The widespread prevalence of Alzheimer's disease and other dementias accounts for one in three deaths among adults 65 years and older in the United States [1]. Asian American families of individuals with dementia often seek help in later stages of the disease, and some dementia sufferers remain undiagnosed [2]. Research has documented significant barriers to dementia care for underserved Asian Americans in California, including lack of health insurance, low income, limited English language ability, stigma surrounding dementia, and low health literacy [2]. In fact, many Asian Americans continue to believe that dementia is a normal part of aging [3]. They avoid diagnosis and treatment for dementia until the late stage, and underutilize available public health services [3]. Orange County has a diverse population of older adults, including 66% Caucasian, 14% Hispanic, and 17.5% Asian [4]. In some areas (e.g., Westminster and Garden Grove), the Asian population constitutes 50%–60% of residents [5]. Orange County has the largest numbers of Vietnamese Americans living outside of Vietnam, and more than 30% of Korean Americans live in Southern California. These two ethnic minority groups have the highest rates of poverty (12% in Vietnamese Americans and 17% in Korean Americans) of all ethnic minorities ages 65 and over [56]. In Orange County, the Asian population is 62% foreignborn and the fastest growing ethnic population. Tragically, the death rate of Alzheimer's disease in Orange County increased 36% between 2006 and 2010 [6], which is higher than the California or national rates [7].

Internet- or phone-based interventions have been implemented to support dementia patients' caregivers [38]. However, little is known about the relevance and effectiveness of these interventions for ethnic minority caregivers. Asian Americans are the fastest-growing ethnic group in the United States, yet they remain an understudied group in relation to dementia care. More research is needed to highlight their unmet needs and to inform the development of educational interventions for this population.

The purpose of this study was to identify Vietnamese American and Korean American dementia patients' family caregivers' in usages of computers and smartphones as well as their caregiving needs in order to develop a dementia care education program for these groups.

With an aging society and the global increase in immigration, immigrant families with persons with dementia suffer greatly due to limited knowledge of dementia-specific social and healthcare services. This may be rooted in culture, especially for Asian immigrants, who traditionally have Confucianism as their main ethical belief system; filial piety is expected of adult children (especially the eldest son) who are expected to take care of their parents [9]. This may lead to delays in Asian immigrant families seeking help when a family member shows signs of dementia; they are hesitant to rely on senior care facilities as it may seem that they are not fulfilling their filial duties to their parents with dementia [10]. In addition, Buddhist Asian immigrants often consider illness as punishment for misbehavior [9].

This study focused on identifying technology use among dementia family caregivers of ethnic minorities currently living in the United States. (i.e., Vietnamese and Korean). Ultimately, the study results may assist in developing culturally sensitive and person-centered dementia care education interventions for vulnerable ethnic minority populations affected by dementia. Our findings revealed that dementia caregivers more often use smartphones than computers. In particular, almost all Korean American participants reported that they used social media apps (i.e., Kakao Talk) for sending messages, pictures, or short video files while communicating with others through audio and video chats. Vietnamese American participants also reported that they use various social media apps to communicate with others. These results are in agreement with the general current trend in technology use; Asian Americans are the most frequent users of the Internet, broadband at home, and smartphones in comparison to other ethnic groups, such as Caucasians, African Americans, and Hispanics in the United States [11].

Prior studies on internet-based interventions for informal dementia caregivers resulted in increased confidence, decreased depression, and enhanced self-efficacy as well as lower costs [12]. The findings were based on computer-based Internet programs [12]. Mobile technologies, including smartphones, tablets, and other wireless devices, serve as platforms of self-management interventions for chronic diseases (e.g., cancer, diabetes) [1314]. Examples include features for remote symptom monitoring as well as the provision of programmed clinical advice through automated text messaging, web browsing, email, or video [14]. With the widespread use of smartphones among the Asian population, smartphone-based interventions could address the unmet needs of many dementia family caregivers who cannot leave home to take advantage of in-class education because they need to stay at home to care for their loved ones with dementia.

In addition to mobile-based approaches, multi-focal intervention methods (combinations of conventional methods and technology based methods) should be considered to support various dementia caregivers, including spouses, adult children, siblings, relatives, and/or friends/neighbors. Support for families affected by dementia can be found in the general community, such as the work of volunteers who possess a genuine calling to serve vulnerable dementia patients and their families. Partnerships with university students, religious groups, and local ethnic communities would enhance the impact of dementia care education, particularly in efforts to reduce caregiver stress and institutionalization of dementia patients [15].

This study had some limitations. The sample size was small, and data were collected in a specific regional area. However, little research has been conducted on this ethnic minority population of family dementia caregivers. We conducted this study as a preliminary work before we move on to develop culturally appropriate and people-favorable methods for dementia caregiver education and intervention for stress management in this specific population. Our approach can provide an example for other ethnic groups in dementia care research.

The findings from this study showed that most dementia family caregivers in the ethnic minority groups studied use smartphones more often than computers. Over half of those caregivers use social media apps to communicate with others. A smartphone app-based caregiver intervention could serve as a more effective approach in comparison to the conventional in-class method.

In conclusion, as Asian Americans are likely to be digitally adept, mobile-based dementia care education for Asian family caregivers may be an effective complement to traditional educational methods, such as onsite education using paper-based handouts. Multiple modalities in the development of caregiver intervention should be considered.
