Population is aging worldwide. There were 101.1 million older people—defined here as those aged 65 years and over—living in the European Union EU-28 at the start of 2018; this equated to almost one fifth (19.7%) of the total population. During the next three decades, the number of older people in the EU is projected to follow an upward path, peaking at 149.2 million inhabitants in 2050. Their relative share in the total population will also gradually increase and is expected to reach 28.5% in 2050 [1
]. Nevertheless, despite people living longer, the healthy life-year expectancy, i.e., the number of years free from disability, was estimated at 64.2 years for women and 63.7 years for men in the EU-27 in 2018 [2
]. This means that about 9 years of later life can be characterized by one or more age-related chronic diseases (multimorbidity), this resulting not only in a lower quality of life, but also in a dramatic increase of the healthcare expenditure [3
]. Thus, the increasing number of people with long-term care need is questioning the formal and informal healthcare systems sustainability due to the mismatch between care demand and availability of healthcare professionals and of public economic resources [4
In order to mitigate the effects of the aging population on the whole society, and in particular on the healthcare systems, 194 countries in the world, the European Union included, adopted the global strategy and action plan on aging and health (2016–2030), which is aimed at the full promotion of healthy aging, defined “as the process of developing and maintaining the functional ability (i.e., people’s capabilities of being and doing what they have reason to value) that enables well-being in older age” [5
]. The healthy aging concept embeds and partly advances the active aging paradigm [6
], meant as a process of optimizing opportunities for health and participation in the social, civic, cultural, and spiritual life realms for bettering the quality of later life [9
The global strategy and action plan on aging and health is also aligned with the 2030 Agenda for Sustainable Development Goals [10
], which aims to ensure that every human being can fulfill their potential in dignity and equality in a healthy environment. Hence, promoting healthy aging means adopting measures for preventing and delaying the onset of noncommunicable diseases and minimizing loss in autonomy by ensuring supportive environments, and effective healthcare systems for managing chronic conditions. Moreover, according to the WHO’s definition of health as a state of complete physical, mental, and social well-being [11
], the healthy aging concept goes beyond the concept of health as an absence of organic disease for, conversely, enhancing health in all its dimensions, i.e., social and psychological dimensions, and throughout the individuals’ life-course [7
]. In fact, circumstances throughout childhood and adult age influence health in old age, so people in all ages should adopt healthy behaviors such as balanced diet, constant physical activity, social contacts, and meaningful relationships, in order to pave the way towards a healthy and active aging, whose undermining factors are, conversely, isolation, invisibility, and loneliness [12
Within the older adult population, individuals aged between 55 and 70, including the so called older workers [13
] and new retirees, are worth special attention because the transition from work to retirement can expose them to the risk of poor health conditions and a lack of independence in absence of the adoption of a healthy lifestyle oriented toward physical activity, psychological well-being, and social participation [14
In fact, the literature is rather firm in stating that the transition from work to retirement is a life event that entails a complex psychological challenge, including leaving one’s professional life and organizing/enjoying the newly available free time [15
]. This transition may put individuals at risk of poverty, emotional discomfort, and isolation [16
], which can undermine people’s health [11
]. Nevertheless, there is not a general consensus in the literature on the impact of the retirement specifically on older adults’ health. Although some studies highlighted that retirement can improve the overall psychological and physical health of individuals [16
], others argued that the protective effect of retirement on the health status can change over time [19
]. Such an effect indeed, may be stronger for individuals who have been retired for less than two years, and still in the “honeymoon” stage [20
], and being weaker among people retired for more than two years who may live a “disenchantment” phase [21
