Abstract
This study analyzes the effect of social participation in a program that encourages participation in social activities as an approach to counteract the social isolation of elderly males in Japan. The design of this study was an open-label, before-and-after trial for a single group using the convergent design of the mixed-methods study. This program led to significant improvement in independent living and interest in society, but it did not help increase satisfaction with social activities. Additionally, a qualitative data identify that this program encouraged subjects to proactivity participate in social activities. While it has been identified that this program may have had a considerable effect by integrating quantitative and qualitative data, it is necessary to improve the program to further promote change in the subjects’ social behavior.

Social isolation is defined as the objective lack or paucity of social contacts and interactions with family members, friends, or the wider community (Valtorta & Hanratty, 2012). There is much less consensus around the accepted and agreed definition of social isolation; however, this is one of the most widely used definitions (Fakoya et al., 2020). It has been reported that the effects of social isolation and loneliness on mortality are about the same as smoking, and it is becoming a common social problem in developed countries (Holt-Lunstad et al., 2010).Social isolation is associated with increased mortality (Smith et al., 2018; Steptoe et al., 2013), and reduces the quality of life (Hawton et al., 2011). It is also associated with increased risk of cognitive decline and dementia (Fratiglioni et al., 2000; Glei et al., 2005; Kuiper et al., 2015). Isolated older people are more likely to develop functional disability, sleep disturbance, and depression (Choi et al., 2015; Saito et al., 2013). Absence of social participation, which is synonymous with social isolation, leads to high psychological distress (Oshio & Kan, 2019).
Several organizations combating social isolation have been established in different countries: Monalisa (Serres, 2016), which supports and collaborates with organizations in France; Coalitie Erbij Rotterdam (Mehrabi & Béland, 2020), which develops and disseminates knowledge and connects experts with support groups in the Netherlands; and the Reach Isolated Seniors Everywhere (RISE) campaign to promote actions by residents in Canada to reach out and connect with older people (Mehrabi & Béland, 2020). The problem is how to interact with other people in each country. According to the OECD (2005), Japan has the highest degree of social isolation among its member countries. Furthermore, in Japan, more than a third (35%) state that they have felt isolated or lonely for more than 10 years, compared with a fifth of those in the United States (22%) or the United Kingdom (20%) (DiJulio et al., 2018). The measures for long-term care prevention introduced by the Japanese government in 2006 were unsuccessful because of the failure to identify high-risk individuals and enroll enough participants in the community-based prevention program (Saito et al., 2019). Similarly, measures against social isolation were not implemented as in other countries. They look to prevent social isolation by building a community-based integrated care system in which inhabitants support each other regardless of age or disability. Measures specific to social isolation and involving the community are currently insufficient.
To prevent social isolation, it is important to engage in social activities that promote social participation. Social participation can be understood as activities that allow interaction in the wider society or the immediate community (Levasseur et al., 2010). Social participation refers to the levels of involvement of individuals with others in social activities. To counteract social isolation, it is important to strengthen participation by engaging in social activities.
Intervention programs to address social isolation are mainly developed as programs that strengthen social participation. Many interventions have been reported to be effective; the use of I.T., in the form of computers and smartphones; exchange programs; physical activities such as walking and Tai Chi; education related to falls prevention; cognitive behavioral therapy; psychotherapy (Elsherbiny & Maamari, 2018) in the form of reminiscence (Franck et al., 2016) and logotherapy; social activities, such as volunteer activities, and multifactorial intervention that combines these separate approaches (Pool et al., 2017; Takahashi et al., 2020). These programs are aimed at both males and females, but participants in major studies of social isolation have tended to be skewed toward female subjects (Fakoya et al., 2020). In Japan, older males tend to be more isolated than older females (Saito et al., 2009; Takahashi et al., 2020), and therefore, male-specific programs are pressingly necessary.
