Development of Older Adults' Perceptions on Community-based Connectedness with People Scale: Reliability and validity evaluation.

AIM

We developed a self-assessment scale-Older Adults' Perceptions of Community-based Connectedness with People-to assess older adults' comprehensive perceptions of their connectedness with others in the community. A specific aim of this study is to evaluate the reliability and validity of this scale.

METHODS

Participants consisted of 1000 men and women aged 65 years or older, living in Sapporo, Hokkaido, Japan. Factorial validity was assessed using exploratory and confirmatory factor analysis, while concurrent validity was assessed using correlation analysis. Reliability was confirmed by Cronbach's α coefficient using the internal consistency method, and the stability coefficient was confirmed using the test-retest method.

RESULTS

Responses were received from 380 participants, and 358 participants who responded to all items were included in the analysis. The developed scale comprised 22 items with three factors: "Perception of Inclusion" (α = .947), "Perception of Reciprocity through Reception" (α = .937), and "Perception of Reciprocity through Provision" (α = .910). Correlation analyses indicated that concurrent scales were positively correlated with Ikigai and negatively correlated with loneliness on the total scale. The model fit was comparative fit index = 0.933, goodness-of-fit index = 0.854, adjusted goodness-of-fit index = 0.818, and root mean square of approximation = 0.081. The stability coefficient of the total scale scores was 0.875 (95% CI: [0.830, 0.908]).

CONCLUSIONS

The developed scale had adequate reliability and validity. The perceptions of connectedness measured using this scale can be used by public health and nursing care professionals to prevent loneliness and isolation among older adults living in the community.