]. According to the above, retirement is considered as a longitudinal process during which retirees’ levels of adjustment may fluctuate as a function of individual resources and changes in these resources [22
]. In the long-term, indeed, retirement can also mean the slowing down, if not the interruption, of cognitive stimuli, social relationships, and physical activity. This can compromise the image that older people have of themselves, diminish their sense of purpose, and lower the levels of self-esteem and self-efficacy, which may worsen both mental and physical health [23
]. As the years pass, loneliness and depression tend to increase among retirees, while mental health and satisfaction with life tend to decrease [15
Older people in the cusp of retirement may be concerned about their future and worried to jump into the unknown. They may be worried that retirement means inactivity and social exclusion and that they would become a burden for youngster family members (e.g., children) and for society. In particular, the fear of getting ill and declining health is fairly common [24
The extent to which retirees can take the retirement as a new opportunity for social participation and inclusion depends on endogenous factors, e.g., personal choice and exogenous factors like labor markets, pension, and welfare systems [25
]. Retirement also reflects societal values and cultural norms that influence older employees and retirees’ plans for retirement [26
]. For example, people who belong to family oriented societies may be more likely to spend time caring for older family members and grandchildren, while people with labor market oriented beliefs may be keener to re-enter the workforce [27
]. In this concern, previous research demonstrates that pre-retirement planning can predict post-retirement well-being and satisfaction [28
]. Nevertheless, in western developed countries, retirement satisfaction is most associated with good family relationships, social inclusion, and participation, e.g., volunteering and leisure activities, such as traveling, regardless of pre-retirement planning [30
In light of the above, retirement can be considered as a personal and not standardized process [31
] entailing many variables that can influence its course.
Therefore, carrying out health promotion interventions targeting older adults aged between 55 and 70 years, could be a strategy for early interception of their needs and keeping them healthy and active longer. Health promotion programs targeting this kind of end-user (i.e., people between 55 and 70, living the transition to retirement, or just retired), seem to be effective when they are shaped specifically for older adults by different means, e.g., photos, graphics, and videos with testimonies of people over the age of 50 who describe their health practices, difficulties, goals, and successes; when the activities suggested by the programs cover the major health promotion topics of healthy aging (i.e., diet, physical activity, stress management, and tobacco use); when longitudinal outcome assessments are included, and the outcomes help technicians shape and update further offered activities [32
]. Since retirement is a dynamic and very personal process [31
], the programs targeting older people in transition to retirement should be flexible and customizable in order to adapt to the constant change in physical, psychological, social, and economic determinants of health of the end-users.
The role that new technologies can play in enhancing older adults’ health and well-being is still an open question. In fact, despite the general interest around people in transition to retirement on one side, and the use of assistive technology for older people with disability on the other, there is still a paucity of studies exploring and experimenting the effectiveness of new technologies in promoting the healthy aging of people in this phase of life. Conversely, the current technology could be in a position to counteract social isolation and the emotional discomfort that may arise as a result of retirement, as well as to promote independent living and active and healthy aging of older adults by means of relatively simple assistive aids, as well as by high-tech solutions [32
]. In comparison to the traditional offline health promotion programs, online digital health promotion programs can not only improve diet behavior, physical activity, and social inclusion, but they can also have the advantage of being free or low cost, and accessible at all times and anywhere, such that the pressure on health systems (e.g., due to the increasing demand of workforce and expenditure for care) would be relieved and the assistance of an increasing number of elderly people with chronic diseases would be more sustainable.
