Researchers describe ideal qualities of study partners as being able to provide reliable information, being dependable and adherent to the protocol, and not expecting a benefit. They also report that study partners may face both practical and emotional challenges during research participation. However, researchers believe that study partners derive dementia-related education, caregiver support, and satisfaction from their involvement in research. CONCLUSIONS Investigators, potential study partners, and institutional review boards should be aware of study partners' research responsibilities, challenges, and their interests as caregivers.

Abstract
BACKGROUND There is potential to increase the speed of scientific discovery and implement personalized health care by using digitized clinical data collected on the patient care experience. The use of these data in research raises concerns about the privacy and confidentiality of personal health information. This study explored community members' views on the secondary use of digitized clinical data to (1) recruit participants for clinical studies; (2) recruit family members of persons with an index condition for primary studies; and (3) conduct studies of information related to stored biospecimens. METHODS A qualitative descriptive design was used to examine the bioethical issues outlined from the perspective of urban-dwelling community members. Focus groups were used for data collection, and emergent content analysis was employed to organize and interpret the data. RESULTS Thirty community members attended one of four focus groups ranging in size from 4 to 11 participants. Five critical themes emerged from the focus-group material: (1) perceived motivators for research participation; (2) objective or "real-life" barriers to research participation; (3) a psychological component of uncertainty and mistrust; (4) preferred mechanisms for recruitment and participation; and (5) cultural characteristics that can impact understanding and willingness to engage in research. CONCLUSIONS The overriding concern of community members regarding research participation and/or secondary clinical and nonclinical use of digitized information was that their involvement would be safe and the outcome would be meaningful to them and to others. According to participants, biospecimens acquired during routine clinical visits or for research are no longer possessions of the participant. Although the loss of privacy was a concern for participants, they preferred that researchers access their personal health information using a digitized clinical file rather than through a paper-based medical record.

Abstract
OBJECTIVES The aim of this study was to evaluate the yield and cost of three recruitment strategies-direct mail, newspaper advertisements, and community outreach-for identifying and enrolling dementia caregivers into a randomized trial testing a nonpharmacologic approach to enhancing quality of life of patients and caregivers (dyads). METHOD Enrollment occurred between 2006 and 2008. The number of recruitment inquiries, number and race of enrollees, and costs for each recruitment strategy were recorded. RESULTS Of 284 inquiries, 237 (83%) dyads enrolled. Total cost for recruitment across methodologies was US$154 per dyad. Direct mailings resulted in the most enrollees (n = 135, 57%) and was the least costly method (US$63 per dyad) compared with newspaper ads (US$224 per dyad) and community outreach (US$350 per dyad). Although enrollees were predominately White, mailings yielded the highest number of non-Whites (n = 37). DISCUSSION Direct mailings was the most effective and least costly method for enrolling dyads in a nonpharmacologic dementia trial.

Abstract
PURPOSE The purpose of the study was to investigate how retention strategies employed by the Diabetes Empowerment Program (DEP) contributed to retention. METHODS An experienced moderator conducted in-depth interviews (n = 7) and 4 focus groups (n = 29) with former DEP participants. Interviews were recorded, transcribed, and coded using iteratively modified coding guidelines. Results were analyzed using Atlas.ti 4.2 software. RESULTS Participants were African American and predominantly female, low income, and with more than 1 diabetes complication. Key retention themes included: (1) educator characteristics and interpersonal skills ("The warmth of the staff . . . kept me coming back for more."), (2) accessible information ("I didn't know anything about diabetes [before]. I was just given the medicine."), (3) social support ("I realized I wasn't the only one who has diabetes."), (4) the use of narrative ("It's enlightening to talk about [my diabetes]."), and (5) the African American helping tradition ("I went not just for myself but for my husband."). CONCLUSIONS While many interventions focus on costly logistics and incentives to retain at-risk participants, study findings suggest that utilizing culturally tailored curricula and emphasizing interpersonal skills and social support may be more effective strategies to retain low-income African Americans in diabetes education programs.

