Running Head: SYSTEMATIC REVIEW: CAREGIVER EDUCATION Systematic Review: Caregiver Education for Improved Quality of Life for Clients with Alzheimer’s and Related Dementia’s Rosario Alvarez, Regina Eason, Comfort Orji, and Enrique Rivera Touro University Nevada 1 SYSTEMATIC REVIEW: CAREGIVER EDUCATION 2 Systematic Review: Caregiver Education for Improved Quality of Life for Client's with Alzheimer’s Introduction Have you ever forgotten an item in the home, experienced trouble recalling certain events, or remembering the name of someone you once remembered in the past? The societal norm for an explanation of memory loss is that it’s due to the normal part of aging. Furthermore, throughout society there have been many misconceptions of Alzheimer’s disease, but there is a significant decline in awareness of it being a serious medical condition. The truth is that dementia is a progressive disease that impacts many individuals 65 years or older. As Doble (2009) state, “Dementia is not an inevitable part of normal aging nor is memory loss always the first sign of dementia.” Therefore, there are many different cases of dementia and the most common form of dementia is Alzheimer’s disease. The main diagnosis of clients with dementia is the inability to perform meaningful everyday occupations due to cognitive impairments. Health professionals have a major impact on the clients with dementia. As a healthcare professional, it is our duty to have a better understanding of the medical condition and provide adequate care for the client and caregiver. The occupational therapist role with the client with dementia is to be supportive, provide sufficient information to the caregiver, and evaluate the effectiveness of the intervention. The purpose of providing the information to the caregiver is to let them have a better understanding of what is to come with the progression of the condition. The interventions are client-centered and focus on how to maintain the client’s self-care activities of daily living (ADL) despite a decline in health. SYSTEMATIC REVIEW: CAREGIVER EDUCATION 3 Organization In this section, we will discuss the findings of the literature review. Definitions of the constructs will be provided followed by an introduction of the study. Next, we will explain the purpose of the study, the theoretical findings from the research, position of the hypotheses, and provide an overview of existing theories within the study. Finally, a brief summary on how the topic is pertinent to our research and suggestions for future research. How the Literature was Found In the literature review process, research articles were found using the Touro library system which holds a large amount of databases for conducting research. The Medline (EBSCO) search engine was used most frequently during the review of literature. The American Occupational Therapy Journal (AJOT) was another powerful tool that members of this research team used to gain a perspective of what type of studies are being conducted, and to identify research that needs to be done. When using the Touro library system, key phrases from the research question were used such as: “caregiver education for clients with dementia”, and “improving quality of life (QOL) for individuals with dementia.” All members of the research team conducted their own research using methods agreed upon beforehand for inclusion and exclusion criteria. One of the inclusion criteria was that all the research articles must be recent, with no more than 12 years of elapsed time from date of publication until present. Other reasons for exclusion were due to lack of clarity, inferences could not be made towards the original research question, or the information contained in the articles was not relevant.

Purpose of Study The purpose of this study is to bring various articles together to bridge the gap between caregiver education and translating that into an improved QOL for the individual with Alzheimer’s disease. In the literature, research on the topic of caregiver education to improve QOL for the person being cared for is vague and only briefly discusses the topic without any significant depth, which is why this review hopes to clarify and refine this topic. However, one SYSTEMATIC REVIEW: CAREGIVER EDUCATION 5 can infer from the research studies that one of the main objectives is to ultimately improve the QOL of the caregiver so it can translate to the person being cared for. For the most part, quantitative studies which measure a specific intervention such as: Martin-Carrasco and colleagues (2009) who introduced a psychoeducational program to reduce the caregiver burden, and Neely, Vikstrom, and Josephsson (2009), who measured a memory intervention in dementia, was the most common type of research material found. Main Research Question/Objective The research question is as follows: Does occupational therapy education to caregivers improve the QOL for clients diagnosed with Alzheimer’s disease and related dementias? Reasons why Research Question is Important Theoretical reason. In any professional field, the requirement of research is essential to keep the profession viable and moving with the current state of the world. To guide practice, theory is fundamental in making the profession credible, reliable, and relevant. Theory also helps organize “information into a coherent body, explain events that have occurred, and predict events that may happen” (Salkind, 2009, p. 3). Moreover, theory is the foundation to research and is used readily in occupational therapy (OT). A popular theory within OT is the Person-Environment-Occupation theoretical model (PEO), which helps to explain and bring together the role “uplifts” can play in the “transactional relationship between caregivers and care recipients, their occupations, and environments” (Donavan & Corcoran, 2010, p. 591). In much the same way, this study is bringing compiled data to tie ideas together to show in an expository fashion if caregiver