Despite the promising bond between the aging and innovation trends, there can be several barriers to the use of technology by older adults. First, the common use of modern technologies by older adults in everyday life is not spread globally due to social factors (age, education, and gender), cultural characteristics of individuals (digital literacy and trust in technology), psychological issues (self-efficacy, comfort), and technological and economic factors (inequality access to technology, price-value) [34
]. Moreover, other barriers for using healthcare technologies have their roots in the technology design phase, and are the lack of acceptance, usability, and reliability of healthcare technologies by end-users. This approach is not recent by the fact that since 2005, according to McCreadie and Tinker [35
], the interactions between a “felt need” for assistance, the recognition of “product quality”, the efficiency, reliability, simplicity, and safety of the technology, and its availability and cost, are the basic components of a complex model of acceptability for assistive technology to older people. Similarly, Melenhorst et al. [36
] in 2001 suggested that the lack of perceived advantages or benefits might explain older adults’ reluctance to use digital technologies. An integrated approach to identifying enablers and barriers to older adults’ adoption of technology is proposed by Lee and Coughlin [37
], who classify common themes and concepts in the field of gerontology, information technology, behavioral sciences, human factors, consumer studies, and design. Factors such as usability, affordability, accessibility, emotion, confidence, independence, compatibility, reliability, social, technical support, and cost represent the complex and multiple aspects of a comprehensive understanding of older adults as users and consumers of technology, next to other factors commonly widely used under the umbrella of the technology acceptance model (TAM) [38
] and its various TAM extensions. Moreover, technologies need to match the needs of users without causing social embarrassment and stigma. For example, the functionality of assistive devices (i.e., age-related health monitoring devices could be perceived as disabling or lacking control), their aesthetics can also influence the relationship between product and user since technologies have symbolic meanings in contemporary societies and the way people use them can confirm and reinforce certain values [40
]. Therefore, the design of technologies should not interfere negatively with the process of acceptance. The latter aspects are still not easy to tackle despite being essential to ensure the effectiveness of the technology. The user centered design (UCD) [43
] approach is one of the most recognized for overcoming these barriers, because it ensures a continuous and iterative involvement of end-users for capturing their needs, capabilities, and limitations, in order to identify technology requirements and thus to develop technology that can meet users’ needs and expectations.
This study is part of the European project “Virtual coaching to support a healthy and meaningful life of older adults and employees in their retirement process” (AgeWell) (aal-2018-5-92-CP) that is aimed at developing a UCD personalized digital health coach (DHC) solution designed for supporting the healthy aging of older adults aged 55–70, especially of older workers and new retirees. The AgeWell DHC is an embodied conversational agent (ECA)—software specifically designed to work and act like a human. The advantage of this virtual humanoid character is almost similar to an in-person health coach offering self-management through personalized guidance and support available at any time and any location using a smartphone application. These characteristics make the DHC an inexpensive technology.
The study presented here is aimed at increasing the knowledge on the potential contribution of the DHC systems for promoting older adults’ healthy aging, thereby delaying intensive care needs and improving individuals’ independent life.
As mentioned above, the first focus group included five older workers, the second five retirees, and the third group embedded five colleagues of retirees or of older workers. In the cluster of older workers there were two women and three men aged between 60 and 66 years. Retirees were three women and two men aged between 62 and 70. The age range of colleagues of retired people was larger (between 37 and 58 years), and the group was made of three women and two men. Participants had different professional profiles: there were sociologists, administrative assistants, and health professionals. Table 2
reports participants’ characteristics and the user number associated with corresponding quotations reported in this section.
As mentioned above, according to the framework analysis, the chunks of focus-group transcriptions were associated to codes and the latter were merged in themes. Table 3
shows the correspondence between themes and codes.
In the following subparagraphs, participants’ feelings, needs, and expectations on retirement are reported, followed by individuals’ digital literacy and their feelings regarding expectations and risks of DHC use.
3.1. Feelings, Needs, Expectations, and Plans for Retirement
Older workers and retirees involved in the focus groups agreed on considering retirement as a breaking point and the beginning of a “new life”.
In the group of retirees, two main themes arose from the analysis of the sentiments: happiness for freedom and concern for the loss of social contacts, and showing ambivalent feelings towards the retirement. On one side, they realized having more time to devote to their interests and that they could plan their days as they preferred—they had been experiencing time free from work, duties, and working condition, as highlighted by a retired woman: “My PC password is “newlife”! I started a new life when I retired. I went back to being young. I go to bed very late (even at 2.30 am) and get up later. Positive aspects of retirement are gym three times a week, walking, theater, a few conferences, phone calls to elderly aunts, seeing friends” (P8).
On the other side, they complained about the loss of social contacts and the dearth of motivation and inputs for increasing social life. The two sides of the same coin are plastically described by the following quotation: “The positive side of retirement is freedom. The negative side is the interruption of many human relationships that gave me many stimuli (P6).