Abstract
The growing importance of involving volunteers and the wider community in research is well recognized. Participants are no longer mere “subjects” but are active partners in the research process, and for these engagements to be successful, effective communication is vital. Researchers are well practiced at disseminating their findings to the wider scientific community, but what are the gold standards when disclosing results, both individual and aggregate, to study participants? Shalowitz and Miller (2008a) emphasize the need to offer research results as an “appropriate and obligatory expression of respect for persons,” and the implications of receiving results have been widely examined (Shalowitz and Miller, 2008b; Fernandez et al., 2004). Despite the interest in this area, however, very few studies have looked at dementia research and how best to convey study information and results to participants so as to maximize their involvement and ownership of research. In an attempt to address this gap in the evidence base, we undertook an audit of the views concerning a study newsletter, which had been designed to provide some feedback to those volunteering for the research.

Abstract
BACKGROUND Connecting willing patients with dementia to suitable clinical research studies has been historically challenging. The United Kingdom Dementia and Neurodegenerative Research Network (DeNDRoN) was established to link patients into high-quality studies. One component is DemReg, a register of dementia patients and their carers who have agreed to be approached regarding future research studies. The limited literature highlights the predominance of altruism mediating research register participation. The objective of this study was to understand the motivations of patients and carers to participate in DemReg. METHODS There were 107 participants in the study, interviewed using a questionnaire to determine which factors were important in their decision to be on the register. The study compared the proportion of the altruistic motivations articulated with the proportion of the other answers offered. RESULTS The two most important motivators for registering on DemReg were to help others (44%; p < 0.001) or themselves (29%; p < 0.001) and altruistic motives took precedence over those for personal benefit. Participants were not motivated by the prospect of payment or by concern that they would be letting down their clinician if they did not register. CONCLUSIONS There are currently major projects within the United Kingdom to increase the number of patients on dementia registers and to further involvement in dementia research. This study, to the best of our knowledge, is the first to assess the motivations of patients and carers for joining a dementia research register in the United Kingdom, and the findings highlight the importance of altruistic motives.

Abstract
BACKGROUND Treatment disparities in Alzheimer's disease (AD) have received little attention. Determining whether disparities exist in this subpopulation is an important health policy issue. OBJECTIVE The aim was to determine whether an association existed between race/ethnicity and exposure to AD pharmacotherapy across 4 state Medicaid populations. METHODS Data from the Centers for Medicare and Medicaid Services (CMS) were used in this retrospective study. Persons with AD enrolled in California, Florida, New Jersey, or New York Medicaid programs on January 1, 2004, and remained in that program for 1 year. Individuals had an AD diagnosis based on the ICD-9-CM code 331.0. Outcomes of interest were exposure to a cholinesterase inhibitor (ChEI) or memantine. Multivariate logistic regression was used to test for the association between race/ethnicity and exposure to a ChEI or memantine. Variables of interest included demographic characteristics and resource utilization factors. The Oaxaca-Blinder decomposition method was used to test for disparities to determine whether exposure to AD pharmacotherapy was influenced by race. RESULTS Race, age, long-term care admittance, inpatient care admittance, state of residence, and sex were significant predictors of AD pharmacotherapy exposure (P < 0.0001 for all variables). Racial/ethnic disparities were observed with respect to exposure to a ChEI or memantine between non-Hispanic whites and Hispanics (in favor of Hispanics) in Florida (P < 0.0001), between non-Hispanic blacks and Hispanics (in favor of Hispanics) in California (P < 0.0001) and Florida (P < 0.0001), between non-Hispanic blacks and non-Hispanic others (in favor of non-Hispanic others) in California (P < 0.0001) and New York (P < 0.0001), and between Hispanics and non-Hispanic others (in favor of non-Hispanic others) in California (P = 0.001) and New York (P < 0.0001). CONCLUSIONS Disparities in AD pharmacotherapy exposure among minority populations are just as prevalent, if not of greater magnitude, than minority/white disparities.

Abstract
Despite the importance of movement and activity indicators in predicting the risk of falls in older adults, collection and analysis of such data are limited. The dearth may result from recruitment challenges faced by fall-related studies that capture data on movement and activity in older adults. This article addresses recruitment and sampling methodology issues and draws attention to the gap in best practices left by previous literature. Authors conducted a systematic review of methods used to recruit elderly individuals for "activity-related fall studies" that assessed subjects' movement and mobility, and investigated incidence of real falls. The review highlighted effective recruitment strategies and identified challenges across several settings. Literature review findings were compared to recruitment challenges encountered in an activity-related fall study from 2011, focused on enrolling a target group of older adults with both high risk of falling and the requisite cognitive capacity to adhere to activity protocols. The analysis yielded several recommendations for improving recruitment of older adults for activity-related fall studies, including: recruiting from community-based settings; utilizing short-term activity protocols to promote involvement among institutionalized elderly; establishing eligibility criteria that may include those with lower cognitive functioning, mobility restrictions, and co-morbidities; employing direct-mail recruitment methods; and utilizing intermediaries to recruit institutionalized elderly.

