Abstract:

With the rapid popularization of short-video platforms, the phenomenon of short-video addiction among older adults has
gradually become prominent, emerging as a social issue that urgently requires attention. However, current research on the influencing
factors of short-video addiction among older adults remains relatively scarce. Through the analysis of data from 314 paper
questionnaires, this study explores the impacts of subjective and objective social isolation on short-video addiction among older adults
and their underlying mechanisms. The results show a significant positive correlation between subjective social isolation and short-video
addiction among older adults, while objective social isolation has no significant effect on short-video addiction. Further analysis reveals
that loneliness and online social support play a significant chain mediating role in the influence of subjective social isolation on short
video addiction among older adults. These conclusions provide a new perspective for understanding how social isolation affects short
video addiction among older adults through psychological and social pathways, and are of great significance for formulating targeted
intervention strategies.
