Effectiveness of Intergenerational Interaction on Older Adults Depends on Children's Developmental Stages; Observational Evaluation in Facilities for Geriatric Health Service.

The demand for intergenerational exchange is growing in the world, where the size of a family is becoming smaller. To promote intergenerational exchange, it is important to know whether different stages of child age have different effects. This study aimed to examine effects of intergenerational exchange using children at different developmental stages through a questionnaire survey. The subjects were 296 employees of 116 facilities for geriatric health services that routinely conduct intergenerational exchanges. A questionnaire was designed to ask the employees what effects were observed on old adults and on the employees themselves after intergenerational exchanges were conducted. The results indicated that younger children caused better effects both for older adults and for the employees regarding some of the items, while older children caused equal or lesser effects for all items. It was suggested that the developmental stage of children should be considered according to the purpose of intergenerational exchange.