Abstract
This article describes ethical, legal and professional components of the two core requirements of clinical research: informed consent and risk-benefit relationships.

Abstract
African Americans experience a greater risk of Alzheimer disease (AD), but are underrepresented in AD research. Our study examined barriers and facilitators of AD research participation among African Americans. Investigators conducted 11 focus groups with African American participants (n=70) who discussed barriers and facilitators to AD research participation including lumbar puncture studies. The moderator and comoderator independently reviewed the transcripts, identified themes, and coded transcripts for analysis. Participants were predominately female (73%) with a mean age of 52 years (range 21 to 86 y). Concerns and attitudes were consistent across education, socioeconomic status, and sex. Mistrust was a fundamental reason for nonparticipation. Additional barriers included insufficient information dissemination in the African American community, inconvenience, and reputation of the researcher and research institution. Barriers to participation in AD biomarker studies were fear of the unknown and adverse effects. Altruism and relevance of research projects to the individual, family members, or the African American community facilitate participation. Increased participation results from relationships with the community that extend beyond immediate research interests, dissemination of research findings, and emphasis on relevance of proposed studies. Pervasive barriers impede African American participation in AD research but can be overcome through a sustained presence in the community.

Hensel DJ, Fortenberry JD, Harezlak J, Craig D. The feasibility of cell phone based electronic diaries for STI/HIV research. BMC Med Res Methodol 2012; 12:75.

Abstract
BACKGROUND Self-reports of sensitive, socially stigmatized or illegal behavior are common in STI/HIV research, but can raise challenges in terms of data reliability and validity. The use of electronic data collection tools, including ecological momentary assessment (EMA), can increase the accuracy of this information by allowing a participant to self-administer a survey or diary entry, in their own environment, as close to the occurrence of the behavior as possible. In this paper, we evaluate the feasibility of using cell phone-based EMA as a tool for understanding sexual risk and STI among adult men and women. METHODS As part of a larger prospective clinical study on sexual risk behavior and incident STI in clinically recruited adult men and women, using study-provided cell phones, participants (N = 243) completed thrice-daily EMA diaries monitoring individual and partner-specific emotional attributes, non-sexual activities, non-coital or coital sexual behaviors, and contraceptive behaviors. Using these data, we assess feasibility in terms of participant compliance, behavior reactivity, general method acceptability and method efficacy for capturing behaviors. RESULTS Participants were highly compliant with diary entry protocol and schedule: over the entire 12 study weeks, participants submitted 89.7% (54,914/61,236) of the expected diary entries, with an average of 18.86 of the 21 expected diaries (85.7%) each week. Submission did not differ substantially across gender, race/ethnicity and baseline sexually transmitted infection status. A sufficient volume and range of sexual behaviors were captured, with reporting trends in different legal and illegal behaviors showing small variation over time. Participants found the methodology to be acceptable, enjoyed and felt comfortable participating in the study. CONCLUSION Achieving the correct medium of data collection can drastically improve, or degrade, the timeliness and quality of an individual's self-reported sexual risk behavior, which in turn, is a key factor in the success of intervention or education programs relying on this information. Our findings demonstrate that completion of electronic diaries via cellular phone is feasible way to describe STI/HIV risk among clinically recruited adult men and women.

Abstract
SUMMARY Many clinical trials for Alzheimer’s disease and related disorders struggle to achieve enrollment goals, hampering the progress of research. To help address this problem, the Alzheimer’s Association® has developed and implemented a new clinical trial-matching service designed to increase awareness of ongoing clinical trials among potential participants, improve initial matching of potential participants to enrollment criteria and thus help investigators achieve enrollment goals. This service, Alzheimer’s Association TrialMatch™, uses numerous personal and disease characteristics to match users with potential clinical trials that are currently enrolling participants. It provides users with direct access to trained professional consultants who interpret and explain an individual’s eligibility for specific clinical trials and is designed for use by patients, caregivers, healthy volunteers, physicians and other healthcare providers and researchers. During the first year of operation (July 2010–June 2011), the service received almost 45,000 queries and more than 11,000 completed profiles, which led to 2784 referrals to clinical trials. At least 163 participants of the service are known to have enrolled in a clinical trial. Participants self-report their enrollment into trials.

