Purpose: This study aimed to verify the direction of providing and receiving intergenerational support and examine its effects on mental health among intergenerational non-relatives.
Materials and methods: In the initial survey (Time1), approximately 65,000 residents of Wako City in Saitama Prefecture, Japan, were considered, from which, a sample of 7,000 people was obtained. A total of 2,982 valid responses was received, and a follow-up survey was conducted two years later (Time2).
Results: Structural equation modeling with a cross-lagged effect model and a synchronous effect model showed that the direction of giving and receiving intergenerational support had changed with age; while the young and middle-aged groups shifted their direction from receiving support to giving support, the older adults shifted their direction from giving support to receiving support. Furthermore, in the young-adults group, receiving support from older adults positively influenced their mental health two years later. For the middle-aged group, giving support positively influenced their mental health at Time2. For the old-old group, receiving support from young and middle-aged people positively influenced the mental health at Time2.
Conclusions: To facilitate intergenerational mutual help in the local community, it is necessary to create opportunities for older adults to provide support to young and middle-aged people and, in return, create a mechanism to prompt support from young and middle-aged people for older adults.