According to an integrated review by Gardiner et al. (2018), successful programs include adapting to the needs of participants, community development approaches, and engagement in productive activities (Cattan et al., 2003). In Japan, Fujiwara et al. (2009) revealed that the REPRINTS program, an intergenerational exchange program in which older people volunteer to read picture books with elementary school and kindergarten children, improves social networks and subjective understandings of health. To develop a program that meets these conditions, the author conducted an interview survey to clarify the issues that an older male living alone, who is at high risk of isolation, has in interacting with people. The results suggested that older males had a problem recognizing the problems arising in interacting with people, setting strategies for dealing with the problems, and altering daily activities. To prevent social isolation, a program based on a management process using occupational therapy that reconstructs the lifestyle and everyday seems to be effective. The purpose of this research is to verify the effect on the social participation engendered by the program.
Materials and Methods
Study Design
The study design was an open-label, before-and-after trial and a convergent design of mixed-methods research (Figure 1). The mixed-methods approach is the type of research in which the researcher combines elements of qualitative and quantitative research approaches (e.g., the use of qualitative and quantitative viewpoints, data collection, analysis, inference techniques) for the broad purposes of breadth and depth of understanding and corroboration (Johnson et al., 2007). The rationale for using this method is to clarify the extent of the effect from the quantitative data and then to clarify the experience of the subjects from the qualitative data. Furthermore, the rationale is to integrate both data sets and understand whether there is a needs-based intervention and the mechanism by which the subject has changed, both behaviorally and psychologically. These rationales have more important meaning for this study, which is the initial stage of effect verification (Moore et al., 2015). Both data sets were integrated after each analysis.

Program Description and Mechanism of Effect.
Subjects
The subjects were older males aged 65 and over who lived in the district located in the Tokyo metropolitan area. Physical mobility (i.e., being able to access the intervention venue independently) was a criterion for participation, and exclusion criteria were those who were hospitalized or living in care homes and those who had difficulty communicating. These conditions were assumed to be for a population that was beginning to feel constrained in social participation due to aging. Regarding the method of recruiting the subjects, we asked the local government in the district to display posters and introduce the participants to researchers.
Twenty-one people applied to participate in the study, but one of them dropped out due to a decrease in motivation before the program started (Figure 2). There were 20 participants with an average age and standard deviation of 73.1 ± 4.9 years; six in the classroom of the university and 14 in the nursing home (Table 1).

Research Ethics
The study was conducted according to the standards of the Declaration of Helsinki and was approved by the Ethics Review Committee of Tokyo Metropolitan University (No. 17078) and Mejiro University (No. 17-050). All subjects provided written informed consent.
Method of Program Development
The program was developed with reference to the methodologies for instrumentalizing complex interventions and previous scenarios on effective programs to prevent social isolation or promote social activities (UMIN000040535) (Cattan et al., 2005; Collins, 2014; Dickens et al., 2011; Robyn, 2003). It is important to prevent social isolation because it is difficult to take countermeasures after falling into social isolation. Therefore, this program engages in social activities to prevent social isolation. Participation in social activities is effective in preventing social isolation among older males in Japan (Ejiri, et al., 2018). In this research, social activity is defined as all activities in which older people voluntarily take part in their spare time, namely: interpersonal activities with others beyond family and relatives, activities carried out by participating in groups and organizations, and participation in community activities (Okamoto, 2010).
As the theory for strengthening the motivation of the subjects who engage in social activities, we used “the nine important aspects of occupational engagement” in the model of human occupation (MOHO), which is the theory of occupational therapy, namely, choose or decide, commit, explore, identify, negotiate, plan, practice, reexamine, and sustain (Kielhofner, 2008) (Tables 2 and 3).Simply doing an action is not enough for a person to change; it is important that a person chooses and is motivated, to participate in a meaningful activity in MOHO. Therefore, it is necessary to undertake activities that fulfill these nine aspects, to overcome older males’ hesitation to change and tendency to not take action. Each session of the program was structured to include these nine aspects, which must be changed for people to engage in social activities. The subjects used the checklist for the interest of the MOHO (Kielhofner, 2008), the social activity chart with a revised occupational questionnaire of the MOHO (Kielhofner, 2008), and the “checklist for vivid social activities” (Takahashi et al., 2000) as teaching materials.

Method of Program Implementation
This program was a group delivery approach and consisted of 120 min activities once a week for a total of 12 sessions. Each session consisted of lectures, exercises or experiences, and homework was given as required. The exercises were mainly to complete the teaching materials and discuss the themes.
At the beginning of the program, the participants consider the issues in their surrounding environment and social activities and learn the meaning of social activities in the community through discussions among themselves. Also, the participants analyze the use and importance of their time for social activities. During the program, the participants experience a change in themselves through learning about local resources and experiencing interesting social activities. At the end of the program, the participants make a plan so that they can change or maintain their social activities after the program ends. It is assumed that the effects of this program on the target population will be to reinforce their motivation to engage in social activities, to prepare and coordinate their preparation for social activities, and to increase their experience of the social activities that interest them (Figure 1). The final individual goals and outcomes of the program were increased satisfaction with social activities and increased social participation. The intention was to develop the ability to optimize participant engagement in social activities so that they would continue to participate in society, without being isolated from it, even after the program. In this way, by developing the ability to optimize their engagement in social activities, it is expected that the target population will continue to participate in society without remaining isolated.
The program was conducted at two venues, the classroom of the university to which the author belongs and the community room of the nursing home. The maximum number of participants at each venue was 15. In both cases, the first author and a male occupational therapist facilitated the program and collected data.
Program Trials and Modifications
Before this study, a trial effect was verified in four older males. As a result, the satisfaction with social activities improved before and after the program for all four subjects, and the participation status of valuable activities improved for three subjects out of four. However, the MOS 36-Item Short-Form Health Survey (SF-36) and the social support transfer scale (Social Support Exchange Scale: SSES) (Yaba & Ninomiya, 2010) did not identify a certain tendency (Nomura & Kobayashi, 2018). Therefore, it is necessary to reexamine the efficacy indexes. Also, the program structure was revisited so that the experience of social activities could be engaged with in parallel with lectures and exercises (Table 2).
Data Collection for the Quantitative Component
Since the concept of social isolation is not fixed and is difficult to measure, it is not possible to use the concept of social isolation as a target selection and efficacy index (Dickens et al., 2011). For the effect indicators of the program, it is necessary to measure the social participation of older males, so the following effect indicators were selected. The evaluation was conducted at the beginning and end of the program.
Baseline Characteristics
The subjects described on the fact sheet their age, hospitalization history, family living together, how often they meet family and relatives, how often they meet friends, whether they drive a car, whether they have a job, their financial status, and their completed academic background. The Kihon Checklist (KCL) (Suzuki, 2007) was used as an index to measure living functions. The KCL is composed of 25 items in seven areas of activities related to daily life, motor function, nutritional status, oral function, withdrawal, dementia, and depression. The total score was calculated from 0 to 25 points. The higher the score, the lower the degree of independent living.
Social Participation
The Index of Social Interaction (Anme et al., 2006) and the Self-completed Occupational Performance Index (SOPI) (Imai & Saito, 2010) were used as indicators of the social participation effect.
The ISI is an index that assesses the qualitative and quantitative aspects of the relationship between humans and the environment, which is measured by the presence or absence of human relationships in the local community and the frequency of relationships with the wider environment. It consists of 18 items in five areas: independence of life, interest in society, relationship with others, security, and familiar social participation. The minimum score is 0 and the maximum score is 18. The higher the score, the stronger the personal relationship with society.
The SOPI is a scale to measure the daily participation in activities that are valuable to individuals (occupational performance). It consists of nine items that ask about the three aspects of occupational performance (occupational control, occupational balance, performance satisfaction) in three areas of work (leisure activity, productive activity, self-care). The minimum score is 0 and the maximum score is 100. The higher the score, the better the performance of activities valuable to the individual in terms of occupational performance.
Satisfaction with Social Activities
Satisfaction with social activity was used in the Social Activities-Related Daily Life Satisfaction for the Elderly (SARDSE) scale (Okamoto, 2010). This scale consists of four factors, made up of 14 items: satisfaction with learning, satisfaction with contributions to others and society, satisfaction with health and physical fitness, and satisfaction with friends. The score is at least 14 points and the maximum is 70 points, which means that the higher the score, the higher the degree of satisfaction.
Program Satisfaction
Satisfaction throughout the program was investigated by the five-point method from “5. Very satisfied” to “1. Very unsatisfied” in the final evaluation.
Data Analysis Methods
Each efficacy index was analyzed quantitatively using the Wilcoxon signed-rank test or Mann-Whitney U test. SPSS Statistics ver.24 was used for analysis, and the significance level was set to 5%. Besides, the effect size r for each measured value was calculated using the test statistic z calculated by the nonparametric test. The effect size was judged to be small if 0.1 to less than 0.3, moderate if 0.3 to less than 0.5, and large if 0.5 or more (Cohen, 1988). Also, to identify the targets in which the program works effectively, subjects were divided into two groups, those with improved SARDSE and those with no improved SARDSE and analyzed by the Mann–Whitney U test for each effect index and basic characteristics.
Qualitative data were analyzed using the Steps for Coding and Theorization developed by Otani (2019). This analysis method consists of four-step coding using a matrix and a procedure that describes the storyline and theory by spinning the constructs. This method was developed to solve the problems of qualitative analysis such as coding, theorizing and opacity of the analysis process. It highlights the steps of the analysis using a matrix, including a mechanism to support the analysis of language. In addition, this method has the characteristic of preventing the arbitrary selection of data by researchers because all the collected data are used. This qualitative analysis was used in the research to extract the categories of public health nursing that strengthen the power of the community (Okamoto et al., 2019) and to clarify the concept of the care environment for caregivers (Nagai et al., 2020). The reason for using Steps for Coding and Theorization is that the storyline makes it clear what the subject has experienced. The analysis procedure considered one answer as one segment in a column of text and coded from the first step to the fourth step. The important words in the each segment was written in the first step named “Words to focus on in the text.” The words in the first step were reworded by analysts or a variety of words in the disciplines associated with the words; the second step is entitled “Words outside the text to reword the segment in the first step.” The background, conditions, causes, effects, comparisons, and characteristics to explain the words are included in the second step,” Finally, the third step is named “Words to explain the segment in the second step.” The theme was created based on the segment in the third step; the fourth step is called “Themes and constructs.” Then, to group the columns of the fourth step’s themes and constructs, each row (from text to the fifth step question/issue) was rearranged vertically. All lines (from the first step to the fourth step) were reviewed and the storyline and theory were described using all words in the fourth step.
Data Collection for the Qualitative Component
The free descriptions written on the 1st, 9th, and 12th sessions of the program were qualitatively analyzed. The questions in the first session were “Is there anything you have trouble doing in social activities?” and “What do you expect from this program?” The question for the ninth session was, “What kind of changes have you had in your feelings and social activities since you started participating in this program, and why do you think that has changed?” Questions for the 12th session were “What social activities did you have trouble with before that were solved by participating in this program?” and “What are the social activities you would like to start or continue after the program ends?”
Results
Program Implementation Results
The program started in May 2019 and ended in July as planned. The participation rate was 90.8%, 10.9 times per person, and there were no subsequent withdrawals. During the program period, two subjects rested multiple times due to operations and injuries. The family composition was seven living alone, eight living with a wife or parent, and five living with three children and a wife. Rate of satisfaction with the program after it had been run was “very satisfied” in 28% of the subjects, “somewhat satisfied” in 61% of the subjects, “neither” in 11% of the subjects, and “somewhat dissatisfied” and “very dissatisfied” in 0% of the subjects.
Quantitative Results
The total ISI score improved significantly (p = .011), and a substantial effect was recognized (r = .57) (Table 4). In addition, lower-order items of ISI, “subjectivity of life” (p = .038, r = .46) and “interest in society” (p = .046, r = .45), improved significantly and the effect improved. The effect size was medium. There were no significant differences in the other effect indexes, SARDSE, lower-order items of ISI, KCL, SF-36, and SOPI, and the effect size was small or almost nonexistent.

Qualitative Findings
Table 6 presents part of the analysis sheet via Steps for Coding and Theorization. First, the summary of the storyline is described below. Participants applied for the program in the hope of learning from each other and looking for future policies and sought to participate in this program for themselves at the beginning of the program. Through conversations between participants in similar circumstances, the scope and ideas of social activities expanded. Participants began to actively participate in social activities and changed their attitude to match their daily activities. The experience of social activities in the latter half of the program provided an opportunity to strengthen the focus on the community. Throughout the program, participants were directed to solve their individual challenges related to social activities.

Discussion
Characteristics of Participants
The average age of the 20 subjects in this study was 73.1 ± 4.9 years, and the median KCL score at the initial evaluation was 4.5. KCL has a positive correlation with the criteria for a frailty diagnosis by Fried et al., four to seven points indicate pre-frailty, and eight points or more indicate actual frailty (Satake et al., 2016). The results suggest that subjects were older males with pre-frailty who live at home. Besides, seven subjects were living alone, eight were living with their wife or parent, and five were living with their wife and children. The frequency of meeting with family members and relatives is polarized to 10 people for “every day” and eight people for “less than once a month,” and the “frequency of meeting friends” varies. Therefore, it was confirmed that the frequency with which the subjects met with another person varied greatly. Also, at the beginning of the storyline, “Participants participated in the program for the purpose of
Effect of the Program: ISI
The total ISI score improved significantly (p = .011) and a considerable effect size was observed (r = .57). In addition, independence of life (p = .038, r = .46), interest in society (p = .046, r = .45), which are lower items of ISI, improved significantly, and a moderate effect size was observed. “Independence of life” is composed of four items: the living arrangements, positiveness, consideration for health, and well-regulated life. In the second part of the program, “Looking back on the activities that a day comprises,” the participants gave careful consideration to how to organize their lives and consider their health. Also, the subjects considered that they were healthy and punctilious through their homework. Therefore, it is considered that the “independence of life” has improved. “Interest in society” consists of five items: subscription to books and magazines, use of appropriate tools, subscription to newspapers, conscious social contribution, and hobbies. ISI is an index that measures the qualitative and quantitative aspects of the relationship between human interactions and the environment in the local community, but the independence of life and interest in society represents the qualitative aspect. Therefore, the participants strengthened the qualitative connection with the community through the program. For example, the participants voluntarily arranged their own life and strengthened their awareness of social contribution.
There were no significant differences in the other effect indicators of ISI, namely SARDSE, KCL, SF-36, and SOPI, and the effect size was small or minimal. The results of the difference test between the two groups, those with improved SARDSE and those with no improved SARDSE, were that the 10 subjects with improved SARDSE had significantly lower SARDSE (p = .022), ISI interest in society (p = .025) and SOPI (p = .015) in the initial evaluation of the program (Table 5). The difference between the 10 subjects with improved SARDSE and the nine subjects without improved SARDSE was significantly lower for the total scores of SARDSE, SOPI, ISI, and lower items of ISI; “social concern,” “sense of security in life.” In other words, subjects with higher levels of social activity satisfaction and social participation before this program may be less affected, and conversely, subjects with lower levels of social activity and social participation may be more affected. In Arnetz’s (Arnetz, 1985) study, a social activity activation program for older adults of both sexes, subjects with lower initial levels of social activity improved their social activity levels. The present study and Arnetz’s study were similar in that subjects with low levels of early social activity improved their levels of social activity. Since SOPI includes “control of worthwhile activities,” the program was more effective for subjects who were not in prior control of their lives. This is the difference between the present study and that of Arnetz (1985). In the future, it will be necessary to add the level of social participation and the degree of control of life to the criteria for selecting participants to target groups that are highly effective in this program.

Limitations
There are three limitations of this study. First, because the program consists of one session per week for a total of 12 weeks and is a before-and-after trial for a single-group, the effect of a separate program or media from the main program is not excluded. Also, the effect may not be due to the program, but to the gathering effect. Thirdly, the generalizability is limited because the program was implemented in only one district in Japan and because the sample size was small.
Conclusions
The purpose of this study was to examine the effect on social participation of a program that encourages participation in social activities among older male participants. The design of this study was an open-label, before-and-after trial for a single group using the convergent design of mixed-methods study. By the outcome evaluation using quantitative data, this program significantly improved the independence of life and interest in society, and recognized a significant effect, but did not improve satisfaction with social activities. Through a process assessment with qualitative data, this program provided the participants with the experience of enhancing their commitment to social activities and was properly implemented. While it has been clarified that this program may have a considerable effect by integrating quantitative and qualitative data, it is necessary to improve the program to further promote change in the participants. It is necessary to identify more beneficial effects on social participation by conducting a controlled trial.