Abstract
BACKGROUND The identification and enlistment of suitable participants into clinical studies is often challenging, requiring a large commitment of time and staff resources. The recruitment and retention of populations typically underrepresented in research present additional challenges to enrollment of sufficient numbers of participants in clinical studies. Inadequate participation may undermine the pace and direction of new treatment discoveries. PURPOSE Registries of potential research participants are powerful tools to support research by providing a framework to streamline screening and recruitment and to maintain a communication history with potential research participants. The authors present a model for the development and implementation of a web-based database system to support recruitment, enrollment, and retention of potential study participants in close alignment with the goals of the Wisconsin Alzheimer's Disease Research Center (ADRC). METHODS The required data elements and major information domains for the registry were identified using a structured problem-solving and system design approach and the collaboration of a multidisciplinary team of stakeholders. The system performance, utility, and usability were assessed through multiple iterations with the users. RESULTS The process-oriented approach culminated in a multifaceted tool that combined contact management and potential research participant registration to assist with the challenges of recruitment and retention in clinical research. A unique feature of the registry design model was its contact management capabilities for efficient tracking of all contacts with registrants. LIMITATIONS We have focused on the development and implementation of a system for the recruitment of older adults with specific cognitive and medical characteristics. However, our procedures for identifying data needs and database system utility and functionality can be transferred easily to other populations and settings. As with any multipurpose registry database system, careful management and training are essential to optimize efficiency. CONCLUSION Adding a contact management element to the registry design significantly improved the efficiency of communication between clinical study coordinators and potential research participants, as well as the communication among coordinators.

Abstract
This manuscript focuses on qualitative data collected for AAKOMA Project, a 2-phase treatment engagement intervention trial for depressed African American adolescents and families. Data are presented from our phase I study of adult perspectives on African American adolescent depression, depression treatment, and research engagement. The research team conducted four focus groups (N = 24) and generated major themes from the data including ideas regarding the manifestations of depression in African American youth and psychosocial barriers to participation in depression research and treatment. Findings indicate that success in recruiting and retaining African American youth in depression research and treatment may include using innovative means to overcome the culturally embedded attributions of depression to non-biological causes, beliefs about the cultural insensitivity of treatments and challenges in the logistics of obtaining care. Adults report that encouraging youth and familial involvement in treatments and research should include targeted, community-partnered activities involving diverse staff in leadership roles and including community members as equal partners.

Abstract
In light of our limited understanding of what motivates older adults to participate in clinical studies of Alzheimer's disease (AD), the current study examines incentives and barriers to participating in AD clinical research among older adults. 235 participants enrolled in the Boston University Alzheimer's Disease Center research registry (75 ± 8 years, range 58-99 years, 60% female), a longitudinal registry from which individuals are recruited into other clinical studies, completed a survey assessing registry participation satisfaction, religiousness, trust in healthcare institutions, and medical research attitudes. Most participants reported initially enrolling in the registry for societal benefit. Insufficient time was a commonly endorsed barrier to enrolling in other Center-approved studies, particularly among younger participants. Driving and a lack of transportation to the medical facility were also barriers, particularly for older participants. Transportation was the most popular incentive, followed by home-based visits (particularly for older participants and participants with less formal education) and compensation (particularly among respondents from racial/ethnic minority groups). Participation interest in other studies was associated with favorable medical research attitudes (r = 0.34, p = 0.00003) but not religiousness (r = -0.09, p = 0.21), or trust in healthcare institutions (r = 0.09, p = 0.17). Among older adults, societal benefit is a motivating factor for registry enrollment; however, participation in additional studies is hindered by insufficient time among younger participants and transportation barriers among older participants. Providing transportation, home-based visits, and modest compensation may improve participation rates. Furthermore, favorable attitudes toward medical research are strongly associated with interest in enrolling in additional studies and may serve as a beneficial outreach triage technique.