Other retirees pointed out more the freedom they were experiencing as retirees, underlying the power of working environment in conditioning thinking and daily activities: “I found freedom after 40 years of work” (P7), and “I can experience greater freedom to act and think without conditioning” (P10).
They also reported the need for more information about cultural events, e.g., concerts, conferences, art exhibition, because they thought that these events can represent chances for improving social life and stimulating brain activities. Someone highlighted the need for receiving advice on the opportunities and rights of pensioners.
As far as physical activity was concerned, most of retirees practiced gym and outdoor activities, such as sailing and walking, often regularly two or three times a week. The most common concern within this group was the fear of getting ill and having long-term care needs: “The biggest fear is that it doesn’t always go on like this: we age and aging brings disease. The hope is to maintain health as it is now and to allow my children a peaceful life; that is, that they do not have to assist me or help me financially to guarantee my care” (P10).
Older workers referred to being very busy for balancing work and family time. Older workers without family responsibilities, such as grandparenthood or caregiving for older parents, had time to spend in hobbies and interests. Moreover, they mentioned having an intensive social life and being in contact with many people they met at work and within their family and friendship network.
Within this group, the plans for retirement mainly concerned traveling and learning and, just in the case of a doctor, continuing working: “I would like to structure new private medical activities, but without excesses because I want to dedicate myself also to my wife and my grandchildren” (P3). Among older workers, fears related to retirement were not missing and they mainly concerned physical and psychological health, e.g., body weight increase, disability onset, and laziness, as depicted by the following quotations: “I’m afraid to get sick and not self-sufficient because I am aging […] and to become lazy, because of the lack of inputs” (P2).
Colleagues and excolleagues of older workers and retirees gave some interesting insights. In particular, they stressed that colleagues most attached to work felt the feeling of emptiness after retirement more than others. They agreed in pointing out that the reaction to retirement of their colleagues or excolleagues had been very personal and it depended on personal relationships (e.g., the presence of care responsibilities for grandchildren and/or very old parents), and on the attachment to work. The group of colleagues identified two possible reactions to retirement, described below: “Retirement is a very subjective aspect, but if I think of the person I am here for, I don’t think it will have great difficulties because she is always a very busy person with many things in mind, who knows how to work on herself, and I believe she will prepare in time and will be able to manage the sense of emptiness without suffering it” (P15) and “If I think of the person I represent, who has already retired, it is a woman extremely attached to work, which was the predominant aspect of her whole life and her main passion. I certainly know that you felt a strong emptiness when you stopped working” (P12).
3.2. Digital Literacy and Usage of Technology
The participants were asked about their level of digital literacy. Older workers as well as retirees used information and communication technology (ICT) daily and regularly: the first at work, e.g., e-mail and web platforms for sharing documents, the second for searching for public events, art exhibition, conferences, and for organizing their travels. Both groups surfed the internet in everyday life, searching for news and advice. Older workers as well as retirees were part of social networks, e.g., Whatsapp and Facebook, and they often communicated by means of them. All older workers used different types of apps on their smartphones, especially for monitoring physical activity, mostly walking. One retiree used a smartwatch.
In short, the use of technology was part of their life so we can say that they were digitally literate. Nevertheless, nobody was using a DHC, for neither physical activity nor other daily activities.
3.3. Feelings and Expectations on DHC
After explaining in words the DHC characteristics and possible functions, participants to the focus groups were asked to what extent a DHC could help them age healthy. Initially, retirees did not acknowledge the usefulness of a DHC for continuing living healthy because, in their opinion, the technology can be applicable mainly to older people with physical and cognitive impairment. Since they felt in good health condition, initially they did not find a DHC a useful device.
