AIM: Although some previous studies have suggested using a social networking service (SNS) to create and maintain offline social networks among younger generations, whether similar outcomes would apply to middle-aged and older individuals is uncertain. This study aimed to examine the association between participation in groups via SNS and greater offline social networks among middle-aged and older individuals. METHODS: We conducted a web-based questionnaire survey on 3106 respondents from September to October 2021 among members of "the Shumi-to Club," an SNS in Japan. They indicated the number of SNS groups they belonged to and were classified into two categories, namely, those with and without participation in SNS groups. The current study assessed offline social networks using the total frequency of face-to-face interactions with distant family members and friends. Ordinal logistic regression analyses were performed, and the frequency of offline interactions was set as the outcome with adjustment for sociodemographic variables and self-rated health. RESULTS: Approximately 70.8% (n = 2200) of the participants belonged to SNS groups. Participation in SNS groups was associated with higher frequencies of face-to-face interaction with friends (odds ratio [95% confidential intervals]: 1.78 [1.53-2.07]). However, the current study found no association between belonging to a group and face-to-face interaction with distant family members (1.09 [0.93-1.26]). CONCLUSIONS: The participation in SNS groups potentially promotes offline social networks, particularly with friends. Geriatr Gerontol Int 2024; 24: 279-284.

AIM: This study aims to elucidate what volunteering activities mean for older adults in Japan by analyzing their emotions and evaluations from hedonic (e.g., happiness), eudaimonic (e.g., self-growth), and social (e.g., social coherence) well-being. METHODS: The qualitative research was conducted to describe the subjective experience of older adults' volunteering activities (frailty checkups) in the community-setting. Eight older adults were interviewed about their experiences during these activities. The interview data were analyzed from two assumption frameworks: first, three aspects of well-being, and second, timeframes of well-being, during the activity, medium-term, and long-term. Previous studies have not focused on the polysemy or the timeframe of well-being. RESULTS: Our results showed that hedonic, eudaimonic, and social well-being are not independent, but overlap. Furthermore, even if older adults experience certain emotions at a point of time, they may change in the long term. This implies that it is important to analyze older adults' feelings and experiences from not only one aspect but from different perspectives and measure their feelings not just at a particular moment but in the long term. This is the first empirical study to examine qualitatively the holistic experiences of well-being among older adults who volunteer. CONCLUSIONS: We conclude that this study is unique in that it attempted to associate empirically the experiences of older adults during volunteering with their general psychological status of well-being. These findings could help make volunteering activities more meaningful for older adults and create or promote an active community. Geriatr Gerontol Int 2024; 24: 273-278.

Every research participant has their own personality characteristics. For example, older adults assisted by socially assistive robots (SAR) may have their own unique characteristics and may not be representative of the general population of older adults. In this research, we compared the average personality characteristics of participants in a workshop on robotics recruited directly through posting with those of older Japanese adults to examine participant selection bias and group representativeness for future study of SARs. After a one-week recruitment period, the workshop was attended by 20 older participants (nine males and 11 females) aged between 62 and 86 years. Extroversion among workshop participants was 4.38, 0.40 higher than the average for older adults in Japan. The workshop participants’ openness was 4.55, 1.09 higher than the average for the Japanese elderly. Thus, the results indicate a slight selection bias in the personal characteristics of the participants depending on the recruitment method when compared to the Japan national average for older adults. In addition, only one of 20 participants was below the cutoff on the LSNS-6 score and considered to have a tendency toward social isolation. The development and introduction of socially assistive robots is often being considered to support people in social isolation in their daily lives; however, the results of this study showed that it is difficult to recruit people who tend to be socially isolated when gathering research participants by methods such as posting. Therefore, the effectiveness of the method of recruiting participants should be carefully verified in research regarding socially assistive robots.