education improves the QOL of individuals with Alzheimer’s. SYSTEMATIC REVIEW: CAREGIVER EDUCATION 6 Practical reasons. Because this study is novel in the way it looks specifically at caregiver education to improve QOL for care recipients, it will give practicing therapist, students, and populations of interest a better understanding of the dynamic that is involved in translating education to improved QOL. Thus, weaving this concept into future interventions will help expand knowledge and provide better care for individuals not only with an Alzheimer’s diagnosis, but for anyone that needs caregiver services. Hypotheses What Do You Hope to Find From this Literature? From the literature we hope to find information that is related to the research question in order to deduce that caregiver education does positively affect the QOL of the care recipient, and in this particular literature review, individuals with Alzheimer’s disease. It is essential not to look for a verbatim answer to our research question, but rather to get a general idea of where the research is leading, and then make inferences based on the data. The PEOP model was one of the theoretical frameworks used to guide the hypotheses of this literature review. The PEOP model uses the context of the individual to affect their occupational performance/output, in much the same way, the people involved in the individual’s context can either work to benefit or negatively affect occupational performance. Therefore, caregiver education through occupational therapy can be used to benefit the client because caregiver’s are directly associated with the client’s immediate environment. MOHO is another widely used theoretical model in occupational therapy, that helps the therapist better understand the dysfunction of the client to develop interventions that incorporate the individual’s motivation, performance capacity, and any environmental barriers (Kielhofner et SYSTEMATIC REVIEW: CAREGIVER EDUCATION 7 al., 2009). For this literature review, MOHO helps guide our hypothesis to infer that by thoroughly educating caregiver’s on proper ways to care for care recipient’s, they will improve their own QOL, as well as, the QOL of the person they are caring for. Operational Definitions of Constructs Name of Construct(s) Dementia Operational Definition “Deterioration in cognitive functioning that renders a person unable to meet the diverse intellectual demands of everyday life (Doble, 2009, p. 216).” “Often manifest bizarre behaviors or inappropriate behavior. Inability to make necessary association without the appropriate stimulus of an object before them. Frequently confused with memories of the past (Lewis, 2003, p. 137).” Caregiver Role “Fill the role of collaboration in the intervention with Dementia & process of the client, identify barriers and support for Caregiver occupational participation, adapt the environment, Education adjust activity demands, and guide compensatory strategies.” The caregiver education includes education about dementia, strategies to adapt activities or compensate for declining performance in areas of occupation of the client (Brown & Stoffel, 2011, p. 235).” Occupational “Identify an individual’s occupational performance Therapy Role with baseline. Elicit specific information about the Clients with individual’s premorbid levels of occupational and social Dementia functioning from the individual and other relevant informants (Doble, 2009, p. 227).” Intervention “Occupational therapists evaluate physical, sensoryStrategies Useful perceptual, cognitive, psychosocial, ADLs, and with Dementia pertinent information from family to determine client’s Clients functional level. Recommend activities such as counseling, relaxation techniques, compensate for functional deficits by rearranging the environment and the use of adaptive equipment for self-care activities if necessary (Lewis, 2003, p. 143).” QOL of the QOL is the personal context of satisfaction within your Caregiver & Client environment. The caregiver of the client with dementia with Dementia generally their QOL is affected due to the condition of the client. Reference Doble (2009) Lewis (2003) Brown & Stoffel (2011) Doble (2009) Lewis (2003) SYSTEMATIC REVIEW: CAREGIVER EDUCATION 8 Synthesis and State of the Literature We found that the literature addressing educating the caregiver to promote QOL in a client with dementia is mostly agreeable. Most of the literature agrees that the QOL of the caregiver is related to the QOL of the client (Dooley & Hinojosa, 2004). OT interventions including home evaluations, home assessments that include activities of daily living and instrumental activities of daily living, recommendations, and tailored activity prescriptions promoted client abilities and reduce behavioral disturbances as well as improved the QOL and general health status for both client and caregiver (Hasselkus & Murray, 2007, Letts et al., 2011). In the study, the interventions are done in conjunction with the caregiver and OT, to promote caregiver education and improve client satisfaction with activity engagement, as well as assisting caregivers with the occupational demands of the caregiving responsibilities to retain a sense of unity and purpose (Hasselkus & Murray, 2007, Letts et al., 2011). Adherence to the OT recommendation produced improvements in QOL for client and lowered the burden felt by the caregiver (Dooley & Hinojosa, 2004, Letts et al., 2011). Educating the caregiver on providing certain care was also beneficial. Researcher found that educating the caregiver on using flexible and collaborative approaches such as using cognitive dementia rehabilitation and implementing the knowledge gained on how other caregivers optimize uplifts was associated with caregiver well-being and enhanced treatment outcomes that benefited the client (Dooley & Hinojosa, 2004; Donovan & Corcoran, 2010; Neely, Vikstrom, & Josephsson, 2009). Another factor of consensus on improving the QOL of clients