Older workers were very skeptical on the usefulness of the DHC for stimulating healthy lifestyle and, among the retirees the prevalent feelings were mistrust and suspect towards the DHC, which they look at like a manager giving orders: “In my opinion, retirement means also to respect one’s time. If I have a technology that pounds me all day, I no longer see respect for the pensioner. I don’t want to have schedules or programs anymore and I don’t want technology to force me to do what I have to do. I see it as a lack of respect for my timing and freedom. Moreover, what I want to do changes from day to day, so it would be very difficult even to personalize the digital coach inputs” (P4). Conversely, retirees were experiencing the freedom of being masters of their time, so they wanted to feel free to decide what to do day-by-day without restrictions.
In the group of colleagues of older workers and retirees, the first reaction was of skepticism towards the DHC that they found quite useless.
Conversely, after introducing DHC possible uses and functions via storyboards (Figure 1
), e.g., giving advice, motivating, monitoring physical activity, participants of the three groups were less skeptical and more confident in the usefulness of the DHC, and especially retirees were more open to the idea of using it.
Thus, the researchers started to explore with them the possible functions of this technical solution. The following paragraph reports participants’ inputs on the DHC functions, addressing the main objective of the USD approach, i.e., finding the meeting point between end-users’ needs and technology requirements.
3.4. Digital Health Coach Functions in Participants’ Opinion
Retirees suggested that the DHC had the function of (a) planning physical activity, travels, and social commitments; (b) stimulating interests and brain activities; (c) providing information on cultural and social events; and (d) giving advice on economic and legal issues related to retirement. Especially the planning function was unanimously stressed by retirees because it was meant as a useful tool in order not to waste but to fully exploit the free time they had at their disposal.
The group of older workers and the group of colleagues/excolleagues agreed that motivating older adults to adopt healthy lifestyles should be the main function of the DHC. The second function could be to prepare older adults to retire by enhancing their self-awareness and helping them to identify their needs and desires. Finally, the group of colleagues/excolleagues emphasized the potential of the DHC in connecting older people virtually by building small communities.
All participants of the three groups agreed that a DHC should be an avatar running on the smartphone. The latter, being portable, was deemed respectful of the freedom of retirees who finally can move and travel without work time restrictions.
The DHC was unanimously acknowledged as a useful tool to facilitate the transition to retirement: “The digital coach should intervene before retirement to prepare people for what will happen. Indeed, many people do not have the opportunity to prepare for retirement.” (P1).
An excolleague of a retiree suggested the use of the DHC by companies in order to accompany the person towards the retirement during the last years of work: “Companies should offer a guidance service to older workers to help them understand how they can happily experience the transition to retirement.” (P11).
Colleagues and excolleagues agreed on the fact that “the digital coach should be attractive and fun: something like a game” (P12). Moreover, the identification of the specific needs of this target emerged as an essential prerequisite to design a technology that can meet the individuals’ preferences, thus being fully acceptable, usable, and effective: “The digital coach should ask the subjects some questions to know health, socialization, and well-being needs. Therefore, based on the answers, the digital coach should propose a series of activities compatible with the subject preferences.” (P11).
Within the group of older workers arose the necessity of a DHC meeting the numerous changes that people have to face during the transition from work to retirement. These changes concern financial aspects, social activities, health, and life style, as depicted by the following quotation: “There is an economic change, a change in health, in legislation, in educational initiatives, and in facilitations for pensioners. People often don’t know a lot of things because they never got information before they retired. They have so many opportunities that they do not know because they do not care until they are retired, so it may be useful to inform them before the transition to retirement” (P1).
3.5. Risks within the Usage of the Digital Health Coach
Participants identified three main risks in the use of the DHC: stigmatization, privacy violation, and substitution of human beings’ cognitive and decision capabilities. The following quotations depict each of these risks.
“Needing a virtual coach like this means being old and not self-sufficient…it makes me feel even older.” (P14).
“An avatar works well only if it is connected with personal data management tools. So there could be a privacy problem.” (P13).
“For healthy people, the digital coach is useless: it is foolish to let me do things that I can do. Delegating these activities to these technologies damages the maintenance of my autonomy.” (P10).
