Objective

To analyze the impact of pain intensity on depression levels among rural elderly individuals, and to explore the mediating role of Activities of Daily Living (ADL) and the moderating effect of internet use.

Methods

This study was based on the 2020 China Health and Retirement Longitudinal Study (CHARLS). Partial correlation analysis was used to explore the relationships between pain intensity, ADL, depression levels, and internet use among rural elderly individuals. The Bootstrap method (Model 4,58) was used to analyze the mechanisms through which ADL and internet use affect the relationship between pain intensity and depression levels.

Results

Pain intensity had a significant direct effect on depression levels among rural elderly individuals (β=1.537, 95% CI: 1.347-1.728). ADL played a significant mediating role between pain intensity and depression levels (β=0.319, 95% CI: 0.262-0.380). Internet use weakened the negative effect of pain intensity on ADL (β=0.508, P<0.01) and strengthened the negative effect of ADL on depression levels (β=-0.224, P<0.01).

Conclusion

Pain intensity positively influences depression levels among rural elderly individuals. ADL partially mediates the relationship between pain intensity and depression levels. Internet use moderates the effects between pain intensity and ADL, as well as between ADL and depression levels. Therefore, it is recommended to guide rural elderly individuals at the personal, family, and community levels to utilize internet technologies to disrupt the "pain-ADL decline-depression" chain reaction.