with dementia is to provide the family, caregivers and client, with a Pyschoeducational Intervention Program (PIP) and/or a multicomponent intervention including support groups, tailored counseling, and education SYSTEMATIC REVIEW: CAREGIVER EDUCATION 9 simultaneously. This led to statistically significant improvements in QOL for caregivers by decreasing caregiver burden, and improved the life of the client by helping the client stay home longer, be with peers, support their self-esteem, and improve their coping skills (Belle et al., 2006; Black et al., 2010; Martin-Carraasco et al. 2008; Sorensen, Waldorff, & Waldemar, 2008). A study that did not find similar results with counseling found that an intervention consisting solely of structured family meetings did not reduce caregiver burden of their health related QOL and did not prevent depression or anxiety disorders (Joling et al., 2012). Main Findings/Conclusions/Discussion Source Banerjee et al. (2009) Belle et al. (2006) Black et al. (2009) Summary Developed Stroud/ADI Dementia Quality Framework, a cross national population framework for assessing QOL, impact of services and policies on people with dementia and their caregivers. Tested the effects of a structured multicomponent intervention on QOL and clinical depression in caregivers of people with dementia. Also tested rates of institutional placement of care recipients in 3 diverse racial groups. Investigated the social, physical, psychosocial, and financial impact of dementiarelated conditions on caregivers’ QOL. Main Findings The Stroud/ADI Dementia Quality Framework: Enables broader societal and personal elements of QOL to be included in analysis Helps evaluate programs, policies and services Validity across cultures A structured multicomponent intervention adapted to individual risk profiles can increase the QOL of ethnically diverse dementia caregivers. Providing adequate and accessible support systems and appropriate interventions to caregivers has the potential to alleviate this burden ensuring that patients can remain in the community longer and ease the burden of the caregiver and demands on the health care system.

Studies the effectiveness of occupational therapy intervention to promote health, QOL, and client and caregiver satisfaction. Walking is a feasible, sustainable and cost effective way of exercising. Dynamic walking may encourage not just physical activity but psychosocial support from the caregiver as well. Optimizing uplifts is associated with caregiver wellbeing and enhanced treatment outcomes. OTs have the unique expertise to help caregivers develop and modify daily tasks to emphasize the positive aspects of care and in doing so promote occupational performance of the caregiver and client. Adherence to OT recommendations derived from individualized assessments produced significant improvements in QOL for client and lowered the burden felt by caregiver. Community-based interventions reported significantly better QOL and general health status for both client and caregiver. Home assessments followed by written recommendations and follow-up visits found significant group effects. Tailored activities reduced behavioral disturbances and caregiver burden while improving client activity engagement. Environmental and compensatory strategies appeared to improve health SYSTEMATIC REVIEW: CAREGIVER EDUCATION 11 and QOL for both client and caregiver. Martin-Carrasco et al. (2009) Evaluated the benefits of a Psychoeducational Intervention Program (PIP) on caregiver burden. Neely, Vikstrom, & Josehsson (2009) Sorenson, Waldorff, & Waldemar (2008) Examined the effectiveness of a collaborative memory intervention for persons with dementia and their spousal caregivers. Identified and analyzed an intensive structured psychosocial intervention program with tailored counseling, education, and support groups for home-living patients with Alzheimer’s disease and their spousal caregivers. Psychosocial training of caregivers can minimize caregiver distress and help them develop problem-solving strategies. The results support the efficacy of a PIP in reducing levels of burden experienced by caregivers and the results also support a reduction in burden improves QOL and perceived health for both client and caregiver. The active participation of the caregiver mattered in cognitive dementia rehabilitation. Caregivers working together with their spouse can use acquired knowledge in a new context and their spouse with dementia can benefit from this. Caregivers were able to cope better with the challenges their partner’s disease involved, and they were able to face everyday life and social relations with more serenity and competence. Clients found the intervention supported their self-esteem, and supported them in coping with challenges of managing everyday life and social relations. Main Findings of Review Research demonstrated that clients with dementia require a safe and supportive environment, prescribed activities to maintain function, modifications to home and activities, and could also benefit from simple exercise such as walking. These interventions in turn provide the SYSTEMATIC REVIEW: CAREGIVER EDUCATION 12 client with dementia and the caregiver a better QOL and are all interventions that an occupational therapist could provide. Inferences/Conclusions from the Literature Within the literature much of the research has concluded that family caregiving for clients with dementia can be somewhat of a challenge. The family caregiver plays a major role for the client with dementia and impacts the QOL within the environment. According to Belle and colleagues (2006), they tested the effects of multicomponent interventions on QOL and clinical depression in caregivers with three diverse racial groups. They concluded that the rate of clinical depression among caregivers in the intervention group was statistically significantly lower than that of the control group. Furthermore, the research suggested