Aim: We developed a scale to measure the social activities of community-dwelling older men requiring support. Methods: The participants were a group of 134 men, ≥65 years old, who required support and were living in Hokkaido, Japan. An anonymous questionnaire was administered through individual interviews. Valid responses were obtained from 121/134 interviewees. The construct validity of the resulting scale was assessed by exploratory factor analysis (EFA). Criterion-related validity was tested with Spearman’s rank correlation test based on the Social Activities Index for Elderly People (SAI-E). Reliability was assessed by Cronbach’s alpha. Results: A Social Activities Scale for Community-dwelling Older Men Requiring Support (SASOMS) scale was created, comprised of the following three subscales: daily interactions with familiar people; intimate relationships with family members; and interactions with others through activity programs (e.g., exercise, games, recreation, etc.). The created SASOMS scale correlated with the SAI-E (r = 0.557), and its criterion-related validity was confirmed. The alpha coefficient of the new scale was 0.791, and its internal consistency was confirmed. Conclusions: The reliability and validity of the developed SASOMS scale was confirmed, demonstrating that it can be used to assess social activities specifically in older men requiring support. Our results suggest that the scale can be used effectively by care providers who support older men requiring care. The usability of the SASOMS should continue to be improved, and it is necessary to verify its validity in longitudinal studies.
A low birthrate is accelerating population aging in Japan to a greater extent than in any other nation in the world. In 2017, persons aged 65 years and older accounted for 27.3% of the Japanese population [
Japan’s current policies promote a variety of key service providers, including local residents and private businesses, among others, which promote livelihood support and provide preventive care services for older persons. These policies are designed to encourage participation in social activities to support the maintenance of purpose in daily living [
Social activity scales can be administered by care providers to promote and maintain the social activities of older persons. The Social Activities Index for Elderly People (SAI-E) was developed in 1997 to evaluate social activities among healthy older adults [
Because social behavior differs between men and women, it is necessary to develop a social activities scale for men requiring support. To address this need, we developed the Social Activities Scale for Community-dwelling Older Men Requiring Support (SASOMS). This scale can be used together with existing psycho-physical assessments to evaluate social activity participation of elderly men requiring support and it can be used to inform the provision of services appropriate for actual needs.
This study was approved a priori by the Ethics Committee of Hokkaido University Faculty of Health Sciences (June 9, 2016, no. 16 - 24). The participants were men aged 65 years and older men who met the following criteria: 1) certified as requiring level 1 or 2 support for long-term care; and 2) not diagnosed with a cognitive disorder. The target region was three municipalities in Hokkaido, northern Japan. Enrollment was based on “population-scale” and “urban or rural” considerations. City A is situated in an urban area, with a population of 120,000 persons, including 33,000 persons aged 65 years and older. Town B and Town Care in outlying regions. Town B has a population of 9,200 persons, with 3,600 persons aged 65 years and older. Town C has a population of 17,000 persons, with 5,400 persons aged 65 years or older [
We requested recruitment cooperation from the three municipalities, and 134 people were contacted. The study was explained verbally and in writing to participant by staff at a community general-support center and researchers. Eleven people withdrew from the study due to health reasons or hospitalization.
The survey period was August 2016 to March 2017, with 123 participants. The survey was administered at participants’ personal residences. The survey consisted of individual interviews in which respondents’ answers were recorded on anonymous questionnaires. To improve inter-rater reliability, the interviews were conducted by certified public health nurses, social workers, care managers, researchers, research assistants with experience as public health nurses, and support center employees. A survey manual clarifying procedures was distributed to all participants beforehand.
The survey addressed age, living arrangements, required care level, subjective health, and 25 tentative SASOMS items. The SAI-E was used for assessment of criterion-related validity; it has four domains: individual activities, social participation/voluntary activities, learning activities, and work [
Tentative SASOMS items were based on the social activities of older men certified as requiring support [
A group of seven older men requiring support were asked the following questions: (1) Do scale items reflect the social activities of older men requiring support? and (2) Are scale items easy to understand? Their responses confirmed that the tentative SASOMS items were appropriate as is. A 5-point Likert scale was used for Tentative SASOMS item responses: 5, almost every day; 4, once or more times a week; 3, once or more times a month; 2, once or more times a year; and 1, not at all. Higher scores indicated a higher frequency of social activities.
Mean values are reported with standard deviations (SDs) to refine scale items, we performed the following item analyses: inter-item correlation, comparison mean values ± SDs, good-poor (G-P) analysis, and item-total (I-T) correlation analyses. G-P analysis divides total scale scores at the mean value into a high group and a low group, and calculates the mean-value difference between these two groups. I-T analysis calculates correlation coefficients between each item and total scale scores of all other items.
The scale’s construct and criterion-related validity were examined with exploratory factor analysis (EFA) and concurrent validity analysis, respectively. For the EFA, factor numbers were set using three factors based on the three concepts of social activities engaged in by older men requiring support. The unweighted least-squares method was used with factor loading in the selection of items of 0.35 and above, and a promax rotation was performed. For the concurrent validity analysis, Spearman’s rank correlation coefficient was determined between SAI-E and tentative SASOMS items scores. To examine the scale’s internal consistency, Cronbach’s alpha reliability coefficient was calculated.
Because three communities were targeted, the homogeneity of the respondents was investigated with respect to their residential areas and basic attributes (sex, living arrangements, level of required care, and subjective feelings of health) were examined. Relative distributions of respondent characteristics were analysis with the Mann-Whitney U test, Kruskal-Wallis test, chi-square test, and Fisher’s exact test. All statistical analyses were carried out in IBM SPSS 22.0 J for Windows, with level of significance level of 5%. Alpha coefficients <0.7 were considered unsatisfactory [
Analysis was performed on the 121 persons who responded to all of the tentative SASOMS items (response rate, 90.3% of 134). The participants’ had a mean age of 81.69 ± 7.27 years; their characteristics are summarized in

The participants were a group of 134 men, ≥65 years old, who required support and were living in Hokkaido, Japan. The participants met the following criteria: 1) certified as requiring level 1 or 2 support for long-term care; and 2) not diagnosed with a cognitive disorder.
floor or ceiling effects were not excluded because we determined that these items were indispensable for assessment of our concepts of social activities in older men requiring support.
G-P analysis indicated that for all items except 12, 13, and 17, the scores of all participants in the high-score groups were significantly higher than the scores of all participants in the low-score groups (all p < 0.05). In the I-T analysis, for all items except 13 and 17, the correlation coefficient obtained was at least 0.2. Based on these statistical results, the four items 12, 13, 17, and 21 were excluded.

“interactions with others through activity programs” included two items. Respective contribution rates of these three factors were 32.68%, 15.13%, and 12.34%, respectively, with a cumulative contribution rate of 60.15%. Criterion-related validity analysis demonstrated that all three SASOMS factors correlated moderately with the individual activities domain of the SAI-E. Meanwhile, factor 1 correlated moderately with the social participation/volunteer activities domain and correlated, albeit not as strongly, with the learning activities domain of the SAI-E. The two scales, on the whole, were found to be well correlated. The Spearman’s rank correlation coefficients and associated significance levels for all correlations between these two scales and their domains/factors are reported in
For the SASOMS overall, we obtained a Cronbach’s alpha reliability coefficient value of 0.791, thus demonstrating internal consistency. The Cronbach’s alpha values for factor 1, factor 2, and factor 3 were 0.802, 0.849, and 0.841, respectively. Regarding the relationship between respondent attributes and SASOMS score, as shown in

We measured the social activities of older men requiring support, and developed a 10-item, three-factor scale. Because the resultant SASOMS items were created based on prior research [
The SASOMS had more concrete social activity items than the SAI-E. That is, the SASOMS appears to be an effective scale for measuring the unique social activities of older men requiring support, activities that are not measured directly by scales that measure the social activities of healthy older people. The participants in the present study had considerably lower scores than those of a prior survey of 1,500 randomly selected older adults in Japan, in which older men obtained SAI-E scores of 1.7 for participation/volunteer activities, 0.5 for learning activities, and 6.9 for individual activities [
Previously, the social activities domain of the SAI-E has been defined as “human interactions fostered through interaction with other persons in society and the local community” [
Regarding content validity, although the factor structure correlated with the conceptual framework that the scale was based on, adopted items were reduced by around half. Items eliminated because of the factor analysis results addressed activities performed by an individual alone and those involving interactions with healthcare workers and care providers. These items had a weak relationship with our stated concepts. Regarding criterion-related validity, the SASOMS correlated significantly with the SAI-E, and among the SAI-E domains, with the individuals’ activities domain most robustly [
The inherent decline in the instrumental activities of daily living of older persons requiring support obliges a change in the kind of social activities they engage in. SASOMS factors 1 - 3 correlated with the individual activities domain of the SAI-E, and factor 1, in particular, correlated moderately with the social participation/volunteer activities of the SAI-E, indicating that the SASOMS is conceptually similar to the individual activities and social participation/volunteer activities domains of the SAI-E.
Our analysis of SASOMS scores in terms of ages and living arrangements revealed an effect of older age (>75 years) on factor 1 scores. Japanese people in their early 70 s and early 80 s are known to have more intimate acquaintances with neighbors than their 65 - 69-years-old compatriots [
Notably, men living with family had higher scores for “intimate relationships with family” and higher SASOMS total scores than those living alone. In a nationwide survey in Japan [
The social activities of healthy older people tend to favor items 3 - 6 (see
This study had some limitations. First, our small sample size and specific communities surveyed limits the generalizability the results. Second, although the reliability and validity of the SASOMS was verified, its usability should be verified by future studies. Third, due to time limitations, we did not verify predictive validity or responsiveness in the analysis strategy. Future longitudinal studies are needed to further verify the validity of this scale.
In conclusion, the SASOMS should be effective in the provision of support by care providers for older men requiring support. First, it can be used by care providers to measure the characteristics of social activities of older men requiring support. Scale total scores measure the overall activities of such men, while comparison of the ratios for scores across the three subscales can demonstrate their specific social activities. Second, when the SASOMS is used together with activities of daily living and instrumental activities of daily living assessments, one can better investigate the living-activity interventions required by older men requiring support. Use of the SASOMS may thus help to expand the scope of daily life and improve quality of life. Third, the SASOMS can be used to monitor intervention efficacy because it measures the effects of social activities-related support provided for older men requiring support.