The respondents identified two measures for overcoming these limitations: (a) a correct programming of the digital coach and (b) the involvement of a human being for facilitating the use of this technology: “It would be useful if there was an operator collaborating with the person who has to retire, sets up and customizes the product, and carries out a sort of accompanying function” (P11).
This study was aimed at collecting end-users’ attitude and expectation towards the use of a DHC for exploring the potential of this kind of technology in promoting older adults’ healthy aging. To this purpose, three focus groups with older workers near to retire, retirees, and their colleagues/excolleagues were carried out in Italy.
In line with the literature [15
], findings showed that retirement was generally meant and experienced as an existential change and as a fundamental step towards a new life by both older workers and retirees participating to this study. Retirees had ambivalent feelings about their experience of retirement, swinging between sense of freedom and sense of emptiness, especially due to the loss of social relationships, this confirming what was underlined by previous studies on retirement [22
]. They referred to being concerned for their health and they were especially worried to have long-term care need in a near future, and to lose their independence. They expressed the need to be informed about social, educational, and cultural events, and retirees’ rights.
As well, older workers seemed to be quite concerned for their physical health and psychological well-being after retirement. They were fully aware and conscious of the risks of retirement; i.e., loss of cognitive stimuli and social contacts and depression, but also of the potentialities of this change i.e., the chance of having more time, the freedom, and the sense of being masters of their own life [58
Older workers and retirees taking part into this study had a good level of health and digitally literacy. Indeed, they recognized the ubiquitous use of technology and innovative solutions in everyday life, e.g., by using different typologies of apps, thus confirming that the stereotype of older adults as sick, unable to learn, slow, disinterested in new activities, and technophobic has been left behind by the last generation of new retirees [34
]. Therefore, older adults were likely to use a DHC to stay healthy before and after retirement. The DHC was expected to provide them with information about social and cultural events and the rights of older people and pensioners. They would also like a coach that could adapt to their needs and motivate them to a healthy lifestyle.
It is worth mentioning that at the beginning of the discussion, it was quite challenging for focus-group participants to imagine how the technology could meet their needs for health. This might depend on the fact that they felt well and had no health condition (in fact, being in good health was one of the inclusion criteria). Moreover, there was a prejudice among the participants related to the technology, which they considered useful just as assistive device for older people with disabilities. In essence, the participants failed to understand the potential of the DHC as a preventive means in the hands of people who are still healthy and fully self-sufficient like them. As consequence, in the participants’ opinion, the usage of the DHC might lead to the stigmatization of older users as sick and disabled. This suggests that the first step towards the acceptance of this type of technology is the knowledge of what it can offer and of its potential. This knowledge can lead to the deconstruction of stereotypes and to a better perception of the technology that can be accepted only when older adults see a benefit from its use [59
]. Obviously older adults with low digital literacy cannot fully take advantage from the DHC and therefore they cannot enjoy all its benefits. For this reason, any program based on the use of a DHC should be introduced by training to develop both digital literacy and health awareness, such that individuals can develop e-health literacy [37
], and so fully exploit the potential of the DHC. The good health and digital literacy of participants opens the scenario of an increasingly larger segment of technology users over the next few decades being more conscious about their attitudes toward barriers and drivers to the use technology. In fact, the idea to have a DHC was lively discussed within the three groups. Someone defended the freedom of being master of one’s own time after retirement, i.e., the chance for choosing what to do, when, and where, without the interference of the DHC. Conversely, someone else underlined the need for planning this time in order to make it fruitful (i.e., free but not empty) by means of the DHC.
In light of the above, the DHC challenge seems to stand on the capability of reaching a balance between the user’s decision-making capability and the DHC stimulation and motivation. The solution to this dilemma may lie on the synthesis of universal (inclusive) design concept [63
], and on a customized, flexible, and smart programming based on users’ personal interests, designed in an end-users-driven perspective [43
4.1. Innovations and Limitations
To our best knowledge, this is one of the few studies on the use of a DHC aiming at promoting older adults’ healthy aging in its meaning of a multidimensional concept going beyond the physical health and embedding even its social and psychological determinants. This study, indeed, has two innovative aspects.