Abstract
Debate exists regarding differences in the prevalence of Alzheimer disease (AD) in African Americans and Hispanics in the United States, with some evidence suggesting that the prevalence of AD may be considerably higher in these groups than in non-Hispanic whites. Despite this possible disparity, patients of minority ethnoracial groups often receive delayed diagnosis or inadequate treatment for dementia. This review investigates these disparities by conceptualizing the dementia disease process as a product of both biological and cultural factors. Ethnoracial differences in biological risk factors, such as genetics and cardiovascular disease, may help to explain disparities in the incidence and prevalence of AD, whereas race-specific cultural factors may impact diagnosis and treatment. Cultural factors include differences in perceptions about what is normal aging and what is not, lack of adequate access to medical care, and issues of trust between minority groups and the medical establishment. The diagnosis of AD in diverse populations may also be complicated by racial biases inherent in cognitive screening tools widely used by clinicians, but controlling for literacy level or using savings scores in psychometric analyses has the potential to mitigate these biases. We also suggest that emerging biomarker-based diagnostic tools may be useful in further characterizing diverse populations with AD. Recognizing the gap in communication that exists between minority communities and the medical research community, we propose that education and outreach are a critical next step in the effort to understand AD as it relates to diverse populations.

Abstract
Ethical core issues in research with human subjects are related to informed consent and risk-benefit assessment. This is valid for all types of studies. However, there has been much greater focus of ethical considerations on controlled clinical trials than on naturalistic trials, probably because the former are interventional in nature and may have unknown and perhaps severe somatic risks, whereas naturalistic studies seem not to intervene but only to observe, and therefore are assumed to have fewer or almost no risks. However, there are also ethical implications in naturalistic trials, although their weight is differently accentuated, more with potential, more with potential psychological burdens of the observational procedures and more with potential physical risks in interventional trials. This will be elaborated with examples of placebo-controlled trials and of incidental findings in screenings, of marketing influences on observational studies, and of psychological burdens by survey interviews. The ethical implications will be analyzed within a more general framework. Finally, recommendations will be offered.

Abstract
Genetic susceptibility testing for common diseases is expanding, but little is known about race group differences in test perceptions. The purpose of this study was to examine differences between African Americans and Whites in knowledge, attitudes, and motivations regarding genetic susceptibility testing for Alzheimer's disease (AD). Before enrolling in an AD genetic testing research trial, 313 first-degree relatives of AD patients (20% African American; 71% female; mean age = 58 years) were surveyed regarding: (1) knowledge about genetics and AD risk; (2) concerns about developing AD; and (3) reasons for seeking testing. In comparison to Whites, African Americans were less knowledgeable about genetics and AD risk (p < .01) and less concerned about developing AD (p < .05), with lower levels of perceived disease risk (p = .04). The results suggest that African Americans and Whites differ notably in their knowledge, beliefs, and attitudes regarding genetic testing for AD. Additional research with more representative samples is needed to better understand these differences.

Abstract
This study examines how underrepresented older urban and rural-dwelling individuals conceptualize participation in cognitive impairment studies. Nine focus groups were held with urban and rural-dwelling older adults who had participated in a community-based memory screening study. Expected and experienced benefits of research participation were motivators for study participation in all focus groups. Results indicate that participation in memory research was believed to lead to an understanding of memory function. Focus group participants expressed an active interest in research on dementia, and viewed research participation as a way to address memory concerns and provide a benefit to society.

Abstract
We describe the history, development, and success of the recruitment and screening procedures used by researchers at the University of California, Davis Alzheimer's Disease Center (UCD ADC) to facilitate minority enrollment in research. After an initial, unsuccessful approach with satellite clinics in minority neighborhoods, the ADC shifted to an active community outreach approach. Multiple strategies were implemented to remove barriers to research participation such as providing transportation to clinical appointments and offering in-home cognitive screening. Considerable resources were directed toward hiring and training bicultural and bilingual individuals with knowledge of the target populations, both as recruiters and staff involved in clinical assessment. Implementation of these methods resulted in a dramatic increase in the number of ethnic minorities enrolled (and retained) in research protocols, including protocols that are complex and longitudinal. Diversity was achieved on other variables as well; years of education in the cohort range from 0 to 21, with 26% having 8 years or less. The community screen identified candidates for an in depth clinical evaluation and enrollment in longitudinal research, and we examined factors that predicted a positive response to invitation for the clinical evaluation. Individuals with a broader fund of knowledge were more likely to participate independent of other variables including ethnicity and education. When diversity is an important goal active outreach is far more efficacious than clinic-based and advertising-based approaches to recruitment.
