BackgroundIn an aging society, it is necessary to promote successful aging by helping older adults maintain engagement in social activities, especially after retirement. Focusing on psychological independence is critical for helping community-dwelling older adults maintain their ability to do things independently and build appropriate relationships with neighbors. However, shifting one’s mindset from the workplace to the local community can be difficult, especially for Japanese people who prioritize work over local community activities. Few studies have investigated the factors associated with the psychological independence of community-dwelling older adults, so this study examined the factors influencing the psychological independence of older adults in T town, a typical commuter town in Japan.MethodsA self-administered, anonymous questionnaire was distributed to 246 neighborhood association members aged 65 and older. T-test, Pearson’s correlation coefficient, Cronbach’s alpha, and multiple regression analysis were used to develop a model for predicting psychological independence and its two subconstructs, purposefulness and personal accountability.ResultsThe results demonstrated that psychological independence, purposefulness, and personal accountability were significantly predicted by having abilities that are useful to other people (β = 0.399, p = 0.001; β = 0.277, p = 0.019; and β = 0.394, p = 0.001, respectively).ConclusionThe findings suggest that older adults can maintain psychological independence using their existing characteristics, such as hobbies and life skills that are useful to others in the community.