The first lies in having focused attention on a group of older adults, aged between 55 and 70 years, who are often overlooked by research on the development and use of technology. This is due the fact that most of the attention of the scholars in this field has been paid to technology targeting older people with long-term care needs and so with assistive more than with preventive functions. On the contrary, the involvement of people in the 55–70 age range may allow prompt interception of the needs of a group of people who are entering old age and starting a new phase of life marked by retirement.
The second element of innovation lies in considering the DHC system as a technology whose potential is still underexplored, especially when applied to older adults in transition to retirement and for purposes related to healthy aging.
The principal strength of this study was the involvement of people in different stages of life, i.e., older workers and retirees who could give their personal opinion on aging, retirement, and health, thus providing a dynamic perspective as required by a dynamic process such as the transition from work to retirement. This study provides several insights on what people between 55 and 70 years may think about the possibility of being supported by the technology for aging healthy and about which may be the role of a DHC in promoting healthy and independent life of retirees. Nevertheless, this study was not without limitations.
First, the restricted number of participants as well as the specific Italian national context and culture, i.e., representations of work, retirement, technology, national legislation on retirement [27
], do not allow the generalization of the outcomes. Moreover, the study did not consider several factors, such as social class, cognitive ability, and education, which might influence the pathway to retirement and the life after retirement [65
]. In fact, the participants involved were characterized by a medium-high level of education and by a good digital and health literacy, which could have influenced their responses, oriented the general trend of the choral discussion, and hidden the barriers to technology use that are often common among (older) people with lower education, income, and social inclusion [34
]. Third, the whole sample was characterized by an active adoption of technologies and use of the internet that might have created a bias on participants’ perspectives, since having experiences with technology during the working life can shape attitudes towards the use of technology later in life [34
]. Furthermore, no gender analysis was carried out, due to the limited number of the Italian sample participants. Nevertheless, the gender perspective will be considered for the investigation of future longitudinal cross-national data emerging from the AgeWell project.
4.2. Suggestions for Future Research and Policy
From these limitations, some suggestions for future research can be derived. First, more studies exploring the efficacy of DHC systems in supporting health and well-being of older people in transition from work to retirement are recommended, because this topic is still underdeveloped. Second, it is suggested that people in different life phases be involved in these studies, as it has been done in this study, which involved older workers, retirees, and their colleagues/excolleagues. In fact, this may allow for gathering multiperspective opinions on the representations of aging, retirement, health, and use of technology, since these concepts change throughout the course of life. Moreover, we suggest adopting a mixed-method approach in future research on this topic. As retirement is a personal experience indeed, the qualitative approach may ensure to capture the different ways to interpret this experience, while the quantitative approach involving large samples may support the generalizability and the transferability of findings. Furthermore, cross-national studies on the current topic are recommended for supporting the comparability of the outcomes read through the lens of the national legislative, cultural, social, and economic context, as well as further investigations. Future studies should also involve participants with different educational levels, economic conditions, and sociocultural origins in order to assess possible correlation between these variables, the representations of health and retirement, and the trust in the efficacy of DHC systems supporting healthy aging.
Finally, the recent coronavirus pandemic has forced many governments to take measures of physical distancing, which has often become social distancing, of people for containing the infection, thus introducing further complications to health and well-being especially among older adults [66
]. In similar situations, when it should be not possible to meet in person and to attend gyms and public spaces, the DHC could motivate older adults to continue carry out physical activity, create cultural and entertainment moments, and build new relationship spaces through the creation of virtual communities where activities and results could be shared. DHC could thus mitigate the consequences of physical distancing and help the elderly to continue walking on the path of healthy aging by practicing physical activity at home [67
]. In this concern, public policies would be welcome which support digital and health literacy and the adoption of simple, user-friendly, and not expensive digital solution that, like the DHC, may promote healthy lifestyles among all older adults, even those with fewer economic opportunities and a medium-low level of education.