that minimal support and attention may have positive effects on caregivers. However, when reviewing some of the research it also suggested that with the help of a support system, maintaining a safe environment, home modifications, and providing interventions for the client with dementia, lessened the burden of the caregiver and improved their QOL. According to Sorenson and colleagues (2008), the research concluded that the individual experiences of a caregiver of a client with dementia have similar challenges. If the caregivers are provided with psychological counseling along with being involved in a support group, they are most likely to better cope within their environment. Therefore, the QOL will improve significantly for caregiver and client with dementia. One study recommended occupational therapy services be provided to the client with dementia and the caregiver, so that there will be a significant improvement in the QOL for both (Dooley & Hinojosa, 2004). According to Dooley & Hinojosa (2004), the research concluded that the unique value of occupational therapy services for client with dementia and the caregiver will be beneficial in their overall QOL. SYSTEMATIC REVIEW: CAREGIVER EDUCATION 13 Findings in Light of Research Objective Based on the review of literature, it is evident that the topic of caregiver education is a fundamental component in providing QOL to the care recipient. In light of this finding, the research also points to the positive and negative effects a caregiver can have on the individuals they care for based on their own QOL. As emphasized by Dolley and Hinojosa (2004), QOL for the caregiver is closely tied with QOL to the care recipient. Not only does a positive QOL for the caregiver translate into how positive the recipient’s perception of QOL will be, but also the negative aspect of QOL, such as burden and depression which is closely related to how negative the client’s QOL is. This is where an intervention designed to educate caregiver’s on the cause and effect relationship they have on the overall QOL for the people they care for would be very helpful in reducing the negative qualifiers of QOL that affect both parties. In the literature a direct correlation with caregivers and the susceptibility of developing depression due to the occupation of providing care to persons with Alzheimer’s and related dementia's was discussed (Black et al., 2009; Dooley & Hinojosa, 2004, Belle et al. 2006). Therefore, from the aforementioned study, it is clear that if a negative qualifier such as depression is felt by the caregiver, the care recipient will experience a negative qualifier as well, or a reduction in QOL due to the QOL experienced by their caregiver. Not only was depression a common theme throughout this review, but also: emotional burden, helplessness, and stress which all tend to affect the caregiver in negative way. It is clear that education is a strong intervention strategy that not only helps improve QOL for everyone involved in the caretaker process, but it also transcends the classic definition of QOL to a more personal and global one that involves: independence; enjoyment of daily SYSTEMATIC REVIEW: CAREGIVER EDUCATION 14 activities; maintaining identity; respect; spirituality; communication; love; and the ability keep relationships. As of 2010, 9.9 million Americans provide “unpaid caregiving” for people with Alzheimer’s and dementias (Donavan & Corcoran, 2010, p. 590) translating to the majority of the people providing care as the family members themselves. This could be an indicator as to why there is so much emotional distress associated with caring for an individual with Alzheimer or related dementia's, because of the emotional attachment component involved and further research would need to be conducted to understand this phenomenon better. Gaps in the Literature and Suggestion Areas for Future Research Based on this literature review gaps in the literature include a need for more research in: Multicomponent interventions with an eye on effectiveness at the community level (Belle et al., 2006) The use of modern, universal frameworks of quality of life impact on population (Banerjee et al., 2012) The effect of community accessible support and interventions on caregiver skill as well as healthcare system burden ( Black, 2012; Dooley, 2004) The relationship between caregiver wellness and positive approaches to caregiving (Donovan & Corcoran, 2010) Links between client quality of life and psychosocial influence as well as effective interventions for the promotion of continued social participation (Cerga-Pashoja, 2010; Letts, 2011; Neely, 2009; Sorenson, 2008) Effectiveness of spousal collaboration (Neely et al., 2009) SYSTEMATIC REVIEW: CAREGIVER EDUCATION 15 Also, in searching for literature to answer the question posed by this literature review, it seems that more research may be beneficial in directly testing if occupational therapy for caregivers improves the QOL of the care receivers or those who have been diagnosed with Alzheimer’s and/or other dementias. The results of such research could aid in planning for the growing population of individuals at higher risk for dementia. This planning could in turn promote better community QOL and decrease the community’s healthcare costs. Conclusion The main goal of the research was to infer whether or not caregiver education provided by an occupational therapist would be beneficial for the caregiver and client with dementia. It is evident that caregiver education does improve the QOL for clients with dementia and diminishes the burden of the caregiver. Much research supports the notion that if caregiver education is provided within the services from a health professional, the QOL will improve tremendously. The caregiver education may include factors such as coping strategies, educating on the client’s diagnoses, behavioral modifications, modifying the environment, and utilizing adaptive equipment within the environment